led moving light in the stage application

LED Strip depends on the quality and attitude of manufacturers have equipment capacity. To produce high quality LED flexible strip must be to improve the management methods and reliable to do to ensure incoming inspection process, using high-precision positioning of the LED SMD placement machine, and then through the wave soldering, welding can be carried out after a good PCB test separator, connecting, testing, aging, plastic closures, aging, packaging and finished products. Step will affect every aspect of LED flexible strip performance and stability, workshop-style hand soldering and packaging out of the soft light strip is not in the anti-static workshop with precision LED SMT package with clean out high quality LED flexible strip of the same led moving light language.

One, LED lights Chip
Is a set of LED industry chain, which is in the upper reaches of the chip wafer cutting and production, which is currently the LED industry’s most technical content of a link. Epitaxial wafers mainly from Japan, Korea, Germany provided, mainland enterprises in Taiwan chip, its epitaxial wafers mainly from Japan and South Korea, the brightness, the light fades is best made in Japan, Taiwan, Guang Jia, the United States and other epitaxial Puri tablets from Japan, which provides chip reputation in the industry are better. Currently, Japan provide external epitaxial crystal factory outside except that it has to start their own cutting, which are bound to Taiwan and the mainland fab pressure. Part of the package, mainly in Taiwan and mainland China, including Taiwan enterprises in the package is a world leader appeared Everlight, Bai Hong, East Bay, a large number of high-quality corporate CMO. After the year 2000 with the blue chips and white craft after another, as well as mobile phones, backlight, lighting and other applications market expansion, ushered in the industrial packaging companies in Taiwan spring.

    Second, LED light package
To encapsulate the form, from the initial line 3MM, 5MM, 8MM, 10MM, piranhas. SMD 0805,0603,1206 later development, and now the 1210 (3528), 5050, etc. TOPLED series. So LED strip is developed from the common line to 0805 and 0603,1206, and now the market is the most fiery 5050 series products. It is noteworthy that the brightness of led moving light has a direct correlation with the wafer. Currently chip package has 9MIL, 12MIL, 14MIL and other dimensions, in theory the larger wafers, higher power and brightness, of course, the price is more expensive, the current market many companies employ 5,050 package appearance, but actually using the brightness relatively low small chip, thus resulting in low prices, but the quality is not good, this is the customer irresponsible. When used to carefully identify lamp beads and brightness of the welding process, during which different instruments can be quickly identified.

    Three, LED light bar package
LED light bar is divided Flexible LED strips and LED light bar two, the differences are as follows:

    1, Flexible LED Strip is done using FPC circuit board assembly to be assembled with SMD LED, the thickness of the product is only a 1MM thickness, does not occupy space; common specifications per meter 30 lights, 48 ​​lights, 60 lights, Different users have different specifications. And it can cut, it can be any extension of luminous unaffected. FPC material is soft and can be bent, folded, winding, can freely move in three-dimensional space and stretch without breaking. Suitable for irregular local and cramped places, but also because you can arbitrarily curved and winding, suitable for use in advertising in any combination of a variety of decorative patterns. FPC itself is worthy of prompt material is also a variety of points, with the formal market above is made of rolled copper dual panel FPC, of ​​course, many enterprises are also blind pursuit of material costs down, take electrolyte made of FPC, FPC electrolyte easy to peel off during welding, Weld, and a direct result of the phenomenon of dead lights, in addition to whether it is from the electrolyte conductivity and flexibility are unable to compete with the rolled copper.

led moving light in the stage application
2, led moving light bar is made with hard board PCB circuit board assembly, LED SMD LED useful to be assembled, but also useful for assembly-line LED, depending on the different needs of different components. The advantage of rigid strip is relatively easy to fix, processing and installation are relatively easy; shortcomings can not be bent, not suitable for irregular areas. Rigid Strip with SMD LED per meter 30 lights, 48 ​​lights 60 lights, a good variety of specifications; using DIP LED’s are 18, 24, 36, 48 different specifications, there is also a positive side, the side also known as the Great Wall lights glowing.

