Lighting and shadows

Lighting illuminates the performers and artists during a live theater, dance, or performing arts, and is chosen and organized to make dramatic effects. Stage lighting uses general illumination technology in devices organized for straightforward adjustment of their output characteristics. The setup of stage lighting is ready-made for every scene of every production. 

Dimmers, colored filters, reflectors, lenses, motorized or manually aimed lamps, and completely different sorts of flood and spot lights ar among the tools employed by a stage lighting designer to provide the specified effects. a group of lighting cues are ready so the lighting operator will management the lights in step with the performance; complicated theater lighting systems use laptop management of lighting instruments.

  Specification of illumination requirements for each given use area.

Light exposure

A demonstration of the effect of different kinds of lighting

In order to specifically live the number of sunshine coming into the attention, personal unit of time photometer referred to as the Days meter has been developed. This can be the primary device created to accurately live and characterize 
lightweight (intensity, spectrum, timing, and duration) coming into the attention that affects the human body's clock.
The small, head-mounted device measures somebody's daily rest and activity patterns, also as exposure to short-wavelength lightweight that stimulates the unit of time system. The device measures activity and lightweight along at regular time intervals and electronically stores and logs its in operation temperature. The Dosimeters will gather information for up to thirty days for analysis

Energy consumption

• Specification of illumination needs for every given use space.
• Analysis of lighting quality to make sure that adverse elements of lighting (for example, glare or incorrect color spectrum) don't seem to be biasing the planning.
• Integration of house designing and interior design (including selection of interior surfaces
   and area geometries) to lighting style.
• Design of your time of day use that doesn't expend surplus energy.
• Selection of fixture and lamp varieties that mirror best offered technology for energy conservation.
• Training of building occupants to use lighting instrumentation in best manner.
• Maintenance of lighting systems to reduce energy wastage.
• Use of natural light-weight

Lighting control systems

Low intensity lighting

Lighting management systems cut back energy usage and price by serving to produce lightweight only if and wherever
it's required.Lighting management systems generally incorporate the utilization of your time schedules, occupancy 
management, and electric eye management (i.e.daylight harvesting). Some systems additionally support demand response and can mechanically dim or put off lights to require advantage of utility incentives. Lighting 
management systems square measure generally
incorporated into larger building automation systems.
