Abstract
The invention discloses a driving system of an LED energy-saving lamp. The driving system comprises a control module, a driving module, an input module and an alternating-current noise immunity module. The input module is connected with the alternating-current noise immunity module, the control module and the driving module sequentially. The driving module includes a plurality of LED driving modules with different colors. An output protection unit is connected to the LED driving modules with the different colors in parallel. A direct-current conversion module is connected to the alternating-current noise immunity module. The driving system has the advantages that constant current driving of the LED energy-saving lamp is achieved by the driving system, so that influence on the reliability of the lamp due to the fact that a driving current exceeds a maximum rating is avoided, expected brightness requirements are met, and brightness and chrominance uniformity of LEDs is guaranteed; the driving system is simple in structure, reasonable in design, convenient to mount and use and high in applicability.
Description
Technical field
The present invention relates to a kind of LED drive system, particularly a kind of LED electricity-saving lamp drive system.
Background technology
LED electricity-saving lamp is the lighting source of new generation after compact fluorescent lamp (i.e. common energy-saving lamp).Compare common energy-saving lamp, the environmental protection of LED electricity-saving lamp is not mercurous, recyclable recycling, and power is little, specular removal, and the long-life, namely open namely bright, resistance to frequent switch, light decay is little, rich color, tunable optical, and change is abundant.A large amount of use common energy-saving lamp, can cause mercury pollution, contaminated soil water source, thus indirectly contaminated food products, environmental hazard can not be despised.Due to the semiconductor device that LED is characteristic sensitivity, again there is negative temperature characteristic, thus need to carry out steady-working state and protection to it in application process, thus create the concept of driving.LED component is to the requirement of driving power near harshness, and LED, unlike common incandescent lamp bulb, directly can connect the electric main of 220V.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides one can stabilized driving, ensures the conforming LED electricity-saving lamp drive system of each LED luminance, colourity.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of LED electricity-saving lamp drive system; comprise control module, driver module, input module and exchange immunity module; described input module connects interchange immunity module, control module and driver module successively; described driver module is divided into the LED drive module of some different colours; in the LED drive module of described some different colours, an output protection unit in parallel, described interchange immunity module also connects DC converting module.
As a further improvement on the present invention, described input module is civil power input module.
As a further improvement on the present invention, described driver module comprises red-light LED driver module, blue-ray LED driver module, green light LED driver module and white LED driver module.
The invention has the beneficial effects as follows: LED electricity-saving lamp drive system of the present invention carries out constant current driving to LED electricity-saving lamp, drive current is avoided to exceed maximum rating, affect its reliability, obtain the brightness requirement of expection, and ensureing the consistency of each LED luminance, colourity, structure of the present invention is simple, reasonable in design, easy to install, applicability is wide.
