Strahlungserzeugungsvorrichtung zum Erzeugen einer elektromagnetischen Strahlung mit einer einstellbaren spektralen Zusammensetzung und Verfahren zur Herstellung derselben

DE 102009046831 A1 UPAB: 20110605 NOVELTY - The device has thermal radiation elements (1, 1n) e.g. organic LEDs or inorganic LEDs, generating radiation element-specific electromagnetic radiations (4n). A dispersive optical element (2) e.g. diffraction grating, deflects the radiation element-specific electromagnetic radiations based on wavelength and a position of the radiation elements. A determined spectral range is provided through an optical opening (3) by the radiations, so that spectral composition of electromagnetic radiation (220) resulted by the opening is adjusted by selective activation of the radiation elements. DETAILED DESCRIPTION - The dispersive optical element is designed as a concave diffraction grating or prism. An INDEPENDENT CLAIM is also included for a method for manufacturing a device for generating resulting electromagnetic radiation. USE - Device for generating resulting electromagnetic radiation. ADVANTAGE - The determined spectral range is provided through the optical opening by the radiations, so that the spectral composition of the electromagnetic radiation resulted by the opening is adjusted by the selective activation of the radiation elements, thus providing the radiation generating device with changeable and/or adjustable spectrum in a simple manner
