Abstract

The utility model discloses an LED decorative lamp, and relates to an LED colored lamp string adopting triodes for open circuit protection. The LED colored lamp string comprises a bridge rectifier circuit, a power supply and a plurality of LED colored lamps which are connected in series, wherein each LED colored lamp comprises a lamp holder and two pins; the two ends of each LED colored lamp are connected in parallel with one triode, the emitting electrode of the triode corresponds to the positive electrode of the LED colored lamp, and the collecting electrode thereof corresponds to the negative electrode of the LED colored lamp. The LED colored lamp string adopting the triodes for open circuit protection, which is provided by the utility model, introduces the triodes as the bypass device, so that normal operation of the whole lamp string can be ensured regardless of damage or falling off of one lamp cap in any position in the lamp string; no current flows through the triodes when the lamp caps of the lamp string are in normal operation, so that power consumption is reduced, energy is saved, and attractiveness and practicability are realized; meanwhile, compared with a traditional lamp string in parallel connection, production cost is greatly reduced, resources are saved, and waste is reduced.

Description

Adopt triode to make the LED Color lamp string of open-circuit-protection

Technical field

The utility model relates to LED ornament lamp lighting field, specifically, relates to a kind of LED Color lamp string that adopts triode to make open-circuit-protection.

Background technology

development along with society, the progress of science and technology, various ornament lamps flood the market, become beautiful landscape one, home decoration, the city lighting engineering, various street lamps, various recreations place, billboard, electronic product, suspension members etc. all can arrange the various decorations of doing something for the occasion, wherein, the most welcome with the LED lamp, it has advantages of has incomparable with traditional incandescent lamp, volume is little, power consumption is low, long service life, high brightness is low in calories, environmental protection, sturdy and durable, beautiful in colour etc., can realize the multiple variation of color, can not only play illuminating effect, can also play decoration function, give pleasing sensation, can increase many celebrating atmosphere, just because of this, various LED lamp strings appear on the market again and again.

In the market, the LED Color lamp string has in parallel and two connected modes of series connection.As shown in Figure 1, the existing LED Color lamp string 100 that is connected in series mode ", by a plurality of LED lamps 1 " be connected in series and form, when LED Color lamp string 100 " in any one LED lamp 1 " damage or come off, whole LED Color lamp string 100 " all can extinguish; and the mode of being connected in parallel can overcome above-mentioned shortcoming, but cost is too high, and also having a kind of is in being connected in series the lamp string of mode; each lamp holder resistance in parallel; after lamp holder damages or comes off, and resistance can replace lamp holder, the lamp string is worked on do not extinguish.But the shortcoming of this mode is when lamp holder works, and resistance simultaneously also in place in circuit, can consume the part electric energy, very not environmental protection.

The utility model content

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and a kind of high stable LED Color lamp string that adopts triode to make open-circuit-protection of providing.

The technical scheme that the prior art problem that solves the utility model adopts is: a kind of LED Color lamp string that adopts triode to make open-circuit-protection; comprise bridge rectifier, power supply and a plurality of LED color lamp that is connected in series; described LED color lamp comprises lamp socket and two pins; triode in parallel with it at the two ends of described each LED color lamp; the positive pole of the corresponding described LED color lamp of the emitter stage of described triode, the negative pole of the corresponding described LED color lamp of colelctor electrode.

The below is further elaborated above technical scheme:

Further, described triode is connected between described two pins.

Further, described triode is packaged in described lamp socket.

The beneficial effects of the utility model are:

The first, the utility model adopts triode to make the LED Color lamp string of open-circuit-protection; introduce triode as shunting device; no matter in the lamp string, the lamp holder of any position damages or comes off; all can guarantee whole lamp string normal operation; and the lamp holder of lamp string when normal operation; there is no the electric current triode of flowing through, can reduce power consumption, energy-saving and environmental protection.

The second, the utility model adopts triode to make the LED Color lamp string of open-circuit-protection, triode in parallel between two pins of prior lamp holder, and within triode is arranged on lamp socket, both artistic and practical.

Three, the utility model adopts triode to make the LED Color lamp string of open-circuit-protection, not only can overcome the shortcoming of traditional serial-connection light string, with respect to the tradition lamp string that is connected in parallel, greatly reduces production costs simultaneously, economizes on resources, and has reduced unnecessary waste.

Description of drawings

Fig. 1 is the electrical block diagram of LED Color lamp string in prior art;

Fig. 2 adopts triode to make the electrical block diagram of the LED Color lamp string of open-circuit-protection in this new embodiment.

The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.

The specific embodiment

Describe the technical solution of the utility model in detail below with reference to drawings and the specific embodiments, so as clearer, understand invention essence of the present utility model intuitively.

As shown in Figure 2; make the electrical block diagram of the LED Color lamp string 100 of open-circuit-protection for adopting triode in this new embodiment; adopt triode to make the LED Color lamp string 100 of open-circuit-protection; comprise bridge rectifier, power supply and a plurality of LED color lamp 1 that is connected in series; LED color lamp 1 comprises lamp socket and two pins; triode 2 in parallel with it at the two ends of each LED color lamp 1, the positive pole of the corresponding described LED color lamp 1 of the emitter stage of triode 2, the negative pole of the corresponding LED color lamp 1 of colelctor electrode.Triode 2 can also be connected between two pins, is arranged in parallel with lamp socket, and is convenient to attractive in appearancely, and triode 2 is packaged in lamp socket.When switching on power, when the lamp holder of LED Color lamp string 100 works, do not have the electric current triode 2 of flowing through, by this, can reduce the consumption of electric energy, save and environmental protection, the lamp holder of any position damages or comes off in LED Color lamp string 100, triode 2 can play conducting again, so can guarantee whole LED Color lamp string 100 normal operations, and can wholely not extinguish.

The above is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
