Miks on mõned LED-tuled naeruväärselt odavad?
What are the characteristics of China's LED lamp market? The first is the price, the second is the price, and the third is the price. As for technical parameters, service life, and warranty period, Shenma is a cloud. When buyers choose cheap LED lights, they don't think about whether there are manufacturers of such cheap LED lights that can make products of high quality. After all, you can't let LED manufacturers post it upside down. The following are the most typical LED bulbs and LED ceilings. Spotlights are used as an example to illustrate their cost.
Kuidas neid odavaid LED-laeprožektoreid tehakse? LED-lampide maksumus koosneb peamiselt kolmest tükist - lambi helmest, kestast ja ajami toiteallikast. Kui soovite hinda võimalikult madalaks muuta, saate töötada ainult nende kolme aspektiga.
Lambihelmed {{0}} kodumaised 1W lambihelmed Zhongshan Guzhenis müüakse 2 sendiga, miks julgen neid kahe sendi eest müüa? Lambi pärli kuldtraat asendatakse vasktraadiga ja muud toorained halvemate materjalidega, mis on tarbijatele võimatu. See on tajutav ja see on nominaalselt 1 W, kuid seadmete tuvastamisel võib see olla ainult 0,5 W. mis on ebapiisav võimsuskäitumine ja tarbijad seda üldiselt ei testi. Shell - kasutage alumiiniumist või plastikust nurka, hind on 1–3 dollarit.
Drive power supply - there are low-quality drivers on the market that sell for more than 1 yuan, or even lower. I don't know how many manufacturers of LED lights have closed down, and those who are irresponsible for making low-quality drivers for profit, But I don't know how much money I made.
In this way, a 3W LED ceiling spotlight is OK with 3 lamp beads + a shell + a driver, let's calculate the cost of those mid-range goods: lamp beads (2 yuan) + shell (3 yuan) + driver (2.8 yuan) + labor (1 yuan) + packaging (0.5 yuan) + other (1 yuan) = 10.3 yuan. Merchants still have to make money, and no one does business that doesn't make money! In addition to management costs, inventory costs, development costs, etc., there is still about 5% of business extraction. Think about it, will the 3W LED ceiling spotlights sold for less than 10 yuan be qualified products? As for the reasonable price of high-end 3W LED spotlights: lamp beads (6 yuan) + shell (5 yuan) + inner shell (2 yuan) + Drive (5 yuan) + labor (1 yuan) + packaging (1 yuan) + other (1 yuan) = 21 yuan, that is, LED spotlights >21 jüaani on normaalsed ja mõistlikud hinnad!
