where can i buy led bulbs in High Power LED Lights

To get a high-power LED street light, it is necessary to prepare a suitable high-power LED chips. where can i buy led bulbs? Usually the manufacture of high-power LED chips are summarized as follows:

where can i buy led bulbs in High Power LED Lights
① large size. By increasing the effective light emitting area and the size of the single LED, to promote uniform current distribution in order to achieve the desired luminous flux through the TCL layer. However, simply increase the light emitting area can not solve the heat dissipation and light, and can not achieve the desired luminous flux and the practical application of effects.

② silicon backplane for flip-chip. First prepared for eutectic welding of large-size LED chips, while preparation of the corresponding size of the silicon backplane for eutectic welding deposit conductive layer and leads to a conductive layer (ultrasonic gold ball solder joints), and produced in the silicon backplane , eutectic welding equipment will be large-size LED chip and the silicon base plate welded together. Such a structure is more reasonable to take into account both the light taking into account the heat dissipation problem, which is the mainstream of high-power LED production.

③ ceramic substrate for flip-chip. The first use of the LED chip general-purpose equipment to preparation of a has a suitable Total crystal welding electrode structure large a light area of ​​the LED chip and the corresponding ceramic base plate and the ceramic substrate produced a total crystal welding conductive layer and leads to conductive layer, then the use of eutectic soldering The equipment will be large-size LED tubes chip and the ceramic base plate welded together. where can i buy led bulbs? Such a structure is taken into consideration the light taking into account the heat dissipation problem, and the ceramic substrate of high thermal conductivity ceramic plate, the cooling effect is very satisfactory, the price is relatively low, so a more appropriate substrate material, and can for the futureintegrated circuit integration package to reserve space.

④ sapphire substrate transition method. InGaN chip according to the traditional manufacturing method in the PN junction grown on sapphire, the sapphire substrate removal, where can i buy led bulbs? and then connect on the traditional materials, manufacturing the upper and lower electrode structure of the large size blue LED chip.

⑤ AlGaInN the silicon carbide (SiC) on the back light method.  PN-type electrode at the bottom and top of the chip, using a single wire bonding, good compatibility, easy to use, it would become AlGaInN LED another mainstream products.

where to buy led candles by energy saving?

With the 1878 incandescent lamp into the Paris World Expo, the human bid farewell to the dark into the lamp era. 100 years later, the LED would be new Lightings.

Since last year, 100 watts incandescent lamps  are not allowed to sell any more, many cities have accelerated the pace of the street lamps into LED lights. Estimated that in 2023, along with increasing the degree of policy support and changes in consumer attitudes, the LED will gradually into family. After all, in accordance with the incandescent phase-out plan, four years after the family with an incandescent lamp will lock-up.

where to buy led candles by energy saving?

Now,  we don’t have any standard for LED lights, good and bad market, high prices, will hinder the promotion of its market. Buy a 25-watt ordinary bulb hair or buy a family living room with 7-watt LED light up to 60, 7 watt LED street light brightness is equivalent to a 40-watt energy-saving lamps, and the life expectancy of 6-7 years consumers willing to pay more than 60 RMB to buy a lamp? If the ordinary people build can not afford energy-saving concept, the LED lights the high price will make plans to ban 15 after 1 October 2016 watts and above the general lighting incandescent plan faces enormous challenges.
The key is the ability to reduce the net worth.

Herald reporters found that the family of a LED companies have introduced more than 60 RMB with the price of LED lights 4 watts, 30 watts sold more than 900 yuan, 45 watts up to 1200 RMB. Although LED lights can be used more than a decade, but most people rarely consider the long-term investments can not accept such a high price, and half prefer to change the light bulb of an 8 cents.” The LED company’s sales staff told the Herald reporter.

In fact, in addition to price, LED lights difficult to enter the ordinary people family is an important reason. this has led to low prices, uneven quality of products flooding the market.

LED industry blowout in addition to causing confusion in the market, overcapacity is also apparent. “Previously, the number of LED enterprises in the export trade, but with the debt crisis in Europe continues to linger, Europe and the United States and other countries reduce subsidies on energy-saving products, the intensity of the lack of external demand, shrinking export markets, resulting in excess of the domestic market.” Above Ms. Lee said, Some LED business has been difficult, and the retail market, consumers do not agree, do no funding support for municipal works, leading some LED enterprises have to rely on contract energy management company to survive.

 

where to buy led christmas lights, new LED Lights

Recently, the mainstream 0.5W and 1W LED Lights of price drops faster than the 5-10% decline in fourth quarter of 2011 and 2011 full-year decline of nearly 40% to 50%. It’s expected that in 2012 this rate will slow down, it is estimated that the 2012 full year it prices will fall 20-30%. where to buy led christmas lights?

