LED lighting conservative It is normal for cautious entry in emerging industries, but over-concern, just relying on your own instincts to cut off market results, will miss the opportunity. According to market understanding, the main reasons for the conservative thinking of led lighting are as follows: First, worry that heat dissipation will not be solved very well Cooling mainly depends on the way we design. There is no way to solve it. Actually it is also a cost issue. In the design of LED lamps, the long-term use of the concept of the use of light bulbs (point source), it is always considered difficult to solve the heat. There is no indication that only a design like a light bulb can be widely adopted in the lighting market. The existing traditional concepts should be abandoned, and breakthrough ideas and developments should be made. For example, in the case of existing LED street lamps, why should we design about 100W, why is it not 250w like high-pressure sodium lamps? It is obviously a cost consideration, LED design 250w, LED cost and cooling cost will be much higher, making the cost unacceptable to the market. . It is not designed to have such a large power, nor is it that heat dissipation cannot be solved. At this stage, as long as the LED price is acceptable, the application is better, and it is not limited by the heat dissipation conditions. LEDs cannot be used. The heat dissipation is difficult. On the road of LED development, we need to solve the problem. The heat dissipation is the cost. The problem is not whether it can solve the problem. Temperature, usually a lot of requirements for the surface temperature of led products within 50 ° C, this mentality is wrong. Depending on the specific environmental conditions we use, it is obviously difficult to achieve 50°C on the surface of the product at a temperature of 25 °C. The LED junction temperature needs to be considered most when designing a led product. If the surface temperature is very low, the heat is not dissipated, and the junction temperature exceeds a reasonable value, it is obvious that the product design is very failure! In turn, the thermal resistance of the LED product design is very small, the junction temperature is kept within a reasonable range, and the product case temperature reaches 80 ° C, which is not bad. If you can't touch it, you can judge it as unqualified. How many people dare to touch the appearance of existing traditional lamps and experience the feeling of burns. It is obvious that the temperature of LED lamps is a personal mentality. Second, worry about safety issues LEDs do not have clear documentation to follow and do not affect the LED process. Many products do not have corresponding standards, and they are not all developed well! There is no standard to follow LEDs. LED Christmas lights are not isolated. It has not been used for many years! Some netizens always take a conservative attitude towards the development of led. Existing street lamps, energy-saving lamps (including fluorescent lamps), and spotlights are non-isolated. It is not clear why some friends must isolate LED products. I think it is a typical conservatism mentality. Throughout the previous lighting fixtures are not isolated, the isolation is mostly the adapter and the electronic products that require personnel to operate the contact. Obviously, it is unreasonable to require LED lighting fixtures. LED power supply and current voltage switching power supply products will not be much different in terms of safety regulations. The safety regulations apply to LED products, but the light source is different, there is no essential difference. Even if the new regulations for LED safety are introduced, it will certainly be beneficial to the future development direction of LEDs. Third, worry about the short life of electrolytic capacitors affecting the LED process We can't judge the life of LED products with the life of electrolytic capacitors. The theoretical and actual values ​​will be far from each other. The LEDs in the publicity have a life of 100,000 hours. This theoretical value is hard to prove. Electrolytic capacitors are widely used in existing luminaires and have not seen such serious consequences. Electronic products cannot guarantee 100% undamaged, LED products are the same, other devices lag behind LED devices, and the market will force electrolytic capacitors to be updated or new devices to be born. Will not affect the development of LED lighting, worry is superfluous. Fourth, the price is too high, it is impossible to apply a lot LED development can draw on "Moore's Law". Gordon? Gordonmoore prepares a report on the development of computer memory. He sorted out an observation. When he started drawing data, he found an amazing trend. Each new chip roughly contains twice the capacity of its predecessor, and each chip is produced within 18-24 months of the previous chip. If this trend continues, computing power will increase exponentially relative to the time period. The observations of moore are the so-called moore's laws, and the trends described have continued to this day and are still unusually accurate. As far as the brightness value is raised, there is obviously no way to double the price from 18 to 24 months, but the price reduction and brightness growth are doubled compared to the application of 18-14. Led lighting radical The formation of the market requires certain rules. Propaganda is too outrageous to affect the development of the entire industry. In the long run, it will also have a negative impact on its own business and damage its reputation and interests. Led light conversion efficiency is basically equal to energy-saving lamps, how can we design energy-saving products than traditional lamps! The most basic concept, the publicity can be rebuilt several mountain power stations. I almost said that energy shortage is because LED has not been applied in time. Generally used to propaganda when the entire lighting industry, if you use led? What is the use of the world? Is this possible in a world of actual diversification? Strictly speaking, "led can be used for lighting" "led can be used for street lamps". It is an experimental stage, the price is high, there are environmental advantages, the performance price ratio is out of balance, energy saving is not talked about, energy saving is the future. At this stage, not only does it not save energy, it also consumes a lot of aluminum. For example, street lights, design power is about 100w, why choose this power? It is also mentioned in the foregoing that it is a cost consideration. The basic brightness can meet the needs of national standards. The led price should be reduced as much as possible and can be accepted by customers. Some netizens use 100wled street lamps and 250w sodium lamps to save energy, and take national standards as a reference. The brightness of 250w is not explained. Is this fair? In turn, we can also use the 100w sodium lamp to design a street lamp that meets national standards. What is the difference between this and the current government's emphasis on increasing the temperature of the air conditioner by a few degrees? The radicals are mainly producing LED lighting fixtures and LED production and packaging companies. Of course, we can understand that the position is generally related to the team we are stationed. They usually arm their own slow-moving products and show their contribution to energy saving. In the election campaign, environmental protection is usually the object of publicity, but these will not have enough reason to replace the existing lamps. The most powerful killer in the future is energy saving, but the price is also the decisive factor. In the current LED spotlights, there is no market result we expect, and the cost is the biggest factor. Current drive line status: At present, the market is not very mature in terms of commercial lighting lines, and it is far from the level of traditional lighting. Efficient light sources require efficient drive line support. I personally think that the efficient drive line needs to be more than 90%, which is a must. If we emphasize isolation security, it is obviously impossible to achieve this efficiency. Traditional lamps are not isolated to achieve high efficiency, and led will be the same. We feel that the unsafe is mainly caused by the use of aluminum radiators for LED heat dissipation. It is obvious that we need to change our way of thinking when designing products! In terms of ic design, the LED lighting market is an emerging industry. There is no reference line design. Most ic design companies do not have their own opinions, and often suffer from too many “demand opinionsâ€. Designed to be good, up and down products can be compatible, the last one is "residual". ic design needs to be as perfect as possible, not too compatible. The most interesting ic-amc7169, an ic to be compared with the output of LED, we design 100pcsled street light to use 100pcsamc7169, it is not protection ic, short-circuit voltage reduces the current after rising, it seems to be somewhat destructive! There are problems with designing products. The first is how to solve them, how to avoid them, rather than setting a lot of patches. With such a line, you have very little confidence in your own line, and what else to do! Personally think that in the led design, the most out of the direction of an ic. The most important problem to be solved in the design of mains LED lighting is how to adapt to different load voltage and current changes of LED; mains voltage fluctuation; heat conduction and isolation safety; efficiency cost.
