In addition to the light source, they include all parts needed to fix and protect the light source, as well as the wiring accessories necessary for connecting to the power supply. Lamps are lighting tools, so testing their light sources is very important.

[0030] Working principle and process:

[0031] When using a fixing structure for testing the performance of a lamp, the flip cover (2) is opened to place the lamp body (20) inside the housing (1), and then the motor (17) located at the bottom of the base (3) is turned on. The motor (17) drives the screw rod (16) to start rotating. The screw rod (16) drives the plurality of sliding blocks (15) outside to start moving while rotating. When the sliding blocks (15) move, the second connecting plate (13) and the first connecting plate (12) start to push the fixing sleeve (11) to move. At the same time, the round head shaft (10) inside the fixing sleeve (11), including the moving block (9) on the top of the round head shaft (10), starts to move at the same time. When the moving block (9) moves to fit with the bottom surface of the lamp body (20), it can be clamped and fixed. Here, the connecting shaft (14) is used to fix the first connecting plate (12) and the second connecting plate (13), and the notch sleeve is fixedly provided inside the base (3). (18) is used to prevent the sliding block (15) from falling when sliding. After the bottom is fixed, the middle part of the lamp body (20) can be clamped and fixed by the clamping block (7), and then the other end of the binding belt (8) is fixed to the outside of the fixing block (4) to form a secondary fixation. Here, the function of the spring (6) is to adjust the distance between the clamping blocks (7) to adapt to lamp bodies (20) of different specifications. The countersunk shaft (5) is used to fix the spring (6). After the lamp body (20) is fixed, the lamp body (20) switch is turned on. The light of the lamp body (20) will shine on the surface of the light source test board (19). The light of the lamp body (20) can be tested through the light source test board (19) to observe whether it meets the standard. A transparent glass is provided on the top of the flip cover (2). The tester can observe through the glass to prevent other light from interfering with the test.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
