In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some, rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
As shown in
The infrared emission module (6) includes a rubber-iron element (61). The rubber-iron element (61) includes an assembly groove. The assembly groove is provided therein with a reflective film (62), a light guide plate (63), a diffusive film (64), a lower brightness enhancement film (65), an upper brightness enhancement film (66), and a black-black double-sided tape (68) in order from bottom to top. The black-black double-sided tape (68) is bonded to an inner side of the first cover (2) or the second cover (3). An infrared light-emitting diode (LED) point light source (67) is located at one side of the light guide plate (63) and between the reflective film and the diffusive film (64). The infrared LED point light source (67) is configured to emit 600-750 nm infrared light.
The device body (1) is provided therein with a controller (not shown in the figure). The controller is electrically connected with the infrared LED point light source (67).
It should be noted that the assembly groove of the rubber-iron element (61) is configured to provide an assembly space for each component and plays a protective role. Preferably, the rubber-iron element (61) is integrally injection-molded. The reflective film is configured to reflect infrared light scattered from a back side of the light guide plate (63) back to the light guide plate (63), so as to increase the light brightness and uniformity. The light guide plate (63) is configured to convert the point light emitted by the infrared LED point light source (67) into an area light source, and perform transmission and heat dissipation of the light to improve the uniformity of light transmission and scattering by the light guide plate (63). Preferably, in this embodiment, the light guide plate is made of polymethyl methacrylate (PMMA, also known as acrylic or organic glass) by laser engraving, and the laser-engraved light guide plate (63) has a V-CUT pattern. The light guide plate (63) has a uniformity of no less than 90%, while the existing light guide plate (63) has a uniformity of generally not less than 80%. There are differences in the flatness and uniformity of a dot matrix pattern printed on the existing light guide plate (63) using a traditional dot printing method, and the light transmission uniformity of the existing light guide plate can only achieve ≥80%. Therefore, the light guide plate (63) in this embodiment is superior to the traditional light guide plate (63), and is effectively suitable for stimulating and training biological cells in the retina of the human eye.
It should be noted that the diffusive film (64) is configured to further improve the uniformity of the area light source through a surface diffusion particle. The lower brightness enhancement film (65) and the upper brightness enhancement film (66) are respectively configured to focus and re-diffuse the infrared light source through a surface micro-pattern, so as to further improve the brightness and uniformity of the module. The infrared LED point light source (67) has an emission angle of no less than 120°. The lower brightness enhancement film (65) and the upper brightness enhancement film (66) each are provided with a prism. The prism has an adjustable installation angle to generate focused light perpendicular to a direction of the human eye, so as to avoid overflow of the infrared light, and ultimately form infrared light perpendicular to the human eye at 90°. The design can achieve the goal of more concentrated and direct stimulation and activation of cone and rod cells in the retina of the human eye, which is beneficial for vision health. In contrast, a traditional white LED has an emission angle of not greater than 100°, such that the light emitted is scattered and cannot be focused. Therefore, this embodiment can be better used for stimulation and training of biological cells in the retina of the human eye.
Based on the disclosed content above, the first cavity (4) and the second cavity (5) are sequentially arranged on the side of each of the first cover (2) and the second cover (3) of the device body (1) facing the human eye. The first cavity (4) is provided therein with the infrared emission module (6), and the second cavity (5) is provided therein with the dark training room in close contact with the human eye. The infrared LED point light source (67) of the infrared emission module (6) is configured to emit 600-750 nm infrared light to stimulate the cone and rod cells in the retina of the human eye, causing the eye to secrete more dopamine. In this way, the blood vessel in the choroid of the human eye is dilated to strengthen the blood circulation in the retina and choroid, and move the thickening position of the wall of the blood vessel forward, thereby shortening the eye axis and improving uncorrected visual acuity (UCVA). The human eye observes the different colored light environments created by the photo-biological training room for a long time to relax ciliary muscles and restore their elasticity. The design improves the curvature adjustment ability of the eye lens, ensuring normal refractive adjustment of the eye.
In a possible design, the device body (1) is further provided therein with a music playback module (not shown in the figure). The music playback module is electrically connected with the controller. The music playback module is configured to play music, such as brainwave light music, to stimulate the brain's nervous system. The design can completely relax the brain nerves so as to relax the eye muscles of the vision system, further improving vision health.
In a possible design, the infrared LED point light source (67) includes a substrate layer. The substrate layer is provided thereon with a Bragg optical reflection layer.

The N-AlGaInP confinement layer is provided thereon with an I-AlGaInP active layer with a thickness of 0.1-0.3 μm. The I-AlGaInP active layer is provided thereon with a P-AlGaInP confinement layer with a thickness of 34,000-36,000 nm. The P-AlGaInP confinement layer is provided thereon with a p-type gallium phosphide (P-GaP) window layer with a thickness of 47,000-49,000 nm. The substrate layer includes a gallium arsenide (GaAs) substrate with a thickness of 220-320 nm. A surface of the GaAs substrate is provided with a silicon dioxide (SiO2) protective layer with a thickness of 200-220 nm. A surface of the SiO2 protective layer is provided with an indium tin oxide (ITO) enhancement layer with a thickness of 200-250 nm. The infrared LED point light source (67) formed by connecting these layers can emit 600-750 nm infrared light.
In a possible design, in order to control the start and stop of the infrared LED point light source, the controller includes a light emission control circuit. The light emission control circuit includes an SY7201ABC microprocessor chip U4. A pin LX of the microprocessor chip U4 is connected with one terminal of an inductor L1 and a positive terminal of the infrared LED point light source. A negative terminal of the infrared LED point light source is connected with a first capacitor C3 and then grounded. A ground pin GND of the microprocessor chip U4 is grounded. A pin FB of the microprocessor chip U4 is connected with one terminal of a first resistor R13, one terminal of a second resistor R12, and a positive pole of a power supply. The other terminal of the first resistor R13 and the other terminal of the second resistor are grounded. A pin IN of the microprocessor chip U4 is connected with the other terminal of the inductor L1, one terminal of a second capacitor C2, and a 3.3 V voltage. The other terminal of the second capacitor C2 is grounded. A pin OVP of the microprocessor chip U4 is connected in series with a third resistor R9 and then connected with one terminal of the first capacitor C3 and a negative pole of the power supply. Pins EN/PWM of the microprocessor chip U4 are connected in series with fourth resistor R10 and then connected with a power supply voltage VCC.
Preferably, in this embodiment, the parameters of each circuit component of the light emission control circuit are as follows: inductance of the inductor L1: 6.8 μH (microhenry); capacitance of the first capacitor C3: 1 μ/50 V; resistance of the first resistor R13 and the second resistor R12: 10 ohms; capacitance of the second capacitor C2: 4.7μ; resistance of the third resistor R9 and the fourth resistor R10: zero. An output constant current of the light emission control circuit is OUT=200 mV, and the inductance of the inductor L1 is not greater than 6.8 μH, otherwise a power supply integrated circuit (IC) may experience severe heating.
