The truth: how cheap Taobao LED lights do

Strait metropolis online, bought a LED lamp or will buy LED lamps, please look at me, I said the following!!!

I will tell you the Taobao above those cheap LED ceiling lighting lamp is how to do, the LED lamp has three blocks: beads, shell, drive, want to do the lowest price then only in the three aspects of Kung fu.

It made 1W lamp beads -- now the ancient town of Zhongshan city are sold on the market 2 - 6 cents, why can sell 20 Fen of gold, it is not you using copper consumers to feel the raw materials used in other things instead of junk you don't know, but he said 1W. In fact, with professional equipment is not 1W, it may be as long as 0.5W, or even lower, because the consumer is unable to test,

Shell - with some aluminum or plastic edge, the cost of 1 to $3,

Drive - is the power supply, and now the market has more than 1 yuan to drive the sale of the driver, and even lower, where I strongly condemn those who do garbage driven businesses, in order to profit irresponsible.

The last time it was reported that a consumer to buy cheaper LED lamp LED lamp explosion, the bombing of the split, here I advise those who bought those cheap LED lamps of the people, in order to family life and property safety of the best light off, you is to buy one or several bombs in their home. LED ceiling lamp that it is a 3W 3 lamp shell + A + a driver on OK, we count the cost of the intermediate goods: beads (2 yuan) + housing (3 yuan) + driver (2.8 yuan) and artificial (1 yuan) + package (0.5 yuan) the other (1 yuan) =10.3 yuan, so low price possible?

Businesses also want to make money, as well as management costs and inventory costs, as well as development costs, etc.. Don't do business without money! There are also 5% Tmall, you count. 10.3 yuan to sell the LED-3w spotlights you dare to use it?

I'll tell you a reasonable price of high-grade LED lamp: 3W lamp (6 yuan) ($5) + + shell shell ($2) + driver (5 yuan) and artificial (1 yuan) + package ($1) and others (1 yuan) =21 yuan, >21 yuan is the only spot the price is reasonable!

OK, now I'll teach you how to choose a good LED lamp.

About LED lighting, there are several places need to pay attention to:

1, LED brightness is different, the price is different. LED for LED lamps shall be suitable for laser class.

2, antistatic ability of LED, long life, and high price. Usually anti-static 700V greater than LED can be used for LED lighting.

3, the wavelength of the same LED, the same color, such as the requirements of the same color, the price is high. It is very difficult to produce pure color products without the manufacturers of LED spectrophotometer.

4, leakage current LED is a one-way conductive body, if there is a reverse current, it is called leakage, leakage current LED, short life, low price.

5, the use of different luminous angle of LED its luminous angle is not the same. Specific light-emitting angle higher prices.

Key 6, life of different quality is life, life is decided by the light fades. A small decline, long service life, high price.

7, the wafer LED light-emitting chip, different chips, the price difference is very large. Japan, the United States more expensive chips, the average price is lower than in Taiwan, Japan, the United States, the lowest domestic.

8, the size of the chip size to the side of the chip, the quality of the large chip LED is better than small chips. The price is proportional to the size of isomorphous.

9, the gel of the general LED colloid is generally epoxy resin, plus UV and fire retardant LED price is more expensive, high quality outdoor LED lighting should be resistant to ultraviolet light and fire. Each product has a different design, different designs for different purposes, the reliability design of LED lighting style: electrical safety, fire safety, environmental safety, suitable for mechanical safety, health and safety, security application time etc.. From the electrical safety point of view, should be suitable for the relevant international and national standards.

Since LED is a new product, China's national standards lag, but the state provides product qualification test. With international safety certification (such as GS, CE, UL, etc.) and the national product quality certification of LED lighting price is high, because these products are reliable in safety design. Consumers are paying attention to the authenticity of the authenticity of the certificate, there are international security certification and national product certification is not much.

From the health, the use of non-toxic materials designed to high prices, especially indoor LED lighting, do not be cheap to choose the smell of LED lighting. Now only a few LED manufacturers are non-toxic material production, the method can be used directly to identify the nose, the smell of the product is much lower than the price of no smell. Similar to lead, mercury, cadmium and other toxins need professional analysis. From the point of view of the application of environmental safety, there is a reliable dustproof design, data fire, anti UV, anti cracking of low temperature LED product prices.
