LED lighting


The use of LED lighting, which is advantageous in terms of reducing power consumption and extending life, is starting to spread - thanks to a significant improvement in the performance of white LEDs in recent years. We provide a LED-dedicated driver that can control LEDs of up to four colors with each channel driven independently. Systems using stage or special lighting equipment can be easily developed using this driver.
Furthermore, our 8-bit microcontrollers for lighting purposes, which can perform dimmer control and operate in conjunction with networks, are ideal for highly functional lighting.
