Waldenburg (Germany) – Würth Elektronik expands its range of WL-ICLEDs – RGB-LEDs with integrated controller (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 allow data transmission up to 13 times faster than with single-wire ICLEDs. The dual-wire ICLEDs offer precise control in LED applications that require individual color and brightness control, thereby significantly simplifying the wiring complexity. The integrated sleep mode makes them even more energy efficient.
These intelligent LEDs can be individually controlled in their pixel color across the full RGB spectrum and are digitally dimmable with 0 to 100 percent brightness levels – and all this with fast PWM rates of 20 kHz. This makes them ideal for high-speed animation and flicker-free display. Applications include industrial displays and HMI systems, full-color matrix displays, signal control systems, as well as smart and decorative lighting solutions, or gaming peripherals.
Würth Elektronik’s dual-wire ICLEDs not only allow precise control of LEDs, but also offer innovative features such as the integrated sleep mode that reduces current consumption to around 1 µA per ICLED when not in operation. This enables significantly more energy-efficient use, especially in battery-powered systems. In addition, the clock frequency of the data signal is freely adjustable up to 15 MHz 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 daisy chaining of multiple LEDs. They can be operated with supply voltages of 3.3 and 5.5 VDD. The components, available in 1616 (1.6 × 1.6 mm) and 5050 (5.0 × 5.0 mm) packages, feature the industry-standard footprint and can thus 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.
