The illuminometer 80 is fixed to a side of the third sliding portion 73 away from the adjusting portion 72. The sensor 90 may be a Chaise Coupled Device (CCD) lens or a Complementary Metal Oxide Semiconductor (CMOS) lens. In this embodiment, the sensor 9 is a CCD lens located directly above the luminance meter 80, and with - CCD ^ 100102199 Form No. A0101 Page 9 / 23 pages 1002003919-0 201231941 Air machine (Fig. not shown) is connected to transmit the data measured by the luminance meter 8 x to the xCCD measuring machine for the operator to analyze and judge whether the luminance value of the backlight module to be tested meets the standard. [0016] [0017] [0017] 4 together with the ® 15 'When testing the brightness of the backlight module to be tested, firstly - the backlight module 200 to be tested is placed on the carrier 40 In the portion 44, the positioning member 43 is adjusted, so that the sliding column 431 of the positioning member 43 slides along the corresponding sliding slot 421 until the locking portion 432 abuts the backlight module 200 to be positioned to be positioned and held. The backlight module 200 to be tested prevents the backlight module 2 to be tested from sliding. After the backlight module 200 to be tested is positioned, the corresponding first driving mechanism 3〇, the second driving mechanism 60 and the third driving mechanism 70 are activated, so that the luminance meter 8 is disposed on the first driving mechanism 30, The second driving mechanism 6〇 and the third driving mechanism 7〇 are driven to move along the X-axis, the Y-axis and the Z-axis direction as shown in the figure, so as to be on the three-dimensional structure of the backlight module 200 to be tested. The luminance is tested and the test results are transmitted to the corresponding CCD detector by the sensor 90 for analysis and judgment by the operator. It can be understood that the positioning member 43 is adjusted so that the bearing portion can be adapted to different types and sizes of the backlight module to be tested. It can be understood that the through groove 45 can also be filled with a corresponding expansion and contraction cymbal 46. One end of the expansion and contraction strip 46 is fixed to the end of the through groove 45, and the other end is connected to the column 51. When the column 51 slides in the slot bracket, the telescopic strip 46 can be shaped accordingly, thereby effectively filling the gap between the slot 45 and the base 51 to prevent dust from entering the table 2 Hey. It can be understood that the two guiding posts 724 can be omitted, and correspondingly, the guiding holes 732 corresponding to the guiding 100102199 Form No. A0101 Page 10/23 pages 1002003919-0 201231941 Column 724 can be omitted. [0018] It is apparent that the luminance testing device 1 of the present invention enables the luminance testing device 100 to move in a three-dimensional space by providing a plurality of driving mechanisms, thereby enabling rapid brightness measurement of a plurality of test points of the same object to be tested.攸量〇[0019] Comprehensive description of the invention meets the requirements of the invention patent, and patents are filed according to law.
