หลอดไฟ LED ป้องกันการระเบิด (DDGS12/127 B)

Mine roadway lamps 12W (Round)
DGS explosion-proof LED roadway lighting is one of my company in full accordance with industry standards MT221-2005 "Coal Mine Explosion-proof lighting" in the latest explosion-proof design of roadway lighting. The product uses high-quality high-power LED light-emitting diode light source to do with a long service life, safety performance, high brightness, power consumption, operating temperature is low, the use of a wide voltage range, maintenance-free and other salient features. Can replace any previous form of roadway lighting, is a completely new, can be widely used in petroleum, chemical, coal and other flammable and explosive gases in the environment security lighting. Main technical characteristics:
1. Electricity Province
Explosion-proof LED roadway lights very low power consumption, power consumption compared to traditional light sources for 10% to 20%. DGS-18W type roadway lights, brightness equivalent to 150 ~ 200W of the old roadway lighting; DGS-12W type roadway lights, bright light equivalent to 100W of the old roadway.
2. Long life, maintenance-free, security, high performance.
High-quality LED as a light source, LED light source is greater than the life of 30, 000 hours, so that life without replacement light, tunnel lights 24 hours a day non-stop work, no maintenance, completely solved the old-fashioned light bulb to replace the problem frequently, and because LED light source operating temperature is low, so that it greatly improved safety performance.
This series of products have been carefully designed a unique, reasonable structure, using a special alloy aluminum die-casting process a shape, it has a beautiful appearance, small size, light weight, explosion-proof, shock vibration, damp heat resistance, sealing the advantages of good performance
3. Applicability.
In order to meet a large range of voltage fluctuation mine the special environmental requirements, SBD explosion-proof LED roadway lights with a unique power supply mode to operating voltage range, applicability, in AC 60V ~ 270V were able to work between the, and the brightness without any change in the coal mine is the ideal lighting lamps.
4. A unique design, beautiful shape
This series of products have been carefully designed a unique, reasonable structure,
5-year life of light intensity> 15 LUX 3 m test weight ≤ 2.2KG working environment -40 Degree~ 80 Degree Color Temperature K 5500-6000 imaging index "90 explosion-proof performance, in line with new national standards for energy-saving compared with incandescent lamps, saving about 90%, and energy-saving lamps on the market today than saving around 60%.
