In Part 1 of this two-part series, “Creating Uniform LED Luminescence in RGB Displays”, the discussion focused on dot correction. This design technique is used for managing individual pixel brightness ...

However LEDs are dimmed – be it by 1 – 10 V analogue voltage, mains phase angle, power-line, digital inputs such as DALI, or a WLAN link, there is in fact only two ways to actually dim the output of a ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...

KP1601X is a high efficiency Buck LED power switch designed for LED backlight. It adopts quasi-resonant control mode and integrates accurate zero-crossing detection of inductor current, which can work ...

To simplify incandescent-like LED dimming – where colour temperature (CCT) falls with intensity – Dialog Semi has introduced a single chip dual output power converter that needs no microcontroller.

Environmental Lights, the San Diego, Calif.-based, LED lighting solutions provider, has launched Dual-Mode Universal Dimming Drivers. Per the company, the Dual-Mode Universal (DMU) Dimming Drivers are ...
