Led versus fluorescent will open up a general lighting market

25 Jun

Over the past forty years, led strip lighting industry is always the revolution of science and technology information striker, become the industry and the focus of attention of the capital market, led industry means striking the benefits of active: use new technology process of continuous innovation to build the smaller, faster and cheaper led lighting products.

With the improvement of LED manufacturing process and the development of new materials, its application scope expands unceasingly.
led tube fluorescent are about to hit a third round of general lighting bring growth cycle. LCD back lighting is the main driving force, general lighting times ahead. Conventional lighting market 70 billion us dollars, is back light 12 times of market and to 2020 dollars; Drop in cost is the key to open the general lighting. LED lighting has the lowest cost, but cost more than nine years of reply. The cost of less than 2 LED backward to 3 years. The market is lighting outbreaks.
LED market advance to see that started in 2000 LED the promotion of the mobile phone that fast growth of around 44%, the market started in 2005 saturated. The second round of growth was mainly coming from the application of LED backlight, began in 2007. The third round growth was predominantly general lighting market start. Our concern is the market at the open.
Expected after 2014 back light market will be regional saturated. We think the time node is likely in advance, so led versus fluorescent lights industry to the further development of words, need to get another breakthrough, the breakthrough is general lighting market, in 2010, the general lighting market probably at $70 billion.
Soft light from LED with the cost structure, and other lamps and lanterns to see, LED mainly includes LED chips, extension and so on, we think that the cost will follow the following LED five path, to 2015 is expected to drop 86%. The cost of LED decrease of 20% per year, a single encapsulates the luminous efficiency and flux every 24 months double, and 2010-2015 warm white LED the luminous efficiency increased by 135% and the corresponding costs fell by 57%.
LED lighting and a decline in the cost of technology of ascension that will make it in the overall lighting market to get better and faster development, the future will be greatly enhanced the total performance.

led strip is a high-grade indoor lighting lamps and lanterns, outside its borders by anodic oxidation by aluminum alloy and become, for LED light source, the whole design is beautiful lamps and concise, atmospheric luxury, both good lighting effect, and can give a person to bring a beautiful feeling, for consumers love.
In the light of the panel of LED, the most important is the dynamic power supply. LED to the requirements of the power supply device driver near demanding, LED unlike the regular incandescent light bulbs, can be directly connected to 220 V ac utility. LED is 2 ~ 3 v low voltage driver, must want to design of complex transformation circuit, different USES of LED lights, equipped with separate power adapter.
Along with the progress of the technology industry LED and ascension, brightest led strip of drive technology also has been big advance. LED panel lamp drivers power constant current control technology progress, mainly in the following aspects:
1) chip peripheral control circuit of simplify ceaselessly, the constant flow technology level side (PSR) has been increasing maturity;
2) chip constant current precision improved, and to reduce the production of deviation, improve the reliability of the power of mass production provide strong guarantee;
3) are the LED illumination special single stage APFC chip to emerge and mature technology, make LED panel lamp power the size and cost of further down.
At present, the LED panel of the power transformer of lamp drivers, inductor parameter of the demand is extremely high, for the sake of precise need to spend a lot of money and manpower to achieve, industrial production cost is hard to further down. Through to the LED panel lamp drivers constant current source chip design technology innovation and breakthroughs, new solutions can be LED lamps in driving power practical application, the output current for transformer and inductor inductance of the quantity and the parameters such as VF LED too sensitive.
bright led strips constant current drive power of another hot trend is including automatic high power factor compensation, low harmonic of the solo stage APFC control chip. The United States energy star standard for 5 W above with solid state lighting specific clear pf the requirements of value. So, this year to the LED illumination lamps of a single chip manufacturer APFC level of demand increase greatly. New LED lighting special single stage APFC scheme is plus LED lighting lamps and lanterns trade demands.
With the continuous development industry LED panel lights and other countries to introduce the energy standard, and ensuring efficiency of conversion, under the premise of LED panel of the development of the power supply will continue to move in a small volume, less components, higher precision, is more advantageous to the production the direction of development, therefore, new power chip constant current control technology, and single stage APFC technology further improvement of mature, LED lamp panel for the promotion and the power performance cost down, a decrease in the size of the play a very significant role.

