Abstract

The present invention discloses a high precision exposure lamp. The high precision exposure lamp includes an exposure lamp body, a discharge bulb disposed in the exposure lamp body, and a discharge tube disposed in the discharge bulb; solid mercury is encapsulated in the discharge bulb; the discharge bulb has a first lamp leg and a second lamp leg; the discharge tube has a first electrode and a second electrode, and the first electrode and the first electrode are electrically connected to the first lamp leg and the second lamp leg respectively through a mounting handle; and the discharge bulbis filled with helium gas. Through the above design, the high precision exposure lamp has a long service life and can be quickly started.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to a high-precision exposure lamp. Background technique [0002] Exposure lamps belong to gas discharge lamps, which are electric light sources that use high-pressure mercury vapor discharge to emit light. Because of their short discharge arc and high brightness, they are widely used as light sources in optical imaging systems such as LCD liquid crystal displays and projectors. Generally speaking, the optical system requires the light source to be as close as possible to the point light source and to have high brightness. Mercury vapor discharge usually has strong radiation in the range from ultraviolet light to visible light. The higher the vapor of mercury discharge, the richer the visible light and the higher the arc brightness. When the high-pressure mercury lamp is stably discharged, the mercury vapor partial pressure usually reaches above 10000Pa, which requires th...
