Performance Analysis of LED Light Sources Based on Cardiovascular Disease Treatment

Red light LEDs have shown excellent results from the research of phototherapy for cardiovascular diseases, and the optimal values of light parameters and irradiation time are one of the focuses of their research. Studying the change of LED irradiance and temperature with the irradiation time, and the effect of temperature on irradiance has important reference valued for the phototherapy research of cardiovascular system diseases. Based on the mechanism and application of LED in cardiovascular system diseases, this article tested and analyzed the irradiance and temperature of medical red LED. The experimental results show that as the light time increases, the temperature of the LED increases, and the irradiance decreases. After about 5min, the change rate is small and tends to be stable. Through regression analysis, an approximate relationship curve between the two is obtained.
