Zašto su neka LED svjetla smiješno jeftina?
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.
Kako se prave ti jeftini LED plafonski reflektori? Cijena LED lampi se uglavnom sastoji od tri komada - perli lampe, školjke i napajanja za pogon. Ako želite da cijena bude što niža, možete raditi samo na ova tri aspekta.
Perle za lampe {{0}} domaće perle od 1W u Zhongshan Guzhenu prodaju se za 2 centa, zašto se usuditi prodati ih za dva centa? Zlatna žica u perli lampe zamijenjena je bakrenom žicom, a ostale sirovine su zamijenjene inferiornim materijalima, što je za potrošače nemoguće. To se percipira, i nominalno je 1W, ali može biti samo 0,5W kada se detektuje opremom, što je nedovoljno ponašanje u vatima, a potrošači ga uglavnom ne testiraju. Shell - koristi ugao od aluminijuma ili plastike, cijena je 1 do 3 dolara.
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 juan su normalne i razumne cijene!
