Dear all
I’m worked Luminance analysis.
but, I saw Rivero formula. so I have question.
According to Rivero formula varies transmittance of the incidence angle.
Therefore, it seems to change the reflectance&transmittance of the incidence angle.
[Rivero formula, T1 = 1.018T2(Cosθ+sin^3θcosθ), T1= transmittance of the incidence angleθ, T2= transmittance of the perpendicularly incident]
According to my results
- Simulation summary -
[Glass material from optics6(NFRC ID 6974+6957), transmittance 0.5022, Reflectance(front) 0.178]
[Date : June 21, 19:05 , Incidence angle[deg] : 83.244 ]
[Latitude(deg) : 37.225 , Longitude(deg) : 127.07]
[Sky : clear sky ( +s)]
- Simulation result-
Sun Luminance : 295,473,152 cd/m2
A spot Lumimance(Specular reflection) : 52,734,259 cd/m2 | B spot Luminance(Specular reflection) : 52,734,259 cd/m2
A spot/Sun : 0.1785 , B spot/Sun : 0.1785
This Reflectance ratio is similar of the glass material.
I did the simulation proceeds properly?
Is the angle of incidence of the light is applied?
Kind regards,
