Abstract: A light system comprises at least three separate individual rigid metal LED heat sinks each having a respective substantially planar outwardly facing LED support surface and a flexible printed circuit board. The flexible printed circuit board comprises a flexible substrate carrying a plurality of LEDs, electrical control components, electrical input components and electrical traces. LED regions of the flexible printed circuit board carrying the LEDs are disposed on the outwardly facing LED support surfaces with light-emitting surfaces of the LEDs outwardly facing. Adjacent LED heat sinks are foldably coupled to one another by joints formed by fold regions of the flexible printed circuit board extending between respective spaced-apart edges of the adjacent ones of the LED heat sinks. Each adjacent pair of the outwardly facing LED support surfaces are non-parallel to one another whereby the outwardly facing LED support surfaces are disposed on notional faces of a notional polyhedron.

Abstract: The present disclosure describes light systems in which the intensity of base color LEDs configured to emit light within a target color region is increased using additional white LEDs and the emitted light is filtered so that a dominant portion of light passing through the filter at a particular viewing angle is within the target color region. The present disclosure also describes methods for forming a printed circuit board with an integral heat sink arrangement by depositing additional solder on solder pads that are not used to connect electronic components so that the additional solder acts as a heat sink.
