Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT PAR 56 LUMINAIRE CONVERSION FROM SEALED BEAM UNIT TO TUNGSTEN HALOGEN LAMP WITH REFLECTOR IP Australia 0 Documents received on: 2 9 SEP 2000 0 Batch No: E The following statement is a full description of this invention, including the best method of performing it, known to me.
PAR 56 LUMINAIRE CONVERSION FROM SEALED BEAM LAMP ASSEMBLY TO TUNGSTEN HALOGEN LAMP ASSEMBLY WITH REFLECTOR This invention relates to improvements in the performance and lamp longevity in a PAR 56 lighting can. The PAR 56 lighting "can" is a staple of both theatre and music performance.
The original PAR 56 design uses a "sealed beam" type of lamp assembly, which incorporates the reflector and filaments in a sealed glass case. This type of lamp has particularly fragile filaments especially if handled whilst hot.
The sealed beam assembly is held in place in the Luminaire chassis by a spring clip, which expands against the inside of the chassis, against an integral rim.
This invention can be retro-fitted in the field, or lighting cans may be manufactured with the invention as original fitment.
The benefits are a "whiter" light due to the light spectrum of the Tungsten Halogen lamp, a wider angle of light distribution and a more even intensity of light, which is due to the combination of the length of the filament and shape and depth of the reflector. Also a side benefit is the greatly enhanced life span of the lamp due to the extra robustness of the filament of the Tungsten Halogen lamp.
The net result is a PAR 56, which works more efficiently and has a longer life.
Whilst there have been attempts to replace the sealed beam unit in favour of a more modern type of lamp before, such attempts seem mostly to have been made on the basis of economics; namely the lamp cost. My conversion unit does provide economic benefits, but as an added bonus to the improved functionality and longevity of the lamp due to the conversion.
METHOD
My invention replaces the sealed beam unit completely, with a custom-made aluminium dish-style reflector with a horizontally fitted Tungsten Halogen lamp mounted in a metal and ceramic mantle in the centre of the reflector.
The conversion unit is held in place by the same spring clip used to hold the sealed beam unit.
I designed the aluminium reflector to provide the most simple fitment of the conversion unit possible with the maximum improvement in light coverage.
The metal and ceramic lampholder is in a shape, with the arms protruding through holes cut or punched in the reflector. The "arms" hold and supply current to the lamp.
The lampholder is mounted to the rear of the reflector with a single screw through the centre of the reflector. Two wires run from the lampholder to a ceramic terminal block, which is mounted to the chassis of the Luminaire, providing the input point for power and the earthing point for the conversion unit and lamp.
Both the lampholder and the terminal block are similar to existing units not designed by me, but their usage in my design is mandated by the need to have the approval of the Chief Electrical Safety Inspector for C-Tick designation and both of these items are currently approved.
To assist with the understanding of the invention, reference is now made to the accompanying drawings, which show the invention.
Drawing 1 shows the Luminaire PAR 56 lighting can.
Drawing 2 shows the chassis and end-cap, with the conversion unit and retaining spring.
Drawing 3 is the abstract detailing the reflector, lampholder, lamp and terminal block.
Claims (1)
1. I have designed a conversion assembly to convert standard PAR 56 Luminaires/lanterns from the standard sealed beam unit to a Tungsten Halogen lamp, thereby providing a broader spread of lighting coverage and a more distinctive pattern of coverage, which is more effective with colored gels and also has a greatly increased lamp lifespan.
