  • System of assessing performance of a photocuring light source for a printing machine and a combination having same
    Patent number: 11225098
    Abstract: A system of assessing performance of a photocuring light source includes a photocuring light source unit, a light source control unit, a sensing unit, and a computer unit. The light source unit produces light rays on a work platform of a printing machine. The light source control unit is electrically coupled to and controls the light source unit. The sensing unit is disposed proximally to the light source unit to detect power of the light rays from the light source unit. The computer unit is electrically coupled to the sensing unit and the light source control unit to control the light source unit and record the power of the light rays and operating period of the light source unit. A combination having the system is also disclosed.
