Precautions for standard light sources

  1. Error range

  The key to the so-called standard light source is that this light source meets the requirements of the standard and must conform to the CIE standard of the International Institute of Illumination. Of course, the requirements of CIE are often a very wide range, such as the range of illuminance is as wide as 750Lux-3200Lux, and the color temperature range of some light sources is also allowed to have an error of ±500K.

The standards of some large enterprises are higher than the CIE standards, especially the standard light box manufacturers, which adopt more stringent production standards, such as controlling the color temperature range of the light source within ±200K to ensure that the light will be used for a period of time. Still within the scope of international standards.

  2, light source environment

  The inner wall environment of the standard light source box has a great influence on the standard light source. It must be a standard dark gray matt surface to ensure that it is not affected by the reflected light of the environment.

  3, light up quickly

  The standard light source cannot be turned on after flashing like some home or office lights. Fast and instant lighting is an important indicator of the standard light source box, and there can be no flicker after lighting, so as not to affect the light effect.

  4, the service life of the light

  The lights will age after being used for a period of time. In order to avoid system errors, the standard light source box is required to record the actual use time of each light source separately, and the upper limit of 2000 hours is not allowed.

  5, reduce operating errors and labor intensity

  The new sound-controlled standard light source box T-5 and T-6 with sound broadcasting function can issue the name of the light source in Chinese and English, avoiding the mistake of choosing the light source. At the same time, the operator can perform blind operations without leaving the observation object, which reduces the work intensity and ensures the effect of metamerism.
