Germany saves over 500 million euros in electricity costs with LED technology

Infineon announced that it offers the dp digital power 2.0™ platform. dp digital power 2.0 is a digital platform for power supply that enables the intelligent control of LED lighting systems to achieve maximum energy savings.

For every 5 kilowatt-hours, 1 kilowatt-hour is used for artificial lighting. However, using LED technology can save a lot of energy. In Germany alone, 13 million tons of _CO2 emissions could be saved, and electricity costs for German office buildings alone could be reduced by more than 500 million euros.

To transition to digital, which offers so many advantages, a digital controller is required, as well as specialized software that allows lighting system manufacturers to set individual variable values according to their design requirements.

Ulrich vom Bauer, Marketing Director for Lighting ICs at Infineon, said, “With the transition to digital, customers do not need to spend a lot of money developing new designs for various products every time.”

“Using .dp digital power 2.0 products allows us to reduce development time by up to 70 percent, enabling us to bring new products to market much faster,” he said. Digital techniques enable innovations that could not be realized using analog components.

The ICL8105 is a digitally configurable flyback controller with power factor correction (PFC) functionality, suitable for low-power LED driver applications ranging from 10W to 80W. This IC provides primary-side control, requiring only a small number of external components. This allows for a cost reduction of up to 10 percent. Additionally, this controller offers powerful algorithms and supports multiple operating modes.

In addition, it achieves high efficiency, excellent power factor correction (PFC), and low distortion. Thus, high-quality lighting can be achieved without flickering, and since this controller provides an input for 0V to 10V dimming, it does not require an oscillator. The dynamic burst mode significantly expands the dimming range and does not cause problems such as flickering or flickering. Finally, it automatically lowers the output current in case of overload to protect the LED driver from overheating.

Flexible application to various lighting using software

The ILD2111 is a digitally configurable buck controller designed as a constant current source using output current control (backlash) and is suitable for LED driver applications ranging from 10W to 150W. Therefore, it can be used in various types of commercial LED applications. The ILD2111 also requires only a small number of external components. The output current can be set simply and accurately using resistors, and it is compatible with the LEDset interface.

This IC provides flicker-free PWM dimming of less than 1 percent. It also automatically selects the appropriate operating window based on switching frequency and output current ripple to optimally adjust different loads. The output voltage ranges from 15V to 55VDC. Additionally, various user-configurable functions protect the IC from undervoltage, overvoltage, short circuits, overcurrents, and overheating.

These two ICs offer many of the advantages of digital techniques, including the ability to configure LED power supplies on-site using software. This high flexibility, as well as the ability to reduce material costs, is crucial in today's diversified lighting market.
