The “olive branch” threw to the LED outdoor landscape lighting business

 

Yesterday, Nanhai District, special SMEs service Nisshin light industry in rout held on-site banking institutions with the new light source enterprises have signed a credit ceremony, held in the processing trade business seminars. In the meantime, the rout 63 municipal streetlight EMC information is officially released, more than 80 companies to the scene.

 

In the backdrop of the energy saving, power consumption high-pressure street lamps became “big.” For this rout street plan to the area of municipal management of street lights by “EMC” model into the energy-saving and environmentally friendly LED outdoor landscape lighting, while the rout municipal jurisdiction of street light maintenance pipe raising projects bundled contract of urban road lighting system upgrade.

 

The successful companies provide free led high bay lights, the electricity savings, we returned to the enterprise. “The rout Municipal Office of the relevant responsible person said, 2010 63 sections, regional, for example, sets of 63 meter electricity is 1.385 million yuan , assuming that the replacement LED outdoor landscape lighting electricity decreased $ 500,000, then freed up 88.5 million as compensation for corporate. It is reported that relates to the 1749 traditional high-pressure bulb needs to be replaced, a preliminary decision that the entire cooperation period of 7 years.

 

“In fact, from imported materials processing and then export is tax free, but there are policy due to ignorance, to pay more taxes.” Foshan Customs South China Sea Office of the processing trade, regulatory chief of Zhou Bin said, began to think that know for sure, but in communication with the enterprise, many companies still are not familiar with the policies and regulations.

The comparison of lighting effects between mains led lights and CFL

 

The comparison of lighting effects between mains led lights and CFL

 

Two different types of CFL lamps were installed in different locations of the hall. The divergence angle of the two fluorescent lamps are more than 110 °, while the Cree mains led lights is only 18 °. The optical density of the center beam of LED products is significantly larger than the fluorescent lamps is much higher, fluorescent 300, while the led high bay light to the 4465, which makes the LED lamps can be more light is concentrated in the local area.

 

Three lamp power and luminous efficiency are relatively similar, so the highlights of the Cree LED application is not on the energy-saving and high brightness. In fact, the Cree mains led lights lumen output is only a little more than half of 23W compact fluorescent lamps. It has the advantage that the beam in a small conical body, especially for local lighting. Cree LED lights will emit less light in the wide-angle region.

 

In short, the Cree mains led lights can increase the contrast of art and the surrounding wall, the color of the art look more distinctive. Table II a brief description of the different lamps caused by different light conditions. Art in the top of the wall, as opposed to 23W fluorescent lamps, Cree LED, the average vertical illumination reduces, it will be more light is concentrated in the surface of the artwork. Able to analyze the contrast on the CFL is only 0.5, while the LED lights to contrast 1.9, which greatly enhanced the art lighting effects.

The long cycle of growth case of mr16 light fittings meet the bottleneck

The long cycle of growth case of mr16 light fittings meet the bottleneck

From global population growth, electricity demand, energy-saving trends in three aspects, analysis of the growth trend of the global LED lighting market in the next decade, the Topology pointed out that the Asian region will become the greatest grow thin demand for LED lighting. LED high bay. The Japanese market, for example, the 311 earthquake caused the power shortage crisis, it makes the LED lighting market in Japan early in2014 matured. In addition, Central and South American countries including Mexico, Cuba, Brazil, Venezuela to ban incandescent, mr16 light fittings, and power supply are insufficient toenhance the demand for energy-efficient lighting products, coupled with a lower requirement for LED lighting product specifications, is expected to become the future ofthe various LED lighting manufacturers one of the main area of the layout.

However, the global LED lighting market into maturity in 2016, will face a two-stagedevelopment bottleneck. First, mr16 light fittings, by the high price, the market is the lack of product awareness and other factors, market penetration is difficult to exceed 20% bottleneck,once across the threshold will enter the fast-growing outbreak. Second, subject to theLED product life of up to 20,000 hours, about eight to 10 years only to be replaced under the influence, when the market penetration to grow to 40%, may again be faced with thereplacement cycle is too long, mr16 light fittings, making the weak demand into growth the plight ofstagnation. Mainstream LED lamp cup in a market – the CPL light Cup over the useful life of 50,000 hours have been significantly more than ordinary LED lamp life.

