Description

A kind of strong cooling LED explosion-proof lamp
Technical field
The present invention relates to a kind of with the explosion-proof lamp of great power LED as light source, particularly a kind of perfect heat-dissipating, 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 the light fixture take LED as light source generally all adopts light emitting diode chip package on heat-conducting substrate, and substrate is fixed on the heat abstractor with fin, more whole device is fixed on the appearance structure of light fixture, is combined into a light fixture.If 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 the 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 preferably radiating effect, can't very effectively control the work temperature rise of LED.LED works owing to being under the condition of high temperature for a long time, affects 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 as explosion-proof lamp, does not exist explosive-proof grade high or do not possess explosion-proof performance; For example, the LED lamp of existing employing pass-through type opening structure, 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 invention is poor for 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 again the strong cooling LED explosion-proof lamp of higher explosion-proof performance structure.
The technical solution used in the present invention 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 anti-explosion electric source capsule, 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, be provided with the metal heat-conducting fin at lamp body, the metal heat-conducting fin extends arrangement towards periphery by the LED position radially, be provided with light-source chamber at lamp body, 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, be fixedly connected with 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 by centered by the position that led light source is installed, be divergent shape and extend towards periphery arrangement, 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 the integral type 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 anti-explosion electric source capsule 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 present invention compares 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 quickly and efficiently distribute heat, 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 again higher heat radiation and explosion-proof performance simple in structure.
