Referring to FIG. 11, the shield 840 includes a plurality of pixels, and the light transmittance (or light transmittance) of each pixel may be controlled independently.

Through this, the present invention can control the light transmittance of at least a portion of the plurality of pixels included in the shield 840 so that at least a portion of the light generated by the light source unit 810 is blocked.

By including a plurality of pixels and controlling light transmittance of at least a portion of the plurality of pixels, the present invention can provide a vehicle lamp capable of irradiating light with various beam patterns.

Specifically, the shield 840 of the present invention may include a plurality of pixels 840a and 840b, as shown in FIG. 11. In addition, each of the plurality of pixels 840a and 840b (or each pixel) included in the shield 840 may be formed to independently control light transmittance.

The plurality of pixels 840a and 840b may be arranged in a matrix format, as illustrated in FIG. 11. A wire receiving a control signal may be connected to each of the plurality of pixels. As another example, a plurality of pixels may be grouped into at least one group, and wirings for receiving control signals for each group may be connected to control light transmittance for each group.

For example, each group may be grouped by at least one row or by at least one column. That is, according to an embodiment of the present invention, the present invention is the shield 840 included in the shield 840

In this specification, it will be described as an example that the wiring is connected so that a control signal is received for each of a plurality of pixels so that control can be performed independently for each pixel.

Meanwhile, as illustrated in FIG. 11, each pixel 844 may be formed to partially change the light transmittance.

For example, a first region 844a and a second region 844b may be included in one pixel, and the light transmittance of the first region 844a and the second region 844b within one pixel may be It can be formed differently.

That is, each pixel included in the shield 840 of the present invention may be formed to partially change the light transmittance.

For example, each pixel included in the shield 840 may be applied to all kinds of configurations (material, technology, material) capable of changing light transmittance. For example, each pixel has a liquid crystal (LC) film, a liquid crystal display (LCD), a stretch film, an ITO film, etc., in which light transmittance is varied according to the intensity of an electrical signal (for example, current, voltage, or power). It can be formed as.

The shield 840 of the present invention may be referred to as a matrix shield, display shield or variable shield.

The vehicle lamp 800 of the present invention may include a processor 870 that controls the light transmittance of the shield 840.

The processor 870 may control components included in the vehicle lamp 800. As described above, the processor 870 may be a lamp driver 650 or a controller 170.

The vehicle lamp 800 of the present invention may form various types of beam patterns by controlling light transmittance of a plurality of pixels included in the shield 840.

For example, the processor 870 may allow a portion of the plurality of pixels to pass light so that the beam pattern generated by the light passing through the shield 840 has a cut-off line 841. Can be controlled.

When outputting a low-beam (downlight) from the vehicle lamp 800, a predetermined cutoff line must be generated (satisfied) according to laws and regulations.

For example, the cut-off line is generated when the light is irradiated to a plane (for example, a wall surface) spaced a predetermined distance from the vehicle lamp 800 (or the vehicle 100), and is generated above the area where the light is radiated. It can be defined as the boundary (line).

The cutoff line may refer to a boundary line in which the brightness of light exceeds a reference value as light is irradiated to the plane.

As illustrated in FIGS. 12A and 12B, the shape of the cutoff line may be differently defined according to laws (or countries, regions, states, cities, etc.).

For example, in a country (region, state, etc.) designated for vehicles to pass on the right side, as shown in FIG. 12 (a), a low beam pattern (or cutoff line) with a lower left side than the right side is irradiated (generated). ). As another example, in a country where a vehicle is designated to pass on the left side, as shown in FIG. 12B, a low beam pattern (or cutoff line) on the right side lower than the left side should be irradiated (generated).

This is to prevent light from being irradiated to the other vehicle traveling in the opposite direction (or in the opposite direction), thereby preventing glare from being generated by the driver of the other vehicle.

The processor 870 may determine the current location of the vehicle 100 equipped with the vehicle lamp 800 based on the information received from the location information unit 420. In addition, the processor 870, based on the current location, the light transmittance of the plurality of pixels included in the shield 840 so as to irradiate a low beam pattern corresponding to a law applicable to the country (or region, state). Can be controlled.

The processor 870, as shown in FIGS. 11 and 12, controls a portion of the plurality of pixels of the shield 840 to pass light (for example, by controlling light transmittance to 0), so that it is low. Light can be irradiated (output, generated, transmitted) so that a beam pattern is generated.

Specifically, when a portion of the plurality of pixels (eg, 842a, 842b, 842c) is controlled to transmit light so that light does not pass (controlling light transmittance to 0), the light generated from the light source unit 810 may be The light directed to the portion where the light transmittance is set to 0 is blocked by the shield 840 (specifically, a portion of the pixels whose light transmittance is controlled so that the light does not pass), so that it cannot be directed to the lens 850.

Accordingly, only the light from the light source unit 810 that is directed to a portion where the light transmittance is not 0 passes through the shield 840 and is irradiated to the lens 850. In addition, light irradiated to the lens 850 may be transmitted to the outside through the lens 850 to generate a predetermined beam pattern (eg, a low beam pattern or a cutoff line).

Meanwhile, the shield 840 of the vehicle lamp 800 related to the present invention may be formed (controlled) so that each of the plurality of pixels transmits only a part of the light (or the amount of light) received from the light source unit 810.

For example, the light transmittance of each pixel may be controlled to transmit only a portion of the received light amount. For example, assuming that light corresponding to 100 is received at a specific pixel, and if the light transmittance of the specific pixel is set (controlled) to 50%, the specific pixel is 50 of the light (light amount) corresponding to the 100. Only light corresponding to (light amount) can be transmitted. Accordingly, the brightness of the light passing through the corresponding pixel is reduced (in other words, the brightness of the portion of the beam pattern generated by the light passing through the corresponding pixel may be darkened).

As such, the processor 870 may independently control the light transmittance of the plurality of pixels included in the shield 840 to generate (irradiate) various patterns of light.

For example, as illustrated in FIG. 11, the light transmittance of a pixel included in a first portion 842a among a plurality of pixels is set to 50%, and included in a second portion 842b different from the first portion The light transmittance of the pixel is set to 20%, and the light transmittance of the pixels included in the third part 842c different from the first and second parts is set to 0%, thereby outputting a beam pattern having a gradient effect ( Survey, generation).

That is, in the case of FIG. 11, the light transmittance of a plurality of pixels included in the shield 840 is set to gradually increase along one direction (for example, an upward direction), so that the front of the vehicle lamp 100 (optical axis direction) It is possible to implement a gradation effect (ie, an effect that becomes lighter or darker along a predetermined direction) on the beam pattern irradiated with.

Meanwhile, the processor 870 may differently control a portion of the plurality of pixels that does not pass (or opaque) the light, based on whether the light incident from the light source unit 810 is direct light or reflected light.

Referring to FIG. 10, the light source unit 810 of the present invention may be implemented to reflect light generated from the light source 822 to the reflection unit 830 to be incident on the shield 840. In this case, the light source unit 810 includes at least one light source 822 (or one or more light sources) and a reflector 832 formed to reflect light generated from the light source 822 toward the shield 840. can do.

10, a cross-sectional view of the vehicle lamp 800 of the present invention taken along line A-A is shown.

Referring to (a) of FIG. 10, the vehicle lamp 800 of the present invention may include a first light source 822a and a second light source 822b.

The first light source 822a may be formed to output light in an upward direction. The second light source 822b may be formed to output light in a downward direction.

The reflector 830 may include a first reflector 830a and a second reflector 830b. The first reflector 830a may be an upper reflector disposed on an upper side based on an imaginary axis horizontally crossing the center of the reflector 830.

The second reflector 830b may be a lower reflector disposed below the virtual axis that horizontally crosses the center of the reflector 830.

According to (a) of FIG. 10, light generated from the first light source 822a is reflected by the first reflector 830a and can be directed to the shield 840 (eg, the upper end of the shield 840). have.

The light 1 generated by the first light source 822a and reflected by the first reflector 830a may form a low beam pattern. This is because light generated upward from the first light source 822a is reflected by the first reflector 830a and irradiated downward.

That is, the first reflector 830a may be a reflector for forming a low beam pattern.

In addition, the light generated from the second light source 822b may be reflected by the second reflector 830a to be directed to the shield 840 (eg, the lower end of the shield 840).

