With the improvement of people's environmental awareness, as well as the improvement of LED performance and the reduction of cost, the realization of LED-based lighting era is no longer a piece of paper. In 2009, the LED lighting market was significantly more prosperous.
In the face of the upcoming universalization period, while the old lighting manufacturers try their best to seize the LED lighting market share, many other industry manufacturers have also stepped into the LED lighting market, hoping to seize this business opportunity. These newly added latecomers have launched a strong offensive against the established players in the lighting market, and their strength cannot be ignored. For example, after the introduction of low-priced products by Sharp, the price of LED bulbs has fallen all the way. Faced with this situation, veteran manufacturers use their rich product lines as weapons to face emerging forces.
New and old manufacturers are united, and their offense and defense are fierce. LED lighting has already ushered in the Warring States era.
Low-priced products spurred market competition and gradually became hot
Following the launch of the first 4.3W LED bulb in March 2009, Toshiba Lighting Technologies introduced a new LED bulb in July this year, which is half the price of the previous product. Under the competitive pressure of Sharp's low-priced products, Toshiba has no choice.
Amazing price
In December 2007, Toshiba Lighting Technology Co., Ltd. introduced a small reflective bulb type LED lighting product with E26 lamp head and brightness equivalent to 40W incandescent lamp. In August 2008, the company introduced LED lighting products with brightness equivalent to 60W incandescent lamps. However, in order to meet the requirements of the power supply circuit and the surface area of ​​the heat radiation, the size of the two products is relatively large, and the application range is also limited.
In March 2009, Toshiba Lighting Technology released a 4.3W LED bulb with a brightness equivalent to 40W incandescent lamps. The manufacturer's suggested retail price (MSRP) is 10,500 yen (100 yen is about 7.63 yuan), and the market price is about It is 8,000 yen. The shape and brightness of this LED bulb is no different from that of an ordinary incandescent bulb. Its launch marks a revolutionary advancement in LED bulbs, and previous problems of insufficient brightness and limited application have been resolved.
In 2008, Sharp entered the LED lighting market with a low-cost strategy. In June 2009, the company released a brand-new LED bulb with a market price of about 4,000 yen, which is only half of the competitive products. There was a strong shock wave in the market. Sharp's low-priced products forced Toshiba Lighting Technology to launch LED bulbs with a brightness equivalent to 60W incandescent lamps in July 2009. The manufacturer's suggested retail price is about 5,000 yen, and the market price is about 4,000 yen. Compared with similar products launched by Toshiba four months ago, the price has dropped by 50% (see Figure 1 and Table 1).
In the LED lighting market, other Japanese companies are also close behind. In July 2009, Ecorica significantly lowered the price of LED bulbs launched by the company in April of the same year, down from the original 7,200 yen to 3,780 yen; IRISOHYAMA also launched a product with a price of 3,980 yen. NEC Lighting released an L ED bulb in August 2009, and the press release stated that its price has strong market competitiveness. In late October, Panasonic also launched 10 EVERLEDS series LED bulbs at the same price as competing products.

Sharp's goal of adopting a low-cost strategy is to hope to establish a foothold in the LED lighting market as soon as possible. The company explained: "Sharp is a latecomer to the LED lighting market, so we have chosen such a strategic price." Obviously, Sharp is the top priority for market share rather than profit.
Lighting market will expand 4 times in the next 4 years
At present, there are disputes among the Japanese LED lighting market, including veteran manufacturers, emerging powers and overseas companies. They are full of confidence in the future of the LED lighting market. According to a report by Fuji Keizai, a Japanese market regulator, the LED lighting market in Japan will expand at least four times between 2008 and 2012: although the overall growth rate of the Japanese lighting market was only 8.6% during the same period, the market for LED lighting The scale will increase from 13.3 billion yen to 57.8 billion yen, and will account for 12% of the overall lighting market by 2010 (see Figure 2). Since 2006, the global white LED lighting market has grown at an annual rate of about 50%. In 2009, the market has reached 160 billion yen. In the next few years, the market will accelerate growth, and the market size in 2012 is expected to increase to three times that of 2009 (see Figure 3). At the same time, the application of white LEDs in the field of lighting will also be greatly expanded, and will account for more than 20% of the entire white LED market by 2012.

The elimination of incandescent lamps has become a global trend and promotes the development of the LED lighting market. The Ministry of Economy, Trade and Industry and the Ministry of the Environment have asked for the production and sales of incandescent lamps to be stopped by 2012. Lighting manufacturers are cooperating and have announced the date of suspension. Fluorescent lamps are currently the most common alternative to incandescent lamps, but LEDs are increasingly favored by people for their long life and good color temperature characteristics.
Big companies have seized the market
Due to the high expectations of users and the rapid growth of the market, since 2008, the old companies in the lighting market have launched new LED lighting products. At the same time, many large companies that have made great achievements in other industries have begun to enter the city. In September 2008, Sharp launched low-cost basic lighting and spotlighting LED products, becoming the first companies to enter the market. At the end of 2008, electronic component manufacturer ROHM Semiconductor Corporation launched LED spotlights; in the spring of 2009, the company jointly developed a storefront basic lighting product with a design company. Daiwa Housing Industry Co., Ltd., together with companies such as Kyocera and NABESHO, has developed LED basic lighting fixtures for commercial facilities.
In addition, leading lighting manufacturers such as Philips Lighting and OSRAM are also expected to expand their market share by developing new LED lighting products. Philips Lighting not only introduced general-purpose LED lighting, but also LED spotlights, indirect lighting and other special lighting fixtures.
Catching up with fluorescent lighting
Why are so many companies in other industries entering the LED lighting market? Why is the LED lighting market so active? The main reason is that with the continuous improvement of LED luminous efficiency and the continuous decline of prices, coupled with other breakthroughs in LED lighting, LED lighting has begun to outstrip fluorescent lighting in some aspects. Panasonic, the director of the LED component development center of the Matsushita Electric Lighting Business Division, said that LED will successfully surpass fluorescent lighting around 2012.
First, the analysis of the LED package shows that the luminous efficiency of the LED is steadily increasing. According to the blueprint for technology development announced by the Japan LED Association (JLEDS) in 2008, the luminous efficiency of high-efficiency LED fluorescent tubes will reach 120lm/W in 2009, and the luminous efficiency will exceed 150lm/W in 2015. Some people in the industry believe that this goal can be achieved 1 to 2 years in advance. Yamada Fan Xiu, vice president of Philips Lumileds Lighting Japan, said: "In the next two to three years, we will introduce LED products with luminous efficiency up to 150lm/W." Nichia Chemical Industry Co., Ltd., Vice President and Chief Operating Officer Tian Qideng also said: "We have achieved a luminous efficiency of 120 lm / W ~ 130 lm / W, and the product with luminous efficiency of up to 150 lm / W has also been mass-produced." 
advantage:
a. Compared with the traditional Office Projector, the internal structure of the home 3D projector is simpler and the volume is much smaller, which is convenient to move and carry.
b. It can bring a better viewing effect to the user, and its large screen can bring a certain visual impact to the user.
c. Compared with traditional projectors, home 3D projectors have more advantages in the color of the picture, which can reach 120% of the NTSC color gamut, and the colors are rich and diverse.
