Description

Lamp for vehicle

More particularly, the present invention relates to a lamp for a vehicle, and more particularly, to a lamp having a predetermined length and a lens having a predetermined length for emitting light generated from the linear light source module to the outside, To a vehicle lamp.

Generally, the vehicle is equipped with various kinds of lamps having a lighting function for easily confirming an object located in the vicinity of the vehicle at nighttime driving, and a signal function for notifying other vehicle or road users of the running state of the vehicle.

For example, a head lamp and a fog lamp mainly for lighting function, a turn signal lamp, a tail lamp, a brake lamp, A brake marker, a side marker, and the like. Such a vehicle lamp is regulated by the regulations on installation standards and specifications so that each function can be fully exercised.

These lamps emit light to the outside as the light emitted from the light source is irradiated forward, thereby providing discriminating power to the driver at night or providing discrimination power to other driver or pedestrians as they emit light.

Bulbs are mainly used as light sources for these lamps, but light emitting diodes (LEDs) having a long lifetime and excellent lighting performance have been recently applied.

However, since the light generated in the case of the LED is irradiated with a direct-light type, the light is irradiated with a strong light on the front side while the light is irradiated with a weak light on the hot spot, There is a disadvantage in that this occurs.

Also, as mentioned above, LEDs should be arranged at a minimum spacing in accordance with the narrow range of light irradiation while having excellent brightness, and the number of lenses corresponding to a plurality of LEDs arranged at a minimum interval must be arranged There is a disadvantage in that the manufacturing cost is increased due to an increase in the number of LEDs, which are expensive parts.

Particularly, since a plurality of LEDs and a lens corresponding to the plurality of LEDs are disposed, respectively, the emitted light image is formed in a dot shape, which has a disadvantage that satisfaction with the appearance design is not high.

As the plurality of light sources 210 constituting the linear light source module 200, the color temperature is about 5500K, which is close to the sunlight, which minimizes the fatigue of the eyes of the human eye and minimizes the size, A light emitting diode (LED), which is a semiconductor light emitting element having economical efficiency due to its semi-permanent lifetime, can be applied, and a plurality of LEDs emitting light of the same or different colors can be applied according to the required light amount or use.

In the vehicle lamp 100 according to the first embodiment of the present invention, the light source 210 is an LED. However, in some cases, various types of light sources 210 such as a bulb, a laser, ) May be applied.

The substrate 220 may be electrically connected to the light source 210 and may support the light source 210. In addition, the substrate 220 has a plurality of circuits formed on the substrate surface, and can receive a current from the outside and a signal as to whether the light source 210 is on or off from the controller.

The substrate 220 has a bar shape having a predetermined length and a plurality of light sources 210 may be disposed on one surface of the substrate 220 with a predetermined gap therebetween, The light source module including the light source 210 and the substrate 220 may be a line light source module 200 constituting one line.

The lamp 100 for a vehicle according to the first embodiment of the present invention may include a lens 300 having a predetermined length for emitting light emitted from the linear light source module 200 to the outside.

The lens 300 may be formed to have a length corresponding to the length of the substrate 220.

The lens 300 may be recessed inwardly to accommodate the linear light source module 200 in the central region of the bottom.

A first incident surface 310 forming a convex surface toward the light source 210 is formed in a direction parallel to the optical axis while the linear light source module 200 is disposed in the accommodation space of the lens 300, A second incident surface 320 and a third incident surface 330 extending in a direction intersecting the first incident surface 310 are formed on both sides of the incident surface 310 to surround the light source 210 .

Accordingly, the first incident surface 310 is formed in a direction parallel to the optical axis in a state where the linear light source module 200 is disposed in the accommodation space of the lens 300, And the second incident surface 320 and the third incident surface 330 are formed on both side regions of the linear light source module 200 so that light generated in the lateral direction of the linear light source module 200 .

A flat exit surface 340 may be formed at a predetermined distance from the first incident surface 310. The left and right spacing of the exit surface 340 may be equal to the width of the first incident surface 310, It can be formed wider than the gap.

