Where is the price of led three-proof lamps and lanterns generally expensive?
Why is the price of LED three-proof lamps so expensive? This is a question that many LED lighting consumers want to know. As incandescent lamps gradually withdraw from the market, LED lamps quickly occupy the lighting market due to their environmental protection and energy-saving features; they also lose most of the market because of their high prices. At present, the market share of LED lamps is about half, but it has not been able to break through. Although there is a competition for lamps such as energy-saving lamps, the fundamental reason is that the price is too high.
Why is the price of LED lamps so high? Because of its high cost ratio, especially for domestic. The three-proof lighting manufacturers summarize that LEDs are expensive for three reasons:
First of all, the domestic LED industry does not have its own core skills. Many high-end LED technologies are in the hands of scientific researchers in European and American countries. Therefore, domestic LED products only occupy a profit share in the production of products. Due to the continuous development and development of LED chips, its many applications will reduce the overall cost of LED products. However, at present, my country's LED chips are mostly imported from abroad, so the cost of construction is very expensive.
Secondly, LED products are difficult to dissipate heat. Because of this feature, when manufacturers manufacture LED products, they often spend a certain amount of money on the manufacture of heat sink materials. Therefore, to reduce the price of LED products, we can start from reducing the cost of heat dissipation.
Since the power supply is the weakest link of LED products, it accounts for 20% of the total cost of LED products. Therefore, if manufacturers increase the use of power tubes for LEDs
