A system to identify incidents associated with streetlight fixtures based on sensor data from one or more smart sensor devices. Each smart sensor device is coupled to a respective streetlight fixture and captures data from one or more sensors. The data from a single smart sensor device or a plurality of smart sensor devices is aggregated to generate a current data signature of the one or more smart sensor devices. The current data signature is compared to a plurality of known signatures to determine if an incident associated with a streetlight fixture has occurred. Such incidents can include a failed light source, a failing light source, a weather incident, a geologic incident, etc. Depending on the type of incident an instruction is sent to the one or more smart sensor devices to perform one or more responsive actions.

A lighting system having multiple light sources is provided, which includes a first light source and a second light source. The first light source includes a first control module, a second memory module, a first lighting-emitting module and a first detection module. The second light source includes a second control module. When the first light source and the second light source are electrically connected to a power source, the first control module and the second control module turn off the first light source and the second light source respectively. The first control module reads the data of the first memory module of the first light source to determine whether the first light source malfunctions, and turns on the first light-emitting module when the first control module determines that the first light source does not malfunction. Then, the first detection module keeps detecting whether the first light source malfunctions.

In light source device 60, which is disposed in a component mounter for holding a component by using mounting head 24 and mounting a held component that is the component that has been held on a board, and used when the held component is imaged by imaging device 50, and includes multiple light sources 62; and controller 64 configured to control the multiple light sources, when one or more of the multiple light sources do not emit light, the controller executes light intensity enhancement processing of enhancing an intensity of light emitted by any of the other light sources among the multiple light sources. By executing the light intensity enhancement processing, in a case where any of the multiple light sources fails, it is possible to reduce a possibility that a component mounting operation by the component mounter is stopped.

A lighting system with illumination-balancing function is provided, which includes a plurality of lighting devices distributed over a lighting zone. Each of the lighting devices includes a control module and a light-emitting module. The light-emitting module is connected to the control module. When the light-emitting module malfunctions, the control module transmits a malfunctioning signal to the other lighting devices not malfunctioning, such that the brightness of each of the lighting devices, not malfunctioning and adjacent to the lighting device malfunctioning, increases so as to make the illumination of the lighting zone be substantially equal to a predetermined value.

Example embodiments relate to systems for checking a luminaire status and methods thereof. One embodiment includes a method for checking a status of a luminaire using a mobile terminal in a vicinity of the luminaire. The mobile terminal includes a sensing means, a memory, and a communication means. The method includes obtaining, by the mobile terminal, an identifier of the luminaire. The method also includes determining, based on the obtained identifier of the luminaire, a measure of the status of the luminaire to be acquired. Additionally, the method includes acquiring, by the sensing means of the mobile terminal, the measure of the luminaire status. Further, the method includes storing, in the memory of the mobile terminal, data about the acquired measure of the luminaire status. The data is associated to the identifier of the luminaire.

Emergency light devices, systems and methods that provide instant light in a power outage or other situations. One or more sensors monitor the flow of electricity, and when the flow of electricity is stopped or no longer present, an emergency light device power monitoring device instantly communicates via wireless communication technology to emergency light device(s) to instantly turn on the emergency light device(s). The emergency light device(s) can be a portable and/or permanent unit of varying shapes and sizes, and can be attached to any object, or may stand alone, with some or all of its parts being replaceable, interchangeable, or upgradeable.

A control method includes determining a first control signal of a first control unit, determining a second control signal of a second control unit, and controlling a light effect of the illumination device according to a control rule, the first control signal, and the second control signal. The first control signal is used to control an illumination device to generate a first light effect. The second control signal is used to control the illumination device to generate a second light effect.
