This utility model relates to the field of environmental protection cabinet technology, specifically an angle-adjustable ultraviolet disinfection lamp for environmental protection cabinets. It includes a lighting component, which is inclinedly installed on the inner top wall of the environmental protection cabinet. An angle adjustment component, capable of rotating along a vertical axis, is installed on top of the lighting component. This angle adjustment component drives the inclined lighting component to rotate along the vertical axis, thus changing the irradiation angle. An angle adjustment disc, rotating along a horizontal axis, is installed on the back of the lighting component.
