The spotlight (1) is designed to comprise a central region from which the illumination region (7) is visible and which does not reflect or emit light of the light source towards the illumination region (7), wherein the camera (13) is arranged in said central region on an optical axis (14) of the spotlight (1). With the proposed illumination device an exact aiming of the spotlight (1) can be achieved even in applications in which the illuminated region (7) is close to the spotlight (1) without causing undesired shadows in the illumination region (7). ## Claims ### Claim 1 An illumination device comprising at least one light source and a reflector system forming a spotlight, wherein said reflector system is formed of an optics comprising a first curved reflective element with a concave reflecting surface and a central opening and a second reflective element with a reflecting frontside and a non-reflecting backside on the optical axis, the second curved reflective element being smaller than the first curved reflective element and designed and arranged to reflect the light of the light source entering along the optical axis through the central opening from the reflecting frontside to the concave reflecting surface of the second reflective element to collimate the light to form an illumination region without shadows, one or several actuators arranged to pivot the spotlight in a mounting base for varying an illumination angle of a light beam emitted by said spotlight, and a camera attached to the spotlight at the backside of the second reflective element and aligned to acquire images of the illumination region to which the spotlight is directed, wherein said spotlight comprises a central region from which the illumination region is visible and which does not reflect or emit light of the light source towards the illumination region, said camera being arranged in said central region on an optical axis of the spotlight. ### Claim 2 (depends on 1) The device according to claim 1, wherein said actuators are controllable via a control station distant from said spotlight. ### Claim 3 (depends on 2) The device according to claim 2, wherein said camera is connected through wire or wirelessly to a monitor for displaying the images of the illumination region. ### Claim 4 (depends on 3) The device according to claim 3, wherein said control station comprises a graphical user interface to allow a user to mark a point or region of interest in said images and wherein said actuators are automatically controlled by said control station to aim the spotlight at the point or region of interest. ### Claim 5 (depends on 1) The device according to claim 1, wherein said light source comprises several LEDs of different colors and a mixing system to mix light emitted by the LEDs before impinging on said reflector system. ### Claim 6 (depends on 1) The device according to claim 1, wherein the light source and at least a main reflection element of the reflection system are movable relative to each other along the optical axis for varying an aperture angle of the light beam emitted by the spotlight, wherein the camera comprises an optical system adjustable to vary an angle of view of the camera, and wherein said relative movement of the light source and the main reflection element and said adjustment of the optical system of the camera are coupled to be performed synchronously such that the illumination region always coincides with a region imaged by the camera. ### Claim 7 (depends on 6) The device according to claim 6, wherein the spotlight comprises one or several electrically driven actuators for performing the relative movement of the light source and the main reflection element and wherein the camera comprises one or several electrically driven actuators for adjusting the optical system.
