  • design tradeoffs for a light-based temporary hair removal device for home-use may involve balancing the efficiency of the optical subsystem and ability to generate optical radiation of sufficient characteristics to treat various skin types versus cost of optical components and associated power, cooling, filtering, weight, and size requirements.
  • Device costs generally increase with optical components exhibiting relatively high efficiencies, light sources providing optical radiation at preferred wavelengths with reduced filtering requirements, power components requiring greater output power and stringent pulse forming capabilities, effective techniques for high temperature cooling applications (liquid cooling being more complex and expensive than air cooling), etc.
  • an exemplary implementation of the disclosed technology can be used to develop such safe, effective, comfortable, and low cost hair growth management/removal devices by a) employing a relatively low-efficiency, low cost, multi-wavelength light source suitable for treating multiple skin and hair types, b) increasing the efficiency of the light source using light recycling techniques to enhance its brightness (i.e., spectral radiance) and thereby reduce power and filter requirements, c) optionally converting optical radiation exhibiting undesired wavelengths into preferred wavelengths (while, preferably, integrating the optical radiation such that it exhibits a substantially uniform light distribution at substantially the same time as the wavelength conversion), d) using a skin contact component of the device for dual purposes—facilitating the conveyance of optical radiation and concurrently inhibiting a user's pain sensation during the dermatologic treatment, e) providing multiple operating modes to cover spot treatments or large area treatments, and/or f) providing a mechanism that both facilitates movement of the device over a skin treatment surface by reducing the coefficient of friction at the skin-device interface
  • the light source used in this illustrative embodiment is a flashlamp (e.g., xenon, krypton or the like) exhibiting an efficiency in wavelengths of interest of, for example, between about 10-20% and emitting optical radiation having wavelengths at least in the near infrared portion of the electromagnetic spectrum suitable for hair growth management/removal dermatologic treatments.
  • the flashlamp is at least partially surrounded by multiple reflective coatings that are designed to reflect optical radiation exhibiting wavelengths that are not desired (e.g., ultraviolet) for the dermatologic treatment back to the plasma of the flashlamp while allowing preferred wavelengths (e.g., near infrared) to pass substantially unimpeded.
  • the reflective coatings provide a mechanism that both reflectively filters out a substantial amount of unwanted wavelengths and recycles these unwanted wavelengths so that they are superposed on the directly-emitted optical radiation to increase the brightness (spectral radiance) of the optical radiation, thereby resulting in an improved efficiency in the flashlamp without providing additional electrical current to the flashlamp.
  • This technique of superposing unwanted radiation back onto the directly-emitted optical radiation emitted by the light source preferably results in a flashlamp efficiency in the wavelengths of interest that significantly exceeds 20%.
  • the improved efficiency of the light source in the wavelengths of interest improves the efficacy of the device in performing the dermatologic treatment and reduces the size and capacity requirements of the power supply that is used to energize the flashlamp—resulting in reduced cost and size in the overall dermatologic treatment device.

  • the thermally conductive material 908 may also include wavelength conversion material (such as quantum dots) to convert undesired wavelengths emitted by the light source 902 into preferred wavelengths while concurrently using at least some of any optical radiation backscattered from such wavelength conversion material to further enhance the brightness of the light source 902 .
  • the replacement procedure may be initiated, for example, in the event that different skin types are to be treated (in which it may be desirable to insert optical components that are optimized for such skin type), upon failure of the light source 902 or other system component, upon indication by a user interface and control subsystem, and/or upon release of improvements/corrections in the light cartridge components made by a manufacturer thereof.
  • the cartridge 900 may contain each of these components, those skilled in the art will recognize that the cartridge 900 may contain fewer components (such as, for example, only the light source 902 , reflector 904 , and thermally conductive material 908 , or substantially any other combination of components).
