LED - a bright light source

According to the survey of recent market research agency iSuppli and StrategiesUnlimited company, in 2011 the total LED market will reach $9 billion, of which the main growth points or more than 83% growth will come from high brightness LED products demand to promote the expansion of emerging applications, including for identification and display, car interior lighting and general lighting etc.. In addition to the LED market forecast, StrategiesUnlimited also predicted that the high brightness LED driver chip market will grow strongly, and is expected to exceed $1 billion 900 million in 2011. This is a good opportunity for the semiconductor industry to participate in the market transition of lighting technology to higher efficiency and high brightness LED conversion.

High brightness LED allows us to develop a series of new applications never imagined before.

The strong growth of the market is based on the premise of LED suppliers through the material, process and packaging technology breakthrough to improve the performance of high brightness LED significantly improved. The novelty of LED itself is also a major factor in its widespread acceptance. As a new solid state transistor to cause changes in the application of electronic industry as Egypt turn the world upside down, round (Egyptian 'wheEL') effect of drainage system for all human beings, LED will revolutionise the entire lighting industry.

Long life LED (usually up to 50000 hours or 11 years) is currently on the market of any other lighting technology can not match, this figure makes use of the traditional incandescent lamp life inferior by comparison of 1000 hours and 8000 hours of compact fluorescent lamps.

LED lamp is 5 to 10 times higher than traditional incandescent lamp. To 1W power, the white LED light emitting tube is about 100 lumens, while the traditional incandescent bulbs can only issue a 10 lumens. From the point of view of energy saving, LED lamps consume less than 10 times the cost of light bulbs. LED is undoubtedly more environmentally friendly lamps.

The standard for measuring lighting quality is the appropriate color gamut or color rendering index (CRI). The maximum value of color rendering index is 100, which is also the color rendering index of sunlight. CRI can be used to measure the degree of fidelity of an object in a certain light compared with that of the sun. After the design of the appropriate mix, LED color rendering index can be close to 90.

The mixing effect of instant transformation ability of LED so that LED can provide wonderful colors or different brightness, this feature is also compared to other existing lighting technology -- even though the neon lights we know. LED compact size, and allows us to develop a series of new applications never imagined before.

In order to meet the huge potential market for the development of new LED application needs, Avnet design services and segment marketing team to develop a variety of reference solutions, with lights are lighting solutions from street lamps and lights and general lighting to the color changing of building decoration and signage. These mature and reliable solutions shorten the time for end users to put their lighting products on the market.

The team director Mr. Huang Changguo said: "the design or installation of lighting project in helping customers, Avnet will adopt methods of system. Thermal, functional, optical and color factors must be taken into account in the design, so that LED lighting can get the best performance and achieve the desired results. "
