Abstract
The utility model discloses a novel circuit structure of LED lamp comprising a light emitting diode (LED), which is characterized in that the LED is connected in parallel to form a group; multiple groups of the LEDs are connected in series, the positive terminal of which is connected with resistance R2 in series and the negative terminal of which is connected with resistance R1 in series; the other end of the resistance R1 is divided into two braches that are connected with the anode of rectifier diode D1 and D2; the other end of the resistance R2 is divided into two braches that are connected the cathode of rectifier diodes D3 and D4; the cathode of the rectifier diode D1 and the anode of the rectifier diode D3 are both connected with wire A and the cathode of the rectifier diode D2 and the anode of the rectifier diode D4 are both connected with wire B. The utility model has simple structure and stable performance due to DC power supply, and prevents LED from being burnt that occurs under condition of AC power supply. Meanwhile, the utility model can be randomly connected with form lamp cluster.
Description
Technical field
The utility model relates to person in electronics, specifically a kind of circuit structure of Novel LED light.
Background technology
Along with of the continuous application of LED light-emitting diode at industry-by-industry, people more and more come wide in range to the requirement of its scope of application, be not only on decorating, frequently to use colorful LED lamp, and in illumination, also gradually adopt the LED lamp of low-power consumption, reach the purpose of creating conservation-minded society.Based on the principle of LED lamp direct current supply, under the situation of civil power Alternating Current Power Supply, just need make design to the external circuit of LED lamp, make the LED lamp can be under the situation of Alternating Current Power Supply operate as normal.Though the LED lamp decoration product of existing traditional bridge rectifier reaches the purpose of direct current supply, can't connect backward, influenced its series connection and used.
The utility model content
The utility model proposes a kind of circuit structure of Novel LED light at the variety of problems of above-mentioned appearance.
The technical solution of the utility model
A kind of circuit structure of Novel LED light, include light-emitting diode, it is characterized in that: constitute one group after the described light-emitting diode parallel connection, behind the multi-group light-emitting diode series aiding connection, its positive terminal is in series with resistance R 2, its negative pole end is in series with resistance R 1, resistance R 1 other end be divided into two branch roads respectively with rectifier diode D1, the positive pole of D2 links, the other end of resistance R 2 be divided into two branch roads respectively with rectifier diode D3, the negative pole of D4 links, the negative pole of rectifier diode D1, the positive pole of D3 is all received on the lead A, the negative pole of rectifier diode D2, the positive pole of D4 is all received on the lead B.
The utility model is that LED lamp group is inserted in the bridge rectifier of rectifier diode D1, D2, D3, D4 composition, and the electric current by light-emitting diode group is a direct current like this, has realized the purpose of direct current supply; Secondly, when large-scale color lamp decoration occasions, when needing a large amount of LED lamp strings, organizing the utility model product can couple together lead A, B respectively more, can form the lamp string of required length.
The utility model is simple in structure, because direct current supply, it is more stable to work, and has avoided the alternating-current power supply LED lamp easily to burn phenomenon, simultaneously, can be connected to form the lamp string arbitrarily.
The utility model light-emitting diode group can substitute with the light-emitting diode group that single light-emitting diode or other series/parallel form.
