Abstract

A fireproof lamp comprises a frame plate and a barrel cover. The frame plate is fixed on a cross beam of a ceiling of a house via slide tracks on the frame plate, a baffle plate is disposed on at least one side outside a lampshade, and expansion fireproof materials are disposed on the inner surface or the outer surface of each baffle plate. When in fire hazard, the expansion fireproof materials are expanded when meeting fire and heat, and a thick charring layer is formed on the surface of each baffle plate so as to prevent heat or flame from being radiated onto the wooden cross beam via the barrel cover to burn or char the cross beam and shorten fireproof time of a ceiling system. The fireproof lamp can dissipate heat without affecting utilization at ordinary times, and effectively stops fire from spreading when in fire hazards.

Description

A kind of fire resistant lighting fitting
[technical field]
The present invention relates to lighting field, refer in particular to a kind of recessed light fixture with fire-proof function.
[background technology]
Modern interior Design finishing or occasions such as lighting of home, office lighting generally can require to use embedded fire resistant lighting fitting now, the embedded fire resistant lighting fitting of earliest period is offered opening as the heat radiation purposes on the light fixture cover body, and expanding material is set near opening, when running into fire incident, expanding material is met this opening of fire expansion sealing.The expanding material initial expansion temperature is about 180 degree Celsius, and the complete expansion temperature is about 300 degree Celsius.Because airtight requirement, present light fixture much all is designed to airtight form, but fire is when taking place, and flame or heat still can be radiated on the wooden crossbeam of ceiling back by the tube cover, make its charing or burning, reduce the due fire-proof function of ceiling system greatly.
Near the light fixture wooden frame can produce carbonization, burned phenomenon under the thermal-radiating effect of light fixture, its weight capacity of the timber that is carbonized reduces greatly, and security seriously is affected.In that can being installed fire resistant lighting fitting in the lighting safety standard UL263 of the U.S. near the back, the temperature rise of crossbeam does test, and can not be above 5% of the crossbeam in the place that light fixture is not installed.Existing general embedded fire resistant lighting fitting is difficult to reach the requirement of UL263.
Therefore, need on this basis to provide a kind of heat radiation near timber influence less, safe recessed light fixture.
[summary of the invention]
The object of the present invention is to provide a kind of, fire resistant lighting fitting that security performance higher less relatively to peripheral heat radiation influence.
For realizing the object of the invention, provide following technical scheme:
A kind of fire resistant lighting fitting, it comprises frame plate and tube cover, frame plate generally is fixed on the crossbeam of house furred ceiling by the slide rail on it, at least one side is provided with baffle plate lampshade outside, within the baffle plate surface upward or outer surface be provided with expansion fireproof material.When fire took place, this expansion fireproof material was met fire and is met thermal expansion, covered the lampshade periphery, prevented that flare from scurrying and heat radiation outward, when not influencing the light fixture heat radiation of normal condition at ordinary times, effectively protected the fire-proof function of ceiling system during fire again.
In actual applications, at least three faces are provided with baffle plate in the lampshade periphery, are being provided with expansion fireproof material on the inner surface of baffle plate or on the outer surface.This expansion fireproof material is attached on the baffle inner wall or on the outer wall, when this expansion fireproof material is met the thermal expansion of fire chance, can covers the lampshade outer surface, prevents hot spoke, penetrates and reduces the influence of heat radiation to wooden crossbeam of periphery or inflammable thing.More comprehensively being provided with, is to be provided with baffle plate around lampshade, more is provided with top cover at the top, further is that this baffle plate and top cover surround case type structures light fixture is covered.
In the time of at least two baffle plates, baffle plate can be continuous or separate.Preferred embodiment is to be provided with the baffle plate that surrounds all around in the lampshade periphery.
The aforementioned shape that baffle plate surrounded in the peripheral setting of lampshade can be designed to circle or quadrangle or polygon, the height that baffle plate is provided with can be according to actual needs and different, can probably equal three minutes one of the lampshade height or more than, can be equal to or higher than the lampshade height, the embodiment that baffle plate is lower can obtain better radiating effect, and the expansion coverage effect of the expansion fireproof material of the higher embodiment of baffle plate is better.
Can be provided with through hole on this baffle plate, to obtain better radiating effect, the expansion fireproof material between baffle plate and the lampshade can hide these through holes after meeting the fire expansion, can obtain flameproof effect preferably equally.These through holes can be designed to various geometries, for example square, circular, triangle, rectangle, ellipse etc. can be regularly arranged or irregular alignment on baffle plate.
Can be provided with top cover on lampshade, this top cover is provided with through hole, perhaps is provided with through hole on baffle plate and top cover simultaneously.This top cover is to be extended by side board to form.
This baffle plate can be to be extended by the part of the frame plate of fire resistant lighting fitting to form, and perhaps this baffle plate is fixed on the mounting bracket by buckle or riveted joint mode.
Preferable, be provided with expansion fireproof material too in this cover or on the frame plate, play and strengthen the flameproof protection effect.
The contrast prior art, the present invention has the following advantages:
Fire resistant lighting fitting of the present invention is when fire takes place, this expansion fireproof material is met fire and is expanded, and forms thick charring layer on baffle surface, thereby prevents that heat or flame are radiated on the wooden crossbeam by the tube cover, cause crossbeam burning or charing, cause the shortening of the fire prevention time of ceiling system.The heat radiation of fire resistant lighting fitting of the present invention when not influencing light fixture and use at ordinary times, being provided with of its baffle arrangement and expansion fireproof material can effectively stop the influence of heat radiation near the timber light fixture, reduce Wood carbonization, burned phenomenon, do not influence the load-bearing property of floor, effectively stop fire spreading during fire again, security is improved.
