Patent number: 11719400Abstract: Electrical devices with lights having onboard secondary power supplies are configured with synchronizable zone-based operation and/or color selectable modes. The electrical devices can be power receptacles and can be connected to a line input of a power circuit of a power grid and can also have the onboard secondary (emergency power) power supplies. The devices are configured so that respective lights can automatically illuminate upon motion detection in a zone and/or upon a disruption to the power circuit or to a powered state of a particular electrical device. The devices can be configured to allow a user to select different color or color temperatures using a color selection circuit.Type: GrantFiled: December 14, 2021Date of Patent: August 8, 2023Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Abdulkabir O. Dansalami, Saivaraprasad Murahari, Kevin Zhong, Huafei Huang, Sophia Zhang
