The Chinese patent Granted publication number is CN201037608Y, Granted publication day is that the utility model patent on March 19th, 2008 discloses a kind of LED electricity-saving lamp device, comprise rectification circuit unit, filter circuit unit and LED lamp string, voltage clamp to the first class of protection circuit unit and the switch constant-current circuit unit of predetermined voltage; Described first class of protection circuit unit is connected in parallel in the circuit power end; source current flows into LED lamp string behind the rectification of rectification circuit unit, filter circuit unit filtering; LED lamp string and switch constant-current circuit units in series connect to form series loop, and series loop and rectification circuit unit, filter circuit unit are connected in parallel.Though this utility model can avoid the LED lamp by moment the surge current punch through damage, effectively prolong service life of LED lamp, but its complex structure, need to use a lot of electronic components, cost is higher, and its employed bleeder resistance, current-limiting resistance and electrochemical capacitor leak electricity, waste electric energy easily.In addition, electrochemical capacitor not only damages, easily influences the normal use of whole energy-saving circuit easily, and along with the increase of LED lamp power, the capacity of electrochemical capacitor, withstand voltage and volume will obviously increase, and the manufacturing cost of this kind LED lamp also can increase thereupon.
Summary of the invention
The purpose of this utility model is to overcome defective that complex structure, electronic component are fragile, manufacturing cost is more expensive and the problem that exists in the prior art, and a kind of simple in structure, electronic component is not fragile, manufacturing cost is lower LED electricity-saving lamp device is provided.
For realizing above purpose, technical solution of the present utility model is: a kind of LED electricity-saving lamp device, comprise electric capacity, No. two electric capacity and LED lamp string, and a described electric capacity and No. two capacitances in series, a described electric capacity is by LED lamp string and No. two capacitances in series.
Also include bridge rectifier in the described LED electricity-saving lamp device, the power connection on the bridge rectifier is connected with an electric capacity, No. two electric capacity respectively, and the load connector on the bridge rectifier is connected with LED lamp string.
Described LED lamp string comprises last LED lamp string in parallel and following LED lamp string, and it is opposite with the polarity of following LED lamp string to go up LED lamp string.
Compared with prior art, the beneficial effects of the utility model are:
1. only comprise an electric capacity, No. two electric capacity, LED lamp string and bridge rectifiers owing in a kind of LED electricity-saving lamp of the utility model device, simple in structure, and be not easy to damage, can effectively reduce fault rate.Therefore simple in structure, the difficult breaking-up of the present utility model.
2. because the main design of a kind of LED electricity-saving lamp of the utility model device is to be connected in series with LED lamp string between two electric capacity, in actual applications, both can between LED lamp string and two electric capacity, a bridge rectifier be set, also can not use bridge rectifier, and be designed to LED lamp string parallel with one another, opposite polarity LED lamp string and the following LED lamp string gone up, not only can guarantee the normal use of LED electricity-saving lamp device, and can effectively avoid the generation of surge current, save a large amount of flimsy electronic components, improve the security of device, prolonged the service life of device.Therefore security of the present utility model is higher, service life is longer.
Description of drawings
Fig. 1 is basic principle figure of the present utility model.
Fig. 2 is the circuit diagram of embodiment 1 of the present utility model.
Fig. 3 is the circuit diagram of embodiment 2 of the present utility model.
Among the figure: 1, No. two electric capacity 2 of an electric capacity, LED lamp string 3, last LED lamp string 31, following LED lamp string 32, bridge rectifier 4, big resistance 5.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is described in further detail
Referring to Fig. 1-Fig. 3, a kind of LED electricity-saving lamp device comprises electric capacity 1, No. two electric capacity 2 and LED lamp string 3, and a described electric capacity 1 is connected with No. two electric capacity 2, and a described electric capacity 1 passes through LED lamp string 3 and connects with No. two electric capacity 2.
Also include bridge rectifier 4 in the described LED electricity-saving lamp device, the power connection on the bridge rectifier 4 is connected with electric capacity 1, No. two electric capacity 2 respectively, and the load connector on the bridge rectifier 4 is connected with LED lamp string 3.
