The specific embodiment

With reference to accompanying drawing the preferred embodiment of the utility model is described below.

In conjunction with referring to Fig. 3 and shown in Figure 4; The utility model embodiment provides a kind of LED lamp band; Comprise heart yearn 1, LED lamp string 2 and plastic body 3, said LED lamp string 2 comprises that through connecting line 21 a plurality of led light sources 22 in succession said heart yearn 1 comprises power line 11 and a plurality of punchings 12; Said a plurality of led light source 22 correspondences are installed in said a plurality of punching 12, and said connecting line 21 is connected on the said power line 11;

Said LED lamp band also comprises in order to keep said LED lamp string 2 photochromic conforming lids to be with 4; Said lid with 4 cover said a plurality of led light sources 22 of said LED lamp string 2 the surface, said plastic body 3 is coated on said heart yearn 1, said LED lamp string 2 and said lid with 4 periphery.

Heart yearn 1 is the strip belt body structure that the cross section is the square shape, and it passes through the moulding of plastic cement expressing technique by plastic material.The pre-buried setting at least two strip metal power lines 11 in the inside of heart yearn 1, its effect are to be connected with 2 conductings of LED lamp string.In the present embodiment, metallic power line 11 is set to two, is arranged on the two ends of heart yearn 1 inside along the bearing of trend of heart yearn 1.Evenly offer a plurality of punchings 12 at the middle part of heart yearn 1, its effect is a plurality of led light sources 22 of laying LED lamp string 2.In the present embodiment, punching 12 side's of being shapes of on heart yearn 1, offering are positioned at the centre of above-mentioned two metallic power lines 1, and the spacing that the size of each punching 12 and a plurality of punching are 12 is provided with equal.That is to say that punching 12 equidistance are evenly offered, its be for and the spacing of 22 of led light sources suitable, be convenient to the Fast Installation of led light source 22 and heart yearn 1.

It is understandable that; Offering the shape and the spacing between a plurality of punching 12 of punching 12 on the heart yearn 1 can adjust according to the size of a plurality of led light sources 22 on the LED lamp string 2 of reality and mutual lamp distance; To satisfy the Fast Installation of LED lamp string 2, its shape and the position of offering do not influence the implementation result of the utility model.

LED lamp string 2 comprises through connecting line 21 a plurality of led light sources 22 in succession.In the present embodiment, the spacing that the spacing that a plurality of led light sources are 22 is provided with a plurality of punchings 12 that equate and offer with above-mentioned heart yearn 1 is provided with identical.During enforcement, also have some resistance that are connected in series with led light source 22 (figure does not show) on the LED lamp string 2, these series resistors can play the effect of current limliting.During assembling, can earlier a plurality of led light sources 22 of LED lamp string 2 be inserted in the punching 12 of above-mentioned heart yearn 1 successively, owing to the corresponding coupling in position that position and a plurality of led light sources 22 of a plurality of punchings 12 are offered, both can position easily.And then, the connecting line 21 of led light source 22 head and the tail is connected on the pre-buried metallic power line 11 of above-mentioned heart yearn 1.Like this, accomplished installing and fixing of LED lamp string 2 and heart yearn 1.The heart yearn 1 that LED lamp string 2 is installed can reverse along the direction of its extension.

Lid is with 4 to be to be used to keep LED lamp string 2 photochromic conforming structural members, and the shape of its shape and heart yearn 1 is roughly the same, also is that the cross section is the square shape and has the strip belt body of certain-length.In the present embodiment, lid is provided with identical with 4 the sectional dimension and the sectional dimension of heart yearn 1, and its side surface that covers heart yearn 1 will be installed in a plurality of led light sources 22 coverings in a plurality of punchings 12.Further, because a plurality of led light sources 22 of LED lamp string 2 are arranged in the punching 12 of heart yearn 1, above-mentioned lid covers on the light-emitting area of a plurality of led light sources 22 with 4.

Preferably, lid is with 4 to be to be processed by light transmissive material, and for example: lid is with 4 can select printing opacity plastic cover band for use, and the effect of using transparent material is on the basis that keeps LED lamp string 2 luminous photochromic unanimities, reduces the influence to LED lamp string 2 luminous intensities as much as possible.During practical implementation; Lid is with 4 can be by PC (Polycarbonate, Merlon), PVC (Polyvinylchloride, polyvinyl chloride), ABS resin (Acrylonitrile Butadiene Styrene; Acrylonitrile-styrene-butadiene copolymer) or PS (Polystyrene; Polystyrene) etc. material is processed, and these materials not only can keep the penetrability of light, and are easy to control cost.

Preferred embodiment, the gauge of printing opacity plastic cover band is more than or equal to 0.05mm.This gauge can be controlled luminous photochromic the reaching unanimity of LED lamp string 2 to the full extent, this LED product can be applied in have the occasion that requires than luminous.

Plastic body 3 coatings are arranged on heart yearn 1, the LED lamp string 2 after above-mentioned the installing and fixing and cover the periphery with 4; It also is to be processed by light transmissive material, and plastic body 3 forms the plastic cement crust with waterproof and dustproof and moisture-proof role through the outside that plastic rubber shaping technology is coated on above-mentioned assembly structure.During enforcement,, do not need other supplementary structures just can moulding, can simplify technological process, be beneficial to the product intensivization development, energy-conserving and environment-protective because this layer plastic cement crust directly is coated on heart yearn 1, LED lamp string 2 and lid with 4 periphery.

In other embodiments of the utility model; Lid is not limited to the measure-alike mode of above-mentioned and chip 1 with 4 size; It also can be applicable under sectional dimension and the unequal situation of chip sectional dimension; As long as satisfy this lid with 4 cover a plurality of led light sources 22 the surface, the light that a plurality of led light sources 22 are launched reaches certain photochromic requirement and gets final product.

The LED lamp band of the utility model; Owing to comprise the perspex lid band that covers a plurality of led light sources surface; The light that led light source sends sees through and reaches unanimity after perspex lid band penetrates, and can reduce the luminous otherness of lamp band, has promoted the whole luminescent properties of LED lamp band.

Above disclosedly be merely the utility model preferred embodiment, can not limit the interest field of the utility model certainly with this, the equivalent variations of therefore being done according to the utility model claim still belongs to the scope that the utility model is contained.
