The study on led outdoor lamp heat sink design

Because of the complexity of the work environment of the outdoor lighting, subject to the influence of temperature, UV, humidity, rainy day, rain, dust, chemical fumes and other natural conditions, the serious problem of the LED light failure will be caused. Therefore, taking the above factors into consideration, the outdoor lighting designers should consider these external environmental factors for the LED outdoor lighting when the outdoor lighting designers do the design.

The study on led outdoor lamp heat sink design

Here, we would like talk out the study on the outdoor LED lamp heat sink design

The radiator is a very important part of the LED outdoor lamps which its shape, size, heat dissipation surface area should be designed to be consistent to the benefits. The luminous efficiency and life is affected by the high operating temperature of the LED light. The radiator is too large which will increase the consumption of materials and the product cost and weight and it will make our products competitive decline. Appropriate design led light heat sink is essential. The radiator design has the following sections.

1, A clear LED outdoor lights require cooling power.

2, Some of the parameters used in the design radiator: the metal specific heat, the metal thermal conductivity, chip resistance, thermal resistance, ambient air thermal resistance, ect.

3, The use of the scattered type ( natural convection heat strong wind cooling, heat pipe cooling, as well as other thermal cooling way). From the cost comparison: natural convection cooling cost a minimum, strong winds, the cooling medium, high heat pipe cooling cost, jet cooling the highest cost.

4, to determine the maximum permissible operating temperature of the LED lights (ambient temperature plus temperature rise permitted lamps)

5, Calculate the size of the radiator, cooling the area and determine the shape of the radiator.

6, Combine the radiator and LED outdoor light into a complete lighting and power more than eight hours at a room temperature 39 ° C – 40 ° C environment, to check the temperature of the lamp to see if it meets the cooling requirements in order to test correctly. If it not meets the conditions of use, it will have to recalculate and adjust the parameters.

The representive of NPC strongly suggest to develop energy-efficient lighting industry

HU Changsheng, NPC deputy and mayor of Suining City, Sichuan, said that the reform and opening up 30 years, China has made great achievement in increasing energy saving as the main structural adjustment and technological transformation efforts, energy, water and resource conservation. With the rapid economic development, population growth and the improvement of people’s living standards, the macroeconomic performance in resource constraint contradictions have become increasingly prominent, and tight resource situation also became increasingly prominent.

The representive of NPC strongly suggest to develop energy-efficient lighting industry

In recent years, the semiconductor lighting industry has developed rapidly. The United States, Japan, Europe, South Korea and China’s Taiwan region has strong advantages in different areas, and t he global output annual growth rate maintained at more than 20%. After 30 years of development of LED industry in China, it has initially formed a relatively complete industrial chain including epitaxial wafers, chip preparation and packaging, as well as the application of LED lights. Although China has become the world’s largest energy efficient lighting products manufacturing base, however, industry concentration is low, and domestic market share is limited, even a considerable part of the business just OEM production.
At present, under the tension power resources of our country, about 14% is consumed in various areas of the lighting. To this end, China has started a green lighting, semiconductor lighting project. The State Council set up a special team of energy conservation and emission reduction. Since 2008, 150 million energy-saving lamps are spread across the country in three years, 50 million a year; Residents purchase the promotion of energy-saving lamps, state subsidies by 50%, the bulk of customers to purchase, state subsidies of 30% .
In order to further promote the development of efficient lighting energy and efficient lighting industry inChina, and also to accelerate the pace of western efficient lighting industrial bases, HU Changsheng hereby submited the following recommendations:

Make out the construction of supporting regulations and standards “Energy Conservation Law” as soon as possible. Such as “energy monitoring management approach”” the state organ office buildings and large public buildings indoor temperature control approach ” “high-energy special equipment energy-efficient supervision and management measures “,and so on in order to further enhanced the operability.

The prospects of LED commercial lighting

LED commercial lighting is very popular, how its prospects for future development will be?

We can analyze from the following levels:

First, from a technical level: LED commercial lighting owns more advantages than the traditional commercial lighting.
Used in traditional commercial lighting fixtures includes incandescent, halogen, fluorescent, energy saving lamps, metal halide. Compared to these traditional lamps, the white LED has five major advantages: 1, energy saving, LED commercial lighting is generally only 1 to 10W low power consumption. 2,environmental protection, LED recycles light, But energy-saving lamps, halogen lamps has a major recycling problem as all these lights contain the pollution of the environment of the metal elements (such as mercury). 3, security, LED light fever is not high; 4, long life, 5, the luminous efficiency and changeable color. 1W LED lamps can usually reach 90-100 lumens, equivalent to a general light source 5-6 times the light efficiency.
Second, from the market level: the prospect of LED commercial lighting market is broad.

