Abstract
Description
Technical Field
[0001] The utility model relates to the field of vehicle lamp lighting, and more specifically, to a forward light emitting structure and a vehicle lamp thereof. Background Art
[0002] Due to the limited volume of the existing headlamp, the high beam reflector and the low beam emitter are arranged closely together, one above and the other below.
[0003] The upper portion of the upper lamp reflector can bear the light output module, but the lower lamp reflector is difficult to be placed with the light output module in the same manner.
[0004] In some related technologies, reference Figure 1 By setting the light output module on the side of the lamp reflector below, side light output is used.
[0005] The disadvantage of this method is that the side-mounted light output module is more easily observed directly, causing glare. The light output module includes a PCB board with LED lamp beads and a heat sink for heat dissipation. The PCB board and the heat sink also need to be placed on the side, but because the side of the reflector is very thin, it is difficult to fix the light output module to the side of the reflector with fasteners. To solve this problem, either a folding edge is set on the side of the reflector, which increases the material cost and the corresponding mold cost, and also encroaches on the width direction of the car light; another way is to provide an additional independent frame to serve as an adapter to connect the light output module and the reflector.
[0006] The present application aims to provide a forward light emitting structure and a vehicle lamp thereof, in which a light emitting module is arranged on the top of a reflector below without adding extra costs. Summary of the invention
[0007] The utility model overcomes the shortcoming of the existing headlamp integrating high beam and low beam that it is difficult to arrange the light output module corresponding to the lower reflector, and provides a forward light output structure, which can arrange the light output module on the top of the lower reflector without increasing additional costs.

The step is used to locate the light output module, to indicate that it is in place, and to reduce the difficulty of assembly.
[0015] Preferably, a reinforcing rib is provided on the bottom surface of the convex plate, and the reinforcing rib is used to enhance the strength of the convex plate so that the convex plate can bear the weight of the light output module.

The PCB board is attached to a part of the surface of the convex plate and the convex strip, and light emitted by an LED lamp on the PCB board is incident on the high-beam reflector through the through hole, and the heat sink is attached to the PCB board.

[0039] Example:
[0040] A structure that emits light in the forward direction. Figure 2 As shown, it includes a first depression 1 and a second depression 2 that are concave along a first direction, and the second depression 2 is located above the first depression 1. The depression depths of the first depression 1 and the second depression 2 are both deep at the top and shallow at the bottom, and the tops of the backs of the first depression 1 and the second depression 2 are both planes or curved surfaces that are approximately planes. The tops of the first depression 1 and the second depression 2 both have through holes.
[0041] On this basis, the top of the first recess 1 further has a convex plate 3 , which is arranged along the first direction and flush with the top of the first recess 1 . The convex plate 3 is provided with a through hole 4 penetrating the top of the first recess 1 .
[0042] On the basis of the above embodiments, corresponding light output modules are installed to form corresponding vehicle lights.
[0043] Combination Figure 2 , 3 A vehicle lamp includes a reflector, a PCB board 15 and a heat sink 16. The reflector includes the structure for emitting light in the forward direction as described above. The first recess 1 forms a high-beam reflector, and the second recess 2 forms a low-beam reflector. The light emitted by the LED lamp on the PCB board 15 is incident on the high-beam reflector through the through hole 4. The heat sink 16 is attached to the PCB board 15.
[0044] Ginseng Figure 5 As shown, two folded edges 14 are provided on the heat sink 16, and the two folded edges 14 are respectively fitted with opposite sides of the PCB board 15. The heat sink 16 and the PCB board 15 are fixedly connected by a second fastener 11.
[0045] The bottom surface of the protruding plate 3 is provided with a reinforcing rib 7. The reinforcing rib 7 is used to enhance the strength of the protruding plate 3 so that the protruding plate 3 can bear the weight of the light output module. The reinforcing rib 7 is provided with a plurality of positioning column holes 8, and the axial direction of the positioning column holes 8 is set along the first direction. The reinforcing rib 7 positions the light output module through the positioning column holes 8. The reinforcing rib 7 is provided with a guide column 9, and the axis of the guide column 9 is set along the first direction. The guide column 9 is used to achieve pre-positioning before locking the fastener, thereby reducing the difficulty of assembly. The radiator 16 is provided with a guide hole 12, and the guide column 9 is inserted into the guide hole 12. The radiator 16 is fixedly connected to the positioning column hole 8 through the first fastener 10, and the first fastener 10 and the second fastener 1 are vertically arranged.
[0046] The convex plate 3 is provided with a convex strip 5. The convex plate 3 has a draft angle, with a thin free end and a thick fixed end. This is based not only on the process angle, but also on the heat dissipation capacity of the light output module. The PCB board 15 is attached to a part of the surface of the convex plate 3 and the convex strip 5. The convex strip 5 is used to install the light output module. Since the light output module generates a lot of heat when in use, the convex strip 5 can support the light output module, thereby increasing the contact area with the air and improving the heat dissipation efficiency.
[0047] The convex plate 3 is provided with a step 6, and the portion of the step 6 close to the first recess 1 is higher than the portion of the step 6 away from the first recess 1. The step 6 is used to locate the light output module, to indicate that it is in place, and to reduce the difficulty of assembly. The convex plate 3 is provided with a limiting edge 13, and the heat sink 16 and the PCB board 15 are positioned by the limiting edge 13 and the step 6.
[0048] In addition to forming a high beam reflector and a low beam reflector, the reflector also provides installation and positioning of the light output module of the high beam reflector. The PCB board 15 is installed on part of the surface of the convex plate 3 and the convex strip 5 to increase the contact area with the air and improve the heat dissipation efficiency.
[0049] The reflector is an integral injection-molded structure, and the first direction is the mold opening direction of the reflector. The first recess 1 and the second recess 2 form a high-beam reflector and a low-beam reflector for collecting light. The convex surface of the back of the first recess 1 below is also along the first direction, which can simplify the design difficulty of the mold. The convex plate 3 is used to install the light-emitting mold. The through hole 4 allows the light emitted by the optical module to enter the first recess 1.
[0050] This makes the first recess 1 the deepest and the second recess 2 the shallowest at the height corresponding to the convex plate 3, thereby providing space for the through hole 4 and installation space for the light output module.
[0051] Through the structure provided in the present application, the first recess 1 at the bottom supports the light output module located at the top, which can avoid glare and does not require the provision of a folded edge 14 and an independent frame for transit connection, thereby achieving cost reduction and efficiency improvement.
