Definitions
- the present invention relates to lighting apparatus, and in particular luminaires and illuminated signs.
- High frequency controllers are reliable and have substantial meantime between failures. However, like all electronic equipment, although the average meantime between failures may be long, failures do occur. A small percentage of failures occur early in the life of the lighting fixture. The cost of replacement of the high frequency controller and removal and re-insertion of all the wires involved is high.
- This invention seeks to improve the utilisation of space by producing a more efficient method of wiring and to reduce the cost of lighting maintenance.
- the present invention provides lighting apparatus for receiving a lamp, comprising power input means for connection to a power supply, control means for controlling the current fed to said lamp, and at least one busbar comprising printed wiring, the at least one bus bar being connected to the output of the control means and connectable to said lamp to feed power thereto via the printed wiring.
- the at least one bus bar is selectively detachable from the apparatus .
- bus bars can be clicked immediately into place and may reduce manufacturing assembly times by a factor of 4 to 10.
- this invention enables replacement of all conventional wiring for connecting fluorescent lamps to control equipment, i.e. conventional switch start circuirty (choke, starter and power factor correction capacitor) or a high frequency electronic ballast, to be replaced by bus bars that can be manufactured as component sub-assemblies.
- a portion of the surface of the at least one bus bar is covered by a light reflective material.
- the at least one bus bar may be in the form of a printed circuit formed on either flexible or rigid material. Also the at least one bus bar may provide connections for the transfer of data and/or control signals between difference components of the apparatus. In addition, the apparatus may include emergency lighting circuitry, the at least one bus bar providing connections to feed power and/or control signals thereto.
- Figure 1 shows a multiple fluorescent lamp luminaire or sign in accordance with the invention, using a high frequency ballast control unit
- Figure 2 shows a multiple fluorescent lamp luminaire or sign using an inductor starter and a power factor correction capacitor
- Figure 3 shows a bus bar system with possible options for controls, sensors and monitoring systems
- Figure 4 shows a bus bar system for large sign or luminaire systems using flexible printed circuit connections .
- this shows a luminaire configuration for four fluorescent lamps 111 operating from an electronic high frequency controller 16.
- the mains supply input is directly wired into a three way terminal block 18 mounted on the high frequency controller 16, and protected by a fuse 19.
- the lamp connectors 12 are directly connected to the bus bar 11.
- Bus bars 11 as illustrated have a range of options to configure this luminaire as a four, three, two or one lamp 120 luminaire by using other fixing positions 110 for lamp connectors 12.
- This shows a typical lamp configuration for 600 mm x 600 mm luminaires that may vary from 4 lamp units down to 2 lamp units, however there is no limit on the number of possible lamps 11 that may be connected on a bus bar 11 system. A large number of lamps may well be required in a large illuminated sign.
- Two bus bar units 11 are used in the illustrated luminaire to provide connections to fluorescent lamps 111, one on the left and the other on the right, lamps 111 being plugged into the lamp connectors 12 between the two bus bars 11.
- a single bus bar unit only may be required to connection to lamps having both terminals at one end thereof .
- An interconnecting printed circuit board 15 is connected through plug 13 on each of the bus bar units 11 which plugs into sockets 14 mounted at each end of the interconnecting printed circuit board 15. This connects all the necessary lamp connections to the high frequency controller 16 through connector plugs 17.
- the high frequency controller 16 only needs to be plugged into the interconnecting printed circuit board to be installed into the luminaire or sign, during manufacture or installation. In the manufacture of a luminaire all the necessary connections and lamp connectors are manufactured as bus bar 11 and interconnecting printed circuit board 15 sub- assemblies, with the high frequency controller 16 as a separate unit that plugs into the interconnecting printed circuit board 15.
- the sub-assemblies including the bus bar units 11, may be fitted into the luminaire as a kit of parts at the point of installing the luminaire or sign unit.
- FIG. 2 shows bus bar techniques adopted in a conventional switch start luminaire or sign using chokes, starters and power factor capacitors.
- the choke 121, starters 122 and capacitor 123 are assembled onto the interconnecting printed circuit board 15 and connected to bus bars 11 via connectors 14 and 13.
- Controls, sensors and monitoring devices may be integrated into the bus bar system as shown in Figure 3.
- passive infrared control 124, photo cell control 125, variable energy control 126, air quality sensors 127, lamp light level monitor 128, smoke detector 129, heat detector 130, infrared receivers and transmitters 131 and radio telemetry systems 134 may be selectively incorporated .
- FIG. 4 shows the use of flexible printed circuit connections 135 between the bus bars 11, and the control unit 15 which may be appropriate in large luminaires or signs. Also, an additional flexible printed circuit connection 136 may be connected where required to the bus bar 11 by connectors 137. Emergency lighting control systems could also be integrated into the bus bar design concept where needed in luminaires .
