Outdoor led landscape lighting lit up Moon Bay Park last night.

 

Moon Bay Park night has been very popular with nearby residents are welcome, but from February this year, many attractions led high bay with night is not bright, street lamps began to strike phenomenon. Jinhua Economic and Technological Development Zone Management Division of Public Utilities staff told reporters that the street lamps and outdoor led landscape lighting with suspended lighting, mainly because of the handover of the park management procedures has not been doing a good job.

 

According to reports, Moon Bay Park infrastructure improvements completed in 2011, due to public facilities have a shelf life of the issue, temporarily has been in the management by the construction side. “The shelf-life, landscape lamp lights is green belt two years, in order to consolidate the quality of construction.” To February of this year shelf life, street lamps and outdoor led landscape lighting management should be handed over to Jinhua City Economic and Technological Development Zone.

 

However, bad weather, before rolling the rainy weather, affecting the progress of the project acceptance procedures for the transfer up to now no completely handled. Utility management, deputy director Li Pengbin also admitted that drag is a bit long. He said that while these days it does not rain, they will speed up fight for good handover completed this week, and soon the beautiful night view of the park re-lit.

 

The Office staff also introduced to the holidays, the park was increased, the garbage is also greatly increased. “Sometimes temporary additional three or four cleaning staff are not enough for outdoor led landscape lighting.” The uncivilized behavior of some visitors, seating, landscape fake stone and even the floors were wood damage. The entire park facilities maintenance pressure.

Intelligent led task lighting, automatically adjusted brightness

Intelligent led task lighting, automatically adjusted brightness

 

According to reports, Taiwan Industrial Technology Research Institute (TITRI) set up a Theme Pavilion in Taiwan International Lighting Technology Exhibition on 13th last month, to show its research productivity in LED high bay lights. During this exhibition, TITRI demonstrate their omnibearing applications of LED lighting technology, including steel frame LED lighting, intelligent LED lights, led task lighting, LED outdoor landscape lights. Most of them have market potentials.

 

Intelligent led task lighting satisfies the standard of office lighting. It can completely replace the existing traditional T8/T5 tubes. At the same time, it can automatically adjust the light color temperature though the intelligent embedded control system.

 

Usually the color temperature is about 4000K in the morning, around 6000K at noon, about 3000K during the night. This Intelligent led task lighting can automatically adjust its brightness depends on the increase or decrease of sunlight or other auxiliary lights. It can maintain the same illumination without affecting lighting quality. Meanwhile it can offer comfortable lighting environment with tiny energy consumption.

 

Theoretically, led task lighting can maintain a relatively long life. Lighting failure usually occurs on DC/AC convertor, which is removable. The only thing left to be finished is to integrate all the circuit part into the intelligent control system except for the DC/AC convertor. This method can efficiently reduce costs, extend the service life.

 

In addition, TITRI also exhibit A19 Bulb packaging technology. The entire LED bulb changed to use heat plastic. Its light emitting angle is larger than the normal LED bulbs. This LED bulb is suitable for indoor decoration, lighting up a large range.

Night instead of something of spotlight led light, called the belief

Night instead of something of spotlight led light, called the belief

(A) We often order an immediate duty-bound, it is difficult to not tell arrival will the future and dreams die without any hesitation. Like you read an inspirational speech, he suddenly playing with blood, home word but two days after their colors, after a few days you saw a tourism-related article, led high bay, whim to check the internet hotels and plane tickets, but after a few days, always there is no laid down. spotlight led light.
The fact is, you can run away to find ten thousand excuses, such as the passport is not good with visas too hard, ah is not good English, the language barrier ah, studies for re-ah, the acclimatized ah, no companions ah, too busy with work ah , the family do not trust ah, lovers oppose ah, security safeguard ah, recent manpower ah, frail and ah … reasons to leave only one: to go!

Mouth shouting want to travel has been to stay put, if we are thinking about a dream confused classified as fantasy, if we want the good faith has been defined as hypocritical, how should we do about LED street light? spotlight led light. If we want to own life is not so plausible, if we want the future do not hate now, if we want to hope in the darkness and adversity can still see the choice of brave. Then we must find the things of the night, instead of the sun, that is faith.

