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. In this angle-adjustable ultraviolet disinfection lamp, the angle adjustment component drives the lighting component to rotate along the vertical axis, and the angle adjustment disc adjusts the tilt of the lighting component along the horizontal axis, forming a multi-dimensional angle adjustment system. This allows the ultraviolet disinfection lamp to irradiate items in different positions and arrangements within the environmental protection cabinet from all directions and multiple angles, completely eliminating the disinfection dead zones present in traditional fixed-installation disinfection lamps.
