Precision dimming delivers simplified control over voltage, light output and color rendering Cree LED’s precision dimming is a new production technique that addresses unacceptable light output and hue variations when dimming parallel strings of LEDs to low current. These light output variations are caused by normal production variations in characteristics of LEDs and can be reduced substantially with proper system design. A novel production technique has been introduced to address the problems of inconsistent light output and hue experienced when dimming LED...
