2. Super-LumiNova - Wikipedia

   en.wikipedia.org/wiki/Super-LumiNova

   Electrons within the pigment are being "excited" by ultraviolet light exposure—the excitation wavelengths for strontium aluminate range from 200 to 450 nm electromagnetic radiation—to a higher energetic state and after the excitation source is removed, fall back to their normal energetic state by releasing the energy loss as visible light ...

3. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   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.

4. SMD LED - Wikipedia

   en.wikipedia.org/wiki/SMD_LED

   The light from white LED lamps and LED strip lights is usually provided by industry standard surface-mounted device LEDs (SMD LEDs). [2] Non-SMD types of LED lighting also exist, such as COB (chip on board) and MCOB (multi-COB). Surface-mounted device LED modules are described by the dimensions of the LED package. A single multicolor module may ...

5. LED circuit - Wikipedia

   en.wikipedia.org/wiki/LED_circuit

   Simple LED (Light Emitting Diode) circuit diagram. In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.

7. Light-emitting diode physics - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode_physics

   Instead of increasing current levels, luminance is usually increased by combining multiple LEDs in one bulb. Solving the problem of efficiency droop would mean that household LED light bulbs would need fewer LEDs, which would significantly reduce costs. Researchers at the U.S. Naval Research Laboratory have found a way to lessen the efficiency ...
