Introduction to Purple Excitation Lamp

What is a Purple Excitation Lamp?

A purple excitation lamp, also known as a purple light lamp, is a specialized type of light source that emits light predominantly in the purple spectrum. These lamps are widely used in various industries, including scientific research, medical diagnostics, and industrial applications. The purple excitation lamp operates on the principle of emitting light at a specific wavelength that corresponds to the purple color. This purple light is particularly useful for certain applications where the purple spectrum plays a crucial role.

How Does a Purple Excitation Lamp Work?

The working principle of a purple excitation lamp is based on the emission of light through a specialized phosphor material. The lamp consists of a cathode, an anode, and a phosphor coating. When an electrical current is passed through the cathode, it emits electrons that collide with the phosphor coating. These collisions excite the phosphor material, causing it to emit light at a specific wavelength, which corresponds to the purple spectrum. The purple excitation lamp typically operates at a voltage of around 2.5 to 3.5 volts and a current of 5 to 10 mA. The intensity of the purple light emitted by the lamp can be controlled by adjusting the voltage and current levels. The lamp has a lifespan of several thousand hours, making it a reliable and cost-effective solution for various applications.
