Description

Luminosity is regulated fluorescent lamp

Technical field

The utility model relates to a kind of fluorescent lamp, the particularly a kind of fluorescent lamp that can regulate light and shade luminosity.

Background technology

General fluorescent lighting circuit is to be formed by combining by power supply, mains switch, ballast, fluorescent tube, starter.The brightness of fluorescent lamp is to be decided by the electric current by fluorescent lamp, the ballast that uses belongs to the inductance type capacitor more now, when the supply voltage that uses and frequency are when fixing, the electric current that flows through fluorescent lamp is that the induction reactance by ballast has determined, but the induction reactance of present ballast is changeless, so the luminosity of now general fluorescent tube can't be regulated.

General conventional fluorescent lamps with city's electric boost, is used the starter fluorescent lamp that starts light with ballast.On when work ballast, there is the electric energy of part to be converted into heat and slatterned; Aspect in addition, on function, now the ballast of Shi Yonging belongs to the inductance type capacitor more, when the supply voltage that uses and frequency are when fixing, the electric current that flows through fluorescent lamp is that the induction reactance by ballast has determined, but the induction reactance of ballast is changeless, so the luminosity of general fluorescent tube can't be regulated, more can not issue out any information in the situation that people leave illumination zone and regulate luminosity automatically, perhaps turn off the light automatically, waste electric energy.

Summary of the invention

The purpose of this utility model provides a kind of luminosity that can effectively overcome the problems referred to above generation and regulates fluorescent lamp, and it in use can regulate the light and shade of fluorescent lamp, and need not operation, energy efficient to greatest extent.

The purpose of the utility model structure is achieved in that it includes fluorescent tube, electric ballast, lamp socket, wherein fluorescent tube is installed on the lamp socket, electric ballast places lamp socket, electric ballast inside includes filter rectifier, half-bridge drive circuit, electric ballast connects fluorescent tube, its improvement is: adding on filter rectifier and half-bridge drive circuit has the luminosity regulating circuit, the luminosity regulating circuit includes Switching Power Supply, with door switch, Switching Power Supply be connected with door switch, Switching Power Supply connection processing device, with door switch linking number analog conversion circuit, D/A converting circuit is connected on the processor, processor is connected with data-interface, data-interface connects signal of telecommunication loader, and wherein, Switching Power Supply connects filter rectifier, be connected half-bridge drive circuit with door switch, signal of telecommunication loader links to each other with external control devices:

In the said structure, lamp socket is the cylinder of T8 fluorescent tube specification, and fluorescent tube is the T5 specification.

In sum, filter rectifier of the present utility model, half-bridge drive circuit, Switching Power Supply, with door switch, processor, D/A converting circuit and data-interface have been formed a numeral can decide address illumination control electric ballast, when work, processor distributes an address for each fluorescent lamp in a fluorescent lamp or the one group of fluorescent lamp, the external equipment that data-interface connects can be controlled adjusting brightness of fluorescent lamp, be loaded into adjusting information and address information in the alternating current of power line by the signal loader, data-interface returns to processor after receiving, processor sends regulates operation information, convert through D/A converting circuit that analog signal sends to and door switch to, implement to regulate operation with door switch control half-bridge drive circuit, it allows the fluorescent lamp of diverse location, can utilize multi-form grid line to transmit data, as twisted-pair feeder, power line, infrared ray, methods such as electromagnetic wave transmit data, make numeral in the fluorescent lamp of variant position can decide address illumination control electric ballast and can carry out control switch, light regulating technology, thus the power-saving control that reaches a cover simple intelligentization is thrown light on.In addition, this product can simple and easyly be changed existing T8 conventional fluorescent lamps directly, fast, is consistent with T8 on luminosity.