The light h generated by the second light source 822b and reflected by the second reflector 830b may form a high beam pattern. This is because light generated downward from the second light source 822b is reflected by the second reflector 830b and irradiated upward.

That is, the second reflector 830b may be a reflector for forming a high beam pattern.

When outputting a low beam, the processor 870 may turn on only the first light source 822a and turn off the second light source 822b. On the other hand, when outputting a high beam, the processor 870 may turn on the first light source 822a and the second light source 822b together, or only the second light source 822b.

Meanwhile, FIG. 10B illustrates a case where the vehicle lamp 100 includes one light source 822. In this case, the light source 822c may be formed to generate light toward the rear opposite to the front.

A reflector 830 may be provided behind the light source 822c. At this time, the reflector 830, the first region (corresponding to the first reflector 830a) disposed on the upper side with respect to the virtual axis horizontally crossing the center, and the second region disposed on the lower side (second) It may include) (corresponding to the reflector 830b).

Among the light generated from the light source 822c, light reflected by the first area 830a of the reflector forms a low beam pattern, and light reflected by the second area 830b of the reflector is high beam. A pattern can be formed.

This means that the light emitted from the light source 822c to the first region 830a of the reflector is reflected downward by the first region 830a to pass through the lens, and This is because the light irradiated to the second region 830b is reflected upwardly by the second region 830b and passes through the lens 850.

10 (a) and 10 (b), although there is a difference between one or two light sources, the paths of light forming the low beam pattern and the high beam pattern may be the same / similar.

That is, in the case of (a) and (b) of FIG. 10, light generated from the light source unit 810 and irradiated (incident) to the shield 840 corresponds to reflected light.

On the other hand, referring to (c) of FIG. 10, when the light source 822d is a laser light source LD, the light source 822d may be formed to emit light forward. In this case, the light source unit 810 may not include a reflection unit 830.

Light emitted from the light source 822d is directly incident on the shield 840. That is, in the case of Fig. 10 (c), the light generated by the light source unit 810 and irradiated (incident) to the shield 840 corresponds to direct light (or direct light).

Among the light generated from the light source 822d, light directly directed to the upper end of the shield 840 may form a high beam pattern, and light directed directly to the lower end of the shield 840 may form a low beam pattern.

Here, the upper end of the shield 840 may include at least one of pixels disposed above the center of the shield among the plurality of pixels, and the lower end of the shield 840 is the center of the shield among the plurality of pixels At least one of the pixels disposed below may be included.

When the light incident from the light source unit 810 is reflected light, the processor 870 may control pixels of the first portion of the plurality of pixels of the shield 840 to pass light. In addition, when the light incident from the light source unit 810 is direct light, the processor 870 controls the pixels of the first part and the second part of the plurality of pixels of the shield 840 to pass light through. You can.

For example, when outputting a low beam, the processor 870, when the light incident from the light source unit 810 is reflected light, as shown in FIGS. 11 and 12, among the plurality of pixels of the shield 840 Pixels of the first portion (eg, lower portions 1210a and 1210b) may be controlled to pass light through. In this case, the pixels of the second portion (eg, the upper portion 1210c) of the plurality of pixels of the shield 840 may be controlled by the processor 870 to pass light.

In the case of reflected light, the beam pattern 1200c generated through the shield 840 is vertically inverted with the portion 1210c whose light transmittance (for example, light transmittance 100%) is controlled (set) to pass light. Or it can be flipped upside down, left and right.

This is because light emitted from the light source is irradiated downward when reflected by the upper reflector (or upper region of the reflector), and irradiated upward when reflected by the lower reflector (or lower region of the reflector).

The same principle can be applied to the case of inverting left and right. When the reflector has the shape of a hemisphere, the light emitted from the light source is irradiated in the right direction when reflected by the left reflector (or the left area of the reflector), and left when reflected by the right reflector (or the right area of the reflector) Because it is irradiated in the direction.

In the present specification, as illustrated in FIG. 12, the shape of the beam pattern 1200c through which the reflected light passes through the shield 840 is a light transmittance (eg, light transmittance) so that light is passed through the shield 840. It will be described as an example that 100%) is a form inverted up and down in the form of the part 1210c that is controlled (set).

However, depending on the shape of the reflector 830 (or the reflectors 830a and 830b, the shape of the beam pattern 1200c is based on the shape of the portion where the light transmittance is controlled to pass light through the shield 840). It may be inverted upside down, left and right.

On the other hand, although not shown, when outputting a low beam, the processor 870, when the light incident from the light source unit 810 is direct light (or direct light), different from the first portion of the plurality of pixels of the shield 840 Pixels of the second portion (eg, the upper portion 1210c of the shield 820) may be controlled to pass light through. In this case, pixels of the first portion (eg, lower portions 1210a and 1210b) of the plurality of pixels of the shield 840 may be controlled by the processor 870 to pass light.

In the case of direct light, the beam pattern 1200c generated through the shield 840 is a part of portions 1210a and 1210b whose light transmittance (for example, light transmittance 100%) is controlled (set) to pass light. It can correspond to the form. This is because the light forming the low beam pattern is not reflected by the reflector, and is generated by passing through the lens 850 after passing through the shield 840 directly, so it is not inverted or inverted.

In summary, when outputting a low beam (or when generating a low beam pattern), in order to form a low beam pattern, the processor 870 may allow a portion of the plurality of pixels of the shield 840 to pass light through. The light transmittance can be controlled.

At this time, the processor 870, the light source unit 810, depending on the type of light incident on the shield 840 (in other words, the presence or absence of a reflector) of the plurality of pixels to pass through the light is different.

For example, the processor 870, when the light incident on the shield 840 from the light source unit 810 is reflected light (in other words, when a reflector is present), a first portion of a plurality of pixels (eg, a lower portion) In can control the light transmittance of the pixels included in the first portion so that the light does not pass. The first portion may be formed to include a cutoff line in a low beam pattern.

As another example, if the light incident on the shield 840 from the light source unit 810 is direct light (in other words, if a reflector is not present), the processor 870 may include a second part different from the first part of the plurality of pixels ( For example, the light transmittance of the pixels included in the second portion may be controlled so that light does not pass at the upper portion). The second portion may also be formed to include a cutoff line in the low beam pattern.

On the other hand, when a request for a high beam output is received, the processor 870 may change at least a portion of the portion that does not pass light to pass the light.

For example, when the light incident from the light source unit 810 to the shield 840 is reflected light, the processor 870 receives light among a plurality of pixels of the shield 840 based on receiving a high beam output request. The light transmittance may be controlled so that light passes through at least a portion of the first portion (lower portion) controlled to pass through.

As another example, when the light incident from the light source unit 810 to the shield 840 is direct light, the processor 870 is based on receiving a high beam output request, and the light among the plurality of pixels of the shield 840 is not lit. The light transmittance may be controlled so that light passes through at least a portion of the second portion (top portion) controlled to be excessive.

On the other hand, the processor 870 of the present invention, the light transmittance of a plurality of pixels included in the shield 840 can be independently controlled to control the shield 840 to output light of various beam patterns according to the situation. have.

Specifically, the processor 870 may sense information related to the vehicle using the sensing unit 120 provided in the vehicle. The information related to the vehicle may be at least one of vehicle information (or a driving state of the vehicle) and surrounding information of the vehicle.

For example, the vehicle information includes: a vehicle driving speed, a vehicle weight, a vehicle occupant, a vehicle braking force, a vehicle maximum braking force, a vehicle driving mode (whether autonomous driving mode or manual driving mode), a vehicle parking mode (Autonomous parking mode, automatic parking mode, manual parking mode), whether the user is on board the vehicle and information related to the user (eg, whether the user is an authenticated user).

The surrounding information of the vehicle is, for example, the state of the road surface (driving force), the weather, the distance from the front (or rear) vehicle, the relative speed of the front (or rear) vehicle, and the driving lane is a curve The curvature of the curve, the brightness around the vehicle, information related to the object existing in the reference area (constant area) based on the vehicle, whether the object enters / departs into the predetermined area, whether the user exists around the vehicle, and the user It may be information related to (eg, whether the user is an authenticated user) or the like.

In addition, the surrounding information (or surrounding environment information) of the vehicle includes external information of the vehicle (for example, ambient brightness, temperature, sun location, surrounding subject (person, other vehicle, signs, etc.) information, and the type of road surface being driven. , Terrain features, lane information, lane information), and information necessary for autonomous driving / autonomous parking / automatic parking / manual parking mode.

