With the continuous progress of society, more and more household items and electrical appliances are developing towards an intelligent direction, using the much humanized operation design. It is no doubt that smart phones are the most outstanding one, yielding too much surprises and happiness. As a part of emerging industry, LED lighting also applied a variety of intelligent designs, especially in LED street lamps, LED Tunnel Lights and high-power LED power suppliers.

 

With the continuous progress of society, more and more household items and electrical appliances are developing towards an intelligent direction, using the much humanized operation design.

 

Intelligent LED Street Lighting System utilized centralized monitoring and control, dimming LED street lamps conditionally according to specific using requirements. It is proved that the average energy-saving level of the entire system is around 20% to 30%, and the average service life of lamps can be extended by around 10%. Preset information will be embedded into CU in advanced. Once failed in some branches, the central controller can detect breakdowns immediately and give prompt responds.

 

Intelligent LED Street Lighting System used on bridges used TCI/IP protocol. After optimized signal transmission, more lamps can be connected into LED lighting system and consequently extend applying distance. The transmission control protocol can increase the reliability of Intelligent LED Street Lighting System. In next sections, we will list several main functions of this system:

 

1)       100 levels for brightness adjustments and 16 levels for gray-scale loss of brightness adjustment.

2)       Frequency can reach up to 85Hz.

3)       256 RGB color adjustment capacities.

4)       Brightness depth can reach up to 1024.

5)       Every individual controller can automatically sample input signal.

6)       Support user-configure.

7)       Power supplier: 24VDC/110-220VAC.

8)       Support remote control and serial communication.

 

Synchronous operations can be realized by this system, no asynchronism, approximately zero power supply errors. The average luminous flux should be maintained on a level of 100lx. The stimulating system is not base on surrounding brightness rather than time. External optical sensors detect surrounding light intensity at a frequency of 10/mins. Once the value fall below a certain value (brightness threshold), the central controller will send out a “switch on” signal to each individual triggers. It is cleared that this intelligent lighting system can automatically adjust “switching time”, also can be successfully turned on in rainy and fog days. LED lights manufacturers began to add solar energy technology into this system, making it more environmental friendly.

What kind of LED lighting products does African market need?

What kind of products does African led lights market need? This is the primary problem faced by the lighting companies who wish to enter the African market. The African market is the low-end applications in the lighting market, but low-end does not equal low-cost. Lighting products companies in China exist deviation in the product positioning. Mainly in the blind pursuit of high brightness, power is not conducive to lower costs. China’s product itself has a cost advantage. Wang Guohua pointed out that the African led down light market is not very high requirements in terms of product performance, lower cost, with basic lighting functions, reliability and durability to ensure that the product of three years without replacement, simple operation to meet the market demand.”

What kind of LED lighting products does African market need?

At present, 1.7 billion people in worldwide living in the dark. In Africa alone, there are 500 million people who live without electricity. For an inspection who tour the lighting conditions of the African market. This is absolutely not just a bunch of numbers, their personal life feel the desire for bright people in Africa. “About 90 percent of the rural population in Africa has no electricity supply. The small streets of many cities basically have no street lights, one evening, the small vendors in the market will lose the hustle and bustle during the day.” Basic lighting and municipal lighting market is the most potential market in Africa and it is in urgent need of development.  However, the off-grid solar lighting products are the most suitable one. the indoor small portable lights, a 5-watt solar LED bulbs, emergency lights, etc can meet the basic lighting needs, and which are the promoting product in the near future. It it noteworthy that the differences of the existing street lights of the African market and China’s domestic development, many parts of Africa market and China’s domestic development. Many parts of Africa is directly tried to telephone poles, and in order to prevent damage to the shell on some street lights and also wrapped around a circle barbed wire.  Looking from the installation form, the optical configuration can not achieve the lighting effect, which requires enterprise to think about how to integrate our existing technology, and combine with local LED lighting products and installation conditions.”

 

 

More than 90% domestic LED producers need loan

On 24th July, a Fund and Industry Strategy Symposium was held in Shenzheng by Shenzheng LED Industry Federation and the Minsheng Bank. 32 LED lights manufacturers attended this Symposium, more than 90% of which expressed their willingness to obtain loan. And about 80% will spend this money on development their chip technology, only 20% indicated that they would like to this money for other purposes. And more than 70% domestic LED producers intended to apply for a loan of more than 250 million yuan.

 

On 24th July, a Fund and Industry Strategy Symposium was held in Shenzheng by Shenzheng LED Industry Federation and the Minsheng Bank.

 

Cao Yon, Minister of the Financial Services introduced that among 600 members (most of them are LED lighting producers), 39 enrolled in the meeting but only 32 took part in. According to the size of this Symposium, there should be more than 50 companies plan to establish the fund, with a total amount of 10 million yuan. That means each company should put at least 200 thousands into this fund pool. In 20 pieces valid questionnaires, more than 90% LED tubes enterprises applied for loan. One of them indicated that the amount of mutual fund loans is much higher than that of small loan companies. Besides, the 10% annual interest rate is also much lower than 30% of small loan companies. “We need a lot of money, but lack of confidence to go to banks. Mutual fund can really do us a favor in this part.”

 

Meanwhile, Minsheng Bank indicated that they will limit the large amount loans with a certain percentage of control. Loans larger than2.5 million yuan should be under rigid restrictions. 7 of these 32 domestic LED producers have met the requirements of large amount requirements and expressed their desire to apply for loans larger than 2.5 million yuan. There is limited cash available and many businesses asking, the organizer acknowledged. Loan ratio can be adjusted according to the overall participating situation of fund companies. For example, if more giant jointed into, the ratio of large amount loans will be increase as well.

 

Among all these enterprises, about 45% plan to use this money to alleviate the working capital pressures; 20% of them for restructuring; and 80% will spend this money on technology research and development; 55% indicated that they are planning to expand the production scale.

Technical data of high-power LED street light

With the development of LED lighting technology, the average lighting efficiency of high-power LED street lights can reach up to 80lm/W, making the application of LED street lighting possible in most countries. LED lights, especially high-power LED street lights are impacting the traditional street lighting market at a rapid pace.

 

With the development of LED lighting technology, the average lighting efficiency of high-power LED street lights can reach up to 80lm/W, making the application of LED street lighting possible in most countries.

 

LED street lamps with power consumption more than 30W can be defined as high-power LED street lamps. The current street lighting standard is uniformity of road surface illuminance. The basic requirement of LED lighting products is 0.48 of this value. And the spot ratio should be 1:2. (1/2 center spot should reach up a lumen output of 25lux, and 15lux for 1/4 center spot, at least 4lux for spot 16 meters far away from center spot).
