摘要:
The invention described relates to an arrangement, and to a method for the production of such an arrangement, which serves for generating mixed light. For this purpose, a semiconductor chip emitting electromagnetic primary radiation has a luminescence conversion element in the beam path of the primary radiation. The arrangement further comprises a connecting element and a carrier element, wherein the carrier element supports and forms the luminescence conversion element and the connecting element.
摘要:
Disclosed is a surface-mounted component comprising an optoelectronic semiconductor chip (1), a molded member (2) that is molded onto the semiconductor chip (1), an assembly area (3) which is formed at least in some points by a surface of the molded member (2), and at least one terminal point (4a, 4b) which is overlapped laterally by the molded member (2) or extends flush with the molded member (2). Also disclosed is a method for producing such a component.
摘要:
The invention relates to a wavelength-converting reactive resinous compound (5), which is reacted with a wavelength-converting luminous substance (6) and with a thixotropic agent, whereby the luminous substance contains inorganic luminous substance particles. The thixotropic agent exists, at least in part, in the form of nanoparticles. The invention also relates to methods for producing the reactive resinous compound and to light-emitting diode components having reactive resinous compounds of this type.
摘要:
The invention relates to a luminescence conversion of LED which uses a blue emitting chip and two illuminating substances, whereby one emits a red and the other a yellow to green. Both illuminating substances are separated upstream from the chip.
摘要:
The invention relates to a light-emitting component provided with at least one primary radiation source which emits an electromagnetic primary radiation during the operation thereof, and at least one luminescence conversion element which is used to convert at least one part of the primary radiation is converted to radiation of a different wave length. A filter element provided with a plurality of nanoparticles is arranged upstream from the luminescence conversion element in the direction of radiation of the component. The nanoparticles comprise a filter substance which selectively reduces the intensity of radiation of at least one spectral partial range of undesired radiation by absorption.
