Abstract: Disclosed is an intense pulse light device, in which plural divided light filters coated with individually different materials are rotatably and uniformly aligned around a reflection mirror in order to selectively filter lights according to wavelengths thereof, so that it is not necessary to exchange a handle body or filters, thereby improving convenience of use for the IPL device, and in which the loose contact of power lines and signal lines, leakage of cooling water, and penetration of impurities can be prevented, thereby improving reliability of IPL device. A semicircular reflection mirror aligned around a flash lamp installed in a body and a light filter section is aligned around the reflection mirror while forming a predetermined space therebetween. The light filter section is uniformly divided into two or four light filters so as to increase selectivity for the light radiated from flash lamp.

Abstract: A LED full-color lighting device contains a control unit, a light source unit, and a light display unit. The control unit relies on at least a potentiometer to apply various voltages to constant current sources, which in turn individually vary the current conducting through the red, green and blue LEDs of the light source unit, so as to deliver light of various colors. The colored light emitted from the light source unit can be easily and conveniently adjusted to fit a user's specific preference and mood. Colored patterns or textures can be formed on the light display unit so that the color of the light of the light source unit would mix with the colors of the patterns or textures to produce a visual effect as if some of the patterns or textures are changed.

Abstract: In one configuration, a gauge of an instrument cluster may have a base structure with an integrally molded dial structure and a separate, attached dial structure. A transparent area of the base structure may pass light from one side of the base structure to another side. This provides the ability to supply backlighting and floodlighting to the gage structure with just a single LED. The separate dial structure may be translucent to provide floodlighting or to supply light to graduations. Relative to a gauge pointer, inboard indicia in one dial structure denote vehicle speeds, while outboard graduations in another dial structure demark the indicia. The transparent portion of the base structure may be an integrally molded horizontal, angular or vertical portion within the base structure. Multiple levels and angles of the gauge provide a viewed component that is aesthetically pleasing and soothing to a viewer's eyes.
