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.

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.

 

The second chapter: LED and OLED lighting: only in the necessary places to use the necessary amount of affordable lighting

Provide the necessary affordable lighting for the necessary site

In the past, the concept of more light is deep-rooted in Japan. Therefore, adjust the brightness depending on the circumstances, the adjustment of the atmosphere, including the color, residential, office, cities, very few positive examples of these features. Using these features generally only commercial facilities.

The second chapter: LED and OLED lighting: only in the necessary places to use the necessary amount of affordable lighting

East Japan earthquake occurred in March 2011, under the influence of this concept began to change. This is because the reality so that people must be a substantial adjustment to run out like water the traditional way of life. Even now, in eastern Japan, every corner of the residential, office, cities still maintain a state of substantially reduced the amount of illumination light. For these experiences,” I did not need too bright” understanding has been expanded to open.

In ordr to cooperate with this shift in attitudes, LED lights regarded as the best light. LED can simply use the necessary amount of lighting where is necessary, and adjust the color temperature.

In order to support the advancement of affordable lighting, combining with the sensor automatically adjusts the light which is an effective means. This need to connect the LED lighting and led street lights sensors, communication systems, as well as its control, management of the terminal group of a variety of peripheral technologies and products. Improve the degree of integration between the original lighting companies alone is difficult to achieve cooperation and communication equipment manufactures and construction companies and other enterprises.

OLED lighting form fundamentally to change

As contribute to energy saving and LED lighting degrees of freedom can be achieved higher than the affordable lighting source, OLED higher anticipated. OLED and led flood lights is not yet fully operational and practical, the subject is also considerable. However, the OLED, hidden to overturn the traditional lighting concept innovative.

The most unprecedented light itself is light-emitting surface. All the existing light are using the point and linear light source to illuminate the space. When it need to glow, we just put the point source in a row with the panel shape of the shade cast out. Use OLED can directly implement the entire surface of the light-emitting lighting, capable of producing large-scale, uniform illumination apparatus.

Introduction of the main components of LED panels

Different from other LED lights applications, such as LED tubes, LED bulbs, LED panels did not follow the traditional appearance design. In fact, they are derivatives from LED backlighting technology. Pushing the boundaries of traditional design concept made LED panel lights fully develop their own advantages and wide spread all over the world.

 

LED panels can emit even rays, no glares, more delicate structures, very popular in offices, hospitals, luxury hotels and some other high-end leisure and entertainment. Their elegant appearances made them the No.1 for lighitng designers or interior designers. This article will give a small talk about the basic construction of LED panels.

 Different from other LED lighting applications, such as LED tubes, LED bulbs, LED panels did not follow the traditional appearance design.

Aluminum frames:

Aluminum frames are the main cooing sections for LED panel lights, simple but elegant. The most commonly used model for panel frames is ZY0907, which costs much less in metal mold and stamping. The die-casting aluminum frames can be designed into different IP levels (IP67 tops).

 

LED lighting sources:

The normally used LED chips for LED panel lights are 3528 (35mm x 28mm), 3014, and 5060. Here panel manufacturers have to do some tradeoff. 3014 and 5060 are relatively cheap but with poor lighting efficiency. Most of manufacturers prefer to use 3528, not for a good lighting efficiency but the designs of light grids is much easier for them compare with 3014 and 5060.

 

LED light guide plate (LGP):

LGP is a key design point for LED panels. The working principle is guiding the light (generated by side mounted LED chips) thought the LGP evenly. A poorly-designed LGP will cause an uneven light distribution. Most of the light will concentrate on the center while other areas are much darker. Even worse, the entire panel presents bright-and-mark streaks, which is very ugly. In order to increase the lighting efficiency, designers should create a competent LGP. The next factor needed to be considerate is plate quality. However, designers would not pay much attention on this part, since the luminousness of different plates only impacts very tiny influences on total effects. Generally, small sized LED companies prefer to use finished plates from other factories rather than design and produce their own LGPs. By doing so, they can save a large amount of money.


