Light-emitting diode therapy (LEDT) is an therapeutic approach using different wavelengths of LED lights to treat disease. (The diagram is a blue light therapy, 415 nm wavelength) Light-emitting diode therapy (LEDT) is a clinical approach that applies different wavelengths of light to cure diseases or conditions with skin-safe lights.
One-color light is well suited for traffic lights and signals, exit signs, emergency vehicle lighting, ships' navigation lights, and LED-based Christmas lights Because of their long life, fast switching times, and visibility in broad daylight due to their high output and focus, LEDs have been used in automotive brake lights and turn signals.
Harmonious was a multimedia, fireworks-based nighttime spectacular at EPCOT at Walt Disney World Resort in Bay Lake, Florida.Intended as the long-term replacement for IllumiNations: Reflections of Earth, Harmonious showcased and celebrated the cultures and stories of the world that have inspired various Disney films and music, and how it can unite us all, overcoming any language or border.

LED lights can be designed to mimic the patterns of scales on fireflies' abdomens, improving their efficiency. [112] Morpho butterfly wings are structurally coloured to produce a vibrant blue that does not vary with angle. [113] This effect can be mimicked by a variety of technologies. [114]
Pressure level probes are submerged directly into the liquid and remain permanently floating above the tank bottom. The measurement is carried out according to the hydrostatic principle. The gravity pressure of the liquid column causes an expansion of the pressure-sensitive sensor element, which converts the measured pressure into an electrical ...
MicroLED light panels are also being made, and are an alternative to conventional OLED and LED light panels. [71] Digital pulse-width modulation is well-suited to driving microLED displays. MicroLEDs experience a color shift as the current magnitude changes. Analog schemes change current to change brightness.
