International LED enterprises intend to build their factories in China

Since China’s accession into WTO, foreign investment transformed from exemplary joins into strategic development in many industries, including LED lighting industry.

 

Firstly, we need to comprehend the purposes of these international LED enterprises’ continuous establishing factories in Mainland. Obviously, cost will be the most essential reason. Because of the tremendous manpower advantage, China has always been the favorite in manufacturing industry all over the world. As a manufacturing, LED lights need much more manpower compared with other industries. Although the invention of automatic production line may reduce pressure to some degree, the entire production process still required a large amount of human label. Cheap Chinese labor kept these international LED enterprises low costs. Besides, foreign investors also took the complete and convenient transportation system into account. Another reason is the market advantage. There is no doubt that China will become the biggest market for LED lighting industry in the future. Building production base in Mainland can speed up the feedback between customers and manufacturers, which is really essential to establish the brand influence.

Since China’s accession into WTO, foreign investment transformed from exemplary joins into strategic development in many industries, including LED lighting industry.

Secondly, we need to analyze the merits and demerits of domestic and international LED tubes manufacturers. Generally, international LED enterprises are more powerful in research and development area. More than 80% LED chips came from foreign LED companies in spite that more than 80% LED lighting factories are in China. Obviously, foreign companies have advanced technology while our domestic companies only can provide label.

 

Once we figure these problems out, comprehensively understanding the not-really-complicated lines under the superficial phenomenon, we could easily come up with solutions. However, the premise is we know which way is right to follow.

 

Unboubtly, technology improvement is the primary step. In order to increase the international competitions, we should have our own LED chips. Fortunately, China’s top 5 LED enterprises have transmitted their attention on this part, starting their research and development in intelligent LED lighting products area and LED chips area. Our LED manufacturers also need to put a premium on management to improve products qualities. Surely we must clear that simply competing in low-quality application market will keep our competitiveness in low levels. As a matter of fact, most of our LED lighting products are much cheaper than foreign products, but still lacking of popularity in high-end markets. These are problems cannot be solved only relied on low prices.


The Climate Group called on countries to accelerate towards low carbon commercial led lighting

In the recently concluded United Nations Conference on Sustainable Development, the Climate Group released an independent global technical test results, LED lights can save up to 85% of energy. The trial also found that the pilot of urban residents prefer LED lighting and believe that its social and environmental benefits. CEO MarkKenber of the Climate Group, said: “This report clearly shows that LED technology has been with the conditions of a wide range of applications in various towns around the world, we call on governments to remove policy barriers and accelerate the transition to a low carbon commercial led lighting.

The Climate Group called on countries to accelerate towards low carbon commercial led lighting

This independent test of the LED lighting project for a period of two and a half years, 15 tests were carried out in 12 cities around the world in New York, London, Calcutta, Sydney and Hong Kong. The test conclusions by “light clean revolution” the rise of the LED road lighting and led street lights its significance for the city’s report was first released.

The report analyzes the status of the global lighting market, as well as the prospects for the development of LED technology. For those seeking to upgrade and for large-scale LED retrofit projects for financing policy makers and urban commercial led lighting managers, the reports provide a detailed reference.

The concept of “clean revolution” movement advocated by the Rio +20 summit as where part of the Philips report by The Climate Group join hands together to complete, which is to practice “clean revolution”-a relatively small cost savings in a relatively short time.

According to statistics, 19% of the electricity used for lighting, and 6 percent of global greenhouse gas emissions from the lighting. If you double improved efficiency of the global greenhouse, the influence is equal to reduce half of the energy and electricity and heat production of greenhouse gas emissions. The same with other energy-saving technologies, energy efficient lighting will promote global prosperity. Only in the United States, the field of lighting energy demand, which is equivalent to the generating capacity of 198 medium-sized power stations.

