Description
Technical field
The present invention relates to the explosion-proof lamp take LED as light source, particularly a kind of high conductive high strength bidirectional cooling LED blast resistance construction.
Background technology
Along with the develop rapidly of the industries such as oil, chemical industry, mining industry, the use of lighting in producing, store in a warehouse, rescuing is more and more extensive, and kind is more and more.The generation that how to prevent the blast of lighting accident in damp hazardous area has become very important problem.Because lighting inevitably produces electric spark or forms red-hot surface when working, once they meet with the explosive gas mixture of production or rescue site, will cause the generation of explosion accident, directly jeopardize national wealth and citizen's life security.Therefore,, as most popular lighting, its explosion-proof technology problem already has caused people's common concern and great attention.1813, the G. Stefansson of Britain and S.H. wore dimension and have almost invented the geordie for colliery illumination simultaneously, and it is employing special construction, can prevents from lighting the kerosene lamp of flammable explosive gas around.
Explosion-proof lamp is mainly used in the place that colliery, chemical industry, oil etc. contain flammable explosive gas, or flammable steam and mist easily and air be mixed to form the place of explosive mist, or the place of dust atmosphere, be a kind of imflammable gas and dust that can prevent that the inner issuable electric arc of lamp, spark and surface high-temp from igniting in surrounding environment, thereby reach the special Mining lamps and lanterns of requirement of explosion proof.
Explosion-proof lamp is generally classified by the light source of selecting, blast resistance construction pattern, occupation mode.By light source classification, mainly contain incandescent lamp, explosion-proof high-pressure mercury lamp, explosion-proof low-voltage fluorescent lamp, mixed light lamp etc.; Adopt the explosion-proof lamp of LED light source character on market, still to belong to very rare.
In tradition anti-explosion fluorescent lamp, substantially all contain mercury, according to scientific analysis, mercury can evaporate at normal temperatures, and the mercury of 0.5 milligram can pollute the underground water and soil of 90-180 ton, also can pollute the air of 300 cubic metres.Mercury and mercury compound can see through skin enter human body, discharges very slowly, to hepatic and renal function, the central nervous system vegetative nerve function of unifying, can cause irreversible infringement.The explosion-proof lamp of conventional light source is great to the harm of environment.
Explosion-proof lamp has flame-proof type, and (explosion-proof sign d), (explosion-proof sign e), (explosion-proof sign q), (explosion-proof sign p), (n) (DT is the close type of dirt to explosion-proof sign to Non-spark with dust explosion protection type for positive pressure type to fill sand mold for INCREASEDSAFETY, DP is dust-protection type) etc. multiple pattern, wherein first two use the most general.This product adopts INCREASEDSAFETY on type of explosion proof construc tion.INCREASEDSAFETY is a kind of the electrical equipment that can not produce spark, electric arc and dangerous temperature under normal running (operation) conditions further to be taken measures, and improves its safe coefficient, prevents that electrical equipment from producing the type of explosion proof construc tion of the possibility of dangerous temperature, electric arc and spark.It is not included in the equipment (referring to GB 3836.3 standards) that produces spark or electric arc under normal operation.
When normal operation, can not produce in the electrical equipment structure of spark, electric arc and dangerous temperature, by taking measures, reduce or control reliability, the increase insulation effect of operating temperature, assurance electrical connection and improve shell protection grade, to reduce because dirt causes the measures such as the possibility of pollution and moisture enter, reduce the possibility that occurs causing ignition fault, the security reliability under the normal operation of raising equipment and regulation fault condition.
The type equipment is mainly used in 2 hazardous areas, district, and Partial Species can be for 1st district, for example, have INCREASEDSAFETY low-pressure asynchronous motor, terminal box of appropriate protection device etc.;
In the past, in petroleum chemical enterprise, explosion hazard area lighting mainly adopt flame-proof type.Along with increased safety electrical apparatus is in the extensive use of 2 district's explosion hazard areas, INCREASEDSAFETY and compound lighting are also used more and more.The light fixture of INCREASEDSAFETY, having on the basis of certain explosion-proof performance, is compared with flame-proof type light fixture, has the advantages such as lightweight, price is low, convenient for installation and maintenance, physical life is long.
