Abstract

The invention relates to LED illumination lamps, in particular to a forced-cooling high-power LED lamp. The forced-cooling high-power LED lamp comprises a lamp shell, an air inlet area, a heat dissipation area and an air exhaust area, and the air inlet area, the heat dissipation area and the air exhaust area are assembled in the lamp shell. An air inlet separation plate is arranged between the air inlet area and the heat dissipation area, and air inlet separation plate air guide holes are formed in the air inlet separation plate. An air exhaust separation plate is arranged between the heat dissipation area and the air exhaust area, and air exhaust separation plate air guide holes are formed in the air exhaust separation plate. The forced-cooling high-power LED lamp has the advantages of being high in power, light, high in light efficiency, low in junction temperature, high in energy efficiency, low in cost, free of maintenance and capable of being intelligently controlled.

Description

technical field [0001] The invention relates to an LED lighting lamp, in particular to a forced heat dissipation high-power LED lamp. Background technique [0002] LED has the characteristics of unidirectional light emission, low power consumption, and long life, and is the most promising alternative light source for road lighting or other gas light sources. Traditional gas lights due to 360 0 Luminous, resulting in more than 50% of energy waste. If the maturity of LED street lamps can reach the technical level of traditional high-pressure sodium lamps, using equal-illuminance LED street lamps to replace high-pressure sodium lamps will save electricity by more than 60%, and the economic benefits are very significant. [0003] The electricity-to-light conversion rate of LED is about 25%, and the remaining electricity is converted into heat energy. If the heat cannot be conducted out at an extremely fast speed, it will cause the junction temperature to be too high and cause...