In addition, the surrounding information of the vehicle includes an object (object) existing in the vicinity of the vehicle and a distance to the vehicle 100, the type of the object, a parking space where the vehicle can be parked, and an object for identifying the parking space (for example, Parking line, rope, other vehicles, walls, etc.) may be further included.

In addition, the information related to the vehicle may include various driving modes set by user input.

For example, as illustrated in (a) of FIG. 13A, when the processor 870 satisfies a preset first condition (for example, the vehicle is driving in a lane adjacent to the sidewalk through the sensing unit 120). Sensing, or to set the user attention mode by the user), among the plurality of pixels of the shield 840 to output light corresponding to the first beam pattern corresponding to the first condition among the plurality of pixels It is possible to control the pixel of the portion associated with the first condition to pass light through.

As another example, as illustrated in (b) of FIG. 13A, the processor 870 may satisfy a preset second condition different from the first condition (eg, the current location of the vehicle 100 is town) A plurality of pixels of the shield 840 in order to output light corresponding to a second beam pattern (a second beam pattern different from the first beam pattern) corresponding to the second condition among the plurality of pixels. Among the pixels, the pixels associated with the second condition may be controlled to pass light through.

(A) of FIG. 13a is set to the user attention mode, (b) of FIG. 13a is set to the town mode, and (c) of FIG. 13a is set to the country mode, (b) of FIG. a) is set to the light output mode in a specific weather (for example, snow or rain, etc.), Fig. 13b (b) is set to the highway mode, and Fig. 13b (c) irradiates light to a specific object It shows the beam pattern and the light transmittance of the shield when the object tracking mode is set. As illustrated in FIGS. 13A and 13B, the processor 870 has different portions through which light is not passed through the shield 840 to form different beam patterns according to each mode (or a preset condition). The shield 840 can be controlled.

In addition, the processor 870 of the vehicle lamp of the present invention, when another vehicle (that is, the vehicle opposite) that is traveling in a direction opposite to the direction in which the vehicle 100 is traveling is detected, light is irradiated to the other vehicle To prevent this, the light transmittance of the shield 840 can be controlled.

For example, as illustrated in (a) of FIG. 14A, in the state in which the light transmittance of the shield 840 is set to output the first beam pattern, the other vehicle traveling in the opposite direction through the sensing unit 120 Can be detected. In this case, the processor 870, as shown in (b) of FIG. 14, the shield 840 to block the light to the area (space) (1400a, 1400b) to which the light is irradiated by the other vehicle The light transmittance of at least some of the plurality of pixels 1410a and 1410b may be controlled.

For example, the processor 870 may block the light irradiated to the first space among the plurality of pixels of the shield 840 so as to block the light irradiated to the first space where the driver of the other vehicle is located ( The light transmittance of 1410b) can be set to 0%.

As another example, the processor 870 is irradiated to the second space among the plurality of pixels of the shield 840 so that the amount (or brightness) of light irradiated to the second space corresponding to the area surrounding the other vehicle is reduced. The light transmittance of the pixel 1410a through which light passes may be set to a predetermined transmittance (eg, 20%).

Through this configuration, the vehicle lamp of the present invention can implement the Antiglare High-beam Assist function that prevents light from being irradiated to the vehicle opposite.

As another example, as illustrated in (c) of FIG. 14, light is irradiated to a space including both sides and a predetermined height of the vehicle 100, and light is not irradiated to other spaces 1400d. The processor 870 sets a predetermined transmittance (for example, 20%) of a light transmittance of a portion 1410c through which light irradiated to the space 1400c corresponding to the predetermined height among a plurality of pixels of the shield 840 passes. ). In addition, the processor 870, the other portion of the plurality of pixels of the shield 840, the light irradiated to the space other than the above (1400d) of the shield 840 passes through the other portion 1410d so that light is not irradiated to the space 1400d other than the above ) Can be set to 0%.

As another example, as shown in (a) of FIG. 15, the processor 870, in the general driving mode, blocks at least a portion of the light incident from the light source unit 810, so that the first and The light transmittance of the second group 1510 or 1520 may be controlled. For example, the light transmittance of the pixels belonging to the first group 1510 may be 40%, and the light transmittance of the pixels belonging to the second group 1520 may be 0%.

In this state, when the processor 870 detects a specific object (eg, a person) within a certain distance from the vehicle 100 through the sensing unit 120, the spaces 1524 and 1514 in which the specific object exists ), So that the light transmittance of the shield 840 can be controlled.

For example, the processor 870 may, based on the detection of the specific object, detect a pixel 1512 through which light irradiated to a portion 1514 of the space among pixels belonging to the first group 1510 passes. The light transmittance can be changed. For example, the light transmittance of the pixel 1512 is changed from 40% to 100%, so that a large amount of light is irradiated to a portion 1514 of the space. Here, the portion 1514 of the space may be a space that directly includes the sensed object.

In addition, the processor 870, based on the detection of the specific object, the light of the pixel 1522 through which light irradiated to the other portion of the space 1524 of the pixels belonging to the second group 1520 passes. The transmittance can be changed. For example, the light transmittance of the pixel 1522 is changed from 0% to 60%, so that the other portion 1524 of the space is irradiated with a smaller amount of light than the portion 1514. The other portion 1524 of the space may be a space around the sensed object.

Through such a configuration, the vehicle lamp 800 of the present invention can not only output a beam pattern corresponding to the object detection mode in an optimized manner, but is also irradiated to the surrounding space along with the space where the detected object directly exists. A precise beam pattern that can be output by adjusting the amount of light can be realized.

On the other hand, the processor 870 of the present invention, as shown in Figure 11, a region adjacent to a region (for example, a region having a light transmittance of 100%) adjacent to a portion through which light passes, as shown in FIG. The light transmittance of 842a may be set to a predetermined transmittance.

For example, when the light transmittance of the pixels included in the adjacent area 842a is set to 0% to pass light, the processor 870 may adjust the light transmittance of the pixels included in the adjacent area 842a. It can be set to a predetermined transmittance (for example, 50%).

Through this, the present invention can provide a vehicle lamp capable of blurring (or modulating) a cutoff line boundary when outputting a low beam pattern.

When the low beam pattern is output, the present invention makes it possible to solve the conventional problem that the visibility of the cutoff line is poor because the light does not reach the upper portion of the cutoff line.

In addition, in the present invention, when light is excessively irradiated to the lower portion of the cut-off line, and light is irradiated with another vehicle traveling in the opposite direction even when outputting low beam due to movement of the vehicle body due to unevenness of the road surface, causing glare, By blurring the cutoff line boundary and reducing the amount of light around the cutoff line, the accident occurrence rate can be significantly lowered.

In addition, the vehicle lamp 800 of the present invention may include a sensing unit 120 for sensing information related to a vehicle.

The processor 870 may set the light transmittance of the adjacent area to the predetermined transmittance based on the information related to the sensed vehicle satisfying a preset condition.

Specifically, when the information related to the sensed vehicle corresponds to a first preset condition, the processor 870 may set the adjacent region to a first light transmittance (eg, 80%). In addition, when the information related to the sensed vehicle corresponds to a second preset condition different from the first condition, the processor 870 may change the light transmittance of the adjacent region from the second light transmittance different from the first light transmittance ( For example, it can be set to 60%).

For example, the preset first condition may include a situation in which it is necessary to slightly change the boundary of the cutoff line of the low beam pattern. For example, in the preset first condition, when the surrounding brightness of the vehicle lamp 800 (or the vehicle 100) is brighter than the reference brightness, the vehicle 100 may generate a specific road (eg, a highway). In the case of running, it may include a case in which another vehicle traveling in the opposite direction exists within a certain distance from the vehicle 100 or the vehicle 100 is driving downhill.

As another example, the preset second condition may include a situation in which it is necessary to more faintly change the boundary of the cutoff line of the low beam pattern. For example, in the second condition, when the ambient brightness of the vehicle lamp 800 (or the vehicle 100) is darker than the reference brightness, the vehicle 100 may use a specific type of road (eg, a dirt road). , A one-way street, etc., when there is no other vehicle traveling in the opposite direction within a certain distance from the vehicle 100 or when the vehicle 100 is driving uphill.

