Indoor Outdoor Led Lights in-depth Demand Report

The economic downturn once plunged LED manufacturers into a cold winter, but since the slow economic recovery in Europe, North America and other countries in 2013, LED manufacturers have also welcomed a warm current in the industry. The industry generally believes that 2014 will usher in a new opportunity for the industry to reverse and accelerate its growth. Countries have successively promulgated bans on the use of incandescent bulbs, making 2013 the first year of LED lighting. Influenced by the recovery of the TV market and the favorable lighting industry policies, the 2014 season, which was supposed to be the off-season, ushered in the order production scale that was only available in the peak season under the condition of backlighting and lighting at the same time, the industry spring that LED manufacturers are looking forward to seems to be coming. Its cargo volume increased significantly, with a monthly growth of 11 and revenue exceeding NT $1. 2 billion, returning to the peak season level. At the same time, Wu Qinghui, chairman of Dongbei Optoelectronics, also said on February 6 that although monthly revenue has not yet been released, there is no problem in maintaining double-digit growth.

OLED lighting to the efficiency to achieve the application level of fluorescent lamp, its power efficiency must be at least 70 lm/W, although currently about 100 lm/W OLED lighting devices have been reported, but it is in very extreme cases made, usually made of the efficiency of OLED lighting devices and only 30 ~ 50 lm/W, obviously it is not up to par.
from the material point of view, to achieve such a high efficiency, luminous efficiency can reach 100% of the phosphorescent materials must be used, the green and red light phosphorescent materials have no problem, play an important role of htac is blue phosphorescent materials. Now very lack of high efficiency, high stability of the blue phosphor luminescence materials, is also the main technical difficulties of OLED lighting device efficiency, so the development and practical application of high efficiency, high stability of blue phosphor luminescence materials production technology have become the main research direction in the field.
from the device structure perspective, effective device structure design is the key to improve the efficiency of the device, at present, a lot of good device structure including light-emitting layer structure, single light emitting structure, laminated structure and the roof structure. More luminous layer structure is the preparation of white light OLED devices, one of the most mature technology, device performance is the best, but complex processes may affect its yield and production costs of OLED lighting devices in the future, and sometimes this kind of structure component is spectrum and chromaticity coordinates with the disadvantage of driving voltage changes. However, due to the good performance of the luminous layer structure, and the spectrum and chromaticity coordinates with the driving voltage change entirely can be resolved through the design of the device structure, so if you can get control on yield and improving, the structure still can yet be regarded as a kind of production technology, Philips, UDC, Novaled company is currently using this structure.
single light emitting structure to some extent, although you can avoid color purity, along with the change of the driving voltage may also simplify the process in the production process, but the efficiency and stability of the mismatching problem also make the application cannot be obtained in actual application of this structure.
laminated structure has a single light-emitting layer and the luminous layer structure, the characteristics of it is produced by electric charge layer will glow multiple unit together a device structure, laminated device has very good spectrum stability, and high luminous efficiency, high luminous intensity and good stability characteristics of laminated structure device in practical application is very competitive, if we can further improve in the aspect of the laminated structure of complex process, laminated structure device is expected to become the mainstream of lighting white OLED production technology.
top structure because of its launch in effectively and improve the efficiency of light emitting area advantages, also could become an essential part of the lighting white OLED technology development direction, and combine other structure and top emission structure can develop higher performance of white light OLED.

Don't know since when, LCD TV series TV jiangshan gradually, the past stores in various TV scenes of flowers is not to see. But if you think choose TV now will be less, that would be wrong. The concepts of the television but now is less than before, what 4 color 4 k, quantum dots, various new concepts emerge in endlessly. But the most troubling, is TV of all kinds of LED the concept of 'X'. Not only appearance is similar, and the description of the merchant is also unfathomable, let ordinary consumers. Today small make up together with you the true, detailed tell me the differences between various kinds of 'X' LED before.


LED LED TV celebrity believe all consumers want to buy TV should be very familiar with, now on the market most belong to the LED TV. The full name of LED Light - Emitting Diode, look very tall, English translation is actually the light Emitting Diode.
may ask some friends, LED TV LCD TV, isn't it, how to become the light emitting diode?
don't know if you remember a few years ago the 'LCD TV', actually is the representative of LCD LCD TV ( 液晶显示器) And LED TV, refers to the liquid crystal panel as the display medium, using light-emitting diodes as a backlight module of the TV. Now LED TV is LCD TV, and 'LCD TV' in the past, actually should be called CCFL television ( Cold cathode fluorescent lamp ( 冷阴极荧光灯) ) , as to the name of LCD TV, can only say that manufacturers and merchants a misrepresentation.

actually refers to the TV backlight LED TV is composed of LED lamp bead
ULED
ULED is hisense TV carry a display technology. Strictly speaking, the ULED actually is not a technique, but hisense TV carry all kinds of LED display technology integration and implementation effect. In addition to the more general picture of optimizing the parameters of brightness, color, ULED is representative of a kind of technology is a partition point light.

