Abstract
The utility model relates to an LED lighting circuit, belonging to the field of LED application, which mainly comprises LED lamps and voltage stabilizing tubes and is characterized in that one LED lamp and one voltage stabilizing tube are connected in parallel to form one lighting unit and two or more lighting units are connected together in series. N lighting units can be connected together in series according to the need to form LED lighting lamps of different specifications and different powers. The utility model has the advantages that the normal operation of the entire circuit is not affected when individual LED lamps are damaged, the hold time is long, the maintenance quantity is small, the lighting effect is good and the over-voltage, and the lightning and the static electricity areprevented.
Description
Technical field
The utility model belongs to the application of LED, particularly a kind of connection circuit of LED lamp.
Background technology
LED is a kind of light emitting diode, and the LED Lantern Festival electricity that is made is up to more than 80%, and the life-span is more than 10 times of common fluorescent tube, is a kind of semi-conductor electricity light source of environmental type, and light is soft, spectroscopic pure.Present LED lighting lamp circuit is divided into two kinds of tandem type and parallel connection types, when adopting tandem type, if wherein a LED lamp is damaged and will be caused whole circuit not work; When adopting parallel connection type, more because of LED quantity, total current can be bigger, and the constant current regulated power supply load increases, thereby raises the cost.
The innovation and creation content
The purpose of this utility model is to provide a kind of LED lighting circuit of mixed type.
The utility model is achieved in that
The LED lighting circuit mainly comprises LED lamp and voltage-stabiliser tube, it is characterized in that: a LED lamp and a voltage-stabiliser tube compose in parallel one group of lighting unit, and one group of above lighting unit is cascaded.
Also be in series with a resistance on every group the voltage-stabiliser tube.
After the utility model adopts said structure, can be connected into n group lighting unit arbitrarily, the LED illuminating lamp of forming the different size different capacity, the damage of LED lamp does not influence the operate as normal of entire circuit in the lighting unit, has the length of holding time, the effect that maintenance is little, good illumination effect, superpressure preventing, anti-thunderbolt static.
Description of drawings
Accompanying drawing is circuit theory diagrams of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
The utility model is a kind of LED lighting circuit, and as shown in drawings, LED lamp D1 and voltage-stabiliser tube W1 compose in parallel first group of lighting unit, and the voltage-stabiliser tube W1 of this lighting unit goes up resistance R 1 of series connection; LED lamp D2 and voltage-stabiliser tube W2 compose in parallel second group of lighting unit, and the voltage-stabiliser tube W2 of this lighting unit goes up resistance R 2 of series connection; And the like form n group lighting unit, n group lighting unit is cascaded successively, forms the LED illuminating lamp of power demand, links to each other with external power source again.
The quantity of lighting unit is decided according to required specification power, form 5W LED lamp as five groups of lighting units, ten groups of lighting units are formed 10W LED lamp, and the like, can form 15W, 20W, 25W, 30W, 50W, 60W, 70W, 80W, 90W, 100W, 120W constant power LED illuminating lamp.
Claims (2)
1, LED lighting circuit mainly comprises LED lamp and voltage-stabiliser tube, it is characterized in that: a LED lamp and a voltage-stabiliser tube compose in parallel one group of lighting unit, and one group of above lighting unit is cascaded.
2, LED lighting circuit according to claim 1 is characterized in that: also be in series with a resistance on every group the voltage-stabiliser tube.
