Outdoor LED illuminating lamp

Abstract

The invention discloses an outdoor LED illuminating lamp. The outdoor LED illuminating lamp comprises a base, a left supporting rod and a right supporting rod are arranged on the base side by side, alamp shell is arranged between the left supporting rod and the right supporting rod, a light-emitting circuit board is arranged in the lamp shell, a plurality of LED lamp beads are arranged on the light-emitting circuit board, a light-transmitting cover is arranged at a light outlet of the lamp shell, a plurality of first horizontal fins are arranged on the light-emitting circuit board, a plurality of second horizontal fins are arranged in the lamp shell, a sliding block is connected between the two first horizontal fins in a sliding manner, a lead screw is rotationally connected in the lamp shell and is in threaded connection with the sliding block, a left gear is installed at the left end of the lead screw, a right gear is arranged at the right end of the lead screw, a left rack is arranged in a left vertical sliding groove, a right rack is arranged in a right vertical sliding groove, and an ash removal assembly is arranged on the sliding block in the lamp shell. The outdoor LED illuminating lamp is simple in structure, small in size and convenient to store, and meanwhile accumulated dust on the cooling fins can be removed in time.

Description

technical field [0001] The invention belongs to the technical field of lighting lamps, and in particular relates to an outdoor LED lighting lamp. Background technique [0002] Outdoor LED lighting is mainly floodlights, also known as spotlights. Usually, it can be aimed at any direction and has a structure that is not affected by weather conditions. It is mainly used in large-scale mines, construction sites, etc.; A light lamp generally includes a lamp housing, a light-emitting circuit board arranged in the lamp housing, a plurality of LED light sources connected to the light-emitting circuit board, a switch, a power supply, a bracket, and the like. Wherein, the front of the lamp housing is often provided with a light-transmitting hole. When the power is turned on, the light emitted by the LED light source is irradiated from the front of the lamp housing to form a lighting area. For details, you can also refer to Chinese patents: ZL200620101929.4, ZL200720067802.X. The powe...

Problems solved by technology

For details, you can also refer to Chinese patents: ZL200620101929.4, ZL200720067802.X. The power of LED lighting is generally relatively large, so heat dissipation has a greater impact on the life of the lighting. In order to improve the heat dissipation effect of existing LED lighting, in the light-emitting circuit There are usually heat dissipation fins on the board. However, due to the large amount of dust in outdoor large-scale operations such as mines and construction sites, a large amount of dust will be absorbed on the heat dissipation fins. If they are not cleaned in time, the heat generated by the LED lighting will not be able to Scattered, seriously affecting the service life of LED lights
