Detailed Solution
Download Solution PDFIn illumination engineering, the Reduction Factor is defined as:
Mean Spherical Candle Power (MSCP): The average luminous intensity of a source in all directions.
Mean Hemispherical Candle Power (MHCP): The average luminous intensity over one hemisphere.
The reduction factor helps in determining how uniformly a light source emits in different directions.
Additional Information
- Maintenance factor: It is defined as the ratio of the illumination under normal working conditions to the illumination when the things are perfectly clean.
- Absorption Factor: It is related to how much light is absorbed by surfaces instead of being reflected.
- Utilisation Factor: It is the ratio of light reaching the working surface to the total light emitted.
