Advanced Components for LED Lighting Integration

A removable control module for LED modules that allows flexible and easy adaptation of LED lighting systems to work with different LED module types without needing to replace the whole system or reconfigure the driver. The module can be detachably attached to an LED module to provide control and power to the LEDs. This allows a new module to be used without modifying the driver. The control module contains electronics to regulate current and dimming for the LEDs. The LED module itself has connections for attaching the control module. By swapping out control modules, lighting systems can be adapted to work with different LED modules without replacing the entire system or modifying the driver.

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.

Controlling multiple LED fixtures to match their output even if they have different LEDs, by using a reference fixture and normalizing inputs. Each fixture receives the same direct drive signal, but instead of using it directly, they calculate the output of the reference fixture from the input. Then they find the drive values for their own channels to match that reference output. This allows consistent lighting from multiple fixtures despite LED variations.
