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.

LED planar light source and low-profile headlight constructed therewith

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.

Night light for plumbing fixtures

A lamp ( ) includes an optics module ( ) and an electronics module ( ). The optics module ( ) includes a plurality of LEDs ( ) arranged on a printed circuit board ( ) and having a plurality of input leads, and a heat sink ( ) having a conduit ( ) for the input leads. The plurality of LEDs ( ) thermally communicate with the heat sink ( ). The electronics module ( ) is adapted to power the plurality of LEDs ( ) through the input leads. The electronics module ( ) has a first end ( ) adapted to rigidly connect with the heat sink ( ), and a selected electrical connector ( ) arranged on a second end for receiving electrical power. The electronics module ( ) further houses circuitry ( ) arranged therewithin for adapting the received electrical power ( ) to drive the LEDs ( ).
