a fear that heat will not be solved;


market on electricity for lighting circuits, is not very mature, well short of the level of traditional lighting. Efficient light sources need to support efficient drive line. Personally, I think efficient driving route to more than 90% must be attained. If the stress isolation security,led candle light, obviously can not do it efficiently. Do not isolate the traditional lighting with high efficiency, LED must be the same. We feel unsafe LED cooling mainly due to more use of aluminum radiator, it is evident in the design of products need to change ways of thinking!

IC design, LED lighting market is an emerging industry, there is no reference to circuit design, the majority of IC design enterprises do not know their own minds,led furniture lights, often by too many \To good design, vertical and horizontal products can be compatible, and finally all the \

most interesting IC-AMC7169, a ratio of output with LED IC, we design 100pcsLED lamps to be used 100pcsAMC7169, it is not protected IC, short-circuit voltage increased and then decreased current look Daoshi Some destructive! Design product problems, first of all is to how to solve, how to avoid, rather than setting a large number of patches. Use this line, the line itself on its own had no confidence in it has to do! Personally think that the most deviation in LED design direction of an IC.

electricity most in need of LED lighting design problem is how to adapt to different load voltage and LED current changes; mains voltage fluctuations ; heat conduction and isolation safety; efficiency costs. Previous 1: LED lighting in the home market prospects

the formation of the market needs some rules, too outrageous publicity will affect the entire industry, a long time will bring to their business to negative effects, damaging its own reputation and interests. LED light conversion efficiency and energy saving lamps is basically the same, how can design energy-efficient than traditional lighting products too! Basic concept, being promoted to be recycled several power plants out of the gorge. Almost would say no energy shortage is a result of the timely application of the LED. Generally used to publicity,led bulb, said that the use of LED lighting industry are what if? The world are using what? Actual diversity of the world might like this?

Strictly speaking this stage \not to mention energy efficiency, energy conservation is the future. Instead of saving at this stage also consume large amounts of aluminum.

such as lamps, design power at 100W or so, why did he choose this power? Also mentioned earlier is the cost considerations, the basic brightness can reach the national standard needs, LED prices should be reduced as much as possible, allowing customers to accept. Some users take 100WLED 250W sodium lamps with energy saving ratio, but also to use national standards as a reference, the brightness of the 250W does not explain the excess, this fair? 100W HPS in turn we can not meet the national standards designed street lamps. This and the current Government has stressed several times increase in energy-saving air-conditioning temperature What is the difference?

radicals, mainly, production LED lighting and LED-based production company producing packaging business. Of course, understandable, and we are standing position of the general relationship between the ranks have. Usually put their arm on the first slow-moving products themselves, demonstrate their contribution to the energy.

usually in election publicity is publicity of environmental protection targets, but these do not have enough reason to replace the existing lamps, the next most powerful trump card, or energy, but the price is a decisive factor. LED lighting in the current market is not the result we expect, the cost is the biggest factor.

current driver line Status:

caution into the emerging industry is normal, but excessive worry about their own intuition alone assume market outcomes, will miss the opportunity. Understanding by the market point of view, conservative thinking on the LED lighting the main reasons are the following aspects:


LED lighting conservatives

LED is no clear documentation to follow, will not affect the LED process. Many products are not the appropriate standard, not all developing well and be proud! LED there is no standard to follow, LED Christmas lights are not used non-isolated for many years it! Some friends always take a conservative attitude towards LED development process. The existing street lamps, energy saving lamps (including fluorescent), lighting is non-isolated, not sure some friends Why must we separate LED products? I think that is a typical conservative mentality.

look at the lighting fixtures are not before the isolation, most of the adapter and the need for personnel to access electronic products, LED lighting is clearly such a requirement is not justified. LED power supply and current-voltage switching power supply products in the regulatory aspects of safety will not be much difference between the safety requirements applicable to LED products, just different light sources, there is no essential difference. Even if the newly issued regulations for LED security, it must be conducive to the future direction of LED, will not happen limitations.

3, were concerned about the short life of electrolytic capacitors affect the LED process;

heat mainly to see the way we design, is not no way to solve the real problem is cost. LED lighting in the design of long-standing use of lamp (light source) affect the structure of the concept, there is always that difficult to solve high heat. No indication that the bulb can only design as widely used in the lighting market, we should discard the existing traditional concept, to have breakthrough ideas and development.

such as LED lights to take the existing terms, why should the design of 100W or so, why not with the same high-pressure sodium lamp 250W? Is clearly the cost considerations, LED design 250W, LED costs and cooling costs much higher, making the cost of the market can not accept. Not so high power is not designed, nor heat can not solve. At this stage as long as acceptable areas LED prices are good applications, and not subject to the limitations of cooling conditions can not be used LED. Cooling is difficult, the path of development in the LED is that we need to address, and cooling is a cost , not to solve the problem.

temperature, typically many requests for LED products within the surface temperature of 50 ℃, this attitude is wrong. We used to look at specific environmental conditions, in many settings can not guarantee the temperature 25 ℃, 50 ℃ to achieve the product surface is obviously difficult. LED products in the design of most need to consider the LED junction temperature. If the surface temperature is low, the heat does not shed, junction temperature exceeds the reasonable value, it is clear that product design is a failure! Conversely, LED product design, a small thermal resistance, junction temperature is kept within reasonable limits, product case temperature reached 80 ℃, it was no good. Not good touch on the judge failed, hot products is determined not good. How many people dare to touch the existing appearance of the traditional lamp, burning feeling experience, it is clear that LED lighting products required temperature is a personal attitude problem.

two, worried Safety issues;

LED development can draw on, \Moore (GordonMoore) to prepare a computer memory trends on the report. He compiled a observations. He began drawing at the data, found a surprising trend. Each new chip contained roughly twice the capacity of its predecessor, the production of each chip is a chip production after the first 18-24 months. If this trend continues, computing power compared to the time period will show a rise exponentially. Moore's observations, that is, the so-called Moore's Law, which set the trend has continued since, and still unusually accurate.

to improve in terms of brightness values is obviously no way to double in 18-24 months, but the price drop and the growth of integrated intensity for 18-14 than doubled.

LED lighting radicals:

we can not take life electrolytic capacitors determine the LED product life, the theoretical value and actual value of phase wrong far, publicity has 100,000 hours LED life, the value of this theory is difficult to be confirmed. Electrolytic capacitors widely used in existing light, do not see that there is such serious consequences. Electronics can not guarantee 100% no damage, LED products is the same life expectancy lags behind other devices LED devices, the market will force the update or new device electrolytic capacitor was born. LED lighting does not affect the development process, it is unnecessary worry.

4, the price is too high can a large number of applications;
