Description

A kind of flexible light band

Technical field

The utility model relates to a kind of ornament lamp, refers in particular to a kind of flexible light band.

Background technology

Nowadays in the various decorative lightings of indoor and outdoor the application of lamp band more and more widely, as the profile at place, indoor corner decorate, outdoor building body is decorated and various advertising signboard on, the application of lamp band is seen everywhere.But existing lamp band generally all is to adopt flexible PCB to connect, and the Copper Foil of silk-screen is very thin on the flexible PCB, can not adopt high pressure to drive, and drives so existing lamp band must be equipped with the Switching Power Supply step-down.So existing lamp band generally can only be below the 30V, limited length, simultaneously the cost of Switching Power Supply has accounted for 40% of whole lamp band cost nearly, and production cost is very high.If the Decorative lamp belt that actual needs is long then needs to connect successively a plurality of lamp tape cells, inconvenience is installed, and cost is very high.The manufacturing cost of this conventional lights band is higher, is not suitable for the indoor and outdoor decorative lighting of long distance, big face.So people thirst for obtaining a kind of lamp mark modest ability, flexible light band that cost of manufacture is cheap always.

The utility model content

Have many technological deficiencies such as size is short, cost of manufacture is high, inapplicable high drive at flexible light band of the prior art, the purpose of this utility model is to provide that a kind of cost of manufacture is cheap, high drive, flexible light band that the lamp body size is long.

In order to reach the technical scheme that above-mentioned technical purpose the utility model takes is a kind of flexible light band, comprise by first bonding jumper lamp string that a plurality of LED and resistive element form that is connected in series, described lamp string both sides are provided with as second, third bonding jumper of main power line, the head end of described lamp string and tail end are electrically connected with described second, third bonding jumper respectively, and a flexible and transparent clad coats above-mentioned lamp string and second, third bonding jumper; The head end of described flexible and transparent clad and tail end also are provided with attaching plug and the power supply extension connector that is electrically connected with described second, third bonding jumper, and the rated voltage sum of described a plurality of LED and resistance equals the input voltage of lamp band.

Because the utility model adopts bonding jumper to replace traditional flexible PCB, makes flexible light band of the present utility model go for high drive.The number of illuminator is reasonably allocated according to the input voltage of lamp tape input end simultaneously, saved the Switching Power Supply in the conventional lights band, reduce the manufacturing cost of lamp band significantly, and prolonged the length of lamp band, solved the short technological deficiency of lamp body size in the prior art.

Preferably, described flexible and transparent clad one side backlight is provided with one deck adhered layer.

Preferably, the voltage of described power input is 120V or 220V.

Preferably, the described flexible and transparent clad plastic layer that is flexible and transparent.

Preferably, described LED is ACLED.

Preferably, also be in series with rectifier between described power supply connector and the lamp string.

Preferably, described LED is direct insertion or adopting surface mounted LED.

Preferably, described first metal conductive strips, second metal conductive strips and the 3rd metal conductive strips are that a cross section is circular or oval-shaped metal conductive wire.

The specific embodiment

For further detailed elaboration design concept of the present utility model, be elaborated below in conjunction with accompanying drawing.

Shown in Fig. 1, Fig. 2 and figure A-A, the utility model discloses a kind of flexible light band, comprise by the first bonding jumper 2 lamp string that a plurality of LED1 and resistive element 11 form that is connected in series, described lamp string both sides are provided with as main power line second bonding jumper 3 and the 3rd bonding jumper 4, the head end of described lamp string and tail end are electrically connected with second bonding jumper 3 and the 3rd bonding jumper 4 respectively, and a flexible and transparent clad 5 coats above-mentioned lamp string, second bonding jumper 3 and the 3rd bonding jumper 4; The head end of described flexible and transparent clad and tail end also are provided with attaching plug 8 and the power supply extension connector 9 that is electrically connected with described second bonding jumper 3 and the 3rd bonding jumper 4, and the rated voltage sum of described a plurality of LED1 and resistance 11 equals the input voltage of lamp band.Power supply extension connector 9 can be that female joint is male joint also, is connected with the charged gas of the lamp of next unit with convenient.

Because the utility model adopts bonding jumper to replace traditional flexible PCB, makes flexible light band of the present utility model go for high drive.The number of illuminator is reasonably allocated according to the input voltage of lamp tape input end simultaneously, saved the expensive Switching Power Supply in the conventional lights band, reduced the manufacturing cost of lamp band significantly, and the length that has prolonged the lamp band, solved the short technological deficiency of lamp body size in the prior art.

As scheme A-A and shown in Figure 3, and the installation of the utility model flexible light band for convenience, the utility model also is provided with one deck adhered layer 7 (promptly in lamp band one side backlight), conveniently to make the installation of lamp band in flexible and transparent clad one side backlight.Adhered layer 7 comprises colloid layer 71 and colloid protective layer 72, in use colloid protective layer 72 is torn, and can directly wait on the installation material fixing at body of wall.

Input voltage of the present utility model is the civil power of 120V or 220V, and the number of LED1 can be adjusted according to the actual input voltage of lamp band.The rated voltage sum of the rated voltage of a plurality of LED1 and resistance 11 equals the input voltage of lamp band.Flexible and transparent clad 5 of the present utility model is the plastic layer of flexible and transparent.

LED1 of the present utility model can be direct insertion LED or adopting surface mounted LED, and the adopting surface mounted LED that preferred size is less also can the less side view LED of preferred dimension.

The utility model also is in series with a rectifier 10 between attaching plug 8 and lamp string, realize direct current supply by rectifier 10; Certainly also can directly adopt direct current supply, the LED1 of this moment preferably adopts ACLED;

Because the solder joint between first pad 6 bonding jumper 2 and LED1 is too big, might make when the lamp band bears than macrobending stress that solder joint is stressed to come off, so the technical scheme of this practicality also can be done following optimization; First, second, third metal conductive strips can adopt the less conductor wire of cross-sectional area, is circular or oval-shaped metal conductive wire or the like as cross section.The cross section that reduces metal conductive strips can make the pad 6 of LED1 and the contact point of first metal conductive strips 2 reduce, thereby can make the lamp band be more prone to crooked, as Fig. 4, shown in Figure 5.

The above only with convenient explanation the utility model, or else breaks away from the creation spirit category of the present utility model, and any simple modification that those skilled in the art did of knowing this technology still belongs to protection domain of the present utility model with distortion.
