In this edition of the LED Lighting News, OSRAM Opto Semiconductors explores monochromatic LEDs. Monochromatic LEDs emit a single color or wavelength of light, making them optimal for unique applications such as plant growth, algae growth, animal environments and aquarium lighting. They can even help solve a longstanding problem facing sea turtles: outdoor lighting can disorient hatchling sea turtles who are drawn to the bright light of the sun or moon. By using special LED colors that exclude blue wavelengths in street lamps, “turtle-safe lighting” can be used to light the way to the ocean along beaches. These are only a few of the many new and exciting ways monochromatic LEDS can be used to improve and optimize the quality of light in emerging fields of lighting.
