摘要:
The invention relates to the controlling of a lighting system with a plurality of light sources, particularly to the semi-automatic commissioning of light sources of the lighting system or controlling of the creation of lighting scenes with the lighting system. A basic idea of the invention is to use a spatial coding of light for controlling a lighting system, particularly for commissioning of light sources of the lighting system instead of or in addition to the temporal light coding as applied in the prior art. An embodiment of the invention relates to a system for controlling a lighting system with a plurality of light sources (1, 2) comprising a light system controller (5) for controlling the light sources in that a spatial light pattern (11, 12, 21, 22) is created, which codes one or more attributes (512) of the light sources (511), and a light pattern capturing device (3) for capturing the created spatial light pattern and communicating (32, 52) with the light system controller (5) in order to enable the controlling of the one or more light sources based on the captured spatial light pattern. A spatial coding is particularly suitable for wallwasher light sources, and thus especially assists personnel in commissioning wallwasher light sources of a lighting system.

To enable the LED circuit arrangement (1) to be driven at an operating voltage, the LED light source (3) comprises a first and a second LED unit (8, 9), each having one light emitting diode, controllable switching means (10) to connect said LED units (8, 9) with said reactive element (6) in a low voltage mode and a high voltage mode and a control unit (12). The LED light source (3) shows a first forward voltage in said low voltage mode and a second forward voltage in said high voltage mode, said second forward voltage being higher than said first forward voltage. The control unit (12) is adapted to control the current through the LED light source (3) by setting the switching means (10) to said low voltage mode when the current, supplied to the LED light source (3), corresponds to a first threshold value (30) and by setting the switching means (10) to the high voltage mode when said supplied current corresponds to a second threshold value (31).

The present invention relates to an illumination device comprising at least one light source and a reflector system forming a spotlight (1), one or several actuators (5) arranged to pivot the spotlight (1) relative in a mounting base (4) for varying an illumination angle, and a camera (13) attached to the spotlight (1) and aligned to acquire images of an illumination region (7) to which the spotlight (1) is directed. 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).

The invention relates to a circuit (2) comprising at least two parallel-connected light-emitting diodes (4, 5) opposite poled in a first parallel branch (12) and comprising at least two parallel-connected light-emitting diodes (6, 7) opposite poled in a second parallel branch (13), and also comprising a capacitor (8) and a coil (9). According to the invention, the first parallel branch (12) has a capacitor (8) and the second parallel branch (13) has the coil (9). On account of the capacitive parallel branch (10) and the inductive parallel branch (11), idle currents arise which are phase-shifted with respect to one another. The idle currents compensate one another and light changes of the oppositely-poled diode pairs take place at different points in time. A light current is then smoothed.
