Abstract: The present invention relates to a light collector adapted to collect light from a plurality of light sources and where the light collector comprises a plurality of lenslets collecting light from the light sources and convert the light into a plurality of light beams propagating along an optical axis. The lenslets are arranged in a dense pattern, where at least 12 outermost adjacent lenslets is located along an outer circular boundary having the same radial distance to a center of the light collector. The dense pattern has been obtained by optimizing a packaging density defined by a ratio of a sum of areas of circular cross sections of the lenslets and an area of the outer circular boundary and that the packaging density is at least 0.79.

Abstract: The present invention relates to a moving head light fixture comprising a base, a yoke and a head. The yoke is rotatable in relation to the base around a yoke axis. The head is rotatable around a head axis in relation to the yoke and comprises at least one beam light source arranged in the head housing where the beam light source generates a light beam exiting the housing. A part of the head housing and/or the said yoke shell is illuminated at least one pixel light source and form an illuminating part formed in a transparent material allowing light from the pixel light source to pass through the illuminating part and the illuminating part is substantially rotational symmetric in relation to said yoke axis. A plurality of such moving head can from a graphical display.

Abstract: A light fixture including a stepper motor comprising a stepper motor stator and a stepper motor rotor. The stepper motor rotor includes a stepper motor axle and is rotatable around a stepper motor axis. The stepper motor is connected to a movable object and is configured to move the movable object in relation to a reference point. A damping mass is attached to the stepper motor axle. The damping mass has a rotational inertia in relation to the stepper motor axis which is at least as large as the rotational inertia of the stepper motor rotor in relation to the stepper motor axis. A method of damping the sound generated by a light fixture comprising a step of attaching a damping mass to a stepper motor axle.

Abstract: A method of determining pose of a moving head light fixture, comprising a support structure and a rotatable structure rotatable connected to the support structure. The rotatable structure comprises at least one light source generating a light beam and a position indicating the position of the position indicator. The method comprises the steps of arranging the position indicator at at least three different positions around the axis of rotation by rotating the rotatable structure; and a step of obtaining the position of the position indicator at each of the at least three different positions. The pose of the moving head light fixture can be obtained based on the obtained positions.

Abstract: The present invention relates to a projecting light fixture comprising at least one LED generating light beam and a projecting system positioned configured to project the light beam along an optical axis. A beam shaping object is arranged between the LED and the projecting system and comprises a least two different beam shaping patterns, which can be arranged in the source light beam upon rotation of the beam shaping object in relation to the light beam. An actuator is configured to continuously rotate the beam shaping object in relation to the source light beam in order to alternately arrange the beam shaping patterns in the light beam. The projecting light fixture comprises a synchronizer providing a synchronizing signal indicative of: the rotation speed and/or the angular position of the beam shaping object; the position of beam shaping patters in relation to the light beam. Where a controller is configured to toggle the LED between a LED on-period and a LED off-period based on the synchronizing signal.
