It is middle to project, it is shaped as dome-type shape when depressed part 13, and LED 12 is when being evenly distributed on the depressed part 13 of dome-type, can
So that the light that LED 12 is launched projects the opening of depressed part 13 from multi-angle, build one kind and more conform to test request
Ambient light；And in the present invention, can be separately provided per LED lamp 12, can both adjust every LED lamp 12 colour temperature,
The parameters such as brightness value, it is also ensured that the uniformity of various parameters in whole LEDs 12, improve the environment of the construction of LED 12
The precision of light, substantially reduces the error of test, improves the validity of ambient light angle of visual field test.Present invention also offers one
Means for correcting 2 is planted, for detecting the parameter such as actual colour temperature, brightness value of all LEDs 12 in testing light source 1, passes through and corrects dress
Put 2 itself function or by other connecting test light sources 1 of control terminal 3, it is directly or all by 1 pair of testing light source
The parameters such as colour temperature, the brightness value of LED 12 are corrected, and the parameter of all LEDs 12 is met test request, without independent
Each LED 12 is individually corrected, the efficiency of work is substantially increased.The present invention also proposes a kind of test system, the survey
Test system controls testing light source 1 using control terminal 3, and the parameters such as colour temperature, the brightness value of LED 12 are corrected by control terminal 3,
Make the parameter of LED 12 more accurate, be also easier to automation mechanized operation.When containing means for correcting 2 in test system, increase
The efficiency that testing light source 1 is corrected to LED 12, makes the ambient light angle of visual field test more architecture, also further increases survey
The efficiency and validity of examination.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize
Equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations
Technical field, be included within the scope of the present invention.
