1, the luminescence principle is different
Ordinary lamp tube is fluorescent lamp, and its luminous principle is different from that of LED lamp tube. Fluorescent lighting means that the ballast generates high voltage at the moment of power-on, which excites the discharge between two pins inside the lamp tube, and then excites the fluorescent powder to emit light. This process produces a high fever. LED luminescence is the luminescence produced by electron migration inside the semiconductor, and the luminescence process does not produce heat.
2. Different energy consumption
Ordinary lighting lamps will generate a lot of heat energy, while LED fluorescent lamps will all be converted into light energy, which will not cause energy waste. Operating costs depend on power consumption and maintenance costs.
3, the life span is different
The service life of LED can reach more than 50,000 hours (excluding power supply), with long service life, stable performance and low environmental requirements. Replacing LED lamps every 65,438+00 years not only saves electricity but also avoids the pain of frequent lamp replacement. Service life of general lighting (excluding power supply) 10000-20000 hours.