In the long run, LED lighting products in the global government successively activated to ban incandescent policy, mr16 light fittings, coupled with new residential built-in LED lighting alterationslighting needs in emerging markets such as China and other rural and urbanization, the pace and promote LED advertising light boxes build driven by bullish factors, LED lighting era just around the corner!

The comparison analysis of LED street light costs

 

The comparison analysis of LED street light costs

 

The new LED street light costs have a higher purchase costs, but these excess costs in theory, with its lower power consumption and maintenance costs offset.

 

Lighting retrofit project, the LED replacement lamp all the work on the automatic control circuit, work 12 hours a day, five days a week, 52 weeks a year (3120 hours / year). LEDPAR38 announced the useful life is 50,000 hours, in accordance with the above use, equivalent to 16 years. The average life expectancy of two fluorescent lamps is 8000 hours, equivalent to two years and six months.

 

In the United States, different states or different geographical and commercial electricity price has a big gap. April 2011, the average retail electricity price given by the United States is about 0.1 $ / KWh tariff rate from Hawaii 0.284 $ / KWh to the Utah minimum .0695 $ / KWh. Generally speaking, LED street light costs, able to withstand the economic areas of high electricity bills, because they bring energy savings sufficient to compensate for their own high sales price.

 

CFL spectrum in the long-wavelength red range is weak, compared to halogen or LED lights, which appear to be biased in favor of the yellow-green. Cree led high bay light can provide better light quality, and the halogen incandescent lamp spectrum, with a high color rendering index. Color rendering index, two CFL’s index of 82, two Cree LED 93 Cree LED lights will be more in the red spectral region of the long-wavelength energy distribution.

 

The annual replacement cost of the Bonneville Power Authority CFLR30 lights about 424.69 $ 537.26 $ CFLPar38 including labor costs. In the same circumstances, the LED new lamp reset each year to spend about 275.56 $. LED lights in the 16-year life cycle will not damage or maintenance.

SMD high power led market calls for the LED engine

The rapid development of LED lighting Products, a mighty force competing to join the new company was born in the world almost every day, especially the interior lighting of the mass market, forcing traditional lighting companies to tap into joining. SMD high power led is an electronic product, it requires not only such traditional lamps that structure, the shell must also be given a variety of string, and parallel matrix LED lights source lamp board, AC / DC constant current drive power, aluminum or ceramic, etc. heat , SMD high power led manufacturers need to employ electronic, optical, structural design engineer; traditional lighting is only one electrical products, traditional lighting manufacturers design, structural modeling of the production of lamps, the light source —- bulb bought to the professional factory plug will be able to use universal.

SMD high power led market calls for the LED engine

LED lighting design variety prevails, the inconvenience to the production, use, and industrial management, in particular the transition from traditional lighting plant to the SMD high power led plant, or just entering the initial of the LED lighting industry, will feel overwhelmed, where to start as well? Just enter the led high bay lighting industry, in order to reduce the risk and cost, often only to buy off-the-shelf LED light source lamp board, AC / DC constant current drive power, aluminum or ceramic such as the radiator assembly. Traditional lighting plant owners as effort as well buy a light bulb, buy a ready-made “LED light AC / DC constant current drive power” module into its traditional lamp housing can be magnificent turn as a the new LED lighting. Dreams can come true!, LED lighting, LED light source and the AC / DC constant current drive power integration module.

Mains led lights voltage and junction temperature

However, in the discussion of the theory, usually about the PN junction refers to the ideal knot. In an ideal junction is not considering its bulk resistance. In the actual device, not only the memory of the PN junction region in resistance, the body region in a semiconductor material existence of resistance, resistance exist in the contact surface of the semiconductor material and the outer electrode, the electrode material for the existence of resistance, the electrode material and the outer lead exposure exists resistance, outer lead existence of resistance, and so, in fact, there are a lot of resistance. Voltage temperature characteristics of led high bay light is a positive function. The actual measurement of an LED VF not only is the PN junction barrier voltage EPN, but also includes the resistor voltage. This had an impact on the actual voltage – a function of temperature between.

