Because manufacturers have relatively low barriers  entry, most of them are assembled in parts. Their testing equipment, methods are lacking, and standards are not the same. This also makes the quality of LED lighting products on the market uneven. Because of fierce competition, companies The price war is fierce. Even though the appearance, structure, and function of LED lamps are basically the same, their prices can differ by 2-3 times, which confuses many consumers. Next, let me introduce you  LEDs. Selection, what are the facrs that affect the price of LED lamps?

　　LED lamps introduction: LED lamps, also known as light-emitting diode lamps, can transmit light, distribute and change the distribution of LED light sources. The basic structure of LED lamps is a semiconducr material chip, which has a strong anti-vibration function. It has many advantages, such as: safety and efficiency, energy saving, long use time, etc.

　　Advantages of LED lamps:

　　1. Safe and energy-saving, LED lamps are very energy-saving, 60W incandescent lamp consumes 1 kWh for 17 hours;

　　2. The use time is long, the semiconducr chip emits light, does not need filament, glass bulb, shock resistance, and is not easy  break. The use time reaches 50,000 hours, while the use time of ordinary incandescent lamps is only 1,000 hours;

　　3. The color is environmentally friendly, no mercury and xenon elements, no electromagnetic interference, easy  recycle;

　　4. Relatively healthy, there is no ultraviolet and infrared rays, no radiation, and harmless  health.

　　Nine facrs that determine the price of LED lamps

　　1. Wavelength

　　The cost of purchasing LED tubes with the same emission wavelength will be higher. The color must be consistent, it is difficult  screen without an LED spectrophometer, and the purchase of a spectrophometer will increase the production cost.

　　2. LED chip

　　Different chips have different prices. Frequently seen chips are LED chips from Japan, the United States, Taiwan, and local Chinese manufacturers. Among them, Japanese and American chip prices are relatively high.

　　3. Brightness

　　The price will be different if the brightness is different. The luminous efficiency of the die is relatively high, more than 100 lumens per watt, and the power is greater than 3 watts, and its price is higher than other performance specifications.

　　4. Chip size

　　If the chip is large, the die matrix is ??large, the heat dissipation effect is better, and the power it bears is also large. Then its price is proportional  the size of the chip.

　　5. Leakage current

　　The leakage current is relatively large, the tube consumption is large, and the use time is relatively short, so its price is relatively low.

　　6. Electricity

　　If the antistatic ability is relatively poor, the luminous tube will be easily broken down and damaged. Strong antistatic ability, long use time, stable quality, high price.

　　7. Life

　　The greater the working current, the faster the light decay and the longer the use time. The price is higher for the long-term use.

　　8. Light angle

　　For different purposes, its light-emitting angle is different. If it is a special light-emitting angle, then the price is relatively high. For example, the full diffusion angle.

　　9, colloid

　　Ordinary colloid is basically epoxy resin, high-quality outdoor LED lamps, UV-resistant and fire-resistant, and the price is relatively high.
