Lamp life monitoring circuit and lamps

Abstract

A lamp life monitoring circuit comprising: a half-wave extraction module connected in series with the lamp; a half-wave detection module connected to the half-wave extraction module to detect the arrival of the half-wave; a storage module connected to the half-wave detection module to record The number of half-waves, every time the half-wave detection module detects a half-wave, the number of half-waves is added and stored, and the storage module also stores the preset number of half-waves; the processing module is connected to the storage module, reads Get the number of half-waves stored in the storage module and the preset number of half-waves, and send a signal when the number of half-waves exceeds the preset number of half-waves; the indication module is connected to the processing module and indicates according to the signal sent by the processing module lamp life. The above lamp life monitoring circuit and lamps with the above lamp life monitoring circuit can detect the number of half-waves through the half-wave detection module, and the power-on time of the bulb can be obtained from the frequency of the alternating current combined with the number of half-waves, which is convenient for users to intuitively understand the number of bulbs elapsed time.

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp life monitoring circuit and a lamp. Background technique [0002] Existing electric lamps and lanterns often need to replace the bulbs for maintenance, but due to the different lighting locations of the lamps, the use time of each lamp is different, so the end of life of each bulb is also different, because the end of life of each bulb cannot be judged , Therefore, there is often a lamp change that is not timely or the bulb has not reached the service life of the bulb when changing the lamp, resulting in unfavorable work or waste of the bulb. Contents of the invention [0003] Based on this, it is necessary to provide a lamp life monitoring circuit. [0004] A lamp life monitoring circuit, comprising: [0005] Half-wave extraction module, connected in series with lamps; [0006] The half-wave detection module is connected with the half-wave extraction module to detect the arrival of the half...
