Abstract (en)
[origin: EP0639874A2] A multi-array twin tube lamp assembly allows for increased luminous output in a compact volume. The lamp assembly comprises multiple twin tube lamps, each lamp having an electrode structure and independent discharge path. In one embodiment, the base may be modified to allow the multiple twin tube lamps to be assembled in closed proximity. Alternatively, the lampholders may be modified to allow the multiple twin tube lamps to be assembled in close proximity. The multi-array lamp arrangement may be operated at more than one discrete light level, with each lamp having its own separate voltage. Twin tube lamps may be connected electrically in parallel to essentially achieve extended lamp life. <IMAGE> <IMAGE>
