The price war of lamps is increasingly fierce, and the products with almost the same appearance, structure and function have a price difference of 2-3 times. Many users are blinded at the moment, and they do not know where the price difference comes from. Generally, LED lighting manufacturers that do not produce LED lighting tubes are generally not produced. It's hard to distinguish, let alone consumers. The market is so chaotic that consumers are always looking at the flowers and can't figure it out. So what are the main factors that cause such a large price gap? What basis should consumers identify for the pros and cons of these products?
The key to different quality of life is life, and life is determined by light decay. Low light decay, long life, long life and high price.
LED chips of the LED light emitter is large chip, different chips, the price difference. The chips in Japan and the United States are more expensive, and the price of LED chips from Taiwanese and Chinese manufacturers is lower than that of Japan and the United States.
Market Analysis: What are the main factors for the price/performance ratio of LED lamps?
The size of the chip size 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 chip size.
The colloid of ordinary colloidal LED is generally epoxy resin, and the LED with anti-ultraviolet and fire retardant is more expensive. The high-quality outdoor LED lighting should be resistant to ultraviolet rays and fire.
The brightness of the brightness LED is different and the price is different. LEDs for LED luminaires shall comply with the laser class I standard.
LEDs with strong antistatic properties have a long life and are therefore expensive. LEDs with an antistatic greater than 700V are usually used for LED lighting.
LEDs with the same wavelength and wavelength have the same color. If the color is the same, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.
The leakage current LED is a unidirectional conductive illuminator. If there is a reverse current, it is called leakage, and the LED with large leakage current has a short life and a low price.
LEDs with different illumination angles have different illumination angles. Special lighting angle, the price is higher. Such as the full diffusing angle, the price is higher.
