    Abstract: Multiple colors of light emitted by an assembled light emitting diode (LED) based illumination device is automatically tuned to within a predefined tolerance of multiple target color points by modifying portions of wavelength converting materials associated with each color. A first color of light emitted from the assembled LED based illumination device in response to a first current is measured and a second color of light emitted from the assembled LED based illumination device in response to a second current is measured. A material modification plan to modify wavelength converting materials is determined based at least in part on the measured colors of light and desired colors of light to be emitted. The wavelength converting materials may be selectively modified in accordance with the material modification plan so that the assembled LED based illumination device emits colors of light that are within a predetermined tolerance of target color points.

    Abstract translation: 通过修改与每种颜色相关联的波长转换材料的部分，由组装的基于发光二极管（LED）的照明装置发射的多种颜色的光被自动调谐到多个目标色点的预定义公差内。 测量响应于第一电流从组装的基于LED的照明装置发射的光的第一颜色，并且测量响应于第二电流从组装的基于LED的照明装置发射的第二颜色的光。 至少部分地基于所测量的光的颜色和要发射的光的所需颜色来确定修改波长转换材料的材料修改计划。 波长转换材料可以根据材料改性方案选择性地修改，使得组装的基于LED的照明装置发射在目标色点的预定公差内的光的颜色。

    Abstract: An optical characteristic measuring apparatus and an optical characteristic measuring method of the invention are an optical characteristic measuring apparatus and method for obtaining a predetermined optical characteristic such as a color value or a total spectral radiation factor of a measurement object. A spectral intensity distribution of predetermined ambient light entering through a measurement opening is measured and stored prior to measurement of the optical characteristic. In measuring the optical characteristic, an optical characteristic in a condition that actually measured ambient light is used as an observation light source is obtained, with use of the stored spectral intensity distribution of ambient light.

    Abstract: The illumination system has a plurality of light emitters (R, G, B) and a light­collimator (1) for collimating light emitted by the light emitters. Light propagation in the light-collimator is based on total internal reflection (TIR) towards a light-exit window (4) of the light-collimator. At least one light sensor (8) for optical feedback is placed outside the light-collimator and is arranged to receive light emitted by the light emitters exclusively through reflection at the light-exit window of the light-collimator. Preferably, the light sensor is placed substantially coplanar with the light emitters. Preferably, a side wall (35) of the light-collimator is provided with a protruding portion (9) for guiding the light reflected at the light-exit window of the light-collimator towards the light sensor. Preferably, the illumination system is provided with a reflector (12). Preferably, the illumination system comprises a holographic diffuser (17). Accurate sensing of the color mixing of light emitted by the illumination system is obtained.