Juno led downlight industry at the shuffle

20 Jun

led strip lighting market demand for raising temperature, in 2011 the size of the market is expected to reach annual growth of the above, along with the LED lighting is regarded as the most robust growth LED industry future application market, all LED lighting of the layout of the company in field will become the next wave forces the key industry growth, at present, the LED upstream of the grain industry LED lighting of revenue in the proportion of whole about 2 ~ 3 into, but FengZhuangChang downstream steps of progress is differ, benefit is relatively slow appeared.

According to the market estimates that 2010 year led 12v downlight penetration rate in about 4% ~ 5.5%, and 2010 year LED lamp hair smooth effect though rate and fluorescent lamp is consistent, but 2011 years is expected to challenge the permeability 10%, luminous efficiency also have a chance to increased by 20%, and transcend fluorescent, because incandescent lamp gradually into medical history and government subsidies to promote factors, LED lighting gradually from the past (the type used, for example, to reveal ark lamp, plant floodlight lamp, medical treatment, and began to walk into the commercial, household Lord lighting market.

Part of the value of kitchen led downlights industry development potential, 2010 have aggrandizement illume layout, and with the TV in the fourth quarter turn back lighting demand light, also make the proportion of LED lighting growth, it is estimated that 2010 years the proportion of crystal electric lighting will reach 2, 2011 is expected to grow to 3 into, and Thai valley in the fourth season high power lighting is hopefully increase the proportion of to nearly, the ladies in the fourth quarter is expected to round to the proportion of 3 into lighting.

But LED FengZhuangChang bibcock in 2010 though light lighting launched their own brands, but the main business is still lay particular stress on the backlight application, the proportion of lighting. Only about 5% ~ 6%, and although that 2011 m light lighting business have the opportunity to grow multiples, is expected to contribute $1.5 billion revenue, accounting for about 10% of overall revenue levels, but still belongs to the low proportion of lighting, compared with 2010 YuDongBei points out that LED lighting products revenue of about 1 billion to 1.1 billion yuan, the scale has surpassed light, on the mainland in 2011, Europe, the us and Japan market surge in order, 2011 LED lighting revenue is expected to reach 2 billion-2.5 billion yuan, and rising stars YiDiSen is specializing in high power LED lighting, maintain the 3 gross margin, potential development is after is good.

With the new competitors are joining the market, recent foreign legal person named light, etc FengZhuangChang possible future expansion in traditional strong customer base face difficulties, or even lose their industry’s leader, in addition because downstream encapsulation competition is intense, is expected to ship in 2011 average unit price decline could LED, gross margin and impact. LED companies have argued that the TV back lighting and lighting will be in the future growth of the twin-engine =, but TV back lighting is in the next two to three years later the bottleneck facing growth slowed sharply, and LED lighting will be pulled the continued growth of kinetic energy of important industry, now LED lighting is embryonic stage, the future industry still has a fierce competition, the anticipated market forces will face the shuffle.

LED industry detailed control parameters

Article 1

For nearly 30 years, led strip lighting technology experienced a rapid development process. LED to its inherent high efficiency, long life and low loss, vibration resistance and response speed advantages such as a wide range of applications, such as a lamp, screen, traffic light and so on, are currently exploring it is applied to the lighting area.

Because China has not establish LED photometric standards, severely affecting LED quality improvement and the values of quantities of unity, affecting international trade and international technical communication between LED and promotion, therefore, although in recent years the Chinese quality and variety LED products have improved, but the gap with foreign advanced countries is obvious.

In this situation, we set out for the measurement of optical parameters LED the meticulous research, and LED the establishment of national photometric standards.

