Description

Technical Field

[0001] The utility model belongs to the technical field of UV sterilization, in particular to a portable sterilization lamp. Background Art

[0002] Ultraviolet disinfection lamps, also known as ultraviolet germicidal lamps or ultraviolet fluorescent lamps, are lamps that use the bactericidal properties of ultraviolet light for sterilization. They radiate shortwave ultraviolet light with a wavelength of 253.7 nanometers (nm). This wavelength has the strongest bactericidal properties and can be used to disinfect water, air, clothing, and other items.

[0003] Ultraviolet disinfection technology boasts a sterilization efficiency unmatched by other technologies, reaching 99% to 99.9%. The scientific principle behind ultraviolet disinfection is that it primarily acts on the DNA of microorganisms, disrupting their DNA structure and rendering them unable to reproduce and replicate, thereby achieving the desired sterilization and disinfection effect.

[0004] Ultraviolet light sterilization has the advantages of being colorless, odorless, and leaving no chemical residue. However, without proper protection, it can easily cause significant harm to the human body. Exposure to exposed skin can cause redness, swelling, itching, and scaling in mild cases, while severe cases can even lead to cancer and skin tumors. It is also an invisible threat to the eyes, causing inflammation of the conjunctiva and cornea. Long-term exposure can also cause cataracts and other problems. Therefore, extreme caution is required when using ultraviolet light sterilization lamps.

[0005] There are many types of ultraviolet germicidal lamps currently available on the market, but most of them are not convenient to store and carry, and are not suitable for temporary sterilization of tableware and other tools when dining out.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

The light-transmitting plate 13 forms the light-transmitting surface of the housing 10. The base 11, cover 12, and light-transmitting plate 13 collectively define an installation space B. The housing 10 can be shaped like a circle, square, prism, teardrop, or other special-shaped structure, preferably a circle or square, with a diameter or side length ranging from approximately 1 cm to 6 cm.

[0040] The light source module 20 is disposed within the installation space B. The light source module 20 includes a sterilization ultraviolet light source 21, a circuit board 22, and a power supply 23. The circuit board 22 has a first surface 22a and a second surface 22b that are arranged opposite each other. The first surface 22a is disposed corresponding to the light-transmitting plate 13. A plurality of ultraviolet light sources 21 are arranged in an array on the first surface 22a. The light energy emitted by the ultraviolet light sources 21 is emitted from the light-transmitting plate 13. The ultraviolet light source 21 is a UV-LED. The power supply 23 is disposed on the second surface 22b of the circuit board 22 and is electrically connected to the circuit board 22, and is used to power the circuit board 22 and the ultraviolet light source 21.

[0041] The sensor 30 is disposed in the installation space B and is connected to the light source module 20.
