Illumination of 150W high pressure sodium lamp
(for indoor or stadium lighting calculations)Use factor: general indoor take 0.4, sports take 0.3Maintenance factor: generally take 0.7 ~ 0.8For example: Muronai Terua: 4 x 5 meters room, use 3 x 36W grille lamp 9 sets,The average illumination light source = total luminous flux * CU * MF/ size = (2500 x 3 x 9 x 0.4 x 0.8) / 4 / 5 =1080 Lux
The calculation formula of illumination: the average illuminance (Eav) light source = total luminous flux (N* diameter) * utilization coefficient (CU) coefficient (MF) / * maintenance area (square meters)
What brand of sodium light? I sell the OSRAM brand as an example of ordinary 150W luminous flux 15000lm lamp, high efficiency lamp luminous flux 17500lm 150w. The specific illuminance needs to be calculated according to the actual situation.
