Abstract: Optical filters are used to compensate for changes in LED and pcLED performance resulting from technological advances in device design or manufacturing, with for example the filtered optical output from later generation devices matching or substantially matching the optical performance of earlier generation legacy devices. This can allow the advanced generation devices to be substituted in applications previously supported by the legacy devices, even if the optical performance of the unfiltered advanced generation devices does not satisfy the optical performance specifications required by the application. Somewhat paradoxically, the advantages of using the filters in combination with the advanced generation devices may arise from the filters making the optical performance of the devices worse according to one or more figures of merit.

Abstract: The disclosed end-to-end product customization systems and methods receive custom orders from customers or consumers, evaluate them, and generate production-ready custom orders that are able to be used by decorator to create the custom products. The system receives a customization option and an order file type in the custom order. The system or a third party evaluates that customization option to identify a change order that is required and also determines a conversion recommendation to convert the order file type or a production-ready file type. The production-ready custom order is generated based on the change order and the conversion recommendation.

Abstract: A light-emitting device includes: a semiconductor diode structure, a reflector, a wavelength-converting layer, and an intermediate spacer between the diode structure and the wavelength-converting layer. The diode structure emits diode output light at a vacuum wavelength ?0 to propagate within the diode structure.
