Description

Voltage series LED light string module

The invention relates to a light string module, in particular to a plurality of sets of light emitting diode light string modules electrically connected in series by voltage.

The light-emitting diode is a solid-state semiconductor component, which is a luminescent light, has the advantages of small volume, long life, low power consumption, fast reaction rate, and excellent shock resistance. In recent years, LED light strings have been widely used in trees. , landscaping, landscape windows, signboards and the decoration of the exterior walls of the building to add to the beauty of the objects.

There are two types of LED lamp string modules that have been disclosed. The LED lamp group 100 shown in the first figure is connected in parallel with the power converter 200 by the anode pin 101 and the cathode pin 102. The signal line 201 of the converter 200 is coupled to the signal input terminal 103 of the LED light unit 100, and the signal output terminal 104 is coupled to the signal input terminal 103 of the next LED light unit 100. When the signal line 201 of the power converter 200 outputs a control signal, the LED lamp group 100 can be selectively, one by one, or all, to generate a change. However, such a connection method consumes a large current, that is, the power converter 200 is difficult to manufacture in order to supply a large current, and the cost is high, or the LED lamp group 100 that can be connected in parallel is limited.

The LED lamp set 100 shown in the second figure is connected in series with the power output end of the power converter 200, and the signal line 201 of the power converter 200 is connected to the signal input end 103 of the LED lamp set 100, and the number output is The terminal end 104 is coupled to the signal input terminal 103 of the next LED light group 100. When the power converter 200 outputs a control signal, the LED light group 100 can also be selectively, one by one, or all, to generate a change in brightness. Since the LED lamp group 100 is connected in series, the current is small, the power converter 200 is easy to manufacture, and the cost is low. However, the stringable LED light group 100 is limited, depending on the DC voltage supplied by the power converter 200, and the higher the voltage of the LED light group 100, the higher the voltage required. At this time, the power converter is not easy to manufacture, and the cost is relatively increased.

Since the above LED lamp set 100 is connected in multiple groups, it will be subject to many limitations such as power supply and cost. Moreover, the lamp string module design of the first figure or the second figure which is completed by the LED lamp group 100 cannot be connected in series with another group of lamp string modules. Therefore, how to make the light string module composed of the LED light group can be connected in series with another light string module is a problem to be solved by the present invention.
