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 bulb (point source) structure, 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. It is necessary to put aside the existing traditional concepts and have a breakthrough concept and development.
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? Obviously it is 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 and cannot be used. It is difficult to dissipate heat. On the road of LED development, we need to solve it. Heat dissipation is a cost issue, and it is not a solution.
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 heat dissipation resistance of the LED product design is small, the junction temperature is kept within a reasonable range, and the product shell temperature is reached. At 80 ° C, there is nothing wrong with it. 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 feel the feeling of burns. It is obvious that the temperature of LED lighting products is a personal mentality problem.
Second, worry about safety issues
Led does not have clear documentation to follow, does not affect the led process. Many products do not have corresponding standards, not all developed well! led does not follow the standard, led Christmas lights are not isolated, not used for many years! Some netizens always take a conservative attitude towards the development process 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, most of the isolation is 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 the 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 security are introduced, it will certainly be beneficial to the future development direction of LED, and there is no possibility of restrictions.
Third, worry about the short life of electrolytic capacitors affecting the LED process
We can not take the life of the electrolytic capacitor to determine the life of the LED product. The theoretical value and the actual value will be far from each other. The publicity of LED has a life of 100,000 hours. This theoretical value is difficult to prove. Electrolytic capacitors are widely used in existing luminaires and have not seen such serious consequences. Electronic products cannot guarantee 100% damage, 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. 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 in 18-24 months, but the price reduction and brightness growth are doubled compared to the application of 18-14.
Led lighting radicals:
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. The light conversion efficiency of led light is basically equal to that of energy-saving lamps. How can we design a product that is more energy-efficient than traditional lamps? The most basic concept can be re-created by several mountain power stations. I almost said that energy shortage is because LED has not been applied in time. In general, it is customary to say that if the entire lighting industry uses led, what is the use of the world? Is the actual diversified world likely?
Strictly speaking, led can be used for lighting led can be used for street lights. It is an experimental stage, the price is high, there are environmental advantages, the performance price ratio is out of balance, and energy saving is not mentioned, and energy saving is the future. At this stage, not only does it not save energy, it also consumes a lot of aluminum.
For example, the street lamp, the design power is about 100w, why should we choose this power? It is also mentioned in the front is the cost consideration, the basic brightness can meet the national standard needs, 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 use 100w sodium lamps to design street lamps that meet 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 opinions. The design is good, the products can be compatible with the top and bottom, and the last one is the residual. The ic design needs to be as perfect as possible for a product and does not need to be compatible.
The most interesting ic-amc7169, a ic to be compared with the output of LED, we design 100pcsled street light to use 100pcsamc7169, it is not protected ic, short-circuit voltage reduces the current after rising, it seems to be somewhat destructive! Design products have problems, first I want to solve it, how to avoid it, instead of setting a lot of patches. Using such a line, there is very little confidence in the line itself, what else to do! Personally think of an ic that is the most off-direction in the LED design.
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.
