The pursuit of high quality and low price products is the nature of consumers, but at this stage, it is more difficult to buy LED lamps with low price and high quality. When we buy LED lamps, we will find that even the price of the same LED lamp is very different. Let's talk about LEDs and energy-saving lamps. In the big shopping mall, the spiral 20W energy-saving lamp of a second-line brand is priced at 59 yuan. The price of the LED10W downlight is equivalent to between 38 yuan and 120 yuan. Imagine that compared with LED, the energy-saving lamp has no high technical content, but some LEDs are not as good as energy-saving lamps. It is only 38 yuan. Does the true LED cost fall below the energy-saving lamps? At this stage, it is difficult. So, is the LED downlight of about 100 yuan high? Mainly chips, drive power and heat sink materials. Let's talk about LED year on year. A 15W LED downlight, produced by the same manufacturer, has the same appearance, but only one item may have a very different price; if a 15W LED is made with SMD and the other is a chip made with high power, then The cost is not the same, of course, the price is not the same, obviously the cost of high-power is higher, the price is naturally higher. Therefore, LED price difference is mainly in the following aspects: Chip: Is the chip genuine or non-authentic? Which is the foreign one? The first-class legion is CREE, OSL and Japan Nichia in Europe and America; others such as Puri, Toyota Synthetic, Seoul Semiconductor, etc., are also quite good; Taiwan’s wafer, new century, etc. correspond to the mid-end, domestic chip prices low. Package: The same is a good chip. Is the package original or self-packaged? Is it epoxy or silicone? Is the double gold wire or single wire used? Wait, these all have an impact on prices. Does the chip use high-power LEDs or SMDs as light sources? Of course, the power is better. If the SMD method is used as the light source, then the specification is 3528 or 5050 or the like, and so on. Of course, the cost is different for different specifications, and the price is naturally different. Is the drive circuit constant voltage or constant current, and what kind of constant current circuit is used if constant current is used? How stable and reliable, and so on. Some low-end LED luminaires use low-cost LED drivers. In less than a few months or even a few days, the trial will flash, which is caused by poor quality drive power. Of course, such inferior LED lamps The price is lower. Heat dissipation method: The life of LED has a great relationship with heat dissipation. The heat dissipation is not good, and the light decay is very serious. It will take a long time to cause problems. Heat-dissipating materials: At present, most of the domestic LED lamps use aluminum materials for heat dissipation. Then, the use of die-cast aluminum and profile aluminum for heat dissipation is not the same. The latter cost is of course high, and the heat dissipation effect is good. Appearance process: Needless to say, consumers can see it. In particular, there are some LED lamps with poor internal organs, but the appearance is very delicate, especially for some consumers who have a good impression and are willing to buy.
Corn Husk Corn Fiber 10%-12%
Corn husk is a by-product of corn deep processing enterprises. The corn granules are immersed and then enter the starch production process, and then processed by washing, squeezing, drying and the like. Its main components are fiber, starch, protein and the like. The corn skin separated by soaking and crushing corn.
Corn Skin has the protein 10%-12% ,12%-14% protein.
