Test circuit for discharge time of lamp

Abstract

A test circuit for discharge time of a lamp is used for recording the discharge time of the lamp and comprises a timing module and a photosensitive control module. The timing module is used for recording the discharge time of the lamp. The photosensitive control module is used for controlling timing state of the timing module and connected with the timing module. If the photosensitive control module senses the lamp discharging, the timing module is controlled to start to time by the same; if not, the timing module is controlled to stop timing by the same. The test circuit for the discharge time of the lamp adopts the photosensitive control module to sense the discharge state of the lamp. When the lamp is in discharging, the photosensitive control module is conducted; when the lamp stops discharging, the photosensitive control module is cut-off. The timing module is connected with the photosensitive control module and controlled by the conducting state of the same. when the photosensitive control module is conducted, the timing module starts to time; when the photosensitive control module is cut-off, the timing module stops timing. Thus, the accurate discharge time of the lamp is recorded by adopting the test circuit with simple structure.

Description

technical field [0001] The invention relates to a lamp test circuit, in particular to a simple and accurate lamp discharge time test circuit. Background technique [0002] With the development of the lighting industry, the discharge time of mobile and portable lamps is usually a theoretical value calculated from the theoretical load power and battery capacity. If the exact value of the discharge time of the lamp needs to be obtained, the actual charge and discharge record is generally made by the experimental method. At present, most lighting manufacturers in the industry rely on manual recording time for discharge time, which results in the testing of lighting discharge time is not only labor-intensive but also has large recording errors. SUMMARY OF THE INVENTION [0003] Based on this, a simple and accurate lamp discharge time test circuit is provided. [0004] A lamp discharge time test circuit for recording the discharge time of the lamp, comprising a timing module f...
