    Abstract: The invention relates to a light source (1) comprising at least one light emitting device (2) capable of emitting electromagnetic radiation in the range from near ultraviolet to blue in response to a driving signal of a driving means (6). A luminescent cover (3) comprises at least a first activator (A 1 ) and a second activator (A 2 ) to convert said electromagnetic radiation into visible light. The first activator and second activator have different response characteristics and the driving means (6) is adapted to vary said driving signal to control the spectrum of said visible light for said light source. Preferably, the driving signal is a pulsed driving signal and said driving means is adapted to vary the pulse width of said pulsed driving signal. Accordingly, the light source (1) has a dimming performance resembling that of an incandescent lamp.
