Abstract

Embedded type fireproofing light fixture is composed of lamp body and fireproofing cover. The lamp body is installed inside cover produced from refractory materials. There are thermovents on wall of the fireproofing cover. Expanding typed fireproofing pieces made from fireproofing materials are installed on thermovents. There are heat elimination holes on the fireproofing pieces, on places corresponding to thermovents, or on between the fireproofing piece and the fireproofing cover. Normal heat elimination is carried out through thermovents. In case of fire, the fireproofing pieces expand rapid to close down thermovents. The fireproofing cover insulates lamp body from external inflammable so as to prevent fire from spreading.

Description

Embedded fire resistant lighting fitting
Technical field
The present invention relates to a kind of light fixture, especially a kind of embedded fire resistant lighting fitting.
Background technology
In the modern Interior finishing, for attractive in appearance and illumination, people are usually at furred ceiling, the bag wall, on the wallboard in family property or the like place some recessed light fixtures are installed, fire spreading when preventing that fire from taking place, what the wallboard in above place used all is fire-proof board, the surface of fire-proof board is a fireprotection layer, the intermediate layer generally but is flammable, necessary perforate on PLASTIC LAMINATED when recessed light fixture is installed, and existing recessed light fixture does not possess the function that stops fire spreading, so just cause the flare can be by the ignite intermediate layer of PLASTIC LAMINATED of these recessed light fixtures, PLASTIC LAMINATED just play due anti-fire action yet, more seriously, often there are a large amount of combustibles in furred ceiling and the bag wall interlayer and the inside of family property, as yoke, electric wire, clothing etc., flare these combustibles that in a single day ignite, the intensity of a fire is with rapid spread.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this invention is to provide a kind of embedded fire resistant lighting fitting that prevents the fire spreading function that has.
The technical solution adopted for the present invention to solve the technical problems is:
Embedded fire resistant lighting fitting, comprise lamp body, lamp body is installed in the flameproof enclosure of being made by refractory material, on the cover wall of flameproof enclosure thermovent is arranged, expansion type fire prevention sheet is equipped with at the thermovent place, on expansion type fire prevention sheet, the position of thermovent correspondence or between expansion type fire prevention sheet and flameproof enclosure wall louvre is arranged; Expansion type fire prevention sheet prolongs the burning material by fire prevention to be made, and expansion type fire prevention sector-meeting is expanded rapidly when meeting fire, thereby makes the thermovent sealing.
The invention has the beneficial effects as follows: lamp body of the present invention is installed in the flameproof enclosure of being made by refractory material, thermovent is arranged on the flameproof enclosure, be equipped with by fire prevention and prolong the expansion type fire prevention sheet that the burning material is made at the thermovent place, light fixture can normally dispel the heat by thermovent under general case, guaranteed the life-span of light fixture and light source thereof, thermovent can seal voluntarily because of the prevent fires rapid expansion of sheet of expansion type when meeting fire, and flameproof enclosure is isolated the lamp body and the combustibles in the external world fully, can prevent that the intensity of a fire from outwards being spread by lamp body.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of first kind of embodiment of the present invention;
Fig. 2 is the structural representation of second kind of embodiment of the present invention;
Fig. 3 is the structural representation of the third embodiment of the present invention.
The specific embodiment
Fig. 1 has provided a kind of structural representation of embedded fire resistant lighting fitting, among the figure, lamp body 1 is made up of light source, lamp socket and lampshade, and lamp socket is inlaid on the lampshade, and a light source is housed on the lamp socket, lamp body 1 is fixedly mounted in the flameproof enclosure 2 made of iron by screw, have wire hole on the cover wall of flameproof enclosure 2, electric wire 9 passes wire hole light source is connected in the external circuitry, and wire hole seals with fire proofing simultaneously, equally, electric wire 9 also can directly pass and prevent that fire hole links to each other with external circuitry; One cavity 6 is arranged at the top of flameproof enclosure 2, expansion type fire prevention sheet 4 is flush-mounted in the cavity 6, the cover plate 7 that is fixed on the lampshade is pressed on the expansion type fire prevention sheet 4, and a thermovent 3 is arranged on the bottom surface of cavity 6, has a louvre 5 on the expansion type fire prevention sheet 4, louvre 5 is positioned at the top of thermovent 3, spring clip 8 is housed on the flameproof enclosure 2, is used for lamp installation at sheet material, in addition, on the lampshade a plurality of lamp sockets can be installed, also a plurality of light sources can be installed on each lamp socket.Because thermal current rises, so thermovent 3 places the top light fixture of being more convenient for to dispel the heat; Expansion type fire prevention sheet 4 prolongs the burning material by fire prevention to be made, expansion rapidly when chance is fiery, thus louvre 5 is sealed, so just can stop fire spreading to combustibles on every side; Because expansion type fire prevention sheet 4 is positioned at cavity, and cover plate 7 is housed on it, so just make expansion type fire prevention sheet 4 when meeting fire lateral expansion take place mainly, the speed that louvre 5 is closed is also just faster.CP-25, the CS-195 that the burning material can be selected Minnesota Mining and Manufacturing Company for use, CPS-AA546 of U.S. Acnielsen Ltd. or the like are prolonged in the fire prevention of expansion type fire prevention sheet 4.
Fig. 2 has provided the structural representation of another kind of embedded fire resistant lighting fitting, and lamp body 1 is made up of light source and lamp socket among the figure, and lamp body 1 is positioned at flameproof enclosure 2, and flameproof enclosure 2 had both played the effect that prevents fire spreading, plays the effect of lampshade again, and is simple in structure, saves cost; Have thermovent 3 on the roof of flameproof enclosure 2 simultaneously, expansion type fire prevention sheet 4 is inlaid in the thermovent 3, has a plurality of louvres on the expansion type fire prevention sheet 4, can improve the radiating efficiency of light fixture like this.
Fig. 3 has provided the structural representation of another kind of embedded fire resistant lighting fitting, have a plurality of thermovents 3 among the figure on the roof of flameproof enclosure 2, expansion type fire prevention sheet 4 is installed in the upper surface of the roof of flameproof enclosure 2 by screw, and on expansion type fire prevention sheet 4, all there is louvre 5 at the place, top of each thermovent 3, a plurality of thermovents are set like this will help the heat radiation of light fixture more, also have thermovent 3 on the sidewall of flameproof enclosure 2 simultaneously, expansion type fire prevention sheet 4 is inlaid in the thermovent 3, form louvre 5 between the edge of expansion type fire prevention sheet 4 and the edge of thermovent 3, when lamp needs laterally to install, as be installed in when wrapping in the wall, the thermovent that can make sidewall can more help heat radiation up like this.
In addition, the invention also has some other embodiment, and as in the middle of first kind of above-mentioned embodiment, the cavity on the flameproof enclosure also can be arranged to the protruding chamber of evagination, and the fire prevention sheet is installed in the protruding chamber, and cover plate then be the supporting plate of sheet picking-up of will preventing fires; Perhaps in the middle of the third above-mentioned embodiment, the fire prevention sheet can be installed in lower surface of roof or the like.
