Description

lighting assembly

Technical field

The present application relates to the field of lighting technology, and in particular to a lighting assembly suitable for automobiles.

Background technique

Car lights are an important part of a vehicle and play an important role in vehicle driving safety. The car light assembly includes a car light module, a lens and a baffle. The light path of the car light module is adjusted through the baffle, so that different light rays pass through the lens to form high beam and low beam. The car light modules in the relevant car light assemblies include light sources such as halogen lamps, high-pressure discharge lamps (High intensity Discharge, HID), and light emitting diodes (light emitting diodes, LED). The brightness of the car light module is low when it is turned on. In order to increase the brightness of the car light module to the lighting requirement, the voltage input to the car light module needs to be boosted. The instantaneous high voltage will cause the car light module to generate a lot of heat. If the heat cannot be released in time, the service life of the lamp module will be limited. There is a heat dissipation device in the car light assembly, and the larger the heat dissipation area of the heat dissipation device, the greater the heat dissipation. On the other hand, in order to adjust the baffle position, an additional driver is required in the vehicle light assembly. Reserved installation space for the heat dissipation device and driver will increase the size of the lamp assembly, making it difficult to miniaturize the lamp assembly.

The relevant car light assembly uses fixed optical components. Two sets of light source modules form high beam and low beam respectively. The two sets of light sources are installed on the same circuit board. The circuit board is connected to the heat dissipation module. Two sets of light source modules are installed on opposite sides of the circuit board, so that the light generated by the two sets of light source modules is emitted in two opposite directions. However, in order to avoid the interference of light by the heat dissipation module, the heat dissipation module needs to be attached to the side of the circuit board that is different from the mounting surface of the light source module, or the heat dissipation module needs to be avoided. This will lead to a reduction in the contact area between the circuit board and the heat dissipation module, lowering the heat dissipation efficiency, and thus affecting the service life of the light source module.

Specifically, the bracket 200 has a hollow cavity inside, and a first mounting port 21 and a second mounting port 22 are respectively formed on both end surfaces of the bracket 200. The first mounting port 21 and the second mounting port 22 communicate with the hollow cavity. The ellipsoid lens 100 and the projection assembly 300 are installed in the first installation port 21 and the second installation port 22 respectively. The relative position of the ellipsoid lens 100 and the projection assembly 300 is fixed by the bracket 200 .

In this solution, the projection component 300 includes a light source module 31 , an optical module 32 and a heat dissipation module 33 . Referring to Figures 3 and 4, Figure 3 shows a schematic structural diagram of the projection component within the lighting assembly in one embodiment of the present application, and Figure 4 shows the explosion of the projection component within the lighting assembly in one embodiment of the present application. Schematic diagram. The light source module 31 includes a first light source module and a second light source module. The first light source module includes a first light-emitting part 311 and a first reflective bowl 312. The first reflective bowl 312 is used to reflect the light emitted by the first light-emitting part 311. The second light source module includes a second light-emitting part 313 and a second reflective bowl 314. The second reflective bowl 314 is used to reflect the light emitted by the second light-emitting part 313. The heat dissipation module 33 includes a heat conduction platform 331. In conjunction with FIG. 5, FIG. 5 shows a cross-sectional view of the heat dissipation module and the light source module in an embodiment of the present application. The thermal conductive platform 331 has a first heat dissipation surface 3311 and a second heat dissipation surface 3312 arranged oppositely. The first light-emitting part 311 is bonded to the first heat dissipation surface 3311, and the second light-emitting part 313 is bonded to the second heat dissipation surface 3312. The optical module 32 is relatively fixed between the ellipsoid lens 100 and the thermal conductive platform 331 . The optical module 32 projects the light reflected by the first reflective bowl 312 and the second reflective bowl 314 to the ellipsoid lens 100 .

