Field of the Invention This invention relates to a luminaire, and more particularly to a luminaire suitable for mounting on a luminaire attachment such as a ceiling, wherein the luminaire is provided with a fire protection unit for delaying the spread of fire at the occurrence of an accidental fire caused by the luminaire.

Background technique

Ceiling light fixtures are a common lighting fixture in everyday life that can be mounted on the ceiling for indoor lighting. According to the adjustable and non-adjustable illumination direction of the light emitted by the ceiling lamp, the ceiling lamp can generally be divided into an illumination angle adjustable ceiling lamp and a lighting angle fixed ceiling lamp. Ceiling luminaires with fixed angles of illumination are fixed because of the angle of illumination once installed. This is inconvenient when the user has the need to adjust the angle of illumination. The existing illumination angle adjustable ceiling lamp can realize multi-angle illumination to the indoor. When the user adjusts the illumination angle, the user can automatically adjust the illumination angle manually or through preset parameters to realize multi-angle illumination. .

The existing illumination angle adjustable ceiling luminaire generally comprises a illuminating element for providing a lighting source; an adjusting element for the user to adjust the illuminating angle of the luminaire; a fixing unit for mounting the luminaire on the ceiling For illumination; a connector to connect the fixed unit and the adjustment element together and a heat dissipating element to prevent excessive accumulation of heat generated during operation of the illuminating element and to lower the ambient temperature of the illuminating element. The components of such a luminaire are generally made of materials such as plastic, aluminum metal or aluminum alloy, which are light in weight, beautiful in appearance and rust-free. However, the ceiling light fixture also has many shortcomings. First of all, for aesthetics, ceiling lamps are generally embedded in the ceiling, so the fixture will destroy the overall fire performance of the fireproof ceiling. When the materials constituting the luminaire are made of a material such as plastic, aluminum metal or aluminum alloy which can withstand a temperature of only 600 degrees Celsius, in the event of a fire and the temperature exceeds 600 degrees, the components constituting the luminaire are It will be melted, and the flame will spread from the ceiling below the ceiling to the ceiling, or from the ceiling to the bottom of the ceiling, causing the fire to spread quickly and cause serious damage. Secondly, the illumination angle can be adjusted to adjust the illumination angle of the ceiling lamp. It is often necessary to leave a certain space between the angle adjustment component of the lamp and the fixing component of the lamp, so that the fire that occurs during the fire will easily spread through these spaces. To the top of the ceiling, the fire spreads and expands rapidly in a short period of time, causing heavy damage before the disaster relief and firefighting personnel have arrived. Great loss. Again, when the components of the luminaire are burned, the components of the fused lamp will fall from the ceiling, thereby threatening the safety of the indoor personnel. In addition, after the components of the luminaire that have been burnt at a high temperature fall from the ceiling, the flammable objects in the room are ignited and the fire is quickly spread to the room.
