20110259419 | SOLAR CELL WITH AN IMPROVED PIGMENTED DIELECTRIC REFLECTOR - The solar cell has a pigmented dielectric reflector, which includes two dielectric layers with different refractive indices and pigments embedded in the layers, so that the solar cell has good light-trapping properties and high efficiency with a small reflector layer thickness. The material systems suitable for producing the pigmented dielectric reflector are also part of the invention. | 10-27-2011 |
20150062953 | LIGHTING EQUIPMENT FOR GENERATING LIGHT OF HIGH LUMINANCE - Lighting equipment for generating white light from blue or violet excitation light and converted emitted yellow light is provided. The excitation light is directed at an oblique angle towards a converter that is attached to a carrier device, without the emitted illumination light impinging on the carrier device. | 03-05-2015 |
20150070907 | OPTICAL CONVERTER FOR HIGH LUMINANCES - An optical converter for producing colored or white light from blue excitation light is provided. The converter has good scattering properties to be able to produce nearly white light from the scattered blue light components and the scattered, converted yellow light components. The optical converter includes material including one or more of a YAG ceramic, a LuAG ceramic, and a magnesium-aluminum ceramic exhibiting strong scattering. | 03-12-2015 |
20150077973 | WHITE LIGHT ILLUMINATION DEVICE - A converter ( | 03-19-2015 |
20150092392 | GENERATION OF WHITE LIGHT - An arrangement for generating white light is provided. The arrangement generates the white light by combining blue light and yellow light. The yellow light originates from a converter which transforms into yellow light virtually all blue light that enters the converter. | 04-02-2015 |
20150241046 | COOLING OF A CONVERTER ARRANGEMENT FOR LIGHT SOURCES WITH HIGH LUMINANCE - A converter arrangement for light sources with high luminance is provided that includes an axially pivotable carrying wheel and a converter fixed on one side of the carrying wheel. The converter includes fluorescent materials that convert impinging light into light having a different wave length and emits the light having the different wavelength. The ratio of the total area of the converter arrangement to the area enclosed by the outer boundary curve of the converter is at least 3, preferably at least 3.5, particularly preferably at least 4.5. | 08-27-2015 |
20150292699 | FIBER-OPTIC CONVERSION MODULE - A fiber-optic conversion module is provided as part of a lighting device on a vehicle. The module includes optical fibers with connectors, a light exit head, and a converter mounted on a cooling element. Shorter wavelength excitation light is fed to the optical fibers that emit the excitation light towards the converter arranged at an angle relative to the beam direction, at a light spot that remits useful light in a radiation angle in form of a cone of useful light and reflects excitation light as a Fresnel reflection substantially outside the cone of useful light, where Fresnel reflection is made harmless by a light stop. | 10-15-2015 |
20150298424 | LAYER COMPOSITE, METHOD FOR THE PRODUCTION THEREOF AS WELL AS USES THEREOF - A layer composite is provided that includes optoceramic layers. Additionally, a method for the production of the layer composite, as well as uses thereof are also provided. The layer composite is suitable as a converter material such as a converter material for LEDs. With the use of the layer composite, white LEDs can be produced which also in the passive state, i.e. when the light source is switched off, result in a white color impression. | 10-22-2015 |
