Second Chapter: Several major development trends in the led lighting industry of network marketing

Low-carbon energy-saving lamps, green led lights marketing

Low-carbon economy has become the development direction of all walks of life. The lighting industry, of course popular energy-saving light source, led lighting industry become the new darling of the lighting industry. Shanghai World Expo. Guangzhou Asian Games major venues in the lighting system, highlights the rapid development of the lighting industry. Europe, America, Japan and South Korea launched by countries of  out of incandescent, energy saving lamps, LED lamps, the popularity of programs are being implemented. China is also developing new light in the street lights and interior lighting. The green lighting is changing people’s concept of lighting. “Two sessions” further clarified the low-carbon, the implementation of the national low-carbon subsidies, home lighting industry has ushered in new opportunies for development. Internet marketing also draw support from the green marking trend, in order to play a greater advantage.

Second Chapter: Several major development trends in the led lighting industry of network marketing

Knowledge of marketing, let me tell you quietly

In a network environment, the nature of the market has undergone profound changes, manufacturers and consumers can chat directly through the network for information exchange, commodities trading. The marketing will become more diversified, personalized and though market segmentation. And the consumer’s behavior also have some changes. Consumers will be more extensively involved in the marketing process. Consumer behavior will become more rational, individualized. Liu Dongming Internet marketing mentioned that the led lighting industry is still relatively scarce industry. The public are lacking of LED knowledge, which is a good opportunity for LED industry marketing. In the name of the company to publish LED literacy, timely and properly respond to customer issues, and receive customer e-mail and customer make the right reply, enhance customer understanding of lighting products are to enhance customer retention and brand awareness in order to motivate an effective means of consumption.

Communication to be good by social media

The communication method between Lighting businesses and consumers are very different. The traditional  marketing model may only need a customer service hot line, site service can be carried out through the service network. But the network marketing companies need to understand three points: First,  how the consumers know your brand and products, second, how to let them to buy your products, third, how to make the consumer for the dissemination of positive information. These need to constantly sum up and continue moving forward.

 

 

specifications of led and led street light

In recent years,  a lot of suppliers in Taiwan and the mainland China are planning also a lot of LED demonstration road works case, for the LED lights industry into the power of technology to continue to grow.

specifications of led and led street light

2008 LED street lights 45Lm / W luminous efficiency, and progress to the end of 2009 the factory is now published 80Lm / W luminous efficiency of the lighting standards Regardless of 80lm / W luminous efficiency product quality, whether it can be notice by the end of 2008 the CNS15233 the standard specifications, but also because of the timely support of the Governments of expanding domestic demand, the luminous efficiency of LED lamp products in advanced from all walks of life, fought to enter the LED street light industry, which makes the R & D capabilities, significant progress, I believe in In the near future, the luminous efficiency of LED street lights can progress to completely replace the traditional form of the existing high pressure sodium street light.

All LED lamp products in the design of cooling the processor, generally can be summarized in the aluminum extrusion heat processor, fin-type heat processor and the heat pipe combination of heat processor, in which the aluminum heat processors are mostly processor exposed lighting appearance, this approach has the advantage in the cost of cooling the processor can be relatively cheap, especially mold development costs more competitive, but during the product development of high-wattage, weight is a must pay attention to factors, because the public regulation of the poles on the tolerance of the stress there will be certain restrictions, but also in the high-wattage products generally are using fin type radiator, or the way of the application of heat pipe design thermal treatment plant.

In addition to the heat processor R & D LED lamp structure is another important role is the power supply, because the prevailing LED products for a DC-driven light, and therefore on the manufacturers of the power supply must be customized based the development of a dedicated power supply for various styles of LED lamp products, but also have differences in accordance with national product safety norms for the adjustment of the circuit, to comply with the specification of the safety of the product re-sold throughout the world. We have the experience of the three places the case of LED street lamp project in recent years, LED lights dead lights phenomenon accounted for most of the ratio are caused by the instability of the power supply, power supply stability, will also affect the LED lights on the outdoor use, is it possible to maintain good light decay control within three years.

