Standard light source box features: computer light touch button switch light source at will, the light box after power failure can automatically save all the record content; using yuan installed jin port SMD components, with the test function of the same colour and spectrum effect; display the use of each light source time and total time, record the name of the light source, the use of time and the number of times to switch; light source automatically switch, with the same colour and spectrum function, no heat (no heat dissipation), luminous No preheating, no flickering, fast and reliable colour evaluation; implementation of international standards: background colour and luminosity are very important when performing colour matching work.
As colour is a subjective perception, comparing colours against different backgrounds can produce different results. For this reason, all background colours are specified as medium grey and their reflectance must be less than one third of the incident light. The duration of use of each light source is recorded separately (it is recommended that the light tubes are replaced after 2,000 hours of use) to avoid detection errors caused by the ageing of the tubes.
Colour management in industrial production, although the quality inspector has carefully compared the colour of the goods, but because the ambient light source is not standard or inconsistent with the light source used by the customer, the colour seen under different light varies, and it is difficult to determine the colour difference of the goods. The customer will complain or even return the goods because the colour difference exceeds the standard range, thus seriously affecting the goodwill of the company.
To effectively solve the above problems, a useful method is to check the colour of the goods, must be in the same light source and can be controlled under the conditions. For example, the international standard often uses artificial light D65 as the standard light source to assess the colour of goods. Particularly important is the use of standard light sources to check the colour deviation of goods during the night shift. In addition to the D65 light source, the light box also provides light sources such as TL84, CWF, UV, F and A. The light box is equipped with the function of testing for homochromatic effects.
