Abstract

The invention belongs to the field of optics, and discloses a strong light analog light source lighting device, comprising: a light source, a reflective optical system, a light source focusing assembly, a light source heat dissipation mechanism, a wind speed acquisition module, a xenon lamp main control system, a xenon lamp electronic ballast, a direct current Stabilized power supply, light source mobile platform and supporting mechanism. When the device of the present invention is working, turn on the heat dissipation mechanism of the light source, the wind speed acquisition module, the main control system of the xenon lamp, the electronic ballast of the xenon lamp, and the DC power supply in sequence, adjust the output of the electronic ballast of the xenon lamp, slowly light the xenon lamp in the light source, and adjust the light source The three-axis adjustment mechanism in the focusing assembly makes the xenon lamp cathode spot in the light source coincide with the focus of the parabolic mirror in the reflection optical system, and outputs parallel light. By adjusting the output power of the xenon lamp electronic ballast and the DC stabilized power supply, different color temperatures and ambient light with different illuminance can be obtained, which meets the photoelectric parameter measurement requirements of the liquid crystal display in the daylight environment.

Description

technical field [0001] The invention belongs to the technical field of optical metrology and testing, and relates to a strong light simulated light source illuminating device, in particular to a strong light simulated light source illuminating device used for measuring and testing luminosity and chromaticity parameters of liquid crystal displays and establishment of a strong light database. Background technique [0002] In the flight display performance test, a light source lighting device is required to simulate the normal cockpit ambient lighting conditions. The illumination range changes from the minimum ambient lighting illumination of 1.1lx to the 86100lx range of direct sunlight on the display screen, and the flight display lighting and bright environment contrast are tested. . In the measurement of photometric and chromatic parameters of active matrix liquid crystal displays, the test equipment needs to be equipped with simulated ambient light and the illuminance is a...
