Abstract

The utility model relates to an explosion-proof lighting fixture, especially to a LED explosion-proof lamp, which comprises a stationary cover, a translucent cover, a light source, a base plate, a lamp-socket, a driving light source, a chassis and other parts. Wherein, the light source is provided with a LED ,especiallyLED with high power as a fixed cold light source, which has the advantages of power saving, environmental protection, long durability , low driving voltage, and good explosion-proof property. The LED is arranged on the surface of the base plate which is fixed on the inner radiating flange by screw. The translucent cover is arranged above the base plate, the driving light source is fixed within the chassis by screw, and a heat dissipation hole is arranged under the lamp-socket, the lamp-socket dissipates part of the heat from the inner radiating flange and light source reacting assistant heat dissipation. The unity model is an explosion-proof lamp that the things like dust and knitting wool are not easy to strike on, which will not cause potential safety hazard and is easy to clean. The model is especially fit for places like the workplace and repertory where the inflammable and explosive goods are stored.

Description

A kind of LED explosion-proof lamp

Technical field

The utility model relates to a kind of explosion-proof light device, especially a kind of LED explosion-proof lamp.

Background technology

Existing market; most of explosion-proof lamp still adopts conventional bulb to make, and its efficient is low, and caloric value is big; the driving voltage height; easily produce spark and electric arc, improper use or voltage instability timing, even can blast; therefore need be at the full outside explosive-proof protector of making of lamp; for example adopt devices such as implosion guard and metal jube, complex structure, use cost height.And conventional bulb adopts filament light-emitting, and it is poor to have a resistance to shock, and service life is short, shortcomings such as troublesome maintenance.

Also some adopts LED as explosion-proof light source, but must consider its radiating effect.If adopt the mode of outside radiation fin, patent CN1605790A for example, its outer setting at lamp housing has the fin on a lot of outstanding centered cylinder surfaces, the heat that can effectively LED be produced sheds, but the fin shell is stained with fine particles such as dust, cotton-wool easily, be not easy to cleaning, also influence its heat sinking function, even can catch fire and cause security incident.

Summary of the invention

The utility model relates to a kind of explosion-proof lamp, especially a kind of LED explosion-proof lamp, and it comprises fixed cap, diffuser, light source, substrate, lamp socket, driving power, base.Wherein light source adopts LED, especially great power LED, and as a kind of solid cold light source, it has advantages such as energy-saving and environmental protection, long service life, driving voltage are low, and explosion-proof performance is good.Its quantity what and watt level can be regulated according to actual needs.Led light source is installed or is encapsulated in substrate surface, and substrate surface scribbles an insulation material layer, adopts the mode of serial or parallel connection to connect between the LED, links to each other with driving power by the perforate on the substrate.Substrate adopts screw to be fixed on the substrate concave surface by the screwed hole on through hole and the substrate concave surface, wherein is provided with thermal conductive silicon paper between the tangent plane place of substrate and substrate concave surface, interior fin, and the tangent plane of substrate concave surface and interior fin is in same plane.Lamp socket is an integral structure, one-shot forming, and outward appearance is pyramid type or circular platform type, and principal character is fin and interior fin outside surperficial and inside have respectively, and the center is a hollow cylinder.The heat that led light source produces passes to lamp socket by substrate, dispels the heat.Above substrate, be provided with the convex lens diffuser of birdsing of the same feather flock together, mainly be to make by implosion guard, acryl or resin material, be placed on the lens recess of lamp socket, by fixed cap it is fixed, fixed cap and lamp socket adopt screw to be connected and fixed by boss on the fixed cap and the lug on the lamp socket.Driving power is fixed in the base with screw by lug on it and the double-screw bolt on the base, and the lamp socket bottom is provided with the louvre of a circumference, a part of heat of interior fin and power supply can be exhaled, and plays the effect of auxiliary heat dissipation.Internal thread on base and the lamp socket employing base and the external screw thread mode on the base are fixed.

Described LED explosion-proof lamp, what it is characterized in that described great power LED can be in single pipe core, wafer-level package, conventional package and the surface-mounted device (SMD) is wherein a kind of.

Described LED explosion-proof lamp is characterized in that LED can be encapsulated in earlier on the other materials, is fixed on the substrate or directly to be encapsulated on the substrate again.

Described LED explosion-proof lamp is characterized in that substrate, lamp socket and base adopt one or more materials in aluminium, copper, aluminium alloy or the kirsite to make.

Described LED explosion-proof lamp is characterized in that lamp socket is an integral structure, one-shot forming.

Described LED explosion-proof lamp is characterized in that lamp socket comprises interior fin and outer fin.

The heat that LED explosion-proof lamp of the present utility model can effectively produce LED exhales, and above article such as dust or knitting wool are difficult for sticking to simultaneously, can not cause potential safety hazard, easily cleaning.Be particularly suitable for various inflammable and explosive places such as workshop, warehouse.
