Description
Technical field
The present invention relates to lens technologies field, and in particular to a kind of UVLED modules and its system with compound lens structure
Preparation Method.
Background technology
In recent years, UVLED (i.e. UV LED) needs photocuring technology in communication, electronics, optics, printing etc.
Field has been widely applied.Relative to traditional production technology in Hg lamp irradiation mode as main flow, UVLED has constant
The characteristic such as intensity of illumination, outstanding temperature control performance, quick response time, portable environmental-protection, more have relatively low adopt
Cost and almost nil maintenance cost are purchased, work is greatly promoted to the quality-improving and energy-saving serve of UV curing process
With.In order to further promote UVLED solidification effect, its light efficiency must also be increased.Because the single power of LED is small, send
Light it is uneven, it usually needs several LED chips are combined into area source, and pass through that optical lens sent it is scattered
Light carries out secondary light-distribution, to lift LED light extraction efficiency and change the distribution of its light.The difference of optical lens selects material simultaneously
Material can also have a direct impact such as quartz glass, K9 glass, silica gel to the transmissivity of ultraviolet light, the manufacture material of its lens
Cost is also one of the factor that must take into consideration.However, the preparation to said lens generally uses one-time formed in the prior art
A kind of material can only be used in technique, manufacturing process, is difficult to get both in terms of relatively low manufacturing cost and higher lens transmissivity.
Therefore, it is necessary to develop a kind of compound lens for UVLED modules, while cost is controlled, combination is not
With sexual valence it is higher prepare material, the disperse light that can send LED carries out secondary light-distribution, causes ultraviolet light this again
Possess excellent transmissivity under lens.
The content of the invention
It is difficult to what is got both in terms of in order to solve the relatively low manufacturing cost of UVLED lens in the prior art and higher lens transmissivity
Technical problem, the invention provides a kind of UVLED modules with compound lens and preparation method thereof.Compound lens is using twice
The technique of shaping, the higher different combinations of materials of optional sexual valence, the disperse light that LED can be sent by making it carries out two
Secondary luminous intensity distribution, make it that ultraviolet light possesses higher transmissivity under this lens again.
To reach above-mentioned purpose, the technical solution adopted by the present invention is as follows：
A kind of UVLED modules with compound lens structure, including substrate, UV LED chip and compound lens, it is described
UV LED chip is provided with several and is distributed on the substrate in array, and the compound lens is covered in the UVLED cores
The top of piece, it is characterised in that：
The compound lens includes first kind lenticular body, and the first kind lenticular body is placed directly within the UV LED chip
Surface, the first kind lenticular body is shaped as prolate cube, and its length and width size just covered on substrate
UV LED chip；
The compound lens also includes Equations of The Second Kind lenticular body, and the Equations of The Second Kind lenticular body is placed in the first kind lenticular body
Surface, the Equations of The Second Kind lenticular body is combined by several micro objectives, in the quantity and substrate of the micro objective
UV LED chip longitudinal arrangement number is identical, and the micro objective in spatial distribution in the UV LED chip just on
Side.
Further, the first kind lenticular body include being covered in the plane of incidence directly over the UV LED chip and with institute
It is half to state several micro objectives in the exit facet that the plane of incidence of Equations of The Second Kind lenticular body is in contact, the Equations of The Second Kind lenticular body
Cylindrical shape, its bottom surface is the plane of incidence for the rectangle being in contact with the exit facet of the first kind lenticular body, described small-sized
The top surface of mirror is the exit facet of the semi-cylindrical dissipated incident ray.The exit facet shape of the Equations of The Second Kind lenticular body can
To be adjusted according to required light-out effect, it is not limited to above-mentioned semi-cylindrical, such as can also be arc surfaced or
Other shapes.
Further, the first kind lenticular body prepare material and the Equations of The Second Kind lenticular body prepare material not phase
Together.
Further, the material for preparing of the first kind lenticular body is quartz glass, the preparation of the Equations of The Second Kind lenticular body
Material is silica gel.The ultraviolet light of the quartz glass is functional, and to be easily worked moulding and manufacturing cost relatively low for silica gel, above-mentioned
Combination of materials can reduce manufacturing cost while preferable transmissivity is obtained.Certainly, the first kind lenticular body prepares material
The material for preparing with the Equations of The Second Kind lenticular body can also be identical, such as be quartz glass, K9 glass and silica gel etc..
Present invention also offers a kind of preparation method of the UVLED modules including above-mentioned compound lens, wherein, described first
Class lenticular body and Equations of The Second Kind lenticular body are respectively prepared using injection molding process twice.
By adopting the above-described technical solution, the present invention achieves beneficial technique effect：Compared to one-time formed
Mirror body, compound lens of the invention includes first kind lenticular body and Equations of The Second Kind lenticular body, and two classes lens elder generation aftershaping can drop
The difficulty of low technique.In terms of selection, one-shot forming can only prepare material using one kind, and be divided into two lens-like methods, right
It can be used in different lens and different prepare material.This mode, which can be combined neatly, different to be prepared material to obtain
The transmission effects of different lens, so as to expand the application field of UVLED modules.
