• Material and Construction Advantages
• PBT plastic body with an aluminum insert supports heat dissipation and structural strength.
• Mechanical lock-cup construction allows the cover to be fixed without glue when the matched components are used.
• Standard A-shape construction is designed for E27 and B22 base applications.
• PC covers are available in milk-white and transparent options with high light transmission.
• Housing color and cover finish can be selected according to the product design.
01 | PC Diffuser Cover
Polycarbonate cover designed for light diffusion and a uniform external appearance.
02 | Main Bulb Casing
Compact housing body providing structural support for internal LED components.
03 | Internal Assembly Structure
Designed to accommodate compatible LED modules and thermal management components.
• Product Quality Comparison
A matched locking structure improves assembly efficiency and provides a cleaner connection between the cover and housing. The aluminum insert is designed to improve heat transfer and mechanical stability compared with lightweight recycled-material alternatives.
• Large- Scale Produciton & High Output Capacity
Our LED bulb housing production facility covers over 10,000 square meters, equipped with 100+ production lines and advanced injection molding machines. With large-scale manufacturing capabilities and efficient production processes, we ensure high-volume output, consistent product quality, and reliable delivery for bulk orders.