Secondly, the LED lights in the product development important technical threshold capacity of optical design, good lighting with light features, allows the LED street light evenly distributed in the way of the illuminated surface, Taiwan’s the NS15233 standard specification, only for street lights in a vertical 80-degree angle and 90 degree angle should be less than 30 and 10 of the glare quality requirements. On level 65 ~ 95 degree angle is greater than the specific brightness limit, the rest of the lighting technology, optical design capacity of each product, because some of the engineering case will require the road surface illuminance level limit, then a good optical design can make the light efficiency is slightly worse LED lamp products, the actual level of illuminance of the road surface was good.

Conditions of quality and reliability problems, the LED street lamp Competition to see the rest of the soft lighting to show performance, existing LED lamp products, most of them have adopted the German company OSRAM for street products, bat wings wide-angle two to light distribution design, optical design, each vendor has its own know-how and do not necessarily accept, you can still continue to try to make the street lights road lighting more to improve the efficiency.

1 Introduction

With the rising awareness of global environmental protection, energy saving has become the trend. The LED lights industry is one of the industries most attention in recent years. Now, LED products are energy saving, energy-saving, high efficiency, fast response time, long life cycle, and does not contain mercury, with environmental benefits and advantages. General, however, LED high power input power of approximately 20% can be converted into light, and the remaining 80% of electrical energy is converted into heat.

In general, the heat generated by LED light can not export, will make the LED junction surface temperature, thereby affecting the product life cycle, luminous efficiency, stability, and the LED junction surface temperature, luminous efficiency and life relationship, the following diagram for further instructions.

2, the LED thermal path

Depending on the packaging technology, the cooling method also is different from the LED variety of thermal path method can approximate Figure III indicate the:

In general, the LED grain (Die) to fight the golden thread, eutectic or flip chip way to link its substrate (Substrate of LED Die) and the formation of an LED chip (chip), then then the LED chip is fixed on the system circuit board (System circuit board). LED possible thermal path for heat directly from the air (shown in three ways 1), or by the LED die substrate to the system board to the atmospheric environment. Heat from the system board to the rate of the atmospheric environment depends on the entire LED lighting system design.

However, at this stage of the cooling of the entire system bottlenecks, mostly dominated in the heat conduction from the LED die to the substrate to the system board. Possible in this part of the cooling channels: one for direct by grains substrate cooling to the system board (Figure 3 ways 2), this thermal path, heat dissipation capability of the LED die and the substrate materials is quite important parameters. On the other hand, the LED generated by the heat will be through the electrode metal wire to the system board, in general, the use of gold thread to do the cooling by the metal wire electrode junction, more slender geometry limited (such as three way 3); Therefore, the eutectic (Eutectic) or flip chip (Flip chip) bonding recently, this design significantly reduce wire length, and a substantial increase in wire cross-sectional area, this way, by the LED electrode the cooling efficiency of the wires to the system board will effectively improve (Figure 3 way and 4 below).

Explained through the thermal path above, learned that the choice of the heat the substrate material and its LED die packages accounted for a very important part in the management of LED street lights heat dissipation, and back outline for LED heat dissipation substrate.

Do you believe, the color is actually a living: they have the Smart, can make all kinds of space, color affect our mood. However, in most people’s living space, pale or warm light, we are generally accustomed to. The new LED lights change color, that is, LED lamps with dimming, color mechanisms can produce the effect of altered space atmosphere.

spotlight led flashlight and RGB LED

LED lights change color by the capacitor step-down power supply, LED controller and G and R, B tricolor LED array. Its shape and milky white incandescent bulbs, but after the light change color automatically at a certain time interval. Back to the enclosure to issue green, yellow, green, purple, blue, red, white light. When the lights change color of the color was originally the three primary colors LED lights up two LEDs, which can issue a yellow, purple, blue (such as red, blue LED light issued by the purple light); if red, green and blue LED At the same time, when lit, it will produce white light. If the circuit can make the red, green, blue LED lights, a separate light and three-color LED is lit at the same time, issued in seven different colors of light. Outer bulb must be milky white. In order to better blending, non-transparent materials.

LED lights change color for the family birthday party, holiday parties, festive New Year to add a festive atmosphere to the festival: it can also be used for entertainment and advertising lamp, etc.. For example, blue light halo off the 6:00 in the morning, fresh and soft, warm yellow, cute pink, light green, applied to the comfortable scene. Romantic lilac people to think of wonderful memories, home or commercial space in accordance with need to match the color of the atmosphere, you do not need to change the interior decoration or lighting.

