  • Patent number: 9052418
    Abstract: A light source module optically coupled to an optical fiber which has a light incident surface is provided. The light source module includes a plurality of light sources and a concentrator. The light sources surround an axis, and the axis passes through a center of the light incident surface and is perpendicular to the light incident surface. Each of the light sources is capable of emitting a beam along a transmitting path toward the axis. The concentrator is disposed at the axis and includes a curvy reflective surface located on the transmitting paths for reflecting the beams to the light incident surface of the optical fiber.

  • Patent number: 8508138
    Abstract: A lighting system for dim ambience has at least one light source module, implemented in an ambience. The light source module has multiple light emitting units. Each unit is respectively controlled to produce a luminance. A luminance detecting unit detects a photonic luminance and a luminance ratio. A processing and operation module calculates a mesopic luminance according to the photonic luminance and the luminance ratio. When the photonic luminance is less than a dim-light setting value, a power control information is obtained by a fitness operation with a given condition set. The power control information is corresponding to an optimized mesopic luminance after fitness. A control unit receives the power control information to modulate the luminance of the light emitting units.
