At present, the market there are many low-cost low-quality LED lights, many people may wonder, those cheap LED lights in the end is how to do it?

What is the characteristics of China's LED lights market? The first is the price, the second is the price, the third or the price. As for the technical parameters, life, warranty period God horse are clouds. But is that really okay? Do you think about quality and safety?

Buyers will choose cheap LED lights, but buyers do not think so low LED lights manufacturers have to make quality products to you? After all, you can not let LED manufacturers to bar it, the following to the most typical LED bulbs and LED ceiling light as an example to illustrate the cost.

Cheap LED ceiling light is how to do it?

LED lighting costs are mainly three - lamp beads, shell, drive power. In order to do the lowest price so that only in these three aspects of the effort.

Lamp beads

Made 1W lamp beads have to sell 2 cents, why the two cents dare to sell?

Lamps inside the gold wire with copper instead of other raw materials with low-quality materials to replace, which is the consumer can not detect, and the nominal 1W, but the equipment may be detected only 0.5W, and consumers are generally not Will go to test.

shell

With some corners of aluminum or plastic, the cost of 1 to 3 dollars.

Drive power

Now the market is driven by a poor quality of more than one, and even lower, do the LED lights manufacturers do not know how many of the collapse, and those who do not responsible for profitability to do poor quality drive business, but I do not know earned how much is it.



So doing, a 3W LED ceiling light is 3 lamp beads + a shell + a drive on the OK, and we count about:

Mid-range goods costs:

(2 yuan) + shell (3 yuan) + drive (2.8 yuan) + artificial (1 yuan) + packaging (0.5 yuan) + other (1 yuan) = 10.3 yuan.

Businessmen have to make money, do not make money business no one to do! Plus management costs, inventory costs and development costs, etc., as well as business extraction of about 5%. We think about, less than 10 yuan to sell 3W LED ceiling light will be qualified products?

High-grade 3W LED spotlights reasonable price:

(5 yuan) + artificial (1 yuan) + packaging (1 yuan) + other (1 yuan) = 21 yuan, which is the> 21 yuan LED lighting is the normal and reasonable price!

How to choose a good LED lighting it?



1, LED brightness is different, the price is different. LED for LED lamps should be suitable for laser class Ⅰ standard.

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

3, the same wavelength of the LED, the same color, such as the requirements of the same color, the price is high Producers who do not have LED spectrophotometers are difficult to produce pure color products.

4, leakage current, LED is a one-way conductive light, if there is reverse current, then known as leakage, leakage current LED, short life, low prices.

5, light angle, the use of different LED light angle is not the same. Specific luminous angle price is higher.

6, life, the key to different quality of life, life is determined by the light fade. Light fades small, long life, high prices.

7, chip, LED luminous body for the wafer, different chips, the price difference is very large. Japan, the United States of the chip is more expensive, the general price of Taiwan's chip is lower than Japan, the United States, the lowest domestic

8, colloid, colloid of ordinary LED is generally epoxy resin, plus anti-ultraviolet and fire agent LED price is more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fire.

From the health side

The use of non-toxic materials designed to high prices, especially indoor LED lighting, do not choose cheap cheap LED lighting. Now only a few LED manufacturers are non-toxic materials, can be used directly to the nose to smell, smell the product than the odor-free price is much lower, which contains excessive lead, mercury, cadmium and other toxins.

From the perspective of environmental safety

There is a reliable dust and moisture-proof design, materials, fire, anti-ultraviolet, anti-low temperature cracking of the high price of LED products.

As for the LED bulb is similar, take the most critical drive power, the low-end products (including some big brands) using RC capacity step-down, RC capacity of the work is: AC 220V input - CBB step-down capacitor 400V 105J - full bridge rectifier, the internal package 4 diodes are connected and encapsulated in the form of bridge full-wave rectifier circuit - regulator tube, filter capacitor (parallel) - output, internal with two 474 and two 510.

This way is relatively extensive, the peak voltage is far more than the voltage regulator and capacitor voltage, it is easy to breakdown, may lead to electrical fires, to the user a huge hidden dangers.

There are news reports a consumer bought a cheap LED lights exploded, LED lights fried apart, those who bought a cheap LED lights is equal to buy a time bomb at home, for the family's life and property safety best to put the light Take it down.
