Further, the series arm of described LED lamp group and inductance L 1 is also parallel with sustained diode 2.
Preferably, described circuit board is FR-4 epoxy resin board; And described LED lamp group comprises at least two LED lamps of series connection mutually.
Again further, described circuit board outside is also enclosed with the waterproof insulation structure being made up of PVC insulating materials embedding water-proof silica-gel.
Further, the soft plug of described PVC is Combined integrated structure semicircle and rectangle, and each corner angle of rectangle are arc.
Compared with prior art, the present invention has following beneficial effect:
(1) the present invention is from wound ac-dc converter circuit, and it and LED operating circuit are integrated in same circuit board, thereby realize the function of the direct external 220V alternating current of LED lamp bar, make it in the time that reality is used, can directly use civil power, need not remake conversion, both simplified the installation difficulty of LED lamp bar, improve ease of use, save again the low-voltage dc power supply of prior art, reduce product cost, have advantages of simple in structure, with low costly, and can greatly reduce fault rate, be applicable to very much promoting the use of.
(2) because advertisement LED lamp box is located at open air mostly, therefore need to consider the impact of weather on it, in prior art, electronic device need to be considered the problems such as waterproof, protection against the tide, fire prevention, thereby must use expensive direct current waterproof power supply, the present invention is directed to this problem in waterproof insulation structure of ac-dc converter circuit outer wrapping, adopt the lower PVC embedding silica gel of price to be made, so both realized insulative water-proof function, maintenance workload and maintenance cost are reduced, reduce again production cost, killed two birds with one stone.
(3) not of uniform size the causing of the present invention's LED lamp box in actual applications causes the difference of demand electrical power value larger, therefore in AC/DC change-over circuit for making LED lamp pearl luminous evenly, what adopt is constant current chip but not current regulator diode makes its voltage scope of application wider, and adaptive capacity is higher.
(4) after the LED lamp pearl from damaging, cause the situation of whole LED lamp box luminance nonuniformity to occur for preventing, LED module adopts series connection form to connect, after a LED lamp pearl bright light loses efficacy, all LED lamp pearls quit work, for advertising field, so all extinguish than part and extinguish better, can avoid part to extinguish the negative effect bringing.
(5) circuit that the present invention adopts is simplified reliably, take a rectifying device as core, 220V alternating current direct is switched through to the direct current for 240V, supply with many LED lamps of series connection mutually, and in LED operating circuit, access a sustained diode 2, thereby can effectively guarantee that LED, for a long time in constant current state, guarantees the luminous uniformity.
(6) the present invention adopts the lamp bar shell that PC groove, PC Transparent lamp shade, the soft plug of PVC and PC protective cover combine, and it has good sealing effectiveness, can further improve waterproof and dustproof, insulation effect, and durable in use, and service life is extremely long.
(7) the soft plug of PVC of the present invention adopts the shape of semicircle and rectangle combination, and corner angle are all designed to arcuate structure, not only good looking appearance, and can farthest reduce LED lamp bar moving, the wearing and tearing of installing, easily occurring in use, maintenance process, make it can keep for a long time reset condition, thereby increase the service life, reduce maintenance, change probability, improve practical value.
