Detailed Implementation

[0029] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0030] Example 1

[0031] like Figures 1-3 An automotive headlight, as shown, includes: a heat dissipation substrate 10; a floodlight assembly 20 and a focusing assembly 30 disposed on the upper surface of the heat dissipation substrate 10; a supplementary light assembly 40 disposed above the floodlight assembly 20 and / or the focusing assembly 30; a light-emitting lens assembly 50 disposed in the optical path of the floodlight assembly 20, the focusing assembly 30, and the supplementary light assembly 40; and a beam-changing assembly 60 disposed in the optical path of the floodlight assembly 20 and the focusing assembly 30 for switching between high and low beams. The light-emitting lens assembly 50 includes a lens bracket 51 and a lens body 52 disposed on the lens bracket 51. The lens body 52 includes a first lens portion 521 for emitting light emitted from the floodlight assembly 20, a second lens portion 522 for emitting light emitted from the focusing assembly 30, and a third lens portion 523 for emitting light emitted from the supplementary light assembly 40. The light-incident surface and the light-emitting surface of the third lens portion 523 are parallel, and the third lens portion 523 is a solid lens structure.

[0032] The floodlight assembly 20 of the embodiment emits light rays in a wide angle range through the first lens part 521, the spotlight assembly 30 emits light rays with high brightness through the second lens part 522, and the light supplement assembly 40 emits light rays through the third lens part 523. Since the floodlight assembly 20 and the spotlight assembly 30 are both arranged on the upper surface of the heat dissipation substrate 10, the heat dissipation channels in the vertical direction do not overlap, so that the thickness of the heat dissipation substrate 10 can be increased to improve the heat dissipation effect; when low-beam lighting is achieved, the light shielding of the light rays of the floodlight assembly 20 and the spotlight assembly 30 by the light conversion assembly 60 is less, the light utilization rate is higher, and the low-beam lighting effect is better. In addition, the light supplement assembly 40 can further improve the high-beam lighting effect of the vehicle lamp. The third lens part 523 for emitting light rays of the light supplement assembly 40 is arranged to have parallel light-incoming surface and light-outgoing surface, so that the emission direction of the light rays emitted by the light supplement assembly 40 will not be changed, the original light emission characteristics of the light supplement assembly 40 can be retained, and then when the vehicle lamp is installed, the relative position between the light supplement assembly 40 and the third lens part 523 does not need to be adjusted specially, the light emission effect of the light supplement assembly 40 is not affected by the distance between the light supplement assembly 40 and the third lens part 523, the debugging process can be reduced, the assembly precision can be reduced, and the assembly efficiency can be improved. In addition, the third lens part 523 is a solid structure lens, which has better high-temperature resistance and longer service life than a hollow structure lens. It is worth mentioning that the spotlight assembly 30 and the floodlight assembly 20 of the present application refer to light source assemblies with different illumination range width and brightness of the finally emitted light. The illumination range width of the finally emitted light of the floodlight assembly 20 is greater than that of the spotlight assembly 30, and the brightness of the finally emitted light of the spotlight assembly 30 is higher than that of the floodlight assembly 20.

[0033] The light-incoming surface and the light-outgoing surface of the third lens part 523 are both planes, so that the processing technology is simple and the modeling is beautiful.

[0034] The first lens part 521, the second lens part 522 and the third lens part 523 are integrally formed, which is convenient for the manufacturing, assembly and disassembly of the lens body 52, avoids assembly errors, and has higher precision.

[0035] The first lens part 521, the second lens part 522 and the third lens part 523 are all glass lenses, which have good light transmission performance, good high-temperature resistance and low cost.

[0036] The first lens part 521 and the second lens part 522 are the same in size and shape, and have a beautiful appearance.

[0037] The lens holder 51 of the embodiment includes a lens seat 511 and a lens front cover 512, and the lens body 52 is pressed on the lens seat 511 through the lens front cover 512. During assembly, the lens body 52 is placed on the lens seat 511, and then the lens body 52 is pressed through the lens front cover 512 to achieve quick installation. Most of the existing light-emitting lenses of vehicle lamps only have the lens body 52 and the lens seat 511, and the lens body 52 needs to be pressed into the lens seat 511 by a strong device, and then fixed by a glue dispensing method. On the one hand, it is easy to cause damage to the lens seat 511 or the lens body 52, and on the other hand, it is time-consuming. In addition, since the lens holder 51 of the embodiment further includes the lens front cover 512, the lens front cover 512 can match most of the mounting hole positions on the market, and when the vehicle lamp is replaced, it can be directly clamped on the existing vehicle lamp mounting hole position. The existing vehicle lamp needs to be matched with a separate mounting frame to be assembled on the vehicle lamp mounting hole position.

