There are several key factors affecting the price of LED lighting product including the COB LED flood light:
1, the Chinese enterprises without core technology
The vast majority of upstream core patents of LED industry lies in the hands of foreigners , Chinese enterprises specializing in COB LED flood light and other commercial and industrial or household LED lighting products have not mastered the core technology , although the capacity of manufacturing LED application products such as COB LED flood light and other finished LED products in China，accounting for 50 % share in the world , but it does account for at least part of the profits.
The main cost of LED lighting is that of LED chip , as long as the prices of chip down , LED lumen unit can be reduced considerably with that of the energy-saving lamps . With the process , the number grow，the costs of LED chip using larger wafers will continue to reduce, of which the rate low by 20% annually in recent years , among the factor on prices of LED chip，the price also includes the enhancement of the efficiency of light, the same price is used to buy a better product , so there is still a significant price cut of the LED chip.
2, it is difficult to cool for LED application products especially the high power LED lights such as COB LED flood light
The cost of cooling maintains the 5% , the effective cooling design is very simple , there are two directions which should know: First , for the LED chip and the path of exterior heat sink, the shorter the better ; Second , heat resistance , which is to have adequate heat conduction path and sufficient ” cooling path .” of which the cost main lie in that of the structure , the cost of structure accounts for about 20% in that of designing the COB LED flood light and other LED lights，the costs is not much for cooling. The biggest problem now is how to create more creative , more reasonable structure design .
3, LED power supply applications
Power is weakest part of COB led flood light and other commercial and industrial or household LED lighting , restricting the development of LED lighting . Design account for about 20% costs of LED lighting, some of which is higher , with the development of technology， the power accounting for about 5-10 % of the cost of the whole COB led flood light and other LED lighting applications is the most reasonable.
Compared to the other afterlife , in fact, the cost of LED light source including the commercial COB LED flood light is not high, especially LED light is known as excellent environmental protection, energy saving, no mercury , and the price of COB LED flood lightand other LED lighting applications are sliding down at every quarter of year, the price of LED lighting will be able to reach an acceptable level of people sooner of later.Browsing http://www.lead-lighting.com/products/bid19-1.htm for the better understanding of COB LED flood light.