The first reflection surface 322 and the second reflection surface 332 may be formed to be inclined at regular intervals from the second incident surface 320 and the third incident surface 330.

Since the second incident surface 320 and the third incident surface 330 are formed in parallel to each other in the direction intersecting the opposite ends of the first incident surface 310, The spacing of the planes 330 may correspond approximately to the spacing of the first incident planes 310.

The first reflecting surface 322 and the second reflecting surface 332 are formed on both sides of the emitting surface 340. The first reflecting surface 322 and the second reflecting surface 332 are formed on both sides of the emitting surface 340. [ The second incident surface 320 and the third incident surface 330 may be inclined with respect to each other.

That is, the first reflection surface 322 formed at the position corresponding to the second incident surface 320 is inclined in a direction from one end of the second incident surface 320 toward one end of the exit surface 340, The second reflective surface 332 formed at the position corresponding to the third incident surface 330 also tilts in the direction from the end of the third incident surface 330 toward the other end of the exit surface 340, The first reflecting surface 322 and the second reflecting surface 332 form opposite sides of the lens 300 so as to face each other.

Therefore, the lens 300 can be formed in a shape having a cross-sectional shape close to an approximately hemispherical shape as shown in Fig.

For reference, the first reflective surface 322 and the second reflective surface 332 of the lens 300 may be deposited with a metal such as aluminum, aluminum alloy, chrome, or chromium alloy to form a reflective layer.

Accordingly, the light generated from the linear light source module 200 is irradiated to the outside through the exit surface 340 of the lens 300 having the above-described configuration, A surface emitting image can be realized.

≪ Embodiment 2 >

FIG. 5 is a bottom perspective view of a vehicle lamp according to a second embodiment of the present invention, FIG. 6 is a longitudinal sectional view of FIG. 5, Fig. 3 is a view schematically showing a light output path in a state where a vehicle lamp according to the embodiment is mounted on a vehicle.

The lamp 100 for a vehicle according to the second embodiment of the present invention is different from the lamp 100 for a vehicle according to the first embodiment described above in that a plurality of optics 350 The same reference numerals are assigned to the same parts and the repeated description thereof will be omitted.

5 and 6, a first incident surface 310 of the lens 300 is provided with a first optic surface 352 inclined at a predetermined angle in the first direction and a second optic surface 352 inclined from the first optic surface 352 And the second optic surface 354 formed at an angle to the second direction by a predetermined angle are formed at regular intervals.

6, the optic 350 includes a first optic surface 352 inclined at a small angle toward the first direction with respect to the first incident surface 310, The first optic surface 352 may include a second optic surface 354 that is inclined at an angle greater than the tilt angle of the first optic surface 352, Can be formed larger than the area.

In this case, since the second optic surface 354 is not a section through which light is substantially transmitted, it may be formed at right angles to the first incident surface 310. However, when the lens is injection molded using a mold, It is preferable that the second optical surface 354 is inclined at a large angle with respect to the first optical surface 352 because there is a risk that a mold lack may occur when the second optical surface 354 is at right angles.

Herein, the inflection point 356 of the first optic surface 352 and the second optic surface 354 in one of the optic 350 and the first optic surface 352 in the adjacent one of the optic 350, It is preferable that the interval between the second optical surface 354 and the inflection point 356 is designed to be approximately 10 mm or less for uniformity of brightness and light control.

This is because when the distance between the inflection points 356 of the optics 350 is designed to be 10 mm or more, since the size of the optics 350 disposed on the first incident surface 310 is relatively large, The image of the optic may be exposed from the outside as it is, and the optic may be unfavorably bad. In addition, light may be intensively transmitted to either one of the optics, and the light distribution quality may be deteriorated due to unevenness of brightness .

However, when the spacing between the inflection points 356 of the optics 350 is designed to be within 10 mm as in the embodiment of the present invention, the size of each optic is small as the optics are densely arranged, When viewed from the outside of the city, it is seen as a single line so that the aesthetics are not hindered, and the light is not transmitted intensively to either one of the optics, thereby improving the light distribution quality according to the uniformity of luminance.

