Colour rendering Sample Clauses
Colour rendering. 4.1.1. Red content In addition to provisions as described in paragraph 4.16. of this Regulation. The minimum red content of the light of a LED module, when tested outside the device, shall be such that: 780 nm ∫Ee (λ) V(λ) dλ λ=610 nm 780 nm ∫Ee (λ) V(λ) dλ λ=380 nm ≥ 0.05 where: Ee(λ) (unit: W) is the spectral distribution of the irradiance; V(λ) (unit: 1) is the spectral luminous efficiency;
Colour rendering. 4.5.1. Red content In addition to measurements as described in paragraph 7. of part A or B to this Regulation, the minimum red content of the light of a LED module or light-generator shall be such that: kred = ∫ Ee (λ)V(λ) dλ λ =610 nm ∫ Ee (λ)V(λ) dλ λ =380 nm ≥ 0.05 where: Ee (λ) (unit: W) is the spectral distribution of the irradiance; V(λ) (unit: 1) is the spectral luminous efficiency; λ (unit: nm) is the wavelength. This value shall be calculated using intervals of one nanometre.
Colour rendering. For colour rendering, the hue angle of reproduced colour of the chart patches on the monitor shall satisfy the following requirements. The colour coordinates are described based in the CIE 1976 uniform colour space:
