PHOTOBIOMODULATION THERAPY SYSTEMS AND DEVICES

BACKGROUND
Field

Various embodiments disclosed herein relate to photobiomodulation therapy devices. Certain embodiments relate to light therapy devices configured to emit at least one of red and infrared light.

Description of Related Art

Photobiomodulation therapy (or light therapy) is a therapeutic technique that uses low-level wavelengths of light to improve health and treat a variety of health conditions, including skin issues, such as wrinkles, scars, and persistent wounds, among many other conditions. Photobiomodulation therapy uses non-ionizing light sources, including lasers, light emitting diodes, and/or broadband light, in the visible (400-700 nm) and infrared (700-1100 nm) electromagnetic spectrum. Photobiomodulation is a nonthermal process involving endogenous chromophores eliciting photophysical (i.e. linear and nonlinear) and photochemical events at various biological scales. Similar to how plants use sunlight to heal and grow, humans and animals are able to harness these wavelengths of light and turn them into cellular energy. This treatment stimulates the body's natural healing processes.

Currently, there are a number of photobiomodulation therapy devices available on the market. However, many of these devices are too small and require multiple sessions to treat large areas. As a result, there is a need for a photobiomodulation therapy system that can treat several areas in fewer treatments.

The at least one reflector 30 may be configured to surround at least a portion of the at least one LED 20 to thereby reflect the light emitted from the at least one LED 20. In some embodiments, the front bezel 14 comprises both the at least one lens 28 and the at least one reflector 30. As such, the front bezel 14 may be considered a “dual-purpose” element of the system 10. (And when the function as a heat sink 24 is included, the front bezel 14 may be considered a “tri-purpose” element.) In some embodiments, an interior portion 26 (shown in FIG. 2) of the front bezel 14 is coated with a white surface finish to thereby reflect light.

The at least one reflector 30 may comprise the portion of the front bezel 14 surrounding each LED of the at least one LED 20 and each lens of the at least one lens 28. For example, going back to FIG. 2, each reflector of the at least one reflector 30 may comprise one of the circular cavities of the front bezel 14. In some embodiments, each cavity is positioned around one LED of the at least one LED 20. Each cavity may be at least partially covered, for example on a front surface of the front bezel 14, with a lens of the at least one lens 28. An interior portion 26 of each reflector of the front bezel 14 may be coated with a white surface finish to thereby reflect light. In some embodiments, the interior portion 26 comprises another reflective surface coating, such as chrome. The at least one reflector 30 may be configured to concentrate the light emitted from the at least one LED 20 and direct the concentrated light toward the at least one lens 28.

FIGS. 4A and 4B show front and back views, respectively, of the PCBA 18. In many embodiments, the PCBA 18 is coupled to the housing 12 and located in an interior portion of the housing 12 between the front bezel 14 and the back portion 16.

The infrared light may be pulsed for a certain amount of time; for example, the infrared light may be emitted for two seconds every five seconds. The infrared light may be pulsed for a shorter or longer duration than two seconds. In some embodiments, the Recovery Plus Mode comprises pulsing red light and substantially continuous infrared light. The Recovery Plus Mode may include pulsed or continuous emission of infrared and/or near infrared light. The duration of a treatment session using Recovery Plus Mode may be selected by a user of the device 10 via at least one of the mobile application and the at least one user control. The Recovery Plus Mode may help facilitate cellular recovery by encouraging the removal of waste products from cells during a “quench period” in the cellular recovery process. The device 10 may be configured to automatically shut off at the end of a Recovery Plus Mode session. A user may manually shut off the device 10.

When the device 10 is arranged and configured to operate in the Ambient Mode, the at least one LED 20 may be configured to emit ambient light. In many embodiments, the at least one LED 20 is configured to emit substantially continuous red light in the Ambient Mode. The Ambient Mode may be configured to operate for any duration selected by a user; for example, ten minutes, twenty minutes, thirty minutes, sixty minutes, etc. The device 10 may be configured to automatically shut off after the preselected duration for Ambient Mode. A user may manually shut off the device 10. In many embodiments, the Ambient Mode is configured such that the at least one LED 20 emits substantially continuous red light at 50% of maximum brightness. The user may select a desired brightness level for Ambient Mode. Though used for “ambient” light purposes, during the Ambient Mode, the user may experience any of the various benefits provided by exposure to red light.

When the device 10 is arranged and configured to operate in the Alarm Clock Mode, the at least one LED 20 may be configured to emit ambient light upon at least one of a predetermined condition and at a predetermined time. It should be noted that the ambient light emitted in the Alarm Clock Mode may comprise the same light emitted in the Ambient Mode—substantially continuous red light emitted at 50% brightness. The ambient light emitted in the Alarm Clock Mode may include a ramp-up sequence before reaching a predetermined brightness level (e.g., 50%), wherein the at least one LED 20 is configured to emit light of increasing intensity over a predetermined period of time. For example, the at least one LED 20 may be configured such that, upon (or before) the predetermined condition and/or at (or before) the predetermined time, the at least one LED 20 is configured to turn on and emit red light at 10% brightness with a gradual increase to 50%. The user may select the beginning brightness and the duration of the ramp-up sequence, as well as the peak brightness level.

For example, the user may program the Alarm Clock Mode such that the device 10 is configured to emit red light at 50% brightness at 6:30 AM every morning, Monday-Friday. Beginning at 6:20 AM on Monday-Friday, the at least one LED 20 may be configured to emit red light at 10% brightness. The at least one LED 20 may be configured to gradually increase the brightness such that at 6:25 AM, the at least one LED 20 emits red light at 25% brightness. The at least one LED 20 may continue gradually increasing the brightness over the next five minutes such that at 6:30 AM, the red light is emitted at 50% brightness. A user may forgo the ramp-up sequence and instead configure the device 10 to turn on and immediately emit red light at the predetermined brightness at the predetermined time.

In some embodiments, the Alarm Clock Mode is configured such that the at least one LED 20 emits ambient light upon a predetermined condition. The predetermined condition may comprise a variety of conditions. For example, a remote computing device of the user may be communicatively coupled to the device 10 such that a mobile application on the remote computing device is configured to trigger the at least one LED 20. In some embodiments, the mobile application comprises a sleep tracking application configured to trigger the at least one LED 20 after a predetermined amount of sleep. The sleep tracking application may be configured to trigger the at least one LED 20 upon detection that the user is in a “light” phase of sleep, which may make it easier and more pleasant for the user to wake up.

As another example, the mobile application may be communicatively coupled to a smart device of the user's home, such as a coffee maker. In some embodiments, the mobile application is configured to trigger the at least one LED 20 upon completion of brewing at least one of a pot and a cup of coffee. The mobile application may be configured to trigger the at least one LED 20 upon starting to brew at least one of a pot and a cup of coffee. The mobile application may be coupled to another smart device, such as a smart thermostat. In some embodiments, the mobile application is configured to trigger the at least one LED 20 when the smart thermostat reaches a predetermined temperature.

“Triggering” the at least one LED 20 may comprise starting a ramp-up sequence. In some embodiments, “triggering” the at least one LED 20 comprises immediately emitting ambient light at the predetermined brightness (e.g., 50%). The Alarm Clock Mode may be configured to automatically shut off the at least one LED 20 after a predetermined amount of time. For example, the at least one LED 20 may be configured to shut off thirty minutes after at least one of the predetermined time and the occurrence of the predetermined condition. The user may manually turn off the device 10.

As previously mentioned, the at least one LED 20 may comprise a dimmable LED. A dimming feature may be included in any or all of the Recovery Plus Mode, the Ambient Mode, and the Alarm Clock Mode. The dimming feature may also be integrated into a light therapy session using the device 10. In some embodiments, regardless of the Mode, the at least one LED 20 may ramp-up from off to full (or a predetermined) brightness in a ten second period. When the device 10 is turned off and/or at the end of a treatment session, the at least one LED 20 may ramp-down from the existing brightness level to off in a ten second period. The ramp-up and/or ramp-down period may comprise more or fewer than ten seconds.

In some embodiments, at least one of the Recovery Plus Mode, the Ambient Mode, and the Alarm Clock Mode includes a beeper function. The device 10 may be configured to emit a sound (e.g., “beep”) as an indication of progress of a session using at least one of the stated Modes. For example, during the Recovery Plus Mode, the device 10 may be configured to beep at the beginning of a session, when two minutes remain in the session, and at the conclusion of the session. The device 10 may be configured to emit a sound as an indication of progress in a “regular” session that does not use one of the stated modes. Beeper functionality, including the volume of the sound emitted, the type of sound emitted (e.g., beep, chirp, chime, or the like), the number of times the sound is emitted (e.g., single beep vs. double beep), and when the sound is emitted (e.g., start of a session, halfway through a session, five minutes remaining, one minute remaining, end of session, every two minutes during a session, etc.) may be customizable based on preferences of the user. Beeper functionality may be programed via the device 10, using the at least one user control, or via a mobile application on the remote computing device. A user may choose to forgo the beeper function so that the device 10 does not emit any sound during operation.

