Further, described LED group is also parallel with sustained diode 2 with the series arm of inductance L1.
Preferably, described circuit board is FR-4 epoxy resin board；And described LED group includes the LED that at least two is serially connected.
Yet further, the waterproof insulation structure being made up of PVC insulant embedding water-proof silica-gel also it is enclosed with outside described circuit board.
Further, the soft plug of described PVC is the semicircle Combined integrated structure with rectangle, and each corner angle of rectangle are arc.
Compared with prior art, the method have the advantages that
(1) present invention is from creating ac-dc converter circuit, and it and LED operation circuit are integrated in same circuit board, it is achieved thereby that the function of the direct external 220V alternating current of LED lamp bar, it is enable directly to use civil power when actually used, conversion need not be remake, both the installation difficulty of LED lamp bar had been simplified, improve ease of use, save again the low-voltage dc power supply of prior art, reduce product cost, there is simple in construction, advantage with low cost, and fault rate can be greatly reduced, be especially suitable for and promote the use of.
(2) owing to advertisement LED case is located at open air mostly, it is thus desirable to consider the weather impact on it, in prior art, electronic device needs to consider the problems such as waterproof, protection against the tide, fire prevention, thus expensive direct current waterproof power supply must be used, the present invention is directed to this problem in one waterproof insulation structure of ac-dc converter circuit outer wrapping, the PVC embedding silica gel adopting price relatively low is made, so both achieved insulative water-proof function, decrease maintenance workload and maintenance cost, reduce again production cost, kill two birds with one stone.
(3) not of uniform size the causing of present invention LED case in actual applications causes that the difference of demand electrical power value is bigger, therefore for making LED lamp bead luminous uniformly in AC/DC change-over circuit, what adopt is constant current chip but not current regulator diode so that it is the voltage scope of application is wider, and adaptive capacity is higher.
(4) for preventing the LEDs lamp bead from causing that the situation of whole LED case luminance nonuniformity occurs after damaging, LED module adopts cascade to connect, after a LED lamp bead bright light loses efficacy, all LED lamp bead quit work, for advertising field, so all extinguish better than local is extinguished, it is possible to avoid locally extinguishing the negative effect brought.
(5) circuit that the present invention adopts is simplified reliably, with a rectifying device for core, 220V alternating current direct is switched through for 240V unidirectional current, supply many LED being serially connected, and in LED operation circuit, access a sustained diode 2, such that it is able to be effectively ensured LED to be chronically at constant current state, it is ensured that the luminous uniformity.
(6) 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, it is possible to improve waterproof and dustproof, insulation effect further, and durable in use, and service life is extremely long.
(7) the soft plug of the PVC of the present invention adopts semicircle and rectangle combination shape, and corner angle are all designed to arcuate structure, not only good looking appearance, and can farthest reduce LED lamp bar moving, the abrasion installing, use, easily occur in maintenance process, make it can keep initial condition for a long time, thus increasing the service life, reducing maintenance, changing probability, improving practical value.
