All-metal microstructure sound absorption plate and sound absorption lamp thereof
By incorporating the sound-collecting recesses and penetrating slits in the all-metal microstructure sound-absorbing panel, combined with the Z-shaped plate connecting the light trough, the problem of insufficient low-frequency sound absorption and safety hazards of fiber filling materials in existing sound-absorbing lamps is solved. This achieves wide-band sound absorption and efficient heat dissipation in an all-metal structure, improving the performance of the lamps.

AI Technical Summary
Existing sound-absorbing lamps have poor sound absorption in the low and mid-frequency range, and their reliance on fiber filling materials poses safety hazards and presents processing complexities, making it difficult to achieve the design freedom and efficient heat dissipation of an all-metal structure.
The all-metal microstructure sound-absorbing panel uses a funnel-shaped sound wave converging structure formed by sound-collecting recesses and penetrating slits. Combined with the Z-shaped plate connecting the light trough, it achieves acoustic separation and efficient heat dissipation, eliminating the safety hazards of fiber filling materials.
It improves the sound absorption performance in the mid and low frequencies, reduces surface sound reflection, achieves wide-band sound absorption in an all-metal structure, and combines acoustic separation and efficient heat dissipation functions, thus extending the service life of the lamps.
