Background technique
With the development of LED technology, illumination application has been extended to ultraviolet regime from the visible-range of RGB.
The application of ultraviolet band is concentrated mainly on uv-exposure, solidification and ultraviolet-sterilization field.
Ultra-violet curing is to irradiate coating using ultraviolet light, the reaction such as radiation polymerization, crosslinking with radiation is generated, rapidly by low molecule
Quantity of material is transformed into the chemical process of high molecular weight product, is free of solvent or solvent containing minute quantity in system, liquid film is several after irradiation
100% solidification, thus VOC（Volatile organic compounds）Discharge amount is very low.Uv-exposure principle is similar with ultra-violet curing, is
It is reacted by ultraviolet source and coating, forms the protective layer that can block etching.Since uv-exposure needs transform graphical
The precision of information, figure also proposes particular/special requirement to ultraviolet source.In order to reach enough graphical information transfer capabilities, light is needed
The angle in source is sufficiently small.Traditional uv-exposure technology is designed based on mercury lamp, and the feature of mercury lamp approximation point light source, benefit are utilized
With ellipsoid reflecting surface, the light source that mercury lamp issues is reflected into approximately parallel light beam.As LED technology replaces the wave of traditional mercury lamp
Tide, ultraviolet LED source of parallel light have appeared in the public visual field.Due to the bottleneck of current ultraviolet LED technology, the amount of LED chip
Sub- efficiency is restricted, and can not generate the ultraviolet radioactives of enough energy in single chiplet, it is therefore desirable to more chips are integrated,
The density of arrangements of chips increases, and limits the optical design for realizing parallel light output.For this reason, it may be necessary to design sufficiently compact optics
Structure realizes the ultraviolet collimated light beam of large area.
In order to solve the above-mentioned technical problem, the present invention devises a kind of array ultraviolet LED source of parallel light, and the array is purple
Lens array in outer LED source of parallel light is made of multiple lenslets, each lenslet works independently, and ultraviolet LED is issued
Light beam pool approximately parallel light beam；Ultraviolet LED light source is located at below lens, and is in close contact with heat-conducting plate, by leading
Hot plate conducts the heat that ultraviolet LED light source work generates, and radiating bottom plate receives the heat of heat-conducting plate transmitting, radiating bottom plate
Pass through radiating bottom plate braced frame simultaneously support lens array, guarantee ultraviolet LED light source be always positioned at lens array focus it is attached
Closely.Lens array is integrally formed, and avoids the occupied space of lens support structure part, it is very big reduce between lens between
Away from improving the energy density of ultraviolet light beam.In short, the array ultraviolet LED source of parallel light is reasonable in design, heat dissipation effect
It is good, it is suitble to promote the use of.
Summary of the invention
In order to overcome defect present in background technique, the technical solution adopted by the present invention to solve the technical problems is：
