Efficient and high-heat-dissipation guide rail LED spot lamp

Abstract

The invention discloses an efficient and high-heat-dissipation guide rail LED spot lamp, and belongs to the technical field of guide rail spot lamps. The LED spot lamp comprises a lamp barrel, rectangular holes are arranged in the outer wall of the lamp barrel in an annular array manner, a lamp cap cover is in threaded screwing to the right end of the lamp barrel, inner teeth are arranged on the inner wall, close to the left side, of a heat dissipating barrel, the inner teeth are meshed with a transmission gear, a driving gear is horizontally meshed to the other side of the transmission gear,the front and rear ends of a fixing plate are fixed to the inner wall of the lamp barrel, an exhaust fan is arranged at the position, close to the left side, of an inner cavity of the lamp barrel, theright side of the exhaust fan is connected with a transmission shaft of the driving gear through a connecting shaft and a coupler, a heat dissipating net is arranged at the left end of the lamp barrel, a U-shaped hanging bracket is connected to the outer wall of the lamp barrel in a forward-backward rotation manner, a sliding block is rotatably connected to the bottom of the U-shaped hanging bracket, the heat dissipating barrel of the spot lamp is driven by a fan motor to rotate, while heat dissipation is carried out through rotation of arc-shaped blades, inclined holes suck in cold air whichthen forms convection with hot air exhausted by the exhaust fan, and thus the heat dissipation is efficient.

Description

technical field [0001] The invention relates to the technical field of guide rail spotlights, in particular to a guide rail LED spotlight with high efficiency and high heat dissipation. Background technique [0002] Because the LED track spotlight has the advantages of rich colors, environmental protection and energy saving, light and convenient, it is widely used, but the existing LED track spotlights also have some shortcomings, such as the relative sealing of the lamp body, resulting in the heat inside the lamp body It is difficult to dissipate it. In order to increase the heat dissipation effect, some people add a cooling fan to the lamp body. A single fan dissipates heat, without convective air flow, and the heat dissipation efficiency is low. To this end, we propose a high-efficiency and high-radiation guide rail LED spotlight. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency and high-radiation guide rail LED spo...
