Abstract

The invention discloses an LED fault indication circuit and a lamp comprising the same, and belongs to the technical field of fault detection and indication. The LED fault indication circuit comprisesa voltage stabilization tube, a light-emitting diode and a resistor, wherein the voltage-stabilizing tube, the light-emitting diode and the resistor are connected together in series through a wire. The lamp comprises a plurality of LED lamps / LED group strings connected to an LED power supply; each LED lamp / LED group string is correspondingly provided with the LED fault indication circuit, and thetwo ends of the LED fault indication circuit are connected to the two sides of the corresponding LED lamp / LED group string. By virtue of the technical scheme, the fault point of the light source canbe quickly indicated, so that convenience is provided for subsequent maintenance, a worker does not need to go to every place for checking the fault point, the troubleshooting efficiency is improved,and the labor intensity of worker is reduced.

Description

technical field [0001] The invention belongs to the technical field of fault detection and indication, and specifically relates to an LED fault indication circuit and a lamp containing the fault indication circuit, and is especially suitable for fault indication of lamps with an LED series-parallel hybrid structure. Background technique [0002] At present, the LED light sources on the market are developing towards small and medium power. In order to meet the power demand, the lamps must meet the demand through the combination of series-parallel and hybrid structure of LEDs. The advantage of the series-parallel circuit structure is that it is flexible enough to meet people's various needs; however, the technical problem that the series-parallel circuit structure will bring is: once the LED light source fails and opens in a group connected in series, it will cause The whole lamp is not bright, if multiple lamps pass through this series-parallel hybrid circuit, it will cause t...
