led street lighting suppliers tell you the reason of broken LED

During our using of LED, sometimes we meet with some broken LED Lighting Products, why? It’s take a lesson from the Chief Engineer of  Eneltec, the top one of  led street lighting suppliers.

Normally, whenever we see the broken LED, we would say it’s “dead”. The reasons could be different. One is the Leakage current over limit, the other is Internal connection lead of the LED lights off, this problem would also influence the other LED’s working situation, the reason is the LED works in 1.8-3.2V, normally are linked in series or parallel, so this problem is much more serious than the first one. So, let’s analyze the reasons for these “dead LEDs”.

led street lighting suppliers tell you the reason of broken LED

1. Static electricity would damage the LED Chips. As we all know, the ESD of humen being’s body could be 3000V, strong enough to break the LED chips. So the ESD protection is very important in the production line. Normally,  Grounding resistance should be 4Ω, some places’ request would be lower than 2Ω, every led street lighting suppliers know about this, but how to reach that?

Some low quality LED factories never test the Grounding resistance, others test them once per year, or once per season. As far as I know, the best led street lighting suppliers — Eneltec do these testing every month.

Sometimes, even in the lighting fairs, some LEDs “dead”,  the reason is because after some time of use,  the leakage current would be increased and also the problems of humidity.

There so may reasons of broken led lamps, the most important thing is that, we shall choose the good products from good suppliers.

Technology and market to accelerate cutting price down of the the led light

In recent years, China’s LED industry is developing rapidly and broad prospects. But to achieve the massive popularity of LED lighting, the price is the key. However, with thestimulation of technological development and market demand, this situation has begun to reverse. Past the LED an annual average price (ASP), a drop of the led light about 20-25% in 2011, half the decline in LED lighting is achieved in the past the annual decline instandards. According to the forecast, has been hampered by the price of LED lighting products to enter the general lighting field, is expected to be resolved within the next five years.
Career Company Products Sales Manager PaulScheidt Cree recently the progress made in the production of LEDs means that the LED bulb price closer to $ 10. Some experts have analyzed, as the technology matures in 3-5 years, the cost of LED lighting will continue to lower, reaching the average consumer  can accept “civilian price”, that is, the price of the ordinary household LED lights dropped as long as 40-60 yuan, the realpopularity in the domestic field.

At the same time, countries will phase out the incandescent lamp has been listed on the agenda, the incandescent lamp of the led light have been eliminated in Europe, energy-saving policyof the United States in 2012 to prohibit the use of 100-watt light bulb. In August 2011, the National Development and Reform Commission announced on its website “China to phase out incandescent road map (draft)”. In accordance with the draft, our country will be five years from October 1 this year, the led light, the phasing out of the field of general lighting incandescent bulbs. Alternative light source as an ideal interior lighting, which is undoubtedly to the LED has created a huge market space. The manufacturer of LED lights will also receive a great share of the total $ 40 billion global lighting market.

Recessed led downlights are important territory for the future of LED

Relative outdoor road lighting needs to face the test with the challenges of many of nature, the LED used in indoor and better stability, reliability, degree of difficulty isgreatly reduced, the pace of recessed led downlights development will be faster; more space for development of LED indoor lightingmore suitable for the characteristics of the product itself.Characteristics of LED products, the most suitable place is the interior lighting. “A lot ofpeople in the industry have said. Held on June 16th Guangzhou International Lighting Fair, more than 90% of the products displayed by the three major global lighting giant Philips, GE and Osram are indoor LED lighting products, which shows that theseinternational giants recessed led downlights confidence in the market.

Recessed led downlights are important territory for the future of LED

With decreasing costs, advances in technology, product maturity, the LED is expectedin about three years time, large-scale enter the field of indoor general lighting; with the LED lighting market share steadily increased, the scale will reach within the next three years 5% of the indoor lighting market; LED luminous efficiency is improving steadily, the current light-emitting efficiency of 120lm / W LED street light source can replace the traditional energy-saving lamp tube. Few years, LED interior lighting market is boundwith the LED light source luminous efficiency to further enhance the expansion of itsluminous efficiency more than 150lm / W LED lighting products to meet the vast majority of indoor lighting environment. Will reach 80% market share in recessed led downlights 2020, LED interior lighting, or a huge design space and because of the LED high bay, in addition to expanding thesize of the lighting market, but also will drive the development of related industries,markets, prompting the entire lighting industry, the big change .

