By locating red, green and blue LEDs adjacent to one another, and properly mixing the amount of their output (Zhao et al. 2002), the resulting light is white in appearance. 1  Figure 4. Spectral power distributions of several types of LEDs. 2  Figure 5. Spectral power distributions of early phosphor-based white LEDs (left), and white LEDs using more recently developed phosphors (right) with increased output between 600 and 650 nanometers.
Home Remedy for Upset Stomach #3 â Papaya. Papaya fruit or papaya enzyme capsules are both effective at assisting with digestion.