2, the LED Tube parameters are introduced

LED optical parameters of the important aspects in is: Flux, the luminous efficiency, luminous intensity, light intensity distribution, wavelength.

2.1 are The luminous efficiency and flux

The luminous efficiency is the ratio of the flux and power. The luminous efficiency represents the light source of energy savings of characteristics. It is to measure performance modern light source is one of the vital index.

2.2 are The luminous intensity and light intensity distribution

flexible led strip lighting luminous intensity is characterized in a direction of its luminous intensity, due to the different space angle in led light is quite different from that of strong, and we studied the light intensity distribution characteristics of bed. The parameters of practical significance are very big, directly affect the LED display device of the smallest view. Such as the sports facility LED large color displays, if choose LED single pipe distribution range is extremely narrow, so in the face of the larger screen angle viewers will see the image distortion. And the traffic signal lights also demand is bigger range of one can identify.

2.3 wavelength

For LED spectral characteristics we basically see its monochromatic is fine, but also to pay attention to the red, yellow, blue, green, white LED and so on main color is pure. Because in many cases, such as the traffic lights to the color is asked to compare strictly, but according to observe some Chinese LED light now in some green, red for scarlet, from this phenomenon come to see us LED the spectral characteristics of special study is very necessary and very interesting.

3, LED photometric measuring principle

3.1 are The light intensity measurements

The light intensity standard light, LED and equipped with V (λ) filter silicon photoelectric diode installation and debugging in optical benches, especially strictly the filament position, LED parts and accept surface location.

For LED speaking, its shiny surface is the shape of the dome, light distribution is very special, so in different distance is measured, light intensity value will change from inverse distance square laws, even if fixed distance is measured, but because the receptors to accept different area, the light intensity value will also change. Therefore, in order to improve the measurement precision, should the distance is measured and accept area size to give relatively fixed as well. For example, distance is measured according to GIE recommends the 316mm, receptors area for 10 x 10mm fixed. In the same distance is measured. LED the corner is different, its brilliant light will be changed, so in order to get the best value, had better read the maximum readout Rt is preferred.

3.2 flux measurement method

Measuring leds luminous flux in angle changed the photometric on the turntable, installing the LED on the table, the table in the horizontal plane around the vertical axis rotation + 90 degrees, LED in the perpendicular plane around the metering axis rotate 360 degrees. the horizontal plane and the vertical plane of control is through the rotation of the stepping motor to fulfill. Turntable in guide rail move, when measuring standard lamp, turntable should leave guide.

When be measuring the big wheel in a perpendicular shaft revolves around a horizontal plane, step angle of 0.9, 90 the positive direction, 90 in the opposite direction. LED oneself moreover is in rotation, in every level angle, the vertical plane every 18 a signal acquisition, turn over 360 samples were collected after 20 data, press type calculating total flux.

Absolute flux measurement LED the second kind of method is integral method. This method is simple and feasible, but the measurement precision is not high.

The spectrum of light emitting diode power distribution measurement, the purpose is to keep the spectral characteristics and LED chromaticity, moreover is measured in order to have LED luminosity an amended.
When measuring spectrum power distribution LED, attention shall be paid to the following, in a standard irradiance spectra and comparison of solar spectrum because standard light intensity much better than LED, in order to avoid this problem, the best in the standard before the lights and a neutral filter, make its solar spectral intensity close to LED.
The spectrum width LED was exceedingly narrow, in order to accurately describe the spectral distribution LED outline, had better use the width of monochromator narrowband wavelength measurement for 1nm wavelength interval for good.

4, last word

At present, the LED country photometric standards established and calibration equipment has been quite a number of standard LED tube, in the process, we have accumulated a lot of experience, and then we will at all levels and the comprehensive measuring department LED production units for dissemination, unified supervision. This LED to the quality of China will increase the level of play a role in promoting, also for countries in the field of high technology research and development from a to provide security.

