Abstract
The application provides a fluorescent lamp comprising at least one electric arc tube provided with a tube casing and an accommodating cavity enclosed by the tube casing, a light source arranged in the accommodating cavity of the electric arc tube, and a quantum-dot fluorescent portion is mounted outside the tube casing of the electric arc tube. Because spectrum half-peak width of a quantum dot material is narrow and the quantum dot material has a low self-absorption characteristic even has no self-absorption, light emitted by the light source is combined with the quantum-dot fluorescent portion and luminous efficiency and luminous quality can be effectively improved when the quantum dot material is applied to the fluorescent lamp of the application. A test finds that a colour rendering index of the fluorescent lamp having the quantum-dot fluorescent portion is about 90. The fluorescent lamp can utilize quantum dots in the quantum-dot fluorescent portion instead of halogen powder and phosphor in the prior art, the quantum dots are mounted outside the electric arc tube, so that use time of the quantum dots is greatly prolonged, use cost of the fluorescent lamp is saved and environmental pollution caused by the halogen powder and the phosphor is avoided.
