Description
[technical field]
The utility model relates to lighting field, refers in particular to a kind of Embedded LED fire resistant lighting fitting.
[background technology]
Modern interior Design finishing or occasions such as lighting of home, office lighting generally can be used embedded smallpox light fixture; The modal application of embedded smallpox light fixture is mounted in the perforate of having offered on the ceiling; The ceiling of ceiling system much all is common combustible material; Like wooden and plastics etc., if embedded smallpox light fixture is installed on ceiling, the bulb in the light fixture is because the too high ceiling of lighting probably of temperature.In addition; When indoor breaking out of fire; Current recessed light fixture particularly flush type LED lamp does not generally possess fire-proof function; Flare can up be leapt up through the gap between light fixture gap and light fixture and the ceiling so, and high temperature of fire can scorification the wiring board of LED light fixture, leap up out and other inflammable objects on the ceiling that ignites from the light fixture that is damaged more easily.
See also Figure 11, more existing recessed light fixtures reach certain flameproof effect through tube cover 10 is set outside light fixture, and the Lights section 70 of light fixture, lamp ring structure 80 and radiator 90 all place in the tube cover 10; And in order to dispel the heat, above tube cover 10, offer through hole 60, but the heat-sinking capability of through hole is limited; In the narrow space of the heat accumulation of light fixture between tube cover 10 and light fixture, radiating effect is very poor, causes the overheated and combustibles such as the hair that gathers, dust that burn out or ignite of light fixture easily; And owing to have through hole 60 on the tube cover 10, when breaking out of fire, flare is leapt up out from through hole easily; Cause fire spreading, so this structure can not be prevented fires effectively.
BP 2462155 discloses a kind of LED light fixture, sees also Figure 12; It includes fire-resistant parts 113; This fire-resistant parts has above being and lets light source penetrate the sheet metal that removes hole, and led light source 115 is launched through this hole, and this structure realizes fire-proof function through resistant to elevated temperatures sheet metal fire-resistant parts is set; After LED lamp and wiring board are arranged on fire-resistant parts; Can effectively prevent to be burnt molten destruction, and LED lamp and wiring board contact with radiator 129, carry out efficiently radiates heat through radiator easily.But this structure only possesses fire-proof function, and does not possess incubation and thermal insulation function, but temperature is often very high in use for recessed light fixture, if reach combustibles such as hair or the foreign material of uniform temperature around igniting equally easily.Some countries are very high to the temperature requirement of recessed light fixture; Formulated relevant criterion; Indicate that the light fixture that reaches product standard without test not directly is installed on the flammable ceiling in surface, for some some country of Europe for example Britain, Denmark etc., to the requirement of smallpox light fixture and not merely only be the fire protecting performance aspect; But more be the security performance of light fixture, higher to the lamp surface temperature requirement.The structure of the fire-resistant parts that BP 2462155 is disclosed can not play the effect of insulation; Can not satisfy the requirement of lamp surface low temperature; There is high danger in combustibles such as hair around when lamp temperatures is too high, then igniting easily or foreign material and cause fire to take place.In addition, cooperating between the hole of said fire-resistant parts and the light source has the slit easily, can not reach good flameproof effect, and fire-resistant parts itself is also easily because of reasons such as bump, high temperature form the crack, and can not effectively prevent fires.
Therefore, but provide that a kind of fire protecting performance is stable, LED fire resistant lighting fitting that insulation simple in structure, surface temperature are lower, safe and reliable is real in necessary.
