The airflow can push the baffle 102 on one side of the exhaust strip hole. When it is necessary to maintain a high temperature environment, the airflow fan 101 and the baffle 102 are only in a static state, and the airflow is relatively difficult to circulate, thereby playing a role in heat preservation. The applicability of this test device is strong, and it can adapt power supply to LED lamps of different specifications and sizes. When the position of the contact electrode part 44 on the extension arm 43 needs to be adjusted, the elastic part 432 is pressed down to make the elastic part 432 disengage from the contact test platform 3.

During the continuous descent, the buffer part 504 is deformed to make the internal temperature detector 508 on the floating cover 507 close to the LED lamp being tested for aging, thereby facilitating the detection of the working temperature of the LED lamp.
