High-power light-emitting diode (LED) street lamp

Abstract

The invention discloses a high-power LED street lamp. The street lamp comprises a lamp holder, a lamp shade, a drive controller and a plurality of LED lamps. The plurality of LED lamps are arranged in the front of the lamp holder in a rectangular array structure, the lamp shade is packaged in the front of the lamp holder, and a transparent glass window corresponding to the LED lamps is arranged on the lamp shade. A plurality of fin-shaped metal cooling sheets perpendicular to the lamp holder are arranged at the back of the lamp holder, and the drive controller is fixedly connected onto the metal cooling sheets and is connected with the LED lamps. Light is irradiated outwards by the plurality of LED lamps through the transparent glass window, the irradiation luminance is high, the LED lamps are applicable to the street lamp and matched with the metal cooling fins integrated with the lamp holder mounted with the LED lamps to performing cooling outwards, high-power luminance and cooling effects can be combined effectively, damage caused by long-time high-power working heating of the street lamp is prevented, and the LED street lamp is simple in structure, convenient to manufacture, high in lighting effect and long in service life.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a high-power LED street lamp. Background technique [0002] LED is a semiconductor that can convert electrical energy into light energy. It changes the principle of tungsten filament luminescence of incandescent lamps and the three-based toner luminescence of energy-saving lamps, and uses electric field luminescence. Existing LEDs are used in street lamps, which have the characteristics of long life, high luminous efficiency, low radiation and low power consumption. However, street lamps ensure high lighting brightness, and the lighting brightness of a single LED lamp cannot meet the requirements, which must be achieved by increasing the number of LED lamps. To achieve, simply arrange multiple high-power LED lamps on the street lamps, which generate a large amount of heat. If the heat cannot be effectively dissipated, it will easily affect the service life of the street lamps. Contents of the inv...
