BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable ultraviolet light meter, and more particularly, to an ultraviolet light meter implemented to prevent dermatological diseases caused by ultraviolet light by allowing a person to easily carry out an ultraviolet index anytime, anywhere.

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 to 400 nm is not absorbed by the ozone layer. Most of ultraviolet-B with a wavelength of about 280 to 320 nm is absorbed by the ozone layer, but some reach the ground surface. UV-C, with a wavelength of around 100-280 nm, is completely absorbed by the ozone layer.

Ultraviolet rays are bactericidal and produce vitamin D when irradiated into the human body, but UV-A and especially UV-B penetrate the surface of the skin, causing burns and increasing the incidence of skin cancer and cataracts. Can be. Due to the depletion of the ozone layer and the associated increase in solar ultraviolet rays reaching the surface, human risks are associated with personal habits such as the degree of sun exposure.

For the purpose of sharing information on the extent to which solar ultraviolet light affects the human body, the use of a simple and universally applicable solar UV index is recommended worldwide. The UV Index is a forecast, not a measure, that tells the extent of sunbathing and was developed to call attention to UV rays. Originally, the Index was developed by the US Environmental Protection Agency (EPA) and the National Oceanic and Atmospheric Administration (NOAA). ), The United States Meteorological Agency (NWS), and the Center for Defense Prevention (CDC). To date, no country other than the United States has forecasts, but only forecasts using data provided by the United States.

The UV index refers to the amount of radiation of the ultraviolet-B (UVB) region that reaches the surface at the midnight time at which the solar altitude is the maximum. The UV index is divided into 10 grades. When the risk is very high. The UV Index provides information about human skin risks that are expected to be overexposure to the sun and indicates how much care should be taken when outdoors.

The UV index can be classified mainly into very low (0 ~ 2.9), low (3 ~ 4.9), moderate (5 ~ 6.9), high (7 ~ 8.9), and very high (more than 9). The UV index is at least 1 hour 50 minutes at very low, at least 1 hour 40 minutes at low, at least 1 hour at normal, at least 40 minutes at high, and at least 30 minutes at high. 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 Korea 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 Korea Meteorological Agency is a preliminary forecast of the UV index, but because it does not provide information about the ultraviolet rays that change over time from time to time, it can not cope with the fluctuation of the ultraviolet rays, regionally, for example, Gangwon-do region, Seoul region, etc. It provides only approximate information that covers a large area, thus reducing accuracy when applied in real life.
