Business Equipment Manufacturers Snatch LED Stage Rally

LED lighting

Veeco MOCVD for LED device makers rush after the spring , Taiwan held a press conference , Jeffery Pina Veeco , senior marketing director will personally site , indicating that the solid-state lighting Veeco 's strategy to consolidate the market . LED lighting is expected this year, revenue jumped to the plant main and triggered a wave of expansion wave .

American and German business Veeco MOCVD Aixtron as major manufacturers , a global ranking of separation , two , two companies share total more than 90%, MOCVD equipment universal world output by these two companies , will start another promising LED lighting tidal wave of expansion , Veeco will hold a press conference on 11th of this month , news conference since the spring is also the first public 's LED industry.

According to the relevant industry estimates , in 2014 LED lighting market size estimates from the 4.586 billion dollars in 2013 to grow to $ 5.703 billion , with an average growth of about 25% , the industry is experiencing a phase of LED solid-state lighting and booming , LED chip demand being from a backlight module (BLU) mainly to transformation into a high growth of solid-state lighting (SSL) for the center of gravity. Veeco expected restructuring will drive the demand for solid-state lighting market , LED reducing costs while taking care quality and efficiency , and market size and demand better promote the development of a new generation of MOCVD equipment.

LED industry suffered under the first two years of oversupply attacks , resulting in 2011 , in 2013 the global LED equipment owned , respectively, dropped 45% to 30% this year, pushing up demand in LED lighting , the United States this year to ban incandescent bulbs , LED lighting demand will off, is expected to drive LED devices owned a re- entered the track to grow this year .

This year each LED lighting plant were significantly enhance the proportion of revenues , the proportion of revenues are expected to fall about 20 to 40 percent , Ronda , Formosa Epitaxy are expected to exceed 40% , Everlight also estimates is expected to exceed 30% ; in view of the overall market this year, the output value of LED lighting will also be the first time beyond the backlight .

LED Lighting Industry Will Produce What Kind of Pattern Change?

LED lighting

As a light source for illuminating the material basis of traditional light LED light source will be the mainstream , this is not to say that 10 years ago the basic , but very few people do not believe now estimate the . As the influence of the surface of mainstream LED light source is the impact on the industry , but also for the development of large lighting disciplines .

Since before the LED, the light source is a major source of thermal radiation , low pressure discharge light source and high intensity discharge light source , and the main purpose of which is the visual light illumination ( To be consistent with the existing version , this paragraph will be referred to the visual illumination lighting ) . These light sources , such as scales due to the flexibility , spectral and time and space , creating a center of gravity lighting disciplines is the material basis lighting " light " in the light of the study , after mature , there will be no big lighting basic disciplines of development. We see that the lighting disciplines in first half of the 20th century, there are a lot of research , but in the CIE1931, CIE1964 and CIE1976 chromaticity system , the last time in 1974 after the great progress that CRI finalized, lighting no major progress in basic subjects even fast approaching , " lighting " of the. This is mainly the material basis illumination is too inflexible , and in other words , it is that several sources , their application can be thoroughly studied . Therefore , after major research is the development of a new light , and thermal radiation source as the main gas discharge light source after , the focus of research to find new luminescent material , or the second light emitting method . But LED illumination into the mainstream , will make a great change in this situation :

When the main indicators and price (1) LED device technology has not yet reached maturity, especially the green LED pending further technological progress. Thus , over time , the development of LED technology will continue to be an important part of our lighting disciplines. However, the current LED has been developed to be able to get the application in many fields. Therefore , the focus of the lighting disciplines will gradually return to the lighting , the light source of the application, but not the light itself.

(2) LED high degree of flexibility will create tremendous research opportunities for future lighting disciplines. Because , LED high degree of flexibility to create a wide application field of LED , and in a variety of applications , is the high flexibility of the LED there is an optimal choice of applications , it is an academic problem that research opportunities . A typical example is the fill light LED plant , the presence of the human eye due to the different wavelengths V (λ) values ​​are different like , plants are also different fill fill light efficiency of different wavelengths of light , ie there is a concept of a light formulation . The current study is still in its initial stages.
