**7. The future of LED therapy**

The application of high brightness LEDs in human tissue has been growing every day. Several scientific institutions have explored this theme. Many researches are underway on the use of therapy with the LED in order to improve their application and to determine if there are other applications which may be used. The therapy is applied within the visible light spectrum and each color has its application and its therapeutic purpose.

The red color that is in a range of 600-700 nanometers, is effective in human tissues and shows excellent results in wounds and sores. The higher wavelengths, including infrared, are more sharp and can reach the bone. Studies also suggest that the spectrum between 400 to 500 nanometers, in the range of blue color, can be effective in the treatment of skin disorders, including acne, stretch marks, cellulite, skin blemishes and scarring.

Probably in the next few years, LED Therapy will be the main treatment for wounds, such as post-surgical wounds and unhealed as diabetic ulcers. Scientists seek to test the technology of LED Therapy in other clinical situations, such as spinal cord injuries and treatment of Parkinson's disease, cerebrovascular accidents, brain tumors and regenera‐ tion of tissues and organs [17].

With the advancement and development of new applications of LEDs in health, manufacturers of these devices will increasingly improve these devices that every day demonstrate its usefulness and its application to human health.
