    摘要: A thermal conductivity and phase transition heat transfer mechanism has an opto-luminescent phosphor contained within the vapor chamber of the mechanism. The housing includes a section that is thermally conductive and a member that is at least partially optically transmissive, to allow emission of light produced by excitation of the phosphor. A working fluid also is contained within the chamber. The pressure within the chamber configures the working fluid to absorb heat during operation of the lighting device, to vaporize at a relatively hot location at or near at least a portion of the opto-luminescent phosphor as the working fluid absorbs heat, to transfer heat to and condense at a relatively cold location, and to return as a liquid to the relatively hot location. Also, the working fluid is in direct contact with or contains at least a portion of the opto-luminescent phosphor.

    摘要: Systems and methods for determining a position of an object are provided by the present invention. Light is captured by at least one collector. Each collector has a first opening through which light enters that is larger than a second opening through which light exits. The exiting light is used by at least one light detector to generate signals. The position of the object is determined based upon the generated signals.