Exemplarily, with reference to Figures 6 and 7, Figure 6 shows a schematic structural diagram of the optical module in the lighting assembly in an embodiment of the present application from a first perspective, and Figure 7 shows a schematic structural diagram of the optical module in the lighting assembly in an embodiment of the present application. Structural diagram of the optical module in the assembly from a second perspective. The optical module 32 has a first reflective surface 321 and a second reflective surface 322 arranged oppositely. The first reflective surface 321 is located on the reflected light path of the first reflective bowl 312 , and the second reflective surface 322 is located on the reflected light path of the second reflective bowl 314 . On the way. The light generated by the first light source module and the second light source module is reflected by the first reflective surface 321 and the second reflective surface 322 respectively and is projected to the ellipsoid lens 100 . The first reflective surface 321 is arranged opposite to the reflective surface of the first reflective bowl 312 , and the second reflective surface 322 is arranged opposite to the reflective surface of the second reflective bowl 314 . The first light-emitting part 311 emits light through the optical path of the first reflective bowl 312, the first reflective surface 321, and the ellipsoid lens 100 to form a low beam. The second light-emitting part 313 emits light through the optical path of the second reflective bowl 314, the second reflective surface 322, and the ellipsoid lens 100 to form high beam.

It should be noted that the light generated by the first light-emitting part 311 passing through the ellipsoid lens 100 includes but is not limited to forming low beam, and the light generated by the second light-emitting part 313 passing through the ellipsoid lens 100 includes but is not limited to forming high beam. For example, the light generated by the first light-emitting part 311 or the second light-emitting part 313 passes through the ellipsoid lens 100 to form a low beam, and the light generated by the first light-emitting part 311 and the second light-emitting part 313 simultaneously passes through the ellipsoid lens 100 to form a high beam. , the above scheme can also form high and low beams respectively, and should also be regarded as a specific implementation scheme of the present application.

In this embodiment, the optical module 32 is fixedly arranged relative to the ellipsoid lens 100, the thermal conductive platform 331, the first light-emitting part 311, and the second light-emitting part 313. The first light-emitting part 311 and the second light-emitting part 313 form far and low beams. , so that in this embodiment, the driving module that drives the optical module 32 to adjust the position is reduced, and the components in the lighting assembly are reduced, thereby simplifying the lighting assembly structure. At the same time, the first light-emitting part 311 and the second light-emitting part 313 share a thermal conductive platform 331 , reducing the number of heat dissipation modules 33 . Among them, the important factor of heat dissipation efficiency is mainly limited by the heat dissipation area. The larger the heat dissipation area, the more heat is exchanged per unit time, so the heat dissipation module 33 takes up more space in the lighting assembly. By reducing the number of heat dissipation modules 33, the volume occupied by the heat dissipation modules 33 in the lighting assembly can be greatly reduced, saving costs and facilitating miniaturization of the lighting assembly.

Specifically, as shown in FIG. 5 , the first light-emitting part 311 includes a first circuit substrate 3111 and a first lamp bead 3112 . The first lamp bead 3112 and the first heat dissipation surface 3311 are provided on two opposite surfaces of the first circuit substrate 3111 . The second light-emitting part 313 includes a second circuit substrate 3131 and a second lamp bead 3132. The second lamp bead 3132 and the second heat dissipation surface 3312 are provided on two opposite surfaces of the second circuit substrate 3131. By attaching the first circuit substrate 3111 and the second circuit substrate 3131 to the first heat dissipation surface 3311 and the second heat dissipation surface 3312 of the heat conduction platform 331 respectively, it is convenient to increase the number of the first circuit substrate 3111 and the second circuit substrate 3131 The contact area with the heat conduction platform 331 improves the heat dissipation efficiency. The heat generated by the first lamp bead 3112 and the second lamp bead 3132 can be spread from the corresponding first circuit substrate 3111 and the second circuit substrate 3131 along the heat conduction platform 331 in time. , extending the service life of the lighting assembly.

Further, as shown in Figures 3 and 4, the heat dissipation module 33 also includes a heat sink 332. The heat sink 332 is connected to the heat conduction platform 331, and the heat on the heat conduction platform 331 spreads outward from the heat sink 332. The first light source module and the second light source module are installed on the heat conduction platform 331 . The first light source module and the second light source module extend from the second installation opening 22 into the hollow cavity of the bracket 200 , and the heat sink 332 is located outside the bracket 200 , and the optical module 32 is also located in the hollow cavity of the bracket 200 . The ellipsoid lens 100 is installed in the first installation port 21 to connect the ellipsoid lens 100, the bracket 200, and the projection assembly 300. Specifically, the heat conduction platform 331 includes a body and a mounting bracket (not shown). The two opposite surfaces of the body are the first heat dissipation surface 3311 and the second heat dissipation surface 3312. The mounting brackets are provided on two opposite sides of the body. The mounting bracket corresponds to the end surface of the bracket 200 and is connected to the heat sink 332 at the same time, so that the body and the heat sink 332 are located on opposite sides of the mounting bracket. When the mounting bracket is connected to the end surface of the bracket 200, the first light source module and the second light source module are inserted into the hollow cavity. The heat sink 332 is located outside the bracket 200, so that the heat sink 332 is exposed to the external environment, and the heat on the heat sink 332 spreads more smoothly.