To furtherly reduce the cost of the LED Street Light, some vendors try to use the cheaper silicon and metal materials as the substrate material to develop high-power LED, but this practice in the early 2011’s when a good subject, but last year the third and fourth quarter, as demand for LED production capacity and the sapphire substrate manufacturing capacity expansion, the end of last year the price of sapphire compared with the beginning of last year has been reduced by more than half. For example, the beginning of last year’s Sapphire’s price is more than 30 dollars, but by the end of last year, the lowest offer only about $ 7. When the sapphire prices fell to below $ 10, the substrate with other materials is not obvious advantages. where to buy led christmas lights?

Silicon substrate technology is actually developed quite early, but has not been developed, mainly because there are several important issues: First, the silicon defects, its luminous efficiency is relatively poor. The epitaxial growth of silicon, silicon itself will absorb light and therefore must silicon removed, do light carrier of other substrates (whether metal or other substrate). Here have to do the conversion of a substrate, the process itself is not so easy. When you increase a process when the silicon substrate to be replaced by another substrate, basically use the benefits of silicon. where to buy led christmas lights?

LED Products costs with silicon carbide substrate cost is much higher than the sapphire substrate, luminous efficiency of the silicon carbide substrate and the epitaxial growth of quality is better. The sub-opaque and opaque two types of silicon carbide materials, such as opaque silicon carbide substrate cost, rather than the transmittance of silicon carbide with silicon material, must be done after the epitaxial substrate conversion , the substrate conversion process will be related to another process, yields that there are some problems. So we mainly sapphire based materials, the technology has developed quite long and very mature.

where to buy led grow lights after Incandescent delisting

It’s almost in May 2012, after less than six months time, the incandescent lamp will start to roll over and die. Who would take the market share of 1.3 billion incandescent lamp? Fluorescent lamps? LED lights? where to buy led grow lights?

where to buy led grow lights after Incandescent delisting

LED lighting is available soon, with many of the advantages of energy saving, environmental protection, long life compared with fluorescent, then the LED lamps will replace incandescent market share? This is not necessarily, LED lights, this lighting revolution will be a long-term and arduous process. where to buy led grow lights?

Throughout the lighting market now, due to the large tracts of excellent prospects for LED lighting, the influx of many manufacturers, LED lighting internal “fight” have already begun,  making consumers’ confidence in the LED lighting products greatly reduced, in fact, a careful analysis on the capacity of the current capacity and the entire lighting market, the real level of competition in the market should be reflected in the LED lighting and fluorescent lamp.

Incandescent exit the stage, LED lighting products, the main rival is not the product competition between the manufacturers and the manufacturers, but competition between the traditional fluorescent lamps. Let’s imagine fluorescent roll in the market for so many years,  could easily be replaced by LED lights? At this stage, the boss of the concept of the surname is quite traditiona. LED can only control the cost of LED lighting products close to the fluorescent product prices, inorder to make LED lighting more competitive, more dominant struggle is fluorescent. where to buy led grow lights?

So, now incandescent is outgoing, who is still the biggest winner or an unknown, but theLED light is active, while the fluorescent lamp is passive. As long as the LED lighting industry standards, norms of good product quality, and establish consumer confidence inthe LED lamps. Plus as far as possible to reduce product costs, the prices are more readily accepted by consumers, such a result, I believe LED lighting will be victorious inthe revolution.

The rapid improvement of the efficiency of solar energy LED lighting is not only the seeds, but grace also

The rapid improvement of the efficiency of solar energy led lighting and led street light is not only the seeds but also grace

US government regulate to ban 100W incandescent compact fluorescent lamps in 2012. But people want to know that the only reasons for using compact fluorescent. Consumers do not completely change.

In fact, because of all kinds of reasons, a large percentage of consumers have rejected the compact fluorescent lamps, these reasons include flashing lights, color rendering, reliability and cost comparison, the slow start. The small fluorescent light on these issues have been resolved, but in the eyes of many consumers , small fluorescent light is not they wanted. The short term, if  used 100W incandescent lamps are burned, many of these consumers will switch to the halogen incandescent lamp.

This will pose a problem: solar energy led lighting can enter the neutral and the consumer will choose the options? So far, there is no commercially available LED lamps to replace the 100W A19 incandescent. The reason is that the passive cooling 1500lm(100W typical lighting the lamp output) LED is still not on the output in the physical level.

