What factors will affect the price of LED lamps?
Market analysis: What are the main factors affecting the cost performance of LED lamps?
The price war of LED lamps is becoming increasingly fierce. Products with almost the same appearance, structure and function have a price difference of 2 to 3 times. Many users are confused for a while. LED lighting manufacturers are difficult to distinguish, let alone consumers.
The LED lighting market is so chaotic that consumers are always confused and confused. So what are the main factors that cause such a large LED lamp price gap? What basis should consumers find for judging the pros and cons of these LED lighting products?
1. LED lamp life
The key to different qualities is life, and life is determined by light decay. Low light decay, long life, long life, high price. Including heat dissipation
2. LED chip
The luminous body of the LED is a chip, and the price of different chips varies greatly. Chips in Japan and the United States are more expensive, while the prices of LED chips from Taiwanese and Chinese manufacturers are lower than those in Japan and the United States.
3. Chip size
The size of the chip is expressed by the side length, and the quality of the large chip LED is better than that of the small chip. The price is proportional to the size of the chip. 10*16, 9*26, etc. chips
4. Colloid
The colloid of ordinary LEDs is generally epoxy resin, and LEDs with anti-ultraviolet and fire retardants are more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof.
5. Wavelength
LEDs with the same wavelength have the same color. If the color is required to be the same, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure colors.
brightness
The brightness of the LED is different, and the price is different. The LEDs used in LED lamps should meet the laser class Ⅰ standard. 5-6lm and 10-20lm, the price is very different
LEDs with strong antistatic ability have long life and are therefore expensive. Generally, LEDs with anti-static voltage greater than 700V can be used for LED lighting.
6 Leakage current
LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage. LEDs with large leakage current have short life and low price.
7 beam angle
LEDs with different purposes have different light-emitting angles. The price of LED lamps is higher for special light-emitting angles. Such as full diffusion angle, the price is higher. 3014 is much larger than 3528 or 5630.
8 Lamp materials
High-quality aluminum alloy, oxidized aluminum, PC material. . .
9. The quality of the power supply
