Abstract
The utility model discloses fire resistant lighting fitting, comprise one for holding the Lamp cup of lamp, described Lamp cup is provided with one or more long and narrow passage, and described passage communicates with the inner chamber of Lamp cup.The utility model has following beneficial effect: structure is simple, and the heat that the lamp in Lamp cup can be enable to produce fully is discharged to the outside of Lamp cup, can block flame simultaneously and spread to Lamp cup outside from Lamp cup inner chamber.
Description
Technical field
The utility model relates to lighting field, is specifically related to a kind of fire resistant lighting fitting.
Background technology
British Standard 476 the 21st means suitable, on ceiling panel, mounted lamp must not damage the fire protecting performance of these panels, and a kind of method solving this problem uses fire resistant lighting fitting.There is now the flameproof effect that some recessed light fixtures reach certain by arranging Lamp cup outside light fixture, the Lights section of light fixture, lamp ring structure and radiator are all placed in Lamp cup, and in order to dispel the heat, through hole is offered at the top of Lamp cup, but the heat-sinking capability of through hole is limited, the heat accumulation of light fixture is in Lamp cup, radiating effect is very poor, easily cause light fixture overheated and the hair gathered that burns out or ignite, the combustibles such as dust, and because Lamp cup top has through hole, when breaking out of fire, flare is easily leapt up out from through hole, cause fire spreading, therefore the light fixture of these structures can not effectively be prevented fires.
Utility model content
Technical problem to be solved in the utility model is to provide that structure is simple, the fire resistant lighting fitting of good heat dissipation effect.
The technical solution realizing the utility model object is: fire resistant lighting fitting, comprising one for holding the Lamp cup of lamp, it is characterized in that: described Lamp cup is provided with one or more long and narrow passage, and described passage communicates with the inner chamber of Lamp cup.
Described Lamp cup top is provided with top board, and described passage radial direction is located on top board, and Lamp cup top is provided with the passage communicated with passage.
Described top board adopts fireproofing and heat resistant material.
Described Lamp cup sidewall periphery is provided with fire prevention body, and described passage radial direction is located on fire prevention body, and Lamp cup sidewall is provided with the passage communicated with passage.
Fire prevention body adopts fireproofing and heat resistant material.
Described passage is bending.
The utility model fire resistant lighting fitting has following beneficial effect: structure is simple, and the heat that the lamp in Lamp cup can be enable to produce fully is discharged to the outside of Lamp cup, can block flame simultaneously and spread to Lamp cup outside from Lamp cup inner chamber.

Detailed description of the invention
Embodiment one
As depicted in figs. 1 and 2, fire resistant lighting fitting, comprise one for holding the Lamp cup 1 of lamp, described Lamp cup 1 top is provided with top board 2, and described top board 2 adopts fireproofing and heat resistant material, and described top board 2 is provided with the narrow bending passage 2.1 of radial equipartition, the top of described Lamp cup 1 is provided with passage 1.1, described passage 2.1 communicates with passage 1.1, then passage 2.1 communicates with the inner chamber 1.2 of Lamp cup 1, thus the heat that the lamp in Lamp cup is produced distributes.
Embodiment two
As shown in Figure 3 and Figure 4, fire resistant lighting fitting, comprises one for holding the Lamp cup 1 of lamp, the sidewall periphery of described Lamp cup 1 is provided with fire prevention body 3, fire prevention body 3 adopts fireproofing and heat resistant material, and described fire prevention body 3 is provided with the narrow passage 3.1 of radial equipartition, and described passage is in bending or inclination.Described Lamp cup 1 sidewall is provided with passage 1.3, and described passage 3.1 communicates with passage 1.3, then passage 3.1 communicates with the inner chamber 1.2 of Lamp cup 1, thus the heat that the lamp in Lamp cup is produced distributes.
Embodiment three
As shown in Figure 5, embodiment one and embodiment two are combined.
The heat that passage capable of being in sum enables the lamp in Lamp cup produce fully is discharged to the outside of Lamp cup, can block flame simultaneously and spread to Lamp cup outside from Lamp cup inner chamber.
The circular in cross-section of described passage or oval or polygon, the inscribed circle diameter of its cross section is 3mm ~ 5mm.
