  • Publication number: 20200270869
    Abstract: The handrail fixing component for supporting a handrail is provided with a casing, a power supply, and a controlling assembly. The casing forms a light transmission hole and at least one detecting hole. The controlling assembly has a circuit board, an illuminating element, a brightness sensor, and a proximity sensor. The illuminating element is mounted on the circuit board and faces toward the light transmission hole. The brightness sensor and the proximity sensor are mounted on the circuit board and face toward the detecting hole. The handrail fixing component may turn on the illuminating element automatically when a creature moves close to the handrail fixing component if the brightness of the environment is not adequate so that the nearby wall and ground are lightened. With the light, people can see the handrail clearly, and find or hold the handrail to avoid falling down.

  • Patent number: 10638576
    Abstract: A control circuit of a lamp has a mode switch, an ambient brightness detector, a human-body movement detector, an illumination device, a wireless communication module, and a microcontroller. The mode switch provides a mode code. The ambient brightness detector outputs an enable signal when brightness of ambient environment is darker than a threshold. The human-body movement detector outputs a trigger signal when detecting a movement event within a detecting area. When the microcontroller receives the enable signal and the trigger signal, the microcontroller activates the illumination device and outputs a wireless control signal having the mode code via the wireless communication module. When the microcontroller receives another wireless control signal via the wireless communication module and determinates that a control code of said another wireless control signal is consistent with the mode code, the microcontroller activates the illumination device.

  • Patent number: 10018278
    Abstract: An automatic water-saving device has a housing, a lower holder, an upper holder, an actuation rod, a blocker, a first resilient member, and multiple positioning balls. The actuation rod, the blocker, the first resilient member, and the positioning balls are disposed between the lower and the upper holders. The lower and upper holders are disposed in the housing. Each of the lower and the upper holders has multiple holes for water flowing. The upper holder further has multiple mouths for water flowing. The automatic water-saving device has the advantage of automatically recovering the water discharge capacity back to small volume after manually adjusting the water discharge capacity to large volume. Hence, the water-saving function of the automatic water-saving device is enhanced and ensured, and the automatic water-saving device is convenient in use.
