Abstract
An LED (Light Emitting Diode) fluorescent lamp system which is self-adaptive to various kinds of fluorescent lamp ballasts comprises a microcontroller, a voltage-stabilizing circuit, a power supply interface, a constant-current circuit and an LED lighting system, and is characterized in that: the microcontroller identifies and controls normal workings of the whole LED fluorescent lamp by acquiring circuit signals of the traditional fluorescent lamp ballast. The self-adaptive LED fluorescent lamp of the utility model has the advantages of simple installation, strong adaptability, stable performance, and no flicker; and the self-adaptive LED fluorescent lamp is suitable for various kinds of the fluorescent lamp ballasts.
Description
Technical field
The utility model relates to the control of LED fluorescent lamp, is specifically related to a kind of system that can adapt to the traditional fluorescent lamp ballast automatically and control the LED fluorescent lamp.
Background technology
The LED fluorescent lamp is compared with traditional fluorescent lamp as a kind of energy-efficient durable electric light source, has advantages such as power consumption is low, the life-span long, pollution-free, has begun to replace gradually traditional fluorescent lamp at present.
The principle of luminosity of traditional fluorescent lamp is different with the LED fluorescent lamp.Traditional fluorescent lamp needs a ballast to start luminous; And the LED fluorescent lamp only needs the constant-current supply of an AC-DC; Because traditional fluorescent lamp has been used decades; Each country, manufacturer have developed the ballast that various principles, specification; Therefore substitute in the traditional fluorescent lamp process at the LED fluorescent lamp, solve LED fluorescent lamp constant-current supply and the compatible problem of various ballast with regard to needs.
At present practical LED daylight lamp power source with the ballast compatibility on have a lot of problems; Ability operate as normal on a certain ballast; But on other ballast, just might cause the flicker of LED fluorescent lamp, deepening even burn; Needing has so just greatly increased the cost of LED fluorescent lamp replacement traditional fluorescent lamp to the different different LED daylight lamp power source of ballast exploitation, has a strong impact on promoting the use of of this novel light-emitting device of LED fluorescent lamp.
The utility model content
The technical problem that the utility model solved is to provide a kind of various ballasts is had the intelligent LED fluorescent lamp system of adaptation function, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of LED fluorescent lamp system with adaptation function; Comprise microcontroller, voltage stabilizing circuit, power interface, constant-current circuit, LED luminescent system; Its principle is through integrated microcontroller on LED fluorescent lamp wiring board, to gather and be connected the fluorescent lamp ballast circuit signal on the power interface; With the various fluorescent lamp ballast signals that prestore in itself and the microcontroller relatively after; To constant-current circuit output control signal corresponding, after constant-current circuit converts the direct current constant current into, supply connected LED particle to make it normally luminous.
Adopted technique scheme, the utility model is simple in structure, and simple installation all can operate as normal under multiple fluorescent lamp ballast.
Description of drawings
