Abstract
The invention discloses a novel LED lamp string circuit structure which comprises power supply input leads connected with a power supply. A plurality of LED lamps which are connected in series are connected between the power supply input leads. Resistors are connected to the two ends of each LED lamp in parallel. The novel LED lamp string circuit structure has the advantages that when one or more LEDs are taken off, the protecting resistors are connected to the LEDs in parallel so that normal working of a whole lamp string cannot be affected, and accordingly the situation that if one LED falls or LED failure happens in a single LED serial lamp string, an open circuit is formed, and therefore the whole lamp string cannot be turned on is avoided.
Description
Technical field
The present invention relates to LED illumination circuit field, especially a kind of New LED lamp string circuit structure.
Background technology
LED lighting bulb is more and more extensive in the application of every field, compares with traditional bulb and energy-saving bulb, and LED bulb has long service life, need not consider heat radiation and the advantage of environmental protection.LED lighting bulb has the trend replacing conventional bulb and energy-saving bulb gradually.In current LED lighting field, conventional is cascaded structure, if there is a lamp extremely steep or turn around in lamp string, can cause the open circuit of whole lamp string, thus cause whole lamp string not work.
Summary of the invention
The object of this invention is to provide a kind of New LED lamp string circuit structure, by each LED lamp two ends parallel resistance, solve in traditional LED lamp cascaded structure the problem having a lamp extremely to steep or turn around to cause whole lamp string not work.
In order to achieve the above object, the technical solution used in the present invention is.
New LED lamp string circuit structure, includes the electric current input lead be connected with power supply, is connected to the LED lamp of multiple mutual series connection, it is characterized in that between electric current input lead: each LED lamp two ends are also parallel with resistance respectively.
Effect of the present invention takes off one or several LED; because of protective resistance in parallel on LED; the normal work of whole lamp string can not be affected, as long as thus change single LED Series lamp string and have a LED to turn around or the open circuit that formed because LED extremely steeps thus cause the situation that a whole cluster of lamps, ornamental does not work.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present invention.
Embodiment
As Fig. 1: New LED lamp string circuit structure, include the electric current input lead be connected with power supply V, power supply is the power supply of 120V60HZ, is connected to LED lamp LEDl, LED2 of multiple mutual series connection between electric current input lead ... the lamp number of the numerical basis lamp string of LEDN, N.Each LED lamp two ends are also parallel with resistance Rl, R2 respectively ... RN.
Claims (1)
1. New LED lamp string circuit structure, includes the electric current input lead be connected with power supply, is connected to the LED lamp of multiple mutual series connection, it is characterized in that between electric current input lead: each LED lamp two ends are also parallel with resistance respectively.