In addition, it is preferable that the angle of the first optic surface 352 and the second optic surface 354 of the optic 350 is an obtuse angle, and the angle of the obtuse angle is preferably 170 degrees or less.

The reason for this is to secure a sufficient area for the first optic surface 352 of the optic 350 through which the light incident through the first incident surface 310 is transmitted.

In other words, if the angle is designed to be 170 degrees or more, the area of the second optic surface 354, which is not transparent to light, is inevitably widened, and accordingly, the area of the first optic surface 356 can be reduced .

The first optical surface 352 is formed to have a larger sectional area than the second optical surface 354 so that the light incident through the first incident surface 310 of the lens 300 is optically 350 by the first optic surface 352 of the second optical system.

At this time, the light incident through the first incident surface 310 of the lens 300 may be refracted in the direction opposite to the oblique direction of the first optic surface 352 of the optic 350 and may be irradiated to the outside.

The light irradiation path of the vehicle lamp 100 having the above configuration will be described with reference to FIGS. 4 and 6. FIG.

In the case of the vehicle lamp 100 according to the second embodiment of the present invention, the configuration other than the optic 350 formed on the first incident surface 310 of the lens 300, as described above, The path of the light emitted from the linear light source module 200 will be described with reference to FIG. 4 once again supporting the first embodiment.

4, part of the light emitted from the light source 210 of the linear light source module 200 is incident through the first incident surface 310 having a convex shape toward the accommodation space, 340). ≪ / RTI >

Part of the light emitted from the light source 210 of the linear light source module 200 is incident through the second incident surface 320 and is reflected by the first reflection surface 322, Can be irradiated to the outside through one side region of the light emitting diode (340).

Part of the light emitted from the light source 210 of the linear light source module 200 is incident through the third incident surface 330 and reflected by the second reflection surface 332, Can be irradiated to the outside through the other area of the light source 340.

Accordingly, the light generated from the linear light source module 200 is irradiated to the outside through the exit surface 340 of the lens 300 having the above-described configuration, A surface emitting image can be realized.

At this time, since the optics 350 are formed on the first incident surface 310 of the lens 300, the light incident through the first incident surface 310 and the light incident through the second incident surface 320 and the third incident surface 310, The light incident through the exit surface 340 may be irradiated in different directions when the light is emitted through the exit surface 340 and irradiated to the outside.

6, after entering through the second incident surface 320 and the third incident surface 330 and being reflected by the first reflection surface 322 and the second reflection surface 332, The light L1 emitted through the first optical surface 340 is incident on the first optical surface 352 of the optic 350 while being incident on the first incident surface 310 while being irradiated in a first direction substantially parallel to the optical axis. The light L2 emitted through the exit surface 340 is irradiated in a second direction different from the first direction.

In other words, the light L1 that is incident through the second incident surface 320 and the third incident surface 330 of the lens 300 and exits through the exit surface 340 and the first incident surface 310 And the light L2 can be radiated in different directions through the exit surface 340.

Fig. 7 is a view schematically showing an outgoing path of light in a state where a vehicle lamp according to a second embodiment of the present invention is mounted on a vehicle. Fig.

As shown in Fig. 7, the vehicle lamp 100 constructed as above can be mounted on the front or rear corner of the vehicle so that visibility can be ensured by drivers, pedestrians, As shown in FIG.

Therefore, as the light radiated to the outside from the on-vehicle lamp 100 is irradiated in an oblique direction with respect to the front or rear of the vehicle, it may happen that the front vehicle driver or the rear vehicle driver can not properly secure visibility .

7, when the light radiated to the outside from the on-vehicle lamp 100 is irradiated in the first direction and the second direction, as in the second embodiment of the present invention, Or the visibility to the driver of the rear vehicle is more reliably provided, so that the safety driving can be achieved.

