Spreadlight lens LED lamp

Abstract

The invention discloses a spreadlight lens LED lamp which comprises a substrate; a lens module which is connected with the substrate, wherein a containing space is formed between the substrate and the lens module, the lens module comprises at least one lens, and each lens module comprises an optical axis, a first free-form surface and a second free-form surface; and LED light sources which are arranged in the containing space and connected with the substrate, and the LED light sources and the lenses are arranged in a one-to-one correspondence mode. The first free-form surfaces and the second free-form surfaces are arranged on the lenses, and the LED light sources and the lenses are correspondingly arranged, so that light rays emitted by the LED light sources are refracted by the first free-form surfaces and then are emitted to the second free-form surfaces, and symmetrical emergent light spots with the semi-light intensity of 140 + / -5 degrees are formed after the light rays are refracted by the second free-form surfaces for the second time. Compare with a traditional low dome light, the spreadlight lens LED lamp has the advantages of being uniform in illumination, wide in irradiation range, high in energy utilization rate, capable of eliminating glare and safe and reliable to use.

Description

technical field [0001] The invention relates to the technical field of light distribution, in particular to a polarized lens LED lamp. Background technique [0002] In industrial lighting scenarios such as mine roadways, tunnels, and indoors, the lamps currently used are mainly traditional gas discharge lamps or metal halide lamps, and even energy-saving lamps containing mercury are used in some places. The low-ceiling lamps used in the above-mentioned areas have low illuminance and light pollution. [0003] Chinese patent CN101709847A, the patent name is "Light Distribution Lens", which discloses a light distribution lens, which includes a lens body with a concave center, and the inner and outer sides of the concave part are the light incident surface and the light exit surface respectively. The light-emitting surface is symmetrical about two mutually intersecting and perpendicular symmetry axes and is an aspheric surface type. The aspheric surface type follows the formula...

AI Technical Summary

Problems solved by technology

However, the disadvantage of this technology is that the control of the light angle of the light source is limited and it will be diffusely reflected to the sky and other directions, so that the light emitted by the light source is not sufficiently controlled and effectively used, resulting in glare and energy waste.

[0004] Therefore, it is necessary to provide a polarized lens with uniform illumination to solve the problems of glare and low energy utilization
