Measurement of Emission Spectra of LED Light Bulbs

Light sources that emit visible light, such as fluorescent lamps and LED light bulbs, have specific emission spectra. The hue of the light emitted by these light sources is determined by what extent to which different wavelengths of light are emitted. When a light source such as a light bulb is developed, measuring the emission spectra of the light source is very important for examining what kind of light the light source emits. Emission spectra are usually measured with a UV-visible spectrophotometer (UV) or a spectrofluorophotometer (RF). When a UV instrument is used, the emission spectra that are measured incorporate some characteristics of the measurement instrument (instrument function), and are different spectra to those actually observed by a person. Shimadzu's RF-6000 spectrofluorophotometer system includes a function that automatically removes this instrument function (an automatic spectrum correction function).
Therefore, using the RF-6000 allows for acquisition of accurate emission spectra that are not affected by the instrument function.
