The lamp modules in the lamp assembly include halogen lamps, high pressure gas discharge lamps (High intensity Discharge, HID), light sources such as light emitting diodes (light emitting diode, LEDs). The car light module luminance is lower when opening, in order to promote the luminance of car light module to the illumination needs, needs to carry out the pressure boost to the voltage of input car light module, and instantaneous high pressure can lead to car light module to produce the heat big, if the heat can't in time release, will restrict the life of car light module. The car lamp assembly is internally provided with the heat radiating device, and the larger the heat radiating area of the heat radiating device is, the larger the heat radiating capacity is. On the other hand, in order to adjust the shutter position, an additional driver is required in the lamp assembly.

The related car lamp assembly adopts fixed optical elements, two groups of light source modules respectively form high beam and low beam, and the two groups of light sources are arranged on the same circuit board. The circuit board is connected with the heat dissipation module. The two groups of light source modules are arranged on two opposite side surfaces of the circuit board, so that light rays generated by the two groups of light source modules are emitted to two opposite directions. However, in order to avoid the interference of the heat dissipation module to the light, the heat dissipation module needs to be attached to a side surface of the circuit board different from the mounting surface of the light source module, or the heat dissipation module is subjected to avoidance treatment. This will lead to the area of contact of circuit board and heat dissipation module to reduce, reduces radiating efficiency, and then influences the life of light source module.

The light generated by the first light source module and the second light source module is reflected by the first reflecting surface 321 and the second reflecting surface 322 to be directed to the ellipsoidal lens 100. The first reflecting surface 321 is disposed opposite to the reflecting surface of the first reflecting bowl 312, and the second reflecting surface 322 is disposed opposite to the reflecting surface of the second reflecting bowl 314.

Meanwhile, the first light emitting portion 311 and the second light emitting portion 313 share one heat conducting platform 331, so that the number of heat dissipation modules 33 is reduced. Among the important factors of the heat dissipation efficiency, the heat dissipation area is mainly limited, and the larger the heat dissipation area is, the more heat is exchanged in unit time, so that the heat dissipation module 33 occupies more space in the lighting assembly. The volume occupied by the heat dissipation modules 33 in the lighting assembly can be greatly reduced by reducing the number of the heat dissipation modules 33, so that the cost is saved and the lighting assembly is convenient to miniaturize.

Further, as shown in fig. 3 and 4, the heat dissipation module 33 further includes a heat dissipation fin 332, the heat dissipation fin 332 is connected to the heat conduction platform 331, and heat on the heat conduction platform 331 is dissipated outwards from the heat dissipation fin 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 penetrate through the second mounting opening 22 and extend into the hollow cavity of the bracket 200, the heat radiating fins 332 are located outside the bracket 200, and the optical module 32 is also located in the hollow cavity of the bracket 200. The ellipsoidal lens 100 is installed in the first mounting opening 21 to connect the ellipsoidal 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), two opposite sides of the body are a first heat dissipation surface 3311 and a second heat dissipation surface 3312, and the mounting bracket is disposed on two opposite sides of the body. The mounting brackets correspondingly fit on the end surfaces of the brackets 200 and are simultaneously connected with the cooling fins 332, so that the body and the cooling fins 332 are respectively positioned on two opposite sides of the mounting brackets. When the mounting bracket is connected with the end face of the bracket 200, the first light source module and the second light source module are arranged in 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 is more smoothly diffused.

In this scheme, in order to limit the light reflected by the first light source module and the second light source module from being emitted from the gap between the first light source module, the second light source module and the ellipsoidal lens 100 without passing through the ellipsoidal lens 100, the light leakage problem occurs in the lighting assembly. By accommodating 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, so that the light of the first light source module and the second light source module can only be emitted through the ellipsoidal lens 100.

In one embodiment, the optical module 32 is fixedly connected to the heat dissipation module 33. Fig. 6 and 7 are schematic diagrams showing the detachment of the optical module and the heat dissipation module according to an embodiment of the utility model, and fig. 8 is a schematic diagram showing the detachment of the optical module and the heat dissipation module according to an embodiment of the utility model.

Secondly, this lighting assembly has reduced spare part, simplifies lighting assembly structure, can practice thrift the cost, simultaneously, conveniently reduces lighting assembly's volume. Finally, the temperature in the lighting assembly will be improved when the light source module is in operation, if the driver is adopted, the driver will work in a high-temperature environment for a long time, and fatigue of the driver is more easily caused, so that damage is caused, and the service life is influenced. In this solution, the optical module 32 is connected by a fixed rigid connection, so that the position of the optical module 32 is more stable, and the service life of the lighting assembly is long.
