The LED lamp with a single lamp power of 8W is equivalent to a 40W energy-saving lamp, and the appearance is very beautiful after being decorated with crystal. The high price, but let this beautiful and low-energy "love" stop at the people's family. Yesterday, Xi'an sent a good news: the investment of 680 million yuan, the annual output of 600,000 LED lamps, the high-power LED optoelectronic industry base project, is expected to break the price threshold, let LED into the Xi'an home lighting market.
High price prevents LED lights from entering the home in large areas
"The LED lights are so beautiful, and they are also very energy-efficient, that is, the price is too expensive." Into the lighting market in Xi'an, I often hear such consumption sounds before using LEDs as decorative decorative bright lights. . As the consumer said, the so-called LED lights that look like crystals are really beautiful. However, the reporter visited the building materials market of Beida Ming Palace, Hansenzhai building materials market and other places to understand that even a so-called LED lighting with LED as an auxiliary decoration, its price is as high as 3,000 yuan or even more than 10,000 yuan, so that many are optimistic Consumers of this luminaire are discouraged.
The reporter learned that LED is a new energy-saving light source. At present, more than 80% of the decoration designers have a certain understanding of LED, and have begun to use it in their own projects. However, in view of the high price point, LED can only do auxiliary decorative lighting in Xi'an. Even so, the price is several times higher than that of ordinary lamps, which is unacceptable to many families. This is a major problem that hinders LEDs from entering ordinary families.
680 million investment is expected to break the high price of LED lights
Can LEDs really enter the homes of Xi'an people? When many people who love LED lamps asked this question, the high-power LED optoelectronic industrial base project with an investment of 680 million yuan and an annual output of 600,000 LED lamps was settled in Xi'an. All of a sudden, the confused people saw the light brought by the "LED".
The reporter learned that Xi'an High-tech Zone yesterday signed a high-power LED optoelectronic industrial base project investment agreement with Dongguan Qinshang Optoelectronics Co., Ltd. and Xi'an Jiayu Energy Technology Co., Ltd., with a total investment of 680 million yuan. The capacity is 600,000 ç› LED lamps, with an annual output value of 2.5 billion yuan. The project is divided into two parts, the headquarters base and the manufacturing base. It is invested in three phases and strives to achieve production by March 2012, forming a production capacity of LED lamps with an annual output of more than 100,000 baht. After that, it will continue to expand the construction of the plant, expand the scale of production capacity, achieve the goal of producing 600,000 LED lamps per year, and strive to build the largest LED lighting products production and logistics distribution center in the central and western regions.
In this regard, the young economist Li Qing pointed out that some of the auxiliary LED lights sold in Xi'an are mostly from Guangdong and other places. In addition to the high cost of technology and materials, the cost of off-site transportation and its cost of loss prevention are also high. The key factor that is difficult to break. The high-power LED optoelectronic industrial base project is settled in Xi'an. The annual sales of 600,000 LED LED lamps are not only reduced, but also reduce the cost of transportation and loss prevention, and also reduce the technical cost due to the formation of Xi'an LED industry cluster. As a result, the high price of "LED" is just around the corner in Xi'an. In the future, it will no longer be rare for Xi’an people to buy LED lights.
What is 2.4g wireless module?
2.4g line module operating frequency in the range of 24400-2484mhz, can communicate through the scanning protocol, air rate up to 1Mbps, output power up to +4dBm, the module has the advantages of low power consumption, cost-effective. Movingcomm's current 2.4g antenna modules are: IOT04, IOT05, IOT09, IOT18, IOT60, etc. Users can choose a variety of modules with a transmission distance of 50-500 meters according to cost considerations.
Second, the role of 2.4g wireless module
Function 1, for the formation of a star topology wireless communication network, and must be a multi-point star topology, some extraordinary places need wireless communication. On the one hand, the transmitting and receiving module is cheap, and the cost of forming the star topology is relatively low. On the other hand, the transmitting and receiving module can adopt the modular design, which is small in size, easy to use and easy to integrate. For the wireless network with low communication speed and close distance, the transmitting and receiving module is very practical.
Function 2, for wireless multi-channel (parallel) control. Such as complex remote-controlled robots, some places require multi-channel (parallel) control. One method is to use the receiving module to directly connect to the decoder, and then connect to the relays and other electronic components to drive the subsequent controlled object; the other method is to use the receiving module to connect to the single chip microcomputer, and after the data is disposed of, the single chip microcomputer is connected to the relays and other electronic components to drive the subsequent controlled object. Usually a pair of transmitting and receiving modules can achieve up to six parallel wireless control, if the required number of channels is greater than six, you can use multiple pairs of transmitting and receiving modules, and work at the same time to meet the actual needs.
Function 3, used for general serial port, RS232 antenna data transmission, there are usually many control instruments and equipment using serial port, and communication with these devices must meet the requirements of serial port. In some extraordinary places, when the industrial control site must use the antenna transmission mode, it is natural to choose the transmitting and receiving modules mentioned in this article, but it must be explained here that to use this communication mode, the corresponding software must be prepared at the transmitting end and the receiving end respectively to achieve the conversion of file formats, in order to achieve the purpose of wireless communication, if the communication system is full-duplex. It can be achieved by using two pairs of transmitting and receiving modules, working simultaneously.
Third, 2.4g wireless module application field
2.4G wireless module is widely used in wireless health sports products, wireless mouse and keyboard, product information push, wireless remote sensing, wireless ranging system, alarm security system, smart home, toy control, tire pressure monitoring and other fields. With the 2.4G wireless module, all the whole house wireless smart home can be linked together, you can control all the smart home devices through the link of the network, and then you can control the switch of all the whole house wireless home, adjust the brightness of the lamp, adjust the rise and fall of the curtain, etc., through the continuous innovation of technology, The whole house wireless smart home can be controlled by a small white robot voice, can be controlled by a smart scene panel, can be controlled by sensors and so on.
Four, 2.4g wireless module how to choose antenna
In general, the 2.4g wireless module requires an impedance of 50 ohms, a red wire used with 2.4g, a 2.4g folded rod antenna, a 2.4g gold-plated straight head rod antenna, a 2.4g gold-plated elbow rod antenna, and a 2.4g small suction cup antenna. These antennas are special antennas designed for 2.4g wireless communication system, antenna standing wave ratio performance is good, small size, clever structure, easy installation, stable performance, with good anti-vibration and aging ability.
