Mengapa beberapa lampu LED sangat murah?
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.
Bagaimana lampu sorot langit-langit LED murah itu dibuat? Biaya lampu LED terutama terdiri dari tiga buah - manik-manik lampu, cangkang, dan catu daya penggerak. Jika ingin membuat harga semurah mungkin, Anda hanya bisa menggarap ketiga aspek tersebut.
Manik-manik lampu {{0}} manik-manik lampu 1W domestik di Zhongshan Guzhen dijual seharga 2 sen, mengapa berani menjualnya seharga dua sen? Kawat emas di manik-manik lampu diganti dengan kawat tembaga, dan bahan baku lainnya diganti dengan bahan yang lebih rendah, yang tidak mungkin bagi konsumen Ini dirasakan, dan secara nominal 1W, tetapi mungkin hanya 0,5W ketika dideteksi oleh peralatan, yang merupakan perilaku watt yang tidak mencukupi, dan konsumen umumnya tidak mengujinya. Shell - menggunakan beberapa sudut aluminium atau plastik, biayanya 1 hingga 3 dolar.
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 adalah harga normal dan masuk akal!
