Problems solved by technology

The release of photon energy itself will generate a lot of heat, which must be dissipated, otherwise it will affect the light emission of photons, increase the speed of light decay, reduce light efficiency, and significantly shorten the service life
The heating problem of LED light source has become a bottleneck restricting the development of LED explosion-proof lamps

Embodiment Construction

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] Such as figure 1 As shown, a water circulation heat dissipation housing for LED explosion-proof lamps includes an LED light source cavity (1), a large water storage chamber (4), a small water storage chamber (2) and a water storage chamber cover (5). The LED light source cavity (1) is fixed at the center of the shell with screws, the small water storage chamber (2) is arranged outside the LED light source cavity (1), and the large water storage chamber (4) is arranged at the Describe the outside of the small water storage chamber (2).

[0013] In this embodiment, the large water storage chamber (4) and the small water storage chamber (2) are connected by a spiral stainless steel pipe (3).

[0014] When the LED light source in the LED light source cavity (1) is working, the temperature rises naturally, and the raised temperature dissipates heat through conduction...

Abstract

The invention relates to a water-circulating cooling shell for an LED explosion-proof lamp. The water-circulating cooling shell comprises an LED light source cavity, a large water storage chamber, a small water storage chamber and a water storage chamber cover, the LED light source cavity is fixed at the center of the shell through bolts, the small water storage chamber is arranged on the outer side of the LED light source cavity, the large water storage chamber is arranged on the outer side of the small water storage chamber, and the large water storage chamber and the small water storage chamber are connected through a spiral stainless steel tube. The water-circulating cooling shell is power saving and environmental friendly, temperature of LED light sources can be effectively lowered, light failure speed can be slowed, and service life of the LED light sources can be guaranteed.

Description

technical field [0001] The invention relates to an LED explosion-proof lamp, in particular to a water circulation heat dissipation shell for the LED explosion-proof lamp. Background technique [0002] LED light sources use semiconductor chips as luminescent materials and are packaged in transparent materials with certain strength. Lamps made of LED light sources can be used in explosive gas environments and hazardous areas, especially in the application of explosion-proof lamps. LED explosion-proof lights have good color rendering, no delay in switching, fast response, high-frequency operation, can directly emit colored visible light without filtering, and have no radiation such as ultraviolet rays. [0003] When the LED light source is working, because the light-emitting diodes are arranged neatly and have a certain distance from each other, self-dissipation during work can keep the temperature of the luminous body from exceeding the specified limit value. For densely pac...
