The LED lamp strip of the utility model is added with a rectification circuit, the utility model can be suitable for the AC/DC power source, and the operation is more convenient.

Description

The LED lamp bar of adjustable-length

[technical field]

The utility model relates to a kind of structure of LED lamp bar.

[background technology]

LED possesses lot of advantages because of the optical characteristics of himself, its in service life overlength, power consumption is extremely low owing to belong to cold light source, fire safety does not have any noise, no ultraviolet radiation, so obtain more and more widely application.Present stage, led chip or LED lamp are widely used in signal and show, play dynamic graphics and text, as information demonstration, advertising etc.The LED water pipe lamp is the linear decoration light fixture that is made of PVC ambroin, copper stranded conductor and series of LED lamp; And LED lamp band is a flat belt-like, generally by evenly being connected in series led chip on the FPC, encapsulates with transparent silica gel again.Advantages such as LED water pipe lamp or lamp band are ageing-resistant owing to having, antidetonation, safety, convenient transportation are applied in the illumination and decoration of bridge, river course guardrail landscape ornamental, viaduct, skin, indoor passage, door etc.In actual applications, need adopt many LED lamp bars to connect according to concrete decorated thing, decorated occasion, the LED lamp bar that current manufacturer provides all be a fixed length, also can't carry out cutting, therefore, often is difficult to the needed length that fits like a glove.

[summary of the invention]

Main purpose of the present utility model is: the LED lamp bar that a kind of variable-length, applying flexible, adjustable-length are provided.

For achieving the above object, the utility model proposes a kind of LED lamp bar of adjustable-length, comprise FPC, LED unit, PIN socket, transparent encapsulated layer; Described LED unit is installed in parallel on described FPC, and described PIN socket is arranged at described FPC end, and described transparent encapsulated layer is coated on and becomes wire or band shape on each LED unit, the FPC; Described PIN socket has the positive-negative power port that is connected with described FPC.

The LED lamp bar of above-mentioned adjustable-length, described LED unit comprises the led chip more than or; When it comprised two or two above led chips, these two or two above led chips were connected in series.

The LED lamp bar of above-mentioned adjustable-length also comprises rectification circuit, is packaged on the described FPC, is electrically connected between the described LED unit and described PIN socket in parallel, is used for the described LED of the AC rectification rear drive unit to input.

The LED lamp bar of above-mentioned adjustable-length also comprises watertight composition, is coated on the outer surface of described FPC, transparent encapsulated layer fully.

Owing to adopted above scheme, brought following beneficial effect:

LED lamp bar of the present utility model because the connected mode that is arranged as parallel way of led chip can need be sheared it by using arbitrarily, to satisfy all lengths requirement, is used more flexible.

LED lamp bar of the present utility model has additional rectification circuit, can be suitable for the AC/DC power supply, uses more convenient.

[specific embodiment]

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment one:

Please in conjunction with Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the LED lamp bar that this is routine comprises FPC (FPC-PCB) 1, LED unit 2, PIN socket 3, transparent encapsulated layer 4, rectification circuit; Transparent encapsulated layer 4 adopts silica gel.As shown in Figure 3, each LED unit 2 is serially connected in a series connection branch road by three LEDs chips, and a plurality of LED unit 2 is connected in parallel between the positive-negative power line 11,12 of FPC; The transparent silica gel encapsulated layer is coated on and becomes a flat belt-like on each led chip, rectification circuit, the FPC, forms LED lamp bar; After applying the last layer marine glue in its immersion waterproof finishing agent, take out and solidify, outer surface forms a complete watertight composition, can strengthen the water-proof function of lamp bar.PIN socket 3 is arranged at head and the tail two ends of FPC 1, has two jacks and draws respectively and connect the positive-negative power line.

When using, can utilize 5 pairs of LED lamps of PIN plug-in unit bar to connect.Owing to is in parallel between each LED unit of lamp bar, therefore can be according to actual conditions, between being adjacent LED unit, 13 places, shearing position of FPC cut off, obtain the lamp bar length that needs.As shown in Figure 4,, can carry out rectification, make this routine LED lamp string can be directly applied for the AC/DC power supply the alternating current of 12V owing to be provided with rectification circuit.

Embodiment two:

Please refer to shown in Figure 5, the LED lamp string that this is routine, mainly be with the difference of embodiment one: the LED unit is composed in series by two LEDs chips in this example, and has cancelled rectification circuit.

The foregoing description is not to restriction of the present utility model; those skilled in the art draw various embodiments by the utility model; for example, the connection in series-parallel number of change in size of the present utility model, outer shape structure, led chip, material replacement etc. all belong to protection domain of the present utility model.
