Mine machine lights DGY9 / 36L

LED constant current drive circuit drives are ideal, the disadvantage is the higher price. Constant load short circuit, although afraid, but non-load completely open. Current constant current drive circuit output is constant, and the output DC voltage but with the load resistance of different sizes varied within a certain range. To limit the number of LED use, because it has to withstand the maximum current and voltage values. Zhejiang Three music, R & D and sales, factory direct sales of various types of explosion-proof lighting fittings and the entire light . Welcome to your call to discuss. DGY9 / 36L flameproof lighting (hereinafter referred to as lamp) is widely used in various mining electric locomotives and various types of mining locomotive lighting. Environmental conditions [a] altitude does not exceed 1200m;.. B ambient air temperature is -20 ℃ ~ + 40 ℃; c ambient air humidity; The monthly average humidity less than 95% (the average temperature of not more than 25 ℃,). . d with respect to the longitudinal direction of the locomotive, the lateral and vertical vibration amplitude shall meet the following conditions; (f- vibration frequency, A- amplitude); A≤25 / f (f is 2-10Hz) A≤250 / f2 ( f is 10-50Hz) e relative to the longitudinal acceleration of the locomotive is not greater than 30m / s2;. g explosive mixture of methane and coal dust containing applicable; f in the air enough to corrode metal and damage the insulation of gas and conductive dust. environment. DGY9 / 36L / 127L flameproof machine lights [Basic parameters] Model DGY9 / 24L DGY9 / 48L DGY9 / 127L rated voltage DC24V DC48V DC127V LED light source rated power forward voltage of 10.5V 9W; according to distance 40M; illuminance ≥2LX ; quality 8KG DGY9 / 36L, 9W mining locomotive lighting suitable environmental conditions: 1. Ambient Pressure 86Kpa-106Kpa; 2. Ambient temperature -20 degrees - +40 degrees; 3. The air relative humidity not more than 75% (temperature + 25% degrees Celsius); 4. voltage fluctuations within the range of 60% -130% of rated lamp can work; 5. Protection class: IP65. DGY9 / 36L mining machine lights Features: 1) Long life: the life of ordinary light an average of 7000 hours under the conditions of voltage fluctuation shorter life expectancy; LED lamps during use without replacement maintenance, saving maintenance costs. 2) a significant saving: LED lighting is a low voltage, low current products, only a fraction of the power of ordinary lamps, saving 70 to 90%, greatly reducing the cost of cable and auxiliary materials supporting the installation time?. 3) Green light: flux instability in ordinary light emitted from the light source, resulting in flash, when the flicker over a certain range, it will produce visual fatigue, long-term vision fatigue can affect the human visual system. LED lamp current stability, will not produce any flicker, the human body without harm. LED lamp illumination brown pattern design more humane, will not produce light pollution. LED lamps have mosquitoes, work at night than the light of a variety of environments, no interference by mosquitoes, head of long-term state in clear and bright, is a green light.
