High-power forced water-cooling light-emitting diode (LED) street lamp

Abstract

The invention discloses a high-power forced water-cooling light-emitting diode (LED) street lamp. The street lamp comprises an arched waterway heat dissipating device shell body, a square waterway heat dissipating device shell body is arranged below the arched waterway heat dissipating device shell body, front flow passage covers are arranged at the front ends of the arched waterway heat dissipating device shell body and the square waterway heat dissipating device shell body, rear flow passage covers are arranged at the rear ends of the arched waterway heat dissipating device shell body and the square waterway heat dissipating device shell body, the front flow passage covers and the rear flow passage covers are communicated through water pipes, water pumps are arranged in the water pipes, the front ends of the front flow passage covers are provided with front end covers, the rear ends of the rear flow passage covers are provided with rear upper end covers and rear lower end covers, adjustable bases and driving power supplies are arranged on the rear lower end covers, the square waterway heat dissipating device shell body is arranged above glass, an alumina-based circuit board is arranged between the square waterway heat dissipating device shell body and the glass, a reflector is arranged on the lower portion of a pressing strip of the alumina-based circuit board, a double-side luminous lens is arranged on the lower portion of the reflector, and the double-side luminous lens is connected with the glass. The high-power forced water-cooling LED street lamp has the advantages of being good in the sealing and heat dissipation.

Description

technical field [0001] The invention provides a road lighting lamp, especially a high-power forced water-cooled LED street lamp, which belongs to the field of road lighting manufacturing. Background technique [0002] Street lights are generally used for road lighting, and high-power LED street lights will become the direction of road lighting in the future due to their advantages in energy saving, environmental protection, and long service life. At present, the luminous efficiency of high-power LED street lamps is generally only 15% to 30%, and most of the remaining energy is converted into heat energy. If this part of heat energy cannot be effectively discharged, the service life of the lamps will be shortened, while the existing high-power LED Street lamps generally use natural air cooling or forced air cooling for heat dissipation. The disadvantages are that they are highly dependent on environmental conditions and have low heat dissipation efficiency, so they cannot eff...

Problems solved by technology

At present, the luminous efficiency of high-power LED street lamps is generally only 15% to 30%, and most of the remaining energy is converted into heat energy. If this part of heat energy cannot be effectively discharged, the service life of the lamps will be shortened, while the existing high-power LED Street lamps generally use natural air cooling or forced air cooling for heat dissipation. The disadvantages are that they are highly dependent on environmental conditions and have low heat dissipation efficiency, so they cannot effectively meet the heat dissipation requirements of high-power LED street lights.
