Abstract: The present invention relates to the technical field of illumination. Disclosed are a light-emitting panel and a light-emitting device. The light-emitting panel comprises a base substrate, a conductive coil, a first electrode, a light-emitting layer, and a second electrode; the base substrate has a first surface and a second surface which are disposed opposite to each other; the conductive coil is disposed on the first surface of the base substrate, and the conductive coil has a first end and a second end; the first electrode is connected to the first end; the light-emitting layer is disposed on the side of the first electrode away from the base substrate; the second electrode is disposed on the side of the light-emitting layer away from the base substrate, and the second electrode is connected to the second end.

Abstract: Methods, apparatuses, systems, and/or the like are provided. An example method may include installing one or more filter cartridges in a blower device. An example blower device may include a housing defining at least one air inlet. An example filter cartridge may include a first filter cartridge defining a first outlet opening. The first filter cartridge may be configured to slidably engage the blower device to align the first outlet opening with at least a first portion of the at least one air inlet of the blower device in a first installed position. The one or more filter cartridges my include a second filter cartridge. The second filter cartridge may include a second outlet opening. The example method may include aligning the first outlet opening of the first filter cartridge with at least the first portion of the at least one air inlet of the blower device.