(B) In fact, wandering in different places came to is not easy, because most of this life is not easy and can not tell, this is a Lengnuanzizhi living conditions. Whether you describe a good or bad, are hard to not have the same experience empathy.
So there have been so for some time, spotlight led light. I particularly dislike telephone, network and e-mail such a thing, because how far it can only be constantly reminded of the distance between us. I desire nothing more than someone can tell me face to face chat, even if only ten minutes or Experienced a long-time love long distance relationship die a natural death, but why Actually, I’m so unexpected, and probably make it too long but numb, or in fact, I fight my heart to know the outcome will be so. No emotional feelings, rely on to maintain then a line, let us think she was like to live in the Antarctic, and I live in the Arctic. Even if we were face to face conversations are like every time over the mountains in the heart.
Then the blink of an eye on the present, the most amazing things in this world, one day you find the fulcrum around you are falling down when you did not fall. People than their own imagination to be strong, especially when look back, will go a long way. It touches the life becomes more and more law school, class, cooking, with a few fixed chat with friends, spotlight led light. look at one hour and a half books or watch a movie, inspired by rush of the manuscript, and then sleep, quirks more and more more, such as cooking, be sure to put the song more and more obvious of led tubes, such as finishing the obsessive-compulsive disorder.

2013 to 2017 will be the “golden age” for LED lighting industry

2013 to 2017 will be the golden ag or LED lighting industry

IMSResearch market the analyst JamieFox in the 2012 British International LED Exhibition (EuroLED) said, the market value of the high-brightness LED lighting industry for general lighting applications reached a peak in 2017, then began to fall with the rapidly falling costs of technology. LED supplier’s “Golden Age” in 2013 to 2017.

 

Fox said that during this period, the LED market penetration is expected from the strong growth of a few percentage points to 10 percent in 2014 and 2017, 25%. Although the cost of the LED lighting industry in the next five years may be declining rapidly, but this is 2017, in order to hinder the growth of the market value of the general lighting applications in the field of LED chips.

 

However, after 2018, the market reached saturation, with the decline in LED prices and provide a long service life due to LED technology led lamp replacement rate, the field of general lighting applications, led high bay market began to shrink.

 

LED lighting industry in the broader market will usher in significant growth from the current $ 85 billion to $ 120 billion in 2017. But with the cost reduction and saturation of the market, ten years later, the market size will shrink to 105 billion U.S. dollars.

 

A key driver of cost reduction is one of the GaN LED chip production from the sapphire or silicon carbide substrate to the transfer of the silicon substrate, this new way of being the support of many of the major manufacturers in the industry, although varying degrees of success.

Mains led lights industry: waiting for the reborn

Mains led lights industry: waiting for the reborn

In fact, LED high bay is a new industry, but has fallen into production can be an oversupply of the plight of Many companies blindly expand production capacity, inventory piling up of a number of vendors. It is reported that Shenzhen Mains led lights technology and product research, development, production and application of the enterprise is about more than 2,000, most of the technical areas are LED packaging and application. High-tech enterprise engaged in the LED 97, 2835, Shenzhen City High-tech enterprises, accounting for about 3.5%. Related enterprises in Shenzhen City, is the only one of the chip production, the production of vital semiconductor materials, phosphor production enterprise is a no. Technologies, processes, equipment, key raw materials and so needs to introduce. Past two years, along with the prices of rare earth raw materials, energy-saving lamps of profit to drop substantially.

 

Blind development, last winter, a number of companies have fallen. Shenzhen Mains led lights Industry Association data show that last year’s collapse of Shenzhen LED companies have more than 80, another part of the enterprise in a semi-shutdown state. However, the tragic situation in the line of the second half of last year and allows the strength of the manufacturers to develop and grow. Reported Germany Runda has to enter the Mains led lights market in the United States, Japan achieved a breakthrough on the gains the United States and Japan 566 million yuan a single.

 

Standard non-standard factors, the market potential has yet to break out. “Ground on the optical official said, according to food safety regulator spot checks in 2010, Guangdong Province, the province has 53 percent of the Mains led lights do not meet quality standards.

Analysis for led lights for street lights trends in 2012

Analysis for LED lights trends in 2012

 

1) the heat of the lighting system

Commonly known as LED cold light source, led lights for street lights principle is issued a photon, electron after composite without the need for the hot process. However, due to the presence of Joule heat, the LED is illuminated at the same time accompanied by heat, but also for the occasions of high-power LED applications, the calories add up and cannot be underestimated, the led lights for street lights are different from the traditional incandescent, fluorescent and other lighting light source, the high temperature will shorten, or even termination of their service life.

 

2) to improve the color rendering

White LED widespread use of blue led lights for street lights superimposed excited by blue light, yellow light yttrium aluminum garnet (YAG) phosphor, the synthesis of white light. Because of its luminescence spectrum contains only blue, yellow, two spectrum, so there is a high color temperature, and low color rendering index, does not meet the general lighting requirements.

