Illumination engineering is a field that spans many topics, including the development of sources, design of luminaires and lightpipes, measurement of lighting conditions, and machine vision. … The two most common factors in illumination system design are efficiency and uniformity of the distribution.
What do Illuminating Engineers do?
1) Designs and directs installation of illuminating equipment and systems for buildings, plants, streets, stadia, tunnels, and outdoor displays: Studies lighting requirements of client to determine lighting equipment and arrangement of lamps that will provide optimum illumination with economy of installation and …
What is Illumination electrical engineering?
Illumination When light falls on a surface, it becomes visible, the phenomenon is called as illumination. It is defined as luminous flux falling on a surface per unit area. It is denoted by E and measured in lumen per square meter or meter‐ candle.
What does the illumination do?
The definition of an illumination is the act or process of making something clearer or brighter or a device for doing so. An example of an illumination is an explanation. An example of an illumination is a bright porch lamp. Spiritual or intellectual enlightenment.
How is illumination calculated?
Average illumination E = Flux required on the working plane / Area of the working plane E = Flux output by each lamp x No. of lamps x U.F. x D.F / Area STEPS OF LUMEN OR FLUX METHOD OF CALCULATIONS 1.
What is the illumination?
Illumination is defined as the energy of light (ε) striking a surface of specific unit area per unit time.

What are the types of illumination?
Types of Illumination
- Incandescence produces light by heating a substance.
- Electroluminescence produces light as a result of an electric current passed through a substance.
- Cathodoluminescence produces light as a result of being struck by an electron.
- Photoluminescence produces light as a result of absorption of photons.
What are the laws of illumination?
The law states that Illuminance at a point on a plane is proportional to the cosine of the angle of light incident (the angle between the direction of the incident light and the normal to the plane). It is the point source Illuminance equation.
What is illumination power?
Illuminating Power. The relative light given by any source compared with a standard light, and stated in terms of the same, as a burner giving an illuminating power of sixteen candles.
What does poor illumination mean?
Poor lighting can affect the quality of work, specifically in situation where precision is required, and overall productivity. Poor lighting can be a health hazard – too much or too little light strains eyes and may cause eye discomfort (burning, etc.) and headaches.
What is the biblical definition of illumination?
The most sumptuous works that they produced are now described as ‘illuminated’, meaning that they are enhanced by the application of gold or silver and painted or drawn decoration.
What is another word for illumination?

How do I calculate LED lights for a room?
To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.
What is the level of illumination called?
Light Level or Illuminance, is the amount of light measured in a plane surface (or the total luminous flux incident on a surface, per unit area). The work plane is where the most important tasks in the room or space are performed.
What does foot candle mean?
A foot-candle (or foot-candle, fc, lm/ft2, or ft-c) is a measurement of light intensity. One foot-candle is defined as enough light to saturate a one-foot square with one lumen of light. … Here are some typical foot-candle measurements for given light conditions: Unobstructed sunlight: 10,000 fc. Overcast sunlight: 100 …
