super bright led light bulbs and led flood light

First, what is the LED lamps for flood light?
LED lamps for flood light (LED Downlight) also known as the spotlight, projection lamps, spotlights, etc., mainly used to make the use of architectural lighting, as well as commercial space lighting decorative ingredients heavier, its appearance round party, generally have to consider the heat of reasons, therefore, its shape and Spotlights still have some differences.

Second, LED Floodlight features:

super bright led light bulbs and led flood light

Common market, LED (super bright led light bulbs) Spotlights basically is the choice of 1W high power LED (each LED component with a high luminous efficiency made by the PMMA lens, its main function is the secondary distribution of the LED light, which is two optical), there are a few companies because of the heat if handled well, the choice of 3W or higher power LED. Cast lighting, buildings and other lighting suitable for large occasions.

Third, what is the LED flood lights  (super bright led light bulbs) ?

LED floodlight  (super bright led light bulbs) is a point light source of an exposure evenly in all directions, the irradiated area can be adjusted in the scene in the performance of a regular octahedron icon. The floodlight is in effect, making them the most widely used light sources, standard floodlights used to illuminate the entire scene. Floodlights can be applied to the scene to produce good results. The floodlight is the most widely used in the renderings, a light source, the scene with floodlights coordinating role, to the birth of the good results. Uniformly in all directions from a specific point in the irradiated object, use it to simulate light bulbs and candles are best. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the camera range, or within the objects. Remote access to many different colors of floodlights in the scene is very common. These floodlights will be dark projection and mixing in the model. Floodlights illuminated area is relatively large, so the irradiation effect of the floodlights is very easy to predict, and this light there are many secondary uses, such as floodlights placed in position near the surface is the surface on to produce a bright light.

The factors of LED light energy savings

Most lighting designers believe that the quality of all the LED products are the same. Only a small part of the manufactures to produce high-quality LED. For applications that only used as a simple indicating the role of the low quality of the LED is sufficient to meet the requirements. However, in many areas of the requirements of consistency, reliability, solid-state instructions or lighting must be of high quality LEDs, especially in harsh environments, such as highways, military/aerospace, and industrial applications.

In the New York subway stations and other environmental, safety requirements are very demanding, the led light energy savings must meet the high quality requirements of the fundamental factors.

Distinguish between the level of LED quality factors? How to tell the difference between the two LED Lights’s? In fact, high-quality LED chip start until assembly is complete, during which there are many factors to consider. Tier-One LED manufacturing company produce excellent and consistent indicators wafer starting from the high-quality led light energy savings manufacturing materials, enough to make a good chip. Determine the conditions of the LED performance, the chemical materials used in wafer production process is a very important factor.

A 2-inch wafer can be cut out more than 6000 led light energy savings chip, there is only individual chip performance overall. A good chip manufacturer makes chips in the difference of color, brightness, and the voltage drop is very small. After completion of the LED chip package, many of their performance have big difference, such as perspective. In addition, the impact of packaging materials is quite large. For example, silicone has better performance than epoxy resin.

Classification ability

Excellent LED manufactures can not only create high-quality chips, but also has the ability to classify the color, brightness, voltage. High quality LED CHINA suppliers can only provide customers with consistent operating characteristics, while lower-quality LED suppliers only provide LED which is similar to the “mixed”.

For high-end, quality-demanding applications, such as the boundaries of the airport runway lights must meet the FAA-calls color and brightness specifications, to ensure consistency of performance and security, led light energy savings packaging is strictly limited. Packing poor LED is used in demanding applications which will lead to premature failure and other non-consistency problem which is likely to lead to major accidents. In order to avoid equipment shutdown and to ensure that the operating characteristics specified in the design of the LED reliable, high-end and quality demanding applications should avoid the use of “mixed” products. This point is very important.

LED lighting product in Central Africa Cooperation Working Conference Held in Beijing

In response to the national “China-After science and LED Lights technology partnership” appeal, in 2010 October the State Ministry of science and technology implementation of China and the Republic of Kenya higher education and the Ministry of science and technology on the construction of apropos signed ” “semiconductor lighting demonstration project” and the “memorandum of understanding on the establishment of high efficient in Vito network to illumination center memorandum of understanding”, effectively promote a semiconductor lighting cooperation, China-Africa Cooperation semiconductor lighting in February 24, 2011 working conference held in the Institute of semiconductors. The meeting about led lighting product was convened by the National Semiconductor Lighting Project R&D and Industry Alliance. The people who from the semiconductor lighting related companies attend the LED PROJECTS meeting.