 

3) design of the lighting system of the second optical

Traditional lighting with incandescent, fluorescent light for a long time for a reference to determine the standard of optical and shape of the lamp, LED lighting system should be considered to get rid of the traditional lamp with led high bay module assembly, fully consider the optical properties for the The led lights for street lights source designed different lighting. The optical system design include the following several aspects: to determine the optical system according to the needs of lighting objects, luminous flux, the shape, the number of LED and the size of the power;

LED heat dissipation: Board level technology

LED heat dissipation Board level technology

Recent progress in TV, LCD, Cell-Phone, the PC (Notebook) and other portable use and living appliances and other electronic products, high performance, miniaturization, integration, Module, such as rapid. High-performance needs more energy consumption LED built-in electronic products, contrary to miniaturization and integration to the product of the size constraints.

Markets tend to improve the power LED package that can accommodate the design Maigin sharply reduce. Module of the heat issue is no longer simply a problem of the LED products, but the question of the overall System.

Heat within the LED heat dissipation package Chip effective management is not the product of electrical / optical characteristics of the problem, but as the impact of product life, reliability, manufacturing costs, and other elements. In particular, take the LED application products (led high bay), have different characteristics with the use of temperature, drive current power consumption rate of heat and light.

Hot if not well controlled power that occurs, it will make the products of the same specifications as the different light efficiency and directly lead to the competitiveness of their products. The high power consumption also has good heat dissipation structure of the product is the most competitive market of LED heat dissipation.

This column will be the Board level thermal cooling technology in the various elements to be resolved.

The concept and composition of the metal PCB, but it is necessary for LED heat dissipation technology.

The circuit on the main printed circuit board (Printed Circuit Board) is made ​​of glass fiber and epoxy composite with insulating layer FR-4 board.

How the White LED lights to maintain a long life?

How the White LED lights to maintain a long life

LED industry in the past in order to get the full white LED beam, once the development of large-size LED chips trying to take this way to achieve the desired goals. But, in fact, exert power white LED lasts for more than 1W beam but will decline in the luminous efficiency of 30% relative reduction of 20. In other words, if the brightness of the white LED is several times larger than the traditional White LED lights, the power consumption characteristics beyond fluorescent lights, then you need to overcome the following four topics: inhibit the temperature rise to ensure that the service life, improve the luminous efficiency, and Luminescence Properties of equalization.

 

Temperature rise solution to the problem is to reduce the package thermal impedance; to maintain the service life of White LED lights is to improve the chip shape, a small chip; improve the LED luminous efficiency of the method is to improve the chip architecture, small chip; The luminescence properties homogenization The method is to improve the led high bay packaging methods, these methods have been developed one after another.

 

Due to the increased power but will result in the package thermal impedance is sharply down to below 10K / W, foreign companies have developed high-temperature white LED, and an attempt to improve the problem. In practice, however, high-power White LED lights heat than low-power LED a few times more, and the temperature rise will make the light-emitting efficiency fell sharply. Packaging technology allows high-calorie, but the LED chip junction temperature there is likely to exceed the allowable value of the last industry finally realized that the heat dissipation problem is the fundamental method to solve the package.

 

Chinese decoding of led aquarium lighting in plant-lighting market

 

Chinese decoding of led aquarium lighting in plant-lighting market

 

Traditional plant-lighting industry can be divided into two parts:

Plant Lighting: work as a complementary of sunlight, regulate the growth of agricultural products.

Aquarium Lighting: to promote the growth of aquatic plants, also play a role of ornamental.

 

With the improvement of people’s living standards, a large number of family are equipped with ornamental tub, led aquarium lighting should be more prosperous in plant lighting market in future.

 

There are two key points in plant lighting: The choice of light wavelength and light color collocation. Most of the plant light is a combination of red light (with a wavelength of 630-640nm) and Blue light (with a wavelength of 460-470nm). Plant light can be adjustable by adding other lights (yellow, orange light). These all depends on the properties of plants.

 

According to the results given by scientist’s experiments, red ray is a mainly stimulation of plants, blue-ray’s plays a role to promote the plants bear fruits. Non-flowering plants have a large demand of red light, such as cabbage. However, cucumber, tomato and other flowering plants needs more purple light. In some places, led high bay can be treated as a substitute.

 

LEDinside survey found that Chinese manufacturers of led aquarium lighting is not enough, most of them are concentrated in Shenzhen. LED plant lighting market is concentrated in countries and regions with underdeveloped agriculture due to lack of land, such as Japan, Korea, China and the United States, Europe.

 

Compared to the traditional plants lighting technology, LED plants lighting has two main advantages:

Energy conservation: can directly produce lights needed by plants with less power consumption;

Efficient: LED emits monochromatic light, can be manufactured particular light wavelength to meet the plants need, which cannot be realized by traditional lighting products.
