Abstract: A luminous glazing is provided that includes a pane and a light guide. The pane has two opposite faces and is transparent in the visible spectrum. The light guide has a core surrounded by a cladding so that the core is capable of guiding light along the longitudinal extension of the light guide. The light guide includes a light scattering element so that when light is injected into one of the end faces if the light guide, the light guide is a side-emitting light guide and forms a linear light source. The light guide extends along the faces and is disposed on one face such that the light scattering area is spaced apart from the face and so that light guided in the core, scattered, and laterally exiting from the light guide enters the transparent pane through the face and is be transmitted through the pane to the opposite face.

Abstract: An LED lighting device for connection to an AC voltage source is provided. The lighting device includes at least a first and a second set of LEDs, at least two LEDs assigned to the first set of LEDs and electrically arranged in series, and at least two LEDs assigned to the second set of LEDs and electrically arranged in series, a connector configured to connect the LED lighting device to the AC voltage source, and a set activator. The set activator having a voltmeter for measuring a currently applied voltage amplitude of the AC voltage source, a signal generator for generating a switching signal in response to the currently applied voltage amplitude, and a current controller for controlling the current flowing through the at least first and second sets of LEDs.

Abstract: 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.

Abstract: An illumination device for generating white light is provided. The device includes a converter and a filter. The converter has a Ce:YAG ceramic, which converts blue excitation light into yellow light of a color location near the white point in the chromaticity diagram. The filter attenuates a light fraction below 530 nm so as to obtain the white light.