At first, the government China Solid State Lighting R&D and Industry Alliance, non-semiconductor lighting cooperation projects on the development of cooperation in a report. Described in detail the background of the non-semiconductor lighting on the basis of the implementation of relevant national call, can improve the lighting situation in African countries and improve people’s quality of life, but also conducive to China’s semiconductor lighting companies to develop the African market.

The existing African LED TUBES market development experience in the business representatives and participants to share experiences and views on the lighting market in Africa. Fieldwork in the African market, a vivid introduction to Africa semiconductor led lighting product market conditions, market demand and product characteristics and market competition situation. Lighting market in Africa can be in divided into high low points, but overall, the African market for the product performance requirements are not high, simple, easy to maintain the universal demand of the product. On the project in Africa has a heated discussion about the difficulty encountered. It was agreed that Africa semiconductor lighting has a huge market demand, but the image and reputation of Chinese enterprises in African’s mind is not high and should take effective measures to quickly change and improve the image of Chinese enterprises in Africa. Delegates deeply appreciated the power of an enterprise alone. In the vast African market alone can not play the advantages of the enterprise and also can not meet market demand.

LED lighting industrial, the additional biggest problem is “hot”

Fourth, it is because the heat generated by the LED lights, so it needs for cooling. Compared with the light weight plastic, the thermal conductivity of the metal is much better, but also bulky enough.

Five, Light perception. In fact, it is not a fatal flaw of LED lighting. LED lighting industrial products under the case of the less electricity, and the reason for the issues of the heat for long time, it is because the LED lighting stimulate the visual sense.  But such light is too strong, and if with the quality of the shade or baffles, or in large part to address this glaring problems.

Six, with regard to prices, after read the first five principles, it is self-evident.

LED Flood lighting is not that energy-saving on the matter, the key is to make consumers feel affordable and reliable.

The word “hot” in LED lighting field is sensitive. A word “hot” make a number of enterprises exhausting and make many consumers are neurotic. In the area of LED lighting. LED lighting industrial brand in the Chinese market could get almost none. The reason is simple, it can not solve the “hot” issues.

China professional LED lighting companies seem to have a lot. In fact, except ChangFang light, Really bright, Qingshang lighting etc, most of the little-known small business in the name of walking a fine line. In fact, look at the entire China market, LED lighting products capacity is not large enough to hold up more than one billion people in China’s consumption. So LED lighting industrial gets hot. How long does it sustained? How to continue the fire? This is the number of LED lighting enterprises and the people involved in the LED products, we can easily see that put in the LED lighting industry, the most urgent and the biggest problem is the “hot” instead of “heat”!

We use the foreign machinery and equipment to produce chips, or chips imported from abroad with foreign machine package, and then the foreign machine package, and then the foreign machine processed into finished lamp, however, it is still hot, so then we sold superior products abroad and let the foreigners pick and choose. Why is the Chinese high-tech is always dependent on foreign? More certain businesses even “imported” as the back of the brand’s quality.

LED lighting industrial, the biggest problem is “hot”

Look at this summer, it is so hot, and take a look at this summer’s flooding floods. Not saving and environmental protection, it will be more severe.

After suffering a lot of natural disasters, people is just deep introspection. Energy conservation protection has moved. Government strongly support, a lot of enterprise have answered the calling. People are expecting one energy conservation environmental  protection revolution.

LED lighting is indeed the new energy-saving king, just a few years time, it made known to every family, and took up a hot LED Lights market. The market is hot, but it is helpless and pale. On the led lighting industrial, many of the good news once again full of each big website headlines and impact on people’s ear. Just now and then whoever dedicated people will be got down to as “the wolf came”.

We try to look at the LED energy conservation principle:

One, convert the electrical energy the maximum into light; two, make the most suitable for human visual senses light.

When we put the LED lamp compared with the traditional energy-saving lamps, we can clear judgment, LED lamps are energy-saving. Here, everyone will think that energy saving will be OK?

Let’s look at how the led lighting industrial affect the market. the heat issues, life issues, weight issues, efficiency issues, lighting issues, the price. In fact, more than six come from the energy-saving LED lighting principle link.

First, since there are heat issues, it means that the LED lighting and light don’t convert the lighting energy as maximize, even worse than the common fluorescent lamp.

Second, since the high heat production of the LED to the point of view can affect the cooling temperature, to the point of view, the temperature can be seen in general. led lighting industrial source, what kind of material can withstand up to tens of thousands of hours of hot baking? Of course, there will be such a high-quality materials, but the price would be prohibitive.

Third, about life issue. In fact, it is very simple. The heat of the LED chip will affect the life of the LED lighting source itself, resulting in bad light, but also affect the life of the LED lamps, PCB driver board.

