Abstract: 本研究提出將以機構連桿設計概念做為裝置LED 載具,由機構曲柄
轉動角度控制RGB 三晶片光色混合比例,突破以往電壓電流單一色彩
限制的混光技術,希望在同一平面呈現多重色彩混色的效果變化。其主
要是利用四連桿機構驅動曲柄產生相對於固定連桿做等速全周完全旋轉
特色,並且將RGB 三顆LED 固定於四連桿機構中的耦桿上,經由耦桿
的傾斜角度變化來達到混光效果,再將耦桿上RGB 三LED 光源投射於
同一平面,藉由機構曲柄運轉,以求得三種光色的光路軌跡路徑,如此
可以確知RGB 三LED 光源在機構曲柄旋轉幾度的範圍內會進行光色重
疊進而達到三種光色的混光,且再經由曲柄的轉動來表示RGB 三色光
混合的比例由多至少,由少至多,因曲柄重複的旋轉,即可以在同一平
面呈現多彩混色的效果,最終製作模型驗證此創作設計之具可行性的。
A four-bar linkage design concept was proposed for LED carriers in this
study. The cranks rotated in different angles to control the mixing
proportion of RGB lights, which is a breakthrough compared to traditional
light mixing limited to only single colors controlled by voltage and current.
The design was intended to present the changing effects of mixing of
multiple colors on the same surface. The primary idea was to use the
four-bar linkage to drive the cranks and generate the 360-degree rotation at
constant speed relative to the ground link. Three LEDs in red, green and
blue (RGB) were installed on the coupl link in the four-bar linkage
mechanism. The light mixing was achieved by changing the inclination
angles of couple link. The lights emitted from RGB LEDs were projected
on the same surface. The cranks rotated to obtain the tracks of the three
beams of lights in different colors. This allowed the lights of RGB LEDs to
