   Mood lighting is igniting or illumination, ... performance, and sleep quality in comparison to lighting with a lower color temperature. ...

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.

   A 230-volt LED filament lamp, with an E27 base. The filaments are visible as the eight yellow vertical lines. An assortment of LED lamps commercially available in 2010: floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications An 80W Chips on board (COB) LED module from an industrial light luminaire, thermally ...

   However, all negative effects to orange were neutralized when orange store color was paired with soft lighting. This shows that store color and lighting actually interact. [57] In this research, participants were not actually exposed to different colors of stores, but instead, color and lights were manipulated through the written description of ...

6. Color temperature - Wikipedia

   en.wikipedia.org/wiki/Color_temperature

   Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.

7. Light-emitting diode physics - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode_physics

   The wavelength of the light emitted is a function of the band gap of the semiconductor material used; materials such as gallium arsenide, and others, with various trace doping elements, are used to produce different colors of light. Another type of LED uses a quantum dot which can have its properties and wavelength adjusted by its size. Light ...