For example, assuming that the first direction is an inclined direction with respect to the front or rear of the vehicle, since the second direction in which the light is refracted by the optic 350 is the front or rear of the vehicle, As more light is irradiated toward the rear side, the above-mentioned action and effect can be obtained.

The vehicle lamp 500 according to the fourth embodiment of the present invention is different from the lamp 500 according to the third embodiment described above in that a plurality of optics 750 The same reference numerals are assigned to the same parts and the repeated description thereof will be omitted.

13 and 14, the first incident surface 710 of the lens 700 is provided with a first optic surface 752 inclined at a predetermined angle in the first direction and a second optic surface 752 inclined from the first optic surface 752 And the second optic surface 754, which is inclined at a predetermined angle in the second direction, are formed at regular intervals.

14, the optic 750 includes a first optical surface 752 inclined at a small angle toward the first direction with respect to the first incident surface 710, The second optic surface 752 may include a second optic surface 754 that is tilted at an angle greater than the tilt angle of the first optic surface 752, Can be formed larger than the area.

In this case, since the second optic surface 754 is not a section through which light is substantially transmitted, it may be formed at right angles to the first incident surface 710. However, when the lens is injection molded using a mold, It is preferable that the second optic face 754 is formed to be inclined at a large angle with respect to the first optic face 752 because there is a risk that a mold lack may occur when the two optic faces 754 are at right angles.

The inflection point 756 of the first optic surface 752 and the second optic surface 754 in one optic 750 and the first optic surface 752 in the adjacent optic 750 It is desirable that the interval between the second optical surface 754 and the inflection point 756 is designed to be within about 10 mm for uniformity of brightness and light control.

It is preferable that the angle of the first optic surface 752 and the second optic surface 754 of the optic 750 is an obtuse angle and the angle of the obtuse angle is less than 170 degrees.

As described above, the first optic surface 752 is formed to have a larger cross-sectional area than the second optic surface 754, so that the light incident through the first incident surface 710 of the lens 700 is optically 750 by the first optic surface 752. [

At this time, the light incident through the first incident surface 710 of the lens 700 may be refracted in the direction opposite to the oblique direction of the first optic surface 752 of the optic 750, and may be externally irradiated.

The light irradiation path of the vehicle lamp 500 having the above-described configuration will now be described with reference to FIGS. 11 and 14. FIG.

In the case of the vehicle lamp 500 according to the fourth embodiment of the present invention, the configuration other than the optic 750 formed on the first incident surface 710 of the lens 700, as described above, The path of the light emitted from the linear light source module 600 will be described with reference to FIG. 11 once again supporting the third embodiment.

11, part of the light emitted from the light source 610 of the linear light source module 600 is incident through the first incident surface 710 having a convex shape toward the receiving space 702, And can be irradiated to the outside through the first exit surface 740.

Part of the light emitted from the light source 610 of the linear light source module 600 is incident through the second incident surface 720 and reflected by the first reflection surface 722, And can be irradiated to the outside through the exit surface 742.

Part of the light emitted from the light source 610 of the linear light source module 600 is incident through the third incident surface 730 and reflected by the second reflecting surface 732, And can be irradiated to the outside through the exit surface 744.

Accordingly, the light emitted from the linear light source module 600 can be transmitted through the first exit surface 740, the second exit surface 742, and the third exit surface 744 of the lens 700, So that it is possible to realize a surface emission image similar to a single line.

At this time, since the optics 750 are formed on the first incident surface 710 of the lens 700, the light incident through the first incident surface 710 and the light incident through the second incident surface 720 and the third incident surface 710, When the light incident through the first exit surface 740 and the second exit surface 742 and the third exit surface 744 are irradiated to the outside through the first exit surface 740 and the second exit surface 730, Lt; / RTI &gt;

14, after being incident through the second incident surface 720 and the third incident surface 730 and reflected by the first reflection surface 722 and the second reflection surface 732, The light L3 emitted through the exit surface 742 and the third exit surface 744 is incident on the first incident surface 710 while being irradiated in a first direction substantially parallel to the optical axis, The light L4 emitted through the first exit surface 740 is irradiated in a second direction different from the first direction after being refracted by the first optic surface 752 of the first exit surface 740. [

In other words, the light L3 that is incident through the second incident surface 720 and the third incident surface 730 of the lens 700 and exits through the second exit surface 742 and the third exit surface 744, And the light L4 that is incident through the first incident surface 710 and emitted through the first exit surface 740 may be radiated in different directions.

