2. List of lighting design software - Wikipedia

   en.wikipedia.org/wiki/List_of_Lighting_Design...

   This is a list of lighting design software for use in analyzing photometrics, BIM (Building Information Modeling), and 3D modeling. The software is typically used by importing the structural design via CAD files. Then lighting elements are inserted. And finally, the lighting objects are associated with a photometry via IES files.

3. 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.

   en.wikipedia.org/wiki/Foot-lambert

   A foot-lambert or footlambert (fL, sometimes fl or ft-L) is a unit of luminance in United States customary units and some other unit systems. A foot-lambert equals 1/π or 0.3183 candela per square foot, or 3.426 candela per square meter (the corresponding SI unit).

5. Standard illuminant - Wikipedia

   en.wikipedia.org/wiki/Standard_illuminant

   CIE Publication 15:2018 introduces nine new illuminants representing several white LEDs with CCTs ranging from 2700~6600 K. [28] LED-B1 through B5 define standard LED illuminants with phosphor-converted blue light. LED-BH1 defines a blend of phosphor-converted blue and a red LED. LED-RGB1 defines the white light produced by a tricolor LED mix ...

6. Color temperature - Wikipedia

   en.wikipedia.org/wiki/Color_temperature

   For shooting with daylight film (calibrated to 5600 K) under warmer (low color temperature) light sources such as sunsets, candlelight or tungsten lighting, a bluish (e.g. #80A) filter may be used. More-subtle filters are needed to correct for the difference between, say 3200 K and 3400 K tungsten lamps or to correct for the slightly blue cast ...
