Word of the LED light source luminous requirements

LED to the state and users can save a lot of energy, to save a lot of commitment to do side work. LED application technology, to the highly competitive advertising industry has added new vitality. Its unique, different light situations, is widely used in the production of advertising products field. Different specifications of the LED Bulb with different angles and different brightness. So, how to choose the right products in different LED, to maximize the effectiveness of both, but also to minimize costs? LED in light of the application and use of the word Notes solid light on the light source are the following requirements:

Shape of the complex and different items in different specifications, requirements have not shaped light limited versatility.As the installation is complete, the LED Strip Light luminous characters, very inconvenient maintenance, in order to reduce maintenance costs, require light has a longer life.Sufficient brightness for the engineering department of Nanjing Shakespeare production of the above requirements of the LED light module with the above function.

Shakespeare provides for three-dimensional light-emitting LED light source, there are two words: piranhas and small straw hat. Piranha LED module for the word wall, 8-10cm in height between the luminous words. In general,  3 and  5 LED piranha head angle of 90 degrees and 120 degrees. In this application from the next word in the plastic piranha LED Strip Light module, light emission can be completely open. Not only saves the number of modules, the screen brightness meter test, the utilization of light intensity is also just right. For the shorter word wall, word and shape of the plastic light sculpture light words, we must use light-emitting angle of 160 degrees and a small flat head piranha module LED module straw hat. Larger area of ptical radiation can reduce the amount of modules, and the lower word wall and also enhance the luminance of the font. Organically combine the two, follows the law of conservation of energy, but also reflects the importance of correct choice of LED.

The direction of LED applications

In short, the majority of the advertising industry colleagues in the use of LED application technology to produce products, in addition to considering the stability of the LED, should also be based on product requirements to determine the angle of the led down light, brightness and wavelength between the pipe and tube is allowed range. Only reasonable choice of different specifications of the LED, in order to ensure product quality standards, while the resulting costs to a minimum. The whole scene of the LED lighting system and features energy-saving and environmental protection is the world’s social problems of common concern to all countries, and directly affect the sustainable development of human society.

Not only saves the number of modules, the screen brightness meter test, the utilization of light intensity is also just right. For the shorter word wall, word and shape of the plastic light sculpture light words, we must use light-emitting angle of 160 degrees and a small flat head piranha module LED decoration lights module straw hat. Larger area of ptical radiation can reduce the amount of modules, and the lower word wall and also enhance the luminance of the font. Organically combine the two, follows the law of conservation of energy, but also reflects the importance of correct choice of LED.

Direct energy consumption of the lighting industry, hoping to achieve energy-saving green lighting. The birth of the semiconductor light source known as green lighting a revolution in the field, marked by the semiconductor light-emitting diode (LED) as a new source from the special lighting market gradually into the general lighting market, the market prospect is broad. As a special lighting applications, white LED Bulb has demonstrated significant performance advantages, the strong development momentum and rapidly growing market demand. In the next five years, LED lighting lamp is likely to become the next generation of mainstream products.

LED bonding

The purpose of LED bonding the electrode lead to the LED Bulb chip, the product inside and outside the wire to complete the connection work.Pressure welding LED packaging technology is a key link in the main process is the need to monitor the bonding gold (aluminum) wire arch shape, solder joint shape, tension.LED Test LED photoelectric parameters, test dimensions, while LED products according to customer request for sorting.

Bonding of LED technology with gold ball bonding and aluminum wire bonding two. Aluminum wire bonding process, the first LED Strip Light chip electrode in the first point on the pressure, then the corresponding frame of aluminum strands to the top, the pressure on the second point after tearing aluminum wire. Gold ball bonding process of the first point in the pressure before firing a ball, similar to the rest of the process.

LED Trim and dicing: As the LED in production are linked (not single), Lamp LED package by cutting tendons cut off the connection LED support bars. SMD-LED is on a PCB board, you need to complete the separation dicing machine work.

