The utility model relates to a kind of energy-saving circuit device of LED illuminating lamp, the energy-saving circuit device of the LED illuminating lamp that particularly a kind of circuit energy consumption is few.
Background technology
Ultra-high brightness LED is a kind of up-and-coming product as energy-saving lighting lamp., traditional circuit design, the current-limiting resistance part of all will connecting in circuit is as protection, and this is a power consumption part, and for a kind of energy-conserving product, this is a fly in the ointment, and existing circuit complexity, and cost is higher.
Summary of the invention
It is simple that the purpose of this utility model provides a kind of circuit, and power consumption is few and can directly insert the energy-saving circuit device of the LED illuminating lamp of electrical network.
The utility model is achieved in that a kind of energy-saving circuit device of LED illuminating lamp, comprises current limliting decompression capacitor C1, commutation diode D1, commutation diode D2, filter condenser C2, Zener diode D3 and a plurality of LED; It is characterized in that: the positive pole of the termination AC network of described current limliting decompression capacitor C1, the other end links to each other with the positive pole of commutation diode D1 and the negative pole of commutation diode D2, the positive pole of the negative pole of commutation diode D1 and filter condenser C2 links to each other with Zener diode D3 negative pole, and the negative pole of the positive pole of commutation diode D2, filter condenser C2 links to each other with the negative pole of AC network with the positive pole of Zener diode D3; Described a plurality of LED adopts and serial connection method connects, and promptly selects parallel connection earlier for use, makes the electric current of each LED and joint group unanimous on the whole, each LED and joint group is together in series again; The positive pole that LED described and that connect organizes is connected to the negative pole of Zener diode D3, and the negative pole of the LED that connects group is connected to the positive pole of Zener diode D3.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the utility model provides a kind of energy-saving circuit device of LED illuminating lamp, comprises current limliting decompression capacitor C1, commutation diode D1, commutation diode D2, filter condenser C2, Zener diode D3 and a plurality of LED; It is characterized in that: the positive pole of the termination AC network of described current limliting decompression capacitor C1, the other end links to each other with the positive pole of commutation diode D1 and the negative pole of commutation diode D2, the positive pole of the negative pole of commutation diode D1 and filter condenser C2 links to each other with Zener diode D3 negative pole, and the negative pole of the positive pole of commutation diode D2, filter condenser C2 links to each other with the negative pole of AC network with the positive pole of Zener diode D3; Because during current limliting decompression capacitor C1 initialization a very big dash current is arranged, this electric current is enough to damage LED, so will and connect a Zener diode at the LED two ends, is used for absorbing this dash current, protection LED.This Zener diode conducting voltage than LED to light voltage higher slightly, so during operate as normal, it is a no power waste.To guarantee certain brightness in addition, need the LED of some to light simultaneously, at present, because the relation of production technology, can not guarantee every LED characteristic unanimity, every electric current of lighting has difference, can not adopt series connection simply, be connected in parallel in the circuit if adopt, increase the capacity of current limliting decompression capacitor again, must add large volume and increase cost, therefore described a plurality of LED adopts and serial connection method connects, promptly select parallel connection earlier for use, make the electric current of each LED and joint group roughly consistent, again each LED and joint group are together in series; And the positive pole of the LED that connects group is connected to the negative pole of Zener diode D3, and the negative pole of the LED that connects group is connected to the positive pole of Zener diode D3.
Because powerful Zener diode is fewer on market, so as shown in Figure 2, described Zener diode D3 also can replace with a plurality of Zener diode series connection, and described a plurality of Zener diodes can be attempted by an end of LED and joint group respectively.
The rectifier bridge that commutation diode D1, D2 also can use D1a, D1b, D1c, D1d to form in the utility model substitutes as shown in Figure 3.
In order to make this device more attractive in appearance, described energy-saving circuit can be installed in the workbin [2] of illuminating lamp, and described LED can be distributed on the reflector [5] of illuminating lamp as required.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
The utility model is a capacity load, inserts electrical network, have the effect that improves power factor of electric network, and this device circuit volume is little and simple, high energy saving, and cost is low, has more considerable market prospects.
