ULTRAVIOLET LIGHT IRRADIATION DEVICE AND ULTRAVIOLET LIGHT IRRADIATION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240024524 titled 'ULTRAVIOLET LIGHT IRRADIATION DEVICE AND ULTRAVIOLET LIGHT IRRADIATION METHOD
Simplified Explanation
The ultraviolet light irradiation device described in the patent application consists of a light source section that emits ultraviolet light within a specific wavelength range, a controller that controls the lighting of the light source section, and a distance sensor that measures the distance between the light emission surface and an object facing it. The controller has multiple lighting operation modes, each corresponding to a specific separation distance and emitting a different amount of ultraviolet light. The controller switches between these modes based on signals from the distance sensor.
- The device includes a light source section emitting ultraviolet light within the range of 190 nm to 235 nm.
- A controller is responsible for controlling the lighting of the light source section.
- A distance sensor measures the separation distance between the light emission surface and an object facing it.
- The controller has multiple lighting operation modes, each corresponding to a specific separation distance.
- Each lighting operation mode emits a different amount of ultraviolet light.
- The controller switches between lighting operation modes based on signals from the distance sensor.
Potential Applications:
- Sterilization: The device can be used for sterilizing surfaces, objects, or even air by emitting controlled amounts of ultraviolet light.
- Disinfection: It can be utilized in medical settings, laboratories, or public spaces to disinfect equipment, tools, or surfaces.
- Water Treatment: The device can be employed in water treatment facilities to eliminate harmful microorganisms.
- Food Processing: It can be used in food processing plants to sanitize equipment and surfaces, ensuring food safety.
- Air Purification: The device can help in purifying the air by neutralizing airborne pathogens and allergens.
Problems Solved:
- Inefficient sterilization: The device addresses the issue of inefficient sterilization by providing multiple lighting operation modes that emit different amounts of ultraviolet light based on the separation distance.
- Inconsistent disinfection: By controlling the amount of ultraviolet light emitted, the device ensures consistent and effective disinfection across different separation distances.
- Lack of flexibility: The multiple lighting operation modes allow the device to adapt to various scenarios and distances, providing flexibility in its application.
Benefits:
- Enhanced sterilization and disinfection: The device's ability to emit different amounts of ultraviolet light based on the separation distance ensures more effective sterilization and disinfection.
- Improved safety: By controlling the amount of ultraviolet light emitted, the device minimizes the risk of overexposure and potential harm to humans or sensitive materials.
- Increased efficiency: The device's ability to adapt to different separation distances optimizes the use of ultraviolet light, making the sterilization and disinfection process more efficient.
- Versatility: The device can be used in various applications, such as sterilization, disinfection, water treatment, food processing, and air purification.
