Description
Technical field
The invention belongs to direct current supply technology and field of energy-saving technology, and in particular to a kind of road LED based on direct current supply
Lamp system.
Background technique
With being skyrocketed through for national economy, LED street lamp is increasingly generallyd use by market, LED street lamp have energy conservation it is high,
The strong feature of light efficiency is current most energy-efficient road illuminating lamp, but these LED street lamps mostly use exchange way to power greatly, electricity
The alternating current that net provides is transferred to lamps and lanterns use, to carry out the conversion repeatedly of multiple alternating current and direct current, even if conversion effect
Rate reaches 90%, will also result in the power loss more than 20% or more by multiple conversions, wastes very serious.
The technical problem to be solved by the present invention is to be directed to existing market demand and the deficiencies in the prior art, a kind of base is provided
In the LED street lamp system of direct current supply, compared to traditional ac power supply system, direct current supply good, transfer efficiency with safety
High, small loss and other features.
Summary of the invention
The technical solution of the utility model is as follows:
LED street lamp system based on direct current supply, it is characterised in that: including in DC power distribution cabinet and coupled monitoring
The heart, AC network input terminal, single-lamp controller；The single-lamp controller is connected with direct-current LED lamps and lanterns.
The monitoring center is connected using wireless modes such as GPRS/CDMA with DC power distribution cabinet, and DC power distribution cabinet passes through nothing
Line mode receives the various command signals of monitoring center, and various data informations are fed back to monitoring center also by wireless mode and are carried out
Data analysis.
The ac grid voltage of the AC network input terminal input carries out AC and DC conversion through DC power distribution cabinet, will
The AC conversion of 380V is direct current of the array range in 240V-300V.
The single-lamp controller is connected by power line with DC power distribution cabinet, and DC power distribution cabinet transmits straight to single-lamp controller
Galvanic electricity pressure makes its work and transmits command signal by way of power line carrier.
The direct-current LED lamps and lanterns include LED module and DC/DC power supply, and DC power distribution cabinet is transmitted across by the DC/DC power supply
The DC voltage come is converted to DC voltage required for LED module, and the DC/DC power supply reserves intelligent dimming interface, receives
The dim signal of single-lamp controller.
Using the above scheme, the utility model not only solves problem of the existing technology, and obviously has following
Advantage: direct current transmission transfer efficiency is higher, security performance significantly improves, increases the service life of lamps and lanterns.
Detailed description of the invention
Fig. 1 is overall structure of the present invention；
Fig. 2 is DC power distribution cabinet structural schematic diagram of the present invention.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1, the utility model includes DC power distribution cabinet and coupled monitoring center, AC network input
End, single-lamp controller；The single-lamp controller is connected with direct-current LED lamps and lanterns.
As shown in Fig. 2, the DC power distribution cabinet includes rectification module and coupled defencive function module, input detection
Module, GPRS communication module, detection unit, DC distribution module；The DC distribution module is connected with output detection module；Institute
Detection unit is stated to be connected with carrier communication module.
Whole work process of the present invention is such that the alternating voltage transmitted from AC network input terminal is directly entered
DC power distribution cabinet, defencive function module built in DC power distribution cabinet and input detection module, caused by preventing because of reasons such as lightning stroke, lacunas
DC power distribution cabinet damage；Alternating current through detecting is converted into satisfactory direct current through the rectification module built in DC power distribution cabinet
Electricity is output to next stage through DC distribution module, and the output detection module and detection unit built in DC power distribution cabinet are to the straight of output
Galvanic electricity realizes on-line monitoring, guarantees system safety；GPRS communication module and carrier communication module are realized respectively to uplink and downlink
Intelligence communication.
DC voltage through DC power distribution cabinet output passes through power line transmission to the single-lamp controller of each lamp stand, and passes through list
Lamp controller finally enters direct-current LED lamps and lanterns, and the DC voltage that direct-current LED lamps and lanterns transmit DC power distribution cabinet is converted to
DC voltage required for LED module guarantees that lamps and lanterns operate normally, and single-lamp controller has dimming function, moreover it is possible to record lamps and lanterns
Operating status, and DC power distribution cabinet is fed back to by power line, data are carried out eventually by monitoring center is wirelessly transmitted to
Analysis.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
