Introduction to Purple Excitation Lamp
What is a Purple Excitation Lamp?
A purple excitation lamp, also known as a purple light lamp, is a type of light source that emits purple light. It is widely used in various fields, such as scientific research, industry, and daily life. The purple excitation lamp has a unique spectral characteristic, which makes it an essential tool in many applications. In this article, we will introduce the purple excitation lamp, its working principle, applications, and future development trends.
Working Principle of Purple Excitation Lamp
The purple excitation lamp is a high-pressure mercury lamp, which emits purple light through the excitation of mercury atoms. When the lamp is powered on, the high-voltage discharge between the electrodes excites the mercury atoms, causing them to emit purple light. The purple light emitted by the lamp has a wavelength range of about 400-450nm, which is in the visible spectrum.
The working principle of the purple excitation lamp can be described as follows:
1. High-voltage discharge: When the lamp is powered on, the high voltage is applied between the electrodes, causing the gas inside the lamp to ionize and form a plasma.
2. Excitation of mercury atoms: The ionized gas emits electrons, which collide with the mercury atoms. The collision energy excites the mercury atoms to a higher energy level.
3. Emission of purple light: The excited mercury atoms return to the ground state by emitting photons. The photons have a wavelength of about 400-450nm, which is purple light.
