LIGHT SOURCE |
摘要 |
The invention relates to a light source for generating light having a spectral emittance in at least a part of the range of 380 nm to 680 nm. The light has a spectral power distribution E(λ) as a function of the wave-length λ over a first range of 600 nm<=λ<=680 nm, a second range of 505 nm<=λ<=600 nm, and a third range of 380 nm<=λ<=505 nm. A first ratio of the integral power distribution over said first range to that of a range of 380 nm<=λ<=680 nm is given by the relation: Formula (I) wherein 0.65<=Pl<=0.95, A second ratio of the integral power distribution over said second range to that of a range of 380 nm<=λ<=680 nm is given by the relation: Formula (II) wherein Pm>=0.08, A third ratio of the integral power distribution over said third range to that of a range of 380 nm<=λ<=680 nm is given by the relation: Formula (III) wherein Ps>=0.03 or Ps>=0.015 if Pl>=0.75l A respective radiation emission peak in each of the first, second and third wavelength range has a full width half maximum (=FWHM) of at least 12 nm. |
