Japan's earthquake has affected the aftermath of the wave, and it has extinguished more than 20,000 street lamps for power saving.

The power shortage caused by the "3.11" earthquake in Japan is still continuing. In order to save electricity, Japan has extinguished some of the street lights of the national highways. According to the survey, as of August 1, a total of 21,670 lamps were extinguished, accounting for 7.5% of all national roads along the national route.

However, many people are worried that there are no street lights. The dim place is very dangerous and it is easy to cause traffic accidents. Some places have already restored the street lighting.

Plastic Package Diode.Among the electronic components, a device having two electrodes allows only the current to flow in a single direction, and many uses apply its rectification function. The Varicap Diode is used as an electronic adjustable capacitor. Most of the diodes have a current directionality that we often call the "Rectifying" function. The most common function of a diode is to allow only current to pass in a single direction (referred to as forward bias) and block in the reverse direction (referred to as reverse bias). Therefore, the diode can be thought of as an electronic version of the check valve.
