For the market of light-emitting diode (LED) lighting market, Xinqimei, AUO, TSMC, UMC, Hon Hai, Delta and other domestic large groups have strengthened the vertical integration of their LED supply chain, plus Korean manufacturers plus code Under the investment, accelerate the penetration rate of LED lighting market, LED lighting business opportunities will be detonated in advance in 2010.
Huang Yalin, a researcher at the Optoelectronics Research Center of Tuoba Industrial Research Institute, pointed out that mainland China and Taiwan manufacturers are highly competitive in the market for LED lamp specifications and prices.
Huang Yalin, a researcher at the Optoelectronics Research Center of Tuoba Industrial Research Institute, analyzed that in 2009, Xinqimei and AUO two domestic panel factories began to actively deploy their LED industry chain, so that the vertical integration of LED supply chain is the most complete, and TSMC, UMC, Hon Hai, Delta Electronics, Powerchip, Datong, Guangbao Technology and other domestic large groups are not allowed to compete, injecting large sums of money into the LED lighting market, and trying to find the most suitable products to enter the new business map. .
In 2010, large and medium-sized LED backlights set off a market boom, and Taiwanese factories rapidly expanded their production capacity, which led to a surge in LED supply for lighting. It is estimated that Taiwan's upstream epitaxial plants such as Jingyuan Optoelectronics, Yuyuan, New Century, Guangjia, and Thai Valley, Kellett, Ronda, etc., the number of MOCVD machines can reach 137, and the shipment of medium and large backlight LEDs will increase by 7.4 billion; other applications such as lighting will grow by 100. Three and five billion.
It is worth noting that, similarly optimistic about the prospects of LED lighting, South Korea's LED epitaxial plant expansion is in rapid progress, fearing that there will be an excessive supply of LED epitaxy, which will lead to a rapid decline in LED prices. Observing the number of additional machines such as Samsung, LG and Seoul Semiconductor, it is expected that in 2010, Korea's upstream epitaxial plant is expected to expand 113 MOCVD machines, medium and large backlights. LED shipments increased by 6.78 billion units; other applications such as lighting increased by 11.3 billion. Huang Yalin believes that in 2010, Korea's epitaxial plant will accelerate production expansion, and the production capacity will be opened in 2011 at the earliest. It will have a big impact on Taiwan's LED factory. However, after the full-scale LED epitaxial production capacity in Taiwan and Korea in 2010, LED can be used. It is hoped that another wave of declines, especially for lighting, mobile phones and other applications that do not require LED chip quality, will help expand the scale of the LED lighting market.
Biconvex lenses are a simple lens comprising two convex spherical surfaces, generally with the same radius of curvature. Being a kind of simple lens, the biconvex lens has a wide range of applications of it, but it is not limited to, control and focusing of laser beams, quality imaging and also the other kinds of optical instruments.
In a biconvex lens or a Plano-convex lens, a collimated or accurately parallel beam of light passes through the lens and converges at a spot or focus coming behind the lens. In such a case, this lens is known as a converging or positive lens. The distance coming from the lens up to the spot is called the focal length of the lens. Since there is a curvature on both sides of the lens, there will be around two focal points and also two centers. The line that is drawn through the middle of the biconvex lens is known as the principal axis.
Biconvex Lenses- Uses & Applications
These lenses have around a number of uses of which some of them are listed below-
- Biconvex lens are used as a magnifying or condensing lenses.
- They are also used as objectives or magnifiers
- These are utilized in many imaging systems such as the telescopes, monocular, microscopes, binoculars, cameras, projectors, etc.
- These are used in producing the virtual image in case of a human eye and a real image in case of the photographic films or an optical sensor
- These lenses are also used as a burning-glass.
- These are used in the applications of image relays and also in various kinds of industries
- Hence, a biconvex lens is one of the best lenses that can be used in a condition where a beam of light incident on lens is diverging in nature and also the beam that leaves the lenses converges symmetrically.