As shown in FIG. 14, the at least one LED 108 may be configured to emit infrared light at one predetermined duty cycle 114 and red light at another, different, predetermined duty cycle 114. For example, in a given session time, the at least one LED 108 may be configured to ramp-up emission of infrared light to a 50% frequency for a period of time, increase to a 75% frequency for a period of time, decrease back to 50% for a period of time, increase back to 75% for a period of time, decrease back to 50% for a final time, then ramp-down to zero emission at the end of the session. The amount of time infrared light is emitted at each predetermined frequency 112 may be substantially the same throughout the duration of the session. The amount of time may vary during the course of the session.

For red light therapy, the at least one LED 108 may be configured to ramp-up to 25% frequency for a period of time, increase to 50% frequency for a period of time, decrease back to 25% for a period of time, increase back to 50% for a period of time, decrease back to 25% for a final time, then ramp-down to zero emission at the end of the session. As with the infrared emission, the amount of time red light is emitted at each predetermined frequency 112 may be substantially the same throughout the duration of the session. The amount of time may vary during the course of the session.

The predetermined duty cycle 114 may comprise at least one predetermined frequency 112 not shown in FIG. 14. In some embodiments, red light is configured to be emitted at a higher frequency than infrared light. Red and infrared light may be emitted at the same frequency.

In some embodiments, the predetermined duty cycle 114 comprises steady emission (e.g., constant emission at a single predetermined frequency 112) of, for example, red light, and emission of infrared light at varying frequencies. The predetermined duty cycle 114 may comprise steady emission of infrared light and emission of red light at varying frequencies. In some embodiments, the predetermined duty cycle 114 comprises emission of only red light or infrared light. Varying the predetermined frequency 112 for a predetermined duty cycle 114 may include more than two different frequencies. For example, the predetermined duty cycle 114 may include emission of red light at 10%, then 70%, then 35%, then 95%, then 100%, then 25%, then 20%, then 60%, then zero. Any combination of frequency emissions may be implemented in the predetermined duty cycle 114.

When the device 102 is arranged and configured to operate in the Recovery Plus Mode, the at least one LED 108 may be configured to emit pulsed infrared light. In many embodiments, the at least one LED 108 is configured to emit substantially continuous red light in the Recovery Plus Mode. The pulsed infrared light may be emitted at a single frequency. In some embodiments, the infrared light is pulsed at varying frequencies throughout the duration of the Recovery Plus Mode. “Varying” frequencies may comprise frequencies between 0 and 100 Hz, emitted at different duty cycle percentages. For example, the Recovery Plus Mode may include pulsing infrared light at 25 Hz and at 50% brightness for two minutes, increasing the frequency to 50 Hz at 75% brightness for two minutes, then reducing the frequency to 35 Hz and 40% brightness for two minutes. The Recovery Plus Mode may comprise any combination of frequency and brightness per duty cycle. The infrared light may be pulsed for a certain amount of time; for example, the infrared light may be emitted for two seconds every five seconds. The infrared light may be pulsed for a shorter or longer duration than two seconds. In some embodiments, the Recovery Plus Mode comprises pulsing red light and substantially continuous infrared light. The Recovery Plus Mode may include pulsed or continuous emission of infrared and/or near infrared light. The duration of a treatment session using Recovery Plus Mode may be selected by a user of the device 102 via at least one of the mobile application and the at least one user control. The Recovery Plus Mode may help facilitate cellular recovery by encouraging the removal of waste products from cells during a “quench period” in the cellular recovery process. The device 102 may be configured to automatically shut off at the end of a Recovery Plus Mode session. A user may manually shut off the device 102.

