Why do Multi-functional pen-shaped portable work lamp choose aluminum alloy or plastic as the main material of the lamp body?

Aluminum alloy has a lower density and is relatively light, which makes the multifunctional pen-shaped portable work light lighter as a whole, easy to carry and use. At the same time, aluminum alloy also has a higher strength, which can ensure the stability and durability of the lamp body during use. Aluminum alloy is easy to process, form and weld, which allows manufacturers to flexibly manufacture lamp bodies of various shapes and structures according to design requirements to meet different usage scenarios and functional requirements.
After special treatment, the surface of aluminum alloy can form a dense oxide film, which is not only beautiful, but also effectively resists the erosion of moisture, salt and other corrosive substances. In humid or corrosive environments, such as outdoor operations, wet basements or chemical laboratories, aluminum alloy work lights can maintain their appearance and performance for a long time, reducing the cost of repair and replacement due to corrosion. Although the main function of the work light is not to generate a lot of heat, the LED light source will still generate a certain amount of heat during long-term use. As an excellent thermal conductive material, aluminum alloy can quickly disperse the heat generated by the LED light source to the entire lamp body and dissipate it to the environment through air convection or radiation, thereby keeping the LED chip running at a lower operating temperature. This helps to reduce LED light decay, improve luminous efficiency, and significantly extend the service life of the LED light source. Aluminum alloy has high hardness and impact resistance, which can protect the internal electronic components from damage in the event of an accidental fall or collision. This durability makes aluminum alloy work lights particularly suitable for use in occasions that require frequent movement or may be subject to accidental impact.
Plastic materials are lighter than aluminum alloys, which allows pen-shaped work lights to further reduce overall weight and improve portability while maintaining sufficient strength. Although the production of plastic materials involves a certain amount of energy consumption, its production process is less dependent on natural resources than traditional materials such as wood. In addition, with the continuous advancement of plastic recycling technology, more and more plastic waste is converted into new resources and recycled. Therefore, choosing a work light made of plastic is also in line with the environmental protection and sustainable development concepts of modern society. Plastic materials have good plasticity and formability, and can easily achieve designs of various complex shapes and colors. This enables manufacturers to launch a variety of work light products in different styles and styles according to different market demands and user preferences to meet the personalized needs of consumers.
Modern plastic materials have good durability, are not easy to break or fade, and can resist wear and impact during daily use and carrying to a certain extent. The surface of plastic materials is smooth, not easy to accumulate dust, and easy to clean and maintain. Users can easily wipe the surface of the lamp body with a damp cloth or mop to keep it clean and beautiful. Compared with metal materials such as aluminum alloy, the production cost of plastic materials is usually lower, which makes plastic work lights more competitive in price and suitable for consumers with limited budgets.
The multifunctional pen-shaped portable work light chooses aluminum alloy or plastic as the main material of the lamp body because these materials have significant advantages in lightness, processability, corrosion resistance, durability and cost-effectiveness, which can meet the product's requirements for portability, functionality and economy.
