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.

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.
