Abstract
A super cooler device including a thermo electric cooler on a digital micro mirror device.
Claims22
A system, comprising:
- an electrically controllable device that is electrically controllable to control light on a pixel by pixel basis;
- and
- a cooling device, connected thermally to said electrically controllable device, and operating to actively cool said electrically controllable device, where said operating provides a first nonzero amount of cooling based on detecting a need for providing a first cooling amount, and where said operating provides a second nonzero amount of cooling, based on detecting a need for providing a second nonzero cooling amount, wherein said first nonzero cooling amount is different then said second nonzero cooling amount.
A system, comprising:
- an electrically controllable device that is electrically controllable to control light on a pixel by pixel basis;
- a cooling device, thermally coupled to said electrically controllable device, and cooling said electrically controllable device;
- and
- a controller for said cooling device, controlling said cooling device based on a temperature differential between a front surface of said electrically controllable device and a rear surface of said electronically controllable device.
1 more element
A method, comprising:
- operating an electrically controllable device that is electrically controllable to control light on a pixel by pixel basis, said operating comprising changing an applied light beam to create a light output;
- cooling said electrically controllable device, and cooling said electrically controllable device;
- and
- controlling an amount of a cooling device that is used to cool said electrically controllable device, based on a temperature differential between a front surface of said electrically controllable device and a rear surface of said electronically controllable device.
1 more element
A method, comprising:
- operating an electrically controllable device that is electrically controllable to control light on a pixel by pixel basis, said operating comprising changing an applied light beam to create a light output;
- and
- controlling cooling of said said electrically controllable device, wherein said controlling provides a first nonzero amount of cooling based on detecting a need for providing a first cooling amount, and where said operating provides a second nonzero amount of cooling, based on detecting a need for providing a second nonzero cooling amount, wherein said first nonzero cooling amount is different then said second nonzero cooling amount.
