Lamps---------The domestic 1W lamp beads now sell 2-6 cents on the Guzhen market in Zhongshan City. Why can you sell two cents? Copper wire can't be felt by your consumers. Other raw materials do not know you to replace them with garbage. And he said it is 1W. Its practical professional equipment test is not 1W, it may be as low as 0.5W or even lower because This consumer is unable to test it.
Enclosure ----- use some corner aluminum or plastic, costing 1 to 3 dollars,
Drive---------- is the power drive, now the garbage drive on the market has sold more than one piece, and even lower, here I strongly condemn those who do garbage-driven business, 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 would like to advise those who bought those cheap LED lamps to take the light for the safety of the family’s life and property. You are buying one or even a few bombs at home,
This calculated a 3W LED ceiling spotlight is 3 lamp beads + a shell + 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) + labor (1 yuan) + packaging (0.5 yuan) + other (1 yuan) = 10.3 yuan, such a low price is 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! There is also a business extraction of about 5%, you count it. 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 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, the spotlight of > 21 yuan is a normal and reasonable price!
Ok, now I teach you how to choose a good LED light.
Regarding LED lighting , there are several places to note:
1, LED brightness is different, the price is different. LEDs for LED luminaires should be suitable for laser class I standards.
2, anti-static ability of the LED, long life, and therefore high prices. LEDs with an antistatic greater than 700V are usually used for LED lighting.
3. LEDs with the same wavelength have the same color. If the color is consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.
4. Leakage current LED is a unidirectional conductive illuminator. If there is reverse current, it is called leakage, and LED with large leakage current has short life and low price.
5. LEDs with different illumination angles have different illumination angles. The specific illuminating angle is higher in price.
6. The key to different quality of life is life, and life is determined by 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 wafer varies greatly. The chips in Japan and the United States are relatively expensive. Generally, the price of wafers in Taiwan is lower than that in Japan and the United States, and the lowest in China.
8. Wafer Size The size of the wafer is indicated by the side length. The quality of the large wafer LED is better than that of the small wafer. 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 includes electrical safety, fire safety, environmental safety, mechanical safety, health and safety, and safe application time. From the perspective of electrical safety, it should be suitable for relevant international and national standards.
Since LED is a new product, China's national standard lags behind, but the country provides product qualification testing. LED lighting with international safety certification (such as GS, CE, UL, etc.) and national product quality certificate is expensive, because these products are reliable in safety design. The consumer pays attention to the authenticity of the certificate. There are not many manufacturers with international safety certification and national product certification.
From the aspect of health, the price of products designed with non-toxic materials is high, especially for indoor LED lighting. Don't use cheap LED lighting with odor. Now only a few LED manufacturers are producing with non-toxic materials. The method of identification can be directly used for the nose, and the products with odor are much lower than the price without odor. Toxins like lead, mercury, and cadmium require professional analysis. From the perspective of applicable environmental safety, there is a reliable dust-proof and moisture-proof design, and the price of LED products for data fire prevention, UV protection and low temperature cracking is high.
