第15回 「TLC5940で16個のLEDを遊ぶ」 多数のLEDを手軽に光らせたいと思ったことはありませんか? 我々はたびたびそう思います。そんなときに使うのがArduinoとTLC5940です。 TLC5940はテキサスインスツルメンツのLEDドライバICで、1チップで最大16個のLEDを制御できます ...

Abstract: In this paper, one AC light-emitting diode (LED) driver with high power factor (PF) and low total harmonic distortion (THD) is adopted, which is added with the proposed switched LED module ...

Abstract: Direct AC LED drivers have advantages over conventional LED drivers in size and cost because of no need for bulky and expensive inductive components. However, none of conventional direct AC ...

AC LED driver circuits are overly popular due to the advancement of High current white LEDs. We already made a Transformerless LED driver circuit previously, but in that circuit, we used a dedicated ...

At the Strategies in Light Europe conference, Texas Instruments Incorporated introduced two highly integrated, phase-dimmable AC/DC LED lighting drivers, LM3448 and TPS92070, for use in solid state ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...
