The specific embodiment

Below in conjunction with specific embodiment, the utility model is done progressive explanation.Should be understood that following examples are only for explanation the utility model but not for limiting scope of the present utility model.

Embodiment 1

Fig. 1 is floor map of the present utility model, and Fig. 2 is side structure enlarged drawing of the present utility model.As depicted in figs. 1 and 2, a kind of line style led light source is 3-tier architecture, is respectively: reflective sheeting 100, aluminium foil layer 200 and bond plies 300, superimposed from top to bottom successively, the surface of its superiors is reflective sheeting 100.

As shown in Figure 1; reflective sheeting 100 is provided with a plurality of loopholes 110; led chip 220 and formed the light source portion 250 of projection by the diaphragm 240 that transparent adhesive tape is varied to; and be located in the loophole 110; fluorescent material has also been spread on led chip 220 surfaces; the diaphragm 240 that fluorescent material and transparent adhesive tape form increases the light transmission of led light source, also can select different fluorescent material to come the different color of conversion simultaneously.

From Fig. 2 we as can be seen, very thin of the utility model, conventional art adopts be the aluminium foil layer of 1mm thickness as its circuit board, the utility model then is to adopt 3-tier architecture, thickness is less than 0.5mm.Such benefit has 2 points:

One, increases toughness, save material.Be the problems of the common thinking of many businessmans if reduce production costs, starting point tends to select the materials from material to start with, but line style LED lamp bar itself is with regard to the thickness because of easily broken and very difficult minimizing aluminium foil, but the utility model adopts 3-tier architecture, to compare toughness higher with 1 layer of simple aluminium foil layer 200, and other two-layer materials no longer are metals, are difficult to fracture.

Two, can bring into play himself different characteristic by 3 layers of different medium, reflective sheeting 100 is outstanding light-concentrating materials, and the thermal hole 310 of bond plies plays heat sink effect, and the insulated with material heat radiation of itself can be derived heat of the present utility model.

Fig. 3 is the reflective sheeting floor map.As shown in Figure 3, reflective sheeting 100 is list structure, is provided with the fixing loophole 110 of spacing above.

Fig. 4 is the aluminium foil layer floor map.As shown in Figure 4, aluminium foil layer 200 comprises: aluminum foil strip 210, led chip 220 and connecting line 230.The utility model is that a plurality of led chip 220 usefulness transparent adhesive tapes are adhered on the aluminum foil strip 210, led chip 220 is installed on the aluminum foil strip 260 with the distance of the about 0.3mm of spacing, be with holes on the aluminum foil strip 260, connecting line 230 interts from these apertures and is connected with the both positive and negative polarity of led chip 220 simultaneously, finish routing work, by connecting line 230 led chip 220 is coupled together then and form the connection in series-parallel connection.

Fig. 5 is the bond plies floor map.As shown in Figure 5, bond plies 300 is for list structure and be provided with thermal hole 310, and it simultaneously is that cementing layer 320 is bonding with aluminium foil layer 200, and bond plies 300 another sides are release liners 330.What the utility model circuit board adopted is aluminum foil strip 210, and aluminum foil strip 210 heat-sinking capabilities are strong, can effectively promote heat dispersion.Bond plies 300 is posted in the below of aluminum foil strip 210 simultaneously, this 300 bodies of bond plies can heat conduction outside, the thermal hole 310 that also is provided with, can allow aluminum foil strip 210 contact with air and accelerate heat radiation, simultaneously can also in thermal hole 310, add heat-conducting silicone grease according to actual conditions, heat-conducting silicone grease is extraordinary Heat Conduction Material, and heat-sinking capability of the present utility model is more stepped to a new level.

The number of loophole 110, led chip 220 and thermal hole 310 is corresponding one by one, and overlaps each other.

Embodiment 2:

Fig. 6 is aluminium foil layer floor map among the embodiment 2.As shown in Figure 6, led chip 220 of the present utility model can also be connected in series except can connection in series-parallel connecting.After employing is connected in series, then can not adopt aluminum foil strip 210 to make as a whole method.Therefore aluminium foil layer 200 will by a piece independently aluminium foil 260 forms, but not the rectangular strip among the embodiment 1 is constructed.A plurality of led chip 220 usefulness transparent adhesive tapes are adhered on the aluminium foil 260 of quantity correspondence, are keeping the spacing of about 0.3mm between the aluminium foil 260, by connecting line 230 led chip 220 are coupled together to form then to be connected in series.Remaining part is with embodiment 1.

More than the specific embodiment of the present utility model is illustrated, but the utility model is as limit, only otherwise break away from aim of the present utility model, the utility model can also have various variations.
