    摘要： A system to provide radiant energy of selectable spectral characteristic (e.g. a selectable color combination) uses an integrating cavity to combine energy of different wavelengths from different sources. The cavity has a diffusely reflective interior surface and an aperture for allowing emission of combined radiant energy. Sources of radiant energy of different wavelengths, typically different-color LEDs, supply radiant energy into the interior of the integrating cavity. In the examples, the points of entry of the energy into the cavity typically are located so that they are not directly visible through the aperture. The cavity effectively integrates the energy of different wavelengths, so that the combined radiant energy emitted through the aperture includes the radiant energy of the various wavelengths. The apparatus also includes a control circuit coupled to the sources for establishing output intensity of radiant energy of each of the sources. Control of the intensity of emission of the sources sets the amount of each wavelength of energy in the combined output and thus determines a spectral characteristic of the radiant energy output through the aperture.

    摘要： Apparatus is disclosed that efficiently projects electromagnetic radiation over a predetermined spherical sector with a tailored intensity distribution. The apparatus includes a base having a cavity and aperture that faces the spherical sector to be illuminated, with a flat, ring-shaped shoulder surrounding the aperture. The apparatus further includes a mask spaced over the aperture and a baffle projecting from the mask toward the aperture. The base, the mask, and the baffle are formed of a material having an outer surface with a significant diffuse, reflective characteristic. A source emits electromagnetic radiation (e.g., visible light) into the base cavity, and the base, mask and baffle are configured to redirect this radiation outwardly with the tailored intensity distribution (e.g., a uniform distribution) over the predetermined spherical sector (e.g., a hemisphere, or 2 .pi.steradians).

    摘要： A quadrant light detector that employs the concept of constructed occlusion to improve its accuracy and by incorporating baffles within the design to improve its detection response to incoming light having an incidence angle neat the horizon, and to divide a diffusely reflective cavity into quadrants. The quadrant detector is able to determine the direction, or azimuth and elevation, to the light source anywhere within a sector of a hemisphere or a sphere.
