 A low-voltage power supply, low power consumption: Generally speaking, the working voltage of the LED energy-saving lamps from 2 to 3.6V operating current is 0.02 to 0.03A This means: the power consumption is no more than 0.1W;

(2) the small size: the LED energy-saving lamp is basically a led ceiling lights chip is encapsulated in epoxy;


Long life: the life of up to 100,000 hours in the proper current and voltage, almost no maintenance. In addition, LED energy saving lamps full epoxy encapsulated, it is stronger than light bulbs and fluorescent tubes, light body and no loose parts, difficult to damage;


(4) high-brightness, low-calorie: general lighting with incandescent and halogen cheaper, but the luminous efficiency is low, in vain power consumption due to the thermal effects of light; LED lamps as lighting lamps, not only high luminous efficiency, and the cold The light source generates almost no heat consumption;


5 Environmental protection: LED lamps are made by non-toxic materials, unlike fluorescent lamps containing mercury can cause pollution, but also can be recycled;


6.LED energy-saving lamp with flicker-free, strong applicability, high stability, short response time characteristics;


As the LED technology and product attributes differ materially from those with traditional lamps, so the existing general lighting safety standards is clearly not applicable.


-Young Technology Certification Center (EBO) special write this article to explain the safety testing of the LED lamps requirements (for example) to UL standards.


(A) security specifications of LED lamps:


As technology improves, the use of LED lighting has been the past few decades, a simple application in the light, lights and other, and gradually use the phone backlighting, interior lighting, brake lights, LCD TV, laptop computer backlight and other auxiliary lighting ; and in the last two years, became the main lighting system, the scope of application covers, outdoor, commercial, and home products, res pectively:

And implementation of low-carbon economic policies of our government in 2010 following the Copenhagen conference, unwavering in two sessions after the launch of the Eleventh Five-green lighting development plan, making the LED semiconductor lighting industry quickly became a courtesan of the lighting industry, lighting companies have sniffed out the power of energy-saving subsidies and market. However, the development of the semiconductor chip technology is still in the stage of development, high-tech equipment and high-end talent prohibitive for many small and medium enterprises, the Shanghai World Expo and Guangzhou Asian Games venues, the project became Philips, Osram, NVC, Op, Huayi garden led lights corporate "patent".

The lighting industry this year seems to be the "nouveau riche" around the city lighting have listed Shilihe, Beijing, Wuhan Han Dynasty to the glory of Chongqing, Nanchang, Lights and so on. It seems that the road of the brand lamps slowly fade over the years the formation of monopoly necrosis brand sales model and it was "blocked" you?

The general manager of the Arts lamp Master Cheng said, although currently the LED semi conductor lighting is extremely strong, however, 70 percent of China s LED lighting companies mostly placing him downstream. Brand lighting, most of the times of active research and development, and design of LED lighting. This also marks the lighting industry, the light source as a starting point through the application of new light to reach the lamp from the shape, are leading the trend to light. While lighting the city to provide consumers with a broader brand lamps, quality, price, selection, with the internet e-commerce, activation, and active in the consumption pattern of the lighting market. However, high consumption of middle and low lighting, so that consumers care about the lamp after-sales service system, Although many lighting the city is committed to a one-stop supplier, one-stop service, but the difference between the grade messy lighting brands, quality, incomplete, accessories far, many consumers are still difficult to see the consumer advantages of lighting the city.

Lighting within the expert analysis, with the subsidy policy of the national energy conservation, improvement of living standards of rural lighting market has been opened, the lighting monopoly has become the best business model in rural and urban areas. As the lighting design, the shape of personalized, lamps, installation, maintenance becomes a very professional and the lamp consumption is no longer limited to the price, more consumers to pay more attention to after-sales service. Store for its professional and systematic after-sales service system, high-, mid-range lighting consumers have more trust stores.

LED lamps across the lighting industry, natural or product quality, brand high bay lighting and the Renaissance, and after-sales service. From China s economic development situation, the future of lighting stores will long endure. Brand building, will be the biggest motivat ion of lighting business development. How to build a good brand which requires enterprises carefully crafted and rich corporate culture and the spirit of accumulation.

