Multifunctional LED lamp

Abstract

The invention discloses a multifunctional LED lamp. The multifunctional LED lamp comprises a lamp body, a metal cover and a lamp plate; the metal cover is composed of a top end metal ring and metal supporting pieces evenly connected between the top end metal ring and the lamp body, and a glass cover is arranged between the metal supporting pieces; the lamp plate is sequentially provided with a main light emitting unit, a first auxiliary light emitting unit and a second auxiliary light emitting unit from inside to outside; the main light emitting unit, the first auxiliary light emitting unit and the second auxiliary light emitting unit are each provided with a plurality of LED light sources; the positions, matched with the LED light sources, of the back side of the lamp plate are provided with cooling columns; a light guiding plate and a light diffusion plate are sequentially arranged on the light outgoing side of the LED light sources; and the lamp plate, the light guiding plate and the light diffusion plate are sequentially installed in the lamp body. According to the multifunctional LED lamp, the light intensity of an LED refrigeration house lamp can be increased or decreased by controlling the number of the light emitting units, the light guiding plate and the light diffusion plate are arranged on the light outgoing side of the LED light sources, dazzle light is effectively eliminated, and the temperature accumulation phenomenon on a center point of the lamp plate is eliminated through the cooling columns.

Description

technical field [0001] The invention belongs to the technical field of LEDs, in particular to a multifunctional LED lamp. 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 Brightness under power is 10 times that of incandescent lamps; [0004] 2. Long life: the life s...

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 causes the temperature at the center point of the lamp panel to accumulate. Easily damaged LED lights

And when the LED light fails, there is no spare or emergency lighting to replace it. When it is necessary to increase the intensity of the LED light, the existing LED is powerless

At the same time, the glare of the light source of the existing LED lamp is not handled properly, and people's eyes feel uncomfortable. Long-term use may also affect vision.
