Abstract
A recessed light apparatus for being installed at a ceiling includes a light source unit, a heat sink for dissipating heat generated from the light source unit, and a thermal insulating member coupled between the heat sink and the light source unit to define an upper space above the heat insulating member and a bottom space below the thermal insulating member. In case of fire, the heat insulating member prevents flame or fire spreading from the bottom space to the upper space.
Claims20
A recessed light apparatus for installing into a ceiling, comprising:
- a light source unit for generating light;
- a heat sink supported above said light source for dissipating heat from said light source unit;
- a thermal insulating member provided below said heat sink defining a light chamber therein and having a first through channel, wherein a peripheral portion of said thermal insulating member is outwardly extended for coupling at the ceiling, such that said thermal insulating member forms an insulation partition for preventing fire spreading above said thermal insulating member in case of fire;
- and
- a light adjustor disposed in said light chamber, wherein said light adjustor has a light entrance aligned with said first through channel and a light exit aligned with said light entrance for allowing the light to pass through said light entrance to said light exit.
A thermal insulating arrangement of a ceiling light having a light source unit and a heat sink having a heat conducting channel to dissipate heat from the light source unit, comprising:
- a thermal insulating member provided below said heat sink, wherein a peripheral portion of said thermal insulating member is outwardly extended for coupling at the ceiling, such that said thermal insulating member forms an insulation partition for preventing fire spreading above said thermal insulating member in case of fire.
