Background technique

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. As a solid-state semiconductor cold light source, LED has a longer lifespan than traditional light sources; in addition, LED has better controllability and light efficiency, and can save energy by as much as 50%. In terms of optics, the small light source characteristics of LED chips make it easier to achieve precise light distribution and optimal design of secondary optics. At present, most explosion-proof sight hole lamps on the market mostly use incandescent lamps and fluorescent lamps. The lighting effect is not good, it is not environmentally friendly, and it is very inconvenient to use. After use, it will affect the service life of the explosion-proof sight lamp, damage the light source, and when it encounters humid weather, moisture will easily be generated in the lamp, which will affect the use of the power supply, and there may be a short circuit phenomenon. The traditional explosion-proof sight lamp They are all in a fixed form, and the irradiation direction is also fixed, and cannot be adjusted according to needs, which is very inconvenient to use, and if there is shaking and vibration, it is easy to cause damage to the internal parts of the explosion-proof sight hole lamp and affect the explosion-proof The service life of the sight light. For this reason, we propose an explosion-proof sight hole lamp.