Usually in the Test mains led lights voltage – temperature relationship in a static thermostat, give LED for into a transient current, and read the voltage value within a very short time. The purpose of this approach is to exclude the current the voltage drop across the resistor. Small current test results, does not reflect the voltage of the mains led lights in the normal current – temperature relationship. A large current, the parasitic resistance can not be ignored. Current increases, the higher the temperature the greater the voltage drop on the parasitic resistance. And the voltage on the parasitic resistance is a function of temperature, the voltage on the parasitic resistance with increasing temperature will be significantly offset by the PN junction voltage drop.

With the LED after another import indoor and outdoor lighting market, LED lighting prices have also dropped significantly, but the quality is poor also lead to many problems, it was noted around one after another set of LED lighting specifications, a number of mandatory lighting standard from 2012 onwardsthe road is expected to accelerate the vicious competition eliminated inferior, thereby bringing about the LED task lighting market reshuffle effect.

 

LED lighting applications has become increasingly common and diverse, the Taiwan Ministry of Economic Affairs’ Bureau of Standards in recent years have worked a number of LED lighting standards, norm-setting pace of following LED street leading countries in the world announced the end of 2010, enacted three common LED interior light standard, including LEDT8 straight tube lamp, LED Spotlights light steel frame light (including flat-panel lights), the industry pointed out that the relevant standards has been set, but the led high bay lamp after years of promotion, until 2012 is expected to expand the installation, as the Government import slowly add to budgeting operations, is estimated to be 2013 to 2014 is expected to release procurement tenders.

 

However, due to regional differences in climate and environment is too large, industry standards have not yet entered the national standards project despite the development of LED industry in full swing, by province respective dominant promote regional LED task lighting standards established, but according to the Development and Reform Commission recently LED lighting technical specifications, indoor LED downlight is expected to grant financial program technical specifications finalized in 2012 under the impetus of the continent’s second Five-Year plan, the Central announced LED interior lighting is expected to expand the implementation of priority projects.

Although the Development and Reform Commission has officially released the “China to phase out incandescent route map, and will be from October 1, 2012, prohibit the sale and import of 100 watts and above the general lighting incandescent, but this does not mean that last year, led high bay once by the LED will benefit from the favorable capital markets.

The high cost of the popularity of urban and rural temporarily reality

“At present, out of incandescent but also fail to LEDs, the LED current costs are still relatively high. Xuhuai, the Secretary-General of the China Illuminating Engineering Society,” China to phase out incandescent road map “after the release, led yard lighting immediately triggered the LED stock rose, I think it is not very rational.
Xuhuai is made as stated above in the press conference held in Beijing on February 8 “TM – Come out incandescent”.

By the end of 2010, the penetration of efficient lighting products in China has reached 80% penetration rate of energy-saving lamps in 2010 than in 2009, an increase of four percentage points. In contrast, the popularity of the city work better, the China market, there are approximately 1.3 billion incandescent, of which about 10 million in rural areas.”

Incandescent lamps with the exception of a few hotels, most rural families to allow them to dozens of dollars LED replacement a few dollars incandescent, I am afraid there is no financial subsidies is impossible. “Xuhuai.

According to Philips (China) Investment Co., International Liaison Director of Ye Ming, China’s LED market applications is undeniable that already lead the world, is the fastest growing countries. Based on this, he believes that “as an explosive development of the industry, the LED will eventually replace other light.”

However, some analysts pointed out that China’s achievements in the application on the market mainly due to the “10 City, 10000” program. “Ten City, 10000” pilot urban research statistics, led yard lighting the 37 pilot cities have implemented a demonstration project of more than 2000 applications, LED lamps more than 4.2 million.