From the large side, LED bulbs necrosis of the reasons is nothing less than the following two:
First, the leakage current of the LED is too large resulting in failure of the PN junction, the LED light does not shine, this case will not affect the work of other LED lights;
Second, the internal connection to the LED lamp lead is disconnected, causing the LED current through the dead light, this situation will affect the normal work of other LED lights, is due to the low operating voltage of the led light prices (red, yellow, orange LED operating voltage 1.8V-2.2V, blue, green and white LED Operating Voltage 2.8-3.2V), are generally required in series or parallel connection, to adapt to different working voltage, the more the greater the impact of the series of LED lights, which has an LED lights internal wiring open circuit, will result in the series circuit of a whole string of LED does not light, this case can be seen to be more serious than the first case. The dead LED lights that affect product quality, reliability of the key, how to reduce and eliminate the dead lights, improve product quality and reliability, packaging, application companies need to address the key issues. The following are some of the reasons for dead lights Some analysts explore. Next on the detailed interpretation:

 

led light prices in 2013

Electrostatic damage to the LED chip, led light prices chip of the PN junction failure, leakage current increases, becomes a resistor electrostatic hazards greatly around the world because countless electrostatic damage electronic components, resulting in tens of millions of dollars economic losses. To prevent electrostatic damage to electronic components, the electronics industry is a very important work, the LED package enterprise applications do not take it lightly. A part of any problems, will cause damage to the led light prices , the LED performance deterioration or even failure. We know that the human body static electricity (ESD) can reach about 3 kV, enough damage to the LED chip breakdown in LED packaging production line, the grounding resistance meets the requirements of various types of equipment, which is very important, general requirements for the grounding resistance ohms, even some high occasions the grounding resistance ≤ 2 ohms. These requirements are familiar to the people of the electronics industry, the key is in the actual implementation is in place, whether recorded. It is understood that a general private enterprises, anti-static measures has not been in place, this is the most businesses can not find out the grounding resistance test records, even if the ground resistance testing once a year or a few years time, or there is a problem check the grounding resistance, not knowing that the testing of ground resistance This is a very important work, at least four times a year (quarterly test), some of the requirements of a high place, a month will have to use a grounding resistance test. Soil resistivity changes with the seasons, spring and summer days of rain, the soil wet ground resistance is easier to achieve, autumn and winter dry soil moisture, grounding resistance is likely to exceed the specified value, the record in order to preserve the original information, do to future well documented. In line with the ISO2000 quality control system.

 

Old house renovation stimulating demand for led lighting effects

In order to further curb housing prices, crack down on property speculation action. On the night of March 1, the State Council officially announced the five countries “implementation details of the real estate regulation.

Be worry about the implementation of the five countries “to bring the rising cost of housing resale, the second-hand housing market first react. A lot of second-hand housing homeowners who are eager to cash out the hands of properties for sale. According to the Shenzhen Centaline the monitoring, the week of February 25-March 1, the Shenzhen second-hand housing turnover increased by 40%, 1517 sets of transactions, closing an area of ​​123,000 square meters.

Old house renovation stimulating demand for led lighting effects

Old house renovation stimulating demand for LED

The report said GLII 2012 mainland China LED indoor lighting production value is 335 billion yuan, an increase of 80%, but the growth points mainly from the field of business according to the home lighting market potential yet to be developed. Despite the lack of knowledge of the ordinary consumers of LED lighting, but in recent years, LED frequent media exposure, coupled with the declining market for LED technology touted and product prices, consumer’s led lighting effects tentative purchase psychology even more strongly.

The survey shows that 80% of families Lighting purchase is accounting for more than 10% of the total cost of renovation of the housing, in which a small number of household lighting consumpt of 3,000 yuan, most of the family is as high as 5,000 yuan.

In addition, along with the improvement of second-hand housing renovation upgrading, compared to traditional lighting highlights, the technical highlights in LED help housing interior upgrade innovation.

Improvement of second-hand housing decoration demand for LED lighting is a very good opportunity to led lighting effects. Upgrading from the original traditional home lighting to meet the psychological needs of the housing. An interior designer said, local second-hand housing tends to upgrade local decorate, with relatively little cost, so the homeowners are easy to accept.

