Patent ID: 10288227

Abstract:
A dimmable light emitting arrangement (100, 200, 300, 400) has a relatively low correlated color temperature in the dimmed state, and a relatively high and constant color rendering index. The dimmable light emitting arrangement (100, 200, 300, 400) comprises a first light source (10, 10a, 10b) adapted to emit light of a first wavelength range between 380 and 460 nm, a second light source (20, 20a, 20b) adapted to emit light of a second wavelength range between 570 and 610 nm, a first wavelength converting material (30), and a second wavelength converting material (40). The first wavelength converting material (30) receives light from the first light source (10, 10a, 10b) and converts light of the first wavelength range into light having an emission peak within a third wavelength range between 470 and 570 nm. The second wavelength converting material (40) receives light from the first and second light sources, and converts light of the first wavelength range and light the second wavelength range into light having an emission peak within a fourth wavelength range between 590 and 630 nm.
