Abstract: PURPOSE: A color changing mobile phone case which changes colors depending on ultraviolet intensity using a light sensing pigment, and an ultraviolet block pigment are provided to supply various colorful appearance by changing the colors depending on the intensity of solar cell ultraviolet intensity. CONSTITUTION: A light sensing pigment is used in the entire or some portion of a mobile phone case. As the ration of an ultraviolet blocking pigment is increased, a color changing time is increased in the exposure of a mobile phone case to an ultraviolet ray. If there is not ultraviolet ray, the ultraviolet blocking pigment increases a return reaction speed to an original color of the mobile phone case. Through the non-penetrability properties of a zinc oxide, the big difference occurs in the color of the inner or outer portion color of the mobile phone case.

Abstract: PURPOSE: An ultraviolet light sensor is provided to visually confirm the intensity of solar light using the basic property of a photochromatic pigment which changes colors according to the solar light. CONSTITUTION: An ultraviolet light sensor(10) is composed of a mixture including photochromatic pigment and a base material. The mixture ratio of the photochromatic pigment is between 0.1 and 0.5%, between 1 and 2%, or between 5 and 10%, with respect to the mixture. Ultraviolet ray preventive pigment is added to the mixture of the photochromatic pigment and the base material.
