Explosion-proof rating of explosion-proof LED lights
Most of the explosion-proof lamps and lanterns are protected against electric shock as Class I lamps and Class III lamps. For example: all-plastic explosion-proof lamps, explosion-proof flashlights.
1. Classified according to the protection level of the shell: in order to prevent dust, solid foreign objects and water from entering the lamp cavity, touching or accumulating on live parts to cause flashover, short circuit or damage to electrical insulation and other dangers, there are a variety of shell protection methods. Protects the role of electrical insulation. The enclosure protection level is characterized by the characteristic letter "IP" followed by two numbers. The numbers indicate the ability to protect against people, solid foreign objects or dust. Divided into 0-6 grades. Explosion-proof lamps are sealed lamps, and their dust-proof ability is at least grade 4. The numbers indicate the protection ability against water, which is divided into grades 0-8.
2. Classification according to the supporting surface material of the lamp design: Indoor explosion-proof lamps may be installed on many surfaces belonging to ordinary flammable materials, such as wooden walls and ceilings. They do not allow the temperature of the installation surface of explosion-proof lamps to exceed the value. According to whether explosion-proof lamps can be directly installed on the surface of ordinary flammable materials, they can be divided into two categories.
Explosion-proof type with high explosion-proof grade, can work reliably in flammable and explosive dangerous places.
1. High-intensity gas discharge lamps are used as light sources, with high luminous efficiency and an average service life of more than 10,000 hours.
2. The use of prismatic tempered glass, without glare, can effectively avoid discomfort and fatigue of operation and construction personnel.
3. Use shading plate and carry out light design, improve the utilization rate of light efficiency, and have a good energy saving effect.
4. The integrated full-tight structure design and new surface treatment skills are selected. The appearance is beautiful, the equipment is simple, it is resistant to rain and water spray, and the shell of the lamp is not corroded or rusted. It can be used in harsh environments such as high temperature, humidity and various corrosive conditions. long-term use.
5. The shell is made of high-strength aluminum alloy material, which has the ability to resist collision and impact.
6. A variety of equipment methods such as boom type and wall-mounted type are suitable for the lighting needs of different job sites.
