An LED high-bay light comprises a channel-shaped heat-dissipating lamp body, a light engine assembly, and a power supply box assembly. The channel-shaped heat-dissipating lamp body includes a hollow annular connecting portion and a heat-dissipating portion disposed around the periphery of the connecting portion. The light engine assembly is disposed within the channel-shaped heat-dissipating lamp body and connected to the connecting portion via thumbscrews. The power supply box assembly is disposed outside the channel-shaped heat-dissipating lamp body and detachably connected to the side of the connecting portion facing away from the light engine assembly. The power supply box assembly has opposite first and second sides; the first side is hinged to the connecting portion, while the second side is connected to the connecting portion via thumbscrews.
A plurality of heat-dissipating fins are provided on the side of the heat sink facing away from the light source board. A waterproof sealing ring is positioned between the lens and the heat sink; the outer periphery of the lens is provided with a waterproof retaining slot, and the waterproof sealing ring is seated within this slot.
The light further includes a waterproof sensor base and a sensor. Mounting holes are provided at the centers of the heat sink, the light source board, and the lens; the waterproof sensor base is mounted within the mounting hole of the heat sink, and the sensor passes through the mounting holes of the light source board and the lens to be installed onto the waterproof sensor base. By utilizing the collaborative operation of a millimeter-wave radar and an infrared sensor, the light can not only accurately detect the movement of personnel and vehicles but also dynamically adjust lighting strategies based on ambient temperature and dust concentration.
