The present invention relates to a moving head light fixture comprising: a base; a yoke rotatable connected to the base; a head rotatable connected to the yoke. The head comprises at least one light source generating light. An actuator is adapted to rotate the yoke or the head. Magnetic means is attached to the axel of the actuator and generated a magnetic field, which is perpendicular to the actuator axel. A magnetic encoder is fixed in relation to the axel and provides at an axel position signal based the magnetic field is indicative of the angular position of the axel in relation to the magnetic encoder. Indication means provides an indication signal when the yoke or head is positioned at a number of predetermined angular positions in relation. Processing means are adapted to control the moving head light fixture based on the actuator axel position signal and the indication signal.

The present invention relates to LED bar modules (2) where the LED groups are placed at a pixel board (6). The present invention further concerns a method for calibration of LEDs. It is the object of the invention to achieve a highly efficient LED bar for generating a bar of light. A further object of the invention is to store calibration data for each LED both electrically and mechanically close to the actual LED. Preferably, the main printed circuit is placed inside a heat conductive tube (4), where the pixel board (6) is placed outside the heat conductive tube (4) in a longitudinal recess, where the main printed circuit is placed inside an isolation cover (12). Hereby, it is achieved that the LEDs are placed on the outside of the tube (4) in a way where heat generated from the LEDs is conducted downwards to the tube (4). Inside the tube (4), the rest of the power electronics and also the light controlling electronics are placed.
摘要:
An illumination device having a number of light sources and a number of light collectors. The light collectors collect light generated by the light sources and convert the light into a source light beam propagating primarily along a primary optical axis. The light sources and the light collectors can be part of a light source module. The light source module can include a cooling module comprising a number of interconnected plane mounting surfaces angled in relation to each other, with the light sources arranged on said plane mounting surfaces. The cooling module can include a first side comprising the mounting surfaces and a second side comprising a number of cooling fins defining a number of radial air channels.
