Title:
APPARATUS FOR WARNING SUNBURN WITH ULTRAVIOLET RAYS
Document Type and Number:
Japanese Patent JPH02296119
Kind Code:
A
Abstract:
PURPOSE:To simplify the structure of an apparatus and to reduce cost by providing an photoelectric conversion element having high sensitivity to ultraviolet rays, a battery means, display means, and a warning means. CONSTITUTION:Under the state wherein a switch 108 is opened and a switch 109 is closed, electromotive force is generated across both ends of an element 100 when ultraviolet rays are inputted into the photoelectric conversion element 100. The current flows into a battery or capacitor 102 through a resistor 106. The intensity of the ultraviolet rays is displayed on a display element 104 based on the difference in voltages at both ends of the resistor 106. When the cell voltage of the capacitor 102 becomes the cell voltage corresponding to the specified amount of the ultraviolet rays, warning is issued from a voice generating device 103.