In this regard, China Illuminating Engineering Society Deputy Secretary General Liu Shiping said: “80% of the continent the street is a high-pressure sodium lamps, the luminous efficiency of 120 lumen s / watt, itself a high luminous efficiency, the development of more mature and LED trying to replace high pressure sodium, to his demanding led yard lighting LED experiment life of 20,000-30,000 hours, a single sodium lamp life of 12,000 hours is sure to ensure. ”

According to Liu Shiping, a 400W high pressure sodium lamp, and even the power is not more than 1000 yuan, but an alternative to 400W high pressure sodium lamp LED 5000-8000 yuan, or even close to ten thousand yuan. “This money, whether government or enterprises to pay the costs are too high. Developed areas able to absorb the cost of okay, led yard lighting but in less developed regions, first from the street lamps began to apply, but affect their future marketing.”

However, in China, the health system energy saving is still a new field, super high power led, but the LED hospital lighting with its bright prospects to attract the attention of many LED companies.

So, the requirements of the hospital system, whether the light environment what? Hospital professional LED lighting market prospects be? Grazing hospital professional LED lighting market cake? This article will be a professional perspective, super high power led, focuses on the hospital professional LED lighting market space and marketing strategies.

A Hospital professional LED lighting

A modern hospital to light environmental requirements: functional, clean and sophisticated

Hospital as a place of life-saving, the need to create a spacious and comfortable atmosphere, clean and quiet environment, super high power led, in order to give full play to the hospital, directly or indirectly impact on health. The modern hospital has grown from a mere social welfare into the general hospital of the business operations and modernization on behalf of management. The first impression of the patient into the hospital to determine the future of the hospital trust, which will directly affect the competitiveness of hospitals in the social market economy conditions. Hospital lighting is different from other places lighting, led high bay and more stringent requirements.

The construction of the hospital wards, clinics, medical technology and a variety of medical services and facilities, lighting requirements are also different. Good lighting effects to allow patients to relieve negative emotions, in a bright and comfortable environment so that patients can feel at ease to wait for treatment and treatment for the treatment of positive effects, super high power led, and to ensure the health workers to complete the work quickly and efficiently. alleviate the health care workers mental and physical fatigue, improve work efficiency. Good lighting design to consider the patient’s response to the lighting environment to avoid patient discomfort and resentment caused due to the lighting layout or poor choices, as far as possible to create a harmonious and comfortable medical treatment and recuperation areas. Conversely, if the lighting system is poor choice, super high power led, it is easy to become a place of bacteria, dust accumulation, will result in electromagnetic interference, direct impact on the hospital’s equipment life.

Hot invisibility cloak technology will seperate LED outdoor led spotlights?

Hot invisibility cloak technology will seperate LED outdoor led spotlights?Physicist Organization March 26 in the latest issue of “Optics Letters” magazine, the French scientists confirmed that many of the principles of optical invisibility cloak technology able to develop the transfer object to focus on certain hot thermal stealth or a regional “hot invisibility cloak.” The scientists said that the latest technology is expect ed to better control the heat dissipation in electronic devices, outdoor led spotlights, is also expected for the aerospace and solar technology.

At present, the progress achieved in the field of invisibility cloaks are based on the transformation of the basic principles of optics, which relates to the use of metamaterials and use it to allow light to bend, outdoor led spotlights, around the propagation of light in a space rather than through the space. For this reason, the Aix-Marseille University and the French National Scientific Research Center (CRNS), a joint researcher Sebastian Guna You led the team decided to clarify whether the same method can be used for the thermal diffusion.

Guna You said: “We conducted this study the main objective is: to use the conversion of optical tools, outdoor led spotlights, the success has been achieved in the field of sound and light ‘invisible’ to control the proliferation of hot.”

Guna You explained the basic principles of the latest technology and optical cloak, but there is still a critical difference. To date, the cloak to the trajectory of the operating wave for the center, including light and sound waves, LED high bay, but the biggest difference of the thermal field of the wave field contains the physics of the phenomenon of thermal diffusion rather than wave propagation.

The Guna You said: “is not a heat wave, it just spread from high temperature to lowtemperature, outdoor led spotlights, therefore, in these two areas from a leading role in mathematics and physics is very different principle. For example, the wave energy long distance travel attenuation is small, but a very limited range of temperature diffusion.

In order to create a hot invisibility cloak, Guna You and colleagues will be converted to optical principles of physics applied to the thermal diffusion equation and found that “hotcloak of invisibility” technology can be achieved.
