Abstract A new scheme for the portable color temperature meter is proposed, which is based on the color temperature experience formula, using the selenium color sensors based on light-frequency conversion, the singlechip, digital circuit and software correction to control the system and calculate the color temperature. According to JJG212—2003, tests are performed. The results show that the technique specifications of the color temperature meter all meet or excel the requirements of JJG212—2003.
