T8 Tube

 For security reasons, the voltage may be specified in the offline and isolation between the output   MR16  voltage . This application mode, the most cost-effective solution is to use flyback converter ( Figure 4 ) , in all isolated topologies, this approach required a minimum number of components . Transformer turns ratio can be used to output voltage buck, boost or buck-boost design very flexible, but the drawback is that the power transformer is basically a custom component . In addition, the FET and the input and output capacitors , there will be the case in high- stress components .

 A fixed light , you can use the "slow" feedback control loop to regulate the LED current in phase with the input voltage situations , for power factor correction (PFC). So you can adjust the desired average LED current , and can adjust the input current in phase with the input voltage of the situation , in order to provide high power factor .

LED dimming technology reduce the brightness by PWM Better

LED Flexi 

Often need LED dimming, for example, may sometimes need to adjust the display brightness or architectural lighting. There are two ways to achieve this goal, first, reduce the LED current, two are fast switching to the naked eye averages LED brightness. The least effective way is to reduce the current since the current between the light output is not entirely linear.