LED commercial lighting

1, the R&D cost continue to decrease.

LED’s core technology is the LED chip technology. With the thawing of the LED chip technology patents after 2010, the prices of the LED chips decreased substantially and so did the cost of the LED commercial lighting products. It will be a happy event for the LED manufacturers as it will improve their enthusiasm for production.

2, Brand is slowly rising.

3 , the application environment has become increasingly public.

In fact, LED commercial lighting concept has become vague and some products are no longer limited to high-end commercial spaces.
4, The channels gradually approach the traditional business.

At present, LED commercial lighting promotion mainly reply on the model of the traditional business of commercial lighting channel.

Through the above analysis, we can see that the LED commercial lighting will tend to be more and more mature in the future. The stability of the LED products will be enhanced further. To the people who are in LED field, the inexpensive, high-quality LED lamps are the key development for the LED commercial lighting. In short, a LED commercial lighting war is inevitable. Emerging brands, export sale brands will be the leading force of leveraging traditional domestic business and also the mainstream of the commercial lighting.

The large scale application of commercial LED is not a dream

In fact, it is zero investment and zero risk for our mall. The LED down lights manufacturers is of warranty period of three years. Within three years, the light fades should be controlled less than 20%. If it is over 20%, you will enjoy a free replacement. Theoretically, the commercial LED lamp life can reach 50,000 hours which means that it can use over a decade. Conservative speaking, it can be used for three years now. Year and a half section of the rest of the electricity can be used for costs, as well as earnings in a year and a half.” Chen buggy analyze the economy of the large scale application of the commercial LED lamps from the vision of a businessman.

In Hefei, the reporter saw that the second, third, and forth floor of Qingyu clothing mall use the commercial LED lamps for lighting. Times Square in Hefei, Anhui manufacturer have entered the installation phase and plan to completely transformed into the semiconductor lighting step by step. Hefei Times Square Engineering Manager Zhou Dongjun said: “After comparative testing of semiconductor lighting and traditional lighting, energy saving is up to 75% or more.”

In addition, the reporter saw the field of semiconductor lighting of the the Hefei airport terminal building, 9.5 meters high waiting hall showing the rich texture of the light intensity. According to reports, this is the world’s first airport terminal semiconductor lighting Civil Aviation Airport. Another case is located in the Economic Development Zone of Hefei Jade Avenue and Danxia Road Interchange Jinshui, fairy gardens to residential real estate in the heart of University City. This item was included in the “Eleventh Five-Year” National Science and Technology Support Program, which is an integrated system engineering, solar photovoltaic, green lighting, semiconductor light source applications, fire emergency lighting, network management, infrared alarm monitoring, digital system control and more items integrated high-tech, solar public lighting electricity. The project is saving lighting 111 million kWh / year. This project uses a semiconductor performance lighting technology, energy-saving basis up to 50%, a 95% reduction of the total energy consumption through the use of renewable energy.

The measures to solve the problem of environmental pollution of China’s Lighting Industry

In order to control and improve the generation and diffusion of electric light in China in the production and use of hazardous substances, I propose the following solution.

First, to strengthen the management of the production chain and led down lights, from the source to reduce the amount of mercury.

Lighting Industry

To strengthen the management of electrical Lighting Industry production enterprises from the manufacturing part, the main purpose is to reduce the use of mercury in order to reduce the threat of mercury into the environment from the production processes. Through the standardized management of production enterprises, to improve the level of technology, workmanship and the equipment, and improve the overall level of the electrical lighting manufacturing industry, the main measure is to make out the development planning and encourage the development of clear deadline for correction and immediate elimination technology, process and corresponding enterprise development and strict production system of administrative examination and approval.

Second, to make out the mandatory standards of the industry and to establish the compulsory product certification system.

China still didn’t have the mandatory standards on the mercury content of the fluorescent. The actual situation of the producing is that fluorescent lamp of the mercury content of the level difference is large, a high reached 40 ~ 50mg,and low can be controlled in the 5mg or less. To control the content of Lighting Industry electric light mercury is not a technical problem, but a problem of national policies and policy enforcement. Production technology is mature amalgam and mercury pills can effectively control the use of mercury amalgam and mercury pills can be extremely precise control of the amount of mercury in each lamp.

Third, to detect the production enterprise production environment at a regular time, to assess their environmental impact.

