Of course, the interval of the rotation angle of the third holder unit 600 may be variously modified.

That is, when the third holder unit 600 is rotated about the second rotation axis B and the third measurement surface for the light source is formed, the first body unit 200 is the first body unit 200. It is rotated about the first axis of rotation (A) of.

Subsequently, after rotating the rotary block 320 to rotate the entire third holder unit 600 by 5 ° with respect to the second rotation axis B, the first main body unit 200 returns to the first The light illuminometer 40 measures the light of the light source while being rotated by 90 ° in both the left and right directions about the rotation axis A. Of course, the rotation angle of the first body unit 200 may also be changed.

On the other hand, when comparing the position of the light source installed in the second holder unit 500 for measuring the B-plane and the position of the light source installed in the third holder unit 600 for measuring the C-plane, the second An angle formed by the front center axis 1 of the light source installed in the holder unit 500 and the second rotation axis B on the second body unit is 90 °, and the front center axis of the light source installed in the third holder unit 600. And the angle formed by the second rotation shaft B on the second body unit is 0 °. Therefore, the measurement surface of the light source to be measured varies depending on the angle formed between the front center axis 1 of the light source and the second rotation axis B. FIG.

As described above, the light source handling apparatus according to the present invention has a first holder unit, a second holder unit, and a third holder unit, which are selectively coupled to one handling body, thereby providing A- defined by the International Illumination Commission (CIE). There is an advantage that can measure the properties of light for the plane, the B-plane, the C-plane.

As described above, the present invention is not limited to the above-described specific preferred embodiments, and various modifications may be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. It is possible and such variations are within the scope of the present invention.

According to the present invention, the rotary block provided in the light source handling apparatus rotates together with the first body unit, or the rotary block rotates when the holder unit rotates about its own rotation axis. There is an industrial applicability to increase the productivity by being able to efficiently measure the optical characteristic values for the three defined planes.
