Hereinafter, to the UV LED scan-type energy of light source evenness tester utilizing this utility model to provide
The process that the 100 pairs of UV LED scan-type light sources carry out energy uniformity test illustrates.
First, UV LED scan-type light source S is installed to the push rod 41 of support 40 so that UV LED
The radiating surface of scan-type light source S is towards the UV optical sensor 30 being arranged at below push rod 41.In this enforcement
In example, illustrate using the scanning type area light of rectangle as UV LED scan-type light source S.
When starting to test, light each of UV LED scan-type light source S, UV LED scan-type light source S
Position sends downwards ultraviolet.Travel mechanism 60 controls the first mobile station 12 and the second mobile station 22 is moved
Dynamic so that the UV optical sensor 30 in the second mobile station 22 moves to test original position, such as, with
The summit P of rectangular surfaces light source S0' (that is, the drift angle at right back) just to original position P0, and at this
The summit P of position measurement UV LED scan-type light source S0Light intensity L1 corresponding to '0.Then, moving machine
Structure 60 controls the second mobile station 22 and moves, by original position P along the second guide rail 21 in second direction B0
The mobile summit P to the rectangular surfaces light source S other end1' position corresponding to (that is, the drift angle at left back)
P1, and in this moving process, measure rectangular surfaces light source S light corresponding everywhere in second direction B respectively
Strong L1, i.e. the formula that is scanned measures (scanning sensing).Like this, by the one of rectangular surfaces light source S
The process that end (right-hand member or left end) B in a second direction is scanned to the other end (left end or right-hand member),
It is referred to as single pass.The available multiple light intensity value L1 of scanning for the first time.Controlling can with data processing unit 50
Obtain from UV optical sensor 30 and scan each light intensity value L1 obtained for the first time, and to these light intensity values L1
It is integrated processing, obtains the first energy value (light intensity data) E1.

Mobile to right-hand member, in the process, second row of rectangular surfaces light source S measured successively by UV optical sensor 30
Light intensity L2 corresponding everywhere in second direction B, i.e. carries out second time and scans, be similarly obtained multiple
Light intensity value L2.Similarly, control to obtain second from UV optical sensor 30 with data processing unit 50
Each light intensity value L2 that secondary scanning obtains, and be integrated these light intensity values L2 processing, obtain the second energy
Value E2.Then, travel mechanism 60 controls again on the first mobile station 12 A in a first direction along the first guide rail
11 forwards move a position so that the first mobile station 12 arrives the third line, and UV optical sensor 30 enters
Row third time scanning, controls to obtain the 3rd energy value E3 with data processing unit 50 by integral and calculating, as
This repeats, until last column N (that is, a line of forefront) the also end of scan on first direction A,
Now, E1, E2, E3 ..., this N number of energy value of EN are obtained.Control and data processing unit 50
By comparing the maximum Emax and minima Emin determined in this N number of energy value, and minimum can be utilized
Value Emin and maximum Emax ratio, i.e. Emin/Emax weighs the energy of UV LED scan-type light source
The amount uniformity: Emin/Emax is the least, and the energy uniformity is the lowest；Emin/Emax is the biggest, and energy is uniform
Spend the highest.It should be noted that it is equal to weigh the energy of UV LED scan-type light source with Emin/Emax
Evenness is an example, according to light intensity value everywhere, it is also possible to utilize alternate manner to weigh UV
The energy uniformity of LED scan-type light source.
In this utility model, due to the first guide rail, the first mobile station, the second guide rail and the second mobile station
Setting, therefore, UV optical sensor can be right against each point of UV LED scan-type light source and carry out light intensity inspection
Survey, and be prone to UV LED scan-type light source is carried out intensive detection, therefore, it is possible to quickly, accurately,
Detect the UV LED scan-type energy of light source uniformity all sidedly.
Above in conjunction with accompanying drawing, embodiment of the present utility model is described, but this utility model is not
Be confined to above-mentioned detailed description of the invention, above-mentioned detailed description of the invention be only schematically rather than
Restrictive, those of ordinary skill in the art is under enlightenment of the present utility model, without departing from this practicality
In the case of novel objective and scope of the claimed protection, it may also be made that a lot of form, these belong to
Within protection of the present utility model.