When the device 102 is arranged and configured to operate in the Ambient Mode, the at least one LED 108 may be configured to emit ambient light. In many embodiments, the at least one LED 108 is configured to emit substantially continuous red light in the Ambient Mode. The Ambient Mode may be configured to operate for any duration selected by a user; for example, ten minutes, twenty minutes, thirty minutes, sixty minutes, etc. The device 102 may be configured to automatically shut off following the end of the preselected duration of the Ambient Mode session. A user may manually shut off the device 102. In many embodiments, the Ambient Mode is configured such that the at least one LED 108 emits substantially continuous red light at 50% of maximum brightness. The user may select a desired brightness level for Ambient Mode. Though used for “ambient” light purposes, during the Ambient Mode, the user may experience any of the various benefits provided by exposure to red light.

When the device 102 is arranged and configured to operate in the Alarm Clock Mode, the at least one LED 108 may be configured to emit ambient light upon at least one of a predetermined condition and at a predetermined time. It should be noted that the ambient light emitted in the Alarm Clock Mode may comprise the same light emitted in the Ambient Mode—substantially continuous red light emitted at 50% brightness. The ambient light emitted in the Alarm Clock Mode may include a ramp-up sequence before reaching a predetermined brightness level (e.g., 50%), wherein the at least one LED 108 is configured to emit light of increasing intensity over a predetermined period of time. For example, the at least one LED 108 may be configured such that, upon (or before) the predetermined condition and/or at (or before) the predetermined time, the at least one LED 108 is configured to turn on and emit red light at 10% brightness with a gradual increase to 50%. The user may select the beginning brightness and the duration of the ramp-up sequence, as well as the peak brightness level.

For example, the user may program the Alarm Clock Mode such that the device 102 is configured to emit red light at 50% brightness at 6:30 AM every morning, Monday-Friday. Beginning at 6:20 AM on Monday-Friday, the at least one LED 108 may be configured to emit red light at 10% brightness. The at least one LED 108 may be configured to gradually increase the brightness such that at 6:25 AM, the at least one LED 108 emits red light at 25% brightness. The at least one LED 108 may continue gradually increasing the brightness over the next five minutes such that at 6:30 AM, the red light is emitted at 50% brightness. A user may forgo the ramp-up sequence and instead configure the device 102 to turn on and immediately emit red light at the predetermined brightness at the predetermined time.

In some embodiments, the Alarm Clock Mode is configured such that the at least one LED 108 emits ambient light upon a predetermined condition. The predetermined condition may comprise a variety of conditions. For example, a remote computing device 136 of the user may be communicatively coupled to the device 102 such that a mobile application on the remote computing device 136 is configured to trigger the at least one LED 108. In some embodiments, the mobile application comprises a sleep tracking application configured to trigger the at least one LED 108 after a predetermined amount of sleep. The sleep tracking application may be configured to trigger the at least one LED 108 upon detection that the user is in a “light” phase of sleep, which may make it easier and more pleasant for the user to wake up.

As another example, the mobile application may be communicatively coupled to a smart device of the user's home, such as a coffee maker. In some embodiments, the mobile application is configured to trigger the at least one LED 108 upon completion of brewing at least one of a pot and a cup of coffee. The mobile application may be configured to trigger the at least one LED 108 upon starting to brew at least one of a pot and a cup of coffee. The mobile application may be coupled to another smart device, such as a smart thermostat. In some embodiments, the mobile application is configured to trigger the at least one LED 108 when the smart thermostat reaches a predetermined temperature.

“Triggering” the at least one LED 108 may comprise starting a ramp-up sequence. In some embodiments, “triggering” the at least one LED 108 comprises immediately emitting ambient light at the predetermined brightness (e.g., 50%). The Alarm Clock Mode may be configured to automatically shut off the at least one LED 108 after a predetermined amount of time. For example, the at least one LED 108 may be configured to shut off thirty minutes after at least one of the predetermined time and the occurrence of the predetermined condition. The user may manually turn off the device 102.

As previously mentioned, the at least one LED 108 may comprise a dimmable LED. A dimming feature may be included in any or all of the Recovery Plus Mode, the Ambient Mode, and the Alarm Clock Mode. The dimming feature may also be integrated into a light therapy session using the device 102. In some embodiments, regardless of the Mode, the at least one LED 108 may ramp-up from off to full (or a predetermined) brightness in a ten second period. When the device 102 is turned off and/or when a treatment session is finished, the at least one LED 108 may ramp-down from the existing brightness level to off in a ten second period. The ramp-up and/or ramp-down period may comprise more or fewer than ten seconds.