The embodiments listed above are merely examples, and are not limited to the above embodiments, and the first and second conditions may include more various conditions. Also, the first and second conditions may be determined or changed by user settings.

On the other hand, the processor 870, if the information related to the vehicle that satisfies the preset condition (first and second conditions) through the sensing unit 120 is not detected, the light transmittance of the adjacent area to the original state Can be restored.

For example, an area adjacent to a portion through which light passes (a portion 842a in FIG. 11 or 1200b in FIG. 12) among portions that do not pass light before satisfying a preset condition (or a line 841 corresponding to the cutoff line) ), The light transmittance of the pixel included in the region may be in a first value (eg, 0%). In this state, the light transmittance of the adjacent area 842a is a second value different from the first value under the control of the processor 870 based on the sensing of information related to a vehicle that satisfies a preset condition ( For example, 50%).

Then, the processor 870, if the information related to the vehicle that satisfies the preset condition is not detected (or, if the information (or state) related to the vehicle that satisfies the preset condition is released), the adjacent area ( The light transmittance of 842a) may be restored (or changed) from the second value to the first value.

On the other hand, the processor 870 of the vehicle lamp 800 according to the present invention, based on information related to the vehicle sensed through the sensing unit 120, the shield so that the cutoff line is generated at different locations based on the vehicle ( A portion of the plurality of pixels of 840) through which light does not pass may be set differently.

Specifically, when the information related to the sensed vehicle satisfies a first preset condition, the processor 870 may change the light transmittance of the first portion of the plurality of pixels to pass light. In addition, when the information related to the sensed vehicle satisfies a preset second condition different from the first condition, the processor 870 may change the light transmittance of the second portion different from the first portion so that light passes therethrough. .

As an example, the preset first condition may include a case in which a vehicle enters an uphill road (or a case in which the front of the vehicle body is inclined upward), as illustrated in FIG. 16A. You can. In this case, the vehicle lamp 800 according to the present invention includes a plurality of shields 840 such that the beam pattern irradiated toward the front of the vehicle is irradiated downward with respect to the vehicle (ie, the cutoff line of the beam pattern is lowered). The light transmittance of the first portion 1600a of the pixels may be changed so that light does not pass through. That is, the processor 870 may change the light transmittance so that the light does not pass based on the first condition that the preset first condition is detected in the first portion 1600a formed to pass light among the plurality of pixels.

For example, when the vehicle is in general driving, the processor 870 may control the light transmittance of the plurality of pixels such that a line corresponding to the cutoff line is in the first position 841.

Thereafter, when the preset first condition is sensed through the sensing unit 120, the processor 870 may determine to lower the cutoff line of the beam pattern output to the front. This is to provide a more optimized beam pattern to the driver by adjusting the light irradiation direction on the uphill road in the downward direction.

To this end, the processor 870 adjusts the first portion 1600a of the plurality of pixels of the shield 840 (specifically, light of the plurality of pixels) so that the cut-off line of the beam pattern descends downward. The light transmittance of the first portion 1600a may be controlled such that a region adjacent to a region controlled to pass light out of the region may pass light. Specifically, the processor 870, based on the pre-set first condition is satisfied,

In the case of FIG. 16, since light reflected from the light source unit 810 is incident on the shield 840, the shape of the region through which the light passes and the low beam pattern may be reversed. Accordingly, the larger the area through which light is not passed increases (or the area through which light passes is smaller toward the upper side, or the line 841 corresponding to the cutoff line rises upward (841a)) of the low beam pattern The cutoff line goes down.

Conversely, the preset second condition may include a case in which the vehicle enters a downhill road (or a case in which the vehicle body front is inclined toward the lower side), as illustrated in FIG. 16B. have. In this case, the vehicle lamp 800 of the present invention, the shield 840 so that the beam pattern irradiated toward the front of the vehicle is irradiated upwardly with respect to the vehicle 100 (ie, the cutoff line of the beam pattern is raised) The light transmittance of the second portion 1600b among the plurality of pixels may be changed to allow light to pass through. That is, the processor 870 controls the light transmittance of the second portion 1600b so that the second portion 1600b, which is set to pass light, passes through the light on the basis of that the preset second condition is satisfied. can do.

That is, the processor 870 may control the light transmittance of the plurality of pixels such that the line 841 corresponding to the cutoff line descends (841b).

In this case, in FIG. 16, since light reflected from the light source unit 810 is incident on the shield 840, the shape of the region through which the light passes and the low beam pattern may be reversed. Accordingly, in the cutoff line of the low beam pattern irradiated from the vehicle, the smaller the area through which light is not passed (or the larger the area through which light passes, the larger the downward area or the line 841 corresponding to the cutoff line). As it goes down (841b), it goes up.

Thereafter, when the first or second preset condition is not sensed (or released), the processor 870 sets the light transmittance of the plurality of pixels so that the line 841 corresponding to the cutoff line is restored to its original position. Can be controlled.

Through this configuration, the present invention can provide a vehicle lamp capable of changing the position of the cutoff line in an optimized manner.

In the present invention, a low beam pattern can be formed without a separate shield for generating a cutoff line by using a shield 840 in which a plurality of pixels are formed in a matrix form and independently control light transmittance. have. In addition, the present invention may implement a smart lamp by generating an optimized beam pattern according to a situation by controlling light transmittance of a plurality of pixels included in the shield 840.

Hereinafter, a vehicle lamp according to another embodiment of the present invention will be described.

17 is an exploded view for explaining a vehicle lamp according to another embodiment of the present invention, and FIGS. 18 and 19 are conceptual views for explaining the operation of the vehicle lamp shown in FIG. 17 when outputting low and high beams.

Referring to FIG. 17, a vehicle lamp 800 according to another embodiment of the present invention is located in front of a light source unit 810 including one or more light sources 822 and the light source unit 810 and has a predetermined beam pattern. A shield part including a first shield 845 to be formed and a second shield 840 that changes light transmittance so that a beam pattern is variable, a driving part 847 that drives the shield part, and the shield part and the beam when the beam pattern is changed A processor 870 that controls at least one of the driving units 847 may be included.

Specifically, the vehicle lamp 800 according to another embodiment of the present invention includes a first shield 845 forming a predetermined beam pattern in a shield part and a second shield 840 capable of changing light transmittance so that the beam pattern is variable. ) May further include a driving unit 847 formed to drive.

Descriptions of the lens 850, the first case 802, and the second case 803 are replaced with the contents described in FIG.

The shield unit including the first shield 845 and the second shield 840 may be disposed between the light source unit 810 and the lens 850. That is, the shield unit 840 may be disposed between the light source unit 810 and the lens 850 to block at least a portion of light generated by the light source unit 810 and pass the rest through the lens.

The first shield 845 may mean a shield for generating a cutoff line when the light transmittance is not variable and a low beam pattern is formed. Here, the first shield 845 is a physically fixed type shield, and is different from the second shield 840 in that light transmittance is not variable. The first shield 845 may be formed in various forms.

When the light output from the light source 822 is reflected by the reflector 830 and directed to the first shield 845, some of the light is blocked by the first shield 845. And the remaining light is not blocked by the first shield 845 and is incident on the lens 850 and then transmitted to the outside.

Through this, the present invention blocks some light by the first shield 845 and irradiates the rest of the light to the outside. Here, since the first shield 845 is a shield having a fixed shape (not deformed), the light of the same portion is always blocked, so the present invention can output a fixed beam pattern (ie, a fixed low beam pattern). have.

The second shield 840 may be the shield 840 shown in FIGS. 8 to 16. That is, the second shield 840 may include a plurality of pixels, and may be formed to independently control light transmittance for each pixel.

Also, the plurality of pixels may be arranged in a matrix format.

Each pixel may be formed to partially change the light transmittance.

The processor 870 of the present invention can independently (individually) control a plurality of pixels included in the second shield 840. In addition, the processor 870 may have a light transmittance that is partially different for each of the plurality of pixels (eg, the light transmittance of the first portion of each pixel has a first value, and the second is different from the first portion). A portion of the light transmittance may control each of the plurality of pixels (to have a second value different from the first value).

Meanwhile, the shield part of the present invention may include a rotatable body 846. The rotatable body 846 may be formed in a cylindrical rod shape.

The body 846 may be inserted into a groove provided in the second case 803, for example, and formed to be rotatable by driving of the driving unit.

