Industry conscience: look at how cheap LED light bulb made

What are the characteristics of China's LED lamp market, the first is the price of second is the price of third or price. As for the technical parameters, service life, warranty period god horse is floating clouds. LED lamp buyers will choose cheaper, but buyers do not think so cheap LED lamp manufacturers can make quality products to you, after all, you can not let LED manufacturers pour Post Bar below LED, LED ceiling lamp bulb of the most typical example of the cost data from a light user forum.

The following references at the forum users: the LED ceiling lighting cheap is how to do it? LED the cost of the products are mainly three - beads, shell, driving power, in order to make the price of the lowest then only in the three aspects of Kung fu.

Zhongshan Ancient Town - 1W lamp with lamp domestic selling for 2 cents, 20 Fen why dare to sell gold beads? Inside using copper instead of other raw materials with waste material substitution, the consumers can not perceive, and nominal 1W, but the detection equipment may only 0.5W, consumers are generally not to test.

In some corner of the aluminum shell, or plastic, cost $3 in 1.

Drive power -- now drives rubbish on the market have sold to more than 1, or even lower, how much do LED manufacturers fail and those not for profit irresponsible garbage driven businesses, but I do not know how much money.

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, businesses to make money, and the management cost and inventory cost, development cost and etc.. Do not make money business no one! There are about 5% business extraction, we think about. Below the 3wLED lamp 10 yuan sold will be qualified products? As for the reasonable price of high-grade 3W: LED lamp beads (6 yuan) ($5) + + shell shell ($2) + driver (5 yuan) and artificial (1 yuan) + package ($1) + (1 yuan) =21 yuan, >21 yuan is the lamp is normal and reasonable price!

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

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 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.

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

As for the LED light bulb is similar, take the driving power of the key, the low-end products (including some brands) by RC buck, a resistance capacitance step-down work is: AC 220V --------CBB 400V 105J-------- step-down capacitor input full bridge rectifier internal package 4 diodes in a bridge full wave rectifier circuit in the form of connection and packaging. Voltage regulator tube filter capacitor (parallel) - output, two 474 two 510 inside, this way is relatively extensive, far more than the peak voltage withstand voltage stabilized voltage and capacitance value, easy breakdown, there may cause electrical fires, bring huge risks to users. It was reported that a consumer to buy cheaper LED lamp LED lamp explosion, the bombing of the split, those who buy cheap LED light person is equal to buy a bomb at home, in order to family life and property safety of the best light off.
