What are the factors affecting the cost performance of LED lamps
The price war of led lamps is becoming increasingly fierce. Products with almost the same appearance and functions have several times the price difference. I don't know where the price difference of LED lamps comes from. It is difficult for LED manufacturers to distinguish, let alone consumers. The LED lighting market is so chaotic that consumers are always confused. What are the main factors that cause such a large LED lamp price gap?
LED lamp life; the key to different quality is life, life is determined by light decay. Low light decay, long life, long life, high price.
LED chip; LED's luminous body 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.
Market analysis: What are the main factors affecting the cost performance of LED lamps?
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.
Colloid: The colloid of ordinary LEDs is generally epoxy resin. LEDs with anti-ultraviolet and fire retardant are more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof.
Brightness: The brightness of LED is different, and the price is different. The LED used for LED lamps should meet the laser class I standard.
LEDs with strong antistatic ability have a long life and are therefore expensive. Generally, LEDs with anti-static voltage greater than 700V can be used for LED lighting.
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.
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.
Light-emitting angle; LEDs with different uses 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
