With the use of the LED is becoming increasingly popular, more and more diverse applications, the business opportunities of which the intelligent lighting system by the industry expectations. To build the LED Smart lighting systems, import MCU to automatically adjust the brightness, colors automatically change, environmental sensing, and the group system control functions, rich LED lighting applications, and improve energy efficiency.
Zhu short Sen, senior applications engineer in Infineon, the MCU allows the LED lamps and intelligent lighting system, fully improve the efficiency of energy use and rich multi-LED applications.
Lack of control and change the LED lamps in the past, even if the LED than traditional halogen, incandescent and more durable, but prolonged use, the LED light output will be aging and temperature effects and recession, resulting in electric lighting device easy damaged, so that substantially reduce the reliability of, and can not be dimming defects caused by energy use inefficient Taking all these factors ultimately caused the LED shorten the life of, at the same time applications, also because of the light can not change even more tedious.
Zhu short Sen further pointed out that, in order to achieve dimming control, color transform the goal of efficient use of energy, LED lighting into the MCU to indoor lighting, outdoor lighting, decorative lighting, emergency lighting application changes, such as control of the LED lights in the day, according to each different time periods to adjust the brightness to save energy, or through the MCU in the digital addressable lighting interface (DALI) control group remotely and to monitor the LED device is still normal operation, to facilitate the notification engineers to quickly repair, these new applications for LED lights is no longer only just opened and shut it, but also more flexible use.
, Infineon seize LED smart lighting market territory, introducing the XC835 XC836 two MCUs, this two MCU In addition to the pin number and size, the biggest difference is the XC836 supports DALI, LED lamps do intelligence system of the remote control, the XC835 is not supported. In addition, the two will be supported by touch control, and both have a high heat (150 ° C) and high reliability characteristics. At present, the series MCUs are mainly used in entertainment decorative lighting market small and medium-sized T4, T8 fluorescent tube and bulb lights.
Entertainment decorative lighting market, entertaining performances were colorful, not only attach importance to the wisdom of an auto-dimming, the service life of LED lighting, luminous efficiency and light stability requirements, so the adjustable optical drive to solve the above The problems began to be designed in the lighting system.
