This approach may provide improvements and extend functionalities of traditional or existing lighting devices. Extensions may be provided to the modules on the base board 40 to meet practical needs. Further, the circuit boards may be changed or added according to practical needs.

As shown in FIG. 3, an exemplary camera system consistent with the present disclosure may include a smart terminal, one or more routers, and one or more of the exemplary smart LED lighting devices. The smart LED lighting devices may be distributed and installed in a first group of areas within coverage range of a router 1 in a local area network (LAN). The smart LED lighting devices may provide lighting to a work/living space, and perform video surveillance to the first group of areas, such as area A, area N, etc. Existing LED assembly holes may be used to install these smart LED lighting devices. Further, a plurality of LED lighting devices may be distributed and installed in a second group of areas covered by a router 2 in a different local area network, such as area N+1. The amount of the smart LED lighting devices and area locations may be configured according to specific needs. The smart LED lights may connect to a router in the LAN through the RF antenna 58. In certain embodiments, the routers may be wireless routers.

The routers in different local networks may connect to the Internet. The smart LED lights may use the camera module to film and record, and transmit camera records to the Internet in real-time or upload the camera records to a cloud storage. The smart terminal such as a PC, a smart phone, a laptop computer, a tablet computer or a PDA (personal digital assistant), may connect to the Internet and view the camera data records recorded by the smart LED lighting devices through the Internet in real-time or view the camera data records uploaded in the cloud storage.

The smart LED lighting device consistent with the present disclosure may not only provide common LED lighting functions (such as providing lighting for a work space or a living space), but also perform video surveillance 24/7 under any ambient lighting conditions. When in operation, the smart LED lighting device may collect video and audio data in an acquisition area covered by the camera 53 and the microphones 56, generate camera data records, and transmit the camera records to the Internet in real-time. Users may use the smart terminal to browse the real-time camera records of any smart LED light by installing a corresponding APP (Application).

During day time or when there is plenty of light, the camera 53 may take videos or pictures using lighting provided by the smart LED lighting device or natural light. During night time or when there is insufficient lighting, the camera 53 may take videos or pictures using supplemental infrared light provided by supplemental infrared lighting module 52. The photo sensor 54 may detect light intensity variations and send feedback signals to the circuit board of the smart LED lighting device. During night time or when there is insufficient lighting, the smart LED light may turn off the LED light-emitting module 51 and turn on the infrared LED lighting module 52 to provide supplemental light for the camera 53. The infrared LED lighting module 52 does not emit visible light, therefore when working at night, the camera 53 would not affect users' normal rest, or the visible lighting provided by the smart LED light.

The photo sensor 54 may be configured to automatically detect ambient light intensity. When the ambient visible light becomes insufficient for camera 53 to operate properly, the smart LED lighting device may automatically turn on the infrared LED lighting module 52 to provide supplemental lighting. Further, intensity of the supplemental infrared lighting may be adjusted according to the ambient light intensity, which may save a lot of energy.

In certain embodiments, two smart lighting devices may be place at two locations that are very close to each other. If the photo sensor 54 in either of the two smart lighting devices detects insufficient ambient lighting, the two smart lighting devices may both turn on the infrared LED lighting modules 52 to provide more supplement lighting.

In certain embodiments, the smart light may also include a PIR human detection sensor 55. When sensing a person in a detection range, the smart lighting device may be triggered to save camera data records in the cloud storage. When no one is detected in the detection range, the camera data records may not be saved. This approach may save storage space and reduce demand for storage capacity on the cloud server. In other embodiments, the camera data records may be saved in the cloud storage in real-time. Further, when an intrusion is detected, the smart lighting device may trigger the speaker to sound the alarm and/or increase

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the claims.