State environmental protection departments should regularly or irregularly detect and assess on the production environment of production enterprise. For the enterprises which cannot achieve to this standard, should be make a different punishment according to their level of environmental pollution.

Lamp collection points should be established at the the Lighting Industry electrical point of sale.And establish a recycling network in parallel with the sales network.

The key to contraint O LED and led lighting bulbs are cost

According to market research firm SBI (Specialists In Business Information), It is  estimated that the market size of global LED lights and OLED today has more than 5 billion U.S. dollars, while the United States occupies a market value of $ 1,000,000,000. The SBI further Estimated that the market size of Global led and the OLED in 2013 will reach $ 14 billion, while the United States is up to $ 3 billion market size.

Why led and OLED technology can become one of the best industry in the future in potential growth? Because the efforts made on the current global green energy is more even than ever. This is influenced by the oil and other rising prices and the global climate change in the first half of 2008.

led lighting bulbs

Compared to the traditional incandescent. Led is of much efficiency on the energy conversion. Generally speaking, the LED conversion efficiency is 80%, but the incandescent is 20%. For example, the energy use can be reduced to 92% if using led traffic signals instead of using incandescent traffic signals.

From a long point of view, many places around the world will no longer need to build too many power plants if more and more LED and OLED application markets are established, even if more and more people are in higher demand for electricity. This is because LED and OLED can reduce everyone’s electricity consumption. So once the higher the penetration rate of led lighting bulbs, the existing power plants is enough to meet demand.

However, SBI also reminds that the cost reduction still need some time even if there are many advantages of LED and OLED.

Therefore, one of the keys is to hinder the popularization of LED and OLED cost. Once the rapid price declines, and perhaps LED and OLED market scale will be larger and more popular.

Taiwan is now also actively working to develop led lighting bulbs market. Ministry of Economic Affairs Energy has enlisted NT 2-300000000 yuan budget. After the LED street light is set, it will expand the replacement of LED street lights. LED inside estimated that the overall LED market in Taiwan will have 400-500 billion opportunities.

The development trends in 2010 high power led lamp

With the entry of foreign capital in the lighting industry, it appears the international situation of the domestic competition. They are trying their efforts to increase the energy-efficient light sources and different grades, patterns, the development of the different uses of lighting and to accelerate the green, to promote the development and application of energy-saving light source products. Meanwhile, building own brand is the sustainable development of the lighting industry. China’s high power led lamp industry is facing unprecedented opportunities and challenges, and the resulting huge commercial interests also become the focus of attention of the lighting manufacturers.

Review and Outlook crossover between the development trend of China’s Lighting in 2010 has been presented:

After striving to foster domestic consumer market in year 2009, the Chinese government’s policy on the real estate market began to return to the rational. This will be a major initiative for the development of potential savings in the lighting industry, squeeze the bubble, which will have a profound impact on the industry;

Second, with the introduction of the national energy saving policy, the implementation of energy conservation and environmental protection will be the slogan of the Government to the reality of the market performance of China’s energy-saving light source industry which is an unprecedented opportunity and challenges to the Chinese lighting industrial

After nearly three decades of development, the Chinese high power led lamp industry has begun by the power of product competition to channel competition, competition to capital force and service force by industry brand competition era;

Fourth, the Chinese lighting industry will show a competitive differentiation, and the regional brand will enter the local government’s agenda;

Fifth, with the national energy policy having been introduced, high power led lights lamp will turn into the era of large-scale outbreak of the market.

Upstream manufacturing companies will be fighting for each other, entering into complementary advantages, differentiation, integration era capitalization;

Downstream market will appear the era of Union, strong capitalization integrated chain, branding, information technology, business management standardization.

The development of new energy lighting will usher in a new spring

In the last month, the trend of the international market price of crude oil concuss disk cross. Before the week of three major crude oil index last week, there was a substantial rise, approaching the $ 80 mark, international coal prices also gradually lift domestic coal prices in some enterprises raised continue to rise, the price of coal, electricity production and restore a variety of factors such as the carbon and led lights price to maintain the shock.

Development and Reform Commission limit the fan machine and the production capacity of poly silicon materials, guidance to maintain the healthy development of the new energy industry, new energy near the end of the Copenhagen conference, the global rise of “low-carbon” boom, China’s “Twelfth Five-year” may be the greater impact, with the economic recovery, photovoltaic, wind power and other new energy projects to invest and advance wave upon wave, new energy investment boom in the ascendant.

