Abstract:
An apparatus for illumination having a housing suited for in ground use, which contains at least one lamp which is surrounded by a reflector, has a light changer, and a controller for controlling at least the lamp and the light changing means. To reduce the content of moisture air containing evaporated water is able to be released from the lamp to the surroundings and only air without moisture is allowed to enter the in-ground lamp. This can be achieved with a housing with an outer casing which has at least one diaphragm covering at least one downwardly directed opening which is open towards the surrounding environment, the diaphragm being permeable for moisture for transmission from the inside of the housing to the outside, but is water-tight inward from the outside. Even in a situation where the apparatus is completely overflowed, the diaphragm prevents water penetrating from the outside.
Abstract:
The present invention relates to an illumination device where a number of light sources are arranged on a heat sink and adapted to emit light in substantially the same direction. The heat sink comprises a first cooling plate and a second cooling plate. A first part of the light sources are arranged on the first cooling plate and a second part of the light sources are arranged on the second cooling plate. The first and second cooling plates are separated by a distance and a flow channel is defined there between. The flow channel allows cooling fluid to flow between the first cooling plate and the second cooling plate whereby the light sources can be cooled by the cooling fluid. The heat sink comprises further a number of light passages allowing light to propagate from the second cooling plate, towards the first cooling plate and through the first cooling plate.
Abstract:
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 a light controller for controlling a lightning system, where the lightning system comprises a number of light emitting devices such as controllable light fixtures, controllable light emitting visual devices and/or controllable display devices adapted to emit video content. The light controller comprises a first slide controller, a second slide controller, and a locking mechanism adapted to fix the first slide controller and the second slide controller in relation to each other, such that movement of at least one of the slide controllers forces the other slide controller to perform a corresponding movement.
Abstract:
The present invention relates to an illumination device comprising a number of light sources generating light and a number of light collecting means adapted to collect the generated light and to convert the collected light into a number of light beams that propagate along an optical axis. The light sources are arranged in a first group and a second group of light sources and the first and second group of light sources emits light having different spectral distribution. The light sources and the light collecting means are movable in relation to each other and can be positioned in a number of mixing positions, where in the number of mixing positions the light collecting means are adapted to collect at least a part of the light emitted by the first group of light sources and at least a part of the light emitted by said second group of light sources and to convert the collected light into number of mixed light beams.
Abstract:
An illumination device or method of generating illumination using an illumination device is described with two light sources with different spectral distribution a number of displaceable light collectors collecting light from the light sources where in one mixing position receiving light from both light sources where at least one of the light sources has two independently controllable light emitting areas and in one mixing position the collecting area collects light form the first light emitting area and substantially not from the second light emitting area. Further an unrelated illumination device with at least one Light Emitting Diode, LED and a current spreader connected to and covering a first area of a first side of the lead, spreading current in an irregular pattern and a current controller controlling current flowing through the first current spreader. The current spreader can be patterned to produce a round beam illumination or illumination in a form of a static picture or logo. A round beam illumination can better cooperate with an optical system of lenses in an illumination device. Further the current spreader can be patterned to have lower current density in the centre to reduce/avoid temperature hotspot in the centre and obtain a more even die temperature.
