At present, a rear steering lamp adopts a thick-wall light guide mode, an LED light source is mostly arranged right behind the thick-wall light guide, light rays irradiate forwards, and the purpose of uniform light emitting is achieved through mixing of the thick-wall light guide. In a lighting state, because the light emitting angle of the LED light source is generally not more than 120 degrees, the light intensity of an area outside the light emitting range is small, the central brightness is high, and the periphery is dark. Meanwhile, in the unlighted state, the yellow fluorescent powder part of the LED light source can be observed through the transparent thick-wall light guide, so that the appearance effect is poor.
The transparent feel and abundant lines of thick wall light guide change, can express the banding luminous effect that has the degree of distinguishing after lighting, can demonstrate the glittering and translucent molding effect inside the car light under the non-lighting state, and each whole car factory adopts LED light source + thick wall light guide optics scheme more and more on the function of back indicator. In a traditional thick-wall light guide scheme, an LED light source is generally arranged right behind a thick-wall light guide, obvious granular feeling is easy to appear after the LED light source is lightened, and internal appearance defects are easy to appear through a transparent thick-wall light guide when the LED light source is not lightened.
