Description

The LED explosion-proof lamp
Technical field
The utility model relates to a kind of LED lamp, relates in particular to a kind of LED explosion-proof lamp.
Background technology
Explosion-proof lamp is meant and is used for the hazardous area that imflammable gas and dust exist, and can prevent the inner issuable electric arc of lamp, spark and high temperature ignite imflammable gas and dust in the surrounding environment, thereby reaches the light fixture of requirement of explosion proof.Along with the develop rapidly of industries such as oil, chemical industry, mining industry, explosion-proof lamp is used also more and more widely.Explosion-proof lamp the inside dress is incandescent lamp mostly at present, and all than higher, power consumption is bigger, not energy-conserving and environment-protective for the incandescent lamp energy consumption.In the used lamp of illumination now, energy-conserving and environment-protective just belong to the LED lamp, the LED lamp is able to large-scale popularization with advantages such as the high and low power consumption of its brightness, life-span are long.But the LED lamp in use, and it is exactly the problem how heat that sends discharges that a unfavorable factor is arranged, untimely because heat is discharged; Temperature is too high; Can influence optical efficiency and service life, be in the space of a sealing for explosion-proof lamp particularly, and heat radiation is a difficult problem especially; Also do not have good way to solve till now, LED is not used for explosion-proof lamp yet.
The utility model content
The utility model technical problem to be solved is to provide a kind of LED explosion-proof lamp of good heat dissipation effect.
The technical scheme of the utility model is following: a kind of LED explosion-proof lamp; Comprise lamp holder (2), electrical equipment cover (3), lampshade (4), heat-radiating substrate (5), led board (6) and automatically controlled plate (8); Wherein said electrical equipment cover (3) upper end connects lamp holder (2); This electrical equipment cover (3) lower end connects lampshade (4), and its key is: said lampshade (4) lower openings, and automatically controlled plate (8) is equipped with on said electrical equipment cover (3) top; This electrical equipment cover (3) lower end is provided with heat-radiating substrate (5) and led board (6), is distributed with venthole (3a) on the outer circumference surface of said electrical equipment cover (3) top; This heat-radiating substrate (5) upper surface vertically is connected with fin (7), and said fin (7) upper end is provided with fan (9), this fan (9) updraft, and said automatically controlled plate (8) is positioned at fan (9) top.The LED explosion-proof lamp in use, the heat that led board (6) produces imports in fin (7) and heat-radiating substrate (5) the top air through heat-radiating substrate (5), the outer air themperature of electrical equipment cover (3) is relatively low; Get in the electrical equipment cover (3) through lampshade (4) lower ending opening, fan (9) updraft this moment is upwards sent the hot-air below the fan (9); Get rid of through venthole (3a); Upper and lower forms convection current, because hot-air makes progress the reason that cold air is downward; Add the powerful exhausting of fan (7); A large amount of hot-airs is rejected in the explosion-proof lamp shell, spreads out of heat through shell (1), the cold air that temperature reduces sinks to the explosion-proof lamp lower housing portion again from the lower air of lampshade (4) lower ending opening inlet temperature.Whole LED explosion-proof lamp radiating effect is very good.
Above-mentioned electrical equipment cover (3) links to each other with lampshade (4) butt joint buckle; Said heat-radiating substrate (5) edge is positioned at the access section of electrical equipment cover (3) and lampshade (4); Said lampshade (4) access section inwall is provided with ring-shaped step; This heat-radiating substrate (5) edge is placed on the ring-shaped step, and inwall extension in said electrical equipment cover (3) access section props up heat-radiating substrate (5).During the clamping assembling, simultaneously that heat-radiating substrate (5) is fixing, the improvement that these are a series of all is the convenience in order to assemble, and raises the efficiency to reduce cost.
Above-mentioned leg (10) upper end is structure as a whole with electrical equipment cover (3), and this leg (10) lower end is trapped among automatically controlled plate (8) periphery, and the corresponding automatically controlled plate in said leg (10) lower end (8) has mounting groove, and said automatically controlled plate (8) inserts in leg (10) mounting groove fixing.Supporting leg and electrical equipment cover (3) one can one-body moldedly be made, and supporting leg has certain elasticity; The supporting leg lower end is promoted outwardly; Automatically controlled plate (8) is put into the mounting groove of leg (10) lower end, and a plurality of supporting legs are easy to and are fast that automatically controlled plate (8) is fixing, have further simplified assembly process.
Above-mentioned fin (7) upper end is positioned at the windproof back flow plate (11) that annular is stamped in fan (9) periphery.Under the same terms, can increase air quantity, improve heat dissipation capability through fin (7).
Above-mentioned venthole (3a) is evenly distributed on electrical equipment cover (3) outer circumference surface, and is the bar hole that vertically distributes.Can reduce the resistance that extraneous air gets into, radiating effect can be better.
Beneficial effect: the utility model is reasonable in design, and LED has been used for explosion-proof lamp, has solved heat dissipation problem; Utilize simple structure, improve radiating effect greatly, also simplify the structure greatly on this basis and processing, assembly process; Feasible assembling is simpler; Efficient is better, can't increase cost, obtains promotion and application easily.
