Patent number: 11168853Abstract: A lamp includes a housing, a lighting device, a plurality of hanging members, a shaft, a plurality of returning members, a plurality of springs, and a power supply. The shaft extends through the housing and the hanging members, such that the hanging members are pivoted connected with the housing. In practice, when the hanging members are pivoted outward from the housing, the returning members are pushed by rotation of the hanging members, and the springs are compressed and contracted by the returning members. At this time, articles are hung on the hanging members, to support the hanging members, thereby preventing the hanging members from being moved back. After the articles are removed from the hanging members, the hanging members are driven and pivoted toward the housing by the returning members and the springs.Type: GrantFiled: January 17, 2020Date of Patent: November 9, 2021Assignee: Dong Guan Jia Sheng Lighting Technology Co., Ltd.

Patent number: 8083369Abstract: An adapter bracket which enables the installation of a door frame or louver into a recessed fixture that sits on a T-bar supported by a ceiling without having to custom design a hinge and latch system to match the original fixture or require the installation of a false frame that lifts the fixture. The brackets slide between the T-bar and the existing fixture. The bracket is also slightly wider than the T-bar opening. The door frame will keep the brackets spaced wide enough to ensure that the assembly would not fall out of the opening. The hinge and latch mechanism for the door frame is built into its end rails and latches onto the bracket to ensure the door frame is supported and held in position.Type: GrantFiled: May 7, 2009Date of Patent: December 27, 2011Assignee: A.L.P.

Patent number: 8070312Abstract: A fluorescent lamp tube catcher formed of bent wire can be detachably engaged with a light fixture, with the central portion of the lamp tube catcher positioned below fluorescent tubes in the light fixture during use. In the event that a fluorescent lamp tube inadvertently becomes loose in the light fixture, the fluorescent lamp tube catcher can stop the loose fluorescent lamp tube from falling. The fluorescent lamp tube catcher can be loosely retained on the light fixture, for example while replacing a fluorescent lamp tube that has failed.Type: GrantFiled: June 12, 2009Date of Patent: December 6, 2011Assignee: Orion Energy Systems, Inc.Inventors: Neal R. Verfuerth, Kenneth J. Wetenkamp, Brandon J. King
