Publication number: 20230380031Abstract: A LED based lighting apparatus is disclosed. The light engine used in the lighting apparatus may use printed circuit board and have a plurality of LED groups that are independently controllable by a control unit. The power supply input and return paths connected to each LED group may be implemented on different layers to allow a compact footprint that may be used with traditional fluorescent encasements with relatively little modification. The LEDs may comprise a subset of LEDs having a first colour and a subset of LEDs having a second colour different from said first colour intertwined on the light engine.Type: ApplicationFiled: March 26, 2023Publication date: November 23, 2023Applicant: ARKALUMEN INC.Inventor: Gerald Edward BRIGGS

Patent number: 11654394Abstract: A method and installation for removing a gas from a flow of a gas mixture. A first liquid (82) is introduced in the flow (106) for evaporative cooling and saturation of the gas mixture. Small droplets of a second liquid (84) are provided which are capable of adsorbing and dissolving said gas and of a size small enough not to be sedimented by gravitation and big enough to be centrifugally separated. The small droplets are sprayed into the flow for adsorbing and dissolving said gas into the droplets, and the small droplets are centrifugally separated from the flow.Type: GrantFiled: March 4, 2020Date of Patent: May 23, 2023Assignee: ARKALUMEN INC.Inventors: Claes Inge, Peter Franzén, Carl Petrus Häggmark

Publication number: 20220030686Abstract: Control apparatus and system for controlling an output of a constant current driver are disclosed. A control apparatus is coupled between a constant current driver and a load, such as a lighting module, in order to add functionality to the overall system. The control apparatus is powered by the constant current driver and may control the dimming of the constant current driver by controlling the 0-10V dim input into the driver. The control apparatus may comprise one or more switching elements between the constant current driver and the load to allow for mixing of groups of LEDs of various colors or color temperatures. The control apparatus may include a buffer load to mitigate negative impacts of turning on the lighting module after a period of deactivation. The control apparatus can also be adapted to operate as a dim-to-warm module within a lighting apparatus.Type: ApplicationFiled: August 2, 2021Publication date: January 27, 2022Applicant: ARKALUMEN INC.Inventors: Sean MacLean Murray, Yan Vermette, Gerald Edward Briggs, Julien Girard

Patent number: 10757784Abstract: A lighting apparatus that may comprise a voltage converter operable to supply a current to at least two LED channels coupled between a high voltage rail and a low voltage rail coupled to the voltage converter output is disclosed. The LED channels may be operated to selectively allow a current to flow through them. The lighting apparatus may also have a control module operable to control the total current from the voltage converter and the current through each of the LED channels. The control module may also be operable to set the respective control signals to maintain a constant total current from the voltage converter while permitting aspects of the light output including, the intensity, color, and color temperature to be set and varied. Additionally, the control module may be operable to synchronize the various control signals, obtain a representative sample of the current through the voltage converter, and operate in different modes.Type: GrantFiled: February 20, 2017Date of Patent: August 25, 2020Assignee: ARKALUMEN INC.Inventor: Gerald Edward Briggs