LED Strip Light package main bit glue, potting, molding three. Basically, the difficulty of process control is the bubbles, and more lack of material, black spots. Designed mainly for material selection, combined with a good selection of epoxy and bracket. (Usually the LED can not leak test)

The development trend of Solar lighting

As the Earth’s resources become increasingly scarce, the cost of increasing investment in basic energy rising, and a variety of safety and pollution problems can be described as ubiquitous. Solar energy as an “inexhaustible” security, environmental protection and new energy sources more and more attention. This LED Tube with the popularity of solar water heaters should be students, however, where we use solar lighting and electricity for lighting effects and practical contrast.

Comparison of the three cities have electric lighting security risks: market power due to the quality of construction lighting, landscape renovation project, materials aging, power supply not normal, water and electricity pipes and other aspects of the conflict brought a lot of security risks. Solar lighting is no security risk: is the ultra-low voltage solar lighting products, safe and reliable operation.
Other advantages of solar lighting: green, high ecological community for the development and promotion of the addition of new selling point; sustainable property management to reduce costs, reduce some of the owners share the cost of the public. Sum described contrast, LED Bulb safety without risk, no consumption of energy, environmental protection, ease of installation, maintenance and other automatic control for the inherent characteristics of real estate sales, construction of public works can be used directly to bring significant advantages

Compare one city to install complex electrical lighting: lighting project in the city has a complex operating procedures, we must first lay the cable, the cable channel will be carried out here, excavation, laying of underground pipe, pipe threading, backfill and other large infrastructure projects. Then the long installation, such as any of the lines in question, will have to rework a large area. And the requirements of complex terrain and line, the high cost of labor and ancillary materials. Easy to install solar lights: solar lighting installation, do not lay a complex line, just do a cement base, then you can use stainless steel screws.
Contrast two mains electricity lighting high: electricity lighting work with fixed high tariffs, to long-term continuous and other configurations on the line for maintenance or replacement, maintenance costs every year. Solar electricity-free lighting:led tube lights is a one-time investment, no maintenance costs, the cost of three-year payback and long-term benefit..

LED lights contrast with the traditional lamp

In recent years, more and more attention as energy saving, coupled with recent years, a substantial increase in electricity consumption, followed by maturing with  LED Strips technology, LED energy saving lamps, pro-gaze more and more people believe in not only future will replace the traditional fluorescent lamp. So what exactly is LED daylight lamp with those opposed to the traditional optimization point?

Energy savings and longer life. LED fluorescent lamp power consumption is the traditional one-third below the traditional fluorescent lamp life is 10 times, without having to replace the long-term use can reduce labor costs. More difficult to replace for the occasion.

Solid solid, long-term use, LED lamp body itself rather than using the traditional epoxy glass, more robust solid, even hit the floor LED is also not easily damaged, can safely use.

Compared with ordinary fluorescent lamps,led tube lights 18w fluorescent lamp without ballast, no starter, no strobe. Maintenance-free, frequent switching will not cause any damage. Safe and stable quality can withstand high voltage 4kv low heat can work at low temperature -30 ℃ 55 ℃. . No impact on the surrounding environment. No ultraviolet and infrared, there is no hazardous materials, such as mercury, eye protection, and no noise. Good anti-vibration, easy to transport.

But relatively speaking, more than the traditional fluorescent lamp LED Bulb has unparalleled advantages, it is not only energy efficient, “long life lamp,” said, and the applicability of the good, small size, suitable for decoration. Low-carbon environment, the quality of non-hazardous, waste can be recycled after, colorful, luminous color purity, a narrow spectral range, and the use of red, green, blue RGB trichromatic principle, under the control of the computer technology that can mix and match any different color, light color changing.

In addition, the current world to promote energy saving, LED fluorescent lamp as a new energy-saving, environmentally friendly green lighting products, will in the future will completely replace the traditional lamps.

