A color display device () includes a backlight () that cyclically emits first, second, and third component color backlighting in turn over a cycle period. The cycle period repeats at a cycling frequency (f) that exceeds a maximum human visual response frequency. A liquid crystal display (LCD) () generates a first display during the first component color backlighting, a second display during the second component color backlighting, and a third display during the third component color backlighting.

Liquid crystal display with color backlighting employing light emitting diodes

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.

A light module includes a light emitting diode assembly defining a front side light emitting diode array and a rear side. The rear side is in thermal communication with a thermally conductive spreader, and a thermally conductive core is in thermal communication with the conductive spreader. The thermally conductive core includes an electrical conductor in operative communication with the front side light emitting diode array, and a plurality of appendages disposed about the thermally conductive core such that they are in thermal communication with the conductive spreader.

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 ( ).

LED-based modular lamp

A flashlight includes a housing, an electrical power source in the housing, a semiconductor light source, a reflector well in which the semiconductor light source is seated, and a lens over the reflector. The housing has a closed end and an open end. The semiconductor light source is electrically connected to the power source. The semiconductor light source, reflector, and lens are secured to the housing. Light produced by the semiconductor light source is reflected by the reflector and focussed by the lens in a predetermined direction.
