Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments are merely illustrative of the present invention and are not particularly limited.

Reference is made to figures 1 and 2. The utility model provides a LED lamp area of many LED lamp pearl parallel of resistance, its includes circuit board, resistance module 1 and lamp pearl module 2, above-mentioned resistance module 1 with above-mentioned lamp pearl module 2 welding on above-mentioned circuit board and be series connection each other, above-mentioned resistance module 1 comprises a plurality of resistances 10 parallelly connected, above-mentioned lamp pearl module 2 just comprises a plurality of LED lamp pearl 20 parallelly connected.

The circuit board is not shown in the drawings, and is a known technology, the circuit board is a flexible circuit board, such as a known FPC circuit board or a known PCB circuit board, various electronic components are soldered on the circuit board by means of soldering, and a layer of flexible insulating transparent material, such as known PP, PET plastic, etc., is usually encapsulated and encapsulated on the outer layer of the circuit board. The lamp strip is a slender lighting device, in the prior art, the LED lamp beads are usually welded on a circuit board in a series connection manner, and then are packaged by using a flexible material, and of course, resistors are also connected in series between the LED lamp beads. The LED lamp strip has the advantages that in the manufacturing or using process, when one device is subjected to desoldering or insufficient soldering, the whole lamp strip cannot be lightened, and particularly when the lamp strip needs to be wound and bent for use, the device is likely to be desoldered by external force. This use neotype scheme to improve into the parallelly connected resistance module of lamp pearl module and a plurality of resistance that constitutes by a plurality of parallelly connected lamp pearls with original single LED lamp pearl and resistance, as long as have a device normal work then this module can all normally work in lamp pearl module or resistance module, can reduce the fault rate in whole LED lamp area like this.

In the embodiment of the present invention, the resistance of the resistor 10 in the resistor module 1 is equal. The total resistance of the resistance module is smaller than the resistance of any single resistance, when the resistances of the resistances in the resistance module are equal, the total resistance is the largest, and when one of the resistances is in an open circuit, the influence on the total resistance is the smallest, so that the influence on the total current is the smallest.

In the embodiment of the present invention, the number of the resistors 10 in the resistor module 1 is 2-5. The more resistors 10 connected in parallel in the resistor module, the higher the safety of the device, but at the same time, the overall increase of the manufacturing cost is also caused, and the slender structure of the lamp strip also makes it unsuitable for connecting a particularly large number of resistors in parallel, so that the number of the resistors 10 is set to be 2-5, which is reasonable. Also preferably with the LED lamp pearl that selects the model the same to LED lamp pearl 20 in the lamp pearl module 2, to the number of LED lamp pearl, with the in-service use demand as the standard.

Generally, the number of the resistor modules 1 is less than or equal to the number of the lamp bead modules 2. The resistor module 1 does not emit light, and mainly has the function of voltage division adjustment, and the lighting effect of the lamp strip is influenced by the excessive quantity of the resistor module. The lamp bead modules 2 and the resistor modules 1 may be connected in series at intervals one by one, or may be connected in series at multiple intervals, preferably, one resistor module 1 is connected in series between a plurality of lamp bead modules 2, for example, as shown in fig. 2, a resistor module 1 is connected in series between three lamp bead modules 2, and generally, 2 to 50 lamp bead modules 2 are connected in series between 1 resistor module 1, so that the lighting effect of the lamp strip is optimal. Here, the fact that one resistor module 1 is connected in series between 2 to 50 lamp bead modules 2 means that 2 to 50 lamp bead modules 2 are connected between two resistor modules 1 in the circuit, that is, the number of the lamp bead modules 2 in the interval may be equal or unequal, and the number of the lamp bead modules 2 in the interval may be 2 to 50.

The total current of the resistor module 1 is consistent with the working current range of the lamp bead module 2, the current overload which affects the LED lamp beads 20 due to the fact that the total current fluctuation of the resistor module 1 is too large because the resistor module 1 is damaged by a certain resistor 10 can be avoided, and the LED lamp beads 20 are still in the working current range when the resistor module 1 is at the minimum or maximum total resistance.

The above-mentioned embodiments only express a plurality of embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
