The Effect of Wall Colors and Colors of Artificial Light from T8 LED Lamps on Generating of Electricity from Solar Cells
Abstract
This research is designed to study the color of artificial light and wall affecting the solar cells to generate power. For comparison, the colors of the artificial light from T8 LED lamp are Cool Daylight, Cool White and Warm White with the colors of wall are white, light yellow, light blue and black. To analyze about brightness and power from two types of solar cells that are mono and poly silicon. The trial has installed T8 LED lamp on ceiling of room size 1.9 x 1.4 x 2.5 cubic meters for artificial light source and installing solar panels at the bottom to convert light energy to electrical energy. Then, 100 Ohm resistance is loaded to measure electrical energy. The results shows that the color of the walls supports the light reflect. It makes more brightness. The White has the highest reflection coefficient followed by light yellow, light blue and black. And each color of light from LED T8 provides a different spectrum of light. It is affected for the solar cell to generate different power. Cool Daylight gives spectrum and light intensity more than Warm White and Cool white respectively, but the spectrum of each light is in the wavelength range for Solar cell in responding. The experiments use two kinds of solar cell by using same silicon crystals. So, both solar cells producing almost the same power under all conditions.
