Large-power LED (light-emitting diode) streetlamp

Abstract

The invention discloses a large-power LED (light-emitting diode) streetlamp which comprises a radiating base, wherein at least three LED lamps which are connected are embedded into the concave bottom surface of the radiating base; the periphery of the notch of the radiating base is assembled with a light transmission cover; the outer part corresponding to the concave bottom surface of the radiating base is provided with a conditioned radiating body with a special design; LED lamp heads are in sleeving connection with corresponding lenses; a lens fixing cover plate is clamped between the radiating base and the light transmission cover; the lens fixing cover plate is provided with lens holes which are corresponding to the LED lamps in number; and the end parts of the lenses are embedded into the corresponding lens holes. The large-power LED streetlamp is energy-saving and is delicate in model; a main body model is manufactured from materials such as excellent plastic, a glass aluminum material and the like; and the large-power LED streetlamp has an active protection function, and has the characteristics of being wide in scope of application, remarkable in power-saving effect, relatively low in price, and the like.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a high-power LED street lamp with good heat dissipation performance. Background technique [0002] The street lights used on the road are all 150W-400W, and the power source of the lighting is usually a large amount of power consumption. Because the general street lights require a large amount of power supply, it brings a lot of pressure to energy consumption, and can only It can only be used normally when the power supply is sufficient. At the same time, in practical applications, for the sake of saving electricity, the brightness of the street lights needs to be adjusted at different time periods. Electricity. However, ordinary street lamps use ordinary fluorescent lamps or sodium lamps. In order to reduce the brightness, they can only be made to work at a state lower than the rated power, and these lamps are easily damaged when they work in an abnormal working state lower than their r...

AI Technical Summary

Problems solved by technology

However, the existing LED lights do not adopt a cooling component structure with good heat dissipation performance, and the LED lights can still be used normally when the power is small. When the power of the LED lights is high, the heat emitted by the LED lights cannot be dissipated well, resulting in damage to the LED lights. , affecting people's normal use
