However, the heat dissipation unit 131 is just an example to help understanding of the present invention. The installation direction of can be changed in various ways depending on the heat dissipation efficiency or structure.

The heat dissipation unit 131 may be formed of a heat sink composed of a plurality of heat dissipation fins, and a fan (not shown) may be installed to cool the heat generated from the heat sink more quickly as necessary.

Light generated from the light source unit 110 may be reflected by the reflector 120 toward the front of the vehicle, and a lens (not shown) irradiating the light reflected by the reflector 120 to the outside of the vehicle in front of the reflector 120. ) Can be installed.

At this time, in the embodiment of the present invention, the light source unit 110 includes a first light source unit 112 and a second light source unit 113 including a plurality of light sources arranged in different directions, and the reflector 120 includes a first light source unit ( 112 and the case where the second light source unit 113 is used in common will be described by way of example. Detailed descriptions of the first light source unit 112, the second light source unit 113, and the reflector 120 will be described later. Shall be.

2 is a perspective view illustrating a light source unit according to an exemplary embodiment of the present invention, and FIG. 2 is an example in which the light source unit 110 of FIG. 1 described above is shown in an opposite direction for convenience of description. In addition, although the plurality of light source units 110 are present in FIG. 1, the light source units of FIG. 2 are identical to the plurality of light source units 110 of FIG. Can be applied.

Referring to FIG. 2, the light source unit 110 according to the embodiment of the present invention includes a substrate 111, a first light source unit 112 including a plurality of light sources 112a and 112b arranged in a first direction, and a second direction. And a second light source unit 113 including a plurality of light sources 113a, 113b, and 113c arranged. In an embodiment of the present invention, a first direction is a driving direction of a vehicle, and a second direction is a driving direction of the vehicle. For example, a case in which the direction is perpendicular to is described as an example. However, this is only an example to help understanding of the present invention, and the first and second directions for performing two or more functions may be used depending on the use and need. It can be changed in various ways.

The substrate 111 may be a printed circuit board on which a plurality of light sources 112a, 112b, 113a, 113b, and 113c included in the first light source unit 112 and the second light source unit 113 are installed, respectively. In the example, a case where all of the plurality of light sources 112a, 112b, 113a, 113b, and 113c included in the first light source unit 112 and the second light source unit 113 are respectively installed on one printed circuit board will be described. However, this is merely an example to help understanding of the present invention, and the present invention is not limited thereto, and a printed circuit board may be used separately for each light source.

In the exemplary embodiment of the present invention, a light emitting diode (LED) is used as the plurality of light sources 112a, 112b, 113a, 113b, and 113c respectively included in the first light source unit 112 and the second light source unit 113. Although a case will be described by way of example, this is merely an example to help the understanding of the present invention, and various kinds of light sources may be used without being limited thereto.

In the first light source unit 112, a plurality of light sources 112a and 112b may be arranged in a driving direction of the vehicle, and the second light source unit 113 may include a plurality of light sources 113a, in a direction perpendicular to the first light source unit 112. 113b and 113c may be arranged.

In this case, the first light source 112 and the second light source 113 are arranged in different directions so that the first light source 112 and the second light source 113 differ from each other even when the reflector 120 is commonly used. In order to have a focus, it is possible to perform different functions, for example, a daytime running lamp function or a fog lamp function.

For reference, daytime running lights are lit when the ignition key switch is "on" in North America and some parts of Europe, even during daylight, when the driver's vision is insufficient due to fog, rain, or yellow dust. This is to make it easier for pedestrians and pedestrians to recognize their vehicles. The fog lights are used to secure the driver's vision in bad weather conditions such as snow, rain, and fog. It surveys nearby places but is widely surveyed to facilitate identification on opposing vehicles and to verify the presence of pedestrians or other vehicles.

At this time, the embodiment of the present invention refers to the daytime running light or the fog light as an example of the function performed by the first light source 112 and the second light source 113, this is an example to help the understanding of the present invention This is only an example, and may also function as a high beam or a low beam.

For reference, while the high beams secure the driver's field of vision to a relatively long distance in front of the vehicle, they can safely drive even at night, while the high beams can cause glare to the driver of the opposing vehicle or the preceding vehicle. While glare may be prevented from being caused to the driver of the vehicle, there is a side in which the driver's visibility is weaker than that of the high beam.

In the embodiment of the present invention, a plurality of light sources 112a and 112b included in the first light source unit 112 are arranged in the driving direction of the vehicle, and will be described with an example of performing a function such as a daytime running light or an uplight. The plurality of light sources 113a, 113b, and 113c included in the second light source unit 113 may be arranged in a direction perpendicular to the first light source unit 112, that is, in a direction perpendicular to the driving direction of the vehicle. An example of performing the function of will be described.