However, these lamps have a troublesome shortcomings is to control the color change of the circuit of the cost is high, the life of the drive circuit will be a problem, the industry, there are many kinds of solutions to cope with the expected in 2009 class of applications will be more and more, LED mood lighting market take-off of state in 2010.

The chief components of LED panel lights

LED lights diffusers:

LED diffuser is just a tin plate between LED LGP and the cover. It can evenly guild the light generated by LGP and evenly transmitted them to the cover. It also can be seen as a kind of shield for LGP, blocking or frosting the grid. Normally, diffusers use sheets of acrylic 2.0 or other materials like PC. Acrylic sheets have a higher luminousness but cost much less. In anti-aging aspect, PC materials have a better performance than acrylic sheets. Manufacturers for LED panel lights often take tradeoff between them, finding a suitable balance. Rich and powerful LED giants may even develop their owner LED diffusers, while small and medium sized companies still relies on other LED diffuser factories. After LED diffusers being mounted, most grids on LGP should be covered (totally unseen) and meanwhile designers still need to keep the luminousness as much as 90%. The luminousness of acrylic sheets is around 92%, while that of PC materials is around 88%. Manufacturers selected suitable diffusers materials depending on their specific needs. Currently, most LED manufacturers preferred acrylic sheets.

 LED diffuser is just a tin plate between LED LGP and the cover. It can evenly guild the light generated by LGP and evenly transmitted them to the cover.

Reflector:

Not all light can pass though LGPs and diffusers. Some of them will slip into the backside of LED panel lights. Reflectors can reflect more than 90% of backward light, which can dramatically increase the lighting efficiency.

 

Covers:

Covers for LED panel lights are usually made by aluminum alloy (1060) and also can be considered as part of cooling section. A good cover can effectively reduce the light attenuation and extend the service life of product.

 

LED derivers:

LED lighting products work under DC. They are pretty vulnerable to voltage fluctuations. Even tiny change in voltage may cause violent vibration to LED current. As we all know, LEDs need very rigid working environment – a constant current. High-frequency Derivers are typically developed for LED lighting products, using constant current power suppliers. This module has higher efficiency. PF can reach 0.95. Another module applies constant voltage/current power suppliers, which provide both constant voltage and constant current. This type of drivers have higher stabilities, but cost more than the former, and also have lower efficiency. Constant voltage/current power suppliers are mostly used in export products.

High-power LED Downlight in the early input costs to be higher than traditional lighting, but after prolonged use, the consumption of the total cost will be lower than traditional lamps. Therefore, using high-power LED Downlight in significantly superior to the traditional incandescent light. And because of the high-power LED constant current drive, no flicker, long working environment eye fatigue. High-power LED is characterized by:

1 less power consumption, high power LED: light efficiency 65Lm / W of LED is more than equal to the brightness of incandescent power consumption savings of 80%.

2 long life, high power LED: LED life up to 50000h, 24 hours of continuous light available to seven years.

3 high power LED response speed approaching nanoseconds, the dynamic of brightness and color easy to control, to achieve the dynamic change of the digital control of color.

4 high-power LED design: buildings can be a good match to achieve the effect I saw the light but not light.

5 high-power LED clean and green: no toxic metals mercury, infrared and ultraviolet radiation.

Color: different wavelengths produce different colored light, bright and saturated, no filter, the formation of red, green, and blue control is available in different colors, and can achieve the effect of full-color, gradient, and a variety of colors.

High-power LED to replace the incandescent light source showed the advantages of energy saving and long life incandescent and some other traditional light sources in many technical aspects of room for improvement is very small, the LED lamps to replace or replacement of existing lighting halogen bulbs in the downlights, light bulbs, gas discharge, incandescent light bulbs, luminous efficiency of LED downlights improve the efficiency of traditional lamps, but, due to the higher initial purchase cost, compared with fluorescent lamps, energy saving lamps, the energy saving effect is not very clear.

ssl led lighting and car led

The led lights lamp structure of the modern automobile is increasingly complex, increasingly sophisticated technology, the functions become more perfect. The heart of the automotive lamp light source, the evolution of the automotive lighting has gone through four stages, the fourth generation of the LED automotive light sources, and far-reaching impact on the change of car lighting.

