1、The Working Principle of UV Photocatalyst Lamp

UV photocatalyst lamp, as the name suggests, is a lamp that combines ultraviolet (UV) technology and photocatalyst technology. Its working principle is primarily based on the catalytic effect of photocatalyst materials under UV irradiation. The photocatalyst, typically represented by nano-scale titanium dioxide (TiO₂), is a semiconductor material with photocatalytic properties.When ultraviolet light irradiates the surface of the photocatalyst, it excites electrons on the surface, causing them to transition to a higher energy level. This process generates highly active hydroxyl radicals and negative oxygen ions. These active ion groups can decompose harmful substances in the air, such as bacteria, viruses, formaldehyde, and benzene, oxidizing and reducing them into harmless carbon dioxide and water.

The UV light sources used in UV photocatalyst lamps are mainly categorized into low-pressure amalgam lamps, medium-pressure amalgam lamps, and UV LED lamps. Low-pressure amalgam lamps primarily emit UVA and a small amount of UVB, making them suitable for curing and analytical detection. Medium-pressure amalgam lamps emit UVA, UVB, and UVC, making them suitable for high-intensity UV applications such as disinfection. In recent years, UV LED lamps have become the mainstream light source for UV photocatalyst lamps due to their long lifespan, low energy consumption, and fast response time.

3、Types of UV Photocatalyst Lamps

UV photocatalyst lamps can be classified into various types based on the light source and photocatalyst materials. Among them, CCFL (Cold Cathode Fluorescent Lamp) photocatalyst lamps are widely popular in the market due to their soft light, high energy efficiency, and long lifespan. CCFL generates UV-C ultraviolet light through the principle of cold cathode electron emission. When this ultraviolet light irradiates the photocatalyst material, it activates the catalyst on the surface, producing a highly efficient photocatalytic effect.

Furthermore, with advancements in technology, lamps incorporating visible light photocatalyst technology have emerged in the market. These lamps utilize visible light photocatalyst materials to absorb light energy, generating highly active hydroxyl radicals and negative oxygen ions to achieve air purification. One of the leading products in this category is the visible light photocatalyst lamp developed by Foshan Lighting. These lamps are not only safe and environmentally friendly but also provide thorough purification and allow coexistence with humans. Additionally, they continuously release negative oxygen ions, which help boost the human immune system, creating a healthy and comfortable living environment for users.

3、Advantages of UV Photocatalyst Lamps

l Sterilization and Disinfection: UV photocatalyst lamps can effectively eliminate bacteria, viruses, and other harmful microorganisms in the air, providing users with a cleaner and healthier living environment. They are particularly essential for vulnerable groups such as infants, pregnant women, and the elderly.

l Air Purification: UV photocatalyst lamps can decompose harmful substances such as formaldehyde and benzene in the air, oxidizing and reducing them into harmless carbon dioxide and water, thereby effectively purifying indoor air.

l Energy Efficiency and Environmental Protection: Utilizing advanced energy-saving technology, UV photocatalyst lamps efficiently reduce energy consumption. Additionally, the photocatalyst material acts as a catalyst and is not consumed during the reaction, making it highly cost-effective.

l Soft and Comfortable Light: The gentle and comfortable light emitted by UV photocatalyst lamps helps create a warm and tranquil living environment.

l Long Lifespan: UV photocatalyst lamps have an extended lifespan of tens of thousands of hours, reducing the hassle of frequent bulb replacements.
