Eye-protection LED lamp with good heat dissipation property

Abstract

The invention discloses an eye-protection LED lamp with the good heat dissipation property. The eye-protection LED lamp comprises a lamp body, a metal cover and a lamp panel. The metal cover is composed of a top metal ring and metal supporting parts uniformly connected between the top metal ring and the lamp body. A glass cover is arranged between the metal supporting parts. A plurality of LED light sources are arranged on the lamp panel. Heat dissipation columns are arranged in the positions, matched with the LED light sources, of the reverse side of the lamp panel. A light guide plate and a light diffusion plate are sequentially arranged on the light outgoing side of the LED light sources. The lamp panel, the light guide plate and the light diffusion plate are sequentially mounted in the lamp body. According to the eye-protection LED lamp, the heat dissipation columns are arranged in the positions, matched with the LED light sources, of the reverse side of the lamp panel; the phenomenon of temperature rising in the center point of the lamp panel is effectively eliminated; the light guide plate and the light diffusion plate are arranged on the light outgoing side of the LED light sources; dazzle light is effectively eliminated, and eyes can be protected.

Description

technical field [0001] The invention belongs to the technical field of LEDs, in particular to an eye-protecting LED lamp with good heat dissipation. Background technique [0002] LED is the abbreviation of light emitting diode in English. Its basic structure is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver or gold wires. , and then sealed with epoxy resin around to protect the internal core wire, and finally install the shell. Has the following advantages: [0003] 1. Energy saving: the energy consumption of white light LED is only 1 / 10 of incandescent lamp and 1 / 4 of that of energy-saving lamp; it adopts super bright and high-power LED light source, cooperates with high-efficiency power supply, and saves more than 80% of electricity than traditional incandescent lamp, the same The brightness under power is 10 times that of incandescent lamps; ...

AI Technical Summary

Problems solved by technology

However, the heat dissipation aluminum of the existing LED lamp adopts an integrated type, that is, the high-power LED lamp is welded on the aluminum base plate, and the whole aluminum base plate dissipates heat through an integrated heat sink. This heat dissipation structure leads to the accumulation of temperature at the center of the lamp panel. It is easy to damage the LED lamp; at the same time, the glare of the light source of the existing LED lamp is not handled properly, the human eyes feel uncomfortable, and it may affect vision after long-term use
