This paper analyzes the minimum cost of manufacturing an LED bulb at the current cost price. Perhaps over time, in the future, the price of LEDs can really be reduced to some low price prices. But at the moment, it is really difficult to achieve. Insiders pointed out that we should put an end to low-price bidding, oppose vicious competition, and achieve healthy, orderly and scientific industrial development on the basis of quality and safety.
Take the 3W ceiling spotlight as an example. The following tells you how the low-priced LED ceiling spotlights are made. Let's take a look at the following advertisements. God, 3W spotlights range from 5.8 yuan to 8 yuan, while brand factories generally cost more than 20 yuan.
Figure 1: Low-cost LED light advertising
The structure of the LED luminaire consists of three parts, namely the lamp bead, the outer casing and the power supply. To make the price low, it is necessary to work hard in these three aspects.
Lamp Beads - Anti-Liu Ming 1W lamp beads in the Zhongshan Guzhen market at the lowest 0.3 yuan / PCS, 3W spotlights need 3, the cost of lamp beads as long as 0.9 yuan. 1W's lamp beads only sell 3 cents, and the brand factory's lamp beads must be at least 1 yuan. Why can it be sold so cheaply? In fact, it is tricky. First of all, its material is definitely the worst. For example, the wire is replaced by a copper wire instead of a gold wire. The bracket is made of recycled materials or scrap. The raw materials are not judged by the consumers. Only after the use is the problem is slowly exposed. come out. The second is to increase the power usage. Originally, the normal use power of the lamp bead is 0.5W, and the power is added to 1W, which is beyond the scope of use. The initial brightness is very high, but the attenuation is very fast, and it is dark in a few months. Again, the virtual standard power, the standard is 1W lamp beads, the actual standard may have 0.5W, or even lower, this consumer is generally not tested. Look at the above ads, the first one is intriguing, the 12W spotlights are labeled "foot tiles", but the 3W is not marked, I think everyone already understands.
Enclosure - with some corner aluminum or impurity aluminum or thin aluminum or even plastic shell, the cost is low, between 1 and 3 dollars.
Power supply - Now there is more than one power supply for garbage on the market, and even lower. This power supply is said to be a constant current source, but it is a time bomb. Designed to cut corners, anti-surge, rectification and filtering, steady flow can save provinces, can not save and save, electronic components are also useful for recycling materials, regardless of safety. Here, we must strongly condemn those manufacturers who do garbage power, and manufacture time bombs one by one, irresponsible for profit. Last time there was a news report that a consumer bought a cheap LED light to explode, and the LED light was blown apart. I would like to advise those who bought cheap LED lamps to change the LED lights for the safety of their families. You are not at home with LED lights but time bombs!

In this way, we roughly estimate what the cost of 3W ceiling spotlights is. Cheap junk goods: 3 lamp beads and light board (1 yuan) + shell (3 yuan) + power supply (1.5 yuan) + artificial water power (1 yuan) + packaging (0.5 yuan) = 7 yuan, so count 7 The cost of the yuan, the merchants have to make money, as well as management costs, inventory costs, development costs, business commissions, etc., how to make money at such low prices. The business that does not make money is definitely not made by anyone. The manufacturer can sell such a low price. It must be earned by money. Then save the material, save the province, and save the 7W 3W ceiling spotlight. Is it reasonable? The reasonable price of 3W ceiling spotlight with quality assurance should be: Lamp bead (4.5 yuan) + shell (6.5 yuan) + power supply (4 yuan) + artificial hydropower (1 yuan) + packaging (1 yuan) = 17 yuan With management, research and development and other related expenses, the price is more than 20 yuan is also normal. From the cost point of view, a good ceiling spotlights of at least 17 yuan is a normal and reasonable price!
After reading the above analysis, you should know whether you want to buy LED lights or buy a time bomb. You can do it yourself.