The prospect of spotlight led flashlight is increasingly bright

As the core technology, equipment subject to the foreign manufacturers, the Chinese LED street light industry chain development will be restricted. Technology, personnel, patents, foreign upstream manufacturers to ferret out the three moat. To cross the divide, requires the accumulation of technology, a lot of time and money invested in spotlight led flashlight, more national policy support.

The prospect of spotlight led flashlight is increasingly bright

From a technical principle, the LED light technology is the mainstream technology of the future light source. At present, the LED Lighting mainstream technology has been mature and industrialization, quality rising, the unit product prices continued to fall, is a big trend. Thus, governments have been actively introduced the policy to support the development of this industry. LED high bay Japan, MITI in 1998 introduced the first of the 21st century project through financial subsidies, tax incentives and loan concessions policy, the global leader in stimulating the development of LED lighting technology. The U.S. government launched the next generation of lighting plan in 2005, government funding to support R & D and to establish industry standards, and the spotlight led flashlight industry, the implementation of tax incentives.
Since 2006, state and local governments have also introduced the policy, financial funds and subsidies to encourage the use of energy efficient lighting products.
However, these seemingly enthusiastic policy implementation various Guaixiang. LED public lighting Guaixiang one who invest LED who get the orders of the local, the local government investment and LED Highways application investment to an LED manufacturer to build the industrial park, industrial spotlight led flashlight circle, all local Highways works use of its products. And some of the manufacturers to get the order has not yet formed the production capacity can only be purchased product installation, there is no guarantee of the quality of their products, resulting in some cities, LED lights, the bright half dark half; manufacturer itself is also no real technology, production capacity.

LED street light companies are difficult

It is said that every penny earned by the street light manufacturing enterprises in China with the smell of blood. Although this is, indeed, a bit exaggerated, but after careful thought, felt this to put unreasonable.

According to the survey, China is currently about street light manufacturing enterprises 1200, the main production base in the Gaoyou the Zhejiang liangnong, the ancient town of Guangdong Dongguan, led street light company Guangdong, Sichuan, Chengdu and other places, the industry’s annual sales of approximately $ 600 million, the sale of street lamps channels belonging to the Government more than 95% of LED lighting Products engineering, industry mode of production orders for production of the very few companies do a lot of inventory, the street lamps profits from the sale of 8-25%. Lamp industry, the actual production capacity at the end of 2009 more than 200 billion yuan. Obviously, this is a serious excess capacity and labor-intensive industry.

LED street light companies are difficult

We found in the survey, the lamp industry is a highly irregular and industry. Mainly in the following aspects: First, non-standard business and employment. Staff health and social welfare are not duly protected, most practitioners have varying degrees of suffering from occupational diseases and lack of effective medical treatment, the disease is sprayed with the pole, galvanized, pole sanding, etc. caused by; Second, serious commercial bribery. Rebate for general government projects 25-45% of the cost of engineering, business owners reflect, led street light company  almost 99 percent of the government tender projects are the “human order, the so-called open tender in order to cover the eyes and ears of the world, just a show; enterprise serious tax evasion. Order to obtain orders, manufacturers tend to reduce the cost of a sword stabbing “tax” truly meet the national requirements of the corporate tax almost can not find a few; four companies to expense of the environment to survive. This is also the local governments to obtain more GDP of the enterprise to make the results of the concessions in LED high bay industry.

LED Street Lighting lamps enterprises in labor, led street light company  product sales, tax, environmental protection, according to law, then, the cost will have increased by 25-35% based on the original. In other words, the street enterprises in China is not business real legitimate profits earned their so-called profits to harm the health of employees, the deduction of employee benefits, in violation of the laws and regulations, and expense of the environment such as the cost in return. The source of this wealth is undoubtedly guilty, led street light company and it is bloody.
