According to report, this year, as one of the main raw materials for the production of energy-saving lamps - three-color phosphors, the price rose from 300 yuan / kg to 3,000 yuan / kg in just a few months. There are industry insiders frankly: cost pressures make it difficult to promote difficult energy-saving lamp products due to price reasons, and then hit.
The price does not adjust enterprises difficult to make money Yesterday, the reporter visited Shijie lighting a street part of the dealer, a lighting shop owner told reporters that the most recent period, frequently received energy-saving lamp manufacturers price notification, sometimes fine-tuning, there are The adjustment will be larger. The person in charge said that as a terminal retailer, due to direct confrontation with consumers, the product price adjustment frequency can not be too high, otherwise it is easy to run away some of the regular customers.
According to report, almost all lighting dealers in the energy-saving lamps, this year have made several adjustments to the terminal sales price, because almost all brands of energy-saving lamp manufacturers, this year made a significant increase in energy-saving lamp factory prices Adjustments.
According to industry sources, the price increase of energy-saving lamps is inevitable. Big brand product gains may be controlled at 10%-20%. The reason why the current increase is uncertain is because the price of rare earth raw materials has been rising. All manufacturers hope to determine the specific price increase after the raw material price is slightly stable. Affected by the factory price adjustment, the current general fluorescent tubes on the market have already made price adjustments, and the price of each ordinary fluorescent lamp has increased by 1-2 yuan.
In the interview with the reporter, Wang Manqiu, general manager of Haohao Lighting, said in an interview with reporters that the price increase is indeed a frustrating move. If the production enterprises do not increase prices, it is estimated that few companies can withstand the increase in raw material prices. If you increase prices, you will lose money."
According to Wang Manqiu, the market price of tricolor phosphors, one of the most important raw materials for energy-saving lamps, has exceeded 3,000 yuan/kg, and the price of this rare earth product at the beginning of the year was only 300 yuan/kg. "The most ridiculous thing is that some time ago, three-color phosphors have doubled in price in a matter of days. What do you think companies do not raise prices?"
The person in charge of Oaks Lighting also told reporters that since the beginning of this year, affected by the skyrocketing price of three-phosphor phosphors, their company's energy-saving lamps have made major adjustments, whether export or domestic sales. “The price of three-color phosphors has been relatively stable in the recent period, and the first round of price adjustments by energy-saving lamp manufacturers has basically come to an end. If the price of three-color phosphors goes up again, it does not rule out the second round of price adjustments by production companies.â€
The rapid increase in the cost of rare earth products for enterprises to relocate the price of energy-saving lamps for the promotion of this product is undoubtedly worse. In Shiyi Lighting, a street-sales shop, a 5-watt ordinary energy-saving lamp is priced at 5 yuan (subsidy), but the same brightness of the market's incandescent bulbs only need 1.5 yuan or 2 yuan, a significant drop in product prices.
As raw material prices have soared and labor costs have risen faster, many companies have had to increase the market price of their products in order to make up for corporate profits. In addition, energy-saving products in the research and development and promotion of the huge early costs, these have led to energy-saving lamps, especially high-quality energy-saving lamps product terminal prices are high, its price does not have too strong competitiveness.
“Although energy-saving lamps are energy-efficient, the prices are relatively much higher, which is why the state is making great efforts to promote energy-saving lamps in the form of subsidies. If the price of energy-saving lamps rises due to rising raw material prices, energy-saving lamp promotion will be even more effective. Difficult.†Wang Manqiu said in an interview with reporters.
As the largest energy-saving lamp production base in Guangdong Province, Zhongshan District has exported goods worth as much as US$215 million in 2010. However, due to the guidance of national policies, a large number of companies wishing to receive state subsidies have invested in LED lighting, compared with CFLs. The investment in energy-saving lamps seems to be insufficient.
Although the theoretical energy saving effect of energy-saving lamps is slightly lower than that of LED lighting, the maturity of the production process, prior investment, lighting effects, and prices are far superior to LED lighting. From the perspective of domestic and international market demand and energy-saving emission reduction requirements, Energy-saving lamps are still the best choice for replacing high-energy lighting products such as incandescent lamps and halogen lamps at this stage. However, in the promotion process, the energy-saving lamps are somewhat embarrassing. According to the reporter’s understanding, the energy-saving lamps produced in Zhongshan are mainly exported to the backward regions such as the Middle East, South America, Southeast Asia, and Africa. In addition, the long-term low-price competition, the use of inferior halogen powder lamps, and high-power competition have caused vicious competition. It is not energy-saving, and even conceptually mistaken for high-energy fluorescent lamps.
According to industry sources, from April onwards, with the enactment of the National Standard for Rare Earth Tricolors, the supply of rare earth resources has been insufficient, resulting in prices of three-phosphor powders that have doubled several times, combined with rising prices of other raw materials caused by domestic inflation. A serious impact on the development of the energy-saving lighting industry in Zhongshan has forced some small and medium-sized enterprises to choose to wait and see or not accept orders in order to avoid trade risks and the industry is facing a reshuffle. In order to reduce the use of land resources, labor pressure and increasingly stringent regulatory requirements, some companies will move their production plants to Jiangmen, Yangjiang and Jiangxi provinces.
Domestic communication, 4 g module in addition to support two kinds of LTE FDD LTE/TD - LTE standard, also compatible with 2 g / 3 g down, support td-scdma/WCDMA/EDGE/GP/GSM/CDMA1X/EVDO mode. The data service downstream rate can reach up to 100Mbps, the uplink rate can reach up to 50Mbps, providing customers with high-speed Internet access and wireless data connection and other functions. In addition to providing high-speed data access, it also provides voice, SMS, communication book and other functions, which can be widely used in notebook, tablet, touch screen communication devices, smart phones, video surveillance, multimedia mobile phones and vehicle equipment and other terminal products and vertical applications. Today, I will introduce you to what is 4G module and how to use 4G module.
What is 4G module
4G module said TD-LTE and FDD-LTE and other LTE network standards are collectively referred to. It has the characteristics of fast communication speed, wide network spectrum and flexible communication. 4G module refers to a product whose hardware is loaded to the specified frequency band, software supports the standard LTE protocol, and software and hardware are highly integrated and modular. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Second, how to use 4G module
The 4G module is usually inserted into the circuit board or the patch module is welded to the circuit board, and the corresponding SIM card is inserted, and the network is connected through the 4G cellular network. In the common transparent transmission mode, data can be directly sent to the target server through the 4G module, and the 4G module can receive data from the server at the same time, and send the data to the serial port, which is received by the serial port device connected to the 4G module. Users do not need to pay special attention to the data conversion process between serial port data and network data packets, only need to insert the module to the target position, simple connection and parameter setting, you can achieve transparent transmission between the serial port and the network end.
