Summary of the invention
The object of the present invention is to provide a kind of protected against explosion mine laneway directional lighting lamp, this illuminating lamp overcomes the deficiencies in the prior art, and structure is simple, not only good seal performance, and can be effectively explosion-proof, safe and reliable, non-maintaining, extends service life.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is: a kind of protected against explosion mine laneway directional lighting lamp, comprise upper cover, safety guard, glass lamp shade, reflector, the lamp body of band radiator, the power driving circuit plate being provided with power driving circuit and LED light source, bottom, clamp nut; Be covered on described lamp body front end, described bottom is located at the rear end of lamp body, reflector is fixed on the periphery of LED light source, described glass lamp shade is by the front end of glue at lamp body, safety guard is fixedly mounted on upper cover and lamp body, bottom and lamp body form explosion-proof wire connection cavity, power cable is tightly connected by clamp nut and caulking gum and pad and lamp body, power driving circuit plate is electrically connected with power cable and LED light source respectively, LED light source is arranged on lamp body, it is characterized in that: the explosion suppresion surface between described lamp body and bottom is provided with unidirectional moisture seal ring.
Between described lamp body and bottom, the length of longitudinal L1 of explosion suppresion surface is 16.5mm; Gap width L2 between lamp body and bottom≤0.3mm.
Explosion suppresion surface between described lamp body and bottom is coated with antirust paint.
Are-tight paint is coated with in the cavity formed between described bottom and lamp body.
The fitting surface even application be arranged between LED light source on lamp body and lamp body has one deck thermal grease conduction.
The invention has the beneficial effects as follows: because the explosion suppresion surface between the lamp body of this protected against explosion mine laneway directional lighting lamp and bottom is provided with unidirectional moisture seal ring, good sealing effect, thus without condensation in lamp body cloche, light fixture cavity and outside air do not have gas exchanges, stop extraneous gas and enter lamp body inside, overcome the defect that explosion separation structure is intrinsic, structure is simple, can be effectively explosion-proof, safe and reliable, non-maintaining, effectively improve the serviceability of product, extend service life.
