US 12,607,340 B1 · LED panel light

Abstract

LED panel light includes housing, bracket, and illumination assembly. Housing comprises heat sink base with multiple fins, outer shell, inner shell, and center shell. Inner shell mounts on heat sink base, outer shell encompasses inner shell, and they jointly define mounting cavity. Center shell extends through inner shell connecting to heat sink base, wherein inner wall of center shell and heat sink base jointly define light-transmitting chamber. Illumination assembly comprises control board within mounting cavity; LED board, light diffusion sheet, and light-transmitting tube within light-transmitting chamber. LED board thermally couples to heat sink base, and light diffusion sheet attaches to light-transmitting tube's inner wall. Thermal coupling between heat sink base and LED board enables rapid heat dissipation for extended operation periods. Inner shell specifically accommodates control board, isolating it from other components, enhancing sealing performance and moisture resistance, thereby reducing malfunction probability when LED panel light operates in humid environments.
