Embodiment Construction

[0014] refer to figure 1 , the present invention proposes a light-transmitting cover for LED vehicle lights, the outer surface of which is a partially spherical surface protruding outward, and the inner surface of the light-transmitting cover is a concave structure composed of multiple planes. The light source of the LED car light is composed of multiple LED lights, so the light emitted by the LED car light source is similar to parallel light. According to the principle of light refraction, through the double refraction of the inner surface and the outer surface, the angle of the light projected from the outer surface can be adjusted by adjusting the angle between each plane on the inner surface and the axis of the outer surface, so as to controlly scatter the light.

[0015] In this embodiment, a center plane perpendicular to the center line of the outer surface is provided at the center of the inner surface. The center plane, after passing through the center plane, the light...

Abstract

The invention discloses a light transmitting cover for an LED lamp. The outer surface of the light transmitting cover is part of the spherical face protruding outwards; and the inner surface of the light transmitting cover is a concave face structure composed of multiple planes. According to the light transmitting cover for the LED lamp, according to the principle of light refraction, due to the dual refraction of the inner surface and the outer surface, the angle of light ray projected out of the outer surface is adjusted by adjusting the included angles between various planes on the inner surface and the axis of the outer surface, and therefore controllable scattering is performed on the light ray.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a translucent cover for an LED vehicle lamp. Background technique [0002] Car lights are essential accessories for cars. Car lights play a role in early warning of vehicle actions during the day, and combine multiple functions of lighting and early warning at night. At present, most of the car lights use LED lights to simulate the illumination of plain light. However, LED car lights cannot completely realize parallel light, so that problems such as glare of car lights and limited field of vision caused by light convergence cannot be completely eliminated. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a transparent cover for LED vehicle lights. [0004] The present invention proposes a light-transmitting cover for LED vehicle lights. The outer surface of the light-transmitting cover ...
