Abstract
The utility model discloses a light transmission fireproof lamp, which comprise a lamp ring, a light transmission sheet and a light source; the light source is installed in the lamp ring. which is characterized in that: the light transmission sheet is a heatproof light transmission sheet clung to the inner flange of the lamp ring; the light transmission sheet is not easy to be burned out, and since the light transmission sheet is clung to the inner flange of the lamp ring, the fire can be preventing from spreading out from the light fixture. The utility model needs no fireproof material between the transmission sheet and the lamp ring inner flange and on the transmission sheet edge and side; therefore, achieves the advantages of simple structure and low cost.
Description
Technical field
The utility model relates to a kind of printing opacity fire prevention lamp that has.
Background technology
Existing fire resistant lighting fitting is varied, and it generally all comprises light source, light transmission piece and lamp ring, and light source is installed in the lamp ring, is positioned at the top of light transmission piece, and light transmission piece is fixed in the lamp ring by jump ring or filler ring.When breaking out of fire, outwards to spread from light fixture in order to prevent the intensity of a fire, the place generally all is equipped with fire proofing material near between the inward flange of described light transmission piece and lamp ring or light transmission piece edge, the sides etc.Such fitting structure more complicated that seems, manufacturing cost is than higher.
Summary of the invention
The technical scheme that solves
In order to address the above problem, the purpose of this utility model is to provide a kind of simple in structure, that cost is low and fire resistant lighting fitting that can effectively prevent fire spreading.
Technical scheme
Fire resistant lighting fitting comprises lamp ring, light transmission piece and light source, and light source is installed in the lamp ring, and described light transmission piece is the heatproof light transmission piece, and the inward flange of heatproof light transmission piece and lamp ring is close together.
Wherein, described lamp is equipped with outward flange.
Wherein, described outward flange is provided with fire proofing material.
Beneficial effect
Because described light transmission piece is the heatproof light transmission piece, the inward flange of heatproof light transmission piece and lamp ring is close together; Even breaking out of fire, light transmission piece also are not easy to be burnt out, and the inward flange of light transmission piece and lamp ring is close together, thereby prevents that effectively the intensity of a fire from outwards spreading from light fixture.The utility model saved between the inward flange of light transmission piece and lamp ring or
Therefore near the fire proofing material in place light transmission piece edge, the side etc. the utlity model has advantage simple in structure, that cost is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of first kind of embodiment of the utility model;
Fig. 2 is the structural representation of second kind of embodiment.
The specific embodiment
With reference to Fig. 1, fire resistant lighting fitting comprises lamp ring 1, light transmission piece 2 and light source 3, and light source 3 is installed in the lamp ring 1, it is characterized in that: described light transmission piece 2. is the heatproof light transmission piece, and the inward flange 4 of heatproof light transmission piece and lamp ring 1 is close together.Even breaking out of fire, light transmission piece 2 also are not easy to be burnt out, and the inward flange 4 of light transmission piece 2 and lamp ring 1 is close together, thereby prevents that effectively the intensity of a fire from outwards spreading from light fixture.The utility model has saved between the inward flange 4 of light transmission piece 2 and lamp ring 1 or near local fire proofing material light transmission piece 2 edges, the side etc., therefore the utlity model has advantage simple in structure, that cost is low.
In order to strengthen fire-proof function of the present utility model, described lamp ring 1 is provided with outward flange 5.Certainly, can fire proofing material 6 be installed on described outward flange 5 and further strengthen fire-proof function of the present utility model.
Wherein, described light transmission piece 2 is fixed on the below of lamp ring 1 inward flange 4 by anti-Collodion.In addition, also can light transmission piece be close to the below of inward flange 4 by jump ring 7 (as Fig. 2) or other traditional connector.Certainly, described light transmission piece can be close to the top of lamp ring 1 inward flange 4.
In sum, described fire proofing material 6 is the expansion type fire proofing material.The inflatable seal circle is met fire and will be expanded, and cuts off spreading of the intensity of a fire thereby make lamp ring flange, inflatable seal circle and heatproof light transmission piece three form a tight structure.Wherein, described expansion type fire proofing material is an expansion type silica gel, and its sound insulation, waterproof and fire prevention are better than other fire prevention expanding material again.