But the LED lamp and LED lamp with an ordinary fluorescent disadvantage compared as follows: the price of your current efficiency can generally be light and there is still a theoretical light efficiency, the current life and can do real life there is a big gap between theory , but also a certain degree of heat, light failure can also be significantly reduced.

LED Tube Light

Winter to the industry is a sweeping proposition, LED Tube current in the spring, not winter, not to micro and small enterprises, represented as a standard to measure the LED industry, the season, after all, have the ability to have real technology companies, faced with LED applications, a huge market, there is still a huge space beings, these enterprises in the spring is just beginning.

LED industry is facing temporary difficulties with the U.S. financial crisis and debt crisis in Europe caused by the external environment, the poor, with the national macro-control policy, and rising raw material and labor costs, RMB appreciation and so on, but I believe that the failure of a business can not blame the external environment, because the external environment, competition is the same case at the state fair, so the final analysis, caused by internal factors.

An industry also believes that the current points-based LED Tube Light loss, in addition to the impact of regulation by real estate, there are three reasons: First, the current upstream industry chain is not cutting-edge technology in their own hands, resulting in high production costs and sales costs are high, so do not make money. The second is the people’s deep understanding of the LED, and the homogenization of the product too, nothing new, both to aid in the form of dealers to sell. 3 is not a good marketing policy into the market, largely in low-end market price, the direct collision of the enemy 1000 injury self-harm 800 is too expensive. Fourth, there is no industry standard, I heard that LED to make money, and no one to point a, have been diverted.

LED Bulb glow with the traditional lighting works differently, it has a point light source, high brightness, narrow beam output and so on. Manufacture LED lamps first thing to consider is to take full advantage of the limited flux limited exposure range, the core of conventional lighting technology with light, the real technical content or in the light of the light distribution, street lighting and tunnel lighting has proven the case this point, the LED light source with a new type of lighting designers made ​​a higher demand. Inspired by the sentiment of human life, innovation comes from the technical personnel, companies should pay attention to human resources, so people-oriented.

Led Tube company

Light-emitting diode (LED) industry event of a cold front. Lead the development of the EU into recession, coupled with the industry standard has not yet introduced, and focus on the development of Neo-Neon LED business issued profit warning, 90% LED lighting business at a loss, suggesting that the industry exists in the undercurrents. Analysis pointed out that LED products varies greatly, but with the standardization and subsidy policies have been put behind and some of the excess products will be eliminated. Led Tube is still the trend, but to replace the century-old incandescent light, a real “Myriads of Lights” is still a long way.

Despite the huge investment, but in view of technical problems, that entry is actually about 70% of companies engaged in the downstream packaging and application services, and the two parts of the total profit of about 10% to 20% of the upstream and middle reaches of the wafer and chip business profits up to 70%. Industry sources say that the high-end chips, and now more than 80% from Taiwan or overseas, the core technology at this stage is still mainly concentrated in Japan and U.S. companies.

LED lights account for 40% to 60% of the cost of the chip, the high cost of raw materials and technology, leading to the loss of price competitiveness, the main reason for not successfully enter millions of households. Power than traditional incandescent light LED 5 to 9 times, the cost of traditional lamps are often more than twice the price of natural high. It is understood, however, in recent years, the price of the chip at an annual rate of decline of about 20%. In addition, the company has recently developed a technology that will reduce the cost of nearly Qicheng LED Bulb , and another company successfully reduced the price of an ordinary LED lamp energy saving lamp level.

In addition to technical improvements, conducive to the development of policy in the “five” plan to promote the next in succession. At present, Dongguan, Huizhou, Foshan, Shenzhen, Dalian, Xiamen, Nanchang, and the development of relevant industries in succession planning. Market rumors, LED industry standards and subsidies is expected by the end of the introduction.

Some analysts pointed out that the standard in the industry before the inevitable problems are not introduced, the various manufacturers of LED Spotlight is different specifications and different ways, reportedly 50% of products on the market there is no standard inferior product.