Technology trends of led lighting product chips

Austria microelectronic sensor driving lighting department director Sajol Ghoshal points out, to promote the continuous development of led lighting product technology is the main factor of LED Lights regulations. At present, the construction of the new power plant has become very expensive, so in the future ten years, governments around the world are looking to significantly reduce energy consumption. In a building, a high percentage of energy consumption come from lighting. Therefore, the new forced regulations will affect lighting system design and installation of applications. The European Union is planning to phase out the inefficient light bulbs and has formulated regulations for commercial lighting.

From the historical perspective, led lighting product is a rough control of the electrical load, with a simple switch manual control can be further refined control. For example, the lighting is a rough control of the electrical load, with a simple switch manual control that can be further refined. For example, the California Assembly Bill 32 regulations require the building to 2018 to reduce energy consumption by half. Other building codes, such as California, the Title 24 proposed more specific requirement. Such as requiring the implementation for daylight through windows and skylights capture to reduce energy consumption, and requiring the building equipped with an automatic lighting control system. Currently, low-cost passive infrared detectors has been rarely used in the room. Through building system to control lighting can greatly reduce energy consumption, and provide users with a highly optimized lighting. In this regard, it is clear that there is still a long way to go LED Panel.

Therefore, to use the advantage of  LED power and  flexible lighting control will be the main trend in the next generation of lighting systems. The program allows the lighting system to adjust the brightness and color of the led lighting product of environmental changes in order to meet the environmental requirements, such as when there is sufficient daylight in the room or no one in it, the method can automatically reduce energy consumption.

Meanwhile, with the development of LED Tunnel residential and commercial lighting applications, the demand for dimming increases, but the incandescent lamps which used in SCR dimming is still here, so the dimming driver IC architecture design need to face a wider range of dimming compatibility issues.

Technology trends of the led lights chip

Tony Armstrong, Linear Technology Power Products Division director of product marketing, with the further development of the LED, its effectiveness or the ability continue to improve. Secondly, LED lighting have environmental protection characteristics, which no need to deal with exposure and disposed of in a common toxic mercury vapor in the cold cathode fluorescent lamp. Finally, incandescent bulbs, and often need to be replaced after about 10000 hours. However, the led lights can provide over 100,000 hours of life. These figures are outshone.

Texas Instruments (TI) Business Development Manager Han Gan analysis, it is well known that the LED driver model high ambient temperature, and the module thermal conditions is poor, leading to the LED Panel driver circuit has been working at higher temperatures, which will lead to the reliability of the led lights applications reduce, and shorten the life of a series of questions. So the heat had to highly considered. Reliability and safety regulations is very easy to ignore and part, especially before the enforcement of relevant provisions, in order to reduce costs, part of the LED lighting manufacturers will be omitted reliability and safety circuits, but this is precisely the long-term fundamental of the led lights industry developing and also the embodiment of the design capacity of LED driver chip manufactures. Different chip manufacturers provide programs, which increase the costs vary greatly.

The accumulate Technology Co., Ltd. Product Director Yu Zhongwei think that it should be noted that the shape of the trend of standardization, such as the US Energy Star and Japan PSE specification. In addition, the dimming feature is more and more noticed. Such as the traditional SCR dimming 1-10V dimming, as well as DALI dimming. Finally, it is to address the thermal issues arising from the requirements of the driver program. In addition to cost considerations, a more lightweight requirements, but also must take into account of the better electrical characteristics(efficiency, power factor, electromagnetic interference, output ripple, etc.)

Semiconductor lighting market, technical marketing manager Lin Zhiyan said LED Tube is essentially a low-voltage devices, depending on the color and the current, its forward voltage drop may vary between 2 to 4.5 V, and it requires a constant current to drive.

The perplexity faced by solar LED street lamp energy management contract model

According to the characteristic of “contract energy management”mode, a comprehensive analysis of the LED lights on the confusion of the process of implementation of  ” contract energy management “mode, and proposed the government to play a lending role, which is the current implementation of solar led street lamp in the city.

The perplexity faced by solar LED street lamp energy management contract model

As energy consumption country, China unit of GDP energy consumption is 3 times higher than in advanced countries. The production of specific power consumption of unit product is high from 50% to100% than developed countries. China is undergoing the transition from planned economy to market economy changing period. The original planned economy energy saving management system of solar led street lamp is more and more which can not adapt to the new situation, therefore, it is necessary to introduce and popularize energy-saving work based on market mechanism of energy-saving investment and service.

Energy management contract (EMC) is the arisen new energy conservation mechanism in the last century of 70’s. It is through energy service contracts signed with clients, for clients including energy audit, project design, project financing, equipment procurement, project construction, equipment installation commissioning, personnel training, recognition and energy saving service. And from the customer for energy saving in energy efficiency obtained profits of a business operation. Its essence is to reduce the energy costs to pay the full cost of energy saving project investment. This energy-saving investment mode allows the user to use the future energy-saving benefits for plant and equipment upgrades, reducing the operation costs, improving the efficiency of energy use.