In some embodiments, at least one of the Recovery Plus Mode, the Ambient Mode, and the Alarm Clock Mode includes a beeper function. The device 102 may be configured to emit a sound (e.g., “beep”) as an indication of progress of a session using at least one of the stated Modes. For example, during the Recovery Plus Mode, the device 102 may be configured to beep at the beginning of a session, when two minutes remain in the session, and at the conclusion of the session. The device 102 may be configured to emit a sound as an indication of progress in a “regular” session that does not use one of the stated modes. Beeper functionality, including the volume of the sound emitted, the type of sound emitted (e.g., beep, chirp, chime, or the like), the number of times the sound is emitted (e.g., single beep vs. double beep), and when the sound is emitted (e.g., start of a session, halfway through a session, five minutes remaining, one minute remaining, end of session, every two minutes during a session, etc.) may be customizable based on preferences of the user. Beeper functionality may be programed via the device 102, using the at least one user control, or via a mobile application on the remote computing device. A user may choose to forgo the beeper function so that the device 102 does not emit any sound during operation.

For example, a section titled “Topic 1” may include embodiments that do not pertain to Topic 1 and embodiments described in other sections may apply to and be combined with embodiments described within the “Topic 1” section.

The various features and processes described above may be used independently of one another, or may be combined in various ways. All possible combinations and subcombinations are intended to fall within the scope of this disclosure. In addition, certain methods, events, states, or process blocks may be omitted in some implementations. The methods, steps, and processes described herein are also not limited to any particular sequence, and the blocks, steps, or states relating thereto can be performed in other sequences that are appropriate. For example, described tasks or events may be performed in an order other than the order specifically disclosed. Multiple steps may be combined in a single block or state. The example tasks or events may be performed in serial, in parallel, or in some other manner. Tasks or events may be added to or removed from the disclosed example embodiments. The example systems and components described herein may be configured differently than described. For example, elements may be added to, removed from, or rearranged compared to the disclosed example embodiments.

Conditional language used herein, such as, among others, “can,” “could,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without author input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular embodiment. The terms “comprising,” “including,” “having,” and the like are synonymous and are used inclusively, in an open-ended fashion, and do not exclude additional elements, features, acts, operations and so forth. Also, the term “or” is used in its inclusive sense (and not in its exclusive sense) so that when used, for example, to connect a list of elements, the term “or” means one, some, or all of the elements in the list. Conjunctive language such as the phrase “at least one of X, Y, and Z,” unless specifically stated otherwise, is otherwise understood with the context as used in general to convey that an item, term, etc. may be either X, Y, or Z. Thus, such conjunctive language is not generally intended to imply that certain embodiments require at least one of X, at least one of Y, and at least one of Z to each be present.

The term “and/or” means that “and” applies to some embodiments and “or” applies to some embodiments. Thus, A, B, and/or C can be replaced with A, B, and C written in one sentence and A, B, or C written in another sentence. A, B, and/or C means that some embodiments can include A and B, some embodiments can include A and C, some embodiments can include B and C, some embodiments can only include A, some embodiments can include only B, some embodiments can include only C, and some embodiments can include A, B, and C. The term “and/or” is used to avoid unnecessary redundancy.

The term “substantially” is used to mean “completely” or “nearly completely”. For example, the disclosure includes, “In some embodiments, the front bezel 14 comprises substantially the entire front portion of the device 10.” In this context, “substantially the entire front portion” means that the front bezel may comprise completely or nearly completely the front portion of the device. The front bezel may comprise at least 80% of the front portion of the device, and fall within the understood meaning of “substantially” as used in this disclosure.

The term “about” is used to mean “approximately”. For example, the disclosure includes, “the power supply unit configured to output about 48 volts of power.” In this context, “about 48 volts” means “approximately” 48 volts. A power output between 45 volts and 51 volts may fall within an acceptable range of “about 48 volts”.

While certain example embodiments have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the inventions disclosed herein. Thus, nothing in the foregoing description is intended to imply that any particular feature, characteristic, step, module, or block is necessary or indispensable. Indeed, the novel methods and systems described herein may be embodied in a variety of other forms; furthermore, various omissions, substitutions, and changes in the form of the methods and systems described herein may be made without departing from the spirit of the inventions disclosed herein.
