Study on Selecting the most Suitable Lighting Application for Medicines in a Dispensary of a Medical Institution

Abstract

Light emitting diodes (LEDs) are widely used in lighting applications, and several types of LEDs are on the market. Firstly, we examined the difference in the degree of color change of various medicines when using LED and fluorescent lighting; the color change of medicines in LED lighting tended to be smaller than in fluorescent lighting, as we reported previously. Next, we examined the difference in the degree of color change of various medicines in three types of LED lighting. As a result, a noticeable degree of color change was observed in the Lasix^® 20-mg Tablet (Tab) and Parlodel^® 2.5-mg Tab. The degree of color change was as follows: bulb color LED lighting < lunch white LED lighting < daylight color LED lighting. The results of our study suggest that one of the most suitable lighting applications for medicines in the dispensary of a medical institution is the bulb color LED lighting.
