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 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.

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 …
