| 总结: | Nowadays, LED or light-emitting diode is the most efficient way in illumination and lighting system due to the advantages of extremely energy efficiency and operating time compared to conventional lighting. LED’s have an outstanding operational life time expectation of up to 10 years of continuous operation or double for an average of 8 hours per day. However, the existence of electrolytic capacitor as storage and smoothing capacitor in the LED driver make it bulky and reduces its lifespan. This is because the characteristic of electrolytic capacitor is acidic wet that can be dried when excessive heating is applied. |