The white LED is a very efficient light source, about one-third of the input power is converted to light, the remaining two-thirds of the power is converted to LED in the heat. So 100lm / W, or about 100W power must be continuous and quickly consumed. If the heat has not been removed, the LED lamp will quickly heat up to 120 ℃ of the maximum working temperature.

This problem may eventually be resolved through the LED luminous efficiency. Last year, the best of cool white LED obtained the lighting efficiency of 100lm / W. This year, a lots of white solar energy led lighting get the efficiency of 120 ~ 130lm / W range. This trend in the foreseeable future will not be decayed.

With the improvement of LED high bay conversion efficiency, the thermal management of improvement is about the square of the efficiency. Because the total power of LED power supply is decreased and the percentage of heat generated by the input power also reduce the number of the corresponding.

 

“the three stages of development” in global LED lighting applications

LED lighting spread into the main lighting as early as in developed countries. The market for LED lighting products have a recognization and acception. The environmental protection of the LED lamps, small size, high reliability features increasingly is prominent. Under the higher electricity bills, long life, LED lighting is rapidly becoming the new darling of the market. As the use of global led lighting, LED market development have several stages.

The practicality of LED lamps

On the basis of the previous stage, the market has been recognized and accepted. The environmental protection of the LED lamps, small size, high reliability features emerged. Thus developed a series of products, which will be completely different from the traditional light source applications. The lighting industry will be a more open space for development. Lighting source is no longer playing a role in lighting, yet it is changing bit by bit in making more appropriate for people working and living. The fight by the various manufacturers is to design application advantage.

An alternative acceptable for LED lamps

This phase is mainly indicated luminous efficiency(energy consumption). It reflect the characteristic of high lighting effect(energy saving) and long life. As the price was high, so at this stage, it is mostly used in the business and market. The customer has an acceptable process. At first, it is the habit and appearance to make them accept. Under the circumstances of complying with traditional light,  global led lighting reflects the energy saving, longevity and other features make the market easier to accept the relatively high prices. Especially in commercial situations. The fight by the various manufacturers is the quality and price advantage.

The intelligent control of LED lighting
With the development of internet and new technology, LED street light, as the semiconductor industry, will catch this tour high-speed train to play out its high controllability. LED, From home to office buildings, from the road into the tunnel, from the car to walk, will give mankind a higher level of service. LED lighting industry will also be doing product design, to provid total solutions to the course.

With the gradual development of LED lighting, on the public places and lighting engineering auxiliary, global led lighting gradually replaced some of the traditional light source products.

On Advantages and Disadvantages of high output led lighting

LED is the abbreviation of Light Emitting Diode and it is a soild state semiconductor devices, which can be converted directly into electricity for light. The heart of the high output led lighting is a semiconductor chip.

At present, LED street light fluorescent lamp is becoming more and more popular and of great importance. Why it is widely used among people? And what is the advantages and disadvantages compared with ordinary fluorescent lamp?

As to the advantages, I listed as follows:

First of all, It saves energy and it is for long life which is very good for environment protection. Second, the applicability of the high output led lighting is very good because of the small size of the single led which can be made into any shape. Third, the response time is not too long but short. Led is nanosecond level of response time but the ordinary lamp is the level of response time in ms (milliseconds) not like led tubes.

The last but not the least, it made great contributions to our environmental protection and it is easy for recycling because of its harmless mental. What is more, Led is colorful, luminous and of pure color, narrow spectral range. Through the RGB, three primary colors can blend into a colorful or white.

As everyone knows, every coin has two sides. High output led lighting also has its disadvantages. There is not doubt that it is more expensive than ordinary lamp and the light efficiency and the theoretical light efficiency generally does a big gap. Moreover , there is a big gap to do the actual life and theory of life(10W hour) in a same level and there are still a certain amount of heat.

We believe that with the improvement of the LED Lights, the disadvantages will be reduced and it will be commonly used in the world market, even the ordinary lamps will be replaced by high output led lighting.

We are waiting to see this moment approaching!

LED lighting industrial should not only be given light subsidies for downstream

LED lighting industrial has developed rapidly in this two years. LED lighting, LED screens and other projects appeared everywhere. Eneltec group is to do the research and development of LED products chips, which is the core aspects of the LED industry. Faced with such situation, eneltec has a little bit unhappy.

Others will feel very strange, Is the policy not to encourage the development to LED industry? Many local governments have a subsidy policy of the LED lighting industrial. If the industry developed well, a chip development market will develop fast. While Eneltec think that the present subsidy policy did not play a good role in guiding the development of core technology.