But others took a different view. Xu Liang in Yazhi decorated told reporters: at present, the second-hand housing market is so popular, to a large extent, the seller just want to avoid the 20% transaction tax.

The popularity in led lights for the home

Shenzhen Xianglong photoelectric Blue Wen-liang told reporters: “If a family is fully configurable LED home lighting, th cost is about 5,000 yuan to 6,000 yuan, the price is high but still affordable for consumers. But lacking of knowledge of the LED is still a long-standing problem, so it leads the LED in the field of household consumption and the effects are poor. ”

But he also explained that with the rise of the young consumer groups, the LED user groups will become an increasingly widespread

The popularity in led lights for the home

The led lights for the home will be a new house “standard”

With the five countries, second-hand housing transactions in Beijing, Shanghai, Guangzhou, Shenzhen and other places gradually are cooling down, the opposite is the new home sales gradually benefit from it.

Fearing 20% of the transactions taxes increase the cost of home buyers will have more to choose a new home may bring new home prices rose too fast.

Accordingly, the official said, for the problem of rising house prices, the developers need to develop a new bright spot to reflect the selling point of the real estate, and smart & intelligent home furnishing can constitute an important selling point, as property sales gimmick.

Industry experts point out that, intelligent lighting control system uses a modular design, the dimming module, switch power, scene control panel, sensors and programming, the programming socket, PC monitoring machine independent control module is connected to the computer data line, composed of an independent lighting control system, intelligent management and automatic control of lighting systems.

Compared to other traditional light sources, LED intelligent lighting system showed better compatibility and interoperability, and have a greater advantage in energy efficiency. Intelligent LED lighting will become the new trend of the future development of lighting technology.

In the United States, the intelligent LED lighting has been reached first in the proportion of intelligent home industry. The LED Engineering Institute (GLII) statistics, the domestic intelligent led lights for the home penetration rate is less than 2%, the relevant market is still in its infancy, a far distance from the United States and other developed countries.

“To sell the concept of intelligent LED lighting to high-end residential users, it is a relatively new marketing tool, there are relatively few people do, but the market is still there, the key is to look at how to cut into consumer psychology.” XuLiang told the reporter.

stage lighting led with CREE Chips

In order to fulfill the US Energy Independenceand Security Act and the EU eco-design directive, the artificial lighting system transition from incandescent to energy-saving lamps (CFL) and LED, in order to save energy and reduce greenhouse gas emissions. Compared with the traditional incandescent bulbs, the new energy-saving lamps and light-emitting diode (LED) bulbs stage lighting led can save 70 to 85% of energy consumption, service life is also greatly increased, and therefore is considered to be a huge energy saving potential The technology, however, the design of these new bulbs than traditional light bulbs is much more complex, with potential adverse environmental effects, even with consumer electronics devices. CFL and LED components containing more metal. Uncertainty of the potential environmental impacts of these components is necessary to dispose reached the end of its working life, the need to make special provisions? Seong-RinLim published an article published this month, “Environmental Science and Technology” (Environ.Sci.Technol) LED potential environmental impact: metal resources, or toxic hazardous waste (PotentialEnvironmentalImpactsofLight- EmittingDiodes (LEDs): MetallicResources, Toxicity, andHazardousWasteClassification). Their three types of bulbs (incandescent, LED  stage lighting led and energy-saving lamps) in many aspects of the evaluation of the environment and resources.

stage lighting led with CREE Chips

After the test found that LED bulbs need to be gold, silver, antimony, copper, and so on resource consumption than incandescent two orders of magnitude, 2-5 times higher than the energy-saving lamps. Have a major impact on resource consumption for energy-saving lamps, material is copper. Silver and gold is a precious metal as a material resource crisis in the EU antimony. Copper in the United States has not yet reached crisis proportions, but in the energy saving lamp and LED, the amount of copper is very high, other metallic materials is 1-6 orders of magnitude, to develop also worrying. Most metal content in the LED lamp is aluminum, barium, chromium, gallium, and they will be obvious to result in the total consumption of resources. To note here is that on in Supplier consideration risk Although gallium reserves in the world is estimated to be quite large, it is still considered a possible crisis of material, because gallium only be obtained as a byproduct of the processing of bauxite and zinc ore . On the contrary, yttrium, gadolinium and cerium also belong to the rare earth elements, but less likely to become a crisis material, yttrium, cerium fairly abundant, the amount of gadolinium very little.

