Automatic detection circuit and automatic detection device for life of emergency lamp

Abstract

The invention is applicable to the field of lamp detection and provides an automatic detection circuit and an automatic detection device for the life of an emergency lamp. The automatic detection circuit comprises a counting unit and a switching control unit, wherein two power ends of the counting unit are connected with an alternating-current power supply, the counting unit is used for recording the number of switching between the power output of the alternating-current power supply and the power output of a direct-current power supply; and a power supply end of the switching control unit is connected with a public end of the counting unit, double switching ends of the switching control unit are connected with double counting ends of the counting unit, and the switching control unit is used for automatically switching the power output of the alternating-current power supply and the power output of the direct-current power supply. According to the invention, the switching control unit is used to set test time to control the power switching between the direct-current power supply and the alternating-current power supply of the emergency lamp, and the counting unit is used to carry out switching counting, so that the automatic detection control over the service life of the emergency lamp is realized, and the detection accuracy and the detection efficiency are improved.

Description

technical field [0001] The invention belongs to the field of lamp detection, and in particular relates to an automatic detection circuit and an automatic detection device for emergency lamp life. Background technique [0002] At present, emergency lighting lamps must first undergo strict service life testing before leaving the factory, that is, the number of conversions and time of emergency lighting lamps from AC to DC are detected, and the corresponding parameters are recorded as important technical indicators for the service life of the emergency lighting lamps. [0003] However, at this stage, the emergency lighting lamps are usually switched on and off manually, and the parameters are recorded, which seriously wastes labor. Moreover, due to the inevitable mistakes in manual operation, the detection results are affected, and the detection efficiency is very low. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide an ...
