LED lighting LED is Ⅲ - Ⅳ made ​​compounds, such as gallium arsenide , gallium phosphide , gallium arsenide and other semiconductor phosphorus , which is the use of solid semiconductor chip as hair light materials. Rare metal gallium in the modern semiconductor industry widely used, mainly in the compound gallium arsenide occurs , accounting for about 80% of total applications, gallium , gallium arsenide is mainly used in 3G mobile phones, wireless communications and semiconductor LED lighting on .

● Early export-oriented , now swept the major domestic mainstream market

● From the edge of the product to the factory main product , small congregation into the mass market category to

" 2013 LED bulb prices have done rotten. " After the 2014 opening , the reporter has no fewer than three times to hear the complaining. In fact, the situation is similar LED bulb LED downlight products as well .

2013 , LED bulb and LED Downlight LED lighting is the most fiery competitive products , the price can be said to be the phrase , " there is no minimum , only lower " words. Rush through the whole of last year 's prices , this year, these two products left much room for price cuts not yet known, but you can already predict much. This year, what products will also become the focus of competition do next ? From the current market view , LED panel lights doing my part.

The LED is a LED lighting Ⅲ - Ⅳ made ​​compounds, such as gallium arsenide , gallium phosphide , gallium arsenide phosphide and other semiconductor , which is a semiconductor chip as the use of solid fat light materials. Rare metal gallium in the modern semiconductor industry widely used, mainly in the compound gallium arsenide occurs , accounting for about 80% of total applications, gallium , gallium arsenide is mainly used in 3G mobile phones, wireless communications and semiconductor LED lighting on .

Over the past few years due to the impact of Japan's nuclear disaster , and high energy prices , global awareness for the green energy industry once again rising , the growth of related industries , he returned to the track . However, in the past more emphasis on the importance of open-source vendors have invested solar panel manufacturing and conversion efficiency improvement , but limited progress after years of efforts , has been unable to break through the bottleneck of a 20% conversion efficiency . In this case , attention gradually shifted to the energy efficiency of large-scale energy saving LED throttling , which trend began to take shape in the second half of 2013 is expected to be created from 2014 , followed by three years of explosive growth of LED lighting .

Most of the first wave of LED industry, the financial tsunami originated at the end of 2008, the Samsung LED -backlit flat-screen TVs , unexpectedly sold , opened up to 18 months of LED TVs growth cycle .

Thin LED TV penetration rate steadily increased from 3% in 2009 to 38% in 2011 . LED shares have climbed on the world's high point , every company can produce continuously open .

But Japan is Jackson , this beautiful all a huge downturn in 2011 . Five-year plan to promote the continent , the result of its large subsidies MOCVD machine , creating the continent has the largest worldwide , more than 1,000 units of MOCVD machine . Carve out a lot of production , so that the price collapse LED backlight , LED from the frozen period from the fall , the whole industry from the second half of 2011 began to enter a long period of adjustment capacity until the end of last year.

LED industry into the production capacity to adjust another reason is the rise of LED lighting industry deferred . Causes ten city streetlights plan failed , in addition to the heat problem can not be resolved outside of the bulb makers reluctant to support LED lighting is another main reason. At that time, LED bulbs expensive side , unable to attract consumers in general , is another reason not to promote .

LCD and LED LCD TVs are mainly divided into two categories . Flat- screen TV is mainly used indium tin oxide target (ITO), 70% of rare metals used in the manufacture of indium ITO. LED TV is the full use of LED (light emitting diode ) television as the imaging device , generally used for low-precision display or outdoor big screen. LED is gallium (Ga) and arsenic (As), phosphorus (P), nitrogen (N), a diode made ​​of a compound of indium (In) , when the electron and hole recombination can radiate visible light , which can be used a light-emitting diode.

Recently, the stock index has always been around 2050 points finishing concussion , the news is getting warmer : " top-level capital market redesign , 'New National Nine ' will soon be out ," This will help boost market confidence , A shares out of the bear market quagmire or near ; " March manufacturing PMI was 50.3 , ending three consecutive months of decline ," indicating rising macroeconomic or re-entered the track . In this context , the secondary market segments due to the industry boom led recovery , concern most funds.

Automotive Safety and Energy is the eternal topic of development , the core of modern automotive technology development.

Light signals are auto language timely sensitive light signals is indispensable to guarantee safe driving . While driving at night because the sight of poor judgment in front of the driver on the road to decline , the light is too bright or low light are likely to cause accidents. According to statistics the U.S. National Highway Traffic Safety Administration showed that while driving at night time only the total driving time of 1 / 4, but the proportion of traffic accidents resulting in deaths accounted for 1 /2.

In addition, the world automobile accidents statistics show that car accidents worldwide each year more than 10 million casualties , including deaths of about 500,000 . The accident occurred three times during the day and at night , the accident rate of adverse lighting conditions when the light is good times when the lighting . "Because LED lights light speed , vehicle speed and road conditions in real time to reflect , leaving motorists longer judgment time . It measured 100 kilometers per hour , the car after 7.5 meters shorter braking distance can make . Effectively prevent rear-end collision , reducing car accidents, active safety is of positive significance to improve the car . " Industry experts said . In addition , LED controllable , such as light type illumination range , linear adjustable brightness can be done , but the traditional xenon lamp to die. In recent years , LED technology continues to develop , the technical shortcomings continue to be overcome , LED lights are more intelligent. For example, some models are equipped with LED headlights on the vehicle to detect radar and control the computer , even if the driver long open beam, the encounter will be automatically reduced to the car lights and even reduce the brightness of the light type .

Energy saving is another significant advantage of the large LED lights. According to the Ministry of Planning , at the end of 2015, automotive lighting carbon dioxide emission reduction targets need to be completed . Since LED lights are cold light source with low power consumption, long life advantages , power consumption is only equivalent to a traditional lamp 1/ 10 , better fuel savings . It is reported that if the energy-saving lamps to everyday analogy , energy saving than incandescent lamps 4/5, but also energy- saving lamp LED than 1 /4. In the car , the same daytime running lights, LED energy halogen element is only 1/20 .

In addition , LED lights as well as high brightness , high temperature , small size, high stability, no radiation and other advantages, is recognized as the "green light ." Future LED will be more car manufacturers of all ages , in automotive applications also will be more extensive , LED automotive lighting market with a bright future .
