Problems solved by technology

[0005] The carrier wheels are typically angled relative to one another and must be precisely synchronized, which entails considerable construction effort, for example due to the use of high-quality and thus expensive drive motors for the carrier wheels and due to the complex synchronization control

Embodiment Construction

[0049] figure 1 Shown is a lighting device 100 with: a primary light source in the form of a semiconductor laser 101; a bowl-shaped reflector 102; a first carrier wheel 103 with a phosphor region 104 and a reflection region 105 ; and a second carrier wheel 106 with a filter area 107 and a non-filtered light-transmitting area 108 .

[0050] The semiconductor laser 101 emits blue primary light P, more precisely obliquely, ie in a direction at an angle to the main emission direction E of the output beam D emitted from the second carrier wheel 106 . A flexibly configurable, in particular elongated arrangement of the lighting device 100 is thus possible.

[0051] In the illustrated first rotational position, the semiconductor laser 101 irradiates the outside of the reflector 102 , more precisely in the region in which a window 109 through which the primary light P is present is present. The primary light P emitted by the semiconductor laser 101 is thus radiated via the reflector ...

Abstract

A lighting device (200) has at least one luminescent substance region (104) that can be illuminated by a primary light source (101) and at least one optical filter region (107) that can be connected downstream of the at least one luminescent substance region (104). The at least one luminescent substance region (104) and the at least one filter region (107) are arranged at different heights on a common support wheel (203). The invention can advantageously be used in particular for vehicles, in particular for motor vehicles, in particular for vehicle headlights, as well as for general lighting and as medical lighting, in particular endoscope lighting.

Description

technical field [0001] The invention relates to a lighting device which has at least one phosphor region which can be irradiated by a primary light source and at least one optical filter region which can be accessed downstream of the at least one phosphor region, wherein not only At least one phosphor region is arranged on the rotatable carrier wheel, and at least one filter region is also arranged on the rotatable carrier wheel. The invention can be used particularly advantageously in vehicles, in particular in motor vehicles, in particular in vehicle headlights. The invention can also advantageously be used in general lighting and for medical purposes, for example as endoscopic lighting. Background technique [0002] In a lighting device of the type described at the outset, primary light can be generated by means of a primary light source. Hitherto, during operation of the luminaire, the primary light is incident on a disc-shaped, rotating first carrier wheel, which has ...
