Investiga ion of the Temperature Effect of the LED Therapy Device on Tissue-Mimicking Material

Abstract

Light therapy devices generally use laser light, light-emitting diodes (LEDs), and intense pulsed lights (1PLs) as a source of light energy. LED therapy is a treatment that allows the skin to self-heal as with all other light treatments. The most important feature of the LED therapy application is to activate the skin and shorten the renewal process. In this study, the effects of an LED therapy device within a tissue-mimicking material and on its surface were investigated. Our aim here is to determine how many different lights (such as red, yellow, green, blue, orange and purple) present in the LED therapy device create a temperature effect within the phantom and on the surface of it within 20, 40 and 60 minutes intervals. The temperature measurement was made using a thermocouple placed in a specific area within the agar phantom, which is prepared as a tissue-mimicking material, and by a thermocouple at the surface of it. As a result, it can be said that the LED therapy device in terms of temperature effects is safe and harmless for daily use.
