Factors Causing Price Difference of LED Lamps

At present, LED lamps have entered millions of households. With the popularity of this kind of lamps, more and more people begin to choose LED lamps when decorating. But some people do not know about LED lamps. Compared with traditional lighting lamps, how about LED lamps? What are the factors contributing to the price difference of LED lamps?
How about LED lamps?
I. Effects of LED lamps on health:
Many people will pay attention to the safety of the use of LED lights, which can be analyzed from three perspectives: luminous angle, brightness and wafer light emitting body:
1. Luminescence angle:
The light-emitting angle of the LED lamp will vary according to its use, so the use of the LED lamp should be considered when choosing and purchasing. For example, if it is a background wall, it is better to use the diffuse angle of the LED lamp, but this lamp must not be installed on the desk and the bedside, otherwise it will have a certain impact on the vision.
2. Luminance of LED lamp:
LED lamps should meet the class I standard of laser grade. 1W LED lamp = 3W energy-saving lamp = 15W incandescent lamp, the higher the wattage, the greater the impact on vision, so do not blindly select high wattage LED lamps.
3. Wafer LED Luminescence:
The quality and price of LED lamp chips are also different. Generally, the price of chips imported from the United States and Japan is more expensive, and the quality is guaranteed. The chips made in China are slightly inferior to those made in the United States and Japan.
Performance of LED lamps:
The performance of LED lamps and lanterns is also the most concerned when you select them. The size of wafers, the lifetime and wavelength of lamps and lanterns must be clearly understood before you buy them.
1. Wafer size:
The wafer size of LED lamps is generally expressed by the side length. The quality of large wafer LED is better than that of small wafer.
2. The wavelength is the same:
Wavelength affects the color of LED lamp. Regular LED lamp should have the same wavelength and color. Some manufacturers without LED spectrophotometer can hardly produce pure color LED lamp in production. Therefore, large brands and manufacturers are better to choose when selecting.
3. Different life span:
Lifetime is also the most common concern in the selection of LED lamps. The service life of lamps is determined by the light decay. The light decay of LED lamps means that after a period of lighting, their light intensity will be lower than the original light intensity, and the lower part is the light decay of LED, which has a longer service life.
3. Safety of LED lamps and lanterns:
Although LED lamps are not big items, they also need to use electricity, so they can not be ignored in the use of safety:
1. Leakage current:
Because the LED lamp is a single-guide light emitter, if the reverse current of the LED lamp appears, that is, when the leakage current is too large, the life of the LED will also be reduced, and it will affect the safety of use, easy to cause short-circuit and other situations.
2. Colloid of LED lamps:
Generally speaking, the colloid of LED is epoxy resin. When selecting, we can choose products with anti-ultraviolet and fire retardant. Although the price is high, the safety of LED lamps with these functions will be improved.
3. Antistatic ability:
The stronger the anti-static ability of the LED lamp, the longer its service life. Generally speaking, the LED lamp with anti-static capacity greater than 700V is qualified.
If the above is about the performance, safety and other aspects of LED lamps, I believe that through the above introduction, you will have a further understanding and understanding of the LED lights, as for the quality of LED lamps, I suggest that you better choose according to your own preferences, the current market price of LED lamps is high or low, in the end is: What causes it? Let's take a look at the following factors which cause the price difference of LED lamps.
The factors causing the price difference of LED lamps are as follows:
1. Brightness:
The brightness and price of LED are different.
2. Antistatic ability:
LED with strong antistatic ability has long life and high price. Usually, LED with antistatic capacity greater than 700V can be used for LED lighting.
3. Luminescence angle:
Different uses of LED light-emitting angle is different, special light-emitting angle, higher price. If full diffuse angle, the price is higher.
4. Life span:
Lifetime is the key to different qualities. Lifetime is determined by light decay. Low light decay, long life, long life and high price.
5. Wavelength:
LED with the same wavelength and color will cost more. It is difficult for manufacturers without LED spectrophotometer to produce pure color products.
6. Leakage current:
LED is a single-guide light emitter, if there is a reverse current, it is called leakage, leakage current large LED, short life, low price.
7. LED chip:
LED emitter is chips, different chips, prices vary greatly. Chips in Japan and the United States are more expensive. The price of LED chips from Taiwan factories and Chinese manufacturers is lower than that of Japan and the United States.
8. Chip size:
The size of the chip is expressed by the side length. The quality of large chip LED is better than that of small chip. The price is proportional to the size of the chip.
9. Colloid:
The colloid of ordinary LED is generally epoxy resin, and the price of LED with anti-ultraviolet and fire retardant is more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fire.