The pattern has the following characteristics for solar led street lamp: one is the energy consumption enterprises without funds to complete the energy-saving technological transformation, which is so called “zero input”. second is the EMC liable for technical and economic risks, energy consumption enterprises pay to EMC payments from energy saving the project benefit, the user” zero risk”; three is the end of the contract energy saving equipment saving equipment and follow-up. and all the energy efficiency go back to energy consumption LED Downlight enterprises.

Contract energy management to a great extent handled the factors which emerged in energy conservation. It achieve win-win situation, and indeed a effective energy-saving invest mechanism, new pattern, which can be popularized quickly in the market mechanism and become the mainstream model of energy saving investment in Europe.

t8 high bay and led backlight

LED-backlit display has been a gradual increase in the proportion of the  notebook screen application, estimated that there will be more than 15% penetration rate in 2014, compared to conventional CCFL LCD screen, LED High Bay Lights (t8 high bay) has lower power consumption, thinner, better The color performance and other advantages, to meet the requirements of the consumer notebook battery work longer hours, more lightweight body, the color is more brilliant.

t8 high bay and led backlight

LED  (t8 high bay) is a way to directly convert electrical energy into light energy semiconductor components with traditional LCD CCFL light compared to the many advantages of LED backlighting technology. Notebook LCD panels, which are arranged in groups on the bottom of the form instead of the traditional thin tube. LED Lights instead of the thin tube, the original light guide plate thickness and a wedge-shaped design was canceled, and turn the light guide plate with uniform thickness and can be the thickness of the overall reducing.

The same time, the LCD system board can be placed to the bottom of the screen to integrate without superimposed on the screen, which is the reduced thickness of the entire LCD screen one of the reasons. Screen with LED backlight technology can achieve the purpose of thinner, lighter and more energy-efficient, this notebook is one of the most conform to their development, thinner and lighter has always been the direction of growth of the notebook computer products If you look at the recent Apple’s new world’s thinnest only 1.94 cm, the MacBook Air, you can feel this trend.

Notebook LCD screen with LED backlight with CCFL backlight to save power and lower power consumption makes the battery life of notebook battery capacity is unchanged longer. The other LED  (t8 high bay) with a relatively low voltage can work more secure than require high voltage to the CCFL. The display has always been a major energy consumer in the notebook computer, notebook battery life is too short, this advantage of the LED Products is attractive.

LED-backlit display screen is not perfect, the shortcomings are in terms of color saturation, in addition, its brightness is not strong enough, should be less than the current mainstream of traditional CCFL LCD brightness.

 

The future of new led lighting will subvert the concept of the lamp

In the large-scale entered ordinary families, many people are very curious. Future LED Lights lamp would be like what it is? The United States Department of energy said: solid state lighting is 50 years in lighting field is the most disruptive innovation technology.  Many people in the industry agreed, and think that new led lighting is subversive products. It born to reform the traditional lighting. In the current exhibition, a number of innovative product LED stunning debut seems indicating a trend: lighting in the future may be rewritten lamp definition.
The future of new led lighting will subvert the concept of the lamp

For example, GE has introduced a slim, stylish Lumination Lumination Series LED lifting light this year. The design is forward-looking, its ultra-thin light guide plate and the edge set of LED technology, the new led lighting for maximum efficiency,  compared with fluorescent, it has a longer life of the slimmer, more innovative styling, enhanced dimming ability and sense of design, lighting designers and end users can also tailored. Individuality and creativity integrate home decorative lighting. OSRAM launch OLED lighting products – PirOLED, which uses five removable ORBEOS flat reflective light staggered maosaic in the double helix lampholders. It can not only create excellent visual effects, but also send a beautiful diffused light.

“Now we see most of LED lamp, LED bulb lamp in the shape of our basic and traditional fluorescent lamp bulb.  GE Asia-Pacific LED lighting products general manager Wang Jian said,  it is because the LED lighting applications has just started, mainly to replace traditional lighting for the mission. The design is similar in appearance just considering that it is convenient to replace the traditional lamp concept of idea and easily accepted by consumers. In OSRAM Wu Shenbo of  Asia-Pacific division president seems simple, actually it does not reflect the LED’s best performance and features itself if it is just according to the traditional lighting profile produced by LED replacement lamps. New led lighting is a solid adjustable light source, which should display for everyone at its most ideal state.  LED small size, low power consumption, controllability characteristics, making it the release of the designer’s imagination more than traditional lighting.
