Title:
非結像光学的集中装置および照明システム
Document Type and Number:
Japanese Patent JP3682300
Kind Code:
B2
Abstract:
A nonimaging concentrator (or illuminator) of light. The concentrator (or illuminator) has a shape defined by dR/d phi =Rtan alpha where R is a radius vetor from an origin to a point of reflection of a light edge ray from a reflector surface and phi is an angle between the R vector and an exit aperture external point of the concentrator (illuminator) and coordinates (R, phi ) represent a point on a reflector curve and alpha is an angle the light edge ray from an origin point makes with a normal to the reflector curve. The reflector surface allows the light edge ray on the reflector curve to vary as a function of position. In the concentrator an absorber has a shape variable which varies with position along the absorber surface.
