摘要:
A structured lighting material, an illuminator, and the method to generate incoherent luminescence wherein luminescent intensity increases superlinearly when excitation energy applied thereto through electron beam, electric charge, electric field or the like exceeds a threshold. In the present invention, the structured lighting material is easily made to have a minute uneven surface. This invention enables high-efficient lighting devices, sensors and memories owing to the superlinearity.

摘要:
A light source device using an optical fiber in which the light emitted from a filament lamp is incident on the end face of the optical fiber with high efficiency is achieved by using a reflector which is an ellipsoid of revolution having first and second focal points, the filament coil of the lamp being located at the first focal point and the end face of the optical fiber being located at a second focal point. Furthermore, the area of the filament of the filament lamp A (mm2), an area of the incidence face of the optical fiber B (mm2), and a value of a focal length C, set as a distance between an apex of the reflector and the first focal point divided by a distance between the apex of the reflector and the second focal point, have a relationship with respect to each other such that a constant a defined by the relationship: &agr;=A×(C/B) has a value that is less than or equal to 20.
