For example Granted publication number is the patent of invention of CN 101846248 B again, a kind of 360 ° of luminous self-cooling LED fluorescent lamp type lamp fittings are disclosed, it comprises fluorescent tube, be fixed on the external power source connector of lamp tube ends, internal electric source converter, radiator, LED light source, internal connector, external power source connector wherein, radiator, internal electric source converter, LED light source, internal connector, fluorescent tube is by connecting and composing light fixture, wherein, described radiator is one to be arranged on the body with holes in the middle of fluorescent tube, and be positioned in fluorescent tube inner chamber by being arranged on the internal connector at two ends, described multiple LED light sources are arranged on the outer cylinder of porous tubular body regularly according to 120 ° of arc spacing distances, and form power supply circuits by the internal electric source converter and the external power source connector that are arranged on radiator end, described external power source connector is provided with and connects inside and outside air vent hole, form thus from 360 ° of luminous LED fluorescent lamp type lamp fittings of heat radiation.

From above-mentioned patent, everyly to obtain 360 ° of luminous LED light fixtures, must be through other somewhat complex design, need multiple LED light sources to be installed on to realize in special structure 360 ° luminous, its complex structure, cost is high.

Utility model content

Therefore, for above-mentioned problem, the utility model proposes the luminous LED device of box-like 360 degree of a kind of Double-face adhesive, the improvement of novelty current LED chip structure, realize 360 ° luminous, and simple in structure, with low cost.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is, the luminous LED device of box-like 360 degree of a kind of Double-face adhesive, comprise two supports that arrange in opposite directions, support is provided with the substrate for fixed support LED illuminating module, the both positive and negative polarity of adjacent two substrates arranges on the contrary, and the both positive and negative polarity of LED illuminating module is drawn and formed pin by gold thread, and described support covering is equipped with moulding glue.

Further, described LED illuminating module comprises the LED chip that several are connected in series, and preferred, the both positive and negative polarity of each LED chip is all towards identical.In the time of die bond bonding wire, the both positive and negative polarity head and the tail serial connection of adjacent LED chip.

Preferably, described moulding rubber seal fills after whole support, forms the rotational symmetry structure take support axis as axis, and this rotational symmetry structure can be cylindrical structure, also in the middle of can being, be cylindrical structure, two ends be the conical structures that are connected with this cylindrical structure.

The proposition such scheme of the utility model novelty, forms the luminous LED device of 360 degree by above-mentioned two sides support laminating, realized 360 ° luminous, and simple in structure, with low cost.
