Abstract

A fireproofing lamp comprises a frame plate (1) and a barrel cover (2) installed on the frame plate (1). A baffle (3) is arranged on at least one side of the outside of the barrel cover (2). Expandable fireproofing materials (4) are arranged on the outside of the barrel cover (2). The frame plate (1) is fixed on a cross beam of a suspension ceiling of a house by a slide rail on the frame plate (1) generally. When there is a fire, the expandable fireproofing materials (4) expand when meeting fire and heat, and a carbonization layer is formed on the surface of the baffle (3), so as to prevent the heat or flame from radiating onto the wooden cross beam via the barrel cover (2). The fireproofing lamp avoids the radiation from being affected when the lamp is used in a normal manner, and prevents the fire from spreading in an effective manner when there is a fire.

Description

防火灯具  Fire protection lamp
【技术领域】[Technical Field]
本实用新型涉及照明领域，尤其是指一种具有防火功能的嵌入式灯具。The utility model relates to the field of illumination, in particular to a recessed lamp with fireproof function.
【背景技术】【Background technique】
现代室内设计装修或家居照明、办公照明等场合现在一般会要求使用嵌入式防火灯具，最早期的嵌入式防火灯具在灯具罩体上开设开口作为散热用途，并在开口附近设置膨胀材料，当遇到火灾事故，膨胀材料遇火膨胀封闭该开口。膨胀材料起始膨胀温度为摄氏180度左右，完全膨胀温度为摄氏300度左右。由于气密的要求，现在的灯具很多都被设计成密闭的形式，但火灾发生时，火焰或热量仍然会通过筒罩辐射到天花板后面的木质横梁上，使其炭化或燃烧，大大降低吊顶系统应有的防火功能。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.
灯具附近的木梁在灯具热辐射的作用下会产生碳化、烤焦的现象，被碳化的木材其承重能力大大降低，安全性严重受到影响。在美国的照明安全标准UL263里会对防火灯具安装后附近横梁的温升做测试，不能超过未安装灯具的地方的横梁的5%。现有一般的嵌入式防火灯具很难达到UL263的要求。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.
因此，在此基础上需要提供一种热辐射对附近木材影响少、安全性高的嵌入式灯具。Therefore, on this basis, it is necessary to provide a recessed luminaire with less influence on the nearby wood and high safety.
【发明内容】[Summary of the Invention]
本实用新型的目的在于提供一种对周边热辐射影响相对较少、安全性能较高的防火灯具。The purpose of the utility model is to provide a fireproof lamp with relatively less influence on peripheral heat radiation and high safety performance.
为实现本实用新型目的，提供以下技术方案：
本实用新型提供一种防火灯具，其包括架板和安装在架板上的筒罩，架板一般通过其上的滑轨固定在房屋吊顶的横梁上。该筒罩外至少一侧设有挡板，以及在筒罩外设有膨胀防火材料。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.
在火灾发生时，该膨胀防火材料遇火遇热膨胀，覆盖筒罩外围，防止火苗外窜和热辐射，在不影响灯具平时正常情况的散热的同时，火灾时又有效的保护吊顶系统的防火功能。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. .
作为具体实施方式，在该筒罩外设有相互独立的或者是相连的至少两块挡板，并设有膨胀防火材料，对于安装在横梁附近的灯具有较好的防止热辐射及防火作用。在实际应用中，在筒罩外围至少三面设置有挡板，并设有膨胀防火材料。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.
作为进一步的优化方案，在该筒罩外围四周设有围合的挡板，并设有膨胀防火材料，进一步加强灯具四面的防火性能。更优化的方案是，该挡板在筒罩上方延伸形成顶盖，并设有膨胀防火材料，较全面的设置，是在筒罩四周设有挡板，更在顶部设有顶盖，更进一步的是该挡板和顶盖围成盒型结构将灯具罩住，全面保护灯具，防止热辐射引起附近木梁的碳化、烤焦现象，火灾时有效防火。该顶盖可由挡板在筒罩上方延伸形成。这样，膨胀防火材料的膨胀覆盖效果较好。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.
具体的，该膨胀防火材料设置在筒罩外侧或挡板内侧或挡板外侧，可以是贴在挡板的内表面上或外表面上；或者，该膨胀防火材料设置在筒罩与挡板之间。在该膨胀防火材料遇火遇热膨胀时，会覆盖在筒罩外周围，防止热辐，射减少热辐射对周边木质横梁或易燃品的影响。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.
优选的，挡板围合而成的截面为圆形或方形或菱形或四边形或椭圆形或多边形。Preferably, the cross-section of the baffle is circular or square or diamond or quadrilateral or elliptical or polygonal.
挡板设置的高度可根据实际需要而不同，优选的，其高度可大概等于筒罩高度的三分一或以上，也可等于或高于筒罩高度，挡板较低的实施例可获得较好的散热效果，而挡板较高的实施例的膨胀防火材料的膨胀覆盖效果较好。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.
该挡板可以是密封结构，这样可加强隔热防火效果。也可以在挡板上设置通孔，以获得较好的散热效果，该顶盖上也可以设有通孔，或者在挡板和顶盖上同时设有通孔。挡板与筒罩之间的膨胀防火材料在遇火膨胀后可遮盖这些通孔，同样可获得较好的防火效果。这些通孔可以设计成各种几何形状，例如方形、圆形、三角形、长方形、椭圆形等，可以是规则排列或不规则排列在挡板上。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.
该挡板可以是由防火灯具的架板的部分延伸而成，或者该挡板通过卡扣或铆接方式固定在安装支架上。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.
较佳的，该筒罩内或架板上也同样设有膨胀防火材料，起到加强防火保护作用。Preferably, the inside of the cover or the shelf is also provided with an intumescent fireproof material to enhance the fire protection.
