With the continuous development of LED technology, people has developed single LED ship with higher and higher power to adapt to the development of large-area lighting. Currently, the world’s most cutting-edge single LED can already do more than 200W. Although power can be made in high, its cost performance is not so good. Below we will analyze several common LED.
Currently the industry is heavily used single 0.06W power , its maximum brightness can be done 7LM, we do 6LM Zanan general terms, if you want the power of 1W, we need to use the same 17 LED, the total brightness of 17 * 6 = 102LM, ie can be 100LM / W, if we use a single -chip power of 1W , the output of the highest achieved brightness 80LM, used is generally about 60LM, which is on a luminance the main difference , we can see that for home use is concerned, we still have to choose a low-power LED is more appropriate.
From the perspective of product cost , high-power LED cost more than the cost of a low-power , which comes from two aspects, one is the cost of the LED itself , the second is to add high-power LED aluminum heat sink, small power as long as the ordinary circuit board , can be achieved with natural cooling requirements .
Future maintenance costs from a product point of view , if we fail in the use of lighting , you can find any electrical repair shop to replace the damaged LED, an LED 0.06W of cost up to a dollar, plus maintenance fees will not exceed $ 5, if it is to replace one of 1W LED, LED will cost $ 8, plus the cost of necessary repairs around $ 15. And relatively speaking, a small power LED market can easily purchase an electronic market that ‘s not necessarily where power can buy .
High-power LED is not only a market trend but also the mainstream of future development. Since the current techniques still could not achieve our desired results, from a technical point of view, it is not suitable for home lighting.
