[0027] like Figures 2 to 3 As shown, Figures 2 to 3 The structure diagram of the first embodiment of the dimmer integrated module 2 is shown.

[0028] When switching to any type of dimmer 24, the dimming function is realized by manually adjusting the dimmer 24 to change the lighting state of the lamp to be tested; the stroboscopic test of the lamp to be tested in different dimming states is realized by the stroboscopic tester 3; the compatibility of the lamp to be tested is tested by using a variety of different types of dimmers 24 to perform dimming tests on the lamp to be tested, so as to ensure that the qualified lamp to be tested can be compatible with the dimming control of a variety of different types of dimmers 24 on the market, thereby meeting the actual needs of different users to use different dimmers 24 for stable dimming control. The overall test structure is simple, the test functions are diverse, and the test operation method is simple.

[0029] Specifically, in this embodiment, the dimmer switching module 23 includes eight dimmers 24 of different models and a multi-way rotary switch module 25; the two ends of each dimmer 24 are respectively connected to the live wire end of the power input end 21 and the corresponding contact 251 in the multi-way rotary switch module 25; the fixed contact 252 of the multi-way rotary switch module 25 is connected to the live wire end of the power output end 22; by turning the knob 253 of the multi-way rotary switch module 25, the fixed contact 252 and the corresponding contact 251 are turned on or off to switch the switching function of any contact 251 being turned on and the other contacts 251 being turned off. When the fixed contact 252 is turned on with any contact 251, the dimmer 24 corresponding to the contact 251 is turned on and works, and the dimming function of the lamp to be tested is realized by controlling the dimmer 24. Among them, the multi-way rotary switch module 25 is an eight-way rotary switch module.

[0030] It should be noted that the multi-way rotary switch module 25 is a prior art, and its structure and working principle will not be described in detail here.

[0031] In other implementations, the number of dimmers 24 in the dimmer switching module 23 can be adjusted according to the actual needs of the user; accordingly, a suitable multi-way rotary switch module 25 is selected according to the number of dimmers 24 set to realize the switching function of the multi-way dimmers 24.

[0033] Specifically, the lamp installation mechanism 53 includes a fixture fixing frame 531, a test fixture 532 and a fixing screw 533. The test fixture 532 is installed with the lamp to be tested; the test fixture 532 is installed on the fixture fixing frame 531, and both sides of the test fixture 532 are provided with clamping holes 534 at intervals. The fixing screw 533 passes through the clamping holes 534 and is fixedly installed on the fixture fixing frame 531, so that the test fixture 532 is fixedly connected to the fixture fixing frame 531. When it is necessary to adjust the test distance between the lamp to be tested and the probe part 31 of the strobe tester 3, by adjusting the corresponding clamping holes 534 and the fixing screws 533 to adapt and install, the installation position of the test fixture 532 can be adjusted to adjust the test distance, thereby meeting different test distance requirements of users, and the applicability is high.

When the dimmer switching switch module 23 is working, the stroboscopic test is performed on the lamps to be tested in different dimming states; when the dimmer switching switch module 23 is not working, the conventional stroboscopic test is performed on the lamps to be tested. The test mode switching is simple and the functions are rich, which can meet the actual needs of users for stroboscopic tests on various lamps.

[0040] The mode switching switch module 26 is preferably a six-pin forward and reverse toggle switch, but the present invention is not limited thereto.
