Description
Technical field
The utility model relates to a kind of LED explosion-proof lamp.
Background technology
Along with the develop rapidly of industries such as oil, chemical industry, lighting produce, use in the storage, rescue more and more widely, kind is more and more.The generation that how to prevent the blast of lighting accident in the damp hazardous area has become crucial problem.Because lighting can produce electric spark inevitably or form red-hot surface when work, they are in case 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 has just caused people's common concern and great attention.
The explosion-proof lamp of market is based on ordinary lamp and lantern at present.Such-and-such problem is all arranged in these explosion-proof lamps.Outstanding problem is that radiating effect is bad, causes the lamp interior junction temperature too high, dissolves cushion rubber, and is explosion caused, loses explosion prevention function etc.
Summary of the invention
The purpose of this utility model is to provide a kind of LED explosion-proof lamp, and it is simple and reasonable, no junction temperature, no-spark, and good heat dissipation effect, easy to use.
The purpose of this utility model is achieved in that a kind of LED explosion-proof lamp, the power pack of LED driving power is housed in comprising, the bottom of power pack is connecting a lamp body heat dissipation plate by bolt seal, led light source and lens lampshade are being set respectively in the center lamp socket of heat dissipation plate from top to bottom, between the annular outer peripheral edges end face of lens lampshade and the lamp socket annular shoulder block red copper flame proof liner is being set, pressure pad and pressure ring are being set respectively in the lamp socket under the annular outer peripheral edges bottom surface from top to bottom; The uniform heat dissipation channel that is centrosymmetric and arranges that is being provided with of vertical spacing on the lamp body heat dissipation plate disk body around the lens lampshade.
The utility model is simple and reasonable, no junction temperature, and integrated LED high-power lamp pearl, heat radiation requires strict more.We utilize this characteristic of LED integrated high-power lamp pearl, the design metallic aluminium die casting one-shot forming of perfect heat-dissipating, the uniform heat dissipation channel that is centrosymmetric and arranges that is being provided with of vertical spacing on the lamp body heat dissipation plate disk body around the lens lampshade, empty calory alluvial phenomenon, radiating effect is very outstanding.Between the annular outer peripheral edges end face of lens lampshade and the lamp socket annular shoulder block red copper flame proof liner is being set, pressure pad and pressure ring are being set respectively in the lamp socket under the annular outer peripheral edges bottom surface from top to bottom; Both guaranteed the heat radiation requirement of light fixture, solved light fixture working junction temperature problem again, and fundamentally solved because of red-hot temperature and explosive gas mixture meet and produced the danger of blast.No-spark, the LED light emitting diode must be through strict encapsulation, the ability operate as normal, domestic encapsulation technology has reached international standard at present.The exposed electrification phenomenon of exhausted nothing.For LED provides the power unit of transformation work, we adopt moulding encapsulating technology, and are anchored on housing with screw, have really stopped to produce pyrophoric behavio(u)r in the light fixture course of work, and are easy to use.

The specific embodiment
A kind of LED explosion-proof lamp as shown in Figure 1 and Figure 2, is equipped with the power pack 18 of LED driving power 23 in comprising, foamed silastic O RunddichtringO 26 is being set between power pack 18 and the power supply lid 2.The bottom of power pack is connecting a lamp body heat dissipation plate by bolt seal, between the lower, outer perimeter edge annular shoulder block of power pack and the upper, annular flange of heat dissipation plate foamed silastic O RunddichtringO 27 is being set.Led light source 12 and lens lampshade 11 are being set respectively in the center lamp socket of heat dissipation plate from top to bottom, and led light source 12 links to each other by the binding post 3 in lead and the power pack 18.Between the annular outer peripheral edges end face of lens lampshade 11 and the lamp socket annular shoulder block red copper flame proof liner 14 is being set, in the lamp socket under the annular outer peripheral edges bottom surface of lens lampshade 11 pressure pad 25 and pressure ring 10 is being set respectively from top to bottom, so that fixed lens lampshade 11.The uniform heat dissipation channel 81 that is centrosymmetric and arranges that is being provided with of vertical spacing on the lamp body heat dissipation plate disk body around the lens lampshade 11, the heat that led light source 12 produces are upwards discharged by heat dissipation channel 81 and flow away.
Said heat dissipation channel 81 is being provided with radiator shutter 82 between the adjacent heat dissipation channel 81 between lamp socket and lamp body heat dissipation plate annular periphery wall 8, radiator shutter 82 is connecting the annular periphery wall 8 of lamp socket and lamp body heat dissipation plate.
The bottom surface, lower end of each radiator shutter 82 links to each other and is horn-like, and the horn-like bottom surface of each radiator shutter 82 is to be the wavy continuous curve surface 13 that the horizontal circle annular is arranged, can cross the expansion area of dissipation like this, can prevent the heat alluvial again.
Between the radiator shutter 82 of heat dissipation plate, the both sides of lamp socket vertically are being provided with two Connection Blocks 30 respectively, are connecting a font suspension holdfast 1 by bolt on the Connection Block 30.
The utility model is simple and reasonable, and during use, a large amount of heat energy that led light source 12 produces can access sufficient release, good heat dissipation effect by heat dissipation plate.This explosion-proof lamp is not afraid of collision, and LED explosion-proof lamp lens adopt excellent safety glass to make, and the fastening silicon rubber secondary of smearing simultaneously of screw is fixed, and has fully guaranteed the security of light source.Power pack has been designed to square, equally uses the metallic aluminium one-step die casting, is that profile or intensity all are than general explosion-proof lamp requirement height.
