<p>An embedded fire-retardant ceiling lamp comprises a lampshade (1), a light socket (5) and a lamp bulb (6) disposed inside the lampshade (1), and a junction box (3) being fixed outside the lampshade (1) through a support (13). A through hole (11) is opened at a sidewall of the lampshade (1), and a fire-retardant intumescent material is disposed on the surface of the sidewall of the lampshade (1). The embedded fire-retardant ceiling lamp solves the problem of local excessively high temperature as heat fails to dissipate from the top of the lampshade (1) being covered by a building thermal insulation material. Heat of the light socket (5) can dissipate via the through hole (11), and meanwhile, the fire-retardant intumescent material is disposed at the outer surface of the lampshade (1), and intumesces to cover the through hole (11) upon exposure to fire, thereby effectively preventing fire from spreading.</p> |