[0038] The lens front cover 512 and the lens body 52 of the embodiment further have a buffer pad 53 for buffering. The buffer pad 53 can be a silica gel pad, which can ensure the pressing effect and reduce the damage caused by pressing. In other embodiments, a buffer pad can also be provided between the lens body and the lens seat.

The number of the light supplement light emitter 42 is 1-4. The light supplement light emitter 42 can be an LED or a laser.

[0040] Specifically, the light supplement light emitter 42 in the embodiment is an LED light emitter, the lens structure is a TIR lens 431, the number of the LED light emitter is three, the three LED light emitters are arranged in a linear arrangement, and the TIR lens 431 is arranged one-to-one corresponding to the light supplement light emitter 42. The TIR lens has good light collection efficiency, can improve the utilization rate of the light of the LED light emitter, and can strengthen the lighting effect.

[0041] Further, the center position of the light-emitting surface of the TIR lens 431 is provided with an optical pattern 433 for dispersing the emitted light, so that the emitted light has no clear contour line, and the light emitted by the three LED light emitters is uniformly mixed.

[0042] As shown in Figure 7As shown, the floodlight assembly 20 of the embodiment includes a first light emitter 21 and a first light cup 22 covering the first light emitter 21, and the spotlight assembly 30 includes a second light emitter 31 and a second light cup 32 covering the second light emitter 31. The size of the light spot on the focal plane of the first lens portion 521 after the light emitted by the first light emitter 21 is affected by the first light cup 22 is greater than the size of the light spot on the focal plane of the second lens portion 522 after the light emitted by the second light emitter 31 is affected by the second light cup 32. According to the principle of lens imaging, the illumination range of the light emitted by the floodlight assembly 20 through the first lens portion 521 is greater than the illumination range of the light emitted by the spotlight assembly 30 through the second lens portion 522, so the width of the light finally emitted by the floodlight assembly 20 is greater than the width of the light finally emitted by the spotlight assembly 30, and the brightness of the light finally emitted by the spotlight assembly 30 is greater than the brightness of the light finally emitted by the floodlight assembly 20. The first light emitter 21 and the second light emitter 31 of the embodiment are both LED light emitters.

[0043] The light-changing assembly 60 of the embodiment includes a light-blocking sheet 61 and a driving member for driving the light-blocking sheet 61 to change position. The light-blocking sheet 61 includes a first light-blocking sheet 611 for blocking the light of the floodlight assembly 20 and a second light-blocking sheet 612 for blocking the light of the spotlight assembly 30. The driving member can be a solenoid valve or other driving mechanism. When low-beam effect is needed, the first light-blocking sheet 611 is located in the light path of the floodlight assembly 20, the second light-blocking sheet 612 is located in the light path of the spotlight assembly 30, and the light emitted by the floodlight assembly 20 and the spotlight assembly 30 respectively passes through the first light-blocking sheet 611 and the second light-blocking sheet 612 to form a low-beam light pattern.

[0044] The automobile lamp of the embodiment further includes a heat dissipation fan 70 for dissipating heat from the heat dissipation substrate 10. The heat dissipation fan 70 is arranged at the tail portion of the heat dissipation substrate 10. The heat dissipation fan 70 includes a fan body 71 and a fan cover 72 cooperating with the fan body 71 and protecting the fan body 71.

The light supplement emitter 42 of the embodiment is an LED light emitter. The number of LED light emitters is two. The two LED light emitters are linearly arranged. The lens structure is a TIR lens 431. The TIR lens 431 is arranged in one-to-one correspondence with the light supplement emitter 42.

[0047] Embodiment 3

[0048] As Figure 10 , Figure 11 shown, the embodiment is similar to the structure and principle of embodiment 1 and embodiment 2, and the difference lies in that the light supplementing assembly 40 is different, the light supplementing luminous body 42 in the embodiment is an LED luminous body, the number of the LED luminous body is three, the three LED luminous bodies are linearly arranged, the lens structure is a Fresnel lens 432, and the Fresnel lens 432 is arranged in one-to-one correspondence with the light supplementing luminous body 42.
