摘要:
Disclosed is an illumination device comprising a radiation-emitting front side and a multiplicity of light sources (R, G, B), wherein said multiplicity of light sources (R, G, B) is divided into light source groups (LG) and the light source groups (LG) are arranged on the grid points of a first regular grid.
摘要:
A light-emitting diode array is disclosed which has two light-emitting diodes which are connected in antiparallel with one another, and a power supply which is suitable for energizing the light-emitting diodes independently of one another in the forward direction. In addition, an optical recording apparatus and a method for the pulsed operation of a light-emitting diode are disclosed.
摘要:
A light source element is employed back-lighting of liquid crystal displays and that comprises an obliquely placed light exit face and/or light entry face. At its surfaces, the light waveguide is surrounded by reflectors into which suitable aperture regions are potentially formed. A plurality of light sources and/or a more direct view is provided and, thus, a corresponding increase of the luminance results. A method is also provided for the manufacture of a light source element with an integrated reflector.
