D900 led downlight: competitions from the Middle East

Technological innovation. “In theory the life of the LED chip can reach 100,000 hours, which are not empty words, a person’s life a lamp, this slogan is not an ideal lying.

D900 led downlight: competitions from the Middle East

In general, all aspects of the D900 led downlight chip performance play out will be able to achieve the ideal state. “industry experts said so. But to ensure that the method of maximizing the level of this theory is the technological innovation and progress. The relatively early timing of the large foreign corporate R and D strength, talent, and the environment in all aspects advantage, while the LED high bay lighting domestic enterprises, even if it is a listed company, do not have a strong fighting strength in key technologies and core equipment. Technological innovation is reflected in two aspects. The hands of a few large companies part of the first patents for inventions, the key patents in all of them in a few countries such as Japan, USA, Germany, while a small number of patent applications in China, and mostly belong to the peripheral technology, effect pending a new patent can not form a patent network. Followed in terms of talents after domestic institutions and there is no corresponding very counterparts in the professional setting, which led to most of the new light source associated with the enterprise management personnel, engineers and production line of talent is very scarce. Technology to determine the fundamental of the product, there is no technological progress, there will be advances in the industry, not to the external competitiveness of the capital. Thus, the domestic D900 led downlight enterprises to strengthen technological innovation, there is an urgent and important.

Prices of LED household lighting products drops tremendously

 

Market participants said the 2011 lighting industry, the initial downturn, the market generally reflects not the busy season, the off-season is more light out of a tortuous line, Guzhen LED household lighting price index in the busy atmosphere, but overall, still better than 2010, the annual lighting wholesale price index rose 19 percent.

 

Outdoor lighting series from the index, the index fluctuations in the past six months this year, the start is still unstable in the first week was 91.8, the third week fell to 81.1, the current rose to 88.4, or 5.62 percent, or where several indicators the. The light source index of the past six months the overall rise, but more volatile after the start of the year, this year the second week index was 115.7, but the second and third weeks lost more than 10 points.

 

In addition to price instability in the price index reflects the number of lighting products since the beginning of this year, according to customs statistics on lighting exports can be found in the export of such products subsequent fatigue. According to statistics, 2011 Zhongshan lamps, lighting fixtures and similar products exported $ 870 million, down 0.6 percent; in January of this year, LED high bay lamps, lighting fixtures and similar products exported $ 070 million, up sharply down 24.1%.

 

To industry analysts, the 2012 LED household lighting industry will be faced with the raw materials, high internal and external demand slowdown, industry competition and pressure, 2012 Guzhen Lighting price index will continue to show the ups and downs of prices of the traditional peak seasons for white, full-year trend steadily, but the rate slowed down slightly in 2011.

Domestic MOCVD successfully reduce the price of LED reef tank lighting

 

Domestic MOCVD successfully reduce the price of LED reef tank lighting

 

Chinese Academy of Sciences Institute of LED reef tank lighting research and the success of the LED light chip manufacturing key equipment MOCVD LED equipment manufacturers in China entered a new stage of history.

 

MOCVD metal organic chemical vapor deposition, is the key equipment of the production of LED reef tank lighting chip technology is extremely difficult, the world’s major monopolized by two companies, including Germany Aixtron with the United States Veeco’s  (Veeco’s mergers and Emcore company MOCVD business) two home.

 

Developed successful MOCVD LED Lighting Institute of the Chinese Academy of Sciences, its technical level has reached the standard of the sale of the MOCVD, perhaps to be slightly worse than the famous reserves of the new generation of MOCVD equipment, but apparently the actual business running, you can input the industrial production of LED lamps, will eventually lead to lower prices of LED lights, so that ordinary people lucky enough to use this high-tech environmentally friendly products. There must be a high temperature and pressure control capabilities, including the amount of a variety of gases control, and all this in a confined space, it is clear difficulty is much higher than automobile engines.

 

Due to the presence of monopoly and technical barriers, the manufacturers use high-priced strategy, to profiteering, a set of equipment of millions of dollars, thus the final LED chip prices remain high, transmitted to the downstream so that the price of led high bay lights also difficult to reduce, and ultimately lead to the LED lights difficult to spread, the only high-end users can enjoy this environmentally friendly energy-saving lighting products.

The influence from foreign recessed led lighting fixtures enterprises

 

The influence from foreign recessed led lighting fixtures enterprises

 

It is worth noting that foreign enterprises setting has long been walking in front of the LED standards.

 

It is reported that many international standardization organizations and enterprises attach great importance to standards. The International Electro-technical Commission and International Commission on Illumination are very concerned about the standardization work of the development of LED and recessed led lighting fixtures, Europe and the United States and other countries have their own technical standards and test methods of research. International LED companies such as Philips, Osram Long, etc. at the same time actively participate in national and international standardization work, have also developed their own business standards, standardized LED lighting broadcasting parameters, such as voltage, current, luminous flux, chromaticity coordinates, color temperature, color, life and other indicators. In early 2010, set up the lighting giant Osram, Philips, Panasonic, Toshiba Cooperation Organization-Zhaga Union, defines the standards of the various optical engine interface. At present, standardization has been basically formed, the products will also be launched in the Chinese market.