The second case 803 may be provided with, for example, a groove through which the body 846 can be mounted on the left and right surfaces in a reference plane that crosses the center in the horizontal direction.

The body 846 may be inserted into the groove, and the body 846 may be disposed to cross the center of the inner space of the second case 803 in the width direction. Here, the width direction may be horizontal and vertical directions based on the front.

The rotatable body 846 may be coupled with a driving unit 847 formed to rotate the body 846 on the basis of one axis penetrating in the longitudinal direction of the body 846.

The driving unit 847, as shown in FIG. 17, a first gear 847a coupled to the body 846, a second gear 847b formed to mesh with the first gear 847a, and the first It may include an actuator (847c) coupled to the second gear (847b) is formed to rotate the second gear (847b).

17, the structure in which the first gear 847a is rotated through the second gear 847b is illustrated, but is not limited thereto. That is, the driving unit of the present invention, the actuator 847c is directly coupled to the first gear 847a may be formed to rotate the first gear 847a (ie, the second gear 847b is omitted) Can be).

The driving unit 847 may be driven by the control of the processor 870.

In addition, as illustrated in FIG. 17, the driving unit 847 may be disposed in the inner space of the second case 803, or may be disposed outside the second case 803, and the second case. It may be formed integrally with (803).

On the other hand, the shield portion, the first shield 845 is provided on one side of the rotatable body 846, the second shield 840 may be provided on the other side opposite to the one side.

For example, the first shield 845 and the second shield 840, as shown in Fig. 18 (a). The rotatable body 846 may be disposed opposite to each other. That is, the first shield 845 and the second shield 840 may be disposed to have a 180 degree phase based on the body 846. Here, one side may be, for example, the lower surface of the body 846, and the other side may be the upper surface of the body 846.

In addition, the first shield 845 and the second shield 840 may be coupled to the first rotatable body and the second body, respectively, and the first body and the second body may be integrally formed. It can be arranged on different axes. Here, being disposed on different axes may include that the first body and the second body are spaced apart and arranged in parallel.

For example, the first shield 845 may be coupled to the first body, and the second shield 840 may be coupled to the second body.

18 (b), the processor 870 may control the driving unit 847 to rotate the body 846 on which the first shield 845 and the second shield 840 are mounted. have.

As the body 846 is rotated, the first shield 845 and the second shield 840 may be rotated based on the body 846.

Accordingly, as illustrated in FIG. 18C, positions of the first shield 845 and the second shield 840 may be changed.

On the other hand, the light source unit 810 included in the vehicle lamp 800 of the present invention, as shown in Figure 19 (a), the first light source (822a) for outputting light in the upward direction, the light in the downward direction And a reflector 830 that reflects the light output from the second light source 822b and the first and second light sources 822a and 822b forward (toward the shield or toward the lens 850). You can.

As described above, the light output from the first light source 822a outputting light in the upward direction is reflected by the upper reflector (or the upper region of the first reflector or the reflector) 830a, and proceeds in the downward direction of the front side. do. Accordingly, the first light source 822a and the upper reflector may form a low beam pattern.

Conversely, the light output from the second light source 822b outputting light in the downward direction is reflected by the lower reflector (or the second reflector or the lower region of the reflector) 830b and proceeds in the upward direction. Accordingly, the second light source 822b and the lower reflector may form a high beam pattern.

In summary, the light output from the first light source 822a may be reflected by the reflector 830 (upper reflector 830a) and then form a low beam pattern through the shield.

Further, after the light output from the second light source 822b is reflected by the reflector 830 (lower reflector 830b), a high beam pattern may be formed through the shield.

At this time, the light 1 output from the first light source 822a and reflected by the upper reflector (or the upper region of the reflector) is irradiated upward (incident) with respect to the body 846 (or center) of the shield part. Can be. At this time, the irradiation direction of the light (l), as shown in Fig. 19 (a), may be in the front downward direction.

Further, the light h output from the second light source 822b and reflected by the lower reflector (or lower region of the reflector) may be radiated downward based on the body 846 (or center) of the shield. At this time, the irradiation direction of the light (h), as shown in Figure 19 (b), may be in the front upward direction.

19 (a), a front view of the vehicle lamp 800 during low beam output and a cross-sectional view taken along BB are shown, and in FIG. 19 (b), the vehicle lamp 800 during high beam output is shown. A front view and a cross-sectional view along CC are shown.

As shown in (a) of FIG. 19, the processor 870, when outputting a low beam, the first shield 845 is disposed on the lower side relative to the rotatable body 846, and the second shield The driving unit 847 may be controlled such that 840 is disposed on the upper side based on the body 846.

Accordingly, the light l output from the first light source 822a and reflected by the upper reflector 830a (or the upper region of the reflector) is capable of varying the second shield 840 (the light transmittance of the shield). Matrix shield).

When outputting a low beam, the processor 870 may control a light transmittance of at least some of the pixels included in the second shield 840 to form a low beam pattern.

Specifically, the processor 870, as shown in FIG. 11, so that a low beam pattern having a cutoff line is formed by the light 1 incident on the second shield 840, at least some of the plurality of pixels The light transmittance of (for example, some pixels forming the line 841 corresponding to the cutoff line) may be set to 0% (or less than a certain value).

In addition, the processor 870, based on information related to the vehicle sensed through the sensing unit 120, the light transmittance of at least some of the plurality of pixels included in the second shield 840 to form a variety of low beam patterns Can be controlled. The contents related to this are replaced with the contents described in FIGS. 8 to 17.

Also, as illustrated in FIG. 19A, the second light source 822b may not emit light when outputting a low beam. That is, since the light generated from the second light source 822b is light forming a high beam pattern, the processor 870 may turn off the second light source 822b when outputting a low beam.

On the other hand, the processor 870, as shown in Figure 19 (b), when outputting a high beam, the first shield 845 is disposed on the upper side of the rotatable body 846, the second shield 840 ) Can control the driving unit 847 such that the body 846 is disposed on the lower side.

 In addition, the processor 870 may turn on the first light source 822a and the second light source 822b together or output only the second light source 822b during high beam output.

During high beam output, the first shield 845 (fixed shield) is disposed on the upper side based on the body 846 (or center) of the shield portion, and is output from the first light source 822a and reflected by the upper reflector (l) A predetermined beam pattern (low beam pattern) having a cutoff line can be formed.

In addition, when outputting a high beam, the second shield 840 (matrix shield) is disposed below the body 846 (or center) of the shield, and output from the second light source 822b and reflected by the lower reflector. The light h can form various beam patterns (high beam patterns).

To this end, the processor 870, when outputting a high beam, in order to change the high beam pattern, the second shield 840 (Matrix shield) is disposed below the body 846 through which the light forming the high beam pattern passes. can do.

In addition, when outputting the high beam, the processor 870 may control the light transmittance of at least some of the plurality of pixels included in the second shield 840 to change the high beam pattern. In this regard, the contents described in FIGS. 13A to 16 can be analogously and similarly applied.

Through this configuration, when the low beam is output, the second shield 840 is disposed in a path through which the light 1 forming the low beam pattern passes, and when the high beam is output, the high beam pattern is formed. The second shield 840 may be disposed in a path through which the light h passes, thereby providing a vehicle lamp capable of forming various beam patterns.

On the other hand, in the vehicle lamp 840 of the present invention, as well as when the first shield 845 and the second shield 840 rotate or move together, the first shield 845 and the second shield 840 are independent It may be formed to be movable.

20 and 21 are conceptual diagrams for explaining another embodiment of the vehicle lamp shown in FIG. 17.

The shield portion of the present invention may be formed such that the first shield 845 and the second shield 840 are independently rotatable based on the rotatable body 846.

For example, the body 846 may include a first rotatable body and a second rotatable body. In addition, the driving unit 847 may include a first driving unit rotating the first body and a second driving unit rotating the second body.

The first shield 845 may be coupled to the first body, and the second shield 840 may be coupled to the second body.

The processor 870 may control the first driving unit of the driving unit to rotate the first shield 845, and control the second driving unit of the driving unit to rotate the second shield 840.

As shown in (a) of FIG. 20, the first shield 845 is coupled to the first body 846 and disposed on the upper side, and the second shield 840 is coupled to the second body 846a It can be formed to be rotatable relative to the second body (846a).

As shown in FIG. 20, the processor 870 controls the driving unit 847 so that the first shield 845 and the second shield 840 are superimposed on the body 846 in an upward direction. The shield can be driven.

