High-power and high-uniformity miniature ultraviolet LED illuminator

Abstract

The invention belongs to the technical field of LED illuminators, and particularly relates to a high-power and high-uniformity miniature ultraviolet LED illuminator which comprises a first LED lamp bead, a second LED lamp bead, a third LED lamp bead, a first collimating lens combination, a second collimating lens combination, a third collimating lens combination, a first light combining mirror, asecond light combining mirror, a focusing lens and a square rod. The second collimating lens combination is located on the right side above the first collimating lens combination, the third collimating lens combination is located on the right side of the second collimating lens combination, the first collimating lens combination comprises a first small collimating lens and a first large collimating lens, the first small collimating lens is located on the left side of the first large collimating lens, a first LED lamp bead is installed in the first small collimating lens, the densely-packaged UV-LED array coupling packaging lamp bead has very high energy, it is guaranteed that the light output energy is high, the size is small, and the size of the LED illuminator can be reduced.

Description

technical field [0001] The invention relates to the technical field of LED illuminator, in particular to a miniature ultraviolet LED illuminator with high power and high uniformity. Background technique [0002] LED lights refer to lamps that use light-emitting diodes as light sources. Generally, silver glue or white glue is used to cure semiconductor LEDs on the bracket, and then silver or gold wires are used to connect the chip and the circuit board, and the surroundings are sealed with epoxy resin for protection. The role of the inner core wire, and finally install the shell. LED lights have the advantages of energy saving, longevity, environmental protection, shockproof, etc., and can directly emit seven colors of light. They are usually used in traffic lights, display screens, car lights, ultraviolet full digital projection and other fields. [0003] At present, ultraviolet full digital projection technology is more and more widely used in industry, such as 3D printing...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-power, high-uniformity micro-ultraviolet LED illuminator to solve the problems presented in the above-mentioned background technology. At present, ultraviolet full-digital projection technology is more and more widely used in industries, such as 3D printing, computer screens, Computer plate printing and maskless lithography technology, therefore, how to improve the speed and resolution of the ultraviolet full digital projection system is becoming more and more important in production. The light output energy uniformity of the existing LED illuminator is not good, and the light output energy is not good. High, the problem that light loses more energy during transmission