On October 16th, Deyang World Epitech semiconductor energy lighting industry base project signing ceremony was held in Chengde. The project settled Jingyang Industrial Development Zone. It is a large-scale semiconductor energy lighting company as one of the core strengths of the research and development, technology, products, etc. The project will be an important part of the Denyang construction energy industry.

Southeast Asian dignitaries are frequently visiting the Deyang new energy enterprises. On October 15, the Vietnam National Electric Power Company signed a contract with Dongfang Electric. As Chinese enterprises get a lot of project in the field of Vietnam power construction, Dongfang Electric Adds 600000 kilowatts super critical thermal power equipment orders.

At the same time, the person who are in charge of the China Energy Conservation Investment Corporation, China National Machinery Research Institute, etc, have arrived Dirong to visit Dongfang Electric. The talking are focusing on “low carbon economy”, “new energy” projects.

The development of new energy will usher in a new spring. The new energy sector is also expected to brace. From valuation and performance expectations in the short term is still the most optimistic about the bank and real estate stocks. New energy stocks have been adjusted two quarters. A series of policies stimulate substantial improvement of the fundamentals, such as the Copenhagen conference is expected to occur.

The innovative storm promote LED commercial lighting model change

Recently, the retail giant New World Department Store 18 shopping centers in mainland China ask Philips to complete the LED retrofit lighting in public areas. One of the New World Department Store said, there are two changes after the transformation of the mall space. On the one hand, the energy-saving rate more than 30% of stores per year, each home can save hundreds of thousands or even hundreds of million dollars of electricity costs, which is sufficient to recover the full cost of 2 to 3 years; On the other hand, the lighting upgrade products display after the transformation and enhance the attractiveness to customers and to create a more comfortable and enjoyable environment for consumption.

LED commercial lighting

The study shows the layout of the different colors of LED lights at the mall will be able to upgrade to the 2% to 5% of sales. Bright and cool shades of light can make consumers spending 1.93% of the amount for the purchase of the product, but as the lights down warm figure can reach 5.5%.

Today, LED technology is not just enhance the sales of the shopping malls, LED commercial lighting era for the field of commercial lighting will be a great change for the brink.

Innovation Storm

It can be predicted that it can create innovative LED changeable lighting atmosphere and the trend of peers with consumers shopping motivation and change. It gives a commercial shop more imagination and inspiration to help businesses and to create a pleasant shopping environment which can greatly enhance the brand image.

The LED magic is a good interaction that can make people’s desire for consumption,  psychological and light contrast of commodities, therefore it can be called light designer. Its good business prospects, the unprecedented national efforts to promote the LED industry, major companies also invested heavily in research and development of LED. According to the reporter, only Philips, the annual investment in the research and development of LED commercial lighting is hundreds of millions of dollars.

“Today, each brand has been more and more attention to the application of LED in the commercial field. Its changeable light can greatly enhance the expressive power of the brand, thereby increasing competitiveness.”

The confusion on LED domestic lighting enterprises export to domestic

By the impact of the economic downturn in Europe and the United States, domestic LED enterprises export orders showed a sharp decline. At this critical moment, the domestic LED enterprises have to invest in the domestic market in order to seek the way of salvation of “domestic export sector,”.  According to related statistics, the majority of orders for 80% -90% of the domestic LED enterprises comes from the export. Domestic market situation has failed to open and the export enterprises phenomenon is extremely uneven. With the government promotion of LED energy-saving products and preferential policies, the domestic LED domestic lighting market gradually show an upward trend.

domestic lighting

Desire to purchase is less for consumers
Currently, It is much more difficult for LED domestic enterprises to do the domestic market than export. One reason is that the prices for LED is much more expensive than the common energy-saving LED lights which is not widely accepted by the rural and urban which develop slowly. With the plan of the phase out of incandescent lamps, LED huge market in the future will appear in the remote areas of rural and backward. On the other hand, domestic people didn’t have a overall understanding of the LED energy-saving lamps. They only care about the power and the prices of LED and also do not have a understanding about the relevant parameters so they didn’t have a high degree of interest in their LED products. Therefore, it is necessary to strengthen the awareness of the benefits of LED domestic lighting.

“The foreign LED market competition system is more complete. As long as your products is superior in quality, it will sell better. While the domestic market is relatively immature, the key of the competitiveness of the product stems from the cheaper price, public relations capacity and personal connections. “Gu Wenjun pointed out that the competitiveness of this industry” hidden rules “phenomenon distorts the LED business, which leads to the low concern on the product quality for manufacturers and further limiting the benign development of the domestic LED industry.
