Description

Technical Field

[0002] Downlights, as a common type of recessed lighting fixture, are widely used in ceiling decoration in commercial, residential, and public spaces. Their core function relies on internal, sophisticated optical components (such as reflectors, lenses, and light source modules) to achieve light efficiency control and directional illumination. However, during long-term use, existing downlights suffer from significant defects in repair and parts replacement processes when optical components are damaged due to high-temperature aging, physical impacts, or electrical faults. This severely impacts efficiency and maintenance costs. Traditional downlights typically integrate their optical components (such as reflectors and lenses) deeply into the lamp body using screws. Repair personnel must use specialized tools (such as Allen wrenches and pry bars) to disassemble multiple layers of the outer casing, heat sink, and driver power supply to access the internal optical components—a cumbersome and time-consuming process.
