  • Patent number: 9351374
    Abstract: A photo-controlled light includes an electrical power input port configured to receive electrical power, a light emitting unit that is connected to the electrical power input port and a photosensitive timer module that connects the light emitting unit to the electrical power input port. The photosensitive timer module includes a photosensitive switch unit including a photosensitive element that is configured to detect a light level that satisfies a luminosity threshold value, a timing switch unit coupled to the photosensitive switch unit that is configured to only connect the electrical power input port to the light emitting unit for a conduction time frame responsive to the photosensitive switch unit detecting that the light level is less than the luminosity threshold value so that the photosensitive timer module transmits electricity during the conduction time frame when the luminosity detected by the photosensitive element is less than the luminosity threshold value.
