Description

technical field [0001] The invention relates to the technical field of UVA LED light source UVA curing, in particular to a UVA curing control system with centralized and distributed architecture capable of realizing centralized power management, distributed power supply and power detection, and improving system reliability and its control method . Background technique [0002] At present, photocuring is widely used in the printing industry. Previously, a large number of UV mercury lamps were used, which mainly had disadvantages such as large power consumption, short life of mercury lamps, and mercury in products. Various printing manufacturers have been looking for energy-saving alternative products to reduce operating costs. . The photon efficiency of LEDUVA has been improved rapidly. Compared with the energy consumption of the previous UV mercury lamps, it has reached the critical point of mass replacement applications. UVA LED has the advantages of long life, mercury-fr...

AI Technical Summary

Problems solved by technology

However, UV LED also has its inherent limitations, that is, it needs to strictly control its working current, fast over-current protection, and reasonable temperature change rate, otherwise it will easily lead to UVA LED failure or serious light decay

UV LED curing light source needs to work at high current to achieve high light intensity output, resulting in high distribution density of lamp beads and difficult heat dissipation, especially when there is excessive current of LED power supply or AC power supply, if there is no timely current and power limit, it is easy to Cause the lamp bead to overheat and fail (the lamp bead burns); the chip leads inside the UVA LED cannot withstand severe temperature changes, otherwise it will easily lead to mechanical shock caused by temperature, and in extreme cases, the lead wire will break and the lamp bead will fail; UVA LED LED lamp beads contain fixed components such as solder, glue, optical lenses, etc. Some materials will accelerate the attenuation of their performance under severe temperature changes and affect the reliability of the system.

[0003] The UVA curing control system with a fully distributed architecture requires multiple separate power supplies on the AC / DC power supply at the input end. Although it has the advantages of strong fault tolerance, it needs to be solved in terms of extremely high reliability and small size design.

In addition, the fully distributed architecture has the problem of multiple power supply wires, which brings difficulties and challenges in assembly, maintenance, and cost
