|Abstract: ||Nowadays, the LED system is a wide variety of application for general lighting,decorative
lighting,LCD display backlighting,and so on. Moreover, LED technology have improve a lot
which can handle the high driving current and high thermal capability (e.g. 3W, 700mA).
There are many advantages for LED system which have longer life time , high brightness , no
toxic materials and low profile package.
However, if LED use with higher junction temperaure ,the LED light output will be derating.
It will shorten the LED lifetime .
In this project , I need to design a LED light bulb to replace the traditional light
bulb(60/100W). Therefore , it aims to design a heatsink in order to maximize the LED light
And then, I also need to develop a Triac dimmable LED driver for dimming the LED light
