This document summarizes the key aspects of illumination and its effects. It discusses illumination as both a science and art that involves measuring lighting parameters and designing efficient systems. Adequate lighting is important for industrial task efficiency. The objectives of a good lighting system are to provide sufficient, uniform light distribution over work areas to fulfill functional, aesthetic, and economic needs. Insufficient, glaring, poorly distributed, or over illumination can cause issues like headaches, eyestrain, and decreased productivity and performance. Proper lighting design aims to avoid these negative effects.

2. ILLUMINATION
 Is brighten by light
 It is both science and art.
 The scientific aspects include the measurement of
various lighting parameters and the design of energy
efficient system.
 The artistic side comes into play in combining light
source.

3. NEED FOR ILLUMINATION
 The majority of industrial tasks will depend for their
efficiency on adequate vision, and therefore lightning
plays an important part in determining the efficiency
with which tasks are carried out.
 it is usually defined in terms of lumens per square
foot(lm/ft)

4.  It should fulfill aesthetic, emotional, as well as
economic and functional requirements.
 The main objectives of any good lightening
system are to provide adequate illumination with
uniform light distribution all over the working
plane.
 A well designed illumination system adds to the
productivity of its occupant, creates a lively
atmosphere and reduces fatigue.
OBJECTIVES:-

5. EFFECTS
 Insufficient light-not enough light as per the need
 Glare-too much light for the need
 Improper contrast
 Poorly distribution of light
 Thermal heating

6. Over Illumination
 Presence of light which is higher
 Causes - Illuminating an unoccupied area
 Using electrical lights instead of natural light
 Over-illumination has been linked
to headaches, fatigue, medically defined stress,
anxiety, and decreases in sexual function
 Energy and economic consideration

7.  Low productivity
 High human error rates
 Inability to match or select correct colors
 Eyestrain
 Headache
 Low employee morale
 Rapid fatigue
EFFECTS ON PERFORMANCE:-
