This article aims to provide an in-depth introduction to the purple excitation lamp, covering its working principle, types, applications, and the advantages it offers over other lighting solutions.

Introduction to Purple Excitation Lamp

The purple excitation lamp, also known as a purple light lamp or a violet light lamp, emits light in the purple spectrum. It is primarily used in scientific research, medical diagnostics, and industrial applications. The purple excitation lamp is designed to emit light with a specific wavelength, which is ideal for exciting certain substances and producing visible fluorescence.

Working Principle of Purple Excitation Lamp

The purple excitation lamp works on the principle of photochemistry. It emits light in the purple spectrum, which is absorbed by certain substances. When these substances absorb the purple light, they undergo a chemical reaction that causes them to emit visible light. This phenomenon is known as fluorescence. The purple excitation lamp typically consists of a high-intensity discharge tube filled with a gas mixture that emits purple light. The gas mixture usually contains mercury, which is excited by an electrical discharge to produce purple light. The lamp is also equipped with a filter that selects the purple light and blocks other wavelengths.

Types of Purple Excitation Lamps

There are several types of purple excitation lamps available, each with its own set of features and applications. The most common types include: 1.
