Fluorescent lamps are also known as fluorescent lamps. Traditional fluorescent lamps, also known as low-pressure mercury lamps, use low-pressure mercury vapor to release ultraviolet light after being electrified, causing the fluorescent powder to emit visible light. Therefore, they belong to low-pressure arc discharge light sources. In 1974, Philips in the Netherlands first developed a fluorescent powder that emits red, green, and blue light that is sensitive to the human eye. The development and application of three primary colors (also known as three primary colors) fluorescent powder is an important milestone in the development history of fluorescent lamps
Selection principle
1. In any case, thin tube diameter (tube diameter ≤ 26mm) lamps, such as T8, T5, etc., should be used to replace T12 lamps, which has obvious energy-saving and environmental protection effects
