Abstract

An embodiment of the invention discloses a control circuit comprising a first power supply, a detection unit, a control unit, and an alarm unit, wherein the detection unit, the control unit and the alarm unit are connected in parallel to the two ends of the first power supply. The detection unit comprises a humidity-sensitive probe. If the humidity-sensitive probe is exposed to water, the humidity-sensitive probe is conducted, and the control unit and the alarm unit work. When the control unit is working, the control unit sends a switching signal to an external circuit. When the alarm unit is working, the alarm unit sends an alarm signal. According to the control circuit provided by the invention, the alarm circuit alarms automatically under control to remind a user in time when the humidity-sensitive probe detects that water exists in the control circuit. By applying the control circuit to a lighting device, the control circuit can automatically cut off power supply to a driving unit and a lighting light source when water is detected in the lighting device, so as to avoid short circuit, explosion or other dangerous situations and improve the security of the circuit. The circuit provided by the embodiment of the invention is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a control circuit and a lighting device. Background technique [0002] With the development of electronic technology, electronic products have been popularized in various fields of life, such as electronic products such as home appliances and lighting devices, which bring great convenience to people's daily life. [0003] In order to adapt to different working environments and different weather conditions, the lighting device needs to be able to withstand wind and rain, and needs to still work normally in a humid environment, so the lighting device needs to have better sealing performance. [0004] Once water enters the lighting device, it will usually lead to a short circuit in the driving circuit and the lighting light source in the lighting device, so that the lighting device cannot be used normally, and there are safety hazards such as explosion.
