确保电解电容器的长寿命,LED灯泡为例

　　Several years ago， I worked on a few designs for LED light bulbs. Very early on， it became clear that the temperatures of components in such light bulbs can get quite high. I personally measured component temperatures as high as +130°C in light bulbs purchased at local retail stores. Now admittedly， these were early LED bulb designs. Manufacturers now understand that， even though these LED bulbs consume substanTIally lower power than those they would replace， they sTIll must have good thermal engineering. This is the only way to get the lifeTIme of the electronics to match the lifeTIme of the LEDs themselves.