The Climate Groups and Philips called for the establishment and implementation of an international low-carbon commercial led lighting standards, and to ensure that the world has the opportunity to enjoy the energy-efficient outdoor lighting.

stealth led grow light reviews for solar use

With the development and progress of solar photovoltaic technology, solar cells as a new energy, first applied in the civilian aspects of the lighting, solar lighting products due to environmental protection and energy saving dual advantage. The solar LED lighting products is the next generation of green lighting products, and its main components, including solar photovoltaic cells (PV) and semiconductor lighting (LEDs). LED solar lights integrated solar photovoltaic and LED solid state lighting the advantages of solar LED lighting systems to achieve the perfect combination of a new generation of energy and a new light. However, in the design of solar lighting, involving light, solar battery systems, battery charge and discharge control of a number of factors, any part of a problem will result in product defects.

stealth led grow light reviews for solar use

A first look at solar lighting composed of:
The key lies in solar photovoltaic technology and LED lighting (stealth led grow light reviews) a perfect combination of both direct current, low voltage and can be matched. The combination of the two do not need the solar cells produce direct current into alternating current, thus greatly improving the efficiency of the entire lighting system. The same time, by means of network technology or the use of battery charge and discharge energy, to make it more obvious advantages.
1, solar panels
2, the charge and discharge controller
3, the battery
4, the load
5, shell lamps

Second, the design used must be noted: (LED lawn lamps  (stealth led grow light reviews) , for example)

LED characteristics close to the Zener diode, the work of change in voltage 0,1 V, operating current of may change 20mA or so. For security, under ordinary circumstances, using a series current limiting resistor, a great deal of energy loss is clearly not suitable for solar lawn lamp, and LED brightness changes with the operating voltage. The boost circuit is a good way, you can also use a simple constant current circuit, in short, must be automatic current limiting, otherwise will damage the LED lights.

2, the peak current of the general LED 50 100mA, reverse voltage of about 6V, careful not to exceed this limit, especially in the reverse polarity of solar battery or battery no-load, high peak voltage boost circuit is likely to exceed this limit, damage LED (stealth led grow light reviews) .

3, LED temperature characteristic is not good, the temperature rises 5 ° C decreased by 3% luminous flux, summer should pay attention to.

The operating voltage discrete, the same model, same batch of LED street lights operating voltage has some differences, and should not be used in parallel. Must be used in parallel, you should consider are flow.

 

stealth led grow lights and led drivers

LED digital tube display use the drive circuit to drive the digital tube segment, which shows what we want, therefore, according to the different ways on the drive LED digital tube can be divided into static and dynamic categories .

stealth led grow lights and led drivers

A, static display driver:
Static drive, also known as the DC drive. Static drive means to each tube for each segment of code consists of a microcontroller I / O ports to drive, or use, such as BCD code – decimal decoder decoding to drive. The advantages of the static drive is programmed, the display brightness, the drawback is that takes up I / O ports and more, such as driving the 5 digit tube (stealth led grow lights)  static display, 5 × 8 = 40 I / O port to drive, be aware that a 89S51 microcontroller available the I / O port 32. Must be increased so the practical application of the decode drive to drive, increasing the complexity of the hardware circuit.

B, dynamic display driver:
Digital dynamic display interface is one of the most widely used microcontroller, a display, dynamic driving the all digital tube  (stealth led grow lights)  8 shows the stroke “a, b, c, d, e, f, g, dp” with the same name connected together, the other to increase the bit strobe control circuit for each of the tube very COM-bit strobe controlled by a separate I / O lines, when the microcontroller output glyph code, all digital tube received the same font code, but what is the digital tube will display the shape, depending on the control of the microcontroller strobe bit COM terminal circuit, so we just need to display digital tube strobe control open, the bit on the show the glyph, there is no digital strobe tube will not light.

Through time-sharing in turn control the COM side of each LED digital tube, so that in turn controlled display various digital tube, which is dynamically driven. In the rotation display process, per bit digital tube light time of 2ms, the human visual persistence of the phenomenon and the light-emitting diode (stealth led grow lights) afterglow effect, despite the fact that you number the pipe is not lit, but as long as the sweep The aim of speed is fast enough to create the impression that a stable set of display data, there will be no light flashes, the effect of dynamic display and static display is the same, can save a lot of I / O port, and lower power consumption.

