Abstract
The invention provides a lamp fixture discharge timing circuit. The lamp fixture discharge timing circuit comprises at least two light-sensitive elements, a control unit, a display unit and a warning unit. The light-sensitive elements, when receiving light emitted from a corresponding light source, output corresponding sensing signals to the control unit. The control unit begins to perform discharge timing on corresponding lamp fixtures. When the control unit cannot receive the sensing signals, the control unit ends the discharge timing on the corresponding lamp fixtures. The control unit starts the warning unit to alarm to indicate that discharge of a certain lamp fixture ends, and controls the display unit to display the number and the discharge timing time of the lamp fixture which ends discharge, such that it is unnecessary for a tester to stay in a test environment to manually record the discharge time of the lamp fixtures, labor is saved, and the test working efficiency is improved.
