Diffusion control that realizes HSV dimming with a single chip.

A new dimming technology that allows colors to be determined by hue, saturation, and brightness.

"Diffusion control" is a technology that limits the lighting of RGB-LEDs to a single color through software control, allowing for quick switching to adjust the desired emission color. As a new initiative, it enables HSV dimming, which allows for easy natural color rendering by lowering saturation while maintaining hue, and brightness adjustments can change brightness while keeping the hue constant. Additionally, by inserting a complete RGB off at optimal timing, the dynamic effect maintains perceived brightness even with a slight reduction in brightness, achieving a very high energy-saving effect in conjunction with power efficiency that reduces the maximum supply current to one-third compared to conventional technologies. In PWM, where pulse width corresponds to light intensity, a short pulse width results in reduced resolution, and especially as the current value increases, excessive characteristics further complicate accurate color rendering. The diffusion control technology addresses these challenges. Since it synthesizes separated cone stimulation in the brain, it provides nearly unchanged color rendering for those with color vision deficiencies, which is well-received.
