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. Papaya contains the enzymes papain and chymopapain, which are similar to digestive enzymes. Papain is used in many commercial meat tenderizers because it helps break down proteins.
