Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, the present embodiment provides an adaptive color-changing lens assembly, which includes a light source module 2, the light source module 2 includes a circuit board 21 and a plurality of pairs of lamp groups 22 disposed on the circuit board 21, each pair of lamp groups 22 includes a yellow LED221 and a white LED222, the total number of the lamp groups 22 is even, and the centers of all the yellow LEDs 221 and the white LEDs 222 of the lamp groups 22 are located on a straight line and are mirror-image-type with respect to the middle vertical plane of the central connecting line of the middle two lamp groups 22, for example, two pairs of lamp groups 22 are arranged: a. a yellow LED221, a white LED222, and a yellow LED221; white LED222, yellow LED221, white LED222. The yellow LED221 and the white LED222 are individually controlled to be turned on, and a lens module 3 is disposed on each lamp group 22.

In combination with the specific practical scene, the method further analyzes that only the yellow LED221 is turned on in rainy days or when fog is large, and the yellow LED221 irradiates to the front in a parallel beam mode after being gathered and refracted by the lens module 3, so that the illumination definition is ensured. Similarly, in non-rainy days, only two white LEDs 222 are turned on for illumination. The features of the embodiments of the present utility model will be described herein: the embodiment of the present utility model employs an even number of lamp groups 22, and each pair of lamp groups 22 includes a yellow LED221 and a white LED222, all the LEDs are on a horizontal straight line, and all the yellow LEDs 221 and white LEDs 222 of the lamp groups 22 are distributed and mirror-image with respect to the middle vertical plane of the central connecting line of the middle two lamp groups 22. The reason for the even number of lamp sets 22 and the mirror image distribution of all LEDs with respect to the central vertical plane of the central connection of the middle two lamp sets 22 will be explained here.

First, referring to fig. 3 and 4, it is assumed that there are two pairs of lamp groups 22, since each lamp group 22 has both a yellow LED221 and a white LED222, and that the yellow LED221 of one of the lamp groups 22 is on the left of the white LED222, the light spot of the white LED222 is left and the light spot of the yellow LED221 is right after the individual white LED222 or the yellow LED221 is refracted by the small lens 31 and the large lens 32; if the other lamp set 22 and the middle vertical plane of the central connecting line of the two lamp sets 22 are in mirror image distribution, the yellow light LED221 of the other lamp set 22 should be on the right side of the white light LED222, the light spot of the white light LED222 is right after passing through the small lens 31 and the refraction of the large lens 32, and the light spot of the yellow light LED221 is left; if the yellow LED221 or the white LED222 is turned on separately, the light spots of the two yellow LEDs 221 (or the white LED 222) are symmetrical after the light interference, and the light spots of the two lamp sets 22 are brighter in the middle and become darker to both sides. However, if the yellow LEDs 221 and the white LEDs 222 of the two lamp sets 22 are not distributed in mirror image about the central line of the two lamp sets 22, the final light spot still has a problem of left or right after the white LEDs 222 or the yellow LEDs 221 are turned on separately, and the brightness in the middle of the light spot becomes darker relative to the mirror image distribution, so that the lighting effect is affected.

Second, if the number of the lamp sets 22 is odd, there is a problem that the yellow LEDs 221 and the white LEDs 222 cannot be distributed in mirror image, and thus the light spots are left and right.

In short, it is ensured that all the LED lamps of the pairs (even pairs) of lamp groups 22 are positioned on a horizontal straight line, meanwhile, all the yellow LEDs 221 and the white LEDs 222 are distributed in a mirror image mode relative to the middle vertical plane of the central connecting line of the middle two lamp groups 22, scattered light is gathered into parallel light speed to irradiate the road surface through the lens module 3, and the white LEDs 222 or the yellow LEDs 221 can be independently controlled to be respectively suitable for illumination in non-rainy and foggy weather, so that the layering problem of the illumination areas of white light and yellow light is solved.

It should be understood that the small lens 31 has an effect of improving illumination intensity, and is used for transmitting light to the light incident surface of the whole large lens 32, and is irradiated to the road surface in parallel after being refracted by the large lens 32.

Referring to fig. 2 to 5, as a specific embodiment of the present utility model, the present utility model further includes a light shielding bracket 4, wherein the light shielding bracket 4 is fixed to the circuit board 21, and the light shielding bracket 4 has a light shielding portion 41, and the light shielding portion 41 is located between the small lens 31 and the large lens 32.

The light shielding bracket 4 is utilized to enable light rays to be emitted from the yellow LED221 or the white LED222 along the light path channel as far as possible to enter the large lens 32 through the small lens 31 and irradiate the road surface, so that the loss of the light rays in the transmission process is reduced, the light source brightness is protected, the light rays are better gathered, and the lighting effect is improved.
