Dlaczego niektóre światła LED są absurdalnie tanie?
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.
Jak powstają te tanie reflektory sufitowe LED? Koszt lamp LED składa się głównie z trzech sztuk - koralików lampowych, osłony i zasilacza napędowego. Jeśli chcesz, aby cena była jak najniższa, możesz pracować tylko nad tymi trzema aspektami.
Koraliki do lamp {{0}} krajowe koraliki do lamp 1W w Zhongshan Guzhen sprzedają za 2 centy, po co śmie sprzedawać je za dwa centy? Złoty drut w koraliku lampy jest zastąpiony drutem miedzianym, a inne surowce są zastępowane gorszymi materiałami, co jest niemożliwe dla konsumentów. Jest to postrzegane i nominalnie wynosi 1 W, ale może wynosić tylko 0,5 W po wykryciu przez sprzęt, co jest niewystarczającym zachowaniem mocy, a konsumenci na ogół go nie testują. Shell - używa trochę aluminium lub plastiku, koszt to 1 do 3 dolarów.
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 juanów to normalne i rozsądne ceny!
