Description
Technical field
The utility model relates to a kind of with the explosion-proof lamp of great power LED as light source, particularly a kind of perfect heat-dissipating, the strong cooling LED explosion-proof lamp that explosion-proof performance is strong.
Background technology
The structure of traditional explosion-proof lamp often all is with the structure of robust sealed light source and electrical equipment and outside to be isolated, and realizes explosion-proof purpose.And be that the light fixture of light source generally all adopts light-emitting diode chip for backlight unit is encapsulated on the heat-conducting substrate with LED, substrate is fixed on the heat abstractor that has fin, more whole device is fixed on the appearance structure of light fixture, is combined into a light fixture.If it is inevitable relatively poor according to the LED explosion-proof lamp radiating effect that the structure of traditional explosion-proof lamp is made, this enclosed structure can not form heat-conducting mediums such as air, water in its surperficial good fluidity, and the heat exchange effect between the surrounding environment is not good, thereby can not reach better radiating effect, can't control the work temperature rise of LED very effectively.LED works owing to being under the condition of high temperature for a long time, influences its luminous efficiency, and light decay is serious, and the lost of life is so that can not normal luminous work.Though the comparatively desirable LED light fixture of radiator structure is also arranged in the prior art, when using, does not exist explosive-proof grade high or do not possess explosion-proof performance as explosion-proof lamp; For example, the LED lamp of the opening structure of existing employing pass-through type, it has very strong heat sinking function, but its structure explosion-proof performance is poor, does not meet the requirement of explosion-proof electrification.
Summary of the invention
Task of the present utility model is poor at the existing explosion-proof performance of existing LED light fixture, do not meet the explosion-proof electrification requirement weak point, provide a kind of ventilation and heat performance good, and have the strong cooling LED explosion-proof lamp of higher explosion-proof performance structure again.
The technical solution adopted in the utility model is finished in the following way: a kind of strong cooling LED explosion-proof lamp, it comprises the lens gland, convex lens, led light source, lamp body, the explosion-proof electrical source box, driving power, explosion-proof electrical source lid and explosion-proof wiring lid, led light source adopts high-power LED light source, lamp body adopts radiator structure, on lamp body, be provided with the metal heat-conducting fin, the metal heat-conducting fin extends arrangement towards periphery by the LED position radially, on lamp body, be provided with light-source chamber, power source cavity and wire connection cavity, led light source places light-source chamber, driving power places power source cavity, wiring construction places wire connection cavity, wherein, fixedly connected for being close between led light source and the lamp body.
In above-mentioned a kind of strong cooling LED explosion-proof lamp, the metal heat-conducting fin on the lamp body is to be the center by the position that led light source is installed, be divergent shape and extend arrangement towards periphery, and be penetrating between the metal heat-conducting fin on the lamp body.
In above-mentioned a kind of strong cooling LED explosion-proof lamp, lamp body is an integral structure, and lamp body adopts the material with good heat conductive performance and heat-radiating properties to make.
In above-mentioned a kind of strong cooling LED explosion-proof lamp, lamp body adopts aluminium or hydronalium casting to form.
In above-mentioned a kind of strong cooling LED explosion-proof lamp, adopt the socket joint type structure to be fixed together between explosion-proof electrical source box and the explosion-proof electrical source lid.
In above-mentioned a kind of strong cooling LED explosion-proof lamp, adopt the socket joint type structure to be fixed together between explosion-proof electrical source lid and the explosion-proof wiring lid.
The utility model is compared with existing LED light fixture, has following characteristics: with the radiator structure of LED light fixture directly as the appearance structure of light fixture; Radiator structure adopts pass-through type, fin arrangement to be divergent shape, is convenient to distribute heat quickly and efficiently, thereby guarantees the normal working temperature of LED, improves and keep luminous efficiency and the minimizing light decay of LED, life-saving; Simultaneously, led light source is placed the different individual cavity that meets the explosion-proof electrification specification requirement with electric components such as driving powers, become the LED explosion-proof lamp that has higher heat radiation and explosion-proof performance again simple in structure.
