Għaliex xi dwal LED huma ridiculously irħas?
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.
Kif isiru dawk il-spotlajts tas-saqaf LED irħas? L-ispiża tal-lampi LED tikkonsisti prinċipalment fi tliet biċċiet - żibeġ tal-lampa, qoxra, u provvista ta 'enerġija tas-sewqan. Jekk trid tagħmel il-prezz baxx kemm jista 'jkun, tista' taħdem biss fuq dawn it-tliet aspetti.
Żibeġ tal-bozoz {{0}} żibeġ tal-bozoz domestiċi ta '1W f'Zhongshan Guzhen ibiegħu għal 2 ċenteżmi, għaliex DARE li jbiegħhom għal żewġ ċenteżmi? Il-wajer tad-deheb fix-xoffa tal-lampa jinbidel b'wajer tar-ram, u materja prima oħra tinbidel b'materjali inferjuri, li huwa impossibbli għall-konsumaturi Huwa pperċepit, u huwa nominalment 1W, iżda jista 'jkun biss 0.5W meta jinstab minn tagħmir, li hija imġieba ta 'wattage insuffiċjenti, u l-konsumaturi ġeneralment ma jittestjawx. Qoxra - uża xi kantuniera aluminju jew plastik, l-ispiża hija 1 sa 3 dollari.
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 wan huma prezzijiet normali u raġonevoli!
