摘要： Illumination devices whose function are to inject light into backlights, particularly into backlights that incorporate a recycling cavity formed by a front (50) and back (52) reflector, are described. In some embodiments, the device includes a light source (59) disposed proximate the back reflector, and first (42) and second (44) reflecting structures. The first reflecting structure includes an inner reflective surface (41b) at least a portion of which is inclined to form a wedge with the back reflector. The wedge partially collimates and directs light from the light source generally away from the recycling cavity. The second reflecting structure receives light exiting the wedge and redirects such light into an injection beam directed into the recycling cavity.

摘要： A decollimator for a daylighting system includes a conical section having a circular end, a square end, and a conical shape tapering inwardly from the circular end to the square end. A mixing zone section is attached to the square end of the conical section and has a square cross sectional shape of a substantially constant cross sectional dimension. The decollimator also includes either a window with a converging Fresnel lens on the circular end of the conical section, a window with a diverging Fresnel lens on an end of the mixing zone section opposite the conical section, or both. When the conical section receives collimated light, the conical section, the mixing zone section, and the Fresnel lens together decollimate the light and provide the decollimated light out of the mixing zone section.

摘要： A thermal transfer donor element is disclosed that includes a substrate, a transfer layer, a light-to-heat conversion layer disposed between the substrate and the transfer layer, and an underlayer disposed between the substrate and the light-to-heat conversion layer. The underlayer manages heat flow between layers of the donor element during imaging. For example, the underlayer can increase heat transport from the light-to-heat conversion layer to the substrate to prevent overheating. The underlayer can also be used to insulate the substrate from heat generated in the light-to-heat conversion layer or to increase heat flow to the transfer layer during imaging. Managing heat flow using an underlayer can improve transfer properties and/or reduce defect formation during imaging.
摘要翻译：公开了一种热转移施主元件，其包括基板，转印层，设置在基板和转印层之间的光热转换层，以及设置在基板和光热转换层之间的底层。底层在成像期间管理施主元件的层之间的热流。例如，底层可以增加从光热转换层到基板的热传递，以防止过热。底层还可用于使基板与光热转换层中产生的热量绝缘，或者在成像期间增加到转印层的热流。使用底层管理热流可以改善成像过程中的转移特性和/或减少缺陷形成。
