The present invention provides a method and apparatus for using light emitting diodes for curing and various solid state lighting applications. The method includes a novel method for cooling the light emitting diodes and mounting the same on heat pipe in a manner which delivers ultra high power in UV, visible and IR regions. Furthermore, the unique LED packaging technology of the present invention utilizes heat pipes that perform very efficiently in very compact space. Much more closely spaced LEDs operating at higher power levels and brightness are possible because the thermal energy is transported in an axial direction down the heat pipe and away from the light-emitting direction rather than a radial direction in nearly the same plane as the “p-n” junction.

A vehicle air conditioning system includes a space air conditioning unit for blowing conditioned air into a passenger compartment, a seat air conditioning unit for blowing air into a vehicle seat, and a control unit for controlling the space air conditioning unit and the seat air conditioning unit. The control unit includes space controlling means for controlling the space air conditioning unit in accordance with a space control value calculated based on a space target air temperature, and seat controlling means for controlling the seat air conditioning unit in accordance with a seat control value calculated based on the space target air temperature. Further, the seat controlling means includes a first seat air conditioning means which determines the seat control value in a steady air conditioning state of the passenger compartment, and a second seat air-conditioning means which determines the seat control value in a transition air-conditioning state of the passenger compartment.

A mass and heat exchanger includes at least one first substrate with a surface for supporting a continuous flow of a liquid thereon that either absorbs, desorbs, evaporates or condenses one or more gaseous species from or to a surrounding gas; and at least one second substrate operatively associated with the first substrate. The second substrate includes a surface for supporting the continuous flow of the liquid thereon and is adapted to carry a heat exchange fluid therethrough, wherein heat transfer occurs between the liquid and the heat exchange fluid.

Cooling devices are provided to reduce a person's temperature by evaporative, convective, and / or conductive cooling. One such device maximizes evaporative cooling by aiding the flow of air to the person and the removal of vapor-laden air from the person. An upper sheet and a base sheet are adhered to define numerous elongated, parallel, inflatable cooling chambers separated by flat connecting membranes. Ventilating cross-members interconnect the cooling chambers. Air enters the chambers through an inlet, exits the chambers toward the person through air permeable regions of the base sheet. Air heated by the person's body exits the device upward through evaporation openings in the connecting membranes. The foregoing device, or different variations thereof, may be modified for use in conductive cooling by adding an absorbent sheet beneath the base sheet, or substituting the absorbent sheet for the base sheet itself. This device directs air upon the wetted absorbent sheet to cool this layer, and thereby conductively cool the patient's skin in thermal contact with the absorbent sheet. As one example, this device may be configured in serpentine shape, with multiple winding segments. The device may include body-contour slits extending inward from the perimeter, permitting the device to conform to a person's legs and outstretched arms. Cooling devices may also include optional features to enhance thermal contact between the absorbent sheet and the person's skin, and / or to prevent water runoff from the cooling field.
