Xenon lamp power source for instrument

Abstract

The invention relates to a xenon lamp power supply for instruments, which includes a liquid crystal display screen, keys, a xenon lamp power supply and a xenon lamp lamp body composed of a xenon lamp high-voltage trigger and a xenon lamp; The display screen displays; the xenon lamp power supply ignites and triggers the xenon lamp lamp body according to the control current value of the xenon lamp; the xenon lamp power supply includes a power conversion circuit, a liquid crystal interface circuit and a button interface circuit for connecting the LCD screen and buttons, and the xenon lamp control current value input by the buttons is input into the microcontroller The power conversion circuit is externally connected to a 24V DC switching power supply, and the constant current switching circuit switches the cathode of the xenon lamp body to connect to the 24V power supply ground under the control of the single-chip microcomputer, and the ignition trigger module works to ignite the xenon lamp body; after the xenon lamp is ignited, the xenon lamp body enters a constant current Working mode: The xenon lamp working voltage acquisition module transmits the collected xenon lamp working voltage to the single-chip microcomputer, and the liquid crystal display displays the xenon lamp working voltage after being processed by the single-chip microcomputer. The invention can be widely applied in various xenon lamp power supply.

Description

technical field [0001] The invention relates to a xenon lamp power supply, in particular to an instrument xenon lamp power supply. Background technique [0002] The spectral range of the xenon lamp is relatively wide, and its spectrum covers the range from 200nm to 2000nm, and it is a continuous spectrum. In the ultraviolet part from 200nm to 400nm, the spectrum of the xenon lamp is a continuous spectrum. In the visible light region from 400 to 700nm, the spectrum of the xenon lamp is close to the black body radiation of 6200K, the radiation energy is almost equal, and the spectral characteristics basically do not change with the power of the light source. In this range, The xenon light source can simulate the solar spectrum very well. However, there are discrete spectral lines superimposed in the range of 450nm and 700nm, which are the line spectra emitted by xenon atoms transitioning at higher energy levels; in the near-infrared region of 800-1000nm, atomic characteristic...
