The temperature of the skin surface can rise if skin and or anizat ion is in irradiation by hi hli ht LED array s. The st ruct ure of the LED source array s sy stem is presented and a LED array s for analo us acupunct ure is desi ned. The tempera- ture is chan ed accordin t o t he LED parameters such as t he number, irradiation time and luminous intensity of LED . The LED arrays device is used to irradiate the points of human body, actin the same effect on personal or anization as the acupuncture. The sy stem is applied in curin such skin diseases as a e pi ment, skin cancer and f leck. Key words: LED array s; luminous intensity; surface temperature; acupunc
