In lighting design, the lumen method, (also called zonal cavity method), is a simplified method to calculate the light level in a room.The method is a series of calculations that uses horizontal illuminance criteria to establish a uniform luminaire layout in a space.
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 ...
In addition to the light plot there are a number of other important pieces of paperwork (i.e. dimmer hookup, instrument schedule, and magic sheet) in a complete lighting design. As each part of the lighting design is relevant only to a specific group of technicians, the entire design is generally provided only to the director and master ...
Oak Ridge National Laboratory (ORNL) has developed a new alternative to skylights called hybrid solar lighting. This design uses a roof-mounted light collector, large-diameter optical fiber, and modified efficient fluorescent lighting fixtures that have transparent rods connected to the optical fiber cables. Essentially no electricity is needed ...
A lighting designer can provide specific recommendations for lighting in a home. The layout of lighting in the home must consider control of lighting since this affects the wiring. For example, multiway switching is useful for corridors and stairwells so that a light can be turned on and off from two locations. Outdoor yard lighting, and ...
In a light commercial environment, more frequent wiring changes can be expected, large apparatus may be installed and special conditions of heat or moisture may apply. Heavy industries have more demanding wiring requirements, such as very large currents and higher voltages, frequent changes of equipment layout, corrosive, or wet or explosive ...
In theatrical productions, an instrument schedule is a listing of all the lighting instruments and information about them used in a show. [1]: 223 The instruments are organized by their position on-stage, and is the distinguishing characteristic between an instrument schedule and a channel hookup or similar paperwork. The instrument schedule ...
The lighting designer enters the light plot into the visualization software and then enters the ground plan of the theater and set design, giving as much three-dimensional data as possible (which helps in creating complete renderings). This creates a 3D model in computer space that can be lit and manipulated.
