[0002] With the universal application and development of automobile headlamp technology, the demand for vehicle lamp modeling is increasing, and the vehicle lamp as an external component of the automobile generates certain heat in the process of realizing good lighting function, so a heat dissipation device needs to be added to avoid the temperature of the vehicle lamp being too high and prevent the internal parts of the vehicle lamp from being damaged after long time work. The built-in fan is widely used in the design of the vehicle lamp heat dissipation device as a functional element that can not only reduce the size of the vehicle lamp but also reduce the internal temperature.

At this time, if the number of fans is increased, not only will the structure be complex due to the increase of parts, but also the overall size of the vehicle lamp will inevitably be increased, causing waste of resources and space and increase of production cost.

[0029] Please refer to Figures 1 to 3 The embodiment of the application provides a lighting module 100, comprising a lighting assembly 10 and a fan 20, the lighting assembly 10 comprises a plurality of stacked lighting modules 11, along the stacking direction, the fan 20 is arranged on the first side of the lighting assembly 10, the included angle α between the light emitting direction x of the lighting module 11 on the second side of the lighting assembly 10 and the air outlet direction y of the fan 20 is an acute angle, and the first side and the second side are oppositely arranged. The lighting module 100 can solve the problems of poor module heat dissipation effect in the single-fan scheme of the prior art and the problems of more parts, complex structure, large size and high cost in the multi-fan scheme of the prior art by reasonably arranging the installation direction of the fan 20 relative to the lighting assembly 10 comprising a plurality of lighting modules 11.

[0030] It should be noted that, as Figure 1 And Figure 2 The lighting module 100 comprises a lighting assembly 10 and a fan 20, so as to realize the lighting function of the vehicle through the lighting assembly 10 and dissipate the heat generated by the operation of the lighting assembly 10 through the fan 20. The lighting assembly 10 comprises a plurality of stacked lighting modules 11 (such as a high-low beam integrated module, an ADB module, etc.), so as to realize different lighting effects through different lighting modules 11. Along the stacking direction, the fan 20 is arranged on the first side of the lighting assembly 10, the included angle α between the light emitting direction x of the lighting module 11 on the second side of the lighting assembly 10 and the air outlet direction y of the fan 20 is an acute angle (such as 85°, 86°, 87° or 88°, etc.), and the first side and the second side are oppositely arranged.

[0031] In other words, the application can cover the lighting assembly 10 along the stacking direction of the plurality of lighting modules 11 by arranging the fan 20 on the outer side (i.e. the first side) of the lighting assembly 10, and tilting the surface of the fan 20 to a certain extent (e.g. 2-5°), so that the air outlet range of the fan 20 can not only cover the lighting modules 11 close to the side (i.e. the first side) of the fan 20, but also cover the lighting modules 11 away from the side (i.e. the second side) of the fan 20, thereby achieving effective cooling of all lighting modules 11. Compared with the prior art, the application can solve the problems of poor module heat dissipation effect of the single-fan scheme of the multi-module setting and the problems of more parts, complex structure, large size and high cost of the multi-fan scheme of the multi-module setting by reasonably arranging the installation orientation of the fan 20 relative to the lighting assembly 10 comprising a plurality of lighting modules 11.

[0032] For ease of understanding, as shown in Figures 1 to 3 In this embodiment, the lighting assembly 10 comprises two lighting modules 11 (i.e. the first lighting module 11a and the second lighting module 11b) as an example for explanation and description. Among them, the first lighting module 11a and the second lighting module 11b are stacked in the direction (i.e. the vertical direction), and the fan 20 is arranged on the first side (i.e. the lower side) of the lighting assembly 10 (i.e. the second lighting module 11b), and the included angle α between the light outlet direction x of the lighting module 11 (i.e. the first lighting module 11a) on the second side (i.e. the upper side) of the lighting assembly 10 and the air outlet direction y of the fan 20 is an acute angle. Since the surface of the fan 20 is tilted to a certain extent towards the side close to the first lighting module 11a, the air outlet range of the fan 20 can not only cover the lighting modules 11 close to the side (i.e. the first side) of the fan 20, but also cover the lighting modules 11 away from the side (i.e. the second side) of the fan 20, thereby achieving effective cooling of all lighting modules 11.

[0033] It should be noted that the air outlet direction y of the fan 20 is the normal direction of the surface of the fan 20, so that the included angle α between the light outlet direction x of the lighting module 11 on the second side of the lighting assembly 10 and the air outlet direction y of the fan 20 is an acute angle, which means that the surface of the fan 20 is tilted to a certain extent towards the side close to the first lighting module 11a, and the angle of the fan 20 is equal to 90°.

[0034] As an implementable manner, as shown in Figure 3As shown in the figure, each lighting module 11 comprises a lighting unit 111 and a heat dissipation unit 112 (for example, a heat sink) fixedly connected with one side of the lighting unit 111, and a fan 20 is fixedly installed on the heat dissipation unit 112 of the lighting module 11 at the first side, so as to dissipate heat from the lighting unit 111 through the heat dissipation unit 112 and further improve the heat dissipation effect of the heat dissipation unit 112 through the fan 20.

[0035] As an implementable manner, as shown in Figure 3 As shown in the figure, the heat dissipation unit 112 comprises a mounting substrate and a heat dissipation fin, one side of the mounting substrate is fixedly connected with the lighting unit 111 and in contact, and the other side of the mounting substrate is fixedly connected with the heat dissipation fin and in contact, so as to play a mounting and supporting role for the lighting unit 111 through the mounting substrate and transfer heat from the lighting unit 111 to the outside through the heat dissipation fin to achieve cooling.

[0036] As an implementable manner, as shown in Figure 2 and Figure 3 As shown in the figure, the number of heat dissipation fins comprises a plurality of heat dissipation fins, the plurality of heat dissipation fins are arranged at intervals, a heat dissipation channel is formed between adjacent two heat dissipation fins, and the airflow blown by the fan 20 flows to the heat dissipation channel and the lighting unit 111, so that the heat on the heat dissipation fins and the lighting unit 111 can be taken away through the heat exchange effect of the airflow, thereby achieving effective cooling of all the lighting modules 11.

[0037] As an implementable manner, as shown in Figure 3 As shown in the figure, the lighting unit 111 comprises a light source, a primary optical element 1112 and a light emitting element 1113, the light emitted by the light source is incident into the light emitting element 1113 through the primary optical element 1112 and is emitted to a target area through the light emitting element 1113 to form a target light shape, thereby playing a lighting role on the target area.

In this way, the light source can be controlled through the circuit board 1114, and the light source can also be mounted and supported through the circuit board 1114.

[0039] As an implementable manner, as shown in Figure 3As shown, the lighting unit 111 further comprises a fixing support 1115. In the actual assembly process, the circuit board 1114 can be first fixedly installed on the heat dissipation unit 112 through fasteners (such as screws), then the primary optical element 1112 (such as a condenser) is fixedly installed on the heat dissipation unit 112 through fasteners (such as screws), then the light emitting element 1113 (such as a lens) is fixedly installed on the fixing support 1115 through the connecting member 1116 (such as a lens ring), and finally the fixing support 1115 is installed on the heat dissipation unit 112 through fasteners (such as screws), so as to realize the assembly of the parts of the lighting unit 111. The above assembly method makes the structure more compact.

[0040] As shown in Figs. 1 and 2, the lighting module 11 comprises a lighting unit 111, a heat dissipation unit 112, and a connecting member 113.
