Abstract

The invention relates to the technical field of photo-curing, in particular to an optical mechanism for offset printing light curing. The optical mechanism comprises a shell, a heat dissipation device, a light source assembly and a first optical lens, wherein the heat dissipation device is arranged in the shell, the light source assembly comprises LED lamp beads and a first substrate for bearing the LED lamp beads, the first optical lens is arranged right front of the LED lamp bead, so that light rays emitted by the LED lamp beads are converged; the heat dissipation device is propped against the substrate, and the LED lamp beads comprise a plurality of chips. A quartz glass sheet or a cylindrical quartz glass rod of a flat plate adopted by a traditional UV-LED light source is changed intoa special-shaped quartz glass, the LED lamp beads packaged in the 16 PCS purple light chips are combined and closely arranged, so that the light source UV energy and the optical power density are greatly improved, the light curing effect and the production efficiency are improved.

Description

technical field [0001] The invention relates to the field of light curing technology, in particular to an optical mechanism for offset printing light curing. Background technique [0002] UV-LED light source has the characteristics of long service life, high reliability, high luminous efficiency, low power consumption, no heat radiation, and environmental protection. In recent years, it has been more and more widely used in UV curing and printing, especially In the fields of high-power offset printing and varnish machines, high-power-density UV-LED light source modules have been adopted by most equipment factories. At present, most of the light source heads of equipment in the industry are composed of lamp beads pasted on circuit boards such as copper substrates. The UV-LED module is realized by adding light-emitting sheets and glass lenses. This method is composed of a single lamp bead. Since a lot of lamp beads need to be pasted on the light source head, the production eff...
