Abstract: A lamp (10) includes an optics module (12) and an electronics module (14, 60, 70). The optics module (10) includes a plurality of LEDs (76) arranged on a printed circuit board (18) and having a plurality of input leads, and a heat sink (22) having a conduit (40) for the input leads. The plurality of LEDs (16) thermally communicate with the heat sink (22). The electronics module (14, 60, 70) is adapted to power the plurality of LEDs (16) through the input leads. The electronics module (14, 60, 70) has a first end (52) adapted to rigidly connect with the heat sink (22), and a selected electrical connector (50, 62, 72) arranged on a second end for receiving electrical power. The electronics module (14, 60, 70) further houses circuitry (80) arranged therewithin for adapting the received electrical power (82) to drive the LEDs (16).

Abstract: A showerhead (802, 804) or faucet (12, 602, 702) includes a water outlet (16, 606, 706, 802) for emitting a water flow (22, 610, 710) and a handle (18, 20, 604, 704, 830) for controlling the water flow (22, 610, 770). At least one LED (42, 242, 342, 442, 542, 544, 546, 624, 658, 730, 810) is arranged on or in the showerhead (802, 804) or faucet (12, 602, 702) and viewable by an associated user thereof. A light-transmissive encapsulant (630, 660, 732) seals the at least one LED (42, 242, 342, 442, 542, 544, 546, 624, 658, 730, 810) and transmits light produced by the at least one LED (42, 242, 342, 442, 542, 544, 546, 624, 658, 730, 810) to the associated user. A controller (550) 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 (18, 20, 604, 704, 830).
