Pulse type xenon lamp driver

Abstract

The invention discloses a pulse type xenon lamp driver, comprising an AC220V, an AC-DC power supply circuit, a charging circuit, a capacitor bank, a discharge resistor, a main control board, an IGBT driver, an IGBT, a first diode, a temperature detector, a high voltage board, a second diode and a xenon lamp; the AC220V is connected to the AC-DC power supply circuit, the AC-DC power supply circuitis connected to the charging circuit and the main control board, the charging circuit and the main control board are bidirectionally transmitted, and the charging circuit is connected to the capacitorbank, the temperature detector is connected to the main control board, the main control board is connected to the IGBT driver, the IGBT driver is connected to the IGBT, the IGBT is connected to a positive pole of the capacitor bank and the first diode, and a negative pole of the capacitor bank is connected to the discharge resistor and the xenon lamp. According to the pulse type xenon lamp driverin the invention, the IGBT is used as a high-speed switch, the switching speed is fast, and the output pulse waveform is a square wave, thereby improving the efficiency of the xenon lamp.

Description

technical field [0001] The invention relates to the technical field of xenon lamp drivers, in particular to a pulsed xenon lamp driver. Background technique [0002] Xenon lamp is a kind of xenon lamp filled with 0.019-0.0266MPa high-pressure xenon in the ellipsoidal quartz bulb, and the distance between electrodes is less than 10mm. The characteristics of the short-arc light source, after years of development and improvement, the ultra-high-voltage short-arc xenon lamp was officially launched to the market in 1951. In 1954, at the World Lighting and Film Fair in Cologne, Germany, Zeiss-Ikon exhibited the first As a xenon lamp for film projection, the Netherlands, Japan, the United States, the United Kingdom, the Soviet Union and China have successively developed and produced xenon lamps for film projection of various specifications. Since then, ultra-high pressure short-arc xenon lamps have replaced carbon arcs in most theaters in the world. The light source has become a n...

[0002] Xenon lamp is a kind of xenon lamp filled with 0.019-0.0266MPa high-pressure xenon in the ellipsoidal quartz bulb, and the distance between electrodes is less than 10mm. The characteristics of the short-arc light source, after years of development and improvement, the ultra-high-voltage short-arc xenon lamp was officially launched to the market in 1951. In 1954, at the World Lighting and Film Fair in Cologne, Germany, Zeiss-Ikon exhibited the first As a xenon lamp for film projection, the Netherlands, Japan, the United States, the United Kingdom, the Soviet Union and China have successively developed and produced xenon lamps for film projection of various specifications. Since then, ultra-high pressure short-arc xenon lamps have replaced carbon arcs in most theaters in the world. The light source has become a new light source for film projection. Xenon lamps can be divided into three types: natural cooling, air cooling and water cooling according to their characteristics. Water cooling, but the use efficiency of the existing xenon lamp is low, it is not convenient to meet the needs of people
