must be LED Downlights

In lighting applications over a wide input line voltage, output voltage, and temperature variations and accurate LED current regulation is crucial, because the LED brightness change must be  LED Downlights imperceptible to the human eye . Similarly, to ensure that the LED has the longest working life , do not use more than its maximum rated current to drive the LED is very important. In the isolated flyback applications , LED current regulation is not always direct, it is often necessary to close an optocoupler feedback loop required , or may increase an additional conversion stage .

 However, both methods have brought the complexity and reliability issues. Fortunately, some LED driver IC is designed using a new design method , without these additional components or design without increasing the complexity of the case , can accurately regulate the LED current.

Finally, from incandescent to LED lights change rapidly , the biggest obstacle is the LED-based solution cost and size. Consumers are accustomed to spend less than $ 1.00 for a 60W incandescent lamp, spend abo  LED Flexi Strip ut $ 3.00 for a CFL lamp . To spend more than $ 30 for an LED lamp , the consumer is a big obstacle. Taking into account the lifetime of the LED replacement power costs and lower costs at this price for a LED light does have economic significance, but consumers are not accustomed to this link to see the problem .
