Abstract

Keksintö kohdistuu menetelmään, jolla aikaansaadaan laajakaistaisen ja tasaisen tehokkaan LED-valon LED-valolähteellä, joka muodostuu useammasta LED:istä, jossa spektriä muokataan suodattamalla. LED:ien yhdessä tuottama valo + suodattimen/suodattimien yhteisvaikutuksella muodostetaan haluttu spektrijakauma.The invention relates to a method for producing broadband and uniformly efficient LED light with an LED light source consisting of multiple LEDs, in which the spectrum is modified by filtering. The light produced by the LEDs together + the combined effect of the filter(s) forms the desired spectral distribution.
