Embedded lamp

Abstract

The invention discloses an embedded lamp with a lamp body mounted in a fire-proof cover, the fire-proof cover is composed of a metal layer envelopping a fire-proof heat insulation layer or coated with the fire-proof heat insulation layer, the fire-proof cover can prevent fire propagation from the lamp body to circumambience, and the fire-proof heat insulation layer would not make a temperature of an outer surface of the fire-proof cover be excessive high so as to result burning of some tinder around the fire-proof cover, a cover wall of the fire-proof cover is provided with a heat dispersion opening mounted with an expanded type fire-proof sheet, a heat dispersion hole is arranged at a position of the expanded type fire-proof sheet corresponding to the heat dispersion opening and/or the heat dispersion hole is arranged between an edge of the expanded type fire-proof sheet and an edge of the heat dispersion opening, so that the lamp can performing heat dispersion normally at a common condition, when encountering a fire, the heat dispersion opening can be automatically closed by rapid expansion of the expanded type fire-proof sheet, the fire-proof cover completely insulates the lamp from outside tinder, thereby preventing the tinder propagation from the lamp to outside.

Description

technical field [0001] The invention relates to a lamp, especially an embedded lamp. Background technique [0002] In modern interior decoration, for the sake of beauty and lighting, people usually install some embedded lamps on the wall panels of suspended ceilings, walls, furniture and other places. In order to prevent the fire from spreading when a fire occurs, the wall panels in the above places are all fireproof The surface of the fireproof board is a fireproof layer, but the middle layer is combustible. When installing embedded lamps, holes must be opened on the fireproof board. However, the existing embedded lamps do not have the function of preventing the spread of fire, which causes flames The middle layer of the fireproof board can be ignited through these embedded lamps, and the fireproof board will not be able to play its due fireproof effect; in addition, there are often a large number of flammable materials in the interlayer of the suspended ceiling and the cla...
