Abstract
A super cooler device including a thermo electric cooler on a digital micro mirror device.
Claims42
A light controlling system, comprising:
- a light controlling device which is controllable to control light on a pixel-by-pixel basis;
- a mounting structure for said light controlling device;
- and
- a condensation eliminating part, coupled to said light controlling device, and insulating at least one part of said light controlling device to eliminate condensation formed thereon.
1 more element
A method, comprising:
- using a light controlling device to control pixel by pixel reflection of light applied thereto;
- and
- cooling said light controlling device while reducing an amount of condensation formed on said light controlling device.
A system comprising:
- a light controlling device, which is controllable to control light on a pixel by pixel bases, having a first surface for reflecting light, and having a second surface opposite said first surface;
- and
- a heatsink and fan assembly having a first surface which is shaped to thermally connect to said second surface of said light controlling device, and having a fan operative to cool said first surface.
A method, comprising;
- using the light controlling device to reflect light that impresses on a light reflecting surface, on a pixel by pixel basis;
- cooling a surface of the light controlling device which does not actually receive the light;
- and
- wherein said cooling comprises connecting a heatsink to said surface of said light controlling device, and cooling the heatsink by blowing air in a direction substantially parallel to said light reflecting surface of the light controlling device.
1 more element
An apparatus, comprising:
- a light controlling device which is electrically actuable to control light on a pixel-by-pixel bases;
- a temperature sensing device, sensing at least one temperature of said light controlling device;
- and
- a cooling part, thermally coupled to said light controlling device, and operative to cool said light controlling device based on said at least one temperature which was sensed by said temperature sensing device.
1 more element
A method, comprising:
- using a light controlling device which is electrically able to control light on a pixel by pixel basis;
- sensing at least one temperature of said light controlling device and producing an output indicative thereof;
- and
- cooling the light controlling device based on said output.
