What is the market for LED bulbs in 2017? Let’s go to the lighting market to see that last year, the stores selling LED bulbs mainly sold lamps, and LED bulbs accounted for a small percentage, less than 25%. This year, almost every home lighting store has more or less LED bulbs, and some are LED bulbs as the main lighting fixtures, becoming LED bulbs, since the second half of last year, with Chu Dealers of the LED electronic negotiation LED bulb business have been increasing. The rapid development of the LED bulb lamp market is naturally related to the substantial price reduction of LED bulbs. In 2011, a 1.2-meter T8 LED fluorescent tube would cost about one hundred yuan to buy, but now it has dropped to several tens of dollars. 3W LED bulbs, need to be tens of dollars two years ago, now only a dozen yuan can be bought, even less than ten yuan in Taobao shop, so, now, LED bulb prices and energy-saving lamps The price is almost the same, which lays the foundation for LED bulbs to enter the civilian market. For the majority of consumers, everyone is increasingly agreeing with this new thing in LED bulbs. Professional terms such as light effect, light decay, color temperature, and indexing will also come out of people's mouths. From the above information, the rapid entry of LEDs is 1-2 years earlier than expected, but is it true? Outbreak? In fact, there is no real explosion. First of all, LED technology still has a lot of room for improvement. The luminous efficacy of LED chips is increasing at a rate of 15% per year. The current light efficiency has risen to 110 lm/w. It is reported that The upper limit of one stage is 275 lm/w, so it takes about 5 years to really rise to this light effect. It takes a long time to get into the full ripening period of the LED bulb. In addition, the LED industry standard is difficult to formulate, the brand is difficult to form, and the price is difficult to unify, so it is still a long development machine, and gradually developed. Therefore, LED bulb manufacturers do not have to wait for the so-called explosion period, but should improve their internal strength, improve management and technical level.
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.
