Description
Technical field
The utility model relates to a kind of illuminator lamp, is specifically related to a kind of optically focused Down lamp.
Background technology
At present, the optically focused Down lamp that occurs on the market in the course of the work heat radiation and the flameproof effect during breaking out of fire be still waiting further raising.When breaking out of fire, flare is up scurried rapidly, and the structure that plays anti-fire action is destroyed and break away from the cylindrical shell of optically focused Down lamp under the high velocity air that produces because of burning, and unstable working condition loses the fireproof function.The optically focused Down lamp when lamp holder is installed, operation inconvenience, and easily with the electric wire flexion in cylindrical shell, electric wire bends for a long time under hot environment, the life-span shortens.
The utility model content
The purpose of this utility model is for a kind of handling safety, easy being provided, can improving the optically focused Down lamp of job stability, service life and fire protecting performance.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of optically focused Down lamp, comprise cylindrical shell, be located at lamp holder in the cylindrical shell and bulb, the electric wire of connection lamp holder, described cylinder top is provided with and the integrated top cover of cylindrical shell, described top cover is provided with louvre, top cover one side is provided with circular fireproof material layer, the thermal insulation layer with the cylindrical shell coupling successively, and described top cover is fixed as one fireproof material layer, thermal insulation layer by rivet.
More excellent, the louvre on the described top cover, rivet are evenly, are symmetrically distributed.
And described electric wire is provided with cableties, and described cableties are fixed on the electric wire by the line hole which is provided with.
The utility model is provided with the top cover of band louvre in cylindrical shell upper end, top cover is by rivet fixedly fireproof material layer, thermal insulation layer successively, and when this structure can prevent effectively that fire from taking place, thereby flare is up run helter-skelter and made fire spreading.Louvre on the top cover can dispel the heat when operate as normal, and when breaking out of fire, the fireproof material layer of top cover one side is burned, the fire proofing material of fireproof material layer the inside expands because of being heated, because stopping of thermal insulation layer, the fire proofing material that expands is extruded to the slit between louvre and fireproof material layer and the cylinder inboard wall, and louvre and slit be because of the expansion blocking of fire proofing material, thereby prevents spreading of the intensity of a fire.Louvre and rivet are arranged on the top cover ringwise equably, make that the expansion of fire proofing material is more even, and the heat-resistant time after the expansion is longer.
And top cover that cylinder top is provided with and cylindrical shell are one-body molded, can prevent that fireproof material layer breaks away from the cylindrical shell of optically focused Down lamp under the effect of the high velocity air that produces because of burning, thereby make fireproof material layer be fixed in the cylindrical shell all the time, flare can not spread from cylindrical shell in the short time outward, reaches the effect that prolongs the fire prevention time.
The utility model has been placed cableties on electric wire, can be so that electric wire be vertical with the cylindrical shell bottom surface, and the lamp holder of outwarding winding, it is sagging that lamp holder and bulb get final product nature, and the lamp holder of packing into then only needs vertically up to promote lamp holder to get final product, installing/dismounting is convenient, quick.Because this kind setting need not long electric wire, electric wire can not shorten the life-span because of bending for a long time in the cylindrical shell of high temperature, has therefore improved the whole service life of optically focused Down lamp.

Among the figure: 1, cylindrical shell; 11, top cover; 12, fireproof material layer; 13, thermal insulation layer; 14, louvre; 15, rivet; 2, lamp holder; 3, electric wire; 4, cableties; 41, line hole; 5, bulb.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figures 1 to 3, a kind of optically focused Down lamp comprises whole cylindrical cylindrical shell 1, is placed in lamp holder 2 and bulb 5 in the cylindrical shell 1, connects the electric wire 3 of lamp holder 2, and electric wire 3 is provided with cableties 4, and cableties 4 are fixed on the electric wire 3 by the line hole 41 that cableties 4 are provided with.The top of cylindrical shell 1 is provided with the top cover 11 of band louvre 14, and a side of top cover 11 is fixed with circular fireproof material layer 12, the thermal insulation layer 13 that mates with cylindrical shell 1 successively by rivet 15, and louvre 14 and rivet 15 are the ring adequate relief and are arranged on the top cover 11.Top cover 11 and cylindrical shell 1 one-body molded design on cylindrical shell 1 top can prevent that the high velocity air that fireproof material layer 12 is produced because of burning is pushed into cylindrical shell 1 outside, cause flare up to be run helter-skelter, and lose fire-proof function.
The utility model is provided with the top cover 11 of band louvre 14 in cylindrical shell 1 upper end, top cover 11 is by rivet 15 fixedly fireproof material layer 12, thermal insulation layer 13 successively, and when this structure can prevent effectively that fire from taking place, thereby flare is up run helter-skelter and made fire spreading.Louvre 14 on the top cover 11 can dispel the heat when operate as normal, and when breaking out of fire, the fireproof material layer 12 of top cover 11 1 sides is burned, the fire proofing material of fireproof material layer 12 the insides expands because of being heated, because stopping of thermal insulation layer 13, the fire proofing material that expands is extruded to the slit between louvre 14 and fireproof material layer 12 and cylindrical shell 1 inwall, and louvre 14 and slit be because of the expansion blocking of fire proofing material, thereby prevents spreading of the intensity of a fire.Louvre 14 and rivet 15 are arranged on the top cover 11 ringwise equably, make that the expansion of fire proofing material is more even, and the heat-resistant time after the expansion is longer.
And the top cover 11 that cylindrical shell 1 top is provided with is one-body molded with cylindrical shell 1, can prevent that fireproof material layer 12 breaks away from the cylindrical shell 1 of optically focused Down lamp under the effect of the high velocity air that produces because of burning, thereby make fireproof material layer 12 be fixed on all the time in the cylindrical shell 1, flare can not spread from cylindrical shell 1 in the short time outward, reaches the effect that prolongs the fire prevention time.
The utility model has been placed cableties 4 on electric wire 3, can be so that electric wire 3 be vertical with cylindrical shell 1 bottom surface, and the lamp holder 2 of outwarding winding, it is sagging that lamp holder 2 and bulb 5 get final product nature, and the lamp holder 2 of packing into then only needs vertically up to promote lamp holder 2 to get final product, installing/dismounting is convenient, quick.Because this kind setting need not long electric wire 3, electric wire 3 can not shorten the life-span because of bending for a long time in the cylindrical shell 1 of high temperature, has therefore improved the whole service life of optically focused Down lamp.
Above-described only is the preferred implementation of the utility model optically focused Down lamp; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
