Patent number: 11589440Abstract: The system of the present application is a switching system for LEDs which prevents breakdown of the system LED driver when switching between LEDs. The system switches between a first LED sting and a second LED string utilizing an LED driver, at least one LED module, a driver input, at least one pair of switching inputs and a switching module such that the first and second LED strings are activated by the switching module at all times, and each of the first and second LED strings operate with a driver output voltage within a voltage-current operating range of the LED driver. This allows the use of different sets of LEDs without requiring duplication of other system components.Type: GrantFiled: December 22, 2021Date of Patent: February 21, 2023Assignee: Kenall Manufacturing CompanyInventor: Patrick Marry

Patent number: 11156339Abstract: A luminaire with uplighting and downlighting capabilities is provided. According to one aspect, the luminaire may include a housing, a light source disposed in the housing, and a lens. The light source may be configured to emit light in a downward direction, and the lens may at least partially cover the light source. An opening may be formed in a top part of the housing and may permit light reflected by an interior surface of the lens to be transmitted in an upward direction from the housing. Optionally, a transparent or translucent cover member may at least partially cover the opening in the top part of the housing.Type: GrantFiled: September 13, 2019Date of Patent: October 26, 2021Assignee: KENALL MANUFACTURING COMPANYInventors: Kevin Dahlen, Brandon Stolte