If the LED and energy-saving lamps at the current rate continues to replace incandescent bulbs, will have a considerable resource consumption, because the supply of gold, silver, antimony, copper resources are insufficient. As having a low electric resistance is mainly used for connecting the LED chip electrode wire. Silver as the stage lighting led in excellent reflective coating material. Antimony is a core material of the LED chip. Copper is used for the LED and energy-saving lamp coil and the printed circuit board. DfE these auxiliary components (non-light-emitting technology itself) there is hope for transformation and modernization in order to reduce the metal content, as in the information and communications industry, fiber-optic cable instead of copper cable. Additional examples of successful DfE actual product can be found in the U.S. EPADfE website. In addition to the transformation of the component technologies, recycling technologies and management strategies should follow up to ensure the recovery of precious metals in the LED and energy-saving lamps can be recycled.

Regulations of existing U.S. federal and California state government, through the application life cycle impact and hazard-based evaluation methods to assess whether these bulbs products to be classified as hazardous waste. Life cycle impact-based approach, with the conventional life cycle assessment (LCA) is different, it is to quantify the toxicity potential of LCA elements. The energy-saving lamp and the LED lights are to be classified as hazardous waste, because the loss of lead (132mg / L, 44mg / L, respectively, has been extremely excessive prescribed safety standards) and a high content of copper (111000mg/kg, and 31600mg/kg, and safety standards for 2500), Lead (CFL bulbs 3860mg/kg safety standards for 1000) and zinc (CFL bulbs 34500mg/kg safety standards for 5000), and the incandescent light bulb is not dangerous the. Note that results CFL lamp bulb mercury vapor is not considered, the experimental sample preparation process does not capture). Compared with incandescent lamps, energy saving lamps and LED lamps have a high potential to lead to resource depletion and toxicity, mainly due to their high aluminum, copper, gold, lead, silver and zinc.

Shenzhen brakes play a vigilant role in professional led lighting

One side is China’s LED industry is lack of core technology, the other side is supported by the state LED among the strategic emerging industries; one sideis that LED products price drop of 35% for two consecutive years, the other side is  that LED Industrial Park across the country has built more than one hundred, its production capacity is gradually increasing.

At the end of last year, the newspaper published a “force to promote professional led lighting products is alleged to lead the industry disaster”, an earlier warning of the plight of the industry.

Shenzhen brakes play a vigilant role in professional led lighting

Recently, the Shenzhen municipal government quietly abolished the form of the “Official Gazette” March 2009 introduction of the “Shenzhen LED Industry Development Plan (2009-2015) on the issuance of the notice, the wind industry mutations. Turn Left or right? LED industry enter into a crossroads.

Shenzhen brakes play a vigilant role

Shenzhen’s policy change does not stop the other area’s fantastic to LED

Recently, professional led lighting forum in the northern city of Changchun, Changchun High-tech Zone and the Illuminating Engineering Society of Jilin Province jointly issued a written proposal of a province-wide accelerated to promote the use of efficient lighting products, LED energy-saving “Changchun High-tech Zone to build one hundred billion LED industry base planning debut at the same time.

Shenzhen Confucianism Electronics Co., Ltd. is a large LED NVC enterprises suppliers. According to the people in Confucianism electronic said: “we do not feel the policy adjustment have any effect on the Shenzhen Shenzhen Confucianism. Instead, corporate orders piling up, right not, they do not let the salesman go out to accept orders.”

Another  investment management Mr. Tang said to a newspaper reporter, his understanding of the Shenzhen LED enterprise products for Eastern Europe and other international markets, at present, do not see affected in any capacity.

Industry forecast, LED industrial structure of overcapacity situation will continue in 2013.

Industry experts said in an interview with a newspaper reporter, Shenzhen halt LED industry planning vigilant role in this industry, local governments still continue to blindly launch. Its loss may be incalculable.

