Abstract

The invention provides LED light-emitting modules capable of being connected in series. The LED light-emitting module comprises a module body, an LED light-emitting circuit and a switching circuit, wherein the LED light-emitting circuit and the switching circuit are arranged in the module body; one end of the module body is an input end, and the other end is an output end; the switching circuit is provided with a common end and a plurality of connecting ends. When the switching circuit is switched on, each connecting end is switched on with the common end; when the switching circuit is cut off, all the connecting ends and the common end are cut off, and all the connecting ends are kept mutually cut off. The invention provides an LED lamp. The LED lamp comprises a driving power supply and at least one LED light-emitting module capable of being connected in series, and the output end of the driving power supply is connected with the input end of the first LED light-emitting module.

Description

technical field [0001] The present invention relates to an LED lighting module, in particular to a series-connectable LED lighting module Background technique [0002] The LED lights with external drive power are welcomed by users because their LED light-emitting modules can be designed into a relatively compact shape. [0003] A driving power supply is used to drive an LED lamp composed of a number of LED light-emitting modules that can be connected in series, because the number of LED light-emitting modules is variable, which is more in line with actual lighting needs. The LED lighting modules that can be connected in series have a double-terminal structure, one of which is an input terminal and the other is an output terminal. The output end of the drive power supply is connected to the input end of a series-connectable LED light-emitting module. If it is necessary to increase the number of LED light-emitting modules, the The method of connecting the output end of the l...
