Countries around the world are working to reduce CO2 and other greenhouse gas emissions in the fight against global warming, and there is an increasing movement towards energy reduction and use of renewable energy worldwide aimed at the realization of a post carbon society.
Compared to conventional light sources, LED lighting consumes less energy, is longer lasting, more compact, and more lightweight, but concerns regarding global warming and environmental impact are driving demand for even greater reduction of energy consumption and longer usable life. This has in turn resulted in even greater demand for reduction in size and higher efficiency in the power semiconductors which are key parts of LED lighting devices.
In order to respond to market needs, our company offers a diverse range of power semiconductors from bridge diodes to power MOSFET and LED drive IC, and PFC circuit devices for compatibility with harmonic control※ in order to contribute to energy saving and longer usable life in devices.
※ What is harmonic control?
In alternating current the basic frequency voltage is called the fundamental waveform and high frequency components other than the fundamental waveform which distort the waveform are called harmonics. Harmonics cause abnormal noise, vibration, burnout, and other problems in devices. Harmonic control is the categorization of the harmonics generated by electronic devices into classes A through D to stipulate the harmonic generation limits of the devices. These are applied to LED lighting for devices with an input power of 5W or higher.
