Abstract
The utility model relates to a halogen lamp with enhanced light emission efficiency, belonging to the technical field of photoelectron. The halogen lamp is mainly characterized in that an insulation reflecting layer or a metal reflecting layer is arranged at the bottom inside a lamp tube; the outer wall of a quartz bulb shell has a rough structure; and an optical antireflection film is arranged on the surface of the quartz bulb shell. By adding a reflecting layer on a fixing base inside the quartz bulb shell, most photoelectrons radiating towards the bottom are reflected out, and more light is emitted due to the roughened surface of the quartz bulb shell and the optical antireflection film on the surface, so that the luminous flux is increased greatly; and the halogen lamp is simple in structure but is extremely strong in practicability, and the light emission efficiency is improved greatly.