 

“In order to better regulate the market, but also for industrial development, the urgent need for the development of led high bay lighting industry standards,” said Jiang Yulong.

 

Researchers at the China Electronics Technology Group Zhang Wansheng had indicated last year, the LED state and industry standards not be so anxious. But immature before the national standards, industry associations can be of some large enterprises recessed led lighting fixtures, demonstrations, exchanges, seminars, establish a benchmark for other manufacturers to learn from, and thus lay the foundation for the development of industry and national standards.

The color mixing technique of RGB led downlight

 

The color mixing technique of RGB led downlight

 

The nature of the lighting is while, according to Ming, the light shines in the object, and objects into the eye after reflection, so the process of lighting objects on the various wavelengths of light absorption is different, and thus a solid color of red, green and blue color LED 3:6:1 mix of light and out of the white light itself there are certain color defects, exposure to the surface, absorbed on the surface of the red, green and blue, was an object, the reflection effect caused by CRI reduction.

 

Tricolor RGB led downlight color mixing technology is a more mature white lighting technology, this technique because the larger the distance between the different led high bay light mixing distance, before the LED plus mixed mask, to solve the mixed light problem, but the light loss is an obstacle to the development of lighting toward the thin obstacle. Again to watch the lighting is not uniform white; of these two factors directly restricts the development of this technology.

 

Based on the tricolor RGB led downlight mixed light technology to solve two issues started. The study found that as the distance between the LED chip to reduce the mixing of light from the decrease exponentially with increasing bulk reagent concentration in the surface coating of color mixing is exponentially enhanced, in depth study of the commencement of find an optimal balance between the three color LED chip spacing reduction and three-color reagent concentration increased, a solution the best solution of the three primary colors mixed with light, this program so that the tricolor white LED as a light source made ​​possible.

The property market downturn bring disaster to the LED household lighting industry

 

The property market downturn bring disaster to the LED household lighting industry

 

Summary 2011 can be seen LED household lighting market, raw material prices, labor costs, rising logistics costs plagued the development of enterprises. According to company projections, production costs directly to an increase of 20% to 30%. A greater pressure from the real estate policy control to deepen the weak growth in demand for lighting products terminal.

 

“Before into the wholesalers to the store will take the initiative to ask what the latest styles, met the Italian style, how much will the next single point but in the second half of last year, a lot of wholesalers into the store, Look East, West look at is less than one. “Liu told reporters in Guzhen Lighting Street operates a store, her customers are mainly from the Northeast, but most come to see prices, the housing market downturn, these wholesalers do anything, do not want to be too much money on the pressure in the purchase price.

 

With the continuing escalation of the consumption structure, people are starting to focus on the decoration of the home lighting needs of residents living in the coming period will continue to maintain a strong momentum in the domestic market demand of the LED household lighting industry within the next few years should not be any major fluctuations, especially the interior lighting industry will maintain the momentum of sustained growth, the more high-end home decoration, the greater the need for the aesthetic design of the LED high bay lamp to be against the background in order to show the design development of the real estate industry will affect the home improvement lighting market an important factor.

 

Industry awareness is not comprehensive for beta LED street light

 

Industry awareness is not comprehensive for beta LED street light

 

To the industry, and touched the overall cognitive development direction, not clear market industry technology still need to improve all restricts the development of the industry, and the enterprise put in existence, the requirements of customer demand earnings guidance dislocation, relationship market, the government chief executive problems such as consciousness within the intertwining, it is hard to make industry development. For example in the market beta LED street light, more than one LED light source combination of the canister light, LED fluorescent lamp, LED light bulb, the lighting effect and the traditional lighting products compare also has the very big disparity, just dozen LED the name, not really play in beta LED street light the strengths of the indoor lighting. The main reason is that many manufacturers can’t correct understanding of the conventional lighting illumination method and requirements of the particularity, just in gourd ladle painting, according to the conventional lighting the shape of the production, think: the same appearance is light, lights is lamp, the illumination energy conservation is the lamp. This simple idea completely ignore the LED high bay lighting advantage, indoor lighting the real requirements should be: according to the requirements and different places intensity of illumination environment standards, (intensity of illumination evenness, glare restrictions, light color, color rendering, reflex, such as the ratio of), have the comfort of soft lighting system, this study more conventional lighting source of light shine principle, make indoor illume requirement accord with the atmosphere of the lighting, lighting, emotional appeal lighting situations, meet the user’s various lighting requirements, even modelling also want to accord with the aesthetic view of the user.
