Heronsbill is a light based on the form of a clock. In the daytime, the hour hand is replaced by a beam of light and the minute hand represented as a dot of light. As soon as it gets dark, all the beams of light representing the time interval from that moment until midnight automatically turn on and are extinguished in turn as time passes, gradually dimming the light in the room. After midnight, the beams of light of the corresponding time interval will be turned on one by one gradually brightening the room.
