Flashing light tester

Abstract

The invention discloses a flashing light tester including an external housing and a single-chip microprocessor. The single-chip microprocessor outputs a triggering signal which triggers a flashing light to flash and then flashing light of the flashing light collected by a photosensitive sensor is output and displayed through the single-chip microprocessor and a testing result is stored. The external housing is provided with an optical receiving window and a display window of the photosensitive sensor. According to the invention, the photosensitive sensor is adopted to measure whether the lightemits light or not, but not to measure whether the light is triggered or not, so that non-contact testing is realized. Light disassembly is not required, so that working load and labor cost are saved. Besides, the flashing light is small in size, suitable for being held by hand and convenient to carry.

Description

technical field [0001] The invention relates to a flashing lamp tester. Background technique [0002] The on-site testing of traffic flashing lights has been a problem that has plagued the industry. For the production factory of flashing lights, there are complete sets of test instruments, and the test is no problem, but these test instruments are bulky and heavy. For the construction site of flashing lights, generally It is a high-altitude operation, and it is impossible to move the desktop test instruments used in the factory to the construction site, which requires hand-held and portable test instruments. [0003] Existing light explosion test also has the following problems except that it is bulky and cumbersome: [0004] 1. Test the voltage at both ends of the energy storage capacitor to judge whether the capacitor is discharged by the lamp to infer whether the lamp is lit. In fact, it can only test whether the lamp is triggered. If the lamp is damaged or the energy st...

AI Technical Summary

Problems solved by technology

[0004] 1. Test the voltage at both ends of the energy storage capacitor to judge whether the capacitor is discharged by the lamp to infer whether the lamp is on. In fact, it can only test whether the lamp is triggered. The energy capacitor will still be discharged, so it may not be possible to measure whether the lamp is lit, nor can it measure the degree of aging

[0005] 2. For contact measurement, it is necessary to disassemble the lamp to measure the voltage at both ends of the energy storage capacitor, which will increase the workload and labor costs

[0007] 4. Can only test gas flashing lights
