LED lighting: a debate between conservatives and radicals

LED lighting conservative emerging industry caution is normal, but excessive worry, intuitively assume the results of your market, you will miss the chance. The understanding of the market, the following aspects of the main reason why LED lighting conservative ideas: first, worry about radiation is not very good solve the heat mainly depends on the way we design, not without a solution, but also the actual cost. In the design of LED lamps by long-term use of light bulbs (point light) structure concept, the total heat transfer is difficult to solve. There is no indication that only the design can be widely used in the lighting market, such as light bulbs, we should put aside the existing traditional concepts, to have a breakthrough idea and development. For example, with the current LED street, why about 100W, why not and HPSL like 250W? Apparently cost considerations, LED design 250W, LED cost and heat cost will be much higher, so the cost to let the market can not accept. Design is not so much power, nor heat can not solve. At this stage, as long as the price acceptable to the field of LED, the application is better, and has not been limited by the conditions of heat dissipation can not be used LED. Heat is difficult, in the development of LED is the way we need to solve the problem is the cost of heat is not able to solve the problem. Temperature, usually require a lot of LED product surface temperature of 50 degrees Celsius, this mentality is wrong. Depends on our specific use of environmental conditions, in a lot of environmental temperature can not be guaranteed at 25 degrees C, to achieve the product surface of 50 degrees is obviously difficult. LED junction temperature is the most important consideration in the design of LED products. If the surface temperature is low, the heat is not dissipated, the junction temperature exceeds the reasonable value, obviously this product design is a failure! In turn, thermal resistance of the LED product design is very small and the junction temperature is maintained in a reasonable range, the shell temperature reached 80 degrees, it's not what good. Can not touch the judge to determine the unqualified, hot products on the bad judgment. How many people dare to touch the existing traditional lamp appearance, experience burn feeling, it is clear that the requirements of the LED lamp product temperature is a personal mentality. Two, worried about security issues LED no clear documents to follow, will not affect the LED process. Many products do not have the corresponding standards, do not have a good development! LED no standard to follow, LED Christmas lights are not isolated is not used for many years, some users always take a conservative view of the development process of led. Existing street lamps, energy-saving lamps (including fluorescent lamps), spotlights are non isolated, not sure why some friends must be LED product isolation I think is a typical conservative mentality. Throughout the previous lighting are not isolated, isolation and most of the operators are required to contact the operator of electronic products, it is clear that the requirements of LED lighting is unreasonable. LED power supply and the current voltage switching power supply products in terms of safety regulations will not be much difference, the security requirements for LED products, but the light source is different, there is no essential difference. Even if the introduction of new LED security requirements, it must be conducive to the future direction of development of LED, there is no restriction. Three, concerned about the use of electrolytic capacitor short life we can't affect the process of LED electrolytic capacitor life determination LED product life, the theoretical value and actual value is wrong very far, propaganda LED life of 100 thousand hours, the theoretical value is difficult to be confirmed. Electrolytic capacitors are widely used in existing lamps, but also did not see so serious consequences. Electronic products can not guarantee that 100% is not damaged, LED products are the same, the rest of the device life lags behind LED devices, the market will force the electrolytic capacitor update or the birth of new devices. Will not affect the development process of LED lighting, worried that it is redundant. Four, the price is too high can not be applied to a large number of LED can learn from Moore's law". Gordon Moore (gordonmoore) to prepare a report on the development trend of computer memory. He sorted out an observation. When he began to draw the data, he found a striking trend. Each new chip generally contains two times the capacity of its predecessor, each chip is generated in the previous chip generated within 18-24 months. If this trend continues, computing power relative to the rise exponentially the time period. The observational data of Moore, which is now called Moore's law, show a trend that continues to this day, and is still unusually accurate. In terms of brightness value is obviously no way to double in 18-24 months, but the decline in price and brightness growth ratio of 18-14 doubled. LED lighting radicals: the formation of the market needs a certain law, publicity too outrageous will affect the development of the industry as a whole, in the long run will also have a negative impact on their own businesses, damage their reputation and interests. LED light conversion efficiency and energy-saving lamps is basically the same, how can design than traditional energy saving lamps are! The most basic concept, can be recycled several power plants by propaganda gorge. It would almost be said that energy shortage is due to LED failed to timely application. The general habit of propaganda that the entire lighting industry, if all of the LED how to use the world? How can the actual diversity of the world? This is a strict stage LED can be used for lighting, LED can be used for street lamps". Is the experimental stage, the price is high, has the environmental protection superiority, the performance price ratio is maladjusted, cannot talk about the energy conservation, the energy conservation is the future. At this stage, not only do not consume a lot of energy saving aluminum. Such as street lamps, design
