Large-power LED combined lamp

Abstract

The invention relates to a large-power LED combined lamp which comprises a cooling shell, a lens and a light source. The cooling shell is sequentially provided with a center cooling unit and a lamp shell cooling unit from front to back; the back of the lamp shell cooling unit is connected with a rear cover; a power supply cooling unit which is connected with the rear cover is arranged in the lampshell cooling unit; the front part of the center cooling unit is provided with a empty cavity for holding the light source and the center of the center cooling unit is provided with a cooling hole which can communicate the empty cavity with the power supply cooling unit; and a plurality of cooling fins are evenly arranged on the back side of the lamp shell cooling unit along the circumferential direction. In the invention, by adopting the combination of a plurality of cooling units, the outside lamp shell functions as both a shell and a cooling unit, and thus, the lamp can be combined with a large-power LED light source and can meet the requirement of an LED on quick cooling and greatly improve the luminous decay, the service life and the like of the LED.

Description

(1) Technical field [0001] The invention relates to a high-power LED combination lamp. (2) Background technology [0002] For thousands of years, human beings have been chasing light. From ancient times——drilling wood to make fire, kerosene lamps, to incandescent light bulbs invented by Edison, fluorescent lamps invented by Claude, step by step, human beings are pursuing more efficient and durable lighting method. Entering the 21st century, people will pay more attention to energy saving and environmental protection. The emergence of high-power LED (light-emitting-diode) semiconductor light-emitting devices as the light source has become another revolution in the history of human lighting. It is gradually replacing traditional lighting and entering the LED era. All countries in the world are focusing on the LED market. , and my country also launched the "National Semiconductor Lighting Project" with a huge investment in June 2003. Therefore, its application faces great mar...

AI Technical Summary

Problems solved by technology

The heat dissipation effect and light utilization efficiency are extremely low, and the most basic lamp protection level cannot reach

Although the latter has been independently designed, due to tight protection requirements, the LED light source and power supply are in a sealed space at the same time, and the heat emitted by the two devices intersects with each other, which seriously affects the heat dissipation requirements of the LED light source. , the internal temperature becomes too high, which accelerates the light decay of the light source and the service life of the power supply

At the same time, in terms of maintenance, because the power supply part, radiator and lamp housing are a whole, it is extremely inconvenient to replace and other defects, which affects the use effect and fails to meet the simple requirements
