Detailed Implementation

[0017] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0018] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a car headlight with a flexible light source, according to an embodiment of the present invention. Figure 2 This is an embodiment of the present utility model. Figure 1A cross-sectional view of the lamp cover 40 is shown in the figure. As shown, a car headlight with a flexible light source includes: a lamp housing 10, within which are arranged, from left to right, a position light chamber 11, a fog light chamber 12, a turn signal chamber 13, a brake light chamber 14, and a reversing light chamber 15. Reflector bowls 20 are provided within the position light chamber 11, fog light chamber 12, turn signal chamber 13, brake light chamber 14, and reversing light chamber 15. A microstructured light guide layer 30 is provided on the reflector bowl 20.

A lamp cover 40 is provided on the lamp housing 10, and a functional film layer 50 is provided inside the lamp cover 40. The functional film layer 50 includes a diffuse scattering film layer 60 disposed on the left side and a high-transmittance film layer 70 disposed on the right side of the diffuse scattering film layer 60.

[0019] In one embodiment of this utility model, the lamp housing 10 is provided with position light chamber 11, fog light chamber 12, turn signal chamber 13, brake light chamber 14, and reversing light chamber 15 arranged sequentially from left to right to house various types of lamps.
