Infrared therapy lamp designs come in all shapes and sizes and they have gained in popularity following the various medical studies that confirmed the benefits of body exposure to the near-infrared (NIR) light. Many commercial products claim they can help with muscle regeneration and pain relief, but those claims are often not supported by the type of NIR and red lamps used in such products. The majority of red and NIR LED lamps on the market today have spectral characteristics that are quickly absorbed and do not allow for deep skin penetration beyond the outer skin layers.
We can help design better infrared therapy lamp products based on the latest scientific data regarding skin and water absorption properties. By tuning the NIR emission using phosphor-converted LEDs (pcLEDs) or laser-excited phosphors (LEPs), the penetration depth of infrared energy can be significantly enhanced. Unlike conventional IR LED or laser products, NIR radiation from pcLEDs and LEPs will be capable of reaching beyond the subcutaneous tissue or deepest layer of the skin and into the muscles. This can be achieved using proprietary solid-state lighting technologies with NIR spectral properties un-matched by any other product on the market. For example, the NIR spectrum can be designed to operate away from the water absorption peaks, as illustrated in the graph below. This will help prevent the NIR energy from being absorbed by the water molecules in the air and skin, so more infrared energy can be available for the deep cells, muscles, and other organs in our body.
More effective infrared therapy lamps can be built for deeper skin penetration
