[0002] With the change of modern lifestyle, the incidence of myopia (also called nearsightedness or shortsightedness) has increased year by year, especially among children and adolescents, becoming a global public health problem.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0037] Example
[0038] Currently, most of the light-feeding devices include a lens barrel assembly. By setting a red light generating assembly and adjusting the distance between the red light laser emitter and the filter, the intensity of the red light entering the lens barrel assembly can be adjusted to meet the needs of myopic patients with different degrees of myopia. However, under normal conditions, light in the wavelength range of 600nm to 1100nm in sunlight is most effective in treating myopia in the human eye. Although a single infrared light can be effective in treating myopia in the human eye, its effect is not as good as that of sunlight. Moreover, when infrared light is used to irradiate the human eye at close range, the heat generated will cause irreversible damage to the human eye.
[0039] Therefore, please refer to Figure 1 and Figure 5 As shown, the purpose of this embodiment is to provide a solar spectrum myopia light-feeding instrument, which includes a light source component 1, and the light source output end of the light source component 1 is sequentially installed with a filter component 2, an optical coupler component 3, an energy fiber component 4, and a homogenizing and shaping component 5, wherein the light source emitted from the emission end of the light source component 1 is filtered out by the filter component 2 to remove invalid band radiation light, and at the same time absorbs the heat generated by the thermal radiation of the light source component 1 and the heat generated by the conversion of mid-infrared and far-infrared band light, thereby ensuring the safety of the treatment process and avoiding potential damage to the eyes caused by excessive light. After that, the effective band radiation enters the optical coupler component 3 for coupling, and then enters the optical coupler component 3 for coupling, and then is input into the homogenizing and shaping component 5 through the energy fiber optic component 4 for beam expansion and shaping and energy homogenization, and finally the required output light spot 512 is obtained, thereby realizing the conversion of the light source emitted from the emission end of the light source component 1 into sunlight-like light, thereby treating myopia.
[0040] Since the light source emitted by the light source assembly 1 is required to be similar to the solar spectrum and to be able to provide the light source continuously and stably, the light source assembly 1 includes a focusing concave mirror 11, a solar-like continuous spectrum light source 12 and a focusing lens 13, and the focusing concave mirror 11 is semi-elliptical, and the focusing concave mirror 11 and the focusing lens 13 enclose a closed space, and the solar-like continuous spectrum light source 12 is installed in the closed space. The radiation spectrum of the solar-like continuous spectrum light source 12 is similar to the solar spectrum, and the radiation power is greater than 100 watts. After the radiation light emitted by the solar-like continuous spectrum light source 12 is converged by the focusing concave mirror 11 and shaped by the focusing lens 13, an approximately parallel light beam with a divergence angle ≤5° is obtained, and it is emitted from the focusing lens 13, and the spectrum of the emitted light covers ultraviolet light, visible light and infrared light;
[0041] See also Figure 2 As shown, since a nearly parallel light beam is emitted from the focusing lens 13, the light beam is accompanied by heat transfer while being output, therefore, the filter assembly 2 includes a liquid filter device 22, the liquid filter device 22 includes a filter cavity 29, the filter cavity 29 is provided with a liquid path channel 25, a detection module 26 is installed in the filter cavity 29, and an external circulating liquid control module 62 is connected to the liquid path channel 25 and realizes the exchange of the filter liquid in the filter cavity 29, the filter liquid filters out the excess heat in the input light beam, the temperature and conductivity of the filter liquid are measured with high precision by the detection module 26, and fed back to the circulating liquid control module 62, so as to realize the control of the temperature and flow rate of the filter liquid;
[0042] At the same time, since the spectrum composition of the approximately parallel light beam emitted from the focusing lens 13 includes specific wavelength components that are potentially harmful to the human eye, the light source receiving end of the liquid filter device 22 is sequentially installed with a narrowband laser filter 21, a gasket 28 and a pressing plate 27; the light source output end of the liquid filter device 22 is sequentially installed with a narrowband laser filter 23, a gasket 210 and a special-shaped flange 211; wherein, when the approximately parallel light beam emitted from the focusing lens 13 enters the liquid filter device 22, the narrowband laser filter 21 and the narrowband laser filter 23 are used in combination to jointly filter out visible light and ultraviolet light with a wavelength range of less than or equal to 600nm in the light beam; the filter liquid in the liquid filter device 22 filters out infrared light with a wavelength range greater than 1100nm, thereby obtaining effective light in the wavelength range of 600nm to 1100nm;
