Abstract
A lighting device for professional illumination. The device includes a main housing having a front opening, a first light source, a first reflector configured to receive at least a portion of light emitted by the first light source and to reflect at least a portion thereof, and a second reflector configured to receive at least a portion of light reflected by the first reflector and to reflect at least a portion thereof. The lighting device is configured to emit at least a portion of light reflected by the second reflector out of the lighting device through the front opening. The lighting device further includes an actuator configured to move the first reflector or the second reflector in relation to each other in response to a predetermined control signal.

A lighting device configured for professional illumination, the lighting device comprising:
- a main housing comprising a front opening,
- a first light source configured to emit light,
- a first reflector configured to receive at least a portion of light emitted by the first light source and to reflect at least a portion thereof,
- a second reflector configured to receive at least a portion of light reflected by the first reflector and to reflect at least a portion thereof,
- wherein the lighting device is configured to emit at least a portion of light reflected by the second reflector out of the lighting device through the front opening,
- the lighting device further comprising an actuator configured to linearly move the first reflector in relation to the second reflector along a predetermined direction or along a longitudinal direction, wherein the actuator is further configured to move the first reflector in response to a predetermined control signal,
- wherein the first reflector has a reflecting surface configured to reflect at least a portion of light emitted by the first light source, and
- wherein the actuator is arranged on the other side than the reflecting surface of the first reflector, and wherein the first reflector is arranged between the first light source and the actuator.
A lighting device configured for professional illumination, the lighting device comprising:
- a main housing comprising a front opening,
- a first light source configured to emit light,
- a first reflector configured to receive at least a portion of light emitted by the first light source and to reflect at least a portion thereof,
- a second reflector configured to receive at least a portion of light reflected by the first reflector and to reflect at least a portion thereof,
- wherein the lighting device is configured to emit at least a portion of light reflected by the second reflector out of the lighting device through the front opening,
- the lighting device further comprising an actuator configured to move the first reflector or the second reflector in relation to each other,
- wherein the actuator is further configured to move the first reflector or the second reflector in response to a predetermined control signal,
- wherein the actuator comprises a spindle or a spindle shaft or other connecting element connected to the first reflector wherein movement of the spindle or spindle shaft or other connecting element causes movement of the first reflector and wherein the first reflector further comprises a cap unit arranged through the first reflector, and
- wherein the cap unit is configured to receive at least a part of the spindle or spindle shaft when the first reflector is moved at or near a first end position.
