Abstract:
1. A CCFL device, comprising: at least two adjacent and overlapping layers of CCFLs, each layer comprising at least one CCFL, for a total of at least two CCFLs said at least two CCFLs emitting light of different color temperatures, each of said at least two CCFLs comprising elongated segments connected at their ends to form a serpentine shape, said segments in each of said at least two CCFLs being substantially parallel to one another, the segments in said at least two CCFLs being transverse to one another; a driver converting an input power to AC power of higher voltage suitable for CCFL operation, and supplying the higher voltage AC power to the at least two CCFLs to cause it to generate light; at least one fixture supporting the at least two CCFLs and the driver, said at least one fixture including a supporting plate and means for attaching to the supporting plate the at least two CCFLs at a plurality of locations along their lengths; a connector having a configuration adapted to be electrically and mechanically connected to a conventional electrical socket to support and power the device, said at least one fixture mechanically connecting said at least two CCFLs, the driver and the connector to form a unitary mechanical structure; a housing defining a chamber therein that houses said at least two CCFLs; and a driver housing defining a chamber therein that houses said driver, wherein said driver housing and said housing that houses said at least two CCFLs are spaced apart by an air gap external to the device.
