[0002] Currently, with economic development, indoor lighting, landscape lighting, and architectural lighting are receiving increasing attention and importance. Lighting has evolved from initially focusing solely on brightness to now pursuing aesthetics alongside brightness. Lighting sources and techniques are becoming increasingly diversified. Among these, LED downlights are recessed ceiling lights that project light downwards. Using LEDs as the light source, LED downlights are characterized by being mercury-free, non-toxic, free of electromagnetic pollution and harmful radiation, energy-efficient, environmentally friendly, and having a long lifespan. During nighttime operations, focusing allows the light to achieve both focused and floodlighting functions, thus meeting the needs of both close-range work lighting and long-distance floodlighting.