In other words, in the embodiment of the present invention, by arranging a plurality of light sources 112a, 112b, 113a, 113b, and 113c included in the first light source 112 and the second light source 113 in different directions, Even when using the reflector 120 will be able to perform a variety of functions.

Meanwhile, in FIG. 2, the plurality of light sources 112a and 112b included in the first light source unit 112 are discontinuously arranged and the plurality of light sources 113a, 113b and 113c included in the second light source unit 113. It can be seen that is arranged continuously, which is merely an example to help understanding of the present invention, without being limited to this, any one of the first light source 112 and the second light source 113 is continuously arranged and the rest One may be arranged discontinuously, and a light source positioned at a point where the first light source unit 112 and the second light source unit 113 intersect, for example, in FIG. 2, the light source 113b of the second light source unit 113 may be formed. The first light source unit 112 and the second light source unit 113 may be used in common. That is, the light source 113b positioned at the point where the first light source unit 112 and the second light source unit 113 intersect may be used when the light irradiation pattern is formed by the first light source unit 112, and the second light source unit 113 may be used. It can also be used when forming a light irradiation pattern by.

Hereinafter, an arrangement pattern of a plurality of light sources included in each of the first light source unit 112 and the second light source unit 113 according to an embodiment of the present invention will be described.

3 to 5 are schematic diagrams illustrating a first light source unit and a second light source unit according to an embodiment of the present invention, and showing an arrangement pattern for a plurality of light sources included in the first light source unit and the second light source unit. . In this case, reference numerals are used in the order of 112a, 112b, 112c, ... for the plurality of light sources included in the first light source unit 112 in FIGS. 3 to 5, and included in the second light source unit 113. For a plurality of light sources, reference numerals are used in the order of 113a, 113b, 113c, ...

3 to 5 illustrate an arrangement pattern of a plurality of light sources included in each of the first and second light sources 112 and 113, and the plurality of light sources illustrated in FIGS. 3 and 5. In addition, additional light sources may be formed having a similar pattern.

Referring to FIG. 3, unlike the above-described FIG. 2, the plurality of light sources 112a, 112b, and 112c included in the first light source unit 112 are continuously arranged and the plurality of light sources 113a included in the second light source unit 113. , 113b) can be seen discontinuously arranged. That is, the plurality of light sources 113a and 113b included in the second light source unit 113 may be arranged at both sides with respect to the first light source unit 112.

4, the plurality of light sources 112a and 112b included in the first light source unit 112 are discontinuously arranged, and the plurality of light sources 113a and 113b included in the second light source unit 113 are continuously arranged. The plurality of light sources 112a and 112b included in the first light source unit 112 may be arranged to overlap a portion of the two light sources 113a and 113b included in the second light source unit 113.

Referring to FIG. 5, in contrast to FIG. 4 described above, the plurality of light sources 112a and 112b included in the first light source unit 112 are continuously arranged and the plurality of light sources 113a and 113b included in the second light source unit 113. ) Are discontinuously arranged, and the plurality of light sources 113a and 113b included in the second light source unit 113 are arranged to partially overlap with the two light sources 112a and 112b included in the first light source unit 112. It can be seen that.

The arrangement pattern of the plurality of light sources included in the first light source unit 112 and the second light source unit 113 shown in FIG. 3 to FIG. 5 is just an example for better understanding of the present invention. Instead, the first light source unit 112 and the second light source unit 113 may be arranged in various patterns under conditions that maintain the arrangement direction, that is, the first direction and the second direction.

FIG. 6 is a schematic view illustrating a light irradiation direction of a vehicle lamp according to an exemplary embodiment of the present invention. In FIG. 6, an arrangement pattern of the first light source unit and the second light source unit is described as an example of the arrangement pattern of FIG. 2. Let's do it.

Referring to FIG. 6, a light source 113a included in the second light source unit 113 is arranged in a direction perpendicular to the driving direction of the vehicle, and the first light source 113a is disposed on both sides of the second light source unit 113 in the driving direction of the vehicle. It can be seen that a plurality of light sources 112a and 112b included in the light source unit 112 are arranged. 6, only one light source 113a of the plurality of light sources 113a, 113b, and 113c included in the second light source unit 113 is illustrated, and the others 113b and 113c are not shown. It can be understood that they are arranged in a direction perpendicular to the direction.

