Abstract:
A method of removing a stain from a target object and an apparatus therefor are provided. The method comprises the steps of: placing a light source at a preset distance from the stain; illuminating the stain with light having a wavelength in the range of [400nm, 500nm] generated by the light source, wherein the light generated has a preset light intensity at the surface of the stain. With the illumination of the light source having a wavelength in the range of[400nm, 500nm], some stains, i.e. stains caused by food, can be removed from some target objects, i.e. fabrics.

Abstract:
The disclosed embodiments relate to functional and decorative lighting. A transparent body(100) comprises a plurality of light guides (130, 140) forming a matrix. Light is emitted fromlight sources (210, 220). In the cells of the matrix in which light from different light sources (210, 220) intersects, the light is mixed which results in different cells having different colors.
Abstract:
The invention relates to an electroluminescent device for emitting light having an adjustable color point. An electroluminescent region (1) emits light in response to a lighting current and a heating element (7) applies heat to the electroluminescent region (1). A heating control unit (9) controls the heating element (7) in applying the heat in order to adjust the color point of the emitted light. The color point of the light emitted by the electroluminescent device is dependent on the temperature of the electroluminescent region (1). Since the electroluminescent device comprises a heating element (7) for applying heat to the electroluminescent region (1) and a heating control unit (9) for controlling the heating element (7) in applying the heat, the color point can be adjusted in a simple way by using the heating control unit (9).
Abstract:
When constructing a nuclear detector module in a gantry, a plurality of overlapping light guide modules (10) are mounted to the gantry in a spaced-apart fashion, and a plurality of underlapping light guide modules (12) are mounted in between each pair of overlapping light guide modules (10). Each of the underlapping modules and the overlapping modules includes a scintillation crystal array (16) on an interior surface thereof, and a plurality of PMTs on an exterior surface thereof. Overlapping modules (10) have overlapping structures (22) that interface with underlapping structures (18) on the underlapping modules (12) and thereby eliminate a seam directly beneath PMTs that overlap the crystal arrays of both an overlapping module and an underlapping module. Optical grease is used to form a resilient grease coupling and reduce light scatter between the underlapping and overlapping modules.
