LED tube parameter test requirements and methods

3. Spectrophotometer

The spectrophotometer is used to measure the spectral reflectance. Its optical principle is the same as that of a spectroradiometer.

The light emitted by the corresponding light source is dispersed and then directly projected onto the sample or white standard surface. This is done by putting

The dispersive beam is divided into two parts, or the dispersive beam is refracted alternately on two surfaces. From

The ratio of readings can calculate the reflectance of each wavelength in the entire spectral range.

If the material being measured scatters light, it is necessary to use a small integrating sphere to collect the reflected light. Spectrophotometer also

It can be used to measure the large spectral transmittance of materials. When irradiated with a standard light source, measure the spectral transmission of the material

The chromaticity of the transparent material can be determined by calculating its chromaticity. Publications in the International Commission on Illumination

In (CIE, 1977c), the ideal lighting and geometric conditions for collecting light in spectrophotometry are discussed.

4. Illuminance meter

The illuminance meter is usually composed of a photocell with a wire and an electric meter used to read the illuminance. It can be used directly for lighting

Take measurements on site. A simple illuminance meter can use a selenium photovoltaic cell, and a high-precision illuminance meter can use a silicon photovoltaic cell.