In this solution, in order to limit the light reflected by the first light source module and the second light source module from passing through the ellipsoid lens 100 from the gap between the first light source module, the second light source module and the ellipsoid lens 100 Ejected from time to time, causing light leakage problems in the lighting assembly. By housing the first light source module and the second light source module in the hollow cavity, the inner wall of the bracket 200 blocks the light reflected by the first light source module and the second light source module, causing the first light source module and the second light source module to The light from the light source module can only be emitted through the ellipsoid lens 100 .

In a specific embodiment, the optical module 32 is fixedly connected to the heat dissipation module 33 . As shown in Figures 6 and 7, combined with Figure 8, Figure 8 shows a disassembled schematic diagram of the optical module and the heat dissipation module in an embodiment of the present application. Specifically, the thermally conductive platform 331 extends outward to form a carrier 333, and the carrier 333 extends from the thermally conductive platform 331 in a direction away from the carrier 333. The number of stages 333 is two, and the two stages 333 are arranged at intervals. The optical module 32 includes a connecting portion 323. The connecting portion 323 is arranged on opposite sides of the first reflective surface 321 and the second reflective surface 322. The two connecting portions 323 are respectively connected to the corresponding carriers 333, so that the optical module 32 is installed on the two carriers 333. The gap between the two stages 333 is an escape portion 335, and the reflected light path of the first reflective bowl 312 or the second reflective bowl 314 passes through the escape portion 335, so that the light reflected by the first reflective bowl 312 and the second reflective bowl 314 can be smoothly transmitted. are projected onto the corresponding first reflective surface 321 and second reflective surface 322.

Exemplarily, the connecting part 323 is provided with a positioning hole, and the matching part 334 includes a positioning post that matches the positioning hole, and is sleeved on the positioning post through the positioning hole, so that the connecting part 323 is connected to the matching part 334, thereby connecting the optical module. The group 32 is fixed on the carrier 333 .

In another specific embodiment, the optical module 32 is fixedly connected to the inner wall of the cavity in the bracket 200 . Since the ellipsoid lens 100 and the projection component 300 are both fixedly installed on the bracket 200 , the relative positions of the optical module 32 and the ellipsoid lens 100 and the projection component 300 are limited.

According to the above two specific embodiments, the relative positions of the optical module 32 and the ellipsoid lens 100 and the first light source module and the second light source module installed on the heat conduction platform 331 are fixed. In the above embodiments, the optical module 32 The first reflective surface 321 and the second reflective surface 322 are used to reflect the light projected by the two sets of light source modules. The optical module 32 does not need to use a driver to form different high and low beam patterns by adjusting the optical module 32 . The optical module 32 is located at the focus of the ellipsoid lens 100 .

First, the driving module is adjusting the optical module 32, and the angular size tolerance of the optical module 32 is large during adjustment, making it easier for the edge lines of the low beam and the high beam to not overlap. In this solution, the turning on and off of the first light source module or the second light source module is directly used, and the reflection of the two sets of light source modules on the optical module 32 realizes switching of the low beam and high beam functions, effectively improving the The coincidence accuracy of the light focus and the focus of the ellipsoid lens 100 prevents the cutoff line from being colored, the near and low beam light patterns are more uniform, and the low beam and high beam edge lines overlap, so that the lighting assembly can obtain a better light pattern effect. Secondly, the lighting assembly reduces components and simplifies the structure of the lighting assembly, which can save costs and at the same time facilitate the reduction of the size of the lighting assembly. Finally, the light source module will increase the temperature within the lighting assembly when working. If a driver is used, the driver will work in a high-temperature environment for a long time, which is more likely to cause driver fatigue, thereby causing damage and affecting the service life. In this solution, the optical module 32 is fixed and rigidly connected to make the position of the optical module 32 more stable, and the lighting assembly has a long service life.

In some embodiments of the present application, the ellipsoid lens 100 includes a light incident surface and a light exit surface arranged oppositely, and both the light incident surface and the light exit surface are convex free-form surfaces. The ellipsoid lens 100 includes a polymethyl methacrylate layer.
