Making dimming profile

[Niki2001]

Could you please tell me for making a dimming profile, where I must insert numbers( e1, 50, 1, 500 ,0.2 ) in the APpro
profile database?

Hi,

I think this is also covered elsewhere but there is a good example in the ApPro user guide on page 34 http://www.iesve.com/downloads/help/ve2 ... /APPro.pdf

ramp(e1,0,1,500,.4) a formula suitable for applying as a dimming profile controlling lighting gain as a function of available daylight. It modulates the lighting gain as a function of the illuminance on the working plane, e1. The value of the profile falls from 1 at zero illuminance to 0.4 at illuminance 500 lux, thereafter remaining constant at this value. The value 0.4 (which you should set as appropriate) represents the fraction of the room‟s lighting gain which is not subject to daylight control. The illuminance e1 must be computed using the link to Radiance.
