Description

Flame-proof mine LED tunnel lamp
Technical field
The utility model relates to a kind of LED light fixture, is specifically related to a kind of flame-proof mine LED tunnel lamp.
Background technology
The classification of colliery illumination at present can have multiple, by scope of application classification, can be divided into surface facility illumination and mine lighting.With regard to the classification of mine lighting, can be divided into direct illumination, indirect lighting according to bright mode; Be divided into general lighting, special lighting by instructions for use; Be divided into the portable illumination of personnel, airborne illumination, tunnel illumination, chamber illumination, getting working face illumination etc. by the place to use.According to above classification led light source selecting for use under varying environment and instructions for use played great role.
For guaranteeing safety in production, improve working environment that " safety regulations in coal mine " the 473rd stipulated that clearly must there be enough illuminations in following place, down-hole: 1. shaft station and all around.2. electromechanical equipment chamber, control room, locomotive shed, magazine, waiting room, signal station, gas pumping station etc.3. the gug that uses concentrated ribbon conveyer tunnel, lifting personnel's the gug on main haulage drift, the double as pavement of locomotive and lifting material and People's Bank of China to be used alternatingly, the spacing of its illuminating lamp must not be greater than 30m.4. crossover point and the district station in main air intake lane.5. the special-purpose pavement from ground to the down-hole.6. comprehensive mechanical coal mining working face, the illuminating lamp spacing must not be greater than 15m.
Traditional tunnel lamp generally adopts incandescent lamp or high-pressure mercury lamp, and filament in red-hot working environment, not only causes gas explosion for a long time easily, and intensity is very low, and slight vibrations will be shortened the lamp holder life-span greatly, even damage.In addition, these bulb caloric values are big, the temperature height, and sintering carbon black in glass lamp shade influences light transmittance easily, also is difficult to remove.Common illuminating lamp reduces with voltage, and illumination obviously descends, and voltage raises, and luminous efficiency significantly improves again, but obviously shorten service life.LED is as the novel light-emitting device, has characteristics such as light efficiency height, life-span are long, low in energy consumption, shock-resistant, non-maintaining, anti-vibration.Therefore be the deficiency that tunnel lamp that the illuminator exploitation forms has solved conventional lamp with LED: 1. energy-saving safe, environmental protection; 2. penetration power is strong, illumination is big; 3. good, the life-span length, non-maintaining of shock resistance reduces and changes lamp number of times (3 years non-maintaining), alleviates labor strength greatly; 4. influence by voltage is little, and illumination is stable; 5. have the kinds of protect circuit, can solve outage, protection, problem such as emergent.
Therefore solve the lighting safety problem of mine, for lighting apparatus strict requirement is being arranged aspect the mine illumination, it must possess the function of aspects such as fire prevention, explosion-proof, protecting against shock and waterproof, for all kinds of light fixtures that use in the mine, all must take safety prevention measure preferably, especially at colliery underworkings and the chamber of explosive mixture gases such as methane, coal dust.
Also just because of above-mentioned reason, so mine explosion-suppression LED tunnel lamp is a kind of indispensable lighting in the safety in production, at present, this light fixture that sell in market has generally adopted the new LED light source, much consider the convenience of installation, economy, the led light sources that adopt more, led driver is put together, be contained in the lamp casing jointly, because the portion of energy of led light source is converted into heat energy, the temperature of light fixture is promoted rapidly, at high temperature working for a long time is easy to make it to damage, and facts have proved in the light fixture that the damage of led light source and power supply is that electrical part at high temperature wears out and causes substantially, thereby has reduced the life-span of light fixture.
