Description

The LED power supply
Technical field
The utility model belongs to the LED field, particularly a kind of LED power supply.
Background technology
Now society is increasing to the demand of the energy, and it is more and more higher to have impelled the efficient of power consumption equipment to require, and illumination also requires higher efficient as the large electricity consumer, thus LED since its efficiently luminous efficiency come into vogue; But having relatively high expectations of the driving power of LED, and general LED driving power function singleness, poor expandability, inefficiency, useful life is short.
The utility model content
The purpose of this utility model is to provide a kind of and possesses wired and wireless communication capability, can networking, guarantee control and operation and the Fault Diagnosis of LED flexibility and reliability, and high efficiency, and can make the LED power supply that the whole system life-span lengthens greatly.
The technical solution that realizes the utility model purpose is:
A kind of LED power supply, comprise rectification circuit, power switch, the LC filter, LED load array, brightness regulator, main control chip, the constant current overvoltage detector, microcontroller, the wireless data access module, the cable data access module, wherein, microcontroller respectively with main control chip, brightness regulator, the constant current overvoltage detector, the wireless data access module, the cable data access module connects, the constant current overvoltage detector also with main control chip, brightness regulator is connected with Led load array, main control chip also is connected with power switch, rectification circuit, power switch, the LC filter, Led load array connects successively.
The utility model compared with prior art, its remarkable advantage:
(1) the utility model has adopted wireless and cable data access module, makes it possess wired and wireless communication capability, can networking, guarantee control and operation and the Fault Diagnosis of LED flexibility and reliability.
(2) the utility model makes LED be operated in constant current mode, and intelligent drives reaches more than 80% the operating efficiency of whole power supply, guarantees that led works long hours reliably, and the whole system life-span is lengthened greatly.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1:
A kind of LED power supply of the utility model, comprise rectification circuit, power switch, the LC filter, Led load array, brightness regulator, main control chip, the constant current overvoltage detector, microcontroller, the wireless data access module, the cable data access module, wherein, microcontroller respectively with main control chip, brightness regulator, the constant current overvoltage detector, the wireless data access module, the cable data access module connects, the constant current overvoltage detector also with main control chip, brightness regulator is connected with Led load array, main control chip also is connected with power switch, rectification circuit, power switch, the LC filter, Led load array connects successively; Wherein, rectification circuit comprises lightning-protection module, overcurrent protection module, anticreep module, rectification filtering module; Main control chip has added the delayed startup circuit.
Working method of the present utility model is as follows:
At first insert the ac220v civil power, by lightning-protection module, overcurrent protection module, anticreep module, to reduce Switching Power Supply to the pollution of electrical network.Enter rectification filtering module, alternating current is changed into high voltage direct current (dc310v).The Switching Power Supply main control chip starts the control power switch starts working, and in order to reduce rush of current, main control chip has added the delayed startup circuit.Power switch by transformer conduction, filtering input LED load array, is detected power by operating current and the operating voltage of constant current overvoltage detector to array, feed back to main control chip and microcontroller by constant current overvoltage detector (isolation optocoupler).Main control chip is with this signal with reference to comparing, and the opening time of control power switch is controlled the operating current of led array, possesses the PFC(active power factor correction in addition) control, the power factor that improves power supply reaches energy-conservation purpose.Simultaneously can be by the operating current of manual input circuit control led array, to reach its brightness of control.Also can by microcontroller control LED unlatching, close, brilliance control, and the monitoring of led array operating state (overheated, overvoltage, overcurrent), simultaneously the other parts circuit is monitored (such as the operating state of switch main control chip, the operating state of switching tube).Microcontroller also has wired and wireless ability to communicate.Wire communication comprises the PLC(power carrier communication that uses the existing power supply line) communication, advantage is to need not wiring, communication distance is far away; Another is special-purpose 485 communications or can bus mode, and advantage is that communication speed is fast, and data volume is big, and shortcoming is that the load capacity small distance is short, needs the cloth connection.Wireless telecommunications comprise wireless telecommunications and the wifi communication of 433M.This 4 class communication modes can networking, transfers data to console for centralized control, makes things convenient for point-to-point monitoring, control and the malfunction elimination of central station, the location.