21A illustrates a front view of a vehicle lamp 800 when outputting a low beam, and a cross-sectional view taken along D-D. Also, FIG. 21B shows a front view of the vehicle lamp 800 when outputting a high beam, and a cross-sectional view taken along E-E.

Referring to (a) of FIG. 21, in the processor 870 of the vehicle lamp according to the present invention, the first shield 845 (fixed shield) is disposed above the body 846a, and the second shield ( 840) (matrix shield) is a body 846a, the first shield 845 overlaps with the driving unit so as to be disposed on the upper side.

Through this, the light (l) output from the first light source (822a) and reflected by the upper reflector (or the upper region of the reflector), the first shield 845 and the second shield 840 is a shield portion (overlapping) That is, the shield part may be incident on the body 846a (or the upper part based on the center).

In this case, to output the low beam? The formed low beam pattern includes a cut-off line formed by the first shield 845, and at least a part of the light amount may be varied by the second shield 840 (matrix shield). .

When outputting a low beam, the driving unit 847, the processor 870, the first shield 845 and the second shield 840, the driving unit 847 so as to be disposed in the upper direction relative to the body (846a) Can be controlled.

Thereafter, a portion of the light 1 generated by the first light source 822a and reflected by the upper reflector may be blocked by the first shield 845 to form a cutoff line of a low beam pattern. In addition, the processor 870 controls the light transmittance of at least a portion of the plurality of pixels of the second shield 840, so that the amount of light passing through the second shield 840 of the reflected light (l) is Can be controlled.

At this time, the processor 870 does not need to perform control to make the light transmittance 0% (or less than a certain value) for the portion where the second shield 840 and the first shield 845 overlap. In order to form a cutoff line of a conventional low beam pattern, instead of controlling light transmittance of at least some of the plurality of pixels, the first shield 845 overlapping with the second shield 840 cutoff line of the low beam pattern To generate?

Through this, the present invention can implement various beam patterns (for example, the embodiments of FIGS. 13A to 16) by adjusting the partial light amount of the low beam pattern.

In addition, according to the present invention, the first shield 845 (fixed shield) forming a predetermined beam pattern and the second shield 846 (matrix shield or display shield) capable of changing the beam pattern are superimposed and disposed. The beam pattern can be more precisely controlled.

Also, when outputting a low beam, it is unnecessary to adjust the light transmittance (transparency) for the pixels of the second shield 840 overlapping with the first shield 845, thereby saving power consumption.

On the other hand, as shown in Figure 21 (b), when the high beam output, the processor 870, the first shield 845 overlaps the second shield 840 disposed on the upper side of the body (846a) The shield part may be controlled to be disposed on the lower side as a reference.

To this end, the processor 870 controls, for example, a second driving unit that drives a second body to which the second shield 840 is coupled, so that the second shield 840 is based on the body 846a. Can be placed on. At this time, the first shield 845 may be held above the body 846a to maintain the low beam pattern.

The light output from the second light source 822b and reflected by the lower reflector (or lower region of the reflector) enters the second shield 840 disposed below the body 846a when outputting the high beam. Can be.

The processor 870 may control the light transmittance of the second shield 840 disposed under the body 846a to vary the high beam pattern. In this regard, the contents described in FIGS. 13A to 16 may be analogously and similarly applied.

On the other hand, the vehicle lamp related to the present invention further enhances the amount of light irradiated to the low beam pattern or further enhances the amount of light irradiated to the low beam pattern, further from the vehicle lamp that can independently change the beam pattern by controlling the light transmittance independently. It is possible to provide a vehicle lamp that can.

22 is an exploded view for explaining a vehicle lamp according to another embodiment of the present invention, and FIGS. 23 and 24 are conceptual views for explaining the operation of the vehicle lamp shown in FIG. 22 when outputting low and high beams.

Referring to FIG. 22, the vehicle lamp 800 according to another embodiment of the present invention includes one or more light sources 820 (or light source units), and a first reflector 830 reflecting light generated from the light sources 820 , A shield 840 that blocks a portion of the light reflected from the first reflector 830 to form a beam pattern, and a lens 850 that projects light that has passed (or is not blocked) through the shield to the outside. You can. In addition, the vehicle lamp 800 of the present invention reflects the light reflected from the first reflector 830 back to the first reflector 830 or reflects the light generated from the light source to enter the lens 850 A second reflector 848 may be included.

The light source 820 may be formed to generate light toward an upper side, a lower side or a rear side.

The first reflector 830 reflects the light generated from the light source 820 upward, downward, or rearward (or toward the shield 840, toward the second reflector 848, or toward the lens 850). It can be formed to irradiate.

For example, the light source 822 may be disposed at the center of the interior of the first reflector 830. That is, the light source 822 may be disposed in front (the lens 850 side) based on the first reflector 830.

The shield 840 may be a mattress shield or a display shield described above.

Specifically, the shield 840 may be the shield 840 described in FIGS. 8 to 16. That is, the shield 840 may include a plurality of pixels, and may be formed to independently control light transmittance for each pixel.

Also, the plurality of pixels may be arranged in a matrix format.

Each pixel may be formed to partially change the light transmittance.

The processor 870 of the present invention can independently (individually) control a plurality of pixels included in the shield 840. In addition, the processor 870 may have a second portion different from the first portion, such that the light transmittance of the first portion of each pixel has a first value, such that the light transmittance is partially changed within one pixel. The light transmittance of can control each of the plurality of pixels (to have a second value different from the first value).

Light generated from the light source 820 and reflected by the first reflector 830 and then passed through the shield 840 (specifically, light not blocked by the shield 840) passes through the lens 850 It is possible to form a predetermined beam pattern.

The shield 840 may be disposed in front of the light source 820 and the first reflector 830 (or toward the lens 850).

Meanwhile, the present invention may include a body 846 formed to be rotatable, and the body 846 may include a second reflector 848 formed to reflect light reflected from the first reflector 830 back to the first reflector. ) May be combined.

22, the rotatable body 846 may be formed in a cylindrical rod shape.

The body 846 may be inserted into a groove provided in the second case 803, for example, and formed to be rotatable by driving of the driving unit.

The second case 803 may be provided with, for example, a groove through which the body 846 can be mounted on the left and right surfaces in a reference plane that crosses the center in the horizontal direction.

The body 846 may be inserted into the groove, and the body 846 may be disposed to cross the center of the inner space of the second case 803 in the width direction. Here, the width direction may be horizontal and vertical directions based on the front.

The rotatable body 846 may be coupled with a driving unit 847 formed to rotate the body 846 on the basis of one axis penetrating in the longitudinal direction of the body 846.

The driving unit 847, as shown in Figure 22, the first gear 847a coupled to the body 846, the second gear 847b formed to mesh with the first gear 847a, and the first It may include an actuator (847c) coupled to the second gear (847b) is formed to rotate the second gear (847b).

22, the structure in which the first gear 847a is rotated through the second gear 847b is illustrated, but is not limited thereto. That is, the driving unit of the present invention, the actuator 847c is directly coupled to the first gear 847a may be formed to rotate the first gear 847a (ie, the second gear 847b is omitted) Can be).

The driving unit 847 may be driven by the control of the processor 870.

In addition, as illustrated in FIG. 22, the driving unit 847 may be disposed in the inner space of the second case 803, or may be disposed outside the second case 803, and the second case. It may be formed integrally with (803).

The second reflector 848, for example, may be coupled to the body 846. Thereafter, the second reflector 848 may be rotated based on one axis (eg, a body 846 or an imaginary axis penetrating in the longitudinal direction of the body 846). That is, the processor 870 may control the driving unit 847 coupled to the body 846 to rotate the second reflector 848 about the one axis.

On the other hand, the shield 840 may be coupled to the upper portion of the second case 803. For example, the shield 840 may be disposed to contact the vertical surface of the body 846.

However, the shield 840 and the body 846 may not be coupled. Accordingly, even if the body 846 is rotated about one axis by the driving of the driving unit 847, the shield 840 may not be rotated.

That is, the shield 840 and the second reflector 848 may be in contact with respect to one axis (eg, the rotatable body 846). However, when the body 846 is rotated, the second reflector 848 is rotated along one axis (body 846), but the shield 840 may be fixed without being rotated.

The lens 850 may be disposed in front of the shield 840 and the second reflector 848.

