  • the light therapy device 100 includes a mask unit 10, which may be secured by the user for supporting the light therapy device 100 thereon.
  • FIGS. 1-2 show embodiments of the mask unit 10. As shown in
  • the mask unit 10 is in form of goggles.
  • the mask unit 10 includes a frame 12 adapted to surround an eye area of the user.
  • the mask unit 10 further includes a pair of retainers 14.
  • Each of the pair of retainers 14 extends from the frame 12. The user may secure the pair of retainers 14 around its ear portion for securing the frame 12, and thereby the light therapy device 100 over the eye area of the user, as shown in FIG. 8.
  • members 16a and 16b, and the pair of retainers 14 integrally the frame 12 includes elongated extending from the elongated members 16a, 16b, such that, the frame 12 is adapted to rest just above the eyes of the user.
  • FIGS. 3-4 show another embodiment of the mask unit 10.
  • the frame 12 is adapted to cover the eye area of the user rather than just surrounding the eye area, as in case of embodiments depicted in FIGS. 1- 2.
  • the frame 12 according to this embodiment includes a pair of cavities 18a and 18b capable of covering or encapsulating the eye area of the user.
  • the pair of retainers 14 integrally extends from the elongated members 18a, 18b, such that, the frame 12 is adapted to cover the eyes of the user.
  • the mask unit 10 further includes a light emitting panel 20.
  • the light emitting panel 20 is fitted on the frame 12, as shown in FIGS. 1-4.
  • the light emitting panel 20 includes a plurality of light emitting sources 22.
  • the light emitting sources 22 are capable of producing light in particular wavelength required for the light therapy which is to be provided to the user.
  • the light emitting sources 22 are light emitting diodes capable of emitting light in blue spectrum of about 470 nanometers.
  • OLED Organic Light Emitting Diodes
  • AMOLED Active-matrix Organic light-emitting diode
  • the light emitting sources 22 are capable of emitting red colored light. In other embodiments, other colored lights may be employed.
  • the light emitting panel 20 is usually positioned in a manner that illuminates retinal part of the user's eyes without obstructing normal vision and by minimising glare, so that the emitted light reaches the third photoreceptor in human's eye - the melanopsin. It will be apparent to a person skilled in the art that when the light reaches the melanopsin, the photoreceptor sends signals to the master clock in user's body, situated in the Suprachiasmatic Nucleus. These signals affect the biological clock which shifts accordingly. [0040] As shown in various embodiments shown in FIGS. 1, 3 and 4, the light emitting panel 20 is assembled on a frontal portion 24 of the frame 12. In FIG.
  • the light emitting panel 20 is assembled at a rear portion 27 of the pair of retainers 14.
  • the light is guided by means of light guiding tubes 26, which optically guides light emitted by the light emitting panel 20, as shown in FIG. 2B.
  • the light guiding tubes 26 are like a tube, which can allow the light to guide through using the principle of internal reflection.
  • the light emitting panel 20 may be configured in any manner which allows the light to illuminate the user's eyes.
  • the frame 12 further may include a nose rest 28. As shown in
  • the nose rest 28 is assembled on the frame 12.
  • the nose rest 28 is assembled at a middle portion 30 of the frame 12.
  • the nose rest 28 is adapted to support the frame 12 over a nose area of the user. This allows the user to retain the light therapy device 100 thereon.
  • the nose rest 28 includes a fail safe mechanism (not shown in figures) designed to prevent unwarranted operation of the light therapy device 100 or to cease operation of the light therapy device 100 under certain conditions.
  • a fail safe mechanism (not shown in figures) designed to prevent unwarranted operation of the light therapy device 100 or to cease operation of the light therapy device 100 under certain conditions.
  • conventional (prior art) light therapy devices do not have any means to ensure their safe operations. It will be apparent to a person skilled in the art that continuous exposure to blue light or some other colored lights, accidentally, through misuse or otherwise, may have some harmful effects on the users. Therefore, there is a need to keep a check on such accidental use or prevent such misuse.
  • the fail safe mechanism includes at least one sensor (not shown).
  • the at least one sensor is embedded in the nose rest 28.
  • the at least one sensor may also be embedded in other parts of the light therapy device 100. Accordingly, in another embodiment of the present invention the at least one sensor is embedded in the pair of retainers 14 of the light therapy device 100. In such a situation, the at least one sensor gets activated when the user secures the pair of retainers 14 over its ears.
  • the at least one sensor is calibrated to initiate operation of the light therapy device 100 based on detection of a contact of the nose rest 28 with the nose area of the user.
  • the at least one sensor is at least one capacitive sensor.
