Abstract: A laser-based fiber-coupled white light system is provided. The system includes a laser device comprising a gallium and nitrogen containing emitting region having an output facet configured to output a laser emission with a first wavelength ranging from 385 nm to 495 nm. The system further includes a phosphor member integrated with light collimation elements. The phosphor member converts the laser emission with the first wavelength to a phosphor emission with a second wavelength in either reflective or transmissive mode and mixed partially with laser emission to produce a white light emission. The system includes a transport fiber coupled to the phosphor member via the light collimation elements to receive the white light emission and deliver the white light emission remotely to one or more passive luminaries substantially free of electrical or moving parts disposed at remote distances from a dedicated source area.

Abstract: A camera flash comprises a solid-state light source (laser chip) operable to emit excitation light having an emission peak wavelength in a first wavelength range and a photoluminescence wavelength conversion component located remote to the light source. The photoluminescence wavelength conversion component comprises at least one photoluminescence material (phosphor) that is excitable by the excitation light and in response emits light having an emission peak wavelength in a second wavelength range. The light source is configured such that excitation light is incident on an area of the photoluminescence wavelength conversion component less than about 0.01 mm2. The photoluminescence wavelength conversion component can comprise a light reflective or light transmissive component.

Abstract: An LED component is provided, with light emission in the green-to-near UV wavelength range. The light-emitting semiconductor die is encapsulated with one or more silicone compounds, including a hard outer shell, an interior gel or resilient layer, or both. The silicone material is stable over temperature and humidity ranges, and over exposure to ambient UV radiation. As a consequence, the LED component has an advantageously long lifetime, in which it is free of “yellowing” attenuation which would reduce the green-to-near UV light output.

Abstract: An LED package includes a heat-sinking slug that is inserted into an insert-molded leadframe. The slug may include an optional reflector cup. Within this cup, the LED and a thermally conducting sub-mount may be attached. Wire bonds extend from the LEDs to metal leads. The metal leads are electrically and thermally isolated from the slug. An optical lens may be added by mounting a pre-molded thermoplastic lens and a soft encapsulant or by casting epoxy to cover the LED or by a cast epoxy lens over a soft encapsulant.
