Right Answer is:
Indirect lighting
SOLUTION
Indirect lighting Scheme:
- In this light scheme, more than 90 percent of total light flux is thrown upwards to the ceiling for diffuse reflection by using inverted or bowl reflectors.
- In this scheme, the ceiling acts as the lighting source, and glare is reduced to a minimum.
- It produces shadowless illumination, which is very useful for drawing offices and in workshops where large machines and other difficulties would cause troublesome shadows if direct lighting schemes were used.