The first generation of automotive light sources is the direct combustion of fuels (candles, kerosene or acetylene) light, it can meet the requirements of the early lights, but there are low luminous efficiency, light intensity, performance, instability, complexity of obvious shortcomings.

The second generation of automotive lighting is incandescent: 1879 Edison invented the incandescent lamp, 1913, the first incandescent lamp technology used in the Cadillac automobile headlamp, auto lamps have undergone a revolutionary change, from the automotive lighting into the electrical age. Then, has appeared in the car mirror, starter, generator and battery technology, the 1925 car is truly entered the era of incandescent automotive lamps. 1950s, halogen, it soon became the car strong light bulb such as led street lights.

The third-generation automotive lighting gas discharge lamps (HID): It has the advantages of high luminous efficiency, high brightness and high reliability, will replace incandescent, halogen and a new headlamp light.

The fourth generation of automotive lighting is LED: LED is a semiconductor PN junction diode, the PN junction when a forward bias imposed by the PN junction at both ends, are excited carrier by low-energy state transition to the high-energy state, when in the energy state of the instability of the carrier back to the low-energy state complex, according to the conservation of energy
Management, the excess energy will be the photon released in the form, it is LED electroluminescence principle. It is not warming through the heat can make objects glow, direct conversion from electricity to light, the energy difference of the emission wavelength depends on the carrier that is, the high-energy states and the difference between the low-energy state.

As for the interior light, more and more use of the LED, auxiliary lighting, LED interior lights, and dashboard LED backlight.

LED auto lamps before the basic structure consists of five parts: 1.LED array, two mirrors, 3. With light microscopy, 4 radiators, 5. Drive circuit.

LED car lamps directly associated with the development of the LED light source, only when the technology advances in LED lighting, LED light source applications in front of the car lights will be more popular. Future LED lamps with the LED to improve the quality, the price drop, LED light will break out again lighting revolution, a landmark, it will further affect the change of car lighting.

The inherent characteristics of the LED lights is the ideal light source to replace the traditional light source, LED is basically a tiny chip encapsulated in epoxy, so it is very small, very light. Low power consumption, under the appropriate current and voltage, LED service life of up to 100,000 hours. The LED is non-toxic materials, unlike fluorescent lamps containing mercury pollution caused by the LED can also be recycled. Since the LED is completely encapsulated in epoxy resin inside than light bulbs and fluorescent tubes are sturdy. Light body and no loose parts, these features make the LED can be said that is not easily damaged. LED as a new type of lighting technology and its application prospect is remarkable, especially in high-brightness LED known as the most valuable source of the 21st century, will cause a new revolution of lighting in the area.

1, user-friendly

Needless to say, the light of human relations is an eternal topic of the highest state of the lamps is the highest manifestation of the “shadowless” user-friendly lighting, no traces of any common lamp in the room, so that people can feel the light but can not find the light , embodies the perfect combination of light and of human life, humane design.

stealth grow led light and Humane and artistic

LED lighting product light, the choice of different light-colored LED into the soft illumination of the various modules, and any installed in the living room, bedroom lighting, the light source may be from the floor, wall, window sills, furniture, accessories and other. Therefore, the next room lighting will no longer be limited to a single lamp, but will be a single lighting into the shadowless lighting apparatus of the overall lighting effect. The different colors of light and brightness to produce different effects on human physiological and psychological can, in many cases do not need a very bright white light may be yellow or other colors of light more suitable for physiological and psychological needs. Three color LED tubes brightness, grayscale and color continuous transformation and selection, making the lighting extended to a variety of colors of light from the white light on the universal significance.

Therefore, it can be based on the overall lighting needs (such as color, temperature, brightness and direction, etc.) to set the lighting effects to achieve the control of human wisdom, and create a different interior lighting effect.

