Xenon lamp coated with film

The invention provides a xenon lamp coated with film and belongs to the technical field of light source parts. The xenon lamp coated with the film comprises a lamp base, a bulb holder fixed on the lamp base, a bulb inserted into the bulb holder and a lamp filament arranged in a bulb cavity of the bulb. The xenon lamp coated with the film is characterized in that the infrared light reflective film is arranged on the surface of the outer wall of the bulb in a combined mode. Due to the fact that the infrared light reflective film is arranged on the surface of the outer wall of the bulb in the combined model, the infrared light reflective film stops infrared light and prevents the infrared light from scattering towards the outer side of the bulb cavity, and light except the infrared light can scatter outwards. Therefore, the luminous flux, the color temperature and the lighting effect can be improved under the condition of the same power, and energy conservation is reflected. Due to the fact that the shape of the