LED illume will develop into competition of core of market of lamps and lanterns considerable

16 Jun


Face tremendous market opportunity and competition of so mad market of lamps and lanterns, the led tube lamp enterprise of world big shop sign is increasing strength of research and development, new technology gains revolutionary headway ceaselessly, the pace that LED lighting engineering innovates is being accelerated ceaselessly. Seek the fixed position in allowing to consolidate in lamps and lanterns the market competes.
Currently, the industry that LED Downlights industry already formed the 3 sufficient tripartite balance of forces that are dominant in 3 large area of the United States, Asia, Europe distributings with competitive pattern. The day on international inferior the forestall of 5 big tycoons such as riverside of acute of synthesis of cropland of chemical, abundant, division, flying benefit, Ou Silang high-end product market, this 5 big companies have distinguishing feature each in product and market respect, formed the industrial chain with complete LED. They use their the innovation advantage in new product and new technology domain, basically be engaged in the production of product of high additional value.
Each country government drafts environmental protection code actively, taboo incandescent lamp. Additionally, be worth what carry is, industry of LED of Chinese Taiwan area rises quickly in recent years, its chip crop and enclose crop to hold world first position. Data shows, the market share of product of our country of Taiwan is in the world 60% above, but its product class still cannot enter the first echelon formation.
LED illume already made the technology that gets attention quiet and industry quickly. In the meantime, each country government drafts environmental protection code actively, in the market and could double benefit stimulation falls, dimensions of global LED industry shows the sign of rapid growth.
The benefit clearly that led floodlights produces. Australia published code of taboo incandescent lamp at the first. The European Union also concerns the code that washes out the incandescent lamp it was being passed in March 2009. Accordingly, the last few years accelerated Ou Silang of company of on international two big conventional lighting and flying benefit riverside to be in the layout of LED illume domain. They enter the rapid development that promoted LED illume market, also quickened the pace that LED technology progresses at the same time. LED illuminative advantage is self-evident. Glow efficiency of LED lamp is very tall, life is very long, its glow efficiency can achieve fluorescent lamp 2.5 times, 13 times of incandescent lamp. Glow efficiency of an incandescent lamp is very low. The light energy of electric energy translates into of 5% only. The electric energy of 95% turns heat wave into cost. As the LED estate rapid development in illume domain, hope of conventional lighting tycoon makes illume product through introducing the design of new light source richer innovation sex.
Amplitude of rising market in Russia is as high as 166.8%. South-American market amplitude is made an appointment with 121%. Amplitude of the middle east market also is achieved 43%. Africa is added fast relatively slow only 14%. In each in a rising market, only eastern alliance market exit does not rise to fall instead, then last year the corresponding period dropped 8.6%.

Current lamp acts the role of the problem that the industry exists, basically express consciousness of strategy of long-term now development not strong, eager for quick success and instant benefit lack of quality of outstanding, product dominates action effectively, with exporting low end the market is given priority to, market competition ability is weaker, these since help the focal point that help up and superintends, also be industrial structure optimizes the difficulty in upgrading and focus. First half of the year, suffer international economy to anabiosis influence of interest good factor, shoeshine lamp acts the role of product exit to grow substantially compared to the same period, but in exporting a process, product quality lack is controlled effectively, with exporting low end the market is given priority to, market competition ability is weaker wait for a problem still relatively outstanding.shoeshine examines quarantine bureau from 2009 since second half of the year, the side that increased opposite to produce a business namely helps strength, union pushes new classified government measure, in a planned way, specific aim sends business backbone to help the enterprise searchs a question and suit the remedy to the case, encourage an enterprise to take the route of quality, brand. Since 2008, suffer market of high end of the United States, Europe to encounter second borrow crisis of the crisis, Greek credence to wait for an influence, many electric illuminant and enterprise of lamps and lanterns are developing Zhongshan with in low end the middle east that the product gives priority to, South America, east when alliance area, satisfy client low requirement blindly to seek profit, reduced the integral quality that exports lamps and lanterns. Among them, issue of energy-saving lamp, outdoors lamp, LED lamp is relatively outstanding.
