Patent ID: 8836246

Claim:
A photo-controlled light, comprising: 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, wherein 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; and a control switch having a first mode that connects the photosensitive switch unit and the timing switch unit to the electrical power input port and a second mode that connects the electrical power input port to the light emitting unit without passing through the photosensitive switch unit or the timing switch unit so that electricity is transmitted to the light emitting device regardless of the light level detected by the photosensitive switch unit.
