Description

Mobile phone equipped with an apparatus for detecting UV}

The present invention relates to an ultraviolet sensing device, and more particularly to a mobile phone equipped with an ultraviolet sensing device.

Ultraviolet rays are included in various light sources, including sunlight. Ultraviolet radiation, which has a shorter wavelength than visible blue or violet light, is mainly classified into three types: ultraviolet-A (UVA), ultraviolet-B (UVB), and ultraviolet-C (UVC). Ultraviolet-A with a wavelength of about 320-400 nm is not absorbed by the ozone layer. Ultraviolet-B with a wavelength of about 280-320 nm is mostly absorbed by the ozone layer, but some reach the ground surface. Ultraviolet-C, with a wavelength of around 100-280 nm, is completely absorbed by the ozone layer.

Ultraviolet rays are bactericidal and can produce vitamin D when irradiated by the human body, but UV-A and especially UV-B penetrate the surface of the skin, causing burns and increasing the frequency of skin cancer and cataracts. Can cause. Due to the depletion of the ozone layer and the associated increase in solar ultraviolet rays reaching the surface, the risk to humans It is related to personal habits, such as the degree of exposure to sheep.

The use of a simple and universally applicable solar UV index around the world is recommended for the purpose of sharing information on the extent to which solar ultraviolet light affects the human body.

The UV index is the amount of radiation in the UV-B (UV-B) region that reaches the Earth's midnight at the highest altitude, divided into 10 classes, with 0 being the lowest risk at exposure and over 9 being excessive. This means that the risk is very high when exposed. The UV Index provides information on human skin risks that are expected from overexposure to the sun and indicates how much care should be taken when outdoors.

The UV index can be classified into very low (0 ~ 2.9), low (3 ~ 4.9), normal (5 ~ 6.9), high (7 ~ 8.9), and very high (more than 9). UV index is very low at 1 hour 50 minutes, low at 1 hour 40 minutes, normal at least 1 hour, high at 40 minutes and at very high 30 minutes Exposure can also cause red spots on your skin. The degree of red staining according to the exposure time may vary depending on the skin constitution as shown in FIG. 1.

Because the stratospheric ozone amount and cloud have a great influence on the UV intensity reaching the ground, the Meteorological Administration forecasts the UV index by considering the stratospheric ozone amount and weather changes. The Meteorological Agency's UV index forecast is announced twice a day. The 06 o'clock announcement is the same day, and the 18:00 announcement shows the UV index of the next day.

The announcement by the Meteorological Agency may be a preliminary estimate of the UV index. Since it does not provide information about the ultraviolet rays that vary depending on the liver from time to time, it cannot cope with the fluctuation of the ultraviolet rays, and only provides rough information that covers a wide area such as Gangwon-do region and Seoul region. It is less accurate when applied.

In addition, ultraviolet rays are also present in the interior of a car because they pass through glass, and even when the day is cloudy, unlike the average person's perception, UV rays are measured most strongly from 11 am to 3 pm in April to October. Since it is neither visible nor hot, it cannot be detected by humans, so an ultraviolet sensing device is necessary to know the presence and intensity of ultraviolet rays.

By the way, the conventional ultraviolet detection device is often used mainly in the laboratory, school, factory, etc. as the experimental equipment or production equipment for producing a sterilization apparatus using mainly ultraviolet light. In addition, there is a problem that the volume is difficult to carry and difficult to measure ultraviolet rays when individual users need.

Patent No. 158956 has registered an invention for attaching an ultraviolet sensing device to a wrist watch to warn of the danger of ultraviolet rays by a buzzer signal due to the necessity of a portable ultraviolet sensing device. However, the problem lies in simply providing a buzzer signal. .

In other words, this patent is notified by the alarm sound only by distinguishing whether the amount of ultraviolet light is higher or lower than the reference value centering around the standard, and as described above can not be accurately informed according to the various ultraviolet reference values, so the user knows exactly the safe time for outdoor activities There is no problem.

In addition, the place where the actual user is exposed to ultraviolet light for a long time is a lot of places where the surroundings are noisy compared to the buzzer signal, such as a baseball field, a soccer field, a beach, an outdoor pool, and the like. In addition, communication etiquette is important, and the use of the buzzer signal is prohibited. Considering the trend of etiquette as a culture, the use of information reception through buzzer signals will be more limited.

On the other hand, there is a 'vehicle equipped with an ultraviolet ray detection device' filed and registered by the applicant of the present application, but this is only suitable when there is a problem in that there is a limit to the actual application.

The present invention has been made to solve the problems appearing in the prior art as described above, it is an object of the present invention to provide a device that can be delivered to the user in the manner of detecting the ultraviolet light signal.

Another object of the present invention is to provide a device that can inform the user by subdividing the information on the detected ultraviolet rays.
