LED lights have three large pieces of lights, shells, and drives. If you want to make the price the lowest, then you only have to work hard in these three aspects.
Lamps, the domestic 1W lamp beads, now sell 26 cents on the Guzhen market in Zhongshan City. Why can you sell two cents? The gold wire inside it is not available to consumers. Other raw materials are not replaced with garbage things, and he said that it is 1W. The practical professional equipment is not 1W, maybe 0.5W or even lower, because this consumer can't test it, the shell uses some The corner aluminum or plastic, the cost is 1 to 3 dollars, the drive is the power drive, now the garbage drive on the market has sold more than one, and even lower, here I strongly condemn those A garbage-driven business is not responsible 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 hereby advise those who bought those cheap LED lamps to take the light for the safety of the family’s life and property. Down, you are buying one or even a few bombs at home. This calculated a 3W LED ceiling spotlight is 3 lights a shell and a drive is OK, let's calculate the cost of those mid-range goods: lamp beads (2 yuan) shell (3 yuan) drive (2.8 yuan) manual (1 yuan) Packaging (0.5 yuan) Others (1 yuan) = 10.3 yuan, is such a low price possible? Businesses still have to make money, as well as management costs and inventory costs, as well as development costs and so on. No money to do business no one to do! And Tmall has to take 5 of them to calculate. 10.3 yuan sold LED-3w spotlights, do you dare to use it? Let me tell you the reasonable price of high-end LED spotlight 3W: lamp bead (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, the 21 yuan spotlight is normal and reasonable!
As long as you are paying attention to several aspects in buying lighting, you also choose a good light in the layman.
1, the brightness is different, the price is different. LEDs for LED luminaires should be suitable for laser class 1 standards.
2, anti-static ability of the LED, long life, and therefore high price, usually anti-static than 7000v led can be used for led lighting.
3, LEDs with the same wavelength, the color is the same, if the required color is consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.
4, leakage current LED unidirectional conductive illuminator, if there is reverse current, and become leakage, LED leakage current, short life, low price.
5, the LEDs with different illumination angles have different illumination angles. The specific illuminating angle is more expensive.
6, the key to different quality of life is the life, the life is determined by the light decay. Low light decay, long life and high price.
7, the illuminator of the wafer LED is a wafer, and the price of the different wafers is very different. The chips in Japan and the United States are relatively expensive. Generally, the price of wafers in Taiwan is lower than that in Japan, the United States, and China.
8, the size of the wafer, the size of the wafer is represented by the side length, the large wafer LED is better than the small wafer, and the price is proportional to the size of the wafer.
9, colloidal ordinary LED colloid is generally epoxy resin, LED with anti-ultraviolet and fire retardant is more expensive, high-quality outdoor LED lighting should be resistant to UV and fire. Each product will have different designs. Different designs are suitable for different purposes. The reliability design of LED lighting: electrical safety, fire safety, environmental safety, mechanical safety, health and safety, safety application time and other factors. 10, because LED is a new product, China's national standards lag, but the country provides product qualification tests. Have international safety certification such as (GS, CE, UL, etc.)
11. From a health point of view, the price of products designed with non-toxic materials is high, especially for indoor LED lighting. Don't be greedy and cheap. Use LED lighting with odor. Now only a few manufacturers use non-toxic materials to produce. You can use your nose separately. There are more odors than odorless.
