Description

The great power LED explosion-proof lighting lamp

Technical field

The utility model relates to explosion-proof bright lamp tool technology, particularly a kind of great power LED explosion-proof lighting lamp of the employing great power LED light emitting diode in hazardous gas, dust, colliery, oil, the special use of military place.

Technical background

Traditional thermal light source type light fixture is generally adopted in present hazardous area and military project illumination, and as high-pressure mercury lamp, metal halide lamp, fluorescent lamp, even some local usefulness is incandescent lamp.The general luminous efficiency of these light fixtures is low, has only 11%-25%, the waste electric energy; And producing a large amount of heat, the life-span is short, maintenance cost is high, and it is bad to develop the color, and dazzle is arranged.And contain mercury and fluorescent material in the fluorescent lamp, environment there is pollution.Particularly work out of doors, natural environment and weather conditions are more abominable, and the waste of light fixture is very big, particularly bulb, ballast and trigger.

At present, the application of low-power LED light emitting diode both at home and abroad is a lot of, but all is to be used in the demonstration of display screen mainly, and flashlight also has application, does not also occur the white light great power LED is applied on the explosion-proof illuminating lamp in high-risk place.Build in current call under the situation of economizing type harmonious society, LED need be applied on high-risk gas, dust, colliery, oil, the military place illuminating lamp especially.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, and a kind of great power LED explosion-proof light floodlight is provided, and to reduce electric energy loss, reduces maintenance cost, reduces environmental pollution, improves illuminating effect.

For achieving the above object, the utility model provides a kind of great power LED explosion-proof lighting lamp, comprise substrate lamp housing and thermal column, also comprise LED light emitting diode and constant-current driven module, power supply connects constant-current driven module, the drive output of constant current drive block is in series with a plurality of LED, each LED zener diode all in parallel.

Aforesaid great power LED explosion-proof lighting lamp, described substrate lamp housing can adopt the channel shaped aluminium base.Each LED is added with the light-focusing type lens.Comprise by AC power also connecing Switching Power Supply that by the Switching Power Supply constant-current driven module that goes between, drive the great power LED group of series connection by constant-current driven module, LED is installed on the explosion-proof thermal column, is dispelled the heat by thermal column.

The utility model compared with prior art has tangible advantage and beneficial effect.By above technical scheme as can be known, the great power LED explosion-proof illuminating lamp of the utility model technology has following major advantage:

1. adopt the cold light source great power LED, the luminous efficiency height, conservation of power, the incandescent lamp of equal light efficiency can be saved 80% electric energy loss.Long service life and highly stable, light decay needs more than 100,000 hours to 50% of initial value.Because great power LED is a DC driven, so luminous no stroboscopic develops the color, free from glare makes human eye perceives comfortable, and is not tired.Can arrive 70 degree operate as normal above freezing at 40 degrees below zero, and LED does not produce any environmental pollution.Maintenance cost is low.

2. adopt constant current drive integrated circult piece, components and parts are few, and it is little to generate heat, not fragile, and each LED can also keep obtaining constant current under the situation of voltage pulsation, and is highly stable.

3. each great power LED Zener diode in parallel can puncture conducting when single LEDs damages, and does not influence the work of whole LED group, prolongs light fixture service time.

4. adopted the channel shaped aluminium base, increased the LED area of dissipation, increased the service life.

Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is elaborated.

5.LED be installed on the thermal column good heat dissipation effect.
