Application of the Mechanism Design to Develop the RGB LEDs Color Mixing

Abstract

The big advantage of LED is the flexible spectral design to make white light using different color mixing schemes. Recently, the color mixing of RGB LEDs is mostly done by sealing all three chips at single package and regulated the mix ratio of these three colors to produce the color of light. And, by changing the LEDs array alignment, RGB chips can achieve overlapping colors of light and create the fun of changing colors in light mixing. Therefore, the purpose of this study is to propose an innovative technique of light mixing. By applying the mechanism design, a RGB light mixing mechanism is produced. Each of the RGB LEDs lamp-type is installed on the couple link of the three mechanisms, respectively. By driving a crank makes the couple link and an output link to produce the relative motion, this will result in the fact that the RGB lamps can project lights on the same plane in order to obtain the color mixing. Unlike mixing technique by control system, this design generates light mixing and changes of color with the synchronized driving of three mechanisms, thus achieving the dazzling perception of single-color lights or mixing of multiple colors for creating ambience of a space.

Tricolor R/G/B Laser Diode Based Eye-Safe White Lighting Communication Beyond 8 Gbit/s

“…In 2010, Wang et al reported the use of a novel control system to flexibly change the light color and luminous intensity of RGB-LED rendered white light 12 . In 2015, Hung et al preliminarily constructed an RGB LED-based white light with multicolor rendered output by rotating the controllable mechanism 13 . To meet the data transmission demand, RGB LEDs within the white-lighting module were used to construct a wavelength-division multiplexing (WDM) VLC link.…”

The Application of the Design of the Experiment to Investigate the Stability of Special Equipment

“…Monte Carlo simulations reveal that the D-optimal design is more accurate and precise than current experiment design approaches. Hung and his co-workers [19] presented a novel method for combining light. An RGB light-mixing mechanism is made by applying the mechanism's design.…”
