Abstract

A fireproof lamp, comprising a frame plate (1) and a cylinder cover (2) mounted on the frame plate (1); the cylinder cover (2) is provided with a baffle (3) on at least one outer side; the cylinder cover (2) is provided with an intumescent fireproof material (4) on the outside; the frame plate (1) is fixed on the cross beam of a house ceiling via a slide track on the frame plate. When a fire occurs, the intumescent fireproof material (4) expands upon exposure to fire or heat, so that a thick charring layer is formed on the surface of the baffle (1), thus preventing the heat or fire from radiating to the wooden cross beam via the cylinder cover, because the radiation may burn or char the cross beam and shorten the fireproof life of the ceiling system. The fireproof lamp does not affect the heat dissipation during normal use.

Description

Fire protection lamp

[Technical Field]

The utility model relates to the field of illumination, in particular to a recessed lamp with fireproof function.

【Background technique】

Modern interior design or home lighting, office lighting and other occasions now generally require the use of embedded fire-fighting luminaires. The earliest embedded fire-fighting luminaires have openings on the luminaire cover for heat dissipation and are provided with expansion material near the opening. In the event of a fire, the intumescent material expands to close the opening in the event of a fire. The initial expansion temperature of the expanded material is about 180 degrees Celsius, and the full expansion temperature is about 300 degrees Celsius. Due to the requirements of airtightness, many of the current lamps are designed in a closed form, but when a fire occurs, the flame or heat will still radiate through the cover to the wooden beam behind the ceiling, causing it to charify or burn, greatly reducing the ceiling system. The fire protection function should be.

The wooden beams near the lamps will produce carbonization and scorching under the action of the heat radiation of the lamps. The carbonized wood has a greatly reduced bearing capacity and the safety is seriously affected. In the US lighting safety standard UL263, the temperature rise of the nearby beam after the installation of the fire protection lamp shall be tested, and shall not exceed 5% of the beam of the place where the lamp is not installed. Existing general embedded fire protection lamps are difficult to meet the requirements of UL263.

Therefore, on this basis, it is necessary to provide a recessed luminaire with less influence on the nearby wood and high safety.

[Summary of the Invention]

The purpose of the utility model is to provide a fireproof lamp with relatively less influence on peripheral heat radiation and high safety performance.

In order to achieve the object of the present invention, the following technical solutions are provided:
The utility model provides a fireproof lamp, which comprises a shelf plate and a cylinder cover mounted on the shelf plate. The shelf plate is generally fixed on the beam of the ceiling of the house through the slide rails thereon. The baffle is provided with a baffle on at least one side of the cover, and an expanded fireproof material is disposed outside the cover.

In the event of a fire, the intumescent fire-retardant material expands in the event of heat, covering the periphery of the casing, preventing the flames from igniting and radiating heat, and effectively protecting the fire-proof function of the ceiling system while not affecting the normal heat dissipation of the lamp. .

As a specific embodiment, at least two baffles are provided independently or connected to each other outside the cover, and an expansion fireproof material is provided, which has better heat radiation prevention and fire prevention effects for the lamp installed near the beam. In practical applications, at least three sides of the outer periphery of the cover are provided with baffles, and an intumescent fireproof material is provided.

As a further optimization scheme, a surrounding baffle is arranged around the periphery of the cover, and an expansion fireproof material is provided to further enhance the fireproof performance of the four sides of the lamp. A more optimized solution is that the baffle extends over the cover to form a top cover and is provided with an expanded fireproof material. The more comprehensive arrangement is provided with a baffle around the cover and a top cover at the top, further The baffle and the top cover are enclosed in a box-type structure to cover the luminaire, and the luminaire is fully protected to prevent carbonization and charring of the nearby wooden beams caused by heat radiation, and effective fire prevention during fire. The top cover may be formed by a baffle extending over the cover. Thus, the expansion covering effect of the expanded fireproof material is better.

Specifically, the intumescent fireproof material is disposed on the outer side of the cover or on the inner side of the baffle or on the outer side of the baffle, and may be attached to the inner surface or the outer surface of the baffle; or the expanded fireproof material is disposed on the cover and the baffle between. When the expanded fireproof material expands in the event of fire, it will cover the outer periphery of the cylinder cover to prevent heat radiation, and reduce the influence of heat radiation on the surrounding wooden beams or flammable products.

Preferably, the cross-section of the baffle is circular or square or diamond or quadrilateral or elliptical or polygonal.

The height of the baffle plate may be different according to actual needs. Preferably, the height may be approximately one third or more of the height of the cover, or may be equal to or higher than the height of the cover. The lower baffle embodiment can obtain better. The heat dissipation effect, while the expanded fireproof material of the embodiment with the higher baffle has better expansion coverage effect.

The baffle can be a sealed structure to enhance the thermal insulation effect. It is also possible to provide a through hole on the baffle for better heat dissipation. The top cover may also be provided with a through hole, or a through hole may be provided on the baffle and the top cover at the same time. The intumescent fireproof material between the baffle and the cover can cover the through holes after being inflated by fire, and a better fireproof effect can also be obtained. These through holes can be designed in various geometric shapes, such as square, circular, triangular, rectangular, elliptical, etc., which can be regularly arranged or irregularly arranged on the baffle.

The baffle may be formed by a portion of the shelf of the fire protection luminaire, or the baffle may be fastened to the mounting bracket by snapping or riveting.

Preferably, the inside of the cover or the shelf is also provided with an intumescent fireproof material to enhance the fire protection.

Compared with the prior art, the utility model has the following advantages:
The baffle structure of the fireproof lamp of the utility model and the setting of the expanded fireproof material can effectively block the influence of the heat radiation on the wood near the lamp, reduce the phenomenon of carbonization and charring of the wood, and do not affect the bearing performance of the floor, and the expansion occurs in the event of a fire. The fireproof material expands in the fire and forms a thick carbonized layer on the surface of the baffle to prevent heat or flame from radiating through the cover to the wooden beam, causing the beam to burn or carbonize, resulting in shortening of the fireproof time of the ceiling system. The new fireproof luminaire can effectively prevent the spread of fire in the event of fire and improve safety.
