Hvorfor er noen LED-lys latterlig billige?
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.
Hvordan lages de billige LED-takspottene? Kostnaden for LED-lamper består hovedsakelig av tre deler - lampeperler, skall og strømforsyning. Hvis du ønsker å gjøre prisen så lav som mulig, kan du kun jobbe med disse tre aspektene.
Lampeperler {{0}} innenlandske 1W lampeperler i Zhongshan Guzhen selges for 2 cent, hvorfor tørre å selge dem for to cent? Gulltråden i lampeperlen er erstattet av kobbertråd, og andre råvarer erstattes av dårligere materialer, noe som er umulig for forbrukerne. Det oppfattes, og det er nominelt 1W, men det kan bare være 0,5W når det oppdages av utstyr, som er utilstrekkelig effektatferd, og forbrukere tester det generelt ikke. Shell - bruker litt hjørnealuminium eller plast, prisen er 1 til 3 dollar.
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 yuan er normale og rimelige priser!
