| Title: |
Lighting Apparatus with Luminophore on a Moveable Carrier |
| Abstract: |
The lighting device (11) has at least one light generation device (12)
for generating a primary light (P), a first luminophore (16) for
converting the wavelength of the primary light (P) to a first secondary
light (S1), and a second luminophore (20) for converting the wavelength
of the primary light (P) to a second secondary light (S2), the first
luminophore (16) being located on a movable support (15), which is
provided in order to alternatively move the first luminophore into and
out of a beam path of the primary light (P), and the second luminophore
being located on a stationary support (21). The invention also relates to
a method for generating wavelength-converted secondary light from primary
light with alternating irradiation of a first luminophore located on a
movable support and of a second luminophore located on a stationary
support by the primary light. The invention can be used, for example, as
a projection device for film and video projection, in endoscopy, for
lighting effects in the entertainment industry, for medical irradiations
as well as in the automobile industry, in particular as a head light for
motor vehicles.
