Recently, 12,000 LED bulbs produced by Putian Zhongke Wanbang Co., Ltd. were exported to the Netherlands. This is the first time that Fujian Port has exported LED high-efficiency environmental protection and energy-saving lamps. In addition, it is also exported to Japan, Greece, Malaysia and other countries. Around the dollar.
LDE, a light-emitting diode, is a solid-state semiconductor device that converts electrical energy into visible light, which converts electricity directly into light. A 4 watt LED bulb is more than 90% more energy efficient than a conventional incandescent lamp, and more than 70% more energy efficient than an ordinary energy saving lamp.
It is understood that the current city area has squeezed nearly 100 million yuan of funds, built a 1km long Mulanxi Yulin Bridge, and opened up a new area with a planned area of ​​more than 8,000 acres, and specially invited experts from the Development Research Center of the State Council to demonstrate and prepare. Focus on cultivating LED leading industries, and prepare to cultivate Hualin Park into a LED industry base with Chinese characteristics in 3-5 years, and achieve the goal of exceeding 10 billion yuan in output value.
As far as the market is concerned, China's accession to the WTO and Beijing's successful bid for the Olympic Games have become a new opportunity for the development of the LED display industry. The domestic LED display market has continued to grow. Currently, in the domestic market, the domestic LED display market share is nearly 95%. The international market for LED displays is expected to grow at a rate of 30% per year. However, the major manufacturers of LED displays are concentrated in Japan, North America and other places, and the share of China's LED manufacturers' exports is negligible. The export of LED bulbs produced by Putian Zhongke Wanbang Co., Ltd. in the Netherlands is also a big step for China's LED industry to the world, indicating that the development level of China's LED industry is gradually aligning with the world.
- The Description of GPS Antenna
- GPS is a terminal for positioning or navigation by receiving satellite signals. An antenna is needed to receive the signal. GPS satellite signals are divided into L1 and L2 with frequencies of 1575.42MHz and 1228MHz respectively. L1 is an open civil signal and the signal is circularly polarized. The signal strength is about -166dBW, which is a relatively weak signal. These characteristics decide to prepare special antennas for the reception of GPS signals
- The use of GPS in cars will become more and more common. But the automobile shell, especially the automobile explosion-proof film produces the serious obstacle to the GPS signal. An external antenna with a magnet that attaches to the roof of the car is necessary for a GPS in the car.