The color lighting Game between the government and enterprises

“In fact, this is the game between government and enterprises.” Used to hold different views, Guangdong Province, vigorously promote LED color lighting, and a letter to the Science and Technology Department of Guangdong Province, Guangzhou color lighting industry professionals Hu Jun, in the “China Business” reporter interview, said: “the local government should build land finance, with the establishment of high-tech park to attract business investment to pull the GDP like LED fancy high-tech subsidies and vigorously promote government executive order market.

The color lighting Game between the government and enterprises

Government established industrial park, it was because the industry is defined as high-tech industries, the government hopes to bring more tax revenue, it will give a certain amount of subsidy, this industry will become bigger and stronger, in order to create hundreds of billions of tens of thousands of million companies. “Hu Jun” China Enterprise News “reporter provides a data: after several years of fostering, LED enterprises in Shenzhen is only output value amounting to billions of dollars, but if the Government determine the development of the Internet or biological emerging strategic industries, just a project over $ 100 billion this industry, facing land resources are so scarce in Shenzhen, the government is clearly to give up. ”

“I have seen LED Industrial Park, the scene was tattered but brand stand up, and then you can go to the mortgage.” Hu Jun, “China Enterprise News” reporter he had ever seen a LED color lighting Industrial Park,”Most are to hit the ground, put forward a plant, and then lie to the government subsidies. Now the government is not so easy to cheat, usually if you do not do, I have not been replaced, the government is now very sensible.”

However, the Science and Technology Department of Guangdong Province, Shenzhen approach does not seem to fully agree with. “China Enterprise News” reporter a telephone interview with the Director of the Office of Science and Technology Department of Guangdong Province, Lin Xiaoyong, he said, the Guangdong Provincial Science and Technology Department is not clear Shenzhen halt led dimmable light bulb industry planning, no matter for whatever reason, Guangdong Province will still insist vigorous support to the industry.

led theater lights in China

led strip light color pure, brilliant color, high brightness, energy saving, long life, safe and reliable, and gradually cut a striking figure in the decoration industry. Led light bar is the launch of new products in recent years, some customers did not come into contact with, it is unclear for how to install.
led light bar used for interior decoration, waterproof, UV less demanding, installation is relatively simple. Shang Mingguang electricity production of LED light bar, for example, each LED theater lights flexible strip behind affixed with self-adhesive 3M double sided tape, installation torn 3M double-sided adhesive sticker on the surface, then the LED light strip is fixed at installation location, hand snapping like it. As for some places need to bend or LED light strip length is inconsistent. LED strip is composed of three LED for a group of series and parallel circuit structure, that can be cut every 3 LEDs can cut short can be welded up.
LED Stage Lights strip for outdoor due to be affected by rain, ultraviolet erosion, 3M adhesive fixed a long time will result in a decrease in the 3M adhesive LED strip off, so the installation of outdoor LED theater lights  flexible strip is often used slot in a fixed manner. Need to be cut and connected, and indoor installation, just need another with waterproof glue to strengthen the connection point of the waterproof effect.

led theater lights in China
LED strip General voltage is DC 12V, and therefore requires the use of switching power supply, the size of the power supply according to the power and length of the LED light bar. Can also buy a power switching power supply for total power, all LED flexible strip all the input power in parallel (wire size is not enough, then you can otherwise extended), unified by the total switching power supply. The advantage is that centralized control the inconvenient places lighting effect can not be achieved single LED theater lights bar and switch control, specific to the manner in which you can have to measure.
Happy LED strips and RGB strips need to use the controller to achieve a color-changing effects and control the distance of each controller is not the same, general, simple control of the controller a distance of 10-15 meters, control the distance of the remote controller 15-20 m, can control up to a distance of 30 meters. If the connection distance is longer, the controller can not control so long LED strip light bar, then you need to use the power amplifier to tap.
LED light strip on the distance of the connection. 3528 SMD series LED strip connect it to the maximum distance of 20 meters, and 5050 series LED light bar, maximum connection distance of 15 meters. If the connection distance is exceeded, the LED strip is easy to heat, the use of the process will affect the service life of the LED light strip. Therefore, the time of installation must be installed in accordance with the requirements of manufacturers of LED light bar, should not overload operation.
When install LED light bar, to consider the following questions: waterproof rating, total power, power supply, controller.
