Abstract

The invention discloses an LED lamp protection circuit and belongs to the technical field of electronics. The LED lamp protection circuit comprises a power source, an LED lamp, a current detecting device, relays and a resistor. The power source is electrically connected with an input end of the current detecting device, an output end of the current detecting device is electrically connected with the first relay, an output end of the first relay is electrically connected with an input end of the LED lamp, one end of the resistor is connected between the current detecting and the relays after the resistor is connected with the second relay serially, and the other end of the resistor is connected between the relays and the LED lamp. The current detecting device is added, when current is too high, the current detecting device can control the current to flow through the resistor and flow through the LED lamp through the resistor, current of the LED lamp is reduced, and the LED lamp is protected.

Description

technical field [0001] The invention relates to an LED lamp circuit, in particular to an LED lamp protection circuit, which belongs to the field of electronic technology. Background technique [0002] With the development of society, LED lamps have become the main fluorescent lamps in the market due to their energy saving and environmental protection, and are accepted by consumers. When it is too large, it is easy to cause damage to the LED lamp, resulting in waste of resources and increased costs, which is not conducive to improving economic benefits. Contents of the invention [0003] The purpose of the present invention is to provide a LED lamp protection circuit, which can detect the flow of the circuit and reduce the current to play a protective role. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: the LED lamp protection circuit includes a power supply and an LED lamp, and also includes a current detection d...