Fig. 15 is a view schematically showing an outgoing path of light in a state where a vehicle lamp according to a fourth embodiment of the present invention is mounted on a vehicle. Fig.

As shown in Fig. 15, the vehicle lamp 500 having such a configuration can be mounted on the front or rear corner of the vehicle so that the driver, pedestrian, or the like, other than the front, rear, or side of the vehicle can secure visibility .

Therefore, as the light radiated to the outside from the on-vehicle lamp 500 is irradiated in an oblique direction with respect to the front or rear of the vehicle, it may happen that the front vehicle driver or the rear vehicle driver can not properly secure visibility .

By the way, as in the fourth embodiment of the present invention, when the light radiated to the outside from the on-vehicle lamp 500 is irradiated in the first direction and the second direction as shown in Fig. 14, Or the visibility to the driver of the rear vehicle is more reliably provided, so that the safety driving can be achieved.

For example, assuming that the first direction is an inclined direction with respect to the front or rear of the vehicle, the second direction in which the light is refracted by the optic 750 is the front or rear of the vehicle, As more light is irradiated toward the rear side, the above-mentioned action and effect can be obtained.

Fig. 16A is a view showing a distribution of light irradiated by the vehicle lamp 500 according to the third embodiment of the present invention, Fig. 16B is a view showing the distribution of light irradiated by the vehicle lamp 500 according to the fourth embodiment of the present invention Fig.

16A, when the optic 750 is not formed on the first incident surface 710 of the lens 700, the light is emitted through the first exit surface 740 to the third exit surface 744, All of the light to be irradiated is irradiated in one direction, so that it can be seen that the light irradiation range is slightly shifted in one direction with respect to the center.

That is, it can be seen that the vehicle is biased in the lateral direction with respect to the longitudinal center of the vehicle.

16B, when the optic 750 is formed on the first incident surface 710 of the lens 700 as in the fourth embodiment of the present invention, the light is emitted through the first exit surface 740, And light emitted to the outside through the second exit surface 742 and the third exit surface 744 is emitted to the outside in the lateral direction of the vehicle It can be confirmed that the irradiation range is broader toward the front or rear of the vehicle with respect to the center by being irradiated in the first direction.

Therefore, it is possible to provide the visibility to the front vehicle driver or the rear vehicle driver of the vehicle more reliably, thereby making it possible to securely operate the vehicle.

17 is a front view showing a state in which support rods are integrally formed on both sides of the lens of the vehicle lamp according to the embodiments of the present invention.

Referring to FIG. 17, a support 800 may be integrally formed on both side regions of a lens 700 that can be applied to a vehicle lamp 500 according to embodiments of the present invention.

When the lens 700 is molded by a mold, the support frame 800 may be integrally formed. The support frame 800 may be mounted on the lamp housing of the vehicle lamp 500 to fix the lens 700 And the like.

At this time, the lens 700 may be formed in a substantially hemispherical shape as described above, and it is preferable that the lens 700 is formed so as to extend from both ends of the emitting surface with the widest width of the emitting surface region.

This is to facilitate separation from the mold when the lens 700 and the support 800 are integrally molded and manufactured.

For example, when the support 800 is formed so as to extend from a relatively narrow reflective surface, a part of the mold is present between the both side ends of the exit face having a relatively large width and the region where the support is extended, It is difficult to separate the support from the mold due to the lack of the mold. It is preferable that the support is formed so as to extend from both ends of the exit surface of the lens 700.
