UV LED light source structure and parallel light exposure machine

Abstract

The invention relates to the technical field of exposure machines, and discloses a UV LED light source structure and a parallel light exposure machine. The UV LED light source structure comprises a UV LED lamp head, a fly eye lens module, a plane mirror and a spherical mirror, wherein the UV LED lamp head, the fly eye lens module, the plane mirror and the spherical mirror are sequentially arranged along a light path direction of the UV LED light source structure; a UV LED lamp bead is arranged in a UV LED; the UV LED lamp head and the fly eye lens module are adjacently arranged in parallel; the UV LED lamp head is adjacently connected with the fly eye lens module in parallel through an adjusting mechanism capable of adjusting the distance between the UV LED lamp head and the fly eye lens module; the UV LED lamp bead is arranged in front of the fly eye lens module; and parallel light for exposure is formed by the fly eye lens module, the plane mirror and the spherical mirror. The UV LED light source structure is applied to an existing parallel light exposure machine; equipment does not need to be upgraded by a customer and does not need to be transformed on a large scale; the low-temperature, energy-saving, environment-friendly and safe exposure machine employing the UV LED light source structure can be obtained with the least cost; the production delay is avoided; and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of exposure machines, in particular to a UVLED light source structure and a parallel light exposure machine including the UVLED light source structure. Background technique [0002] refer to figure 1 Shown is the light source structure 1 of a traditional parallel light exposure machine. The traditional parallel light exposure machine uses an ultra-high pressure mercury lamp 10 as a light source. The ultra-high pressure mercury lamp 10 first collects light through an elliptical mirror 11, and the light converges to On a first plane mirror 12, the first plane mirror 12 transmits the high-calorie IR light (infrared light) part in the light of the ultra-high pressure mercury lamp 10, and reflects and converges the UV light (ultraviolet light) in the ultra-high pressure mercury lamp 10 to On the second plane mirror 13, the second plane mirror 13 further reflects and converges the UV light almost without loss to ...
