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.
The history of electric light is well documented, [11] and with the developments in lighting technology the profession of lighting developed alongside it. The development of high-efficiency, low-cost fluorescent lamps led to a reliance on electric light and a uniform blanket approach to lighting, but the energy crisis of the 1970s required more design consideration and reinvigorated the use of ...
Floor plans use standard symbols to indicate features such as doors. This symbol shows the location of the door in a wall and which way the door opens. A floor plan is not a top view or bird's-eye view ; it is a measured drawing to scale of the layout of a floor in a building.
Light colored interiors and open floor plans are good choices. This approach also augments artificial light efficiency. Energy efficient lighting is not simply finding the most light for the least wattage or the longest lasting light bulb. Proper sizing of the light to the needs of the location and the tasks that will be performed, called task ...
Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
A fixture using replaceable light sources can also have its efficiency quoted as the percentage of light passed from the "bulb" to the surroundings. The more transparent the lighting fixtures are, the higher efficacy. Shading the light will normally decrease efficacy but increase the directionality and the visual comfort probability.

An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting . Lamps usually have a base made of ceramic , metal, glass, or plastic which secures the lamp in the socket of a light fixture , which is often called a "lamp" as well.
