Description

technical field [0001] The invention belongs to the technical field of lighting lamps, and in particular relates to an explosion-proof sight hole lamp using LED as a light source. Background technique [0002] For special use environments such as petroleum, chemical industry, aerospace, military industry and explosion and flammable gas environments, electrical equipment must have certain explosion-proof performance. At present, most explosion-proof sight lamps used in special environments use incandescent lamps and fluorescent lamps. , although these two lamps can meet the requirements of explosion-proof performance, but under the same power, incandescent lamps have high power consumption and high calorific value, and the intensity of fluorescent lamps is not high enough, and these two lamps have short life, large volume, and shock resistance. Poor, light distribution accuracy is not enough, poor security and many other shortcomings. [0003] As a solid-state semiconductor ...

AI Technical Summary

Problems solved by technology

The above-mentioned public documents have the advantages of compact structure, high explosion-proof grade, and convenient installation, but there are still the following defects: one is that the heat dissipation effect is poor, and the explosion-proof requirements cannot be met, and it is easy to cause light decay and dead lights; The light distribution device is installed, so the illuminance and light distribution accuracy of LED lamp beads cannot be improved

However, there are also two major defects in the above-mentioned patented technology: poor heat dissipation and no light distribution device, so it is easy to cause light decay and dead lights, and at the same time, the light cannot be fully distributed to the required lighting space.

The achievement of this patented technology lies in: good heat dissipation effect, can achieve the purpose of cooling, but without a light distribution device, it is also impossible to improve the illuminance and light distribution accuracy, and cannot correctly control the direction of light
