However, the reporter visited the Jinan market and found that although energy-saving lamps have become the “main†lighting for most large-scale supermarkets, some small hardware stores and supermarkets still sell. At the same time, in many online stores, incandescent lamps are still "over-age service." “Since the eradication of incandescent lamps in the country last year, incandescent lamps have gradually disappeared from such large supermarkets, and they are all energy-saving lamps.â€
In a supermarket lighting area, a staff member told reporters that, relatively speaking, energy-saving lamps have high profits and long service life. Later, during the visit, the reporter found that the energy-saving lamps have become the "main light" of most large-scale commercial supermarkets, and no incandescent lamps have been found. However, in some small hardware stores and supermarkets, incandescent lamps above 100 watts are still being sold or "sneaked".
In a hardware grocery store near Industrial South Road, when the reporter asked if there was a 100-watt incandescent lamp, the owner of the store, Mr. Zhang, immediately signaled the clerk to take it on the shelf. He said that he had not heard of the news that the 100-watt and above ordinary lighting incandescent lamps were banned from this month. "It has been sold for so many years. Now it mainly supplies nearby construction sites and production enterprises. One or two yuan for this thing. One, they also want to save costs. Because there is no energy-saving lamp to save electricity, residents in the neighborhood have bought very little."
In the high-tech zone, a small and medium-sized supermarket lighting counter, the reporter saw that a variety of energy-saving lamps and LED lights became the main counter, but more than 100 watts of incandescent lamps are still "sneak" to sell. When the reporter asked if there was a 100-watt incandescent lamp, a staff member of the supermarket dragged the box containing the incandescent lamp out of the shelf. "It’s all here! These goods are not sold out before. Now the country is forbidden to stand on the table."
In fact, on October 1, last year, the National Development and Reform Commission, the State Administration for Industry and Commerce and other joint announcements on the gradual ban on the import and sale of ordinary lighting incandescent lamps clearly stipulated that in order to improve energy efficiency, protect the environment, and respond to global climate change, since October this year. From the 1st, the import and sale of ordinary lighting incandescent lamps is gradually banned. In the announcement, it was clearly stated that the period from November 1, 2011 to September 30, 2012 was the transition period for the deflagration of incandescent lamps; from October 1, 2012, the import and sale of ordinary lighting incandescent lamps of 100 watts or more were prohibited.
Antenk DVI Series Digital Video Interface connectors are the standard digital interface for flat panels, video graphics cards, monitors and HDTV units. This series includes DVI-D (Digital), DVI-A (Analog) and DVI-I (Integrated Digital/Audio). Their unique crossing ground blades provide high speed performance at low cost. They are available in Straight or Right Angle PCB mount receptacles and mating male cable connectors. They support a data transfer rate of 4.95Gbps with a dielectric withstanding voltage of 500VAC. Each version features our specially designed contacts which improve signal performance and a zinc alloy shield that reduces electromagnetic interference (EMI).
Digital Visual Interface Cable Connectors
DVI ConnectorWith the advent of technologies such as DVD players, high-definition televisions, and even digital cable, the need for more advanced cables and connectors has increased. Digital Visual Interface (DVI) is one response to the growing need for interconnected systems, enabling digital systems to be connected to an array of displays. Yet DVI cables and connectors can also be complicated, and may lead to confusion between High Definition Multimedia Interface (HDMI) and DVI. Although the two systems have much in common, they service different niches of digital technology.
Digital Visual Interface
Older systems aren`t necessarily outdated systems. Although DVI preceded HDMI, it`s still widely used in both business and domestic settings. DVI connectors are designed to handle digital data transmission, incorporating three transmission channels in every connector link. The maximum bandwidth for data transfer is 165 megahertz, which is enough to relay up to 165 million pixels per second. Data is encoded for effective transfer, but a single link can handle around 4.95 gigabits per second of information. Double links can handle twice that amount.
Because a DVI cable carries information over a 165 megahertz bandwidth, complete digital resolution can be obtained. Using double link connectors increases the speed of transmission, but requires another cable. However, not many devices depend solely on a double link DVI, so this technolgy can be used on an as-desired basis.
Types of DVI Connectors
There are three general categories of DVI cable connectors: DVI-Digital (DVI-D), DVI-Integrated (DVI-I), and DVI-Analog (DVI-A). However, most connectors fall into one of the first two groups.
A standard DVI Connector is 37 mm wide and has 24 pins, 12 of which are used for a single link connection. When analog is involved, four additional pins are needed to support the additional lines of an analog signal. It is not possible to cross from a digital source to an analog display or vice versa. In those instances, an integrated connector is probably the best option. There are five common types of DVI connectors.
DVI-I Single Link
This kind of connector has three rows, each with six pins. There are two contacts. Because the connector is integrated, it can be used with both analog and digital applications.
DVI-I Dual Link
A DVI-I dual link connector can also be used with both digital and analog applications, but is configured with more pins to accommodate a dual connection. There are three rows with eight pins each, as well as two contacts.
DVI-D Single Link
Specifically designed for digital applications, a DVI-D single link connector has three rows of six pins, and looks much like a DVI-I single link connector. However, a DVI-D connector has no contacts.
DVI-D Dual Link
Also made specifically for digital applications, a DVI-D dual link features more pins (three rows of eight) for dual connections. Like a DVI-D single link, a DVI-D dual link connector has no contacts.
DVI-A
This particular type of connector can only be used for analog applications, and has three rows of pins. One row has five pins, one has four pins, and the last row has three pins. Like single link connectors, a DVI-A link connector has two contacts.
