Abstract
A necessity for cheaper but more effective stage lighting motivated the researchers to think about using single white light source as alternative to multi-color spotlights. The researchers made a low-cost simplified prototype design that was energy-saving. The bulb was placed on a synchronous motor and rotated 360 degrees. The rotation was operated by the use of the switch. It was manipulated so that the single white light bulb would focus only to a particular glass covered with colored cellophane and produced a colored light that will be reflected to the stage or reflecting surface with the use of a plane mirror. The researchers constructed three prototype designs; the simplified prototype design that functioned with a switch, the computer-programmed design that used a program in the computer Turbo-C instead of switch, and the manually-operated design which neither used a switch nor any program. There was a significant difference between the experimental and control set-ups. The simplified prototype design was way more effective in stage lighting as compared to the traditional multi-color spotlighting in terms of cost and electrical energy consumption. The first prototype was found to be the most effective alternative to traditional spotlight; it was economical and easy to manipulate. Second was the programmed design, because it was easy to manipulate, yet the most expensive among the three prototype designs. Last of all was the manually-operated design which was disadvantageous as it had to be directed to the outlet, although it was the most inexpensive. The study proved that a single white light source can be an alternative to multiple colored lights in a simplified prototype design for effective stage lighting, so there is no reason not to further improve the aforementioned study for practical use.
