Use:
 the led lighting appliances with the power supply (AC power supply), and other long-life power circuit so far, although the Emperor LED the long service life, but the system of life is by the power supply components with the life of electrolytic capacitor.    
Therefore, the life of this power is going to last.  
• The world's first, do not use Electrolytic Capacitor power components.    
Features * smoothing circuit does not use electrolytic capacitors.   
1, because the circuit does not use electrolytic capacitors, so there would be no obstacles life part. So life is unknown.   
　(Reference: General market replacement bulb of led lights is incandescent life of about 40 times the equivalent of 4 million hours. ) And because the LED is DC current drive parts, when AC power is switched on, typically use rectifier parts and smoothing circuit of DC power supply, the smooth stabilization loop of necessary Electrolytic Capacitor will vary depending on the temperature and own fever rising 10 ° c, causing life by half, so Electrolytic Capacitor hindered the led lighting appliances for life.     
2 and power: If you use a 4 million hours, and bulb can save approximately 27,900 million yen, reduce CO2 emissions of about 495kg.  
　(Reference: 4 million hours to 12 hours a day to light, you can use about 10 years) 3, the master is in the United States, South Korea, Taiwan, Japan has obtained a patent for a patent.
