Lamp service life monitoring circuit and lamp

Abstract

The invention relates to a lamp service life monitoring circuit comprising a half-wave extraction module, a half-wave detection module, a storage module, a processing module, and an indication module. Specifically, the half-wave extraction module is connected in series with the lamp. The half-wave detection module is connected with the half-wave extraction module and is used for detecting half wave coming. The storage module, which is connected with the half-wave detection module, is used for recording the number of times of half waves; when the half-wave detection module detects a half wave each time, the number of times of half waves is increased by adding one and the half waves are stored; and the storage module also stores the preset number of times of half waves. The processing module that is connected with the storage module is used for reading the number of times of half waves and the preset number of times of half waves that are stored by the storage module; and when the number of times of half waves exceeds the preset number of times of half waves, a signal is emitted. The indication module that is connected with the processing module indicates the service life of the lamp according to the signal emitted by the processing module. According to the lamp service life monitoring circuit and the lamp having the same, the half-wave detection module detects the number of times of the half waves; and the power-on using time of a bulb can be obtained based on combination of an alternating current frequency with the number of times of half waves. Therefore, the user can know the time that the bulb has been used conveniently and visually.

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...
