Description
Technical field
The utility model relates to LED lamp technical field, relates in particular to a kind of quick heat radiating anti-explosion LED lamps.
Background technology
Explosion-proof lamp is meant the hazardous area that is used for imflammable gas and dust existence; Can prevent the inner issuable electric arc of lamp, spark and high temperature ignite imflammable gas and dust in the surrounding environment; Thereby reach the light fixture of requirement of explosion proof, different imflammable gas mixture ambient has different requirement to the explosive-proof grade and the explosion-proof form of explosion-proof lamp.Flame-proof type and INCREASEDSAFETY dual mode are arranged, and flame-proof type is applied to hazardous area, 1 district usually, the then increasing hazardous area, 2 district that is applied to of INCREASEDSAFETY.
LED explosion-proof lamp in the market can produce very high heat when in use, and long-term high hot state can make the LED explosion-proof lamp damage, and service life is not long; Certainly the LED explosion-proof lamp also has the effect of natural heat dissipation, but radiating rate is very slow, and cool effect is bad; And traditional LED explosion-proof lamp neither be very convenient when installing, and the explosion-proof lamp of flame-proof type especially is because the needs of explosion-proof criteria; The auxiliary accessories of sealing, packing ring and so on also will be set in handling blast resistance construction usually, and installing is not easily, if damage is arranged; The explosion-proof effect of reinstalling after the dismounting can be affected, and therefore traditional explosion-proof lamp is not long service life.
The utility model content
The purpose of the utility model provides a kind of long service life, quick heat radiating anti-explosion LED lamps that efficient is high.
The utility model solves the technical scheme that its technical problem adopted: a kind of quick heat radiating anti-explosion LED lamps; Comprise drive shell, lead collar, actuator chamber, light-source chamber, lead collar is fixedly connected with drive shell, and actuator chamber, light-source chamber are positioned at drive shell; Be provided with in the actuator chamber in driver, the light-source chamber and be provided with led light source; It is characterized in that: be filled with the water white transparency inert fluid in described light-source chamber and the actuator chamber, this liquid has good radiation-resistant property and high oxidation stability, hear resistance, flame resistance, ultraviolet-resistent property, chemical resistance, good damping performance and excellent electrical insulation capability, to no corrosivenesses such as metals; Drive shell comprises upper shell, lower house; On the surface of lower house, be arranged at intervals with fin, also comprise heat radiation rack, the other end of fin all is arranged on the heat radiation rack.
Described lower shell surface is circular, is arranged on the lower shell surface to the fin even angle, and described heat radiation rack constitutes a heat dissipating ring ringwise, and adjacent fin and heat radiation rack form louvre.This is arranged on the lower house of LED explosion-proof lamp and is provided with fin; And be at interval hollow out setting; Fin is fixed on again on the heat radiation rack; So just formed louvre,, then be delivered to fast on the fin of outside by metal by driving a heat part that is produced with light source because driver and light source are directly to be fixed on the Metal Substrate platform of lower house; Another part heat is delivered on the outer shell cavity wall by the mode of inert fluid with the Btu utilization convection current, is delivered in fin and the air via the chamber wall again.Drive and the difficult position of dispelling the heat of light source owing to liquid can be penetrated into, therefore driving and led light source are the radiating mode in 360 degree spaces, can not exist a certain portion temperature too high.Hollow out formula fin on the lower house through adding hot-air, can form air-flow by nature, owing to be formula on the hollow out with the heat of light fixture; Therefore increase flow velocity, accelerate radiating rate, reach the purpose of quick heat radiating through the louvre air-flow; And because this light fixture is an outdoor lamp; During extraneous air flow velocity process light fixture, because light fixture itself is a hollow out formula fin, thereby the convection current air that comes from every side all can smoothness pass through.Thereby prolonged the service life of the utility model.
Further being set to of the utility model: lower shell surface is for circular; Fin is arranged on the lower shell surface at an angle uniformly; The other end of fin is fixedly connected with the heat radiation rack of an annular, constitutes a heat dissipating ring, and adjacent fin and heat radiation rack form louvre.
This structure that entire heat dissipation is set is set to loop configuration, and fin evenly is arranged on outside the lower house, and heat radiation evenly like this; Radiating effect is best, be fixed on the annular heat radiation rack after, the back forms the taper heat dissipating ring that a side is provided with through hole; Such structure can form the thermal current that rises on heat dissipating ring; Air-flow rises around driving, and auxiliary heat dissipation further improves the speed of heat radiation.
Further being set to of the utility model: led light source is fixedly installed on the lower house; The cloche cross section is " Ω " shape, and cloche covers on the led light source, and the flange of cloche is provided with trim ring; Trim ring is fixedly connected through screw with lower house, and cloche is fixedly installed on the lower house.
This is provided with is arranged to the cloche of cross section for " Ω " shape with lampshade, and three-dimensional structure should be for having the hemispherical lampshade of flange, when installing; Earlier cloche is covered on the led light source, push down the flange of cloche then with annular pressing plate, pressing plate is fixedly installed on the lower house through screw; Such structure; All more convenient, such blast resistance construction in installation, dismounting, replacing parts, the cloche inner chamber also is an arc; Inner inert fluid has prevented that the possibility of generation spark is better, the security that has improved the utility model.
Compared with prior art, advantage of the utility model and beneficial effect: the utility model utilizes inert fluid convection current and the comprehensive derivation lamp interior of metal driving shell heat, and the possibility that produces spark reduces greatly.
