What are the requirements to qualify for explosion proof lamp? The following is the introduction of Ouhui Lighting.

1. electrical components electrical components should meet the relevant national standards, can withstand the working temperature of the lamp cavity for a long time, to provide electrical parameters to match the light source, and can meet the requirements of various explosion proof explosion proof lamp.

2. junction box wiring cavity size must be designed to meet the specific explosion-proof performance requirements, and should also facilitate wiring, leaving space for wire bending radius, to ensure that the wiring is correct after the electrical gap and creepage distance in line with the relevant standards, should be painted on the inside of the metal shell wiring cavity and anti-electricity coating, so as not to generate sparks during normal operation.

3. Connectors and terminals

A. Connectors and bushing terminals should have sufficient mechanical strength to prevent damage during the wiring process. Wiring should be solid and reliable, anti-loose, vibration can not vibrate the conductor and insulator thermal expansion and contraction loosening.

B. The design of the power connector of the explosion proof lamp should make stranded wire wiring, if the cable head is removed from the terminal, it will not touch the surrounding metal parts.

C. terminals should take measures to prevent loosening to prevent the root of the terminal wire breakage. It is not allowed to press the connection wire directly with the screw head, which can easily damage the terminal.

Research data shows that because LED is a cold light source, semiconductor lighting itself has no pollution to the environment. Compared with incandescent and fluorescent lamps, LED power saving efficiency can reach more than 90%. In the same brightness, power consumption is only 1/10 of ordinary incandescent lamps and 1/2 of fluorescent tubes. if we use LED to replace 50% of the existing traditional lighting, the energy-saving benefits are considerable.

LED of explosion proof lamp is a healthy light source that can protect eyesight and is harmless to the environment. It not only provides a comfortable lighting space, but also meets people's physical health needs. Good dimming performance, no visual error when the color temperature changes; cold light source, low heat, safe to touch; not applicable to incandescent and fluorescent lamps.

Because individual LEDs currently have low power and low brightness, they are not suitable for individual use, and LED explosion-proof lights are assembled together to design practical LED explosion-proof lights have broad application prospects.

The luminaire designer can determine the number of explosion proof led lights and the power of the luminaire optical system according to the lighting object and luminous flux requirements. It is also possible to design several LED lighting tubes as point light sources, ring or surface light sources. Luminaires are designed according to the combination of "secondary light sources.
