Pourquoi certaines lampes à LED sont-elles ridiculement bon marché ?
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.
Comment sont fabriqués ces spots de plafond à LED bon marché ? Le coût des lampes à LED se compose principalement de trois pièces - perles de lampe, coque et alimentation électrique. Si vous souhaitez rendre le prix le plus bas possible, vous ne pouvez travailler que sur ces trois aspects.
Perles de lampe {{0}} perles de lampe domestiques 1W à Zhongshan Guzhen se vendent 2 cents, pourquoi oser les vendre pour deux cents ? Le fil d'or dans le cordon de la lampe est remplacé par du fil de cuivre et les autres matières premières sont remplacées par des matériaux de qualité inférieure, ce qui est impossible pour les consommateurs. Il est perçu et il est nominalement de 1 W, mais il ne peut être que de 0,5 W lorsqu'il est détecté par un équipement, qui est un comportement de puissance insuffisant, et les consommateurs ne le testent généralement pas. Shell - utilise des coins en aluminium ou en plastique, le coût est de 1 à 3 dollars.
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 yuans sont des prix normaux et raisonnables !