At this time, since the second light source unit 113 is arranged in a direction perpendicular to the traveling direction of the vehicle, when the light is reflected by the reflector 120 and irradiated to the front of the vehicle, the second light source unit 113 may be irradiated and irradiated to a wide area where the front of the vehicle is near. Since the first light source 112 is arranged in the driving direction of the vehicle, when the light is reflected by the reflector 120 and irradiated to the front of the vehicle, the first light source 112 is irradiated to a farther distance than the second light source 113 to secure a far field of view. Becomes possible.

In this case, the light irradiation pattern by the second light source unit 113 may be irradiated with respect to the downward direction based on the cutoff line L as shown in FIG. 7, and the light irradiation pattern by the first light source unit 112 is illustrated in FIG. 7. As shown in FIG. 8, light may be irradiated to both the upper and lower sides of the cutoff line L. FIG.

Accordingly, in the present invention, by arranging the first light source 112 and the second light source 113 in different directions to have different focus, the reflector 120 is used in common, but two or more functions, for example, daytime driving It is possible to implement the functions of the back light, fog light, high light and low light.

In this case, as described above, the first light source unit 112 and the second light source unit 113 to implement a different light irradiation pattern is only an example for the understanding of the present invention, the first light source unit 112 And at least one light source included in at least one of the first light source part 112 and the second light source part 113 when a light quantity is not secured after forming the light irradiation pattern through at least one of the second light source parts 113. The amount of light may be supplemented by adjusting the amount of light, and when sufficient amount of light is secured by a light irradiation pattern formed through at least one of the first light source 112 and the second light source 113, the amount of light may be supplemented as described above. The process can be omitted.

In this case, adjusting the amount of light in the embodiment of the present invention may include controlling the brightness of the light source by turning on, turning off the light, and controlling current, and the like. It can be understood that the above can be used.

For example, when the light irradiation pattern is formed through the first light source unit 112, if a sufficient amount of light is not secured, the current supplied to the plurality of light sources included in the first light source unit 112 is increased or the second light source unit ( By supplying a current to at least one of the plurality of light sources 113a included in 113 and additionally lighting it, it is possible to compensate for the insufficient light amount.

In addition, when a light irradiation pattern is formed through a combination of one or more light sources included in each of the first light source unit 112 and the second light source unit 113, the first light source unit 112 and the second light source may not be secured. The amount of light may be supplemented by increasing the amount of current supplied to the light source already lit to form a light irradiation pattern in the light source unit 113 to increase the amount of light or by additionally supplying a current to the non-lit source.

At this time, whether or not enough light is secured can be confirmed by a light distribution performance test, etc. at the time of manufacturing a lamp by a manufacturer, and in this case, when it is confirmed that sufficient light is not irradiated to satisfy the legal light distribution, the light source already turned on It may be set in advance to increase the current supplied to the light source or to turn on the light source in addition, and the driver may operate a control device such as a switch installed in the vehicle while the light is irradiated according to a predetermined light irradiation pattern. The amount of light can be supplemented by increasing the current supplied or by lighting additional light sources.

In addition, as described above, it may be set in advance by the manufacturer to supplement the amount of light, but the present invention is not limited thereto. When the amount of light irradiated according to the light irradiation pattern while the vehicle is running is detected by a sensor installed in the vehicle, a sufficient amount of light is sufficient. The current supplied may be increased or the additional light source may be turned on until it is detected as secured.

On the other hand, the vehicle lamp according to an embodiment of the present invention determines the light irradiation pattern according to the driving environment of the vehicle, a plurality of light sources included in the first light source 112 and the second light source 113 according to the determined result Forming a light irradiation pattern through one or more of the lighting or light quantity control of the, and may further include a control unit 140 for controlling the amount of light supplements based on the manufacturer's settings or sensors installed in the vehicle, the control unit 140 Same as FIG. 9.

Referring to FIG. 9, the controller 140 according to the embodiment of the present invention may include a detector 141, a determiner 142, and a driver 143.

The detector 141 may detect a driving environment of the vehicle, for example, vehicle speed, illumination, presence of a front vehicle (for example, an opposing vehicle or a preceding vehicle, etc.), road characteristics, road surface conditions, lane directions, and weather conditions. Various sensors may be included.

That is, according to the detection result of the detection unit 131, as described above, the light can be irradiated with various light irradiation patterns such as daytime running light, fog light, upward light and downlight. In addition, the detector 141 may also include a sensor for detecting the amount of light irradiated to the front of the vehicle in order to determine whether the amount of light as described above.

