What are the basic properties of LED fluorescent tubes
With the rush of shopping malls, as consumers, the selection of LED should still be calm, analyze scientifically, and select cost-effective light sources and lamps. The following describes the basic performance of several LEDs:
1. Brightness: the brightness of LED is different, and the price is different. The LED used for LED lamps shall comply with class I standard of laser grade.
2. Antistatic ability: LED with strong antistatic ability has long service life and high price. Generally, led with antistatic voltage greater than 700V can be used for LED lighting.
3. 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 spectrometers to produce products with pure color.
4. Leakage current: LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage. Led with large leakage current has short life and low price.
5. Luminous viewpoint: LEDs with different uses have different luminous viewpoints. Special luminous viewpoint, high price. Such as full diffusion angle, the price is higher.
6. Longevity: the key to different quality is longevity, which is determined by light decay. Small light decay, long life and high price.
7. Chip: the light-emitting body of LED is chip. The price varies greatly with different chips. Chips from Japan and the United States are more expensive. Generally, the prices of chips from Taiwan and China are lower than those from Japan and the United States.
8. Chip size: the size of the chip shows that the quality of large chip LEDs is better than that of small chips. The price is directly proportional to the size of the wafer.
9. Colloid: the colloid of ordinary LED is generally epoxy resin. The LED with fireproof agent is expensive. High quality outdoor LED lighting should be fireproof. Each product will have different plans, and different plans are suitable for different uses.
