Illumination devices are described. In one embodiment, an illumination device includes a light configured to be coupled to eyewear or a mask, such as a surgical loupe or a dental loupe. The illumination device also includes a battery configured to be coupled to the light. The light and the battery may be connected by a light connector and a battery connector. The illumination device also includes a battery coupling device coupled to the battery. The battery coupling device may be configured to couple the battery to a body part of a user. For example, the battery coupling device may include arms that wrap around a back of a head of a user, and grip or hold the sides of a head of a user.

The present invention discloses a working light, comprising a base, an illumination member and a switch control, a battery is arranged inside said base to supply power to said illumination member, said base is connected to said illumination member by a connection portion, said base and said illumination member are respectively connected to said connection portion by the same connection structures. By this arrangement, said base cannot be connected to said illumination member directly, users would not make mounting errors in use. In a preferred embodiment of the present invention, said connection portion is a serpentine hose or a joint-sleeve, wherein the serpentine hose includes a corrugated pipe and an internal star-shaped pipe, a wire and an iron wire which are arranged inside the corrugated pipe, this serpentine hose couples stiffness with toughness, after adjusting the curved shape, it is not easily deformed. The working light in the present invention overcomes several problems of the current portable illumination light and have a wide range of application, which can satisfy different requirements of users.

An ultraviolet sterilization and plant growth system can be mounted to an air duct to sterilize the air and then selectively removed and used in a portable mode to sterilize surfaces or enhance plant growth. The system includes a housing, a heatsink element, an array of ultraviolet light-emitting diodes (LEDs) to generate directional beams of ultraviolet radiation, and an electronic driver to control the LEDs. One or more power interfaces allow for operation in AC mode when connected to a power receptacle or in DC mode when powered by a portable source. In addition to its sterilization capabilities, the system incorporates tunable LEDs and programmable light recipes designed to support plant health and growth. These include specific light frequencies for vegetative growth, flowering, and pest control, making the system a versatile solution for both sterilization and horticultural applications.