Sensors included in the sensing unit 141 may be added, changed, or omitted according to a sensing target, and the sensing unit 141 may be omitted when the driver directly determines the light irradiation pattern.

The determination unit 142 may determine the light irradiation pattern according to the detection result of the sensing unit 141 or the driver's operation, and may determine the light source unit or the light source to be driven according to the determined light irradiation pattern. For example, the determination unit 142 determines the light irradiation pattern for the daytime running light, the fog light, the upward light and the downlight as described above, and according to the determination result, the first light source unit 112 and the second light source unit 113. It is possible to determine whether to drive or whether to drive a plurality of light sources included in the first light source 112 and the second light source 113, respectively.

That is, the determination unit 142 determines a light source unit (eg, one or more light source units of the first light source unit 112 and the second light source unit 113) to be driven according to the driving environment of the vehicle, and includes the determined light source unit. Through the process of determining the light source to be driven among the plurality of light sources to be able to form a suitable light irradiation pattern according to the driving environment of the vehicle.

For example, when the front vehicle does not exist, the determination unit 142 may supply current to all light sources included in the first light source unit 112 and the second light source unit 112, and when the front vehicle exists. The amount of light may be reduced by turning off one or more light sources included in the first light source unit 112 or by reducing a current supplied thereto.

In addition, the determination unit 142 may supply current to all the light sources included in the light source unit 112 and the second light source unit 112 or only the light source included in the first light source unit 112 during night driving. When the road surface is wet due to bad weather, in order to prevent glare of the opposite vehicle by the light reflected on the road surface, the light source irradiating the light directly in front of the vehicle is turned off or the current is reduced to reduce the amount of light. In the case of FIG. 6, the light source which is turned off or reduced in bad weather may be a light source 112b which is located at the innermost side from the front of the vehicle among light sources included in the first light source unit 112.

The driver 143 may supply a current to the light source unit or the light source to be driven according to the determination result of the determination unit 142. At this time, the intensity of the current supplied by the driver 143 may be adjusted according to the amount of light.

On the other hand, the driving unit 143 increases the current supplied to the light source unit or the light source that is already driven when the driver operates the switch installed in the vehicle according to the manufacturer's setting, or the light source unit or light source that is not lit when forming the light irradiation pattern If the light source is additionally turned on by supplying a current, or the sensing unit 141 determines that the amount of light is not sufficient, the driving unit 143 increases the amount of current supplied to the light source unit or the light source that is already driven. A sufficient amount of light can be ensured by increasing the amount of light or by additionally lighting the light source by supplying a current to the unlit light source or the light source when forming the light irradiation pattern.

In this case, the light source unit or the light source to be added may be a light source unit or a light source that is not used in the already formed light irradiation pattern, or may be a light source separately installed to supplement the amount of light.

10 is a flowchart illustrating a control method of a vehicle lamp according to an embodiment of the present invention.

As shown, the vehicle lamp control method according to an embodiment of the present invention, first to determine the detection result of the sensing unit 141 or the light irradiation pattern according to the driver's operation (S110). That is, the determination unit 142 determines the appropriate light irradiation pattern among the above-mentioned light irradiation patterns such as the daytime running light, the fog light, the upward light and the downlight according to the detection result of the detection unit 141 or the driver's operation. .

The light source unit or the light source to be driven is determined based on the detection result of the sensing unit 141 or the light irradiation pattern according to the driver's operation (S120). That is, the determination unit 142 includes a plurality of light sources arranged in a first direction 112 with a plurality of light sources arranged in a first direction (the driving direction of the vehicle) and a plurality of light sources in a second direction (a direction perpendicular to the driving direction of the vehicle). The light source unit or the light source to be driven is determined from the second light source unit 113.

At this time, in the exemplary embodiment of the present invention, a light irradiation pattern according to a vehicle driving environment may be formed through at least one light source included in one of the first light source unit 112 and the second light source unit 113. One or more of the plurality of light sources included in the light source unit 112 and one or more of the plurality of light sources included in the second light source unit 113 may be combined to form a light irradiation pattern, but is not limited thereto.

If it is determined that the light source unit or the light source to be driven according to the light irradiation pattern, the current is supplied to the light source unit or the light source by the driver 143 (S130).

When it is determined that the amount of light is insufficient in the state that the light is irradiated by the above-described step S130 (S140), to increase the current supplied to the light source unit or the light source that is already driven or to supply the current to the additional light source to supplement the light amount (S150).

In this case, when it is determined that sufficient light amount is secured in the above-described step S130, the above-described steps S140 and S150 may be omitted.
