Abstract

The invention belongs to the field of optics, and discloses a strong light simulation light source lighting device, which comprises a light source, a reflection optical system, a light source focusingassembly, 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, a light source moving platform and a supporting mechanism. When the device works, the light source heat dissipation mechanism, the wind speed acquisition module, the xenon lamp main control system, the xenon lamp electronic ballast and the direct-current stabilized power supply are sequentially turned on; the output of the xenon lamp electronic ballast is adjusted, a xenon lamp in the light source isslowly ignited, a three-axis adjusting mechanism in the light source focusing assembly is adjusted to enable a xenon lamp cathode spot in the light source to coincide with the focus of a parabolic reflector in the reflection optical system, and parallel illumination is output. By adjusting the output power of the xenon lamp electronic ballast and the direct-current stabilized power supply, ambientlight with different color temperatures and different illuminance is obtained, and the photoelectric parameter measurement requirement of the liquid crystal display in the daytime light environment is met.

Description

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