Detailed Description

The technical solution of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

Example 1

As shown in figures 1 and 2, the side beacon light of the utility model is arranged between the chrome plating strips of the side window of the front and rear doors.

As shown in figure 3, the light guide shell 1 and the shading shell 4 are hermetically connected and then fixed on the fixing support 6, and the fixing support 6 is installed with the door panel metal plate 9 and the door and window chrome plating strip 13. The light guide shell 1 is fixedly provided with a light emitting module 8, the light emitting module 8 comprises an upper circuit board 51 and a lower circuit board 52, the upper circuit board 51 is provided with a plurality of upper LED light sources 2, and the lower circuit board 52 is provided with a plurality of lower LED light sources 3.

The light guide shell 1 is composed of a diffusion part 11 for homogenizing light at the light outlet of the side beacon light and a transparent light guide part 12 fixed with the LED light-emitting module. The material of the diffusing material part 11 may be diffusing injection molded particles, or a diffusing agent added to the transparent material, or may be composed of a transparent part coating film. The transparent light guide part 12 is made of transparent PC or PMMA. The two parts form the light guide shell 1 through double-color injection molding or sticking.

As shown in FIG. 4, the thickness of the diffuser portion 11 is 1.5mm to 8mm (r). The width of the light outlet is at least 1.2mm (phi). Different optical uniformity effects can be provided by adjusting the thickness of the bulk material. The distances between the light incident surface 10 of the transparent light guide part 12 and the upper LED light source 2 and the lower LED light source 3 are both 0.5-3mm (c).

The light propagation direction 7 of the light guiding housing is: the light emitted by the LED light source firstly enters the transparent light guide part 12, is subjected to efficient total reflection propagation in the transparent material, and further enters the diffusion material part 11, and the diffusion material can perform effective diffusion action on the light, so that the light emitted by the light outlet is uniform in brightness.

As shown in fig. 5, the color of the light emitted by the upper LED light source 2 satisfies the side marker light regulation. The lower LED light source 3 is an RGB light source which meets the effect of the atmosphere lamp under different working conditions. The two LED light sources are uniformly arranged on the circuit board at intervals, and the distance between the upper LED light sources 2 and the distance between the lower LED light sources 3 are both 5-50mm (r). Under the condition of ensuring the height consistency of the light-emitting center lines of the upper LED light source and the lower LED light source. The positions of the upper LED light source and the lower LED light source can be interchanged.

The upper circuit board 51 and the lower circuit board 52 are wirelessly connected with a vehicle body terminal LIN, CAN or using 4G/5G. The LED light source is controlled by a vehicle body end LIN, a CAN or a 4G/5G, and the LED light source is controlled to have different static or dynamic effects according to different use scenes.

The length of the side marker lamp is increased to 800mm, so that the identifiability and the safety of the vehicle in the running process are improved. Meanwhile, the RGB atmosphere lamp effect is increased on the basis of the function of the traditional side marker lamp, man-machine interaction can be carried out under different working conditions (such as locking and unlocking of a vehicle, opening of a vehicle door, automatic driving of the vehicle, charging of the vehicle and the like), sensory stimulation is enhanced, and the grade of the whole vehicle is improved.
