Abstract: Improved method and apparatus for hand-held portable LED illumination. The illumination source includes a plurality of LEDs, and an electrical circuit that selectively applies power from the DC voltage source to the LED units, wherein the illumination source is suitable for handheld portable operation. In some embodiments, the electrical circuit further includes a control circuit for changing a proportion of light output having the first characteristic color spectrum output to that having the second characteristic color spectrum output, and that drives the LEDs with electrical pulses at a frequency high enough that light produced has an appearance to a human user of being continuous rather than pulsed. Still another aspect provides an illumination source including a housing including one or more LEDs; and a control circuit that selectively applies power from a source of electric power to the LEDs, thus controlling a light output color spectrum of the LEDs.

Abstract: A combination cap and shoe set is provided wherein each of the cap and shoe include illuminated regions. For example, the brim of the hat may be illuminated in its entirety in a particular color and the sole of the shoe may be illuminated in a complementary color such that a person wearing the cap and shoe of the invention in low light situations may be readily visible. The sole of the shoe may also be substantially uniformly illuminated and the illumination may be controlled independent of any walking motion by the wearer by a manual push-button switch.
Abstract: Due to an effect of a solenoid of a moving mechanism, when a valve and a shutter are positioned at a first position, a light source is positioned at a first light source position and a shutter is in a state of closing a window. A lighting luminous flux from a light source is reflected by a reflector so as to be irradiated as a first light distribution pattern. Thus, a part of the lighting luminous flux is introduced to the reflector from the open window. Therefore, it is possible to effectively utilize the lighting luminous flux emitted from one valve in correspondence to a light distribution pattern.
