LED explosion-proof lamps are explosion-proof lamps, and the principle is the same as explosion-proof lamps
The explosion-proof joint surface of the explosion-proof lamp should be properly maintained and not damaged; other paints should not be painted; there should be no rust layer on the explosion-proof surface. The sealing ring used for dustproof and waterproof must be kept intact, which is very important for the increased safety lamps. If the sealing ring is severely damaged, replace it with a sealing ring of the same standard and material, and replace the entire lamp if necessary. When overhauling, pay attention to whether the lampshade is in good condition. If it is split, replace it immediately.
Two basic classification standards for explosion-proof lamps
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. Classified according to the degree of protection of the enclosure: in order to prevent dust, solid foreign objects and water from entering the lamp cavity, touching or accumulating on live parts, resulting in the risk of flashover, short circuit or damage to electrical insulation, there are a variety of enclosure protection methods to maintain electrical The role of insulation. The enclosure protection level is characterized by the characteristic letter "IP" followed by two numbers. The numbers indicate the protection against people, solid foreign objects or dust. Divided into 0-6 grades. Explosion-proof lamps are a kind of sealed lamps, and their dust-proof ability is at least grade 4. The figures indicate the protection ability against water, which is divided into grades 0-8.
Precautions for installation of explosion-proof LED lights Before installation, check whether the actual operating conditions are consistent with the parameters on the lamp. Before installation, please carry out the power-on and lighting test according to the parameters of the lamp nameplate to ensure that the lamp has no quality problems before installation. Before installation, confirm the installation position and installation method of the lamp according to the installation method provided by this product in combination with the on-site use environment and lighting requirements to ensure that the installation is firm and reliable. Connect the prepared cable to the input cable of the luminaire according to the live wire (brown), neutral wire (blue), and ground wire (yellow-green) to ensure that the connection is firm, and insulation and waterproof measures should be taken at the connection.
LED explosion-proof lamps are explosion-proof lamps, and the principle is the same as that of explosion-proof lamps, except that the light source is LED light source. One of the very important explosion-proof principles of LED explosion-proof lamps is that the temperature of the surface of the shell, the surface of parts or electronic components that the dust contacts, and the temperature of the electrical contact surface are lower than its combustion temperature or ignition temperature.
Since LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low power consumption, low voltage, working voltage, and long service life. Therefore, high-power white LEDs are explosion-proof lamps, especially portable explosion-proof lamps. Aspiring electric light source.
