Outdoor waterproof energy-saving high-power LED illumination lamp

Abstract

The invention discloses an outdoor waterproof energy-saving high-power LED (Light Emitting Diode) illumination lamp and belongs to the field of lamps. The lamp comprises a lamp housing, a baffle, an LED drive plate, a luminous plate, LED chips, an upper lamp cover, a louver and a fan, wherein the fan is fixed to one side of the baffle through screws; the LED drive plate is fixed to the other side of the baffle through screws; the upper lamp cover is fixed to the lamp housing through screws; the LED chips are uniformly clung to the luminous plate; lenses are arranged on the LED chips; the surfaces of the chips are coated with waterproof heat-conducting glue; the lamp housing is made of heat conduction and transfer metal; the louver is arranged on the side surface of the lamp housing; waterproof breathable cloth is arranged on the louver; and the part of the drive plate connected with the lamp housing is coated with heat-conducting glue and waterproof glue. According to the lamp, a plurality of heat radiation modes are combined, so that the heat radiation efficiency is improved, the temperature in the lamp is more slowly increased and reduced to be less than 80 DEG C, the service life can be prolonged by 10-15%, and the luminous efficiency is improved by 10%.

Description

technical field [0001] The invention relates to a lighting device, in particular to an outdoor waterproof and energy-saving high-power LED lighting lamp, which belongs to the field of lamps. Background technique [0002] LED (Light Emitting Diode) is a solid-state semiconductor light-emitting diode that converts electrical energy into visible light, and directly and efficiently converts electricity into light. LED lighting is a lighting fixture made of the fourth-generation green light source LED. LED is called the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life, and small size. It can be widely used in various Various indications, displays, decorations, backlights, general lighting and urban night scenes and other fields, the application prospects are very broad. [0003] In 1998, Japan's Ministry of International Trade and Industry issued the first phase of the "21st Century Light Pl...

AI Technical Summary

Problems solved by technology

[0006] At present, the heat dissipation measures adopted by domestic LED lighting include: first, use heat sinks to increase the heat dissipation area for heat dissipation, use metal for heat dissipation, second, use thermal conductive glue or thermal resin, and third, use fans for heat dissipation. These measures are in the heat dissipation process. The heat in the lighting lamp has a certain heat dissipation effect, but it still cannot realize the rapid and effective cooling of the LED lighting lamp, especially it cannot meet the heat dissipation requirements of the high-power LED lighting lamp

[0007] In addition, when the existing LED lighting lamps are used for outdoor lighting, the waterproof measures are generally not good, and rainwater is easy to penetrate into the LED chips, which will affect the normal operation of the LED lighting lamps after a period of time and reduce the service life of the LED lighting lamps.
