Abstract

The utility model discloses an inlaid fire-retardant sound-insulation lamp includes a fire-proof cover and a lamp body positioned in the fire-proof cover, the fire-proof cover wall provided with a thermovent, the thermovent having an expansion fire-proof spool, a cover plate pressing on the end face of the expansion fire-proof spool, the expansion fire-proof spool and the cover plate opened with louvers, the thermovent and louver of the expansion fire-proof spool partially communicated, louver of the cover plate and that of the expansion fire-proof spool partially communicated, the thermovent and louver of the cover plate not communicated vertically; when the lamp meets fire, the thermovent will close automatically because of quick expansion of the expansion fire-proof spool, to prevent the fire from spreading out of the lamp body; meanwhile, because the louver and thermovent of the cover plate close vertically, noise will not come out directly but reflected by the fire-proof cover and cover plate for several times after entering through the louver of the cover plate, absorbed by the fire-proof cover, the cover plate and the expansion fire-proof spool and quickly reduces, giving the lamp good sound-insulation function.

Description

Embedded fire-proof sound insulation light fixture

Technical field

The utility model relates to a kind of light fixture.Especially a kind of embedded fire-proof sound insulation light fixture.

Background technology

In the modern Interior finishing, for attractive in appearance and illumination, people install some recessed light fixtures usually on local wallboard such as furred ceiling, Bao Qiang, family property, the intensity of a fire spreads by the perforate of light fixture when preventing that fire from taking place, Chinese patent 200420046935.5 discloses a kind of embedded fire resistant lighting fitting on 07 20th, 2005, thermovent can seal voluntarily because of the prevent fires rapid expansion of sheet of expansion type when meeting fire, and safety guard is isolated the lamp body and the combustibles in the external world fully.But the louvre of the cover plate of light fixture and expansion type fire prevention sheet aligns with the flameproof enclosure thermovent, directly connects, and extraneous noise can be propagated into indoor by louvre.

Summary of the invention

The purpose of this utility model is to provide a kind of fire-proof and thermal-insulation function that has, and possesses the recessed light fixture of sound insulation value simultaneously again.

The utility model is to realize above-mentioned purpose like this:

Embedded fire-proof sound insulation light fixture, comprise flameproof enclosure and be installed in the interior lamp body of flameproof enclosure, on the flameproof enclosure wall thermovent is arranged, expansion type fire prevention sheet is equipped with at the thermovent place, have cover plate to be pressed in above the expansion type fire prevention sheet, expansion type fire prevention sheet and cover plate have and the corresponding louvre of thermovent, and the louvre of expansion type fire prevention sheet partly communicates with thermovent, the louvre of cover plate partly communicates with the louvre of expansion type fire prevention sheet, and the louvre of cover plate does not communicate in vertical direction with thermovent.

The beneficial effects of the utility model are: light fixture thermovent when meeting fire can seal voluntarily because of the prevent fires rapid expansion of sheet of expansion type, prevents that the intensity of a fire from outwards spreading from lamp body; Simultaneously, louvre and the thermovent owing to cover plate seals in vertical direction.Noise can directly not spread out of, but enters after the absorption of the repeatedly reflection of flameproof enclosure and cover plate and flameproof enclosure, cover plate and expansion type fire prevention sheet decays rapidly from the louvre of cover plate, makes light fixture that good sound insulation value be arranged.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a vertical view of the present utility model;

Fig. 2 is a flameproof enclosure schematic diagram of the present utility model;

Fig. 3 is the A-A sectional view of Fig. 1;

Fig. 4 is the structural representation of first kind of embodiment of the utility model;

Fig. 5 is the structural representation of second kind of embodiment of the utility model;

Fig. 6 is the structural representation of the third embodiment of the utility model.

The specific embodiment

Embodiment one, referring to figs. 1 through Fig. 4, embedded fire-proof sound insulation light fixture, comprise flameproof enclosure 1 and lamp body 2, lamp body 2 is made up of light source, lamp socket, and a light source is housed on the lamp socket, equally, lamp body 2 also can comprise a plurality of light sources, and a plurality of light sources can be installed on the lamp socket, also can be installed on a plurality of lamp sockets.Lamp body 2 is fixed on the flameproof enclosure 1 by screw.Cavity 11 is arranged on the flameproof enclosure 1, and thermovent 3 is positioned at the bottom, chamber of cavity 11, and expansion type fire prevention sheet 4 is inlaid in the cavity 11, is pressed with cover plate 5 on the expansion type fire prevention sheet 4, and cover plate 5 is fixedly mounted on the flameproof enclosure 1.Expansion type fire prevention sheet 4 and cover plate 5 have and thermovent 3 corresponding louvres 41,51.By propagating into indoorly with

louvre

41,51 that thermovent 3 directly communicates, the louvre 41 of the expansion type that will dispel the heat during installation fire prevention sheet 4 is opened mutually partially with thermovent 3, and both are communicated at part for fear of ambient noise.Equally, the louvre 51 of cover plate 5 is opened mutually partially with the louvre 41 of expansion type fire prevention sheet 4, and both just partly communicate, and the heat radiation 51 of cover plate 5 is sealed in vertical direction with thermovent 3.If ambient noise enters into the louvre 51 of cover plate 5, then need absorption through the repeatedly reflection between cover plate 5 and the flameproof enclosure cavity 11 and cover plate 5, flameproof enclosure cavity 11 and expansion type fire prevention sheet 4, like this, noise is decayed rapidly, makes light fixture that good sound insulation value be arranged.Although the louvre of cover plate 5 51 seals in vertical direction with thermovent 3, but the louvre 51 of cover plate 5 and thermovent 3 still can form heat dissipation channel by both parts that communicates with the part of the louvre 41 of expansion type fire prevention sheet 4 respectively, and the heat that lamp body 2 is produced can be dispersed into outside the light fixture by this passage.

In order to make light fixture fire-proof and thermal-insulation better, the outer wall of flameproof enclosure 1 is with fire-proof and thermal-insulation pad 6.With reference to Fig. 4, fire-proof and thermal-insulation pad 6 is coated on the outer surface of flameproof enclosure 1, and fire-proof and thermal-insulation pad 6 can play fire prevention and heat insulation effect better.Simultaneously, fire-proof and thermal-insulation pad 6 also has good sound absorption, the performance of sound insulation, reaches better soundproof effect.

Embodiment two, and with reference to Fig. 5, according to different needs, it is the ring-type of " L " shape that fire-proof and thermal-insulation pad 6 can be selected cross sectional shape, and the miscellaneous part of light fixture is identical with embodiment one.

Embodiment three, and with reference to Fig. 6, fire-proof and thermal-insulation pad 6 is circular, and the miscellaneous part of light fixture is identical with embodiment one.
