As technology matures and prices continue to fall, LED (Light Emitting Diode) bulbs, a new generation of environmentally friendly lighting bulbs with long service life and low power consumption, are in short supply in the Japanese market, and they also attract Japanese well-known motor manufacturers to enter this market. The field has led to an increasingly fierce competition in this market. It is reported that LED bulbs have been available in Japan about 10 years ago, but the technology was not very mature at the time, the bulbs were not bright enough and could only be used for emergency indications. Since then, due to technological advances, Japanese manufacturers have developed LED bulbs that can replace incandescent lamps. Since then, LED bulbs have gradually gained consumer recognition, and the process of commercialization has also accelerated. At present, the life of LED bulbs in the Japanese market is about 40,000 hours, which is equivalent to 40 times that of incandescent lamps and 6 times that of bulb-type fluorescent lamps. The power consumption is only about one-eighth of incandescent lamps, and bulb-type fluorescent lamps. Less than two-thirds, the energy-saving effect is very obvious. In addition, the price of LED bulbs has dropped to half of the original price, and the unit price is only about 4,000 yen (about US$88). LED bulbs with increased brightness and lower prices soon became popular among Japanese consumers, and this year they experienced the first peak sales season. After the price of LED bulbs has been reduced, many large-scale electrical stores have experienced out-of-stock phenomenon. LED bulb manufacturers are also complaining because of too many orders and production can not keep up. The popularity of LED bulbs not only encourages manufacturers to increase production development, but also attracts many motor manufacturers to enter this field. Toshiba Corporation was one of the first manufacturers to develop LED bulbs. In 2007, it was the first to launch its products in the market. In September this year, the company announced that it will further strengthen its LED bulb business and plans to invest 100 billion yen in equipment investment. In 2015, we increased our sales from the current 20 billion yen to 350 billion yen, and increased the sales share in overseas markets to over 30%. The company also introduced LED bulbs that can adjust brightness and new products with the highest brightness in the industry. Japan's Matsushita Electric Co., Ltd. also decided to enter the home LED lighting market in September this year, and plans to launch 10 "EVERLEDS" series of LED bulbs in late October. The company said that the series of LED bulbs use Panasonic's self-developed exothermic technology, which has high energy-saving performance. According to the way of general household use, the annual electricity bill is only 300 yen, 2,000 yen less than incandescent lamps, and the retail price is between 4000-5000 yen. The company will also introduce a unique small LED bulb. In addition, large motor companies such as Sharp, Mitsubishi Electric and NEC have also entered the LED bulb market, and it is expected that the competition in this market will become more intense in the future. Environmental protection and energy conservation has become a major topic in today's world. Countries are striving to promote environmentally-friendly and energy-saving products. Many countries have plans to phase out the production of incandescent lamps. The reason why major motor manufacturers in Japan do not hesitate to participate in and strengthen the LED bulb business is to see the broad prospects of this new lighting equipment market.