Currently, government subsidies are often directly to the downstream production enterprises. The status of Chinese LED street light industry development is that each manufacturer of its core products are imported. Originally domestic chips have price advantage, while if government to have subsidy to manufacturer, it offset the high cost of imported chips, and more subsidies for downstream companies less to buy our homemade chips. What’s more, in some places when government purchase, bonus points, which further reduces the possibility of manufacturers with domestic chip.

The chip is the core of the LED lighting industrial, only did the chips do well, there is hope. Or the bulk of profits are took away by the chip makers, while China just earn a processing fee. The reason is very simple. Otherwise, local Chinese even is difficult to earn a processing fee, because a lot of foreign LED chip manufacturers.  such as Cree companies have already begun development for the lighting terminal. Mainland manufacturers abroad will find that he is competition with their own suppliers, and the bulk of the profits should give it to suppliers. How can we compete with other people?

When an industry separate the middle and lower reaches, the downstream manufacturers will get more subsidies, and it is often not conducive to the development of the upstream business. Chinese subsidies should complement more to LED panel local core studying. Government should, throught the development of certification standards, to protect their core technology development.

Japan solar energy led lighting Standard Focuses on Safety and Performance and Aim at the Replacement of Traditional Lighting

Japan is the country in Aisa to gain the most significant result from the implement of solar energy led lighting. Especially after the 311 earthquake, with the increasing consciousness energy-saving, the proportion of bulb LED street light sales rocketed and is the first time to surpass incandescent bulbs in June 2011, to become the highest proportion of electric ball lighting on Japan market.

Beside energy-saving awareness-raising, the remarkable achievement of promoting LED lighting in Japan, is also credited to the related specifications on safety, performance and interchangeability, formulated by body corporate led by the power ball industry of Japan, which not only offers norms for manufacturers to follow but also enable consumers to buy peace of mind.

The current solar energy led lighting standards in Japan are classified into two categories, Japan Industrial Standard and the JEL Japanese electric ball industry specifications. Until July 2011, Japan has already developed 6 JIS LED lighting specifications, and one of them is about safety specifications and performance requirements of LED lighting module and bulb LED light but there is still no national standards on the LED road lighting currently, only local governments to formulate their own specifications requirements.

It was four LED lighting specifications that are developed by the electric ball industry in Japan, mainly to define the ways of LED lighting and LED Tubes marking, and the light mouths between LED lighting and traditional lighting, as well as system compatibility, etc. Unlike traditional lighting LED lighting in the weight, circuit, system requirements. If the compatibility specifications was not developed, it could easily lead to damage of the LED lights when in use, even heat, fire, and other danger.

Referring to international standard IEC, Japanese solar energy led lighting standards are developed to regular safety and color rendition, brightness, life under a variety of environments, to eliminate products whose safety and performance are below the standards, so as to replace traditional incandescent light bulbs and other lighting completely.

Development Trend of the LED lighting company in Europe in 2012

The mature the led lighting company in the European region, although it did not see a similar large-scale subsidy policy, but high tariffs, and the light of cultural differences, commercial lighting and outdoor architectural lighting situations, the application of the persistence of demand.  According to the relevant bodies “from 2011 to 2015 the European lighting market report, the traditional lighting manufacturers in Europe more than halogen lamps, fluorescent lamps as the primary light source, now is also actively developing LED lamps and  with local architects, designers and global dealers to establish a close relationship, following the lighting engineering project of the European region. It is expected 2012 European the led lighting company will grow to 3.01 billion U.S. dollars, an important market that is worth of developing.

Benefit from some European countries, the implementation of the ban of the beginning of high-wattage incandescent policy, the 2011 European LED lighting market has exceeded  $ 2.08 billion. Meanwhile, the full policy published in 2012 that EU ban on selling  incandescent light bulbs, the market growth rate is expected to be a sharp rise. LED inside estimated LED European lighting will reach $ 10 billion level.

Europe as a whole lighting market is relatively mature, and are willing to pay a higher amount of lighting products. LED street light market in Europe will continue rapid growth and to strive the military commander for the Asian and European and American firms. If it can gain orders in the European exhibition, and set up the supply chain visibility, the led lighting company will obtain a more stable lead in the future.

European lighting market has been also led the popular culture of the global lighting market. The Milan, Italy since 1977, the international lighting and building technology exhibition, has 30 years of history, which can be regarded as the world’s most symbolic lighting exhibition. However, Germany Frankfurt International Lighting Fair in Milan in turn exhibited lighting and building technology and equipment exhibition (Light + Building)since it first held in 1999, and is a hard to find. The show has quickly become one of the most influential international exhibitions. In addition, other areas in Europe will hold fix lighting fair every year, showing the importance to lighting industry.
