The price of LED lighting in the dark

In 2011, the industry generally released the doubts that the global LED epitaxial chip production competition in 2010, especially China, may cause oversupply in the market this year. Based on the decline in the price of LED luminaires and their popularity, Samsung and many LED application vendors in China have stepped into the LED lighting market. As early as 2010, Japan's first-line makers such as Toshiba and Panasonic led the Japanese government to cut prices of LED bulbs and set off a price war. Recently, South Korea’s Samsung LED Co., Ltd. announced the launch of five new types of high- and mid-power LED products with output power exceeding and below 1W, which officially entered the LED lighting market.

At present, the LED industry generally estimates that the penetration rate of LED lighting in the world will be about 3% compared with that of 2010. In 2011, the LED lighting penetration rate is expected to reach 6 to 10%. Zhong Bin, the general manager of Zhonglong Transportation, told reporters recently that the upstream MOCVD machine platform will have five-fold growth in 2011, which will inevitably lead to 15 times capacity expansion. The backlight source is the best release for this year's expansion capacity. If the backlight growth this year is as expected, LED prices may hold. On the contrary, after June, with the excess capacity of the upstream chip, the overall LED manufacturing cost will drop by 30%. At present, they have felt that there are pressures on inventory of several major international chip giants that have long-term cooperation with them.

For LED lighting manufacturers, the decline in LED prices is a positive effect, which can make their products more acceptable to users, and they also improve the efficiency of light to reduce costs and gain market profits. Chen Bin to senior engineers LED reporter said. Gaogong LED Industry Research Institute (GLII) estimates that under the trend of reducing chip costs in 2011, LED bulb prices will continue to decline, and large-size LCD backlights and LED lighting are expected to become the twin engines for promotion.

Fiber Optic Adapter

Fiber optic adapter are used in fiber optic connection, the typical use is to provide a cable to cable fiber connection. People sometimes also name them to be mating sleeves and hybrid adaptors, mating sleeves means this fiber optic adapter is used to connect the same type fiber optic connectors, while hybrid adaptors are the fiber optic adaptor types used to connect different kinds of fiber optic connectors. YLTelecom`s fiber adapter provide reliable solution for fiber connections, single mode fiber optic adaptors and multimode fiber optic adaptors available on request. We adopt high quality raw materials and make these fiber optic adapters strictly according to international standard, this makes our fiber optic adaptors with high performance.
Fiber Optic Adapters FC, SC, ST, LC, MT-RJ, MU, E2000, FC/APC, SC/APC, LC/APC, E2000/APC, Simplex, Duplex, Quad, mating sleeves, hybrid fiber optic adapters, Single mode fiber optic adapters, multimode fiber optic adapters are all available.

Fiber optic adapters (also called couplers) are designed to connect two fiber optic cables together. They come in versions to connect single fibers together (simplex), two fibers together (duplex), or sometimes four fibers together (quad).
Adapters are designed for multimode or singlemode cables. The singlemode adapters offer more precise alignment of the tips of the connectors (ferrules). It is ok to use singlemode adapters to connect multimode cables, but you should not use multimode adapters to connect singlemode cables. This can cause misalignment of the small singlemode fibers and loss of signal strength (attenuation).

When connecting two multimode fibers, you should always make sure they are the same core diameter (50/125 or 62.5/125). A mismatch here will cause attenuation in one direction (where the larger fiber is transmitting light into the smaller fiber).

Fiber optic adapters are typically connecting cables with similiar connectors (SC to SC, LC to LC, etc.). Some adapters, called "hybrid", accept different types of connectors (ST to SC, LC to SC, etc.). When the connectors have differing ferrule sizes (1.25mm to 2.5mm), as found in LC to SC adapters, the adapters are significantly more expensive because of a more complicated design/manufacturing process.
