2. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   The use of "turtle-safe lighting" LEDs that emit only at narrow portions of the visible spectrum is encouraged by conservancy groups in order to reduce harm. [131] Use in winter conditions: Since they do not give off much heat in comparison to incandescent lights, LED lights used for traffic control can have snow obscuring them, leading to ...

   en.wikipedia.org/wiki/Light-emitting_diode_physics

   LED development began with infrared and red devices made with gallium arsenide. Advances in materials science have enabled making devices with ever-shorter wavelengths, emitting light in a variety of colors. LEDs are usually built on an n-type substrate, with an electrode attached to the p-type layer deposited on its surface.

   en.wikipedia.org/wiki/LED_wallpaper

   LED wallpaper. LED wallpaper is the integration of light-emitting diodes into flat substrates suitable to be applied to walls for interior decoration purposes.. The experimentation on the combination of light sources and wall covering surfaces has been largely fostered by the progressive miniaturisation of low-voltage lighting technology, such as LEDs and OLEDs, suitable to be incorporated ...

   In 1969, Hewlett-Packard introduced the HP Model 5082-7000 Numeric Indicator, an early LED display and the first LED device to use integrated circuit technology. Its development was led by Howard C. Borden and Gerald P. Pighini at HP Associates and HP Labs , who had engaged in research and development (R&D) on practical LEDs between 1962 and ...
