Xenon Lamp Power Supply for Research-Grade Light Sources

Xenon Lamp Power Supply for Research-Grade Light Sources

Xenon Lamp Power Supply: Principles, Core Functions, and Applications

The Xenon Lamp Power Supply is a specialized electrical driving device designed for xenon lamps (high-intensity discharge lamps, HID). It provides high-voltage triggering and stable current to ensure efficient and safe operation. Xenon lamps are widely used in film, scientific research, and specialized lighting due to their full-spectrum light, which closely resembles sunlight. Xenon lamps are categorized into pulse xenon lamps and continuous xenon lamps, and their corresponding power supplies are similarly classified.

Key Processes in Xenon Lamp Ignition

Working Principle

Triggering Phase: The power supply generates a high-frequency, high-voltage pulse to ionize xenon gas and form a conductive channel.

Stable Arc Phase: Voltage is reduced while high current is supplied to maintain the arc (power can reach several kW to tens of kW).

Cooling Management: Integrated air/water cooling systems ensure stable operation under high temperatures (xenon lamp surface temperatures can reach 800°C).

Core Functions of Xenon Lamp Power Supply

High-Voltage Triggering

Instantaneous high-voltage pulse (15-30 kV): Breaks down xenon gas to form an arc, similar to an "ignition" process.

Low trigger current: Minimizes electrode erosion, extending lamp lifespan.

Stable Arc Power Supply

Constant current/voltage mode: After arc formation, switches to low-voltage, high-current output (e.g., 30V/100A) for stable illumination.

Closed-loop control: Real-time monitoring of voltage and current prevents flickering or arc extinguishing due to power fluctuations.

Multi-Protection Mechanisms

Overvoltage, overcurrent, and overheating protection: Prevents lamp explosion or power supply damage.

Arc detection: Automatically cuts off output upon unexpected arc extinguishing and attempts re-triggering.
