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.

  • Patent number: 9182094
    Abstract: An optical system that collects 100% of the light emitted from the light source and effectively directs it into the desired beam pattern. This is achieved by a combination of different optical control methods including reflector and lens optics. The cost is controlled by a design that reduces the optical part count to 2 main components, which reduces manufacturing and assembling time and maintains proper alignment to the light source and system.

  • Patent number: 9166112
    Abstract: In a light emitting module 40, a light wavelength conversation ceramic 52 converts the wavelength of the light emitted by a semiconductor light emitting element 48 then emits the light. An optical filter 50 transmits the blue light Lb mainly emitted by the semiconductor light emitting element 48 and reflects the yellow light Ly whose wavelength has been mainly converted by the light wavelength conversion ceramic 52. The optical filter 50 is provided on the surface of the light wavelength conversion ceramic 52. The light emitting module 40 is manufactured by: the process where the optical filter 50 is provided on at least one surface of the light wavelength conversion ceramic 52; and the process where the semiconductor light emitting element 48 and the light wavelength conversion ceramic 52 are arranged such that the light emitted by the semiconductor light emitting element 48 is incident into the light wavelength conversion ceramic 52.

  • Patent number: 9142711
    Abstract: A tunable color LED module comprises at least two sub-modules, each comprising an LED, a wavelength converting element (WCE) and a reflector cup. The total light emitted by the module comprises light generated from each LED and WCE and the module is configured to emit a total light having a predefined color chromaticity when activation properties of the LEDs are managed appropriately. The total light may have a broad white emission spectrum. The module combines the benefits of a low cost with uniform chromaticity properties in the far field, and offers long and controlled lifetime at the same time as flexibility and intelligence of tunable color chromaticity, Color Rendering Index (CRI) and intensity, either at manufacture or in an end user lighting application. A controlled LED module system comprises a control system for the managing activation properties of the LEDs in the sub-modules. Also described is a method of manufacture.
