Controllable LED Light Intensity for User Customization

Intelligent variable lighting systems for improved efficiency and customization. The lighting systems use occupancy and ambient light sensors to autonomously adjust LED brightness based on occupancy and light levels. The lighting will dim when no one is present and brighten when occupied. Transition delays can be adjusted to optimize the balance between energy savings and avoiding abrupt lighting changes. The systems can also be remotely managed to set dimming levels and delays.

LED lighting fixtures can produce a range of light colors and color temperatures to mimic natural sunlight and adapt to human circadian rhythms. The fixture has separate LED sections for high and low color temperature light, such as cool and warm white. The LED sections have different phosphors to generate distinct colors. The sections can be controlled independently to adjust the overall light spectrum and color temperature. This allows the fixture to mimic natural daylight and create lighting conditions that align with the body's biological clock.

A hybrid lighting and communications system that uses an orange nanowire LED combined with a blue laser diode to produce high-quality white light with tunable color temperature and good color rendering, while also enabling high-speed optical wireless data transmission. The system achieves data rates over 1 Gbps using on-off keying modulation of the blue laser, while also generating high-quality white light with a color rendering index over 80. The nanowire LED provides color tunability and intensity for the white light, while the blue laser enables high-speed data communication.

Modular LED lighting system for aquariums that provides customizable multi-color lighting. The lighting system has a housing with a bottom-mounted control region containing multiple channels for controlling different colored LED modules. The channels can be individually connected to LED modules of different colors. This allows users to mix and match various colored LED modules to create custom lighting colors. A switch on the housing controls power to the channels and thus the connected LED modules.

Highly efficient LED assembly for compact illumination in devices like displays. The assembly contains red, green, and blue LEDs mounted on a frame, with separate power traces for each color to control output independently. The frame design integrates a connector for easy connections. The LEDs can be selectively activated to adjust the color balance. This allows packing the LEDs closely together to improve mixing efficiency for white light without needing phosphors.

Modular solid-state lighting devices that allow easy replacement, upgrading, and customization of lighting units while fitting within existing lighting form factors. The lighting devices consist of removable modules containing solid-state light emitters and associated components like drivers and heat sinks. These modules can be interchanged in lighting fixtures to change light color, intensity, heat dissipation, and other characteristics. The modular approach extends lighting fixture lifetimes and enables upgrading or replacing components as needed.

A controlled linear LED light source for sorting machines that enhances imaging capability and sorting performance. The light source uses a modular LED illuminator with individual LED control that allows temporal, spatial, and spectral control of the light emitted. An external diffuser renders the light uniform. A computer network controls the LEDs to generate a multi-modal, multi-spectral light output with characteristics optimized for imaging and sorting.

A lighting assembly that is compact, easy to manufacture, and provides shielding against electromagnetic interference. The assembly uses multiple boards sandwiched together, rather than a single board, to allow independent adjustment and isolation of components like LED light sources and electronics. This avoids the need for complicated mechanical and electrical connections typically used in lighting assemblies. The sandwiched boards can be fixed together and adjusted to optimize the light output while reducing EMI issues.

Light-emitting device package that can change color and beam shape by selectively activating different areas of an addressable LED die. The LED die has multiple light-emitting junctions that can be independently controlled. The junctions can be turned on/off or dimmed to shape the light beam. Different phosphors can be selectively deposited on each junction to create a multi-color light source. By independently controlling the junctions, the package can create complex dynamic lighting effects.
