Analysis of reasons for large price difference of LED lamps

It is the nature of consumers to pursue good and cheap goods, but at this stage, it is still difficult to buy LED lights with low price and high quality. When we buy LED lamps, we will find that even the prices of the same LED lamps vary greatly. First LED and energy-saving lamps. In the big shopping mall, a second-tier brand of spiral 20W energy-saving lamps are priced at 59 yuan. The price of the equivalent LED10W downlight is between 38 yuan and 120 yuan. Just imagine, compared with LED, the technical content of energy-saving lamps is not as high as that of LED, but some LEDs are not as high as the price of energy-saving lamps. Only 38 yuan, does the cost of LED really drop below that of energy-saving lamps, at this stage, it is very difficult; So where is the LED downlight around 100 yuan High? Mainly chips, driving power supplies and heat dissipation materials. Besides, LED with. A 15 w led Downlight, produced by the same manufacturer, has the same appearance, but only one item may have a large price difference; If a 15 w led is made of SMD and the other is made of high-power chips, the cost will be different, and of course the price will be different, obviously, the cost of high power is high, and the price is naturally high. Therefore, the LED price difference is mainly in the following aspects: Chip: is the chip a foreign genuine or non-genuine? Is it a foreign one? The Legion belongs to CREE, OSL and Japan in Europe and America; Others such as purui, Toyota synthesis, Seoul Semiconductor, etc. are also quite good; Taiwan's wafer and New Century correspond to the middle end, and domestic chips are cheaper. Packaging: The same is the use of a better chip, the package is the original package or self-packaging? Is it epoxy or silica gel? Is it a double gold line or a single line? Wait, these all have an impact on the price. Does the chip use high-power LED or SMD as light source? Of course, high-power ones are better. If SMD is used as the light source, then the specification is 3528 or 5050 or other, etc. Of course, the cost of different specifications is different, and the selling price is naturally different. Is the driving circuit constant voltage or constant current? If constant current is used, what kind of constant current circuit is used? Stability and reliability, etc. Some low-end LED lamps are driven by low-cost LED, which will flash and shine in the trial in less than a few months or even a few days. This is caused by the use of inferior driving power supply, of course, the price of such inferior LED lamps is lower. Heat dissipation method: the life of LED has a great relationship with heat dissipation. If heat dissipation is not good, the light attenuation will be very serious, and problems will occur soon. Heat dissipation materials: at present, most LED lamps in China use aluminum materials for heat dissipation, so the effect of using die-cast aluminum and profile aluminum for heat dissipation is different. The latter is of course high in cost and good in heat dissipation effect. Appearance process: Needless to say, consumers can see this. In particular, some LED lamps with poor internal organs but exquisite appearance can especially make some consumers feel good, willing to buy.
