Refrigerator lamp tube, also known as refrigerator light tube, is an important component in modern refrigeration equipment. It plays a crucial role in the lighting system of refrigerators, providing illumination for the interior space. This article will introduce the industry of refrigerator lamp tubes, including their types, manufacturing process, application, and market trends.

Types of Refrigerator Lamp Tubes Refrigerator lamp tubes can be divided into two main types: fluorescent tubes and LED tubes. Fluorescent tubes are widely used in the past due to their low cost and energy efficiency. However, with the development of technology, LED tubes have gradually replaced them due to their longer lifespan, lower energy consumption, and higher brightness.

Fluorescent Tubes Fluorescent tubes are made of glass tubes, filled with inert gas and a small amount of mercury vapor. When an electric current passes through the tube, the mercury vapor emits ultraviolet light, which then excites the phosphor coating on the inner surface of the tube to emit visible light. The length and diameter of the tube can be customized according to the specific requirements of the refrigerator.

LED Tubes LED tubes are made of semiconductor materials, which can convert electrical energy into light energy directly. Compared with fluorescent tubes, LED tubes have the following advantages: 1. Long lifespan: The lifespan of LED tubes can reach 50,000 hours or even longer, which is 5-10 times longer than that of fluorescent tubes. 2. Low energy consumption: The energy consumption of LED tubes is only 1/5-1/10 of that of fluorescent tubes, which can save a lot of electricity. 3. High brightness: LED tubes have higher brightness and better color rendering, which can provide a more comfortable and clear lighting environment. 4. Environmental protection: LED tubes do not contain mercury and other harmful substances, which is more environmentally friendly.

Manufacturing Process The manufacturing process of refrigerator lamp tubes mainly includes the following steps: 1. Raw material preparation: Select high-quality glass, phosphor, and other raw materials. 2. Tube forming: Use a glass blowing machine to form the required shape and size of the tube. 3. Phosphor coating: Apply phosphor coating on the inner surface of the tube to improve the light-emitting efficiency. 4. Filling and sealing: Fill the tube with inert gas and mercury vapor, and then seal the tube to prevent gas leakage. 5. Aging and testing: After the tube is produced, it needs to be aged and tested to ensure its quality.

Application Refrigerator lamp tubes are mainly used in the lighting system of refrigerators, freezers, and other refrigeration equipment. In addition, they can also be used in other fields such as lighting, medical equipment, and automotive lighting.

Market Trends With the continuous development of the refrigerator industry, the demand for refrigerator lamp tubes is increasing. At the same time, the market competition is also increasingly fierce. The following are the main market trends: 1. The demand for LED tubes is growing: As the technology of LED tubes continues to improve, their market share is gradually increasing. 2. The trend of energy saving and environmental protection: The market demand for energy-saving and environmentally friendly refrigerator lamp tubes is increasing. 3. The development of intelligent lighting: The integration of refrigerator lamp tubes and intelligent technology is becoming more and more popular. In conclusion, refrigerator lamp tubes are an important component in modern refrigeration equipment. With the continuous development of technology and market demand, the industry of refrigerator lamp tubes will continue to grow. Enterprises should pay attention to technological innovation, product quality, and market trends to seize the market opportunities and achieve sustainable development.
