LED lights have already replaced most consumption significantly. These sensors have to meet installations fitted with either inefficient light sources like more stringent demands than the current passive infrared incandescent lamps or even more efficient sources like sensors that can only detect very rough motion. HID lamps designed for extended operating hours. LED penetration has been incredibly rapid across applications Another topic that is gaining more attention is the such as tunnel and subway lighting and outdoor lighting. efficiency and dimming quality of LED drivers. Today, most users are happy with an efficiency rate of 88 percent for Looking ahead, we will focus on: power conversion. However, this figure could be easily › High-power LED lighting, for instance in stadiums pushed far above 90 percent by changing the topology for › Horticultural lighting to replace 1000 W HPS lamps power conversion. › Office lighting to replace fluorescent lamps Dimming is currently widely deployed in residential Many may assume that these developments mark the and hospitality lighting applications. Street lighting end of the LED innovation journey. However, here at applications do not typically support dimming Infineon Technologies, we anticipate significant new functionality. LED dimming can enable substantial power momentum in the LED space – and we are set to help savings compared with previous light sources and extend shape future developments. the system’s lifetime. All indicators show that current efforts are not sufficient to At Infineon Technologies, we are passionate about slow down global warming. Today, many LED installations developing these exciting applications in collaboration are not equipped with any control technology. Many users with our customers and partners. Our ambition is to offer are satisfied with the energy savings they have achieved customized products and solutions to our customers to thus far by converting their existing light sources to LEDs. address the critical energy efficiency challenges facing However, looking to the future is set to change – driven by society now and in the future. direct or indirect regulatory requirements and the resulting increase in taxes on energy consumption and CO emissions.

The trend is topology and the type of components used. A resonant now moving towards more elegant methods with LED topology, for instance, can increase LED driver efficiency by driver manufacturers and lighting fixture makers opting 4–5 percent. The right MOSFETs, a high-voltage start-up for NFC technology, for example. Digital controllers with cell and synchronous rectification can also have a positive a digital interface such as UART enable designers to impact. Dimming down to 1 percent light output has implement power monitoring at luminaire level. become mainstream for indoor lighting . www.infineon.com/leddrivers 55 LED drivers Mixed-signal PFC and flyback controllers ICL8800*/ ICL8810*/ ICL8820* ICL88xx family of single-stage flyback controllers for constant voltage output is tailored for LED lighting applications to meet the required performance cost-effectively. They offer benchmarking performance for power factor correction and total harmonic distortion at full-load as well as at low-load conditions. Also, the controller’s low standby power provides more margin for smart lighting systems that contain microcontrollers. The jitter function enables fulfillment of EMI requirements when the luminaire is foreseen to operate as an emergency luminaire.

Solutions with start-up resistors consume power not only during the IC‘s start-up also throughout the entire operation.In most implementations where the depletion-mode MOSFET is used, these are switched off after start-up. Features Benefits › Normally-on device › Enables fast time-to-light < 500 ms › Can be switched off after start-up › Higher system efficiency than start up resistor solutions › Requires very few external components › Increased system reliability due to lower thermal load › Small SOT-23 package › Helps fulfilling low system stand-by power requirements < 500 mW Start-up current source An external HV cell is preferred, e.g., designs with low standby power and no standby power. With a depletion MOSFET, even at V =0 V current will flow through the device. For a depletion MOSFET, a negative V has GS GS to be applied to turn it off.
