  • Light-emitting knob assembly
    Patent number: 9897325
    Abstract: A light-emitting knob assembly is disclosed. The light-emitting knob assembly is disposed on a device for providing a heat source or a fire and includes a knob, a light-sensing plate, an axial bush, a base, and a light generating unit. The knob is utilized for being rotated to control the strength of the heat source or the strength of the fire of the device and driving the light-sensing plate and the axial bush to be rotated relative to the light generating unit. The light generating unit generates different brightnesses and/or different colors of lights to correspondingly display the strength of the heat source or the strength of the fire after the light-sensing plate is rotated. A user can distinguish the strength of the heat source or the strength of the fire via the light-emitting knob assembly from a distance.
