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.
