History of Refrigerator Lamp Tube Industry

The refrigerator lamp tube industry has a long history, dating back to the early 20th century. The first refrigerator lamp tube was invented by Nikola Tesla in 1891. However, it was not until the 1930s that the industry began to take off, with the development of fluorescent lighting technology. Since then, refrigerator lamp tubes have become an integral part of refrigeration equipment, playing a crucial role in energy conservation and environmental protection.

Manufacturing Process of Refrigerator Lamp Tube

The manufacturing process of refrigerator lamp tubes involves several steps, including glass tube production, phosphor coating, and electrode insertion. Here is a brief overview of the process: 1. Glass Tube Production: The first step is to produce the glass tube, which is made of special glass materials that can withstand the high temperatures and pressures inside the refrigerator. The glass tube is then coated with a thin layer of phosphor to emit light. 2. Phosphor Coating: The phosphor coating is a crucial part of the manufacturing process, as it determines the color and brightness of the light emitted by the tube. The phosphor material is applied to the inner surface of the glass tube using a spinning method. 3. Electrode Insertion: After the phosphor coating is applied, the electrodes are inserted into the glass tube. The electrodes are made of materials that can withstand the high temperatures and pressures inside the refrigerator. 4. Tube Testing: Once the manufacturing process is complete, the refrigerator lamp tube is tested for quality and performance. This ensures that the tube meets the required standards and can be used in refrigeration equipment.

Types of Refrigerator Lamp Tube

There are several types of refrigerator lamp tubes available in the market, each with its unique features and applications. The main types include: 1. Linear Fluorescent Tube: This is the most common type of refrigerator lamp tube, used in various refrigeration equipment, such as refrigerators, freezers, and air conditioners. Linear fluorescent tubes come in different lengths and color temperatures. 2. Circular Fluorescent Tube: Circular fluorescent tubes are used in certain types of refrigeration equipment, such as beverage coolers and undercounter refrigerators. They are available in various diameters and color temperatures. 3. T8 Fluorescent Tube: T8 fluorescent tubes are a popular choice for energy-efficient refrigeration applications. They offer high luminous efficiency and are available in different lengths and color temperatures. 4. T5 Fluorescent Tube: T5 fluorescent tubes are similar to T8 tubes but with a smaller diameter. They are also known for their high energy efficiency and are widely used in refrigeration equipment.

Applications of Refrigerator Lamp Tube
