Outdoor high-power LED lamp with efficient heat dissipation and high uniform light

Abstract

The invention discloses an outdoor high-power LED lamp with efficient heat dissipation and high uniform light. The outdoor high-power LED lamp with the efficient heat dissipation and high uniform light comprises a top cover, a hook, a heat dissipation piece, a light shield plate and a lampshade; the hook is arranged at the top of the top cover, and a plurality of air holes are formed in the top cover; a driving piece, a rotating speed controller and a main control chip are arranged in the top cover; the heat dissipation piece is arranged at the bottom of the top cover, and a plurality heat dissipation fins are arranged at the exterior of the heat dissipation piece; a protective sleeve is arranged in the heat dissipation piece; bayonet locks are arranged on two sides of the protective sleeve, and a connector is arranged at the top of the protective sleeve; heat sink is arranged at the bottom of the protective sleeve, and the upper part of the protective sleeve is cylindrical and extendsinto the protective sleeve; a gasket is arranged at the bottom of the heat sink, an LED driving chip is mounted at the bottom of the gasket, and a temperature sensor is arranged on the LED driving chip; and the light shield plate is arrange at the bottom of the heat dissipation piece. According to the outdoor high-power LED lamp with the efficient heat dissipation and high uniform light, the heatdissipation piece is driven to rotate by a driving piece to achieve the purpose of quick heat dissipation, and the problems proposed in the background technology are solved.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an outdoor high-power LED lamp with high-efficiency heat dissipation and high light uniformity. Background technique [0002] In the field of LED application, often only the luminous intensity of LED is emphasized, but the problem of LED service life is not solved. LED luminescence is generated by the transition of electrons between energy bands, and its spectrum does not contain infrared parts. The heat of LEDs cannot be dissipated by thermal radiation, so LEDs are "cold" light sources. At present, the luminous efficiency of LED can only reach 10%-20%, that is to say, 80%-90% of the energy is converted into heat energy. If the heat of the LED chip cannot be dissipated, the aging of the chip will be accelerated, and it may Lead to melting of the solder, making the chip invalid. So the temperature of the chip cannot exceed 125 degrees Celsius. However, in the harsh outdoor na...
