Problems for LED street light bulbs

At present, the commonly used color temperature for LED street light bulbs is around 5000K (Cool White). However, as for a road lighting system, a light color with 5000K will make pedestrians feel cold, and also reduce farsightedness ability of drives. Some experts even believe that street lights with a temperature higher than 4500K will increase the number of traffic accidents. The most suitable color temperature for LED street lights is around 3000K (Warm White or Yellow White).

 

Without these unnecessary cost for maintains, Chinese LED manufacturers would had more money for developing LED street lighting technology. How to get out of this wrong region, that all depends on what policy will be put in place.

 

However, even cool white LED street lights has been replaced by warm white LED street lights, problems still exist within LED street lighting business, due to the lack of an identified technique standard. LED lighting business has been developed nearly ten years in China, but still lack of unified technical standards in product specifications, including color temperature, working time, product dimensions, etc. Each manufacturer produces products in accordance with their own standards, leading to market confusion. Taking color temperature for instance, same LED street light bulbs with same color temperature (3000K) will have distinguished color if they from different manufacturers. Sometimes, this difference is obvious. Without any identical standard, it is impossible for products to be generally used. For example, a certain local government decided to use LED street lights from one manufacturer in a road-lighting project. After several years using, some of these lights are broken, they only can be replaced by the same products from the same manufacturer. In other words, lacking of an identified standard among LED manufacturers reduces the flexibility of LED products, at least making the update and replacement of them become more difficult.

 

Lighting rate is a rather important examining aspect of related department. According to Chinese present manufacturing technology, broken LED street light needs to be replaced entirely instead of partly. It is very bad for Chinese LED manufacturers. In order to reduce the fault rate, they have to raise their cost of production, as well as perform long-term maintains. And it is also a bottleneck which blocks the spread of LED street lighting business in overseas market. No one would like to use street lights can only be replaced entirely when they are broke down. Meanwhile, it blokes the development of LED manufacturers. Without these unnecessary cost for maintains, Chinese LED manufacturers would had more money for developing LED street lighting technology. How to get out of this wrong region, that all depends on what policy will be put in place.

How to improve the working life of LED street light bulbs

 

How to improve the working life of LED street light bulbs

 

Recent U.S. Energy Star is being drafted to discuss the standards of the LED street light bulbs, among the more controversial point is that life on the minimum requirements, the EPA may be consumer lamp life requirements down to a minimum of 10,000 hours from 25,000 hours, because 10,000 hours compared to three hours daily point count has more than nine years of life. The latest EPA’s standard is that you can nominal life, the minimum of 10,000 hours, of course, if the test results, you can also nominal 25,000 hours or more.

 

The use of 9 years is enough for general home applications, hotels, subway stations, such as places of lighting required for a long time, you can use long-life LED street light bulbs, which indicates that the EPA later no longer LED lamp life across the board, only the minimum life requirements, the lighting of different places you can demand for life lamps, reflecting differences in demand for domestic enterprises is really good, so that small businesses and large enterprises according to their own conditions, to reduce the cost of LED bulbs while different levels, but also to improve the quality of their products, accelerate product updates and promotion.

 

Deal with material shortages. High brightness LED high bay chips metal indium is based on. The earth’s crust in the content in rows in the 61th, strategic metals in the number two, the development and application of growing, not rich reserves of global growth, the price, the expected future will appear periodic shortages. If LED into the general illumination market, bring problem is abundant raw materials? At present, many foreign countries and institutions and enterprises have begun to explore new chip in material, our country should also pay attention to this problem, to deal with the possibility of future rising prices of raw materials, research and development of new LED material.

 

Price competition for led street light bulbs

 

Price competition for led street light bulbs

 

Governments planning, the era of the incandescent exit lighting industry in the next decade, governments around the world are actively promoting the energy efficient lighting products, energy-saving lamps and led street light bulbs will compete for the lighting products market. With the rapid development of LED industry, the production efficiency, chip luminous efficiency increased dramatically, LED lighting product prices will drop quickly.

 

DRAMeXchanger’s research department LEDinside latest led street light bulbs retail price survey shows that following the retail price of LED bulbs dropped sharply in December 2011, in January this year (2012), the overall average retail price of led high bay bulbs continued to decline steadily, replace 40-watt incandescent bulbs, the average international price of $ 19.6. South Korea, the most intense price competition in first-line lighting brands introduced to replace 40W incandescent bulbs products terminal price has been under the killing to below $ 10. Replace the traditional 60-watt LED bulb part of the international average retail price of $ 35.4, only South Korea, the emergence of low-priced below $ 20.

 

Commodity prices to replace the traditional 40-watt incandescent bulbs, the average decline of nearly 7 percent in January. South Korea remains the most competitive region, the average retail price of $ 10.4, down 13 percent, the minimum price of about $ 8.2. In addition, the Japan region only one percent of the decline did not continue the substantial decline of the previous quarter, mainly due to yen appreciation, therefore translated into U.S. dollars decreased, coupled with LED bulbs in Japan has decreased.

LED Street Light bulbs are better than Caesarean section

A Caesarean section, (also C-section, Caesarian section, Cesarean section, Caesar, etc.) is a surgical procedure in which one or more incisions are made through a mother’s abdomen (laparotomy) and uterus (hysterotomy) to deliver one or more babies, or, rarely, to remove a dead fetus. A late-term abortion using Caesarean section procedures is termed a hysterotomy abortion and is very rarely performed. The first modern Caesarean section was performed by German gynecologist Ferdinand Adolf Kehrer in 1881.

From the above, the natural production of these two modes of production and cesarean section has its own advantages and disadvantages. In general, the natural production of most of the mothers, the relatively safe and less harmful, but under some specific indications, some mothers are in need of cesarean production, and some mothers even in the natural delivery
after the pain has started only temporary to cesarean section.

From my angle, Caesarean sections should be used only for some problems of birth, we should not escape the normal birth by Caesarean sections for the reason that, having less pain. Also, Pain Caesarean sections are not good for babies.

Also, LED Street Light bulbs are much better. We use LED Street Light bulbs to replace the MH and HPS lamps, these HID lamps are normally used in a lot of street lights. These LED Street Light bulbs are really good design and very high lumen output, save a lot of energy and long lifespan. If you use LED Street Light bulbs, hope you would be brightened your ideas, make you feel LED streetlight are better than edison lamps.