2, art

The light color is to constitute the basic elements of visual aesthetics is an important means to beautify the room. The selection of the light source is a direct impact on the artistic effect of the lighting, LED light color displayed on the display lamps art unparalleled advantages; color LED products cover the entire visible spectral range, and the color is good, high color purity, red, green select the yellow LED combination of color and grayscale (16.7 million colors) with greater flexibility. LED technology allows organic combination of scientific and artistic living room lamp, breaking the traditional lamp Collage frame, beyond the inherent concept of the so-called lamp shape, lighting design in the performance of visual perception and forms of artistic creativity, a new perspective to get to know, understand and express the theme of light. We can be more flexible use of optical technology in light and dark mix of light and color combination of materials, structural design advantages, improve the design freedom to weaken the function of the lamp lighting the lamps become a visual arts to create a comfortable and beautiful art of the light effect.

With the further maturity of the LED technology, LED will be fully embodies the development trend of the art lighting and humane, cultural dominant of the room lighting.

a dispensing type: on the printed circuit board through dispensing equipment in Sizing.
b Squeegee type: the printing of steel mesh or copper mesh coated scratch sizing.

3, Epoxy Method
SMA can be used syringe dispensing method, the needle transfer method or template printing method applied to the PCB. The use of needle transfer less than all of the application of 10%, it is the use of needles arranged in the array immersed in a plastic tray. And then hanging plastic drop transfer to the board as a whole. These systems require a lower viscosity of the adhesive, but also on the moisture absorption, good resistance, because of its exposure in the indoor environment. Control needle transfer Epoxy key factors including the temperature of the needle diameter and style, plastic, and the cycle length of the needle immersed in the depth and dispensing (including needle exposure to PCB before and during the delay time). Pool, tank temperature should be between 25 to 30 ° C, which controls the number and form of the plastic viscosity and gel point.

Template printing and led panel is widely used in solder paste can also be used with the allocation of glue. Although less than 2% of SMA using the template printing, but this method has been increased interest in new equipment is to overcome the earlier limitations. The template parameter is the key to achieve good results. For example, the contact printing (zero off-board height) may require a delay cycle, allows the formation of the gel-point. In addition, non-contact printing of polymer template (about 1 mm gap) requires the best squeegee speed and pressure. The thickness of the metal template for 0.15 ~ 2.00mm, should be slightly larger than the gap between the component and PCB (+0.05 mm).

The final temperature will affect the shape of viscosity and gel point, most modern dispensing machines rely on the needle mouth or chamber temperature control device to maintain temperature above room temperature of the plastic. However, if the PCB temperature increased from the preceding process, the outline of the gel-point may be damaged.

 

First Chapter: Several major development trends in the led lighting industry of network marketing

Lighting industry network marketing is lagging behind, and also in the led lights marketing tools. There are some companies or operators continue to try to do online sales. As for the present, the led lighting industry network marketing is still in the initial stage of “staking” there will be more enterprises to participate in future prospects. What are the development trends in Lighting industry network marketing as most of lamps made by glass products are easily damaged and also under transportation. How the lighting companies to stand out in the tide of Internet marketing?

Network marketing incoming tide, beach-goers becoming

The survey date show led street lights that in most household, lighting consumption costs currently about 10 percent in renovation costs, and the proportion is rising. This means that the awareness in creating fashion home are constantly upgrading. All kinds of chandeliers-wall lamp, floor lamp, mirror front lamp, table lamp, night light emerging light at home which is not the only function of the lighting. More and more lighting is for the decorative effect of making the finishing point. When turning on the lights, the nightan is an embellishment. When turning off, it is also a piece of art in high-income people. So the high quality of life of people will be more focus on lighting in the home. Internet marketing expert Liu Dongming teacher said that this consumer trends determine the development direction of led lighting industry: First, the lighting industry must establish the brand, and know with the new media for brand communication; Second, lighting products must be more creative, the scale of customization is a necessity. To grasp these two trends, Internet marketing is the only way of each lighting business.

The search engine is the Internet age which is the most important direct contact with consumers. So a variety of product categories such as LED spot top ten brand, led lighting industry, lamps, etc. Keywords prices climbing higher and higher, but the problem is that when consumers know the companies and products, what the potential idea encourage them to purchase. So in this regard, “word of mouth’ has become the determining factor. And the word of mouth is from other consumers.