ULED has become the symbol of hisense high-end TV
due to the LCD panel will only color don't shine, so the LCD TV is illuminated by a backlight module. And ordinary liquid crystal TV can open and close at the same time a whole screen backlight, which creates a LCD TV on the display when the dark is not completely black. And zoning control the backlight is divided into N partition alone, to control the backlight through intelligent recognition image, open bright, dark place closed, achieve better image quality.

dynamic backlight can identify the image content to control the backlight
it is important to note the partition point light not ULED unique technology. ULED TV must have a partition control light ability, but with the function of partition control light TV is not necessarily the ULED TV. Coordinating editor CQJ

Respects at the end of 2018, the National Energy Administration, seeking to strengthen the implementation of the standardization work on alternative energy storage technology. And according to the plan, the establishment of energy storage technology standard systematic coordination mechanism. Our country's economic development has made remarkable achievements,




at the end of 2018, the National Energy Administration 【 The National Energy Administration ( 国家能源局) Was established in 2008, the deputy ministry units directly under the National Development and Reform Commission, agency for integrated, policies and regulations, development planning, energy conservation and technology equipment, electric power, coal, oil, natural gas, new energy and renewable energy, international cooperation department nine department, 112 people. 】 Sent a letter seeking to strengthen the implementation of the standardization work on alternative energy storage technology. And according to the plan, the establishment of energy storage technology standard systematic coordination mechanism.


our country's economic development has made remarkable achievements, but the current energy situation is still not optimistic. Vulgar way while promoted the development of the economy, create the wealth for the society, but the problem of also nots allow to ignore, especially energy situation is particularly serious. In general can be summarized as the following three points.


( 1) Although energy is abundant in our country, but is also a country with a large population in our country. Abundant supply per capita scarce became a distinct characteristic of our country's energy reserves.


( 2) Our energy distribution is not balanced. The general area rich in energy is not economically developed areas, while the total amount of the southeast coastal developed areas such as energy is much less. A similar 'west-east gas 'West to east gas pipeline, the longest diameter of the largest in the pipeline, west lunnan area of tarim basin, east to Shanghai. 】 'Project officially in order to solve the problem of energy distribution in our country.


( 3) The current energy structure is given priority to with coal still have large pressure on the environment. Our country still is given priority to with coal energy structure's impact on the environment is obvious, is not conducive to the sustainable development of China's economic and social goals.


energy based on the above situation, research and development of new energy and energy efficiency, has become the chief problem of the energy industry must solve. For such energy giants in China, both energy conservation and emissions reduction, also need enough energy to meet the development needs, the importance of energy storage industry increasingly apparent. Vision of the National Energy Administration, energy storage technology standardization work began. The move will be landmark spanning energy development in our country, and will promote the healthy and orderly development of energy industry in China is more norms.


however, like solar and wind energy, can be instability, so the energy storage technology is very important. In order to solve this technical weaknesses, lighting provide a higher quality of solar street light products for the society. Developed lithium electricity intelligent control system. This system equipped with optimization of intelligent management system, real-time monitoring and protection of lithium battery charge and discharge voltage, current and monomer can be perfect match all kinds of solar street light. The development and utilization of new energy is the development trend of the energy industry, the standardization of energy storage technology will provide good for development of energy industry in our country political system environment. Lighting will actively response to the energy storage technology standardization work, contributing to the healthy development of the solar street light industry. Lighting is willing to work with you together to sow the light, let the sun shining in the dark.

LEDinside's new LED bulb retail price survey shows that this year (2015) In April, the average retail price of LED bulbs replacing 40W was about 1. The decline of 0 reached 11. $8; The average price of LED bulbs replacing 60W is 0. 1 decline, the price remains unchanged, still 15. $9. The price decline in Europe and the United States is more obvious, especially in the UK; Prices in the Asian region have been reversed, especially in mainland China. Low-priced inferior products have gradually withdrawn from the market, resulting in a rebound in overall prices in the short term. Replace the 40W part, the UK region, following the March price is 4. After the decline of 7, April continued to show 4. A drop of 6. Some products with rising prices in the previous period have been returned this month. For example, Osram6W470lm bulb lamp, the price dropped to 8. 07 US dollars, a drop of 35; Auraglow7W480lm bulb lamp, the price dropped to 6. $2, a drop of nearly 30%. Others such as Toshiba7. 5W470lm, Philips6W470lm bulb lamp, the price drop is also large. Prices in Germany have maintained a downward trend since entering 4Q14, but the decline has slowed down, with prices falling by 2. 5% in April. 1. The prices of some well-known brands such as Samsung, Toshiba and Osram have been lowered. In Asia, prices in Taiwan fell by 5. 5% in April. 9, some merchants take promotional measures, pull down the overall market price, such as Zhen Mingli 8W450lm bulb lamp, the price fell to 3. 04 US dollars, a drop of more than 50%. In mainland China, prices rose by 4. 5% in April. 1. Prices have risen for the first time since 2015. Some low-priced products have withdrawn from the market, while others have increased their prices. For example, the price of sanxiong Aurora 5W500lm bulb lamp has increased by 6. 5%. 55 to 2. 47 dollars. Price fluctuations in the rest of the region are not large, and exchange rate is the main factor in price fluctuations. The retail price of LED bulb lamps replaced the 60W part, and the UK showed a 6-year decline in April, which was the region with a large decline. The prices of most products have been lowered, and the prices of a small number of products have dropped significantly. Such as Philips9. 5W806lm bulb lamp, the price dropped to 6. 2 US dollars, a drop of 38; Osram10W806lm bulb lamp, down 25 to 11. $18. Prices in Germany fell by 2. 6. The price fluctuation of most products is small. Prices in the United States fell by 2. 8. Prices of some products fluctuate greatly, including Philips, Osram and other brands. The price increase in mainland China was 1. 1. The withdrawal of low-price products from the market is the main reason for the increase in average prices. Prices in the rest of the region remained stable. Low-priced and inferior products were delisted. In April, the price of bulb lamps in mainland China increased in a short period of time. Mainland Chinese manufacturers have always occupied the market with low prices, so the quality is difficult to guarantee. With the development of the industry, low-priced inferior products are gradually being abandoned by the market. The industry reshuffle continued, and small manufacturers gradually withdrew from the market. However, in the long run, the short-term price reversal is only a response to the market demand for products at this stage, and prices will continue to decline. however, the reason for the decline will gradually shift from market competition to technology competition.
