Abstract
The utility model relates to a concentrate power supply formula LED lighting system, including a plurality of LED lamps and lanterns of mainly constituteing by LED cluster (3) and drive power supply, its characterized in that, still include an electricity connection at the drive power supply of all LED lamps and lanterns and the isolation transformer (T1) between the commercial power NULL, isolation transformer's output is connected with the drive power supply input of each LED lamps and lanterns, drive power supply includes non -isolated constant current power supply (2). This kind of concentrate power supply formula LED lighting system uses safe and reliable, can reduce overall cost when big batch uses the LED lamps and lanterns by a wide margin.
Description
Technical field
The utility model relates to LED illumination, be specifically related to a kind of centrally connected power supply formula LED illumination System, especially be applied to the LED plant illumination light fixture in warmhouse booth, the LED illumination lamp of workshop, LED illumination lamp above High-Pole Lamp etc. batch uses the occasion of LED lamp.
Background technology
At present, each LED lamp needs use constant-current supply, leak electricity for easily causing and injure the occasion of personal safety, such as: the plant lamp used in warmhouse booth, working environment hot and humid in warmhouse booth, and peasant planting process often uses instruments of labour, be also easy to touch light fixture, cause electric leakage accident.In order to keep the safety in production, this just needs to use isolated constant-current supply.But the cost of the relatively non-isolated constant-current supply of isolated constant-current supply is very high, and during intensive use in enormous quantities, construction costs can remain high.
China is at first application for a patent for invention " in large area region the central power supply system of LED illumination and driving method thereof "-publication number 104661405A and " the LED tunnel area lighting system of solar energy, wind energy or wind light mutual complementing centrally connected power supply "-publication number 101267121, disclose the centrally connected power supply of LED illumination, but be all adopt isolation separately to each LED lamp, when intensive use LED lamp in enormous quantities, construction costs can remain high.
Utility model content
The utility model technical issues that need to address are, how to provide a kind of centrally connected power supply formula LED illumination System, significantly can reduce costs and ensure the use safety of LED lamp.
Above-mentioned technical problem of the present utility model solves like this: build a kind of centrally connected power supply formula LED illumination System, comprise a plurality of LED lamp formed primarily of LED strip and driving power thereof, it is characterized in that, also comprise a driving power being connected electrically in all LED lamp and mains input between isolating transformer, the output of described isolating transformer is connected with the driving power input of each LED lamp; Described driving power comprises non-isolated constant-current supply.
The centrally connected power supply formula LED illumination System provided according to the utility model, described mains input is that 220V exchanges input, also can be other alternating voltages input meeting local technical specification.
The centrally connected power supply formula LED illumination System provided according to the utility model, described LED lamp includes, but are not limited to be 2-200.
The centrally connected power supply formula LED illumination System provided according to the utility model, described LED strip is connected in parallel on a string on described non-isolated constant-current supply output or goes here and there more.
The centrally connected power supply formula LED illumination System provided according to the utility model, described isolating transformer includes, but are not limited to be inductive-type transformer.
The centrally connected power supply formula LED illumination System provided according to the utility model, described isolating transformer includes, but are not limited to be the AC-DC transformer of switch power supply type.
The centrally connected power supply formula LED illumination System that the utility model provides, adopt high-power isolating transformer centrally connected power supply, comparatively prior art has following advantage:
1, the use safety of LED lamp is promoted;
2, significantly reduce LED illumination System cost, for the LED illumination System of about 5000W, adopt in this way, cost can reduce 40-50%.
Accompanying drawing explanation
Further the utility model is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the electrical block diagram of the centrally connected power supply formula LED illumination System that the utility model provides.
Wherein Reference numeral: the non-isolated constant-current supply of T1-isolating transformer, 2-, 3-LED go here and there.
Detailed description of the invention
As shown in Figure 1, this centrally connected power supply formula LED illumination System is used in the batch LED plant illumination in warmhouse booth: comprise input that a driving power being connected electrically in all LED lamp and civil power 220V exchange the high-power isolating transformer T1 between inputting: described isolating transformer T1 and be connected civil power 220V and exchange and input, the output of described isolating transformer T1 is connected with the driving power input of each LED lamp; Each LED lamp adopts a respective non-isolated constant-current supply 2 to drive two LED strip 3.
Certainly, the above is only preferred embodiment of the present utility model, therefore all equivalence changes of doing according to structure, feature and the flow process described in the utility model patent claim or modify, and is included in the utility model patent claim is.