For example, collected high-intensity gas discharge lamp (High-intensitydischarge; the HID) and halogen lamps to achieve high brightness, high illumination, the general store for a long time lighting, most of the choice of fluorescent tube ( CompactFluorescentLamp; CFL) lamps, residential multi-use incandescent lamps, fluorescent lamps (CFL) or energy saving bulbs, incandescent lamp power consumption is highest, because the runtime a lot of energy into useless heat dissipation for the life of the lamp will thus appear that compared to other lamps more short.


From the specific application, the areas covered by the general lighting market is very broad, including architectural lighting, signs, landscape lighting, retail, lights, street lighting and residential lighting. In the general lighting market, commonly used light sources including incandescent, compact fluorescent lamps (CFL), linear fluorescent, high intensity gas discharge lamps (HID) and a novel high-brightness light-emitting diodes (High-BrightnessLED; HBLED) and so on.


To discuss the differences in energy-efficient, it is necessary to set out a systematic, scientific assessment method for existing lamps, As to the imp ortant metrics to measure lighting is the input power and lumens. Performance measured by lumens per watt, multi-adopted benchmarks as (energy efficiency, efficacy) assessment, such as lumens per watt (lm / W) to compare the differences in the lamp.


To view the different lighting options, you will find on the poor energy led light bulbs for home of incandescent lamps to 60W incandescent, incandescent energy correction rate is relatively low compare CFL fluorescent energy performance of the relative weakness of many, because the 60W incandescent light of energy efficiency of about 10lm / W, compared to CFL energy efficiency of fluorescent lamps can reach 50lm / W. In contrast, this contrast is the HID one 100WHID can have 80lm / W, a considerable in produce 8,000 lumens of brightness.

Just look at China s civil lighting, there is a value of about 40 billion yuan in the market. "This is the Bi Bo Ling, chief executive of Philips Lighting (China), data revealed in an interview with an attractive view him as the representative of the lighting companies, China s lighting market is bound to be a compete for the Promised Land .


Their confidence stems from the Chinese Government s attitude and garden led lights lighting products a strong advantage.


Energy-saving advantages of LED lighting products indicates that can not shake the industry leader: According to insiders, a 11-watt high-quality energy-saving lamps, for example, the figures prove that the absolute superiority of the product: such an energy-saving lamp at 6000 hours 60-watt incandescent lifetime, than having the same effect, less power consumption of 294 kwh, saving expenditure of more than 160 yuan.


In recent years the Chinese government is more and more resolute attitude to the implementation of the incandescent phase-out plans, energy saving lighting products including LED lighting, including the privilege of access to strong government support. In addition, the domestic large-scale con struction of public facilities have been launched to increase the number of the use of LED lighting products.


Opportunities for hiding behind the huge challenges


Chinese market this huge profit margins began to be domestic and international lighting giant quietly locked. However, to get involved in this market will also be high risk. high bay lighting product cost is extraordinarily high, has become all want to pre-empt stationed in the corporate R & D investment in key industries, many industry insiders said that 2010 will be an important test of the capital strength of LED lighting companies. Who should occupy the high ground, who will have the overwhelming majority of the market.

Chinese market this huge profit margins began to be domestic and flexible led strip lighting giant quietly locked. However, to get involved in this market will also be high risk. LED product cost is extraordinarily high, has become all want to pre-empt stationed in the corporate R & D investment in key industries, many industry insiders said that 2010 will be an important test of the capital strength of LED lighting companies. Who should occupy the high ground, who will have the overwhelming majority of the market.

In the wrong direction, go further away, is also casting haze of confusion. Quite a few lighting companies have invested a large amount of money and a R & D of LED products, but the road ahead, how many of these companies are not clear. The good news is that the recent Ministry of Industry announced the first batch of lighting products, national standards, pointing out the direction for the company s product development. Analysis of the industry in a whole new field lighting business at home and abroad turn launched a fierce rivalry, who wins there is no set number of opportunities and challenges This is a need the strength of the contest.
