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 is installed on the ceiling, when ceiling top infiltration or when dust is arranged, can down ooze or falls down by the slit between cylindrical shell and the ceiling, makes indoor environment moist or make the room air muddiness.The noise of while ceiling top is transmitted to indoor easily by the slit, influence is lived and experienced.The optically focused Down lamp in the course of the work, heat radiation is still waiting further raising.When breaking out of fire, flare is up scurried rapidly, and the structure that plays anti-fire action breaks away from the cylindrical shell of optically focused Down lamp under the high velocity air that produces because of burning, lose the fireproof function.
The utility model content
The purpose of this utility model is to integrate sound insulation, waterproof, fire prevention in order to provide a kind of, prevent dust, sealing and the good optically focused Down lamp of heat dispersion.
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 the lamp holder in the cylindrical shell, the electric wire that connects lamp holder, described lamp holder upper end is provided with the fire prevention fin of band louvre, described fire prevention fin comprises and the circular material layer of cylindrical shell coupling and the thermal insulation layer of material layer both sides, described cylinder top is provided with and the integrated top cover of described cylindrical shell, after radially extending, described cylindrical shell bottom surface is bent upwards the formation protuberance, described protuberance and cylindrical shell bottom surface form groove, and described groove is provided with the sealing ring with the groove coupling.
More excellent, described louvre circular array is on the fire prevention fin.
More excellent, described sealing ring is provided with circular material layer.
And, be embedded with O shape circle between inboard, described cylindrical shell bottom surface and the bulb.
The fire prevention fin that the utility model is provided with in lamp holder upper end, in the time of can preventing effectively that fire from taking place, thereby flare is up run helter-skelter and is made fire spreading.Louvre on the fire prevention fin can dispel the heat when operate as normal, and when breaking out of fire, the material layer of fire prevention fin the inside is burned, the fire proofing material of 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 fire prevention fin and the cylindrical shell, and louvre and slit be because of the expansion blocking of fire proofing material, thereby prevents spreading of the intensity of a fire.The louvre circular array makes that the expansion of fire proofing material is more even on the fire prevention fin, the heat-resistant time after the expansion is longer.The top cover that cylinder top is provided with, the fin that can prevent to prevent fires breaks away from the cylindrical shell of optically focused Down lamp under the effect of the high velocity air that produces because of burning, make the fire prevention fin be fixed on all the time on the interior lamp holder of cylindrical shell, the height of fire prevention fin in cylindrical shell on the lamp holder can be regulated according to the height of bulb, during breaking out of fire, flare can not spread from cylindrical shell in the short time outward, reaches the effect that prolongs the fire prevention time.
When ceiling down seeped water, the protuberance of the utility model cylindrical shell bottom surface, the sealing ring on the cylindrical shell bottom recesses and the circle of the O shape between cylindrical shell inboard and the lamp holder can prevent that water droplet from down permeating, even can play sound insulation, dustproof effect.Circular material layer on the sealing ring, when breaking out of fire, expanded by heating is blocked the slit between protuberance and the ceiling, prevents that flare from spreading to ceiling.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is an internal structure cutaway view of the present utility model;
Fig. 3 is the enlarged diagram of A part among Fig. 2.
Among the figure: 1, cylindrical shell; 11, top cover; 12, protuberance; 13, groove; 14, sealing ring, 15, O shape circle; 2, lamp holder; 3, electric wire; 4, fire prevention fin; 41, louvre; 42, material layer; 43, thermal insulation layer; 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, comprise whole cylindrical cylindrical shell 1, be placed in lamp holder 2 and bulb 5 in the cylindrical shell 1, connect the electric wire 3 of lamp holder 2, lamp holder 2 upper ends are provided with the fire prevention fin 4 of band louvre 41, and louvre 41 circular array are on fire prevention fin 4.Fire prevention fin 4 comprises the thermal insulation layer 43 of material layer 42 and material layer 42 both sides.Cylindrical shell 1 top is provided with and described cylindrical shell 1 integrated fin 4 top cover 11 of play outward that prevents to prevent fires, be bent upwards after radially extend cylindrical shell 1 bottom surface and form protuberance 12, protuberance 12 forms groove 13 with the cylindrical shell bottom surface, place sealing ring 14 on the groove 13 with groove 13 couplings, sealing ring 14 is provided with the circular material layer 42 that plays anti-fire action, is embedded with O shape circle 15 between the inboard, bottom surface of cylindrical shell 1 and the bulb 5.
The fire prevention fin 4 that the utility model is provided with in lamp holder 2 upper ends, in the time of can preventing effectively that fire from taking place, thereby flare is up run helter-skelter and is made fire spreading.Louvre 41 on the fire prevention fin 4 can dispel the heat when operate as normal, and when breaking out of fire, the material layer 42 of fire prevention fin 4 the insides is burned, the fire proofing material of material layer 42 the insides expands because of being heated, because stopping of thermal insulation layer 43, the fire proofing material that expands is extruded to the slit between louvre 41 and fire prevention fin 4 and the cylindrical shell 1, and louvre 41 and slit be because of the expansion blocking of fire proofing material, thereby prevents that the intensity of a fire from spreading outward by louvre 41.Louvre 41 circular array make that the expansion of fire proofing material is more even on fire prevention fin 4, the heat-resistant time after the expansion is longer.The top cover 11 that cylindrical shell 1 top is provided with, the fin 4 that can prevent to prevent fires 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, make fire prevention fin 4 be fixed on all the time on the lamp holder 2 in the cylindrical shell 1, the height of fire prevention fin 4 in cylindrical shell 1 on the lamp holder 2 can be regulated according to the height of bulb 5, during breaking out of fire, flare can not spread from cylindrical shell 1 in the short time outward, reaches the effect that prolongs the fire prevention time.
When ceiling down seeps water, the sealing ring 14 on the protuberance 12 of the utility model cylindrical shell 1 bottom surface, cylindrical shell 1 bottom recesses 13 and cylindrical shell 1 inboard with lamp holder 2 between O shape enclose 15 and can prevent that water droplet from down permeating, even can play sound insulation, dustproof effect.Circular material layer 42 on the sealing ring 14, when breaking out of fire, expanded by heating is blocked the slit between protuberance 12 and the ceiling, prevents that flare from spreading to ceiling.
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.