Zimbabwe plan to introduce LED street lighting technology

Recently, Zimbabwe was focused on a new plan: gradually introduce LED street lighting technology all over the country in next two decades. On 5th July 2012, Mr. Cllr Amen Mpofu, the Vice Mayor of Harare, announced that landscape lamps on main streets will be replaced by advanced LED lighting technology during 2012. In his words, this will be a new milestone for the capital city and even for Zimbabwe. Mr. Cllr Amen Mpofu also indicated that this project will be spread through the entire country and the estimated energy saving will be approximately 80%. “LED is the most advanced lighting technology at the moment. Our scientists have made a complete set of tests and proved that it really save a large amount of energy compare with other traditional lights, even sodium lamps and halide lamps. We can save a lot of money by installing LED street lights. We decided to put this money into public issues to enhance the government facilities to serve our people better. ”

 Recently, Zimbabwe was focused on a new plan: gradually introduce LED street lighting technology all over the country in next two decades.

In a later interview, Mr. Mpofu introduced the main steps of this project and discussed about the social economic benefit and environmental benefit brought by it. As mentioned before, the implement of this place will save nearly 80% electrical energy. According to a recent poll in Zimbabwe, more than 80% residents expressed their support for this project. “It went beyond my expectation, I thought previously less than 50% citizens would agree with this plan. But the results came out so good. It suggested that our environmental protection consciousness has been strengthened. ”

 

Zimbabwe Development Democracy Trust published a research report at the end of last month, giving out a series of experiment results and conclusions. In this report experts estimated that if LED street lighting technology were be used all over the country, the Zimbabwe Government would save 1.8 million dollars per year in electrical costs and maintenance costs. This was a conservative estimate, without considering the costs caused by environmental protection. Since LED lighting products generate much less human-hazard substances, people have no need to spend a large amount of money to depose with them during their operation. Although the aluminum alloy used as the main body of LED lighting products may cause damage to the earth, it is much better than other traditional lamps do.


The first chapter: LED and OLED lighting: only in the necessary places to use the necessary amount of affordable lighting

With the energy-saving development to replace incandescent bulbs and fluorescent lighting, LED lights, OLED the popularity of the shape of freedom increasingly been looking forward to. Only the necessary amount of LEDs used where necessary, the use of OLED all face directly luminescence, etc., and a variety of usage increasing possibility.

The first chapter: LED and OLED lighting: only in the necessary places to use the necessary amount of affordable lighting

Starting from the energy point of view, the use and production of incandescent bulbs as lighting the main is less and less. In Japan, the Ministry of the Environment and the Ministry of Economy has asked industry to stop production and sale of incandescent light bulbs by 2012, major companies have to comply with this requirement.

As an alternative light source, LED(Light Emitting Diode: LED) technology achieve rapid development. High luminescence efficiency, LED flood lights as “a new generation of lighting” has become the trump card of the energy-saving from the high cost of active use. With prices constantly going down, the LED will no doubt become a mainstream light source in the future.

Not only in Japan, the development of the affordable lighting in the world is also accelerating. The Case of Korea, the country is carried out in 2015, LED lighting accounts for 30% of the lighting plan. The United States and China and other countries are also promoting LED lighting investment.

As the next stage in the same state of the style LED lighting to replace the trend of the straight fluorescent lamps. Most lighting companies are currently in development and sales for the substitution of straight-tube fluorescent products.

LED lighting is for the purpose of energy saving at the same time, LED of affordable lighting can also have the effect which is not limited to substitute the original source. Bears the potential of the life and work of human change and lighting to get along the way.

This is mainly because that the use of LED street lights can achieve a high degree of freedom of lighting dimming and color.

For example, LED lighting is theoretically capable of fluorescent difficult to achieve the range of 0-100% dimming. Although fluorescent lamps can support the dimming of the products, yet it can not control the type from 0%. Moreover,  the light will shorten the luminescence life time as the existence of a low amount.

Vietnam LED market has great potential

Ho Chi Minh City has recently issued an investment certification to Kim Dinh (Vietnam) and Fawoo Technology (Korea), allowing them to establish LED lights (for residential and industrial purpose) production base in the High-Tech Park. This was a first co-operation between Kim Dinh and Fawoo Technology and cost them about 1.23 million dollars. They believed that Vietnam LED market has great potential.

