Flexibly-increased-and-decreased multi-device multi-unit loop type line connection structure

Abstract

The invention relates to a flexibly-increased-and-decreased multi-device multi-unit loop type line connection structure. The flexibly-increased-and-decreased multi-device multi-unit loop type line connection structure comprises a plurality of light emitting devices or irradiating devices, a power plug or input terminal and a power socket or output terminal, the multiple light emitting devices or irradiating devices are divided into a plurality of gathering units, each gathering unit comprises at least two light emitting devices or irradiating devices, the multiple light emitting devices or irradiating devices in each gathering unit are connected in parallel, and the multiple gathering units are connected in series to form a total gathering unit. Under the condition that multiple device combinations are used, influences of faults of certain units or certain devices on normal use of the combined devices can be avoided, the line voltage stability and normal work can be effectively kept, and the number of the light emitting devices or irradiating devices can be increased or decreased according to actual needs.

Description

【Technical field】 [0001] The present invention relates to the circuit structure of light-emitting devices or lighting devices, in particular to a circuit structure that can increase or decrease the number of light-emitting devices or lighting devices according to needs, and can keep the line voltage stable when one or some of the devices are faulty or damaged. And the loop-type line connection structure of multi-device and multi-unit that can be flexibly increased or decreased in normal work. 【Background technique】 [0002] Light-emitting devices and lighting devices are widely used in various fields of human life. Among them, lighting devices can provide lighting for people's production, life, work, study, etc., while light-emitting devices can be used as lighting decorations such as Christmas trees, handicrafts, advertising light boxes, Light source for product working status indication, electronic signboard, etc. Existing light-emitting devices and lighting devices are u...

AI Technical Summary

Problems solved by technology

When the existing light-emitting devices and lighting devices are used in connection with multiple devices, for example, when multiple LED lamp beads are connected to form a Christmas decoration light string, the traditional connection method is parallel connection or series connection. The defects of this single connection method are obvious.

In the traditional parallel structure, each device is connected in parallel on the power supply wire, which inevitably causes the problem of voltage drop

When multiple devices are used in series, if one of the multiple devices in series fails, it will cause the voltage of other devices to rise, thereby increasing the load on other devices and greatly shortening the service life of the devices that are still working. It may even damage other components and cause the entire light string to fail to operate normally

Therefore, traditional light-emitting devices and lighting devices have defects such as unreasonable connection, unsafe use, and unstable work when multiple devices are used in combination.
