  • Publication number: 20160294471
    Abstract: An example of a power and modulation circuit utilizes a very high frequency switching power converter to supply drive current power to cause a solid state light source to emit light. The power converter is configured to convert power from a power source to direct current to supply via the output to the light source, at least in part by a switching function of the power converter at a very high frequency rate. The circuit, in such an example, also includes a control circuit coupled to be responsive to input data and control operation of the power converter so that the current output to drive the light source modulates the light emitted from the light source to also carry the input data.

  • Patent number: 8362703
    Abstract: Light-emitting devices, and related assemblies, systems and methods are described. Specifically, at least some of the embodiments relate to light-emitting devices including proximate switching element(s). The switching element(s) control the current, or power, supplied to the light-emitting devices.

  • Patent number: 8110835
    Abstract: A light emitting component can include a substrate, a light emitting device supported by the substrate, wherein the light-emitting device has first and second terminals, and a switching element supported by the substrate and having first and second terminals electrically connected to the first and second terminals of the light-emitting device, respectively. The switching element is configured to, at least in part, divert at least some current away from the light emitting device when the switching element is in a closed state. An electrical connection between the first terminal of the switching element and the first terminal of the light emitting device can have a length of less than 5 cm (e.g., less than 2 cm, less than 1 cm, less than 5 mm, less than 1 mm). A current regulator may be supported by a second substrate and can supply current to the light emitting device.

  • Patent number: 7959341
    Abstract: Illumination systems, which include at least one light source (e.g., LED and/or laser diode), light sensor, and a power source are described. In certain embodiments, a light sensor and a microprocessor are used to detect light emitted by a light source and to adjust the power signal provided to the light source at least partially based on the detected light. Some embodiments may enable the color point and/or brightness of the emitted light to be controlled at least partially based on the detected light. The illumination systems may be designed to be used as a liquid crystal display (LCD), general lighting apparatus, or any other illumination device.
