A flexible graphite sheet support structure forms a thermal management arrangement for device having a heat source. The flexible graphite sheet support structure includes first and second spaced apart support members and a flexible graphite sheet secured to the spaced apart support members forming a free standing flex accommodating section that spans between them. Curve retention members having convex curved surfaces are used to keep the flex accommodating section in a bell shaped curve while preventing the flexible graphite sheet from exceeding a minimum bend radius. The thermal management arrangement formed by the flexible graphite sheet support structure enables the flexible graphite sheet to move heat from one support structure to the other while reducing the transmission of vibration between them and allowing relative movement between the spaced apart support structures.

Flexible graphite sheet support structure and thermal management arrangement

A light source () includes a light emitting semiconductor device (). A support substrate () has a generally planar reflective surface () that supports the semiconductor device (). The light emitting semiconductor device heat sinks via the support substrate. A curved reflector () has a concave parabolic reflective surface. The light emitting semiconductor device () is arranged between the support substrate () and the curved reflector (). The support substrate () and the curved reflector () together define a light aperture () through which light produced by the light emitting semiconductor device () passes.

A showerhead ( ) or faucet ( ) includes a water outlet ( ) for emitting a water flow ( ) and a handle ( ) for controlling the water flow ( ). At least one LED ( ) is arranged on or in the showerhead ( ) or faucet ( ) and viewable by an associated user thereof. A light-transmissive encapsulant ( ) seals the at least one LED ( ) and transmits light produced by the at least one LED ( ) to the associated user. A controller ( ) produces a controller output for controlling the LED light emission responsive to at least one of a water flow rate, a water flow temperature, an ambient light level, and a position of the handle ( ). The at least one LED ( ) is can be arranged on a printed circuit board ( ) and electrically powered via conductive traces thereon, in which case the light-transmissive encapsulant ( ) seals the LED source and the conductive traces.
