Color Mixing Apparatus

Grade 12.

A compact, economical, and effective three-color light projector that uses three low-voltage, high-power LEDs to project easily-seen red, green, and blue light onto a white screen. The projector mounting allows the beam angles to be adjusted to vary the overlap of the three colored images. The intensity of each LED can be adjusted separately by a potentiometer to give a convincing white light or various shades of mixed colors. Colored shadows can also be explored in a darkened room. Projector measures 8-3/4 in. H x 6-3/4 in. W x 6-1/3 in. L. White screen is 5-1/2 in. W x 3-1/2 in. H and stands 7-1/2 in. tall. Includes wall mount, power supply, and manual.
