Abstract: In described examples, an image-generating panel is arranged for modulating a projection beam to include a modulated optical image. A cooling device is arranged to transfer heat received from the image-generating panel to a heat sink. The cooling device is arranged to receive the projection beam on a first side and to transmit the projection beam from a second side. The heat received from the image-generating panel can include heat generated by the image-generating panel in response to incidental sunlight.

Abstract: Scanning mirror based display system and method. A method comprises sampling a scanned light provided by a scanning mirror, converting the sampled scanned light into an electrical signal, analyzing the electrical signal to determine a position of the scanned light, and controlling the light source or the scanning mirror based on the analyzed electrical signal. The electrical signal based on the sampled scanned light may be used to ensure proper operation of the scanning mirror display system, such as determining failure of the scanning mirror, proper rendering of colors, determining whether the scanned light is following a desired scan path at a desired scan rate, and so forth.

Abstract: A packaged electronic device includes a substrate with an upper surface interrupted by a well formed in the substrate. The well has a substrate bottom surface and a substrate sidewall. An electronic device is located in the well over the substrate bottom surface and has a device top surface and a device sidewall. A trench is bounded by the substrate bottom surface, the substrate sidewall and the device sidewall. An encapsulant at least partially fills the trench and contacts the substrate sidewall and the device sidewall. The encapsulant has a first elevation on the substrate sidewall with respect to the substrate bottom surface and a second elevation on the substrate device sidewall with respect to the substrate bottom surface that is at least about 35% greater than the first elevation.

Abstract: To improve the cooling efficiency and ensure uniform cooling of all portions of the inside back surface of the reflector, a deflector (108) has been developed. The air deflector (108) typically encircles the lamp (102) allowing air (110) to flow between the deflector (108) and the lamp (102). This air (110) cools the lamp (102). Air (112) passing between the deflector (108) and the reflector (100) is deflected outward to cool the inside surface of the reflector near the lamp (102). Because the deflector (108) is small and is located directly behind the lamp (102), it does not block any of the useful light generated by the lamp (102). The light striking the deflector (108) from the lamp (102), if not for the deflector (108), would have passed through the opening in the reflector (100) and would have been lost. The deflector (108) typically has a number of vanes around the perimeter of a cylindrical body portion.

Abstract: Provided in one embodiment is a heatsink. The heatsink may include a rib having first and second opposing surfaces. The heatsink may further include a first set of fins extending from the first surface, and a second set of fins extending from the second surface. The heatsink may further include one or more mounts configured to secure one or more solid state illumination sources to the rib.
