Light reflecting cup of light-emitting diode (LED) lamp bank

Abstract

The invention belongs to the technical field of lighting products, and provides a light reflecting cup of an LED (light-emitting diode) lamp bank. Primary reflecting surfaces and secondary reflecting surfaces are arranged upwards on the front side and the back side of a longitudinally-arranged lamp bank mounting seat symmetrically; secondary parabolic surfaces are symmetrically arranged on the left side and the right side of the bottom of the lamp bank mounting seat; reflecting flat surfaces are respectively leftwards and rightwards arranged on the secondary reflecting surfaces on the front side and the back side of the lamp bank mounting seat and in smooth transition with the secondary parabolic surfaces by using circular arc surfaces; LED lamp mounting holes are formed a left inclined surface, a right inclined surface and an upper bottom surface of the lamp bank mounting seat; mounting and connecting lugs respectively extend frontwards and backwards from the front side and the back side of the upper bottom surface; a mounting hole is formed on each mounting and connecting lug; and the reflecting cup is integrally formed in a ship shape or a shoe-shaped ingot shape. Due to the structural characteristics, the light reflecting cup has the advantages of simple structure, small formed light spot, high light source utilization rate, low cost, and the like.

Description

technical field [0001] The invention belongs to the technical field of lighting products, in particular to a reflective cup for an LED lamp group. Background technique [0002] At present, during the use of some lamps, especially LED lamps, the light emitted by the light source that cannot be illuminated on the work and living surfaces is reflected by the secondary light distribution technology of the existing reflector cup, which can greatly improve the light emission of the lamp. The utilization rate of the lamps greatly improves the working efficiency of the lamps, but the existing reflectors are relatively difficult to control the light. Generally, there is a reflective plane on the inside of the reflectors, which is difficult to achieve the actual lighting distribution requirements and the effective use of the total luminous flux of the lamps. The efficiency is not high enough, the formed spot is large, and the lighting effect is not ideal. Contents of the invention ...
