Problems solved by technology

[0003] Existing LED lamps need to add a light-diffusing cover to expand the light when expanding the light. The existing light-diffusing cover is not effective in expanding the LED light, and its luminous flux and color temperature are unstable. At the same time, the heat dissipation of the existing LED lights is mostly Larger aluminum block is used for heat dissipation, more materials are used and the cost is higher

Abstract

The invention relates to a light diffusion light-emitting diode (LED) lamp, which aims at solving the problems that the effect is not good, the luminous flux and the color temperature are not stable when the existing light diffusion cover diffuses light of the LED lamp; and since aluminum blocks are mostly used for the radiation of the existing LED lamp, the amount of the used materials is large and the cost is high. The light diffusion LED lamp mainly comprises an LED blue light chip and a transparent light guide column, wherein an enclosing wall which is made of a light reflecting and heat conducting material is arranged on the substrate of the LED blue light chip, the chip is arranged in the enclosing wall and the upper surface of the substrate in the enclosing wall is covered with a transparent heat conducting layer; and a cover plate is arranged at the lower part of the transparent light guide column, step slots which are matched with the LED blue light chip are arranged on the bottom surface of the cover plate, light reflecting layers are arranged on the side wall of a second step slot and the upper surface of the cover plate, a fluorescent layer is arranged on the top surface of the second step slot and a light reflecting structure is arranged at the top of the transparent light guide column. The light diffusion LED lamp has the advantages that the light distribution effect of different curves can be realized, the stability of the luminous flux, color temperature and electric parameters of the entire system is improved, the light attenuation is reduced and the luminous flux maintenance factor is improved.

Description

technical field [0001] The invention belongs to a lighting device, in particular to a light-diffusing LED lamp. Background technique [0002] LED lights use light-emitting diodes to emit light. It is a solid-state semiconductor device that converts electricity directly into light. It has the characteristics of high luminous efficiency, low power consumption, long life, easy control, maintenance-free, safety and environmental protection, and is widely used. [0003] Existing LED lamps need to add a light-diffusing cover to expand the light when expanding the light. The existing light-diffusing cover is not effective in expanding the LED light, and its luminous flux and color temperature are unstable. At the same time, the heat dissipation of the existing LED lights is mostly Using a larger aluminum block for heat dissipation requires more materials and higher cost. Contents of the invention [0004] The object of the present invention is to solve the above-mentioned probl...
