Abstract:
The present invention relates to a moving head light fixture, which moving head light fixture comprises a light generating head, which head is carried in a yoke, which head is rotatable to the yoke, which yoke is rotatable to a base, which head comprises electronic circuits for LED control. The moving head comprises a first and a second end section, which first and second end sections comprise a number of light sources. Hereby it can be achieved that the moving head light fixture which is able at the same time to generate a light into different directions. By having independent control over the light sources in both directions, it is possible to control the light from an external controller independently in both directions. The light sources could be formed out of a multiple of single light sources generating light at different colors. In this way it should be possible by means of an external command to the moving head light fixture to control the color of the light as well in the front direction and also in the opposite rear direction.

Abstract:
The present invention relates to a system for cooling a display in a moving head projector, which moving head comprises a head rotatable in relation to a yoke, which yoke is rotatable in relation to a base, which base comprises at least one display, which display is cooled. It is the object of the invention to protect and cool a LCD display. The object can be fulfilled by a system if modified by protecting the display by a front cover where between front cover and the display is formed a cooling channel, in which cooling channel an air stream is flowing. Hereby can be achieved a highly effective combined protection and cooling of a display.
Abstract:
A light fixture having a head, a yoke and a base, the yoke having handles for carrying the light fixture. Placing the handle at the upper part of the yoke is very efficient if the light fixture is to be carried. Access to these handles is possible directly in a flight case because there is sufficient space for getting access to the handles above the yoke. In terms of small light fixtures, an individual can easily carry the light fixture by these handles and safely lift the light fixture from a flight case. In the case of very large light fixtures, two individuals can lift the fixture from both sides of a flight case and can carry the light fixture by the handles. By placing the handles as high as possible in relation to the light fixture, the light fixture can be carried in a very stable manner.
Abstract:
A lighting fixture having at least one internal processor and at least one fixed element to which controllable moving elements are rotatably fastened, one moving element having at least one light source that generates a beam of light. Information concerning positions of moving components in a lighting fixture is automatically achieved. Correct position indication at start up is obtained without moving the components to their end stops for finding set points for step motors by the provision of at least one absolute encoding device, which encoding device indicates the angular movement of a first input axel in relation to the encoding device, which absolute encoding device has a gearbox with a second internal axel, which first input axle drives a first toothed timing wheel, intermeshing with a second toothed timing wheel that rotates the second axel with a angular velocity different from the angular velocity of the first input axle.
Abstract:
The present invention relates to a method and an apparatus primarily for entertainment, which method or apparatus comprises an electronic control system, comprising at least one processor, which processor controls and stores at least some operational parameters during operation of the apparatus. The scope of the invention is to achieve access to data stored in an entertainment system or apparatus in periods of non-operation. This can be achieved if the apparatus comprises a RFID tag, which RFID tag can be communicating with the processor during operation, which RFID tag comprises at least one memory, which memory can contain copy of data segment representing at least one operational parameter for the apparatus, which RFID tag can be accessible from outside the apparatus in an operational or non-operational period, where an external device can read or write in the data segment in the memory in the RFID tag. It is hereby achieved that data could be transmitted in and out of the RFID tag during operation of an apparatus. Data transmitted out from the RFID tag could be information about addresses for normal communication with the apparatus using the DMX protocol as an example. These addresses could then be exchanged from the outside if the address for a specific apparatus has to be changed. After operation of an entertainment apparatus, for example when it is ready for transportation for a performance, an RFID scanner could be used to control failures or critical parameters in the apparatus so that apparatuses that show any critical parameters are sent for repair while operators showing normal activity will be transported for the next show.
Abstract:
A system and a method for internal communication in a lighting system, which lighting system comprises a computer for controlling the lighting system, in which system a number of motors or actuators are controlled by the computer system, which motors or actuators control the operation of light effect components in relation to the lighting system, where the computer further controls a number of functions in the lighting system, which computer is controlled by input means. The computer system can be centrally placed where control information generated in the computer system is distributed to a number of distributed drivers over a data bus, where distributed drivers are in operation physically close to the motors or actuators, where distributed drivers based on data received from the data bus, perform control of actuators or motors.
Abstract:
The present invention relates to a method for forming a light beam, and to a light assembly comprising at least one light source placed in conjunction with a fixed reflector, which reflector forms a beam of light into light forming means, which light assembly comprises a front lens, where the light forming means at least comprise a light deflecting means for changing the light angle of the light beam after passing through the front lens. The object of the invention is to achieve a light assembly, where major optical components are mechanically fixed in relation to a housing for achieving a light assembly, the mass centre of which changes only slightly during operation. A further object is to achieve a closed light assembly having openings in the case only for cooling. This can be achieved, if the front lens has a central part that differs from the surrounding parts of the front lens, and where the light deflecting means in a first position concentrates the light beam into the central part of the front lens to generate a wide-angle light beam, and where the light deflecting means in a second position distributes the light beam over the entire front lens to generate a narrow-angle light beam, and where the light deflecting means is connected with a first actuator, and where the light deflecting means is movable between the first and the second position. A very efficient wash light zoom system can hereby be achieved, where the front lens has different characteristics between its centre portions and the rest of the surrounding part of the front lens. Because of the internal light deflecting means, the front lens does not have to be movable with respect to the housing. Furthermore, the reflector and the lamp are held in a fixed position. This may result in constant control of the air flowing around the optical components.
