Large-area illumination LED refrigeration house lamp with multiple luminous units

Abstract

The invention discloses a large-area lighting LED cold storage lamp with multiple light-emitting units, which includes a lamp body, a metal cover and a lamp panel. The metal cover is supported by a top metal ring and a metal evenly connected between the top metal ring and the lamp body. A glass cover is set between the metal supports; the lamp panel is set in the space formed by the glass cover and the lamp body, and the lamp panel is detachably installed on the lamp body; the lamp panel is sequentially provided with the main light-emitting unit from the inside to the outside , the first auxiliary light-emitting unit and the second auxiliary light-emitting unit, the main light-emitting unit, the first auxiliary light-emitting unit and the second auxiliary light-emitting unit are respectively provided with a plurality of LED light sources, and the position where the back of the lamp panel matches the LED light source is provided with Cooling column. The invention adopts LED lamps to replace fluorescent lamps and incandescent lamps, which are green and environmentally friendly; the back of the lamp panel is provided with a heat dissipation column at the position where the LED light source matches, which effectively eliminates the phenomenon of temperature accumulation at the center of the lamp panel; Adjustable light intensity, but also energy saving.

Description

Technical field [0001] The invention belongs to the field of LED technology, and particularly relates to a large-area illuminating LED cold storage lamp with a plurality of light-emitting units. Background technique [0002] LED is the abbreviation of English light emitting diode (light emitting diode), its basic structure is a piece of electroluminescent semiconductor material chip, cured on the bracket with silver glue or white glue, and then connected the chip and the circuit board with silver or gold wire , And then sealed with epoxy resin around to protect the inner 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 that of incandescent lamps and 1 / 4 of that of energy-saving lamps; the use of ultra-bright high-power LED light source and high-efficiency power supply can save more than 80% of electricity than traditional incandescent lamps, the same The brightness under po...

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. 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
