Patent number: 10072834Abstract: Various embodiments relate to a cooling module for cooling a plurality of LEDs that includes a heat sink having a LED side sand a cooling side arranged at opposite sides of the heat sink. The LEDs arranged on the LED side and a first flow channel and second cooling channel are arranged adjacent to each other at the cooling side. The cooling module comprises a first blower and a second blower respectively configured to blow cooling air in a first flow direction through the first flow channel in a second flow direction through the second flow channel, where the first flow direction and the second flow direction being opposite each other. Certain embodiments also related to the light fixture comprising such cooling module and approaches for cooling a plurality of LEDs.Type: GrantFiled: April 3, 2015Date of Patent: September 11, 2018Assignee: MARTIN PROFESSIONAL APSInventors: Lars Barslund Kjaer, Carlsten Dalsgaard

Patent number: 9109788Abstract: The present invention relates to a moving head light fixture comprising: a base; a yoke connected to and rotatable relative to the base; a head connected to and rotatable relative to the yoke where the head comprises at least one light source generating a light. The yoke and the base are connected through a rotating base-yoke mechanism comprising a main shaft, a hollow shaft surrounding the main shaft and at least one bearing separating the main shaft and a the hollow shaft. The main shaft has increasing cross sectional dimensions and comprises a first annular flange located a distance from the part of the main shaft having the largest cross sectional dimension and in that the cross sectional dimension of the first annular flange is smaller than the largest cross sectional dimension of the main shaft.Type: GrantFiled: February 6, 2013Date of Patent: August 18, 2015Assignee: Martin Professional ApSInventors: Carsten Dalsgaard, Lars Barslund Kjær, Aleksander Henrik Von Preyss, Niels Jørgen Rasmussen, Uffe Kjærsgaard Toft

Patent number: 7942535Abstract: A light fixture having at least one light source for generating a beam of light, a plurality of color filters are rotatable into position to intercept the light beam. The color filters are fixed to the color wheel by a central spring which has a number of radial protruding tongues for fixation of the color filters. The color filters are removable yet are secured in a correct position by radial protrusions formed between the color filters an circular outer protrusion located outward of the color filters so as to form a cavity that surrounds the color filter at both sides as well as at outward. Inward of the color filters, they are fixed by the protruding tongue that presses them down and keeps them in place. This leads to a nearly perfect fixation of each color filter, which can be exchanged if necessary.Type: GrantFiled: April 30, 2008Date of Patent: May 17, 2011Assignee: Martin Professional A/SInventor: Lars Barslund Kjaer
