LED lighting system with battery for demand management and emergency lighting
摘要
說明書
The first control circuit can include a wireless radio or wired connection to the Internet, for instance, through a gateway. The first control circuit can be in communication with the charging circuit and the first and second current sources. The first control circuit can include a wired or wireless link to a utility provider (e.g., a power company), and wherein the first control circuit can adjust the ratio of regulated LED currents, ILED/ILED′, in response to data from the utility provider. In some instances, the data can be electricity pricing.
In some embodiments, the LED lighting system can include a light sensor arranged proximal to the light source and coupled to the controller so as to provide signals indicative of a light output of the light source to the control circuit.
In some embodiments, the first control circuit includes a non-transitory tangible computer readable medium comprising instructions for charging and discharging the energy storage device so as to improve a lifetime of the energy storage device while also reducing a current draw of the second current source when electricity pricing is above a threshold or above a running average.
Various objects and advantages and a more complete understanding of the present disclosure are apparent and more readily appreciated by referring to the following detailed description and to the appended claims when taken in conjunction with the accompanying drawings:
