◆ Copper-free Aluminum housing with high voltage electrostatic spraying surface.
◆ Stainless steel exposed fastener with high anti-correction performance.
◆ Toughened glass cover stands 4J impact and resistant to temperature changes ,high lighting transmittance .
◆ Power driver and led source are in different cavity which assure heat of led source will not transmit to the power driver cavity.
◆ Entire explosion proof structure and spigot flameproof joint, assure reliable explosion-proof performance.
◆ Professional optical design and quadratic light distribution ,special design of reflector result in high uniformity of illumination and reasonable distribution.
◆ Special constant current power driver can assure wide voltage input and output constant current.With short-circuit and overvoltage protection, over-temperature protection etc.
◆ Adopted imported LED chips, reasonable arrangement ,soft and uniform lighting.
◆ Patent fins heat-dissipation structure increased the cooling surface area. Air convection slot design can make use of air flow to assure high quality heat-dissipation performance and longer working time .