Descriptions of the lens 850, the first case 802, and the second case 803 are replaced with the contents described in FIG.

That is, the vehicle lamp, at least one light source 822, spaced apart by a predetermined distance from the light source 822 is disposed at the rear, the first reflector 830 for reflecting the light generated from the light source 822 forward, A shield 840 positioned in front of the first reflector 830 and a light source 822 and a lens 850 positioned in front of the shield 840 may be included.

In addition, the second reflector 848 is provided on the lower side of the shield 840 and is formed to be rotatable based on an axis contacting the shield 840.

On the other hand, the second reflector 848 is formed to be rotatable about one axis (for example, the body 846), when outputting a low beam and outputting a high beam? Each can be placed at different locations.

Specifically, the processor 870, the body when the second reflector 848 is coupled so that the second reflector 848 is disposed at a different position when outputting a low beam and a high beam, respectively ), The driving unit 847 can be controlled.

For example, the second reflector 848 is disposed at a first position when outputting a low beam, and outputs a high beam. It may be disposed at a second location different from the first location.

For example, as illustrated in (a) of FIG. 23, the processor 870 may include the driving unit such that the second reflector 848 is disposed below the one axis (eg, the body 846). Can be controlled. In this case, when viewed from the front, the first reflector 830 may be hidden by the second reflector 848 in the lower portion of the one axis (body 846). That is, the second reflector 848 can be seen when the low beam is output from the lower portion of the uniaxial axis.

On the other hand, as shown in Figure 23 (b), the processor 870, when the high beam output, the second reflector 848 is in a horizontal position relative to one axis (for example, the body 846) The driving unit 847 can be controlled to be arranged.

In this case, when viewed from the front, as shown in FIG. 23 (c), the first reflector 830 may be seen in a lower portion of one axis (body 846). On the other hand, at least a part of the second reflector 848 may not be visible from the front side as it is disposed in a second position different from the first position during high beam output.

24 (a) shows a front view of a vehicle lamp when outputting a low beam, and a cross-sectional view taken along FF, and FIG. 24 (b) shows a front view of a vehicle lamp when outputting a high beam, GG A cross section taken along is shown.

As described above, the second reflector 848 may be disposed in the first position when outputting the low beam.

The vehicle lamp of the present invention, as shown in Figure 24 (a), may be provided with one light source (822). The light source 822 may be formed to output light to the rear.

The first reflector 830 may reflect light generated from the light source 822 toward the front. At this time, the light reflected from the upper region 830a of the first reflector 830 may be irradiated with light toward the lower side to form a low beam pattern. In addition, the light reflected from the lower region 830b of the first reflector 830 may be irradiated with light toward the upper side to form a high beam pattern.

The second reflector 848, as shown in FIG. 24 (a), outputs a low beam when the first reflector 830 (eg, a lower region 830b of the first reflector 830) It may be disposed at a first position to reflect the light reflected from the back to the first reflector 830.

That is, the first position is reflected from the first reflector 830 (specifically, the lower region 830b of the first reflector) and the light (T1) toward the lower side based on the one axis (body 846). It may refer to a position reflecting the first reflector (specifically, the upper region 830a of the first reflector).

In other words, when the low beam is output, the processor 870 reflects light reflected from the lower area 830b of the first reflector forming the high beam pattern back to the upper area 830a of the first reflector (first Position) to control the driving unit 847 such that the second reflector 848 is located.

Thereafter, light reflected back to the first reflector (specifically, light reflected back to the upper region 830a of the first reflector) may pass through the shield 840 to reinforce the low beam pattern light.

That is, the second reflector 848 is disposed on the lower side with respect to one axis (body 846), so that the light reflected from the lower area 830b of the first reflector is returned to the upper area 830a of the first reflector. By reflecting, the present invention can provide a vehicle lamp capable of reinforcing light (or light amount) forming a low beam pattern.

The processor 870 may adjust (change, control) a portion where light is reinforced in the low beam pattern by adjusting the first position of the second reflector 848.

In addition, the processor 870, by controlling the light transmittance of at least some of the plurality of pixels included in the shield 840 during low beam output, a low beam pattern including a cutoff line and various low beam patterns (FIGS. 13A to Fig. 16) can be formed.

The second reflector 848, as shown in FIG. 24, is concave to condense light reflected from the lower region 830b of the first reflector and reflect it back to the upper region 830a of the first reflector. (Or, a curved shape, a curved shape, etc.).

On the other hand, the second reflector 848, as shown in Figure 24 (b), when outputting a high beam, the light reflected from the first reflector 830 is not reflected back to the second reflector 848 In order not to be disposed in a second position different from the first position.

Specifically, when outputting a high beam, the processor 870 does not reflect light reflected from the lower region 830b of the first reflector back to the lens 850 without being reflected back by the second reflector 848. The driving unit 847 may be controlled such that the second reflector 848 is disposed at a second position different from the first position so as to be incident.

That is, the second position may be a position that does not reflect (ie does not cover) the light generated by the light source 822 and reflected by the lower region 830b of the first reflector 830.

Through such a configuration, the present invention can provide a vehicle lamp capable of outputting low and high beams using one light source.

Meanwhile, the vehicle lamp related to the present invention may include a structure capable of reinforcing a high beam as well as a low beam.

25 is a conceptual diagram illustrating another embodiment of a vehicle lamp as shown in FIG. 22.

Referring to (a) of FIG. 25, the light source (light source unit) included in the vehicle lamp may further include an auxiliary light source 824 disposed under the shield 890. The auxiliary light source 824 may be a halogen light source, LED light source, LD light source, or the like.

The shield 890 may be a shield 840 formed to change the light transmittance described above, or may be a physically fixed shield 845.

The light source 822 may be formed to irradiate light toward the first reflector 830 as described above.

In addition, the auxiliary light source 824 may be disposed spaced apart from the lower end of the shield 890, and the second reflector 848 may be disposed around the auxiliary light source 824.

The second reflector 848 may be formed to be rotated based on one axis (here, one axis is a separate body A1) or rotated at a predetermined distance from the one axis.

Fig. 25A is a sectional view when outputting a low beam, and Fig. 25B is a sectional view when outputting a high beam.

The light generated from the auxiliary light source 824, when outputting a low beam, as shown in (a) of FIG. 25, the lens 850 by the second reflector 848 disposed at the first position It can be formed to be reflected to reinforce the light of the low beam pattern.

Specifically, the auxiliary light source 824 is disposed at the bottom of the shield 890 and may be formed to irradiate light toward (or upwardly) the shield 890.

The second reflector 848, when outputting a low beam, may be disposed in a first position to reinforce the light of the low beam pattern. Here, the first position is a position to direct the light generated from the auxiliary light source 824 toward the lower end of the lens 850, for example, between the auxiliary light source 824 and the shield 890 It can be a location.

Meanwhile, the shield 890 may include at least one of light reflected from the first reflector 830 (eg, a lower portion 830b of the first reflector) or light generated from the auxiliary light source 824. It may include a passage hole (892) to be passed. In addition, the light 2500b generated by the light source 822 and reflected by the first reflector (eg, the lower region 830b of the first reflector) passes through the through hole 892 and is a high beam pattern. Can form.

At this time, a reflective member 896 may be provided in a part of the passage hole. In addition, when outputting a high beam, the second reflector 848 may be disposed at a second position different from the first position so that light generated from the auxiliary light source 824 is incident on the reflective member. In addition, the light 2500c 'generated from the auxiliary light source 824 is reflected by the reflective member 896 to reinforce the light (or the amount of light) of the high beam pattern.

That is, as shown in (b) of FIG. 25, the second reflector 848 is disposed at the second position when outputting the high beam, so that the first reflector (specifically (the lower region of the first reflector ( 830b)), the light 2500b directed to the through hole 892 may be unblocked.

For example, the second position in which the second reflector 848 is positioned when outputting a high beam, the light generated from the light source 822 is reflected in the lower region 830b of the reflector, and the pass hole 892 of the shield 890 Heading towards means the unblocked position. In addition, the second position in which the second reflector 848 is positioned during high beam output is at a position where light generated from the auxiliary light source 824 is not reflected by the second reflector 848 (or the auxiliary light source 824). It may mean a position that does not block the generated light is directed to the shield (890).