Constant current driver with constant current driver on the LED digital tube is mainly the following:

1, showing the effect:
LED tube is basically a current sensitive components, the dispersion of the forward voltage drop large, and also with the temperature, you need to make it a constant current in order to ensure digital pipe has good brightness uniformity, and can not be temperature and other factors. In addition, when the temperature changes when the driver chips also can automatically adjust the size of the output current in order to achieve the temperature compensation of the color balance.
2, security:
Even short-term current overload may also cause permanent damage to the LED lights, digital tube, constant current drive circuit to prevent current fault extensive damage.
In addition, the Commission adopted VLSI characteristics of cascading delay switch to prevent reverse voltage spike damage on the light-emitting diode. VLSI also has thermal protection which automatically shuts down when any one temperature exceeds a certain value, fault indication and can be seen in the control room.

street solar lighting in LED machine

The jetting, belongs to the new led lights technology, which uses a nozzle alternative to syringes, to solve many problems. Jetting nozzles needed to fill the bottom of the device above the dispensing need to reach their location below the top (street solar lighting). Jetting nozzles in the entire circuit board side along the x and y directions, without the need for vertical movement.

street solar lighting in LED machine

And dispensing syringe, the nozzle does not form a continuous bottom-filling glue flow, and replaced every second jet more than 200 points after accurate measurement of the gel-point. With the move of the nozzle level, the gel-point can be the formation of linear and pattern of a variety of needs, the solid line, dotted line and a variety of other different graphics. Each jet by precise control of a jet formed by the gel-point minimum diameter of up to 0.33mm, for coating plastic patch area into the precise control of occasions is very important.

 

Injection technology is the glue from the nozzle at a faster rate, rely on glue momentum to make glue out of the nozzle. Each jet  (street solar lighting) will spray out a certain amount of glue. Common injection frequency is 100 Hz to 200 Hz, but will soon reach 1000hz. , There are several different jet dispensing needle dispensing. When the glue from the nozzle, before the glue in contact with the substrate and the separation nozzle. Each of the gel-point injection into the substrate to form points, lines, and graphics. In the dispensing position during the move, the dispensing head is not the movement of the Z-axis direction, thus saving a considerable amount of time. Needle dispensing robot in the X, Y, Z axis movement, glue flow from the needle out of contact with the substrate, relying on gravity and the substrate surface tension glue isolated from the needles. After the completion of each dispensing, a movement along the Z axis, and then move to the next dispensing position.

The LED products market is also benefiting from the spray adhesive technology. Spray adhesive process can spray a wide range of optical materials including silicone, UV curable conductive adhesive of the phosphorus doped in the high-speed dispensing position and precise dispensing and plastic volume control. The accuracy of the spray adhesive can improve the yield of high-value high-power LED street lights devices. Applied to the white light  (street solar lighting) production, phosphor powder and mixed glue dispensing, its consistency is a good improvement.

street solar lights in LED lumen

Increasing LED lights brightness can be broadly divided into two types, one is to increase chip itself, the amount of light emitted; Another method is the effective use of the light generated by the chip, increasing the exposure of the light irradiation to the expected direction.

street solar lights in LED lumen

The former is trying to improve the luminous efficiency of the chip active layer, as well as to improve the chip shape to increase the external light extraction efficiency, or chip, large-scale use of high current density to increase the amount of light emitted; the latter is the use of light wave control technology, that is, the package resin to form a special optical structure, the chip produced by light irradiation to the expected direction. If the LED (street solar lights) screen brightness of less than the expected value, you can also try using the following methods to improve the brightness after use.

(1) Changing the flow through the LED current, general LED tube  (street solar lights)  to allow continuous current at 20 mA or so, in addition to the red LED saturation phenomenon, the other LED brightness is basically proportional to the current flowing through.

