[0027] As Figures 1 - 5 shown, a brightness tester includes a base plate 1, a fixed table 2, a lamp holder 3, a fixed block 4, and a push-button switch 5. The fixed table 2 is installed above the base plate 1, the lamp holder 3 is installed above the fixed table 2, the fixed block 4 is installed on the side of the fixed table 2, and the push-button switch 5 is installed above the fixed block 4. It further includes a testing mechanism 6 for testing the brightness of the LED lamp, and the testing mechanism 6 is installed on the base plate 1.

[0028] In the present utility model, the testing mechanism 6 includes an electric push rod 601, a lifting block 602, a sealing box 603, a brightness tester 604, and a sealing gasket 605. The lifting block 602 is fixed above the electric push rod 601, the sealing box 603 is fixed at the front of the lifting block 602, the brightness tester 604 is fixed inside the sealing box 603, and the sealing gasket 605 is installed below the sealing box 603.

The sealing gasket 605 is adhesively bonded to the sealing box 603, and the material of the sealing gasket 605 is rubber. After the LED lamp is installed, the electric push rod 601 is activated. The electric push rod 601 contracts to drive the lifting block 602 to descend. The lifting block 602 drives the sealing box 603 and the sealing gasket 605 to descend. The sealing gasket 605 descends to contact the bottom plate 1. At this time, the LED lamp is completely inside the sealing box 603. The sealing box 603 and the sealing gasket 605 cooperate to enable the brightness test to be carried out in a closed environment, thus ensuring that the test results are not affected by external factors.

[0029] In the present utility model, a pressing mechanism 7 is installed on the testing mechanism 6. The pressing mechanism 7 includes a stud 701, a nut 702, a clamping rod 703, a pressing block 704, and a pressing head 705. The nut 702 is installed outside the stud 701, the clamping rod 703 is fixed to the side of the stud 701, the pressing block 704 is installed at the end of the clamping rod 703 away from the stud 701, and the pressing head 705 is installed below the pressing block 704. The clamping rod 703 is welded to the stud 701, and the shape of the clamping rod 703 is a cuboid. When the sealing box 603 descends, the pressing block 704 and the pressing head 705 descend accordingly. When the sealing box 603 descends to the lowest position, the pressing head 705 presses the pressing switch 5, and the LED lamp is powered on accordingly. When the sealing box 603 rises after the test is completed, the pressing head 705 separates from the pressing switch 5, and the LED lamp is powered off accordingly. In this way, the automatic opening and closing of the LED lamp is realized, effectively saving electric energy.

[0030] In the above structure: When using the device, install the LED lamp to be tested on the lamp socket 3. After the LED lamp is installed, activate the electric push rod 601. The electric push rod 601 contracts to drive the lifting block 602 to descend. The lifting block 602 drives the sealing box 603 and the sealing gasket 605 to descend. The sealing gasket 605 descends to contact the bottom plate 1. At this time, the LED lamp is completely inside the sealing box 603. When the sealing box 603 descends, the pressing block 704 and the pressing head 705 descend accordingly. When the sealing box 603 descends to the lowest position, the pressing head 705 presses the pressing switch 5, and the LED lamp is powered on accordingly. The brightness tester 604 detects the brightness. After the test is completed, the electric push rod 601 extends to drive the sealing box 603 to rise. The sealing box 603 rises to drive the pressing block 704 and the pressing head 705 to rise. The pressing head 705 rises to separate from the pressing switch 5, and the LED lamp is powered off accordingly.
