LED lighting for outdoor use

Abstract

The invention discloses an outdoor LED illuminating lamp, which comprises a base, on which a left strut and a right strut are arranged side by side, and a lamp shell is arranged between the left strut and the right strut, inside the lamp shell A light-emitting circuit board is provided, and a plurality of LED lamp beads are arranged on the light-emitting circuit board, and a light-transmitting cover is provided at the light outlet of the lamp housing; a plurality of first horizontal fins are arranged on the light-emitting circuit board, There are a plurality of second horizontal fins inside the lamp housing; a slider is slidably connected between the two first horizontal fins; a screw rod is connected to the lamp housing in rotation, and the screw rod is screwed to the slider, and the The left end of the screw rod is equipped with a left gear, the right end is provided with a right gear, the left rack is provided in the left vertical chute, and the right rack is provided in the right vertical chute; the slide block inside the lamp housing There is a dust removal component on the top; the outdoor LED lighting is not only simple in structure, small in size, but also easy to store, and can clear the dust on the cooling fins 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
