Aħna ppakkjajna dawn 680nm LED die vojt b'kaxxa SMD LED ta '3.5 * 2.8 * 1.9mm. Id-distribuzzjoni tal-wavelength ta 'kull wavelength ta' dawl f'dan ir-raġġ mhix neċessarjament simetrika mal-konfini tal-lambda λp . Dak li nħossu huwa r-riżultat komprensiv tal-azzjoni ta 'kull wavelength. Jikkorrispondi għal wavelength waħda ta 'dawl. Il-valur tal-wavelength huwa lambda λ D. Kif nafu, se jkun hemm xi simbolu li jidher fl-iskeda tad-dejta tal-LED: " λp " u " λ D ". Imbagħad x'inhu dak li jfisser? Normalment tara raġġ ta 'dawl, mhuwiex wavelength waħda ta' dawl, huwa magħmul minn taħlita ta 'ħafna wavelengths. L-enerġija tal-wavelength tad-dawl hija akbar minn dik ta' wavelengths oħra , allura dan il-wavelength huwa l-aqwa wavelength tar-raġġ. Fuq il-kurva tad-distribuzzjoni tal-wavelength, linja vertikali bejn l-axxisa u l-kurva taqsam iż-żona taħt il-kurva f'żewġ naħat ugwali. Il-valur tal-wavelength korrispondenti vertikali huwa lambda λ D.

*Luminous Intensity is measured by ZWL600.
*2q1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
*lD is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.