 

SHTP indicated that this joint venture belonged to new energy industry, in line with the new energy industry development policy issued by Vietnamese government. In the beginning of 2011, SHTP accepted 4 new energy investments (7.76 million dollars in total), including HPT, Amvi biotech, and Vietnam Oil and Gas RD led street lights Centre.

Ho Chi Minh City has recently issued an investment certification to Kim Dinh (Vietnam) and Fawoo Technology (Korea), allowing them to establish LED (for residential and industrial purpose) production base in the High-Tech Park.

Ho Chi Minh City now has nearly 110,000 public lighting bulbs and around 110,000 bulbs for residential use. From the very beginning of 2011, Vietnamese government started to replace all old traditional public lighting instruments and installed new electronic ballasts, which can save more energy. Even so, Vietnamese government still paid an electric bill of 120 billion VND (Vietnamese Dong) and another 25 billion VND for maintenance fees. Government decided when VEEPL finished at the end of 2011, Vietnam Ministry of Industry and Commerce will continue to implement plan to replace core wire bulbs with high-performance lamps (this plan is also funded by GEF). It is expected that after 2014, the utilization of LED lamps in Vietnam will be more than 50%. Economic experts felt confident about Vietnam LED market.

 

Urbanization, urban infrastructure, rapid construction and development prompted a huge demand of lighting products. Vietnam’s urbanization rate was expected to increase from 27% to 45.2% by 2020. The implementation of urbanization and the rapid development of economy have greatly stimulated the demand for lighting products, both indoors and outdoors. Vietnam lighting market has entered a golden age.

 

In the next 10 years, Vietnam will invest over 60 billion U.S. dollars in the construction of roads, airports, ports and other public transport network. The Vietnamese Government has approved an urban renewal plan. By 2020, the total investment amount will reach up to 90 billion dollars in reconstruction of old urban. Also, in commercial areas, in hotel/resort industry and leisure entertainment, the Vietnamese Government prepared development plans.

 

All signs pointed out that in the next decade, Vietnam LED market will explode.


All LED are a minimum impact on the environment of energy efficient lighting

The new report of US Department of Energy(DOE) points out that LED lighting is significant in that incandescent bulb compared to the lower impact on the environment and the slight super-fluorescent lamps(CFLs). LED manufacturing and utility”in this report compare the life cycle of these three different bulbs including production, operation and eliminated. This report is a comprehensive study and analysis of three different bulb products: assembly, transportation and elimination on the energy and the environment. This is also the first open discussion of the report of all LED production process to support the Department of Energy to protect the public air and water, and to improve the competitiveness of US clean energy, and to assist the family and line number to save the costs of energy bills.

All LED are a minimum impact on the environment of energy efficient lighting

This is the second report of the Department of Energy assessment compared with the traditional light bulbs. The life cycle cost of environmental resources.

This report follows the previous report, which is published in February 2012″ “Review of the Life cycle Energy Consumption of Incandescent, Compact Fluorescent and LED Lamps” conclusions, and compare three different lighting sources wide-ranging implications on the environment.

The report points that the traditional fluorescent lamps(CFLs) and all LED lights are very similar in terms of energy consumption, both energy consumption are less than incandescent bulbs, and consumed compared to manufacturing and transportation, running most of the life cycle-energy. Because of the high efficiency of the running, consuming 12.5 watts of electricity and can be achieved and CFLs (15 watts) and incandescent bulbs (60 watts), the efficacy. 15 test report 14 shows the LED bulbs are three lighting among the most environmentally friendly lamps.

In addition to the dominant disposal, all aspects of testing existed. Compared to  LED bulbs, the impact on CFLs is larger than environment. The landfill would be after the LED inside the aluminum alloy material precipitation will cause great harm, The DOE report noted that, based on short-term improvement impact in the next five years,all LED on the environment impact of today is quite small.

When market-oriented wants to save money for the customers and company, the incandescent light bulb change to use to save energy in lighting. We can estimate that LED lights and CFLs impact on the environment reduce today’s 3 to 10 times.
