pilveprožektor preferred
Usage examples
  • Pilveprožektori korpuse sees on kaks peeglit: esimene, hõõglambi kohal, peegeldab valgust allapoole teise peegli poole, mis seejärel peegeldab valgust ülespoole pilve, seejuures mõlemad peeglid on fokuseeritud, et tekitada suure intensiivsusega valgusvihk, mis muudab pilve põhja nähtavaks.
Good to know
  • Pilveprožektor on tavaliselt seatud 90° -le, kuigi maastiku suhtes võib kasutada ka kallet 71° 31' ja koosneb 430-vatisest hõõglambist, mis on seatud ilmastikukindlasse korpusesse.
ceiling projector preferred
Usage examples
  • Inside the housing of the ceiling projector are two mirrors; the first, above the bulb, reflects the light downwards to the second mirror, that then reflects the light upwards to the cloud. Both mirrors are focused to produce a high intensity beam of light that renders a visible spot on the base of the cloud.
Good to know
  • The ceiling projector is normally set at 90°, although 71° 31' may be used, in relation to the terrain, and consists of a 430-watt incandescent bulb set in a weatherproof housing.
