  2. Standard illuminant - Wikipedia

    en.wikipedia.org/wiki/Standard_illuminant

    This is by design; the XYZ color matching functions are normalized such that their integrals over the visible spectrum are the same. [1] Illuminant E is not a black body, so it does not have a color temperature, but it can be approximated by a D series illuminant with a CCT of 5455 K. (Of the canonical illuminants, D 55 is the closest.)

  3. Color rendering index - Wikipedia

    en.wikipedia.org/wiki/Color_rendering_index

    R9 value, TCS 09, or in other words, the red color is the key color for many lighting applications, such as film and video lighting, textile printing, image printing, skin tone, medical lighting, and so on. Besides, many other objects which are not in red color, but actually consists of different colors including red color.

  4. Light-emitting diode physics - Wikipedia

    en.wikipedia.org/wiki/Light-emitting_diode_physics

    Colors that combine different wavelengths of light: Pink: Multiple wavelengths: ΔV ≈3.3 [27] Blue with one or two phosphor layers, yellow with red, orange or pink phosphor added afterwards, white with pink plastic, or white phosphors with pink pigment or dye over top. [28] Purple: Multiple wavelengths: 2.48 < ΔV < 3.7: Dual blue/red LEDs ...

  5. 3-way lamp - Wikipedia

    en.wikipedia.org/wiki/3-way_lamp

    A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage. Lamp bulbs with dual carbon filaments were ...

  6. Tritium radioluminescence - Wikipedia

    en.wikipedia.org/wiki/Tritium_radioluminescence

    Tritium is the only radiation source used in radioluminescent light sources today due to its low radiological toxicity and commercial availability. [3] Various preparations of the phosphor compound can be used to produce different colors of light. For example, doping zinc sulfide phosphor with different metals can change the emission wavelength ...

  7. Computer graphics lighting - Wikipedia

    en.wikipedia.org/wiki/Computer_graphics_lighting

    Computer graphics lighting is the collection of techniques used to simulate light in computer graphics scenes. While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity.

  8. Mogul lamp - Wikipedia

    en.wikipedia.org/wiki/Mogul_lamp

    Compact fluorescent mogul-base bulbs are also available, as are adaptors to allow medium-base bulbs to be used in mogul sockets. There are usually two three-way switches near the top of the floor lamp to operate the bulbs. One controls the three-way center bulb, and the other turns on one, two, or all three (or four) of the peripheral bulbs.

  9. Domain coloring - Wikipedia

    en.wikipedia.org/wiki/Domain_coloring

    Domain coloring plot of the function f(x) = ⁠ (x 2 − 1)(x − 2 − i) 2 / x 2 + 2 + 2i ⁠, using the structured color function described below.. In complex analysis, domain coloring or a color wheel graph is a technique for visualizing complex functions by assigning a color to each point of the complex plane.
