Description

Technical Field

[0001] The utility model relates to a device for detecting the height of a patch LED lamp on an LED light bar, and belongs to the technical field of LED light bars. Background Art

[0002] LED light strips refer to SMD LEDs assembled on strip-shaped FPCs (flexible circuit boards) or PCB hard boards. When the installation height of the SMD LED lights is not in compliance, the contact between the SMD LED lights and the light strips will be unstable. During use, the LED lights will sometimes light up and sometimes not. In addition, the different heights of the SMD LED lights will also affect the overall lighting effect of the LED light strips. Therefore, the height of the LED light strips needs to be tested before leaving the factory.

[0003] The utility model with patent number 202022133737.4 provides a device for detecting the height of a patch LED lamp on an LED light strip. The utility model places the LED lamp on the support plate through the setting of a support plate, a through hole, a sliding rheostat, a switch, an ammeter, an iron sheet and a push rod motor, and then fixes the LED lamp on the support plate through a telescopic rod and a fixing plate in cooperation with a spring, and then starts the push rod motor to push the LED lamp into the through hole, and then pushes the iron sheet to move, so as to change the resistance value of the sliding rheostat. If the LED lamp is qualified, the ammeter displays a qualified ammeter value. When the LED lamp is unqualified during detection, the value on the ammeter is greater than or less than the current value when it is qualified, so that the height of the LED lamp can be detected quickly and accurately, which is suitable for wide promotion and use; however, half of the LED light strip is very long during production. When detecting the height of the patch LED lamp, if it is manually operated, the detection efficiency is low, and because the LED light strip itself is relatively soft, the LED light strip as a whole is prone to bending during monitoring, which affects the detection result of the patch LED lamp.