(2) the use of the human visual inert gray scale control pulse width modulation method to achieve, that is, cyclical changes in the optical pulse width (duty cycle), as long as this repeated cycle of light is short enough , the human eye do not feel light-emitting pixels in jitter. LED display to provide a pulse width modulation is more suitable for digital control, so in general the use of computer content, almost all of the LED control system is usually composed from three parts of the main control box, the scanning plate and the display and control device. The main control box from the computer’s graphics card to obtain a screen pixel colors and brightness information, and then re-allocated to a number of block scanning plate, each scanning the board responsible for controlling the LED screen on the number of rows (columns), and each row (column) on the LED display and control signal with the serial transmitted. There are two serial transmission of control signals: one is to scan the board centralized control of each pixel grayscale scanning plate from the control box of each line of pixel brightness value decomposition (Pulse Width Modulation) then the opening of the line LED signal  (street solar lights)  pulses (light does not shine to 0) to the corresponding LED on the line with serial transmission, control whether the light. Used in this way the device is less, the serial transmission of data in a repeating cycle of light, each pixel requires 16 pulses in 16 gray, 256 gray scale needs 256 pulses, the device operating frequency limit, generally only the LED lights screen to do the 16 gray.

DOE: LED lighting products will be the most environmental friendly in the world

From a recent report published by Department of Energy (DOE), LED lighting products will be the most environmental friendly in the world. The most significant difference between LED lamps and traditional filament lamps is the degree of the impact on the environment. This report classified lighting industries as 5 levels in terms of environmental contamination or environmental effect. Among all kinds of lighting products, LED lights have been listed in level 5. “It is the last product that will cause damages to our environment.”

DOE: LED lighting products will be the most environmental friendly in the world

In another article named “The Manufacture and Effect of LED”, the author compared three different lamps (Filament Lamps, Compact Fluorescent Lamps and LED Lamps) in aspect of service life, production process and operation conditions. This report did a comprehensive study for the effects impacted by these bulbs during their packages, transportations, works and recycles. This is also the first report that discussed LED lighting products officially. DOE always spent a lot of energy on environment protection, especially for air and water sources, to maintain the international competition of the United States. There is another important reason: to save loads of money for families and companies.

 

“Review of the Lifecycle Energy Consumption of Incandescent, Compact Fluorescent and LED Lamps” is a conclusion mentioned in DOE’s last report. In this report, DOE continued to use this conclusion and summarized more concrete and detailed estimation.

 

This report suggested that traditional Compact Fluorescent Lamps (CFLs) was much similar with LED lamps in the aspect of energy consumption. Both of them consumed less energy compare with Filament lamps in manufacture, transportation and operation. Due to the high efficiency, 15W CFLs are equivalent to 60W Filament lamps. This report conducted totally 15 tests. 14 of them showed that LED lighting products will be the most environmental friendly among these three types of lamps.

 

In particular, LED lamps have a poor performance in recycling part. The majority of LED lamps are made of aluminum alloy, which will exert a significant effect on the earth after scrap and bury. Even so, LED lamps are still more superior than Filament Lamps and CFLs. DOE gave out several solutions for this problem and decided to improved the production process of LED lighting products to improve this situation.

 


HELLA indicated that LED technology will become the design point to automobile lighting

As a global supplier of automobile lighting and electronic led street lights system, HELLA (German) indicated that LED technology will tremendously impact the vehicle lighting design in next few years. In the interview, Dr. Herbert Wambsganss, the Engineering Director of Internal Lighting Section of HELLA suggested that LED lighting will bring a new era to internal vehicle lighting system. Drivers will find significant changes within cabs, and this LED-related improvement will give them a brand new and comfortable feeling. And also can exalt the brand popularity.

 HELLA indicated that LED technology will become the design point to automobile lighting

“LED is the most advanced lighting technology currently, not only for us but also for our customers. LED lamps emit monochromatic rays, any potentially harmful or unwanted radiation, such as ultraviolet or infra-red light, can be eliminated. Without any flickers, this light is totally harmless to user’s eyes.”

 

Although lighting design is not a primary consideration for passenger cars or commercial cars, HELLA still put this item in the first line of their development agenda for next few years. Some senior managers believed that the usage of internal LED vehicle lighting applications will increase four times within next 5 years.

