At present, the mainstream products in the lighting market are 5-7W and 9-12W bulbs. Take the 7W LED bulb as an example. The price we surveyed in the sales store in Shenzhen, China is US$14.98 (Taiwan-funded chips) , land-based packaging), first assume that the dealer's profit is 15% ($2.25), and its structural cost is $12.73. After investigation and understanding, the cost of LED light source is about 37.7%, the structural parts account for 18.5%, and the power supply accounts for 21.7%. These three components account for the cost, and the source and power costs still have room to fall.
LED light source (chip, package) market price in the third quarter of 2011 is about 0.92-0.45 US dollars, the average value is 0.68 US dollars / per calculation, 7W products need a total of 7 pieces, that is, the LED light source part is 4.8 The US dollar accounts for about 37.7% of the structural cost. The main part of the structure, including: heat sink parts, connectors, spheres and other components, the price cost of 1.46 US dollars, 0.58 US dollars and 0.68 US dollars, respectively, a total of about 18.5%. The power supply is considered to be a slow link in the development of LED lighting products. Whether it is quality or price to be upgraded and price cuts, power supply accounts for about 2.7% of the structural cost of about 2.76 US dollars, which is also the part to be strengthened. The reasonable range should be in the range below 10%.