To this end, the processor 870, when outputting a low beam, positions the second reflector 848 in a first position, and when outputting a high beam, the second position in a second position different from the first position. The driver 847 may be controlled such that the reflector 848 is located.

At this time, the second reflector 848, is coupled to a separate body (A1), may be rotated or rotated based on one axis passing through the longitudinal direction of the body (A1).

The auxiliary light source can be individually turned on / off during high beam output. That is, when outputting a high beam, the processor 870 may turn on or off the auxiliary light source 824.

The driving unit 847 may be formed to drive the separate body A1.

Meanwhile, when outputting a low beam, the second reflector 848 is disposed at a first position, as shown in FIG. 25 (a), and the first reflector 830 (specifically, the first reflector) After being reflected from the lower region 830b), light 2500b directed to the through hole 892 may be blocked.

In view of this, the second reflector 830 may be understood to perform the role of the reflector and the role of the shield.

To this end, one surface of the second reflector 848 (for example, a surface facing a light source (or auxiliary light source)) is formed of a reflective member, and the other surface opposite to one surface of the second reflector 848 is a reflective member May not be formed.

In the structure of FIG. 25, a cutoff line of a low beam pattern may be formed by the end portion 894 of the shield 890. That is, the end portion 894 of the shield 890 may mean a portion opposite to a portion provided with the reflective member 894 of the through hole 892. A portion of the reflected light generated by the light source 822 by the upper region 830a of the first reflector is blocked by the end portion 894 of the shield 890, and the remaining portion passes through the shield 890. Therefore, it is incident on the lens 850. Through this configuration, the present invention can form a low beam pattern.

In summary, the vehicle lamp of the present invention, as shown in Figure 25 (a), when outputting a low beam, to directly reflect the light generated from the auxiliary light source 824 to the lower end of the lens 850 The second reflector 848 can be disposed in the first position. Through this, the present invention can reinforce the light (light amount) of the low beam pattern using light generated from the auxiliary light source.

In addition, as the second reflector 848 is disposed at the first position, the light generated by the light source 822 and reflected by the lower region 830b of the first reflector (light forming a high beam pattern) may be 2 It is blocked by the reflector 848, so that it cannot be directed to the pass hole 892 of the shield 890. Through this, the present invention can prevent the formation of a high beam pattern during low beam output.

In addition, as the second reflector 848 is disposed in the first position, the light generated from the auxiliary light source 824 passes through the hole 892 and the reflection of the shield 890 located above the auxiliary light source 824. It does not face the member 896, and thus does not form a high beam pattern.

In addition, the vehicle lamp of the present invention, when outputting a high beam as shown in Figure 25 (b), the light generated from the auxiliary light source 824 is a pass hole 892 and a reflecting member of the shield 890 immediately The second reflector 848 may be disposed at the second position to be irradiated to 896.

 Further, as the second reflector 848 is disposed at the second position, light generated by the light source 822 and reflected by the lower region 830b of the first reflector is blocked by the second reflector 848. Instead, the high beam pattern may be formed by passing through the pass hole 892 of the shield 890.

Further, as the second reflector 848 is disposed at the second position, the light generated from the auxiliary light source 824 is not reflected directly to the lens 850 by the second reflector 848, and the shield ( The light (light amount) of the high beam pattern may be reinforced by the reflection by the reflective member 896 formed in the pass hole 892 of 890.

26 and 27 are conceptual views for explaining another embodiment of the vehicle lamp shown in FIG. 22.

26A is a cross-sectional view of a vehicle lamp when outputting a low beam, and FIG. 26B is a cross-sectional view of a vehicle lamp when outputting a high beam.

Referring to (a) of FIG. 26, a light source 820 of a vehicle lamp according to another embodiment of the present invention includes a first light source 822a outputting light to the upper side and a second light source outputting light to the lower side 822b and an auxiliary light source 824 disposed under the shield 890. The shield 890 may include a passage hole 892 through which the light generated by the second light source 822b and reflected by the first reflector (specifically, the lower region 830b of the first reflector) passes through. have.

The second light source 822b may emit light when outputting a low beam and emit light when outputting a high beam. That is, since the processor 870 forms the high beam pattern of the light generated by the second light source 822b, when outputting the low beam, the second light source 822b may be turned off (not emitted).

On the other hand, when outputting a high beam, the processor 870 may emit (turn on) the second light source 822b.

The processor 870 may emit (on) both the first light source 822a when outputting a low beam and when outputting a high beam, and when outputting a high beam, turn off the first light source 822a. You can also

On the other hand, the second reflector 848, when outputting a low beam, may be disposed in a first position to reflect the light generated from the auxiliary light source 824 to directly enter the lower end of the lens 850.

In addition, the second reflector 848, as shown in Figure 26 (b), when outputting a high beam, the light generated from the auxiliary light source 824 and the second light source (822b) is generated The light 2600c reflected by the 1 reflector (specifically, the lower region 830b of the first reflector) may be disposed at the second position to face the shield 890.

Further, the light 2600c generated by the second light source 822b and reflected by the first reflector (specifically, the lower region 830b of the first reflector 830) passes through the shield 890 through hole ( 892) to form a high beam pattern.

As described above, a reflective member 896 may be provided in a partial region of the through hole 892.

Light generated from the auxiliary light source 824 may be reflected by the reflective member to reinforce the light of the high beam pattern.

To this end, when the high beam is output, the processor 870 is generated by the second light source 822b and reflected by the lower region 830b of the first reflector, as shown in FIG. The light 2600c directed to the passage hole 892 of the 890 and the light generated from the auxiliary light source 824 are directed to the reflective member provided in a partial area (or part) of the passage hole 892 of the shield 890 Thus, the second reflector 848 can be placed in the second position.

At this time, the second reflector of the present invention, as shown in Figure 26, is coupled to one axis (for example, an additional body) is rotated relative to the one axis (A1), or as shown in Figure 27 Likewise, spaced apart by a predetermined distance from the one axis (for example, an additional body), it may be formed to be rotatable relative to the one axis (A1).

As illustrated in FIG. 27, even when the second reflector 848 is formed to be rotated by being spaced apart by a predetermined distance relative to one axis A2, the processor 870, when outputting a low beam, uses an auxiliary light source. To reflect the generated light directly to the lower end of the lens (and / or to block the light generated by the second light source and reflected by the lower region 830b of the first reflector toward the passage hole of the shield 890) ) May be disposed in a first position.

In addition, when outputting the high beam, the processor 870 directs light generated from the auxiliary light source toward the pass hole 892 and the reflection member 896 of the shield 890 (and / or is generated by the second light source) The second reflector 848 may be disposed at a second position different from the first position so that the light is reflected by the lower region of the first reflector and faces the through hole of the shield.

28 is a conceptual diagram illustrating an embodiment in which a vehicle lamp related to the present invention is applied.

The vehicle lamp related to the present invention can output (illuminate, generate) light forward to form a predetermined beam pattern. At this time, the processor 870, when a predetermined object is detected to irradiate light through the sensing unit 120 of the vehicle, the shield 840 so that light is irradiated to the detected object using the vehicle lamp 800 Can be controlled.

Here, the preset object means an object preset in order to additionally (or intensively) irradiate light in ADAS, for example, an object existing within a certain distance based on the vehicle 100 (for example, , Other vehicles, people, animals, signs, surroundings, notice boards, traffic lights, lanes, etc.), or objects configured to alert the driver. The preset object may be determined or changed based on a processor control or user setting.

In this case, the processor 870 may control light transmittance of at least some of the plurality of pixels included in the shield 840 so that light is irradiated to the sensed object, based on the size and position of the sensed object. have.

In addition, the processor 870 of the vehicle lamp of the present invention, when another vehicle (that is, the vehicle opposite) that is traveling in a direction opposite to the direction in which the vehicle 100 is traveling is detected, light is irradiated to the other vehicle To prevent this, the light transmittance of the shield 840 can be controlled.

To this end, when the other vehicle traveling in the opposite direction is detected, the processor 870 passes the light irradiated to the corresponding area so that light passing through the reflector (the first reflector) is not irradiated toward the detected other vehicle. The light transmittance of the pixel can be reduced.

Through this configuration, the vehicle lamp of the present invention can implement the Antiglare High-beam Assist function that prevents light from being irradiated to the vehicle opposite.

The vehicle related to the present invention may include the vehicle lamp 800 described above. That is, the vehicle lamp 800 described above may be included in the vehicle 100.