  • the nose rest 28 includes two capacitive sensors. More specifically, the capacitive senor is capable of detecting a contact of the nose rest 28 or the pair of retainers 14 with a skin of the user, and accordingly authorizing the operation of the light therapy device 100 based on detection of such contact. In this manner, the light therapy device 100 only gets operational when it has been worn by the user, thereby preventing the situations where the light therapy device 100 gets accidentally activated causing unwarranted harm or gets misused.
  • the least one sensor is calibrated to retard or cease operation of the light therapy device 100 based on various situations.
  • the at least one sensor is a temperature sensor or a thermostat calibrated to detect the operating temperature of the light therapy device 100, and ceasing operation of the light therapy device 100 in case the operating temperature is above a preset threshold of overheating. In this case, the temperature sensor will provide an additional safety feature to the light therapy device 100 and will cease overheating.
  • the light therapy device 100 includes a controller 32
  • the controller 32 is in operational communication with the light emitting panel 20 of the light therapy device 100.
  • the controller 32 is adapted to control operational characteristics of the light emitting sources 22.
  • the controller 32 is therefore responsible to vary various parameters of the operation of the light emitting panel 20 for providing the light therapy. Examples of the operational characteristics may include but are not limited to intensity of the light, variance of the intensity, duration of operation and other similar parameters.
  • the controller 32 may also be coupled with the at least one sensor embedded in the mask unit 10 for initiating or ceasing the operation of the light therapy device 100 as described above, or for other control required based on detections made by the at least one sensor.
  • the controller 32 is a printed circuit board.
  • the PCB mechanically supports and electronically connects Bluetooth and different cables (connected to the light emitting panel 20) and operations.
  • the light therapy device 100 further includes at least one light guide plate 34 (a pair of light guide plates 34 are shown in the FIGS. 1 and 2) in optical communication with the light emitting sources 22.
  • the light guide plate 34 is adapted to controllably guide the light emitted by the light emitting sources 22 into the eyes of the user. It will be apparent to a person skilled in the art that direct ingress of the light into the eye of the user is sometimes harmful. Accordingly, the light guide plate 34 is provided to controllably guide the light emitted by light emitting sources 22 into the eyes of the user.
  • the at least one light guide plate 34 is configured so that it faces the eyes of the user.
  • the light guide plate 34 may be curved, as shown in FIGS. 5A and 5B.
  • the at least one light guide plate 34 may also be straight without having a curve portion.
  • the at least one light guide plate 34 includes a chamfer 36, as shown in FIG. 5C.
  • the chamfer 36 may include a 45 degree slant at its leading edge 37. The slant of the leading edge 37 brings a prism functionality to the at least one light guide plate 34 for controllably guiding the light into the eyes of the user.
  • the chamfer 36 may include a slant which is between 1 degrees to 89 degrees which is enough to controllably guide the light emitted by the light emitting sources 22 into the eyes of the user. In another embodiment, the chamfer 36 is less than 45 degrees for controllably guiding the light emitted by the light emitting sources 22 into the eyes of the user.
  • FIG. 5C The optical operation of the at least one light guide plate 34 is shown in FIG. 5C.
  • the light emitted by the light emitting panel 20, and more particularly, by the light emitting sources 22, is guided to the pupil of the eye by diffraction from the leading edge 37 of the chamfer 36.
  • the at least one guide plate 34 is a single plate which has a shape of vision glass. As shown in said FIG. 6, in such configuration, the need of 45 degree chamfer, such as chamfer 36, is precluded.
  • a flat surface 38 (a) which has the light emitting sources 22 in optical communication therewith.
  • a surface 38 (b) which is made rough using sand blasting, or other similar techniques.
  • the surface 38 (b) includes a special pant coating, such as white paint to reflect the light emitted towards the eyes.
  • the white paint may be continuous or in form of dots.
  • This roughness or white spots ensure that the surface 38 (b) becomes a point source of light itself when the light falls on it.
  • the light that does not touch the surface passes as normal. Accordingly, only some part of light is guided towards the user's eye.
  • the FIG. 6 also demonstrates the optical mechanism which guides the light using the light guiding plate 34.
  • such vision glass allows the at least one light guide plate 34 to act as a normal vision glass if the light emitting panel 20 is non-operational. In such a situation, the at least one light guide plate 34 will act as a normal vision glass since the rough surface is not obstructing the vision of the user. Further, the rough surface 38 is at a position such that it does not obstruct the normal vision of the user. This allows the user to use the light therapy device 100 as a normal conventional spectacle by turning the light therapy device 100 un-operational.
  • the at least one light guide plate 34 is composed of solid transparent poly carbonate material (plastic). In another embodiment, the at least one light guide plate 34 may be composed of transparent material like glass.
