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?

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!
