Abstract

The invention provides an optical reflector and an LED (Light-Emitting Diode) luminous element using the reflector. The optical reflector comprises a plurality of reflecting surfaces, a refracting surface and a bottom surface, wherein the refracting surface is partitioned into a plurality of tiny light-emitting surfaces; each tiny light-emitting surface has different curvatures and different normals.

Description

Technical field [0001] The present invention relates to optical lighting technology, and more specifically, to an optical reflecting device and an LED light-emitting element of a lamp body. Background technique [0002] From the perspective of application, car lights include headlights, night lights, fog lights, brake lights, tail lights, reversing lights, etc. The most important thing for vehicle safety is the headlights. Headlights refer to the headlights combined in the front of the car. Lamp, it mainly plays the role of illumination and signal. The light emitted by the headlights can illuminate the road conditions in front of the vehicle body, so that the driver can drive safely in the dark. At present, the combined headlights can be divided into halogen lamps and xenon lamps according to the light source. [0003] Halogen lamps are actually a special kind of incandescent lamps. The principle is that when a current flows through the resistor, it generates heat, and when the te...
