20120184067 | Releasing and post-releasing processes in fabrications for micromirror array devices - A releasing and post-releasing method for making a micromirror device and a micromirror array device are disclosed herein. The releasing method removes the sacrificial materials in the micromirror and micromirror array so as to enabling movements of the movable elements in the micromirror and micromirror array device. The post-releasing method is applied to improve the performance and quality of the released micromirrors and micromirror array devices. | 07-19-2012 |
20120235600 | METHOD OF OPTIMIZING LIGHT OUTPUT DURING LIGHT REPLICATION - A method of utilizing a light replication luminaire to match the spectral characteristics of light that is output from the luminaire to the spectral characteristics of a target light spectrum is provided. In one example, the method permits the user to assign a weight to one or more characteristics of the target light spectrum to be replicated. A best approximation of the target light spectrum is then determined, taking into account the weight assigned to each characteristic. In another example, the target light spectrum is provided to the luminaire by the user through the specification of various characteristics of the target light spectrum. | 09-20-2012 |
20130307419 | LIGHTING SYSTEM WITH SENSOR FEEDBACK - A lighting system includes multiple light sources, a sensing unit, and a control system. The light sources have different emission spectra, and the sensing unit is configured to measure a spectral content of light. The control system may be configured to use measurements from the sensing unit to select respective intensities for emissions from the light sources and then independently control the light sources to emit the respective intensities. In particular, the control system can select and render a spectral distribution selected based on the light reflected from objects that are being illuminated or render a spectral distribution to supplement light from other light sources and achieve a lighting objective. | 11-21-2013 |
20130313444 | METHOD AND APPARATUS FOR TESTING LUMINESCENT FILMS - A structure for testing a luminescent film includes a Lambertian light source, an integrating sphere having an input port, and a measuring device. The Lambertian light source includes a mixing chamber having an input port and an output port, and a light emitter coupled to the input port. During testing the luminescent film is positioned between the output port of the mixing chamber and the input port of the integrating sphere. The measuring device is optically coupled to the integrating sphere. | 11-28-2013 |
