Abstract

A fire rated LED down light comprises a steel can 1 to which is secured a spring holder 2. Springs 4 secure the unit in an aperture in a ceiling. A LED driver 5 is secured to the back of an aluminium bezel unit 31 that also acts as a reflector 32 and heat sink. The bezel/LED unit 5, 31 is secured to the steel can 1 by clips 34.

Description

Description:
Fire rated LED down-light that dissipates the excess heat via a front bezel trim heat-sink.
[a] Background to the Invention
Previously the conventional way to construct a fire rated LED down-lighter was to place a heat-sink on top of the LED circuit board within the main body of the Luminaire. Controlling the LED from an external Driver [electronic control gear]
[b] Detailed Description of Invention
[a] An LED self contained Down lighter with a fire rated construction, integral driver [electronic control gear] and reflector housing trim bezel heat sink/ dissipater.
[c] Examples:
An example of the invention will now be described by referring to the accompanying drawing Fig. 1 Figure 1 illustrates a typical arrangement of the current invention. Figure 1, shows a fire rated LED recessed downlight, it consists of [1] a steal can with enclosed back [11], a small wiring cable entry hole [13], extended circular flanged edge at the front opening [12] and a steal ring[ 14] welded to internal wall of the steal can. Steel spring holder [2] that is attached to the top of the steel can [1]; a pair of spring clips that are attached to the side of the spring holder; an cylindrical aluminium inverted dish in the shape of a brimmed hat. The aluminium unit further consists of, back plate [33] where led/led pcb is attached to, wall [32], which may also be shaped to function as reflector, front decorative ring that also functions as the heat sink, elastic clips [14] that holds the aluminium unit[ 3] to the steel can [1]. An LED driver [ 4] that is attached to the back of the aluminium unit with electrical cable[ 41] that connects to external mains power source.
The outer body canister sometimes referred as a fire can is made from materials that can sustain a high temperature [over l000degrees], usually steel. The spring holder is fixed to the outer canister, [2], on both sides of the spring holder there are two apertures, as shown in the diagram, allowing the spring clips to be attached to. As shown in Figure 1, the fire can is inserted to an opening in the ceiling, where the diameter of the opening is smaller than the maximum outer diameter of the flanged lower edge. The spring clips lifts the fire can upwards, locating the fire can in the ceiling. Once the fire can is in position, it covers the opening in the ceiling completely, forming a fire resistant layer.
The aluminium unit including a large decorative ring at the front opening serve the main purpose of heat dissipation. The LED is attached to the aluminium can, the heat conducts through the wall, reaches the front ring where heat exchange with surrounding air takes place. The LED driver[ 4] is fixed to the back of the aluminium can. The electric input cable of the driver goes through the wiring hole [13] connecting to external power supply. The input electrical cable is wired to the driver through internal terminals in the driver box.
The Aluminium can [3] with the LED chip [5] and LED driver[ 4] forms a LED lighting module that can be attached/detached tolfrom the fire can. When attaching the said lighting module, it is pushed into the fire can [1]. The clips are first pushed towards the centre of the lighting module by the steel ring[ 14], and then extend outwards to hold on to the steal ring once the lighting module is fully inserted into position. The lighting module can be detached from the fire can[ 1] by pulling it out. During the movement the elastic clips are again pushed inwards by the steel ring, allowing the LED lighting module to be fully detached from the fire can.

Claims (18)

  1. Claims: 1. A fire rated recessed down light that consists of a fire resistant can with means of securing itself to an aperture of a fire rated ceiling, maintaining the fire resistant rating of the ceiling; a heat conductive unit with front rim/bezel that sits on the surface of the ceiling, when inserted into the fire resistant body canister. The heat conductive aluminium unit has a means of securing itself to the inside of the fire resistant canister. Light source of the down light is located in the inside of the heat conductive unit. Heat generated by the light source conducts through the heat conductive unit and dissipates to the open air via the rim of the heat conductive unit.
