Dual-wire RGB-LEDs easy to integrate and quick to react

Würth Elektronik has expanded its range of WL-ICLEDs – RGB-LEDs with IC – to include dual-wire ICLEDs. The components are addressable as pixels and consist of a red, green, and blue LED, as well as a pre-programmed IC in one package. They permit data transmission up to 13 times faster than with single-wire ICLEDs. The dual-wire ICLEDs deliver precise control in LED applications that need individual colour and brightness control, thereby greatly simplifying the wiring complexity. The integrated sleep mode makes them even more energy efficient.

These intelligent LEDs can be individually controlled in their pixel colour across the full RGB spectrum and are digitally dimmable with 0% to 100% brightness levels – and all this with fast PWM rates of 20kHz. This makes them excellent for high-speed animation and flicker-free display. Applications include industrial displays and HMI systems, full-colour matrix displays, signal control systems, and smart and decorative lighting solutions, or gaming peripherals.

The company's dual-wire ICLEDs not only enable precise control of LEDs but also supply innovative features such as the integrated sleep mode that lowers current consumption to around 1µA per ICLED when not in operation. This allows significantly more energy-efficient use, particularly in battery-powered systems. Also, the clock frequency of the data signal is freely adjustable up to 15MHz for flexible and fast data transmission. This combination of low power consumption and high adaptability makes the dual-wire ICLEDs particularly attractive for modern smart lighting applications.

The dual-wire ICLEDs support the daisy chaining of multiple LEDs. They can be operated with supply voltages of 3.3VDD and 5.5VDD. The components, available in 1616 (1.6mm × 1.6mm) and 5050 (5mm × 5mm) packages, provide the industry-standard footprint and can replace less advanced LEDs without changes to the layout. With an MSL3 rating, they have an ideal moisture-sensitivity threshold. Samples can now be ordered.