[0043] Since the radiation intensity of the light beam filtered by the narrow-band laser filter 1 21, the liquid filter device 22 and the narrow-band laser filter 2 23 is still uncontrollable, and the radiation intensity of the light beam is too high to cause the risk of vision loss, cataracts and eye cancer, therefore, a transmission rack 212 is installed on the side of the special-shaped flange 211 away from the gasket 2 210, and the transmission rack 212 is engaged with a continuous gradient optical filter 24; by driving the external motor, the transmission rack 212 controls the continuous gradient optical filter 24 to move continuously along the sagittal plane of the light path, so as to adjust the radiation intensity of the approximately parallel light beam emitted from the focusing lens 13, and control its spectral radiation intensity to be the same as the radiation intensity range of the solar spectrum, within the range of 25000Lx to 30000Lx, and the 8-hour RMS value (root mean square value, a statistic to measure data fluctuation or stability) of the radiation light stability does not exceed 5%, and the 8-hour PV value (peak-to-valley value, describing the difference between the maximum and minimum values of data over a period of time) of the energy fluctuation does not exceed 8%.
[0044] See also Figure 3 As shown, if there is chromatic aberration in the optical coupler component 3, light of different wavelengths will be focused on different positions when passing through the optical coupler component 3, resulting in the inability to accurately focus the therapeutic light on the retina, thereby affecting the therapeutic effect. Therefore, the optical coupler component 3 adopts an achromatic design to achieve the coupling of red light and near-infrared light in the wavelength range of 600nm to 1100nm. The optical coupler component 3 includes an optical coupler housing 36, and the light source receiving end of the optical coupler housing 36 is coaxially mounted with optical lens three 33, optical lens two 32 and optical lens one 31 in sequence. The optical lens one 31 is optical lens one 31, and the light source receiving end of the optical lens one 31 is mounted with an optical pressure ring 34, and the optical pressure ring 34 is connected to the optical coupler housing 36. The optical lens 3 31 is fixed by threading and the optical lens 3 32 is fixed by threading. A fixed optical path flange 1 35 is installed between the optical lens 3 33 and the optical lens 2 32, and the fixed optical path flange 1 35 is movably connected to the optical coupler housing 36, so as to adjust the optical path of the optical lens 3 33 and the optical lens 2 32. The light source output end of the optical coupler assembly 3 is movably connected to a fiber input flange 37, and the fiber input flange 37 is coaxial with the optical lens 3 33. The light beam emitted from the filter assembly 2 passes through the optical lens 1 31, the optical lens 2 32 and the optical lens 3 33 in sequence, and the light beam is converged to the fiber end face of the fiber input flange 37. The fiber input flange 37 can be moved back and forth along the central optical axis of the optical coupler housing 36 to ensure that the radiated light is efficiently coupled into the energy fiber assembly 4.
[0045] Since the selection of the energy optical fiber component 4 needs to consider power transmission capability, damage resistance, stability, speed and optical path distribution, the energy optical fiber component 4 is a large-core energy optical fiber, which can be a large-core single-core optical fiber, a multi-core optical fiber bundle or a Y-type optical fiber; to facilitate the installation of the energy optical fiber component 4, the light source receiving end of the homogenizing and shaping component 5 is fixed with a fiber output flange 57, and the two ends of the energy optical fiber component 4 are respectively fixedly connected to the fiber input flange 37 and the fiber output flange 57.
[0046] See also Figure 4 As shown, after the light beam is transmitted through the energy fiber component 4, the internal energy of the light beam is not evenly distributed, and the size of the light beam is not consistent with the size of the retina. Therefore, the homogenization and shaping component 5 includes a homogenization and shaping device 510. After the light beam output by the energy fiber component 4 passes through the optical lens 4 51, the optical lens 52 and the optical homogenization lens 53 in sequence, the light beam expansion and shaping and energy homogenization are realized.
