Are LED lights really that good? What is the price now? Tell us about it. 10

Damn, what do you do? Want t4t5? So big? What are you doing? The development of LED is very good, and the high-power ones are generally used in municipal lighting, and the high-power heat dissipation is a problem.

Theoretically, it's good, but it's a new thing, and it is inevitable that there will be problems like this and that, but it will stabilize in a few years, and it will be cheaper.

Now the LED tube has a high and bottom, you have to see what kind of lamp beads and some materials he uses the brand, LED tube must be energy-saving 1 year can save costs. It is recommended that you find a few more manufacturers' ** and compare them.

LED lights have a wide range, I don't know what you mean? I make LED handwriting fluorescent boards!

The lamp beads are different.

LED lamp beads are uneven in the DU market. Why do some lamp dao beads sell cheaply, and some lamp beads ** are dozens of times different, in fact, there is a cat in it. First of all, the materials are definitely the worst, and these raw materials cannot be judged by consumers.

It is only after use that the problem is slowly revealed.

The second is to increase the use of power, the normal use of the lamp beads may only be 1W, the power is increased to 3W, beyond the scope of use, the initial brightness is very high, but the attenuation is very fast, and it will be dark in a few months. Again, it is a virtual standard power, the target is 3W lamp beads, in fact, it is replaced by 1W or lamp beads, or even lower, this consumer is generally unable to test.

The first level of LED chips is not the same, there are imported from, domestic, Taiwan, and mainland. The cheap light fades too quickly, and it won't be long before the lights don't come on. It's just that it's aging too fast.

The light transmittance of acrylic sheets is also different, and the oxidation resistance of acrylic is easy to turn yellow after a long time.

And so on, there are many basebands, aluminum-plastic materials, etc.

The brands are different, the general ones are about 100, and the big brands are about 200.

The brand is different, and the brand is different.

When we purchase a product, we are divided into:

1: Direct costs 2: Indirect costs 3: Maintenance costs, etc.

This is relative, for example: compared to you buying ordinary lamps, the initial purchase cost is low, but the electricity used is more, which is also the cost.

Another example: you buy ordinary lamps with a life span of 5000 hours, but LED lamps may last for 2W hours. It's also the cost.

Many LED lighting manufacturers are using this concept to promote their products.

But having said that, there are too many LED manufacturers now, and if the quality is not up to par, it may not be possible to save the cost in the later stage.

At present, LED is mainly used in public projects and large-scale supermarkets, parking plants, and the development of the civilian market is not ideal.

I don't think there are so many upstairs that I don't get to the point, and the reason is not to say: to cater to the trend, things are expensive. In fact, a 10W LED lamp is equivalent to 30W of the ring lamp fluorescent tube (also the same as the straight tube), and the brightness of the incandescent lamp 4 heads (25W per head) and 6 heads (15W per head) are comparable, and the 10W lamp beads and the current drive (constant voltage + current limiting resistance are the same) are only within 20 yuan, if hundreds of small straw hat heads are used to resist capacitance and reduce voltage and current (most of them on the market are like this), it is only about 10 yuan, expensive because it is trendy, and relatively few, and there are bad businessmen's profiteering. Among them, the profiteering of the merchant is the main driver of the high price, because there are dozens or hundreds of lamp beads on a lamp, and the market price is only a few cents per grain.

The war for lamps and lanterns is becoming increasingly fierce, and the appearance, structure, and function are almost the same products, but the difference is 2 or 3 times, and many users are dizzy for a while.

Brain, I don't know where the price difference comes from, it is difficult to distinguish between LED lighting manufacturers who generally do not produce LED light-emitting tubes, let alone consumers. The market is so chaotic.

As a result, consumers are always confused and confused. So what are the main factors that cause such a big gap? Consumer Judgment.

Don't: What are the bases for the pros and cons of these products?

Life span. The key to different qualities is longevity, which is determined by light decay. The light decay is small, the life is long, the life is long, and the light decay is high.

LED chips.

The light emitter of LED is a chip, and different chips are very different. Chips in Japan and the United States are more expensive, and Taiwanese factories and local manufacturers in China.

LED chips** are lower than those of Japan and the United States.

Market analysis: What are the main factors that affect the cost performance of LED lamps?

Chip size. The size of the chip is expressed in terms of side length, and the quality of large chip LEDs is better than that of small chips. **Proportional to chip size.

Colloid. The colloidal body of ordinary LED is generally epoxy resin, and the LED with anti-ultraviolet and fireproof agent is more expensive, and high-quality outdoor LED lighting should be.

UV and fire resistant.

Brightness. The brightness of LEDs is different, ** different. LEDs used in LED luminaires should meet the laser class standards.

LEDs with strong antistatic ability have a long lifespan and are therefore high. Usually the antistatic is greater than 700V LED can be used for LED lighting.

Wavelength. LED with the same wavelength, the color is consistent, if the color is required to be consistent, it is high. It is difficult for manufacturers who do not have LED spectrochromators to produce pure colors.

products. Leakage current.

LED is a single conductive light-emitting body, if there is a reverse current, it is called leakage, LED with large leakage current, short life, **low.

Beam angle. LEDs emit different light angles depending on their use. Special light angle, ** high. For example, the full diffuse angle is higher.

Having said a lot about the advantages and characteristics of LEDs, I won't talk about the ** of LED lamps, let me analyze the cost of an ordinary LED lamp.

It is divided into three parts, the lamp shell, the light source, and the driver, so **naturally, it is also according to the **change of these three parts, of course, the LED downlight is generally cheaper now.

Basically, it is less than ten yuan, and it is a lot more expensive than a few hundred yuan, and the industrial lighting is even more expensive If you use it at home, I recommend **** to buy it last time.

More than 80 lamps bought for lighting, 60 meters of light strips, very cost-effective, Bigg Lighting, this brand is recommended.

Compared with traditional lamps, it is still expensive, but you have to look at its function, life and power-saving costs, which is much less than using traditional lamps. Now LED lamps and lanterns can not be marketed, and in a few years, LED lamps and lanterns can be compared with energy-saving lamps.

I think the main difference is that the cheap LED light, its quality is not as good as the brand 200 LED light, plus because it is cheap, so its function is relatively simple. <>

When we buy things now, we should not only pay attention to the best price, but also pay attention to the cost performance, such as the quality of the product and its after-sales guarantee. Under normal circumstances, the brand LED lights, their after-sales will be better, will provide a year only to replace the service, this situation when we buy something, even if it is experienced for a few months, there is a problem, it can be better solved. The cheap 20 yuan LED lamp, at most to provide seven days no reason to return, because this kind of lamp is not a fast consumable, that in a short time, through a week, we have no way to judge, this lamp has no quality problems.

From this point of view, you will find that there is a reason why it is expensive, and the LED light of 20 yuan should be the simplest in style and the function is relatively single, but the LED lamp of the brand 200, its function will add more corresponding to its texture and light sense will be better, because the materials used are different, and the effect presented is also different. <>

Especially like online shopping is very developed now, after-sales service is also very important in the process of customer experience shopping, cheap LED lights have its meaning of existence, because it is cheap, and the scope of application is also relatively wide, and the target group is also very large, and from 20 to 200, the difference has reached ten times, and the difference between these ten times can be used to buy other things, so people who do not have too many requirements will still feel more cost-effective and affordable. I think buying things mainly depends on your own needs, ** the same goods must be different, but we should judge which type of goods we should choose more through our own needs, this is the most correct, don't blindly pursue the brand, your own comfort is the most important.
