Safety Requirements Of Paint Booth Lighting

- May 07, 2020-

In light with National Fire Protection Association (NFPA), a paint booth is a class I division one area, which means an area where ignitable or flammable chemical in aqueous or gaseous states exist in the area. Since all electrical appliances in the spray booth, including the lights and other machines, must be protected from ignition, we have the special consideration of the LED lights. To improve the safety, we adopt low power, high luminous efficiency LED chips to make the total power drawn from the lights as low as possible.

Heat plays a vital role in the drying process after finishing the spray. The interior temperature of the drying room should be at least 55°C for the better finishing. The duration and temperature of coating process needs varies with different paints you use. But 55°C is a bottom line. A widely accepted rule in spraying industry is that for every 15 degrees above 70 degrees, the speed of the drying process will be doubled. On the contrary, for every 15 degrees below 70 degrees, the process will take 2 time longer. And hence, we understand that the ambient temperature inside the paint booth and drying room is quite high.

Our LED lights resists high temperature up to 90°C inside the paint booth because of our exclusive heat dissipation system, quality chips and heat-resistant Meanwell power supply. We adopt 7 watt & 5 watt single LED chips. Their luminous efficiency reaches 160 lm/w and 180 lm/w respectively.
