| Summary: | 碩士 === 國立成功大學 === 系統及船舶機電工程學系 === 107 === In this paper, we construct a color compensation module for underwater LED lighting, and propose a method based on the distance between the light source and the object to compensate for the loss of color of the object in the water. For module construction, we use 10 kinds of color LEDs to mix light, and adjust the mixed white light to simulate the illumination effect of sunlight, so that the color of water objects can be restored. Also, nine underwater light attenuation models of color light are also constructed. For the underwater light decay model, we use Beer-lambert law as the basis. Through the absorption coefficients of different wavelengths, we can obtain the underwater light decay curves of 9 kinds of color light by underwater light attenuation model. Finally, the underwater compensation curve of 9 kinds of color light is obtained through the underwater light attenuation curve of 9 kinds of color light, and the compensation results of 9 kinds of color light are realized by micro control unit. We use three kinds of light sources underwater to restore the color of the swatches, which are white LEDs, mixed white light and underwater LED color compensation lighting modules. The results show that the underwater LED color compensation lighting module is the most effective for the color reduction of swatches. This lighting can change the brightness of the distance to restore the color in the water.
