The present invention is generally related to display devices, and more particular to a display device with an ultraviolet germicidal lamp fixed to its rim.
A display device is the most important output device for a computer, regardless of whether the computer is for industrial, commercial, or home application.
Republic of China, Taiwan, Patent No. M387206 teaches a lamp for a display device, and the lamp includes a light member, a positioning member, and a rack member. The positioning member fixes the light member to the display device. The light member may be a traditional light source or a light source using LED or OLED. The positioning member includes a base, clamp pieces, gears, and a lever. The level engages the gears, which in turn drives the clamp pieces, so that the positioning member is reliably clamped to a rim of the display device.
The positioning member of the lamp is rather complicated. On the other hand, the global outbreak of pandemics such as SARS in the past and COVID-19 recently prompts people to realize that display devices, especially when they are used by different persons, could be a hotbed for germs and viruses. There is a need for the light member of the above-described lamps on display devices to provide sterilization.
To achieve the above objectives, the present invention provides a display device with an ultraviolet (UV) germicidal lamp, which includes a display device having a circumferential rim, an UV germicidal lamp, a power electrically connected to the UV germicidal lamp, a control circuit electrically connected to the UV germicidal lamp, and a fixture member detachably fixing the UV germicidal lamp to the circumferential rim of the display device. The fixture member includes a base, a first clamp piece, and a second clamp piece. The base is joined to the UV germicidal lamp. The first clamp piece and the second clamp piece are mounted at interval on the base, thereby forming a clamp interval in between. An elastic element is provided between the second clamp piece and the base for forcing the second clamp piece slidably towards the first clamp piece.
Preferably, the first clamp piece is immediately stacked on the second clamp piece.
Preferably, two troughs are provided respectively and oppositely along two opposing lateral inner walls of the base, and wo lateral edges of the first clamp piece and two lateral edges of the second clamp piece are respectively and slidably embedded in the troughs.
Preferably, a connector is provided along a side of the base.
Preferably, the display device with UV germicidal lamp further includes a signal receiver electrically connected to the control circuit for receiving a wireless signal from a mobile device.
Preferably, a sensor is electrically connected to the control circuit for detecting the proximity of a human body.
As described above, by sliding the first clamp piece relative to the second clamp piece to adjust the clamp interval, the UV germicidal lamp may be reliably clamped to the circumferential rim of the display device.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

The display device 1 may be a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED) display, or other similar display device. The display device 1 has a circumferential rim 11.
The UV germicidal lamp 2 is mounted on the circumferential rim 11 of the display device 1. The UV germicidal lamp 2 is configured with a ON/OFF switch 21 to an end. The ON/OFF switch 21 is for turning on or off the UV germicidal lamp 2. A first press of the ON/OFF switch 21 turns on the UV germicidal lamp 2 and the UV germicidal lamp 2 produces an ultra-violet (UV) light. After the UV germicidal lamp 2 is turned on and the UV light has performed sterilization for a period of time, the UV germicidal lamp 2 would be automatically turned off. Alternatively, while the UV germicidal lamp 2 is turned on, pressing the ON/OFF switch 21 may also turn off the UV germicidal lamp 2 to stop the illumination by the UV light. The UV germicidal lamp 2 may be configured with an indicator member to inform whether the sterilization is completed. The indicator member may be an indicator lamp, a buzzer, or an indicator display. The UV germicidal lamp 2 may be an UV lamp, a metal halide lamp, a high intensity discharge (HID) lamp, a mercury vapor lamp, or a fluorescent lamp. The UV lamp may be an UVA, UVB, or UVC lamp. An UV light has a bandwidth between 10 nm and 400 nm. UVA has a bandwidth between 320 and 400 nm, UVB is between 280 and 320 nm, and UVC between 100 and 280 nm. An ordinary UV light has a bandwidth between 200 nm and 280 nm.
The power 4 may be an external power source. The power 4 is electrically connected to the UV germicidal lamp 2. The control circuit 5 is configured within the fixture member 3. The control circuit 5 is electrically connected to the UV germicidal lamp 2 for turning on and off the UV germicidal lamp 2, the intensity of the UV germicidal lamp 2, and the duration of lighting.

More specifically, two troughs 34 are provided respectively and oppositely along two opposing lateral inner walls of the base 31. Two lateral edges of the first clamp piece 32, and those of the second clamp piece 33, are respectively embedded in the troughs 34. The first clamp piece 32 is stacked immediately on the second clamp piece 33. The first clamp piece 32 and the second clamp piece 33 may be L-shaped, where the first clamp piece 32 includes at least a first vertical piece 321 and a first lateral piece (not numbered), and the second clamp piece 33 includes a second lateral piece 332 and at least a second vertical piece 331. The first and second vertical pieces 321 and 331 are extended upward from the first and second lateral pieces respectively.
