Chaoyang industry needs but not optimistic about productivity growth in demand

Semiconductor lighting in luminous efficiency, service life, volume, response speed, environmental performance and other aspects of the traditional lighting products. It has been widely used in full-color display, traffic lights, car lights, background light, landscape lighting, special lighting. The main patents and high-end products are the 5 major manufacturers in Europe and the United States control, the latter are vulnerable to the threat of patent litigation.

With the saturation of the small and medium size backlight market as well as some other existing areas of growth, the future demand growth will mainly come from the large size backlight, display and automotive applications in depth. The industry is looking forward to the use of large-size backlight 08 years lower than expected to lead to excess capacity.

09 years of growth in the number of new applications in the field of demand for the new machine is more than 07 years, while the size of the backlight on the demand for MOCVD machines in the past 09 years, an increase of more than 48 units in, a total increase of 139.3 units.

As of the end of 08, Taiwan and Mainland China to add new MOCVD machine 126 units, there will be a new expansion plan for the implementation of the new year, the supply of 09 years can fully meet the needs of the growth of the. Through the MOCVD's main supplier of AIXTRON's revenue projections of productivity growth, from the second half of 07 to the second half of the second half of the world for the production of MOCVD machine growth reached 226 units in. The industry has been through the expansion of the expansion plan to adjust production capacity growth, the next two years, the situation is difficult to meet demand.

The low cost advantage of domestic enterprises is still evident, gradually from low to high to occupy the market, at the same time as the application directly facing the huge domestic market, can reduce the risk of suffering from patent litigation, enterprises can accelerate the development of. But the excessive expansion of production capacity of industry cannot be overlooked, we give the industry neutral rating.

Semiconductor lighting is one of the most promising sunrise industries

To highlight the advantages of semiconductor lighting

Lighting industry has experienced three generations of products, they are the first generation of electric light source: incandescent lamp (tungsten halogen lamp), the second generation of electric light source: fluorescent lamps (fluorescent lamps, energy saving lamps) and the third generation of electric light source: high intensity discharge lamp (HID), is currently the fourth generation of electric light source the development of semiconductor lighting. Implementation is a semiconductor light-emitting diode semiconductor lighting (LightEmittingDiode, abbreviated as LED), is composed of P type semiconductor wafer and N type semiconductor, transition layer formed between them is called P - N P - N junction, when combined with positive voltage with current injection of electrons and holes and light. The LED chip is very small in size, usually only tens to hundreds of microns square, which belongs to the solid state light source, select the appropriate matching of materials and manufacturing processes, most of electric energy can be converted into energy, theory of luminous efficiency is 400lm/w, the maximum luminous efficiency is 157lm/w LED laboratory. LED is a new type of solid-state cold light source, which has the characteristics of high efficiency, energy saving, environmental protection, long service life, easy maintenance, small volume, fast response and high reliability. At the same brightness, the power consumption of only ordinary incandescent fluorescent lamps 1/10, 1/3, and life can be prolonged by 100 times, semiconductor lighting is one of the most outstanding twenty-first Century high technology development, the future of the semiconductor lamp will gradually replace the incandescent lamp and fluorescent lamp. By comparing the characteristics and advantages and disadvantages of the first three generations of products, we can see the strong vitality of semiconductor lighting.

Applications constantly.

LED already from the earliest indicator to the development of lighting, lighting is usually divided into general lighting and special lighting in two areas. With the continuous improvement of luminous efficiency and light intensity of LED, LED has developed into the special lighting, and gradually entered the field of general lighting.

The scope of application of LED is mainly composed of LED chip (MCD, luminous intensity and luminous efficiency (milli candela) lm/w, LM / W) decision. The greater the luminous intensity and luminous efficiency is more and more widely used.

LED chip can be divided into ordinary light intensity according to the brightness LED, high brightness LED and high brightness LED, <10mcd luminous intensity for ordinary brightness, 10mcd ~ 100mcd between the high brightness, to meet or exceed the 100mcd super high brightness. The ordinary brightness is mainly used for the indicator lamp; the high brightness is used for the special lighting; the super high brightness can be further used for the general lighting.

From luminous efficiency, LED has a three generation of lighting products incomparable advantages. The luminous efficiency of LED theory can reach 400lm/w, the current production level is 70-90lm/w, the laboratory level is about 120lm/w. The luminous efficiency of the first three generations of products are ranging from 8-80lm/w. The higher the luminous efficiency means the power to achieve the same lighting effect is reduced, and its superiority is also increasingly reflected. At present, LED has changed from the early indicator to the development of traffic lights, car lights, background light, landscape lighting and special lighting, military and other applications (toys, gifts, light industrial products etc.), general lighting has started.
