Important points regarding drive methods and circuit configurations are published! Explained clearly using graphs and diagrams.
LEDs are current-driven light-emitting devices, and their characteristic values are specified with the forward current value as a parameter. Therefore, circuits that light up LEDs must be able to supply the necessary current to achieve the required brightness. Additionally, there are various driving methods and circuit configurations for lighting LEDs, each with its own advantages and disadvantages in achieving the desired characteristics. This document explains the points to consider regarding these driving methods and circuit configurations. We encourage you to read it.

Company information
Since its establishment in 1920, Stanley Electric has contributed to society by creating light. Applying the unique optical technology cultivated through the development of automotive headlamps, we entered the ultraviolet lamp market in 2010. We consistently develop from light sources to finished products to provide a safe and secure society through light for people around the world, and we will continue to develop deep ultraviolet light sources and their application products. We are also expanding our brand of sterilization products utilizing our ultraviolet technology, "AℓNUV." We supply ultraviolet devices that meet customer needs and expand applicable applications (air sterilization/surface sterilization/water sterilization), aiming to realize a daily life where everyone can live with peace of mind. Additionally, we have developed an infrared VCSEL device of automotive quality as a new sensing light source. We will add infrared VCSEL to our product lineup and provide suitable solutions to meet our customers' requests.
