Starry sky pattern rear position lamp

Abstract

The invention relates to a starry sky pattern rear position lamp which is composed of an LED light source, a circuit board assembly, an installation support, a starry sky pattern additional mask, a decoration ring, an outer mask and a shell. Light rays emitted by the LED light source directly irradiate the starry sky pattern additional mask, are refracted through polygonal patterns on the starry sky pattern additional mask to form a light type meeting the light distribution requirement of the position lamp, and are emitted through the starry sky pattern additional mask and the outer mask in sequence. The random starry sky patterns are generated on the upper portion of the transparent additional mask for rear position lamp light distribution, light rays can be refracted when passing through the random starry sky pattern additional mask, the refraction angle is random, the light rays refracted by the triangular surfaces at different positions can enter the human eyes along with movement of the human eyes, and therefore the starry sky light-emitting effect is formed; and plane uniform light emitting and three-dimensional uniform light emitting are achieved, the light source cost of the rear position lamp can be reduced, and starry sky patterns are improved to the maximum degree in combination with the rhythm light emitting effect of the rear position lamp.

Description

technical field [0001] The invention belongs to the technical field of automobile interior decoration, and in particular relates to a starry sky pattern rear position lamp. Background technique [0002] At present, rear taillights on the market have widely adopted uniform light emitting technology, which is more common in rear position lights, but the static and lighting appearance effects of most rear position lights are relatively simple, mostly point-shaped or strip-shaped light-emitting effects, structural forms More traditional, quite satisfactory, lack of artistic sense and innovation. [0003] The prior art discloses a car rear position lamp with 3D depth of field effect. It includes a plurality of PCB boards arranged at intervals along the transverse direction; the PCB boards are arranged horizontally along the longitudinal direction, and each PCB board is arranged with a plurality of LED lamp groups formed by LED lamps arranged at intervals along the longitudinal d...
