Led array for disinfection comprising different types of leds

Abstract

The invention provides a radiation generating system (1000) comprising one or more first light sources (110) and one or more second light sources (120), wherein:—the one or more first light sources (110) and the one or more second light sources (120) are solid state light sources:—the one or more first light sources (110) are configured to generate in an operational mode first light source light (111) having a first centroid wavelength (λc1) defined within a wavelength range of at maximum 380 nm:—the one or more second light sources (120) are configured to generate in an operational mode second light source light (121) having a second centroid wavelength (λc2) defined within the wavelength range of at maximum 420 nm: wherein λc2>λc1:—the radiation generating system (1000) is configured to provide a beam of radiation (1001) comprising one or more of (i) a first beam (2111) comprising first light source light (111) having a first beam angle (α1) defined by full width half maxima and (ii) a second beam (2121) comprising second light source light (121) having a second beam angle (α2) defined by full width half maxima; wherein the first beam (2111) and the second beam (2121) at least partly overlap, and wherein α1<α2.
