Abstract

The utility model provides an LED (light emitting diode) explosion-proof light, comprising a shell, wherein a plurality of heat-radiating fins are arranged on the shell, the shell is connected with a lampshade, the bottom of the shell is connected with a fixing seat, a mounting hole is arranged in the fixing seat, a constant-current drive power supply is arranged at the bottom in the shell cavity, and an LED light-emitting module is arranged between the shell and the lampshade; the LED light-emitting module is provided with the plurality of wing-shaped heat-radiating fins; and the shell and the LED light-emitting module are connected through a thread. The LED explosion-proof light disclosed by the utility model has the advantages of intrinsic safety, high safety, simple structure, light weight, convenience for maintenance, good heat-radiation performance of lamps and long service life.

Description

The LED explosion-proof lamp
Technical field
The utility model relates to a kind of explosion-proof lamp, specifically a kind of energy-conservation, safe and reliable, LED explosion-proof lamp that heat-sinking capability is good.
Background technology
Place work and the widely-used explosion-proof lamp of scene lighting that flammable and combustible and explosive articles are arranged in chemical industry factory building, warehouse, gas station, oil well platform, oil exploitation smelting etc.The tradition explosion-proof lamp adopts incandescent lamp or mercury lamp as light source more, has the high temperature light-emitting component in the light fixture, and its caloric value is big, and the life-span is short, must take a large amount of cooling measures, causes explosion-proof lamp heaviness, complex structure, shortcoming such as easy care not.LED does not produce high temperature as cold light source, has intrinsic safety, reaches 100,000 hours service life, and the LED light fixture has energy-conserving and environment-protective, long characteristics of life-span, meets the requirement that country advocated, encouraged the new forms of energy of use energy-saving and environmental protection.
The utility model content
Weak points such as the purpose of the utility model is overcomes that traditional explosion-proof lamp caloric value is big, heaviness, complex structure, easy care, life-span be not short provide the LED explosion-proof lamp that a kind of essential safety, safe, simple in structure, in light weight, easy to maintenance, good heat dissipation, life-span grow.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of LED explosion-proof lamp comprises shell, and case body is provided with the plural pieces radiating fin; Shell is connected with lampshade, and outer casing bottom connects holder, and holder is provided with installing hole; It is characterized in that: the outer shell cavity inner bottom part is equipped with constant-current driving power supply, is provided with the LED illuminating module between shell and the lampshade.
Say that further said LED illuminating module is provided with plural finned heatsink.
Say that further said shell and LED illuminating module are through being threaded.
Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that:
(1) essential safety, safe;
(2) simple in structure, in light weight, easy to maintenance;
(3) light fixture good heat dissipation, life-span are long.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Description of drawings
Accompanying drawing 1 is the front view of a kind of embodiment of the utility model;
Accompanying drawing 2 is cross-sectional view of a kind of embodiment of the utility model;
Accompanying drawing 3 is cross-section structure decomposing schematic representations of a kind of embodiment of the utility model;
The specific embodiment
Embodiment: shown in accompanying drawing 1 to 3, a kind of LED explosion-proof lamp, shell 4 housings are provided with plural pieces radiating fin 5; Shell 4 bottoms are provided with holder 2; Holder 2 is provided with installing hole 1, and the other end that shell 4 connects holder 2 is connected with lampshade 7 through retainer ring 6, and lampshade 7 constitutes a cavity with shell 4; This cavity inner bottom part is equipped with constant-current driving power supply 3, is provided with LED illuminating module 8 between shell 4 and the lampshade 7.Shell 4 and LED illuminating module 8 are through being threaded.
LED illuminating module 8 is provided with plural finned heatsink 9, and finned heatsink 9 connects printed circuit board (PCB) 10, and printed circuit board (PCB) 10 is provided with plural led light source 11, and led light source 11 is electrically connected with constant-current driving power supply 3 through printed circuit board (PCB) 10.
In the present embodiment, led light source 11 does not produce high temperature, is the essential safe type light source, is connected with finned heatsink 9 through the printed circuit board (PCB) of installing 10, and the temperature in the time of more effectively reducing led light source 11 work prolongs 11 life-spans of led light source.The explosion-proof lamp that the utility model provides has essential safety, safe, simple in structure, in light weight, easy to maintenance, good heat dissipation, long advantage of life-span.
