Embodiment Construction

[0032] The present invention will be described in further detail below.

[0033] An integrated high-power LED industrial and mining lamp based on phase change heat transfer technology, including a COB light source, an evaporating plate, and a radiator connected sequentially from bottom to top, and also includes a cavity connected between the evaporating plate and the radiator. Liquid column. The radiator, liquid filling column and evaporating plate are welded to form a whole, and the cavity formed by the base of the radiator and the evaporating plate is evacuated and filled with working fluid through the liquid filling column, and then sealed; then the COB light source is pasted on the The lower surface of the evaporation plate.

[0034] The radiator is extruded first, and there are many vertical fins on it. The fins are rectangular and evenly distributed on the base of the radiator. The fins are parallel to each other with a certain gap. The thickness of the base is 2mm.

Abstract

The invention relates to an integrated type high-power LED lamp for industrial use based on a phase-change heat transfer technology. The integrated type high-power LED lamp for the industrial use comprises a COB light source, an evaporation plate and a radiator which are sequentially connected from bottom to top; the upper end of the evaporation plate and the lower end of the radiator define a vacuumized containing cavity, and the containing cavity is internally filled with a liquid working medium; and liquid absorption cores with one micro-groove-shaped surfaces are arranged at the upper end and the lower end of the interior of the containing cavity separately. The integrated type high-power LED lamp for the industrial use is compact in structure, small in size, light in weight, capable of meeting high-power illumination and fast in radiating, and relates to the technical field of LED lamp radiating.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of LED lamps, in particular to an integrated high-power LED industrial and mining lamp based on phase change heat transfer technology. Background technique [0002] As the fourth-generation light source, Light emitting diode (LED) has the advantages of energy saving, environmental protection, long life, and adjustable brightness and color temperature. With the maturity of LED technology and the continuous improvement of efficiency, LED solid-state lighting is the trend and the best solution for energy saving in the lighting industry. However, with the wide application of LED high bay lights and the need for lighting intensity, people have put forward higher requirements for their power. The power does not increase, making the heat dissipation enhancement of LED high bay lights a factor that must be considered to ensure the quality of its products. If the heat cannot be effectively condu...
