| Mechanism-driven color mixing | Electronically controlled color mixing |
|
| A four-bar mechanism is used as the carrier; RGB LEDs are mounted on the couple links of the mechanism; the rotation of cranks is used for color mixing simulation. | Inputs of voltage and current are used to project light on different lenses, and the color mixing effect can be enhanced with reflection and refraction. Multiple lenses are required to achieve color mixing effect. |
|
| The rotation angle of cranks and the inclining angle of couple links are adjusted to perform mixing of the three colors of RGB. | The quantity of voltage and current inputted is used to control how much the RGB colors are mixed. |
|
| The colors projected on the same surface have direct single colors and area of multiple gradual colors. | There can be a large number of color changes, but at the end, the colors projected on the surface are single colors. |
|
| The range of lighting is wide; that is, the color mixing can be projected over a large area, as the cranks rotate 360° in the mechanism. | The lighting range is limited to a certain degree. |
|
| Due to wide range of lighting, the combination with LED lights of greater lumens may increase the projection distance. The mechanism style color mixing is that the LEDs of three different colors are mounted on the mechanism independently and create mixing that is independent of one another. This allows the users to adjust the lighting directions of the three mechanisms to achieve mixing of specific colors. | Electronic color mixing works by packaging the LEDs of three colors on one chip. Due to this limit, the light color may not be easily focused as the projection distance increases, thus the light dispersion. |
|
| As the three mechanisms rotate at the same time, the entire color mixing mechanism is large in size and requires large space for the operation. | The electronically controlled color mixing devices are smaller in size. |
