20150308637 | ILLUMINATION SYSTEM AND WAVELENGTH-CONVERTING DEVICE THEREOF - An illumination system includes a solid-state light-emitting element and a wavelength-converting device. A first waveband light is emitted to an optical path by the solid-state light-emitting element. The wavelength-converting device is disposed on the optical path and includes a phosphor plate. The phosphor plate is a solid mixture having a phosphor agent and a binder. The weight percent of the phosphor agent is from 10 to 70, such that the first waveband light is transformed into a second waveband light. Under this circumstance, the efficiency of heat conduction of the phosphor plate is effectively enhanced, thereby enhancing the converting efficiency of the wavelength-converting device, which is strong enough to be applied to rotate with great rigidity. Meanwhile, not only the space requirement is reduced, but also the phenomena of hot spot and heat diffusion are avoided, such that the cost and difficulty of manufacturing the wavelength-converting device are significantly reduced. | 10-29-2015 |
20160069535 | WAVELENGTH-CONVERTING DEVICE AND ILLUMINATION SYSTEM USING SAME - A wavelength-converting device includes a first substrate, a second substrate and a first wavelength-converting material. The first substrate has a first region and a first engagement portion. The second substrate is disposed adjacent to the first substrate and having a second region and a second engagement portion. The second engagement portion and the first engagement portion have complementary shapes. The first wavelength-converting material is disposed on the second region for converting a light in a first waveband into a light in a second waveband. The light in the first waveband is transmitted through the first region, and the light in the second waveband is reflected by the second region. The first region and the second region are staggered, so that the first engagement portion and the second engagement portion are engaged and fixed with each other. As a result, the safety and stability are enhanced, and the noise is reduced. | 03-10-2016 |
20160069538 | WAVELENGTH-CONVERTING DEVICE AND ILLUMINATION SYSTEM USING SAME - A wavelength-converting device used for converting first waveband light includes a transmissive substrate, a phosphor layer and an optical layer. The transmissive substrate has a refraction coefficient n | 03-10-2016 |
20160086573 | REAL-TIME COLOR MAPPING SYSTEM AND METHOD - A real-time color mapping system includes a memory and a converting module. The memory is configured for storing a mapping table. The converting module is configured for reading the mapping table stored in the memory, and for converting first image grayscale values corresponding to a first image signal into second image grayscale values corresponding to a second image signal according to the mapping table. The converting module utilizes at least part of bits corresponding to each of the first image grayscale values as a memory address to look up in the mapping table, thereby converting the first image grayscale values into the second image grayscale values. A real-time color mapping method is provided herein as well. | 03-24-2016 |
20160102820 | OPTICAL WAVELENGTH-CONVERTING DEVICE AND ILLUMINATION SYSTEM USING SAME - An optical wavelength-converting device used for converting a first waveband light includes a substrate, a phosphor layer and a composite reflection layer. The phosphor layer is disposed on the substrate for converting the first waveband light into a second waveband light. The composite reflection layer includes a first reflection layer and a second reflection layer. The first reflection layer is disposed between the substrate and the phosphor layer and adjacent to the substrate for reflecting the second waveband light, such that the second waveband light is transmitted through the phosphor layer so as to be outputted. The second reflection layer is disposed between the first reflection layer and the phosphor layer for adjusting the reflection spectrum of the first reflection layer, thereby enhancing the reflection rate of the composite reflection layer. As a result, the output efficiency of the wide-angle and wide-spectrum light is increased. | 04-14-2016 |
20160116122 | PHOSPHOR DEVICE AND MANUFACTURING METHOD THEREOF - A phosphor device of an illumination system, which emits a first waveband light, includes a substrate and a first phosphor layer. The first phosphor layer includes a first phosphor agent and a second phosphor agent. The first phosphor agent is formed on the substrate for converting the first waveband light into a second waveband light. The second waveband light comprises a first color light and a second color light. The second phosphor agent is distributed over the first phosphor agent for converting the first waveband light into the second color light so as to increase the luminous intensity of the second color light. Therefore, the luminous intensity of the second color light can be effectively increased. | 04-28-2016 |
