High-power LED mining lamp

Abstract

The invention provides a high-power LED mining lamp. The high-power LED mining lamp comprises an LED light source, a uniform temperature board and a heat sink, wherein the LED light source is attached to the bottom face of the uniform temperature board; the heat sink is attached to the top face of the uniform temperature board; a chimney is arranged on the heat sink. The high-power LED mining lamp has the beneficial effect that the heat dissipation capacity of the heat sink and the heat dissipation efficiency can be greatly improved through the chimney.

Description

technical field [0001] The invention relates to a lighting device, in particular to a high-power LED industrial and mining lamp in the lighting device. Background technique [0002] The accelerated promotion of energy saving and emission reduction, as well as the large-scale application of lighting-level LEDs, have given birth to the development of LEDs in professional fields, especially the application research of surface-mounted LEDs with low thermal resistance, high luminous efficiency, and high cost performance under the condition of area permits, which has broken through the LED industrial and mining industry. The lamp itself has the limitation that only COB light sources can be used. [0003] Every time the temperature of electronic products rises by 10 degrees, the lifespan will be reduced by 50%. LEDs are heat-sensitive optoelectronic products, which is also suitable for just theory, which is equivalent to a 50% reduction in LED lifespan. In order to solve the probl...

Problems solved by technology

[0004] At present, the Chinese invention patent No. 201310045872.5, named "a high bay lamp", uses ADC12 as the conical die-casting part as the heat sink. In order to make up for the poor heat dissipation performance of the ADC12 material, the heat sink is designed in the form of reinforcing ribs. The mountain-shaped and U-shaped transparent structure, in order to change the direction of the light, the light source uses SMD to focus on the surface of a small aluminum substrate, forming an essentially COB-like light source, which causes the center temperature of the light source to remain high, and at the same time Due to the small lateral area of ​​the ribs reduces the heat conduction capacity, it will inevitably lead to serious light decay of the lamps; An integrated LED with a small power can slightly improve the life of the LED high bay lamp, but it cannot change the current situation of the high center temperature of the integrated LED and the short lifespan; for example, the Chinese invention patent No. 201010558368.1, the name is "an integral LED high bay lamp with efficient heat dissipation ", the display LED is directly welded on the surface of the radiator, which reduces the thermal resistance of the LED heat transfer path, and also improves the problem of high center temperature and short life of the COB LED. However, when a certain LED of the lamp is defective, maintenance is required At this time, because the LED is directly welded on the surface of the radiator, it is impossible to locally heat the LED welding position to replace the defective LED, and the entire LED industrial and mining lamp can only be scrapped, resulting in a serious waste of resources, a serious increase in user costs, and a straight-line after-sales cost for enterprises. rise
