Low-profile luminaire design for retrofit LED downlighting applications. The luminaire has a heat spreader, heat sink trim plate, and a light source mounted to the spreader. The spreader and sink are sized, shaped, and thermally coupled to effectively dissipate heat from the light source without requiring additional bulky heat-sinking components. This allows a compact form factor suitable for retrofitting into existing recessed light fixtures or junction boxes.

LED module for emitting mixed light, preferably white light, that can be used in lamps with small reflector sizes. The LED module has a circular light-emitting zone divided into flat sectors, like slices of a pie. Each sector can emit a different light spectrum. Phosphor can be added to the potting compound between the sectors to create white light. This allows producing a homogeneous mixed light from individual sector emissions. The circular sector design allows a small light-emitting zone suitable for small reflector lamps.

A versatile, flat-panel LED lighting fixture that integrates the driver circuitry and allows multiple LED configurations to be driven separately for redundancy. The fixture has a frame that houses an LED panel. The panel has LEDs along the edges and a power circuit board that converts AC to DC within the frame. The circuitry is narrow and fits in a channel in the frame. The fixture can alternate between LED configurations by driving sets of LEDs separately.

A high-power, energy-efficient lighting system for film and TV production that uses modular LED light sources. The system has a central hub connected to multiple radial modules. Each module contains an LED array, heat exchanger, and electronics. The modules extend radially and emit light through windows in a plane. This allows compact, modular construction with individual module replacement. An external frame connects the modules and hub. The modular design provides robust, lightweight, high-output lighting that can be expanded, replaced, or repaired easily.

Reducing the thickness of mobile devices by directly mounting protruding components like LED illumination and cameras inside the PCB. This is done by integrating PCB technologies to allow components to be mounted inside the PCB, reducing the Z height. Examples include PCBs with holes or apertures allowing components to protrude inside, or components with exposed connectors that can be soldered directly to the PCB.

Ultrathin LED light engine design with integrated heat dissipation, compact size and modularity for easy assembly. The light engine consists of a protective cover, a driving circuit board, an aluminum substrate, and LED modules. The circuit board is mounted on the aluminum substrate via a heat-conducting plate. The LED modules are mounted on the substrate and connect to the board with an insulated circuit. The cover reflects light and protects the components. The substrate and cover form a heat sink. This allows an ultrathin design with modular components while achieving good thermal management. The cover shape can be customized for different applications.

LED lighting device for automotive applications that provides improved light distribution and small dimensions compared to prior LED lamps. The device comprises at least two LED assemblies with LED elements mounted in a specific arrangement relative to each other. The LED elements are arranged along a rotation axis with their planes parallel to the axis. The LED assemblies are offset and rotated around the axis to achieve uniform light distribution. This compact configuration allows the LED device to replace traditional filament bulbs in automotive lamps while maintaining the regulatory tolerance box for filament placement.

Miniature adjustable linear LED lighting device with high color rendering index (CRI). The device has multiple LED filaments arranged inside a transparent outer container. The filaments are connected in parallel and emit light through a slot in an arc-shaped reflective housing. The device provides high CRI lighting in a compact form factor for applications like shop windows and shelves. The arc-shaped reflector creates a resonant cavity that repeatedly reflects the light back into the filament envelope to excite phosphors for better color rendering.
