In order to achieve the function of relieving the eyestrain of the user, in the related art, a light supplying instrument for emitting light with a predetermined wavelength to irradiate the eyes of the user is provided, and when the light with the predetermined wavelength irradiates the eyes of the user, the blood circulation of the eyes of the user can be accelerated, thereby achieving the function of relieving the eyestrain of the user. However, since the light output by the light feeding instrument is relatively fixed, in order to ensure the light feeding effect of the light feeding instrument on the user, the light feeding instrument requires that the user should aim at the light emitting part of the light feeding instrument when using the light feeding instrument, and the relative position between the user and the light feeding instrument should be kept as constant as possible, which is inconvenient to use and low in comfort, and the user cannot take care of other things such as learning or working during the use of the light feeding instrument.

Based on this, the embodiment of the application discloses a light-feeding device, which can feed light to the environment according to the parameters of the environment light where the light-feeding device is located, so as to feed light to the user in the environment, thereby achieving the effect of conveniently relieving the eye fatigue of the user in daily life, and simultaneously, the user does not need to align the eyes of the user with the light-feeding device, so that the use is convenient and the use comfort is higher.

Therefore, in the present application, the light emitting member 12 is used to emit light having at least one of the first wavelength band, the second wavelength band, the third wavelength band, and the fourth wavelength band, so that the light emitted from the light emitting member 12 can achieve a function of alleviating eye fatigue.

In addition, because the light-feeding device 1 provided by the application is used for feeding light to the environment where the light-feeding device 1 is located, when the user uses the light-feeding device 1, the user can feed light to the environment where the user is located through the light-feeding device 1 only by placing the light-feeding device 1 around the user, the user does not need to align the eyes of the user with the light-feeding device 1, and the use convenience and the use experience are high.

Alternatively, the light-feeding device 1 may include, but is not limited to, any one of a light-feeding instrument, a wearable device, a terminal device, a game machine, a lighting lamp, a storage box, glasses, a stereo, or a toy, wherein the wearable device may include a watch, a bracelet, glasses, or the like, the mobile terminal may include a mobile phone, a tablet, a computer, a family education machine, or the like, the lighting lamp may include a desk lamp, an indoor atmosphere lamp, a ceiling lamp, or the like, and by integrating the function of feeding light to the environment onto an article in daily use, the light-feeding function of the light-feeding device 1 can be facilitated for a user in daily life, for example, when the user sits at a desk for reading and writing, the light-feeding device 1 including any one of a desk lamp, an indoor lighting lamp, a child tablet, a family education machine, or the like can be used for feeding light to the user.

Further, the device body 10 may be a part formed as a main shape structure of the lighting device 1, such as a housing of the lighting device 1 or a base of the lighting device 1, etc. For example, when the light-feeding device 1 is a light-feeding instrument, the device body 10 may be a housing of the light-feeding instrument; when the light-feeding device 1 is a watch, the device body 10 may be a dial case of the watch or a wristband; when the light-feeding device 1 is a home teaching machine, the device body 10 may be a housing of the home teaching machine.

Illustratively, as shown in fig. 2, the light-feeding device 1 is taken as an example of a storage box, the device body 10 is a housing of the storage box, the device body 10 can be used for a user to access glasses, food, medicine, coins, books, stationery, toys, and the like, the light-emitting member 12 is provided on the device body 10, and the light sensor (not shown) is provided inside the device body 10.

Next, the structure and function of each component included in the light-feeding device 1 will be described in detail with reference to the drawings.

Referring to fig. 1 again, in some embodiments, a light intensity threshold may be stored in the circuit board 13, the ambient light information detected by the light sensor 11 may include a light intensity value of the ambient light with a predetermined wavelength, and the circuit board 13 is configured to increase the light intensity of the light with the predetermined wavelength emitted by the light emitting element 12 when the light intensity value is smaller than the light intensity threshold. It can be understood that, in a real environment, when the light intensity value of the light with the predetermined wavelength is lower than the light intensity threshold, the light with the predetermined wavelength received by the user's eyes from the environment is small in ratio and low in intensity, and it is difficult to achieve the effect of alleviating the eye strain of the user, therefore, it is necessary to emit the light with the predetermined wavelength to the environment through the nursing light device 1 to enhance the light intensity of the light with the predetermined wavelength in the environment, so that the environment light irradiating the user's eyes can achieve the effect of alleviating the eye strain of the user, that is, when the light intensity value of the light with the predetermined wavelength in the environment light is lower than the light intensity threshold, the circuit board 13 is used to control the light emitting member 12 to emit light to nurse the environment where the nursing light device 1 is located, so that the environment where the nursing light device 1 is located is maintained in a state where the light intensity value of the light with the predetermined wavelength reaches the light intensity threshold, so as to realize the function of the light feeding equipment 1 for feeding light to the environment, and the effect of relieving the eyestrain of the user can be realized by the environment light irradiated into the eyes of the user.

