Description

Structure for realizing uniformity of position lamp by utilizing double-color structure multiple reflection Technical Field The utility model relates to the technical field of automobile lamps, in particular to a structure for realizing uniformity of a position lamp by utilizing multiple reflection of a double-color structure. Background At present, in the technical field of automobile lamps, the effect of uniformity of a position lamp is mainly achieved through the following types of (1) an LED+a reflector+a double-color thick-wall member and (2) an LED+a condenser+a double-color thick-wall member, wherein the type I is in a form that LED light is converted into parallel light through the reflector, and the parallel light passes through a light guide surface diffusion material of the thick-wall member so as to achieve the requirement of uniform lighting of the position lamp. For example, the patent with publication No. CN111561683a discloses a "high-efficiency high-uniformity automobile position lamp arrangement structure", which adopts a mode of led+reflector+thick-wall light guide plate, designs all strip-shaped lamp strip light emitting surfaces on an automobile lamp as a thick-wall light guide, the thick-wall light guide adopts diffusion PC material and diffusion PMMA material, then a reflective bowl is arranged on the back surface of the thick-wall light guide, PCB and LED are arranged above or below the reflective bowl, when the LED is lighted, light is converted into parallel light through the reflective bowl, then the parallel light passes through diffusion material of the thick-wall light guide surface, so as to realize improvement of uniformity of light. For example, patent publication No. CN109340697a discloses a "condenser optical system for a vehicle lamp with a light curtain effect", which adopts a structure of led+condenser+bicolor thick-wall member, a part of light emitted from an LED light source becomes quasi-parallel light after passing through the condenser, and enters a transparent part of bicolor injection-molded thick-wall member and passes through a pattern area, thereby deriving a pattern lighting effect, another part leaks out through an upper surface of the condenser, enters a scattering material part of bicolor injection-molded thick-wall member, and finally derives a light curtain lighting effect through a light curtain area of the transparent part of bicolor injection-molded thick-wall member, thereby improving lighting uniformity of the pattern area. The scheme can improve the uniformity of light to a certain extent, but can further improve the uniformity.
