Embodiment Construction

[0012] Please refer to the attached figure 1 , 2 As shown in , 3, the light strip module is in the middle of the front of a rectangular PCB board, and a number of LED lamp beads 3 are installed in an orderly series. Two copper foil strips 5 and 4 are arranged in parallel on both sides of the lamp beads 3. The electrodes supply power to the LED lamp bead 3 to form a light strip module. On the back of the PCB board, corresponding to the two copper foil strips 4 and 5 parallel to the front of the PCB board, two wires 9 and 8 are respectively used to connect to the two wires parallel to the front of the PCB board. The starting ends B, A of the copper foil strips 4, 5 are connected to the terminals D, C electrodes, which is equivalent to connecting two wires 9, 8 in parallel on the two copper foil strips 4, 5 parallel to the front of the PCB board, so as to shunt the PCB. The current flowing through the two parallel copper foil strips 4 and 5 on the front of the board reduces the ...

Abstract

In order to solve the problem that a plurality of single LED lamp strip modules which are connected in series cannot be used, the invention provides a low-power-consumption LED series lamp strip. Thelamp strip is formed by connecting a plurality of lamp strip modules in series, two copper foil strip positive and negative electrodes parallel to the front face of a PCB are correspondingly arrangedon the back face of the PCB of each lamp strip module, and two wires are used for being communicated with the starting end electrodes and the tail end electrodes of the two copper foil strips parallelto the front face respectively, that is, the two copper foil strips parallel to the front face of the PCB are each connected with a wire in parallel. And the current flowing over the two parallel copper foil strips on the front surface of the PCB is shunted. The low-power-consumption LED series lamp strip has the advantages that the power loss on the copper foil of the PCB is greatly reduced, theservice life of the single lamp strip module is prolonged, and the brightness difference of the head lamp bead and the tail lamp bead due to the fact that the single lamp strip module is connected with too many lamp strips is avoided. More single LED lamp strip modules can be connected within the rated power range of the driving power supply, and the lamp strip can be connected as long as 10 meters generally.

Description

technical field [0001] The invention relates to LED lighting, and mainly relates to a connection device for series-connected LED light strips. Background technique [0002] LED lights are currently recognized as green lighting. In addition to entering ordinary homes as indoor lighting, they are also widely used in media indoor and outdoor advertisements, light boxes, light strips, decorative lighting for buildings, bridges, elevated roads, squares, parks, and courtyards. Most of these applications need to connect several single LED light strip modules with limited length to form a certain length of light strip. At present, the common connection method is to directly connect single LED light strip modules in series. Due to the limited thickness and width of the copper foil on the PCB board of the light strip module that supplies power to the LED lamp beads, as the connected single light strip module The more it is, the voltage drop on the copper foil of the PCB board will gr...
