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.

Light-emitting devices

Methods of forming light-emitting structures, as well as related devices and/or systems are described. In some cases, the methods utilize a layer transfer and/or layer separation step(s) used to form such structures.

Methods of forming light-emitting structures

Light emitting devices, and related components, processes, systems and methods are disclosed.

Light-emitting devices for liquid crystal displays

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.

Switching device integrated with light emitting device

Light-emitting devices can include a package that supports one or more light-emitting die (e.g., light-emitting diode die, laser diode die) and which can ensure mechanically stability, can facilitate electrical and/or thermal coupling with light-emitting die, and can manipulate the manner by which light generated by the die is emitted out of the light-emitting device. The package can also facilitate the integration of the light-emitting devices in various components and systems. For example, suitable packages may facilitate the use of light-emitting devices in components and systems such as light-emitting panel assemblies, LCD back lighting, general lighting, decorative or display lighting, automotive lighting, and other types of lighting components and systems.

Light-emitting devices and related systems

Illumination assemblies, components, and related methods are described. An illumination assembly is provided that comprises a plurality of illumination tiles each having a light emission surface. The plurality of illumination tiles are arranged in a two-dimensional array. The illumination tiles are constructed and arranged so as to provide a substantially contiguous illumination surface comprising the light emission surfaces of the plurality of the illumination tiles. Each illumination tile is illuminated by at least one solid state light-emitting device. A method of local dimming an illumination assembly of a display (e.g., LCD) backlight unit is also provided.

Tiled illumination assembly and related methods

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.

LED color management and display systems

A method for optimizing an LED lighting system cost includes steps of determining LED costs, power source costs, and total costs associated with a plurality of LED quantities, and identifying a lowest total cost as an optimal cost. A LED lighting system includes an LED operated by a constant-current driver at less than its maximum current capacity. A programmable controller including a feedback routine is used to compensate for intensity drift as an LED ages. Other embodiments of LED lighting systems include multiple LEDs producing light having various spectrums to optimize the lighting system efficiency and the effectiveness. A charge controller including an MPPT routine is advantageously employed with a LED lighting system powered by a limited-capacity power source.
