Abstract: A light module (100) is disclosed including a housing (20) made at least in part from a thermally conductive material and includes an annular recess. A sealant (23) disposed in the annular recess and an optical plate (10) disposed in the housing (20). A portion (10a) of the optical plate (10) is disposed over the annular recess (21) and the sealant (23) forms a bond between the housing (20) and the portion (10a). An LED module (11) disposed between the housing (20) and the optical plate (10). At least some of the heat generated by the LED module 11 is conveyed to the housing (20) and dissipated. The light module (100) may also include a fastener (12) and the housing (20) may include a fastener stop (22). The fastener (12) is connected to the housing (20) and supports the optical plate (10). The fastener (12) is prevented from exerting excessive pressure on the optical plate (10) by the fastener stop (22).

Abstract: According to certain embodiments, a system for installing a plurality of LED luminaires are provided by partially supporting the LED luminaire while aligning and securing the connections with easy. The system also allows for thermal expansion and contraction and further improves aesthetic by hiding the power line. A bracket having a pair of support legs extending from one end and a mounting panel extending from at the other end is provided. A pair of T-rails on the housing is configured to slidably engage with the pair of support legs at a predetermined angle and tilted at a substantially horizontal level for a subsequent fastening to secure mounting of the housing onto the bracket.

Abstract: Exemplary tapered polymer optical probes (TPOPs), are highly customizable probes for characterization of photonic integrated circuits that move the optical infrastructure from on-chip to off-chip while providing additional utility than the on-chip infrastructure. TPOPs can be customized to meet specific coupling requirements, support the efficient use of on-chip area, provide in-situ tunability, and can access photonic devices in environments that are usually difficult to work in.
