Advancements in Standardization of LED Lighting Components

Calibrating device and method for adjusting luminance-chrominance of pixels near seams between adjacent LED panels to improve display quality in large LED displays. The calibration involves analyzing the seam region between panels, comparing the seam characteristics to a reference, and then adjusting pixel grayscale data near the seam based on the comparison. This compensates for variations in spacing and brightness due to the seam. The calibration uses modified luminance-chromaticity matrices that consider gain values near the seams.

Power plate assembly that simplifies modification and adjustment of lighting characteristics in commercial and residential lighting applications. The assembly includes a power plate assembly having a plate, a frame secured on the front face of the plate, and a power distribution circuit arranged on the rear face of the plate, wherein the power distribution circuit is configured to distribute electricity to a plurality of mounting locations defined by the frame on the front face of the plate.

A standardized modular LED lighting system that allows customizable and interchangeable lighting devices with different shapes, structures, types, and functions. The system uses standardized components like light-emitting modules, power supply connectors, and support systems that can be assembled in a building block fashion. This provides flexibility and configurability in LED lighting applications by enabling easy adaptation and modification of lighting devices using standardized components instead of proprietary and custom components.

Multi-LED system for devices like smartphones and cameras provides improved properties like better ESD protection and temperature monitoring. The multi-LED system has a carrier with a main body containing embedded electrical components like ESD protection and temperature sensors. The carrier has metallization layers on top and bottom for connecting the embedded components. The main body can be made of resin or polymer material. This integrated component packaging reduces space and improves reliability compared to separate components.

Adapting LED strips to fit into existing light fixtures without custom electronics. The goal is to leverage low-cost, standardized LED components like strips and drivers rather than custom LED bulbs. The adaptation involves physical forms and constraints that shape the LED strips to emit light in desired patterns when installed in fixtures. This allows using off-the-shelf LED strips and driver components while maintaining the look and function of traditional fixtures.

LED lighting provides uniform light output from multiple LED strings to prevent light emitting unevenness. The LED strings contain a series connection of ultraviolet or violet LED chips and blue LED chips. The number of UV/Violet chips is matched to the number of blue chips in each string. This balances the threshold voltages across strings to avoid current and brightness variations.

Designing an LED lighting fixture that allows the use of standardized, low-cost components like LED strips and drivers to create a complete lighting product. The fixture uses a physical form that shapes the LED strip into a desired emission pattern when attached. It also includes constraint mechanisms to hold the strip in place. This allows using off-the-shelf LED strips rather than custom electronics. A positioning form for the driver is also provided. The physical forms can adapt strips and drivers to fit inside existing fixtures.

Method and device for characterizing individual LEDs to enable grouping them in a desired manner to provide a desired overall light output from a lamp. The method involves measuring parameters like color, luminous flux, wavelength, spectral power distribution, and forward voltage of LEDs to characterize them. These measurements are stored and used to select LEDs for lamps based on desired light output specifications. This allows customized lamp lighting without using binned LEDs that have narrower parameter ranges.

A lighting system that allows the continued use of an energy-saving LED lighting source. The system includes at least one power source, at least one driver power module, the at least one driver power module including an input selector, at least one driver, an output selector, and a microcontroller, wherein the input selector is connected to an input of at least one driver and the output of the at least one driver is connected to the output selector; at least two light emitting diode light sources, the at least two light emitting diode light sources being connected in parallel to each other; wherein the power source is connected to an input of the input selector of the at least one driver power module, wherein an output of the output selector of the at least one driver power module is connected to an input of each of the at least two light emitting diode light sources, wherein each of the at least two light emitting diode light sources are connected to a lighting sensor, wherein the microcontroller communicates with the at least one lighting sensor.

Method for testing LED panels in high throughput without singulation by generating correction factors to compensate for re-emission of light from inactive LEDs around the device under test. The correction factors are determined using a reference LED on the panel and an integrating sphere. The correction map is generated once and used during testing to accurately measure the target LED's properties. This allows direct testing of the entire panel without handling each individual LED, improving yield and reducing contamination risk compared to post-singulation testing.

Controlled LED lighting module for fixtures that provides customizable lighting with fixed optics and standardized fixtures. The module has a compact LED light source with an elliptical light distribution. The light is contained by a pattern control optic inside the fixture housing. The optic shape and light source position relative to the housing create a specific beam pattern without needing to change the fixture shape. This allows customized lighting in standardized fixtures by swapping modules with different pattern control optics.

A converter for LED lighting systems that allows using interchangeable bulbs with different interface types in a system without requiring double inventory or pre-service inspections. The converter has two flanges with conductors passing through and around them to make electrical connections. One flange connects to the system's wedge interface and the other flange connects to the bi-pin interface of the bulb. This converts the bi-pin bulb to wedge interface compatible without stretching or bending the pins. The converter can be plugged into the wedge interface and the bi-pin bulb can directly connect to it, making an electrical connection through the converter.

A reusable high power LED module for lighting applications that allows field replacement of components like the LED chip instead of replacing the entire module. The module has a design that allows disassembly by hand to swap out components like the LED chip when it reaches end of life. This avoids wasteful complete module replacements. The module can still generate over 6000 lumens of light.

A set of LED emitters with varying lumen output that have identical physical dimensions. The emitters are arranged in a group where each emitter has a different number of LED chips, but they all have the same size mount. This allows using identical components for emitters with different lumen outputs, increasing parts commonality and reducing cost. The emitters have uniformly spaced LED chips covered by a casting compound to form a light field with discrete LED spots. The high fill level of the light field, where the area of the LED chips covers a large portion of the overall emitter area, provides a uniform appearance.

A standard illuminant apparatus for reliable and reproducible measurement of LED properties. The apparatus has two modules: an illuminant module to provide light and a light shape control module to adjust the light shape. The illuminant module can be a halogen lamp or an LED with temperature control. The light shape control module transforms the light to a predetermined shape like surface-mounted, lamp-type, array-type, or side-emitting. This allows providing standardized LED light with consistent properties for calibration and measurement.

LED lamp assembly that is designed to prevent disassembly and vandalism while avoiding the issues of separable lamps like accidental disconnection and the problems of inseparable lamps like high cost and yield loss from injection molding. The lamp has an annulus-shaped holder with openings at each end. The LED lamp is inserted through one end, wires connect the leads, and a plug seals the opening. The other end has a fixed cover. This allows separate fabrication and assembly of the components to prevent disassembly, while the plug and cover prevent removal.

Calibrating LEDs to achieve uniformity in light output and color across devices. The calibration involves measuring the LED output, comparing it to a reference value, and adjusting the LED output if needed. The calibration values are stored on the LED so they can generate consistent light output over time. This compensates for variations in LED bin sorting, aging, and temperature effects. The calibration can be done during manufacturing or in the field.

LED housing that can be easily extended in length by connecting multiple identical housings together, while also allowing detachable mechanical and electrical connection to other LED housing modules. The housing contains LED chips on a carrier element inside, with terminals on the outside for power and mechanical attachment. The detachable terminal and mechanical connections enable modular extension of the LED housing length by connecting additional identical housings. This allows scalability and flexibility in LED lighting systems by easily adding or removing modules.

Adjustable LED lighting fixture with independently aimable LED modules for targeted illumination. The fixture has a modular design with interchangeable LED housing that can be quickly replaced to customize the lighting output. The LED modules are mounted on blocks with adjustable pitch and height to aim the light beams independently. This allows focusing the light exactly where needed for different applications. The blocks also have sockets for electrical connection to the power source.
