Replace a 100W incandescent lamp with a 20W energy-saving lamp, which can save energy value of more than 200 yuan per year by 8 hours per day.
With the gradual improvement of energy conservation awareness, energy conservation has become an important selling point for merchants to promote energy-saving lamps. However, many consumers complain that the price is too expensive, the quality of the product is mixed, I don't know how to choose... The "blind spot" in the consumer field has made the energy-saving lamp lose its proper aura.
The difference in price difference makes people unable to understand
In a commercial plaza, the reporter found that energy-saving lamps are mostly foreign products, and the price is roughly between 15 and 30 yuan. The price of ordinary incandescent lamps is priced at 1 to 2 yuan, which is in stark contrast to the "high price" of energy-saving lamps.
"The goods are not worth the loss." The reporter immediately went to a lighting city near the train station. All the way, the price tag is less, the operators mostly bid for 7 to 10 yuan. Mr. Li, who is buying energy-saving lamps in Nanhu Lighting City, told reporters that it is really unforgettable to compare the price of energy-saving lamps in supermarkets with the prices in large professional markets. “There are a lot of brands to be dazzled, in the end who is good value for money, can’t figure it out.â€
According to industry analysts, the main source of the current gap in energy-saving lamps is that many large-scale commercial supermarkets have set fees for energy-saving lamps, which has raised the pricing; normal price.
Poor quality leads to "consumption barriers"
The price makes the consumer unable to see the bottom, and the quality is covered with a thick layer of "veil". Mr. Liu, who lives in the Donghu community, recently renovated the home, and all the households used 7 yuan of energy-saving lamps. A friend in the industry told him that "a few dollars of energy-saving lamps are basically fake and shoddy products", Mr. Liu was half-hearted.
According to He Yingbin, general manager of Changsha Guiya Lighting Installation Project, the production of a qualified energy-saving lamp, the market price of at least 10 yuan, the production and sales links are likely to make a profit. At present, some small enterprises use halogen powder instead of high-cost three-primary phosphors to produce energy-saving lamps that do not meet national standards. These products quickly occupy the small majority of consumers in small domestic retail markets at very low prices. Know which are formal and which are fake.
The high price, coupled with the quality can not meet the requirements, the energy-saving effect of energy-saving lamps will inevitably be discounted, which is undoubtedly "increasingly worse" for consumers' consumer confidence. “Energy-saving lamps are not energy-saving†and “energy-saving lamps save electricity and save money†have become a common psychology among consumers. There is a strange phenomenon in the data: 90% of the world's energy-saving lamps are produced in China, while the proportion of energy-saving lamps in China is less than 20%.
Energy-saving account full of consumer confidence
In fact, energy-saving lamps have great potential for energy conservation. Hunan Yuanneng Power Development Co., Ltd. provided reporters with a data on the typical case of building green lighting energy saving: 160 electric incandescent lamps were used in the lighting of the community, and the annual power consumption was 25,900 kWh. If you use the same number of 11W energy-saving lamps, the annual electricity consumption is only 0.63 million kWh. Calculated according to 0.6 yuan per kWh, energy-saving lamps plus 1920 yuan invested, the total cost is 5,700 yuan, and the total cost of incandescent lamps is 15,540 yuan. The energy saving effect is obvious.
Qi Chenguang, director of the Municipal Energy Office, told reporters that Changsha has done a lot of work in the promotion and promotion of energy-saving lamps. Since the beginning of this year, the city has established a special fund reporting system for energy conservation, and issued the “The second batch of recommended power-saving technologies and energy-saving products-oriented catalogues in Changsha Cityâ€. The green lighting demonstration project will also be launched in the New River Delta and Orange Island. The introduction of these measures provides a good external environment for the cultivation and healthy development of the Changsha energy-saving lamp market. In response to the problems in the current market order, the relevant government departments will raise the supervision of the "big stick" of laws and regulations, and let the unqualified products be removed from the market; on the other hand, they will learn from the advanced experience at home and abroad. Through the government's preferential policies, we will guide the "carrots" and encourage ordinary people to use high-quality energy-saving lamps.

The printer cable is the cable used to connect the printer and the computer. Generally divided into two types: USB printing cable and parallel port printing cable.
Generally, one side is a USB port to connect to a computer, and the other side is a PIN5 port to connect to a printer. The transmission speed is fast, and it can be hot-swapped. After connecting, the printer driver must be installed to print from the computer normally.
Parallel port print line:
Refers to the printing line that uses parallel transmission to transmit data. Because this interface is easily damaged and the transmission speed is slow, it is basically replaced by the USB interface.
Serial print line:
The serial port, also known as the serial communication interface (usually referred to as the COM interface), is an extended interface using serial communication.
A printer is one of the output devices of a computer and is used to print the results of computer processing on related media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. According to whether the printing element has a hitting action on the paper, it is divided into impact printers and non-impact printers. According to the structure of printing characters, it is divided into full-shaped character printers and dot-matrix character printers. According to the way a line of words is formed on paper, there are serial printers and line printers. According to the technology used, it is divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers.
In general, the wiring harness industry is a good industry, because Wire harnesses are widely used in many fields, whether it is industrial, medical, military, communications/automotive, or computers, machines, etc. The benefits of the company are very general. How to position, what kind of wiring harness to make, and how to provide services with the whole machine, all test the ability of the factory. For this reason, Suzhou Kable-X has formulated a set of implementation methods for fast delivery and good after-sales service.
In addition to Printer Wiring Harness, and Elevator Unit Wire Harness, we also provide Medical Power Wire Harness and Vehicle Cable Assembly for these companies.