 

LED technology provided internal automobile designers with a new design concept: how to improve their value in use and users’ driving experience. Data reveal that internal vehicle lamps with different colors will bring passengers different feelings. In one project carried out by HELLA and University of Hamburg, color of internal vehicle lamps will exert different impacts on users’ feelings and comfort levels. Nowadays, every driver in German will spend around 4 hours on average on their daily driving, even more for taxi drivers and lorry drivers. Long-term driving can easily causing visual fatigue and even wore traffic accidents. Over the past decade, HELLA always stressed the importance of internal automobile lighting design. However, no matter how hard they tried, automobile manufacturers were still unable to remove the hazard caused by traditional lamps, such as ultraviolet rays and flickers. It was LED technology that brought them a new life. Now internal vehicle lighting designers can have better performances with the help of LED. Compare with traditional lamps, LED lights gave them much less restrictions.


led lighting fixture end markets caused great concern

As my understanding, the professional management of led lighting fixture manufacturing companies have more than several thousand, but on the terminal market, specializing in LED products and operation of businesses but a few. Apparently, LED store in the market has not yet formed. Recently, the message on the LED store and channel construction of the terminal has caused for concern. Store model as one of the many sales channels, in waged LED on the market, it highlights the unique and innovative and functional models, then the store path of the LED lighting business, whether this kind of model can go or not?

led lighting fixture end markets caused great concern

Piloting view of companies

Wang Yuhong in Qingshang: the existing product line can completely meet the store display and consumers one-stop shopping, and the current LED market dragons and fishes jumbled together, consumers can not identify, Qingshang as LED leading enterprises, through the promotion of stores to establish a brand image, guide consumers to buy good led lighting fixture. Of course, each LED enterprise should consider themselves to determine whether it is appropriate to build LED brand shop.

Oakley Qing said: LED lighting products, class and style richness is far from reach home lighting, lantern level, features and advantages of LED lighting products also makes its choice of channel model compared to the traditional lighting narrower. As far as the LED industry development, the store has become the most viable end-channel model.

The Shengan Guang electric Guan Rui Zhong said: I think the LED store is feasible in a form shape. Although at the end of the market, specializing in led lighting fixture who runs just few business, yet the LED store in the market is relatively rare. But compared to the overall trends, this is an opportunity. LED store is not only a product sales, but more focused on her brand influence and service capabilities. Of course, the rich and high-quality product line support the LED lights stores, which is the basic conditions. However, not all the LED stores can open exclusive shop. Opening stores are the expression of the strength of a business, not having the funds. The most critical issue is that whether the enterprise and business have the soft power or not?

 

 

 

 

The fourth chapter: LED lighting industry marketing innovation “four gold strategy”

To carry out public led lights marketing

For many famous brands, with public service activities to expand the brand, the sales amount has become effective way. National large-scale township promotional activities at the fair Town. The United States in the microwave to select the part of the township primary school to carry out the giveaways of microwave campus, accompanied by activities of “sending film to the countryside”, which spiritual and enrich rural residents and cultural life.  Similarly, since 2006, Sky-worth has launched a project called “SKYWORTH new rural theater project” , a total investment of 10000000 yuan, to 600 counties of countrywide 4000 townships, about 80000000 to 100000000 rural audience film. Sky-worth also has with the vat-ti and song of the four seasons at the led projects. Sky-worth held in new rural theater project about LED lighting industry at the same time, in various parts of the marketing and brand promotion of the combination, in promoting the brand in the process of promoting sales and marketing, in order to achieve a win-win situation.

The fourth chapter: LED lighting industry marketing innovation "four gold strategy"

Lighting industry public service marketing activity first is worthy of mentioning Opple, in 2007, Opple gain a very good reputation through the “CCTV Spring Festival”.

However, this public service activities is best to be able to fall to the ground which is like Mid-ea, Sky-worth, as the middle of the depth of consumers. Last year during the Beijing Olympics, OKES held the floor of the public welfare activities and complimentary LED lighting industry products to farmers and schools in some poor and remote areas. Consistently take the invisible channels of NVC that began to emerge to strengthen the promotion of the ground. NVC initiated this year, “light action” energy-saving lamps, which carried out large-scale public activities “bright line” support the educational undertakings of the mountain villages. This event not only expanded the NVC brand influence, but also benefit for the NVC to deepen the channel construction in third and fourth degree markets.

Almost simultaneously, Op charitable activities fall to the ground in Shandong Province to carry out a “the Yimeng bright line” activities and to help cataract patients back to health. In fact, we can see that these public service activities is a way for three or four markets and rural led street lights markets.