[0047] Specifically, the light source receiving end of the homogenizer 510 is sequentially installed with a fixed optical path flange 2 59 and an adjustable optical path flange 58, and the fixed optical path flange 2 59 and the adjustable optical path flange 58 are movably connected; the optical fiber output flange 57 and the adjustable optical path flange 58 are coaxially movably connected, and the optical lens 4 51 is installed on the optical fiber output flange 57, and the focal plane of the optical lens 4 51 coincides with the position of the optical fiber end face in the optical fiber output flange 57; the light source output end of the fixed optical path flange 2 59 is fixed with an optical lens 5 52, and the optical path flange 58 is adjusted by rotating the adjustable optical path flange 58. Flange 58 adjusts the distance between fixed optical path flange 2 59 and optical fiber output flange 57, thereby adjusting the optical path between optical lens 4 51 and optical lens 5 52 to achieve beam expansion and shaping; the light source output end of the homogenizer 510 is fixed with an optical homogenizer 53 and a homogenizer fixed pressure ring 511 in sequence, and the position of the optical homogenizer 53 is fixed to achieve energy homogenization of the output light beam. The output light spot 512 is square in shape, and the size of the output light spot 512 is adjustable. The energy distribution uniformity of the output light spot 512 is greater than 90%. Considering the detection of the energy of the output light spot 512, the detector 54 is fixed on the outside of the homogenizer fixed pressure ring 511;
[0048] In summary, when the light source of narrow-band laser filter 21, liquid filter device 22, narrow-band laser filter 23, optical lens 1 31, optical lens 2 32, optical lens 3 33, optical lens 4 51, optical lens 5 52 and optical homogenizing lens 53 is used to treat the human eye, the deep red light band spectrum can accurately stimulate the fovea centralis, and better regulate and control the growth changes of the eye axis; near-infrared light can improve eye microcirculation, increase the supply of nutrients, and help regulate the growth of the eye axis, thereby treating myopia; at the same time, deep red and near-infrared light can penetrate the eyelids into the human eye, and irradiate the retina and choroid evenly and over a large area, so that the treatment subject can be treated with eyes closed.
[0049] Taking into account the convenience of adjusting this type of solar spectrum myopia light meter, a rotating pan-tilt platform 55 is installed at the bottom of the homogenizing and shaping component 5. Through the adjustment device of the rotating pan-tilt platform 55, such as motors and other mechanical equipment, a wide range of adjustment of the pitch angle and azimuth angle of the rotating pan-tilt platform 55 can be achieved. The pitch angle adjustment range is -90° to 90°, and the range angle adjustment range is 0° to 270°.

[0051] Specifically, the detector 54 monitors the energy of the output light spot 512 and feeds back to the energy monitoring module 65, so as to count the total output light power, beam energy intensity and beam power density of the output light spot 512. The energy monitoring module 65 performs statistics based on the monitoring information of the detector 54 and feeds back to the feedback control module 66 for decision-making, and then transmits the decision-making result to the system master control module 63, and the system master control module 63 issues a control instruction to the continuous spectrum power supply module 61 and the circulating liquid control module 62, so as to adjust the radiated light power of the light source component 1 and the spectral characteristics and energy attenuation factor of the filter component 2.
[0052] At the same time, the interaction and control of this type of solar spectrum myopia light meter is realized through the human-computer interaction module 64, specifically: the human-computer interaction module 64 inputs the control command and transmits it to the system master control module 63, and the system master control module 63 issues a control instruction to the continuous spectrum power supply module 61, the circulating fluid control module 62 and the control device of the rotating pan-tilt head 55 according to the control command, so as to realize the radiation power of the continuous spectrum light source component 1, the temperature, flow, spectral bandwidth and optical transmittance of the composite filter component 2, the radiation angle, radiation time and other parameter control of the rotating pan-tilt head 55 and the status monitoring of the entire device.