LED Tube

Solid-state lighting, Desk Lamps, also known as incandescent, fluorescent lighting after the third generation technology, energy saving, environmental protection, safe and reliable, solid-state light source is optimistic about the industry in the next decade to replace the traditional lighting of the great potential of new light represents the future of lighting technology. Development of new solid-state lighting, lighting is not only a revolution in the field, and consistent with the current government’s “building a resource-saving and environment-friendly society” requirements.

Low-power design, 150 hours power only once, lamps provide adequate lighting in case of power as possible. Production of light using semiconductor technology has a very high photoelectric conversion efficiency, providing the power you can maximize become bright. DC power supply, effectively eliminating the additional electromagnetic loss, further reducing overall energy consumption, so that the whole power of less than 7.5w

LED Bulb widespread attention and rapid development, and it itself has the advantages are inseparable. To sum up these advantages are: high brightness, low voltage, power consumption, small size, long life, impact resistance and stable performance. Potential for the development of LED, Shanghai Xing Ma old company as an industry leader in electronics, in the early development of the industry plays a key role. At present, LED is moving higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability, full color direction.

Currently the use of LED Tube for some time, in the car lights, flashlights, etc. The application has been received well, but in street lamps and lighting have not seen many applications, this may be a bottleneck with the current technology has not yet completely break a relationship, LED although there are many advantages, but in the intensity, color temperature, and exposure range there are significant deficiencies. Such as high light intensity, but it’s not strong enough to give people the feeling of sharp glare, fluorescent light is far from sorted out than the illuminated area is too small.

THE PRICE ABOUT LED Bulb

In my mind, led wall light source with the current traditional very different, but we in the application of LED as a light source when the light is always in the old tradition to go, because we used to have the shackles of our innovative LED light source .

I can not say that he is a qualified expert of LED, but I do for most of the LED and some experts on a certain level of awareness is not high, because when they evaluate LED products are always standing tradition angle of the light source to evaluate the LED light source, so I think they are a qualified from the LED brick home.

LED Tube Light is a low-voltage cold-dot semiconductor light source, complete this sentence summarizes the characteristics of LED, and in our product development applications, which is characterized by endless, we are pursuing is the traditional light source, the required goals, which kinds of consciousness no matter right or wrong, but it is fit to the application of LED will have a certain degree of difficulty, the present situation of the integration LED light source, high voltage LED light source, I think this is the stage of product development to a certain level of semiconductor technology, cooling technology reach a certain level, I think that out of the two technologies is inevitable.

LED fatal drawback is that heat accumulated effect, within the 3 mm2 lost more than half-watt power to generate heat (since 1 watt LED electro-optical conversion rate of less than 50%), while the integrated LED exacerbated this effect more so, Even carrying a heavy thermal shell, can not completely solve the LED heat dissipation effect. LED is a point light source, so we source the design basis should be established on the basis of point light sources, on the basis of improved heat and light type of problem, our engineers are currently facing the most critical issues.

Other LED application product development as the development will still go through a tortuous process, this process is undeniable that the technology will have a short-lived (like the Chinese CVD), for experienced engineers in terms of what we have to grasp LED technology is the mainstream, great direction must not change.

I do not think the design is the LED Bulb currently on the market in this way, we can use thermal, optical principles to a consideration of the current section of the technology, learn from the optical hot, mostly not, the biggest problem is that current technology does not for standardization mode, so there is still much room for innovation.

Spoke of standardization, I would say we are counting on other people in a benchmark, our efforts this talent, this is not the correct view, the standard will give you hope and do not bring much benefit, because the standard rules of the game , you can not afford to participate in the formulation of rules of the game, not even think about how much from the rules of the game to enjoy the benefits, so the standards and specifications that are restricting someone else’s, for terms of an engineer should develop a standard to regulate their own first, and then disseminate restrict other people, you are the first “drive.” Standards is a slow process, so you should standardize their products, standardized product design processes, production processes, test specifications, and even the packaging, instructions, you can not do this, hope someone gives you a specification, you can do it?
