Embodiment Construction

[0092] figure 1 A sectional side view of a floodlight 1 with a wavelength converter 2 according to the first exemplary embodiment is shown. The floodlight 1 can be, for example, a vehicle floodlight, a floodlight for stage lighting or a floodlight for effect lighting, but is generally not restricted thereto.

[0093] The wavelength converter 2 has a secondary light S ( For example, a converter layer 3 which is partially converted into yellow secondary light S or completely converted into red, green and blue secondary light S) serves as the top layer. The wavelength converter 2 is designed as a solderable SMT component.

[0094] The searchlight 1 has a primary light source 4 for illuminating the converter layer 3 , which can have, for example, one or more lasers. The light emitted by the primary light source 4 impinges on the front side 5 of the converter layer 3 . Secondary light S or a mixture of unconverted primary light P and secondary light S can also be emitted from t...

Abstract

A wavelength converter includes a converter layer for at least partly converting primary light of a first spectral composition into secondary light of a second spectral composition, an electrically insulating first insulation layer arranged below the converter layer, a mirror being arranged at the front side of said insulation layer facing the converter layer, at least one conductor track which isarranged at the first insulation layer and which extends laterally at a distance from the mirror, mutually spaced apart contacts extending through the first insulation layer, of which contacts in each case at least two contacts electrically connect a conductor track to a rear side of the first insulation layer, and mutually spaced apart electrically conductive solder connection volumes arranged below the first insulation layer, said solder connection volumes being electrically connected in each case to one of the contacts. The converter is particularly applicable to searchlights, for exampleto vehicle searchlights, searchlights for stage lighting or searchlights for effect lighting.

Description

technical field [0001] The invention relates to a wavelength converter having a converter layer for at least partially converting primary light of a first spectral composition into secondary light of a second spectral composition. The invention also relates to a converter assembly having at least one such wavelength converter, wherein at least one wavelength converter is attached to at least one carrier substrate of the converter assembly and is electrically connected to the carrier substrate. The invention also relates to a lighting device having at least one such converter component and at least one primary light source for irradiating the converter layer with primary light. The invention also relates to a searchlight having at least one such lighting device. The invention is particularly applicable to searchlights, such as vehicle searchlights, searchlights for stage lighting or searchlights for effect lighting.