Optionally, the light intensity threshold may include at least one of a first threshold, a second threshold, a third threshold and a fourth threshold, the first threshold is a light intensity threshold of light with a first wavelength band, the second threshold is a light intensity threshold of light with a second wavelength band, the third threshold is a light intensity threshold of light with a third wavelength band, and the fourth threshold is a light intensity threshold of light with a fourth wavelength band. Correspondingly, the light intensity value may include at least one of a first value, a second value, a third value and a fourth value, where the first value is a light intensity value of the ambient light with a first wavelength band, the second value is a light intensity value of the ambient light with a second wavelength band, the third value is a light intensity value of the ambient light with a third wavelength band, and the fourth value is a light intensity value of the ambient light with a fourth wavelength band. By respectively storing the first threshold, the second threshold, the third threshold and the fourth threshold in the circuit board 13, and respectively detecting the first value, the second value, the third value and the fourth value in the ambient light through the optical sensor 11, so as to respectively compare the first value with the first threshold, the second value with the second threshold, the third value with the third threshold, and the fourth value with the fourth threshold through the circuit board 13, light can be respectively fed to light with four wave bands, so as to avoid the situation that the light intensity value of the light in any wave band, such as any wave band from the first wave band to the fourth wave band, in the environment is too high due to excessive light feeding to the light with any wave band, such as any wave band from the first wave band to the fourth wave band, thereby avoiding the situation that the eyes of the user may be harmed due to a strong light environment, and improving the safety of the light feeding device 1, or, the situation of insufficient light feeding to the light with partial wave bands is avoided, so as to improve the light feeding effect of the light feeding device 1.

Optionally, the light sensor 11 may be further configured to detect light intensity values of ambient light having at least one of a first wavelength band, a second wavelength band, a third wavelength band and a fourth wavelength band in the ambient light, respectively, to obtain at least one of the first value, the second value, the third value and the fourth value in the parameter of the ambient light. In other embodiments, the light sensor 11 may be further configured to detect parameters such as a spectral distribution, a peak width, an illuminance, an optical power, and an optical density of the ambient light, so that at least one of the first value, the second value, the third value, and the fourth value of the parameter in the ambient light can be calculated by the circuit board 13.

In some embodiments, there may be one or more glowing members 12. In an optional example, the number of the light-emitting members 12 is one, so that the light-feeding device 1 can be provided with the light-feeding function, and the number of the light-emitting members 12 can be reduced, thereby reducing the manufacturing cost of the light-feeding device 1. In another alternative example, as shown in fig. 2 and 3, the number of the light-emitting members 12 is multiple, the multiple light-emitting members 12 are disposed at the device main body 10 at intervals, and the total light intensity of the light emitted by the light-emitting members 12 can be enhanced by providing multiple light-emitting members 12, so that the total light intensity of the light emitted by the light-emitting members 12 can easily meet the use requirement under the condition that the light intensity value of the ambient light is extremely low, the function of increasing the light intensity value of the ambient light to be higher than the light intensity threshold value can be realized, and the use performance of the lighting device 1 is good. Alternatively, the plurality of light emitting members 12 may be distributed in a row, distributed in a ring, or distributed in an array on the apparatus body 10 according to different use requirements.

In some embodiments, the light emitted from the light emitting element 12 with a predetermined wavelength may have a total color temperature T, the color temperature of the light emitted from the light emitting element 12 is too low, and the user feels too comfortable and feels sleepy, and the learning and working efficiency is reduced, and the color temperature of the light emitted from the light emitting element 12 should not be too low, and meanwhile, in order to avoid the color temperature of the light emitted from the light emitting element 12 being too high, which may cause damage to the eyes of the user, the color temperature of the light emitted from the light emitting element 12 should not be too high, and therefore, the total color temperature T may satisfy: 3500K ≦ T ≦ 6500K, for example, the total color temperature T may be: 3500K, 4000K, 4500K, 5000K, 5500K, 6000K or 6500K, etc.

In some embodiments, the light emitting element 12 may emit light having a predetermined wavelength and a total intensity E, which should not be too low in order to allow the light emitting element 12 to emit light to function as a light source for the environment, and which should not be too high in order to prevent the light emitting element 12 from emitting light to damage the eyes of the user, so that the total intensity E may satisfy: 300Lux ≦ E ≦ 800Lux, for example, the total light intensity E may be: 300Lux, 350Lux, 400Lux, 450Lux, 500Lux, 550Lux, 600Lux, 650Lux, 700Lux, 750Lux, 800Lux, or the like.

Further, the light emitted from the light emitting element 12 at least includes light having a first wavelength band, a second wavelength band and a third wavelength band, and in order to allow the light emitting element 12 to simultaneously provide light having the three wavelength bands to the environment, the light having each wavelength band emitted from the light emitting element 12 should have a certain ratio in the total light, and at the same time, since the difference in light intensity of the light having the three wavelength bands in the environment is not large in general, the ratio of the light having each wavelength band emitted from the light emitting element 12 in the total light should not be too large. Based on this, the light having the first wavelength band may have the first light intensity E1, and the first light intensity E1 may satisfy: the 10% E.ltoreq.E 1.ltoreq.40% E, for example, the first light intensity E1 may be 10% E, 15% E, 20% E, 25% E, 30% E, 35% E, or 40% E, etc., the light having the second wavelength band may have a second light intensity E2, and the second light intensity E2 may satisfy: the 10% E2E 40E, for example, the second light intensity E2 may be 10% E, 15% E, 20% E, 25% E, 30% E, 35% E, or 40% E, etc., the light having the third band may have a third light intensity E3, and the third light intensity E3 may satisfy: 10% E.ltoreq.E 3.ltoreq.40% E, for example, the third light intensity E3 may be 10% E, 15% E, 20% E, 25% E, 30% E, 35% E, 40% E, or the like.

From the foregoing, the light having the fourth wavelength band belongs to infrared light, in order to avoid that the light intensity of the infrared light in the ambient light is too large and causes harm to the human body of the user, the light having the fourth wavelength band may have a smaller percentage in the total light, and meanwhile, when the environment needs to be fed with the light having the fourth wavelength band, in order to achieve the feeding effect of the feeding light device 1, the light having the fourth wavelength band should have a certain percentage in the total light, based on which, the light having the fourth wavelength band may have a fourth light intensity E4, and the fourth light intensity E4 may satisfy: 0% E < E4 ≦ 40% E, for example, the fourth intensity E4 may be 0% E, 5% E, 10% E, 15% E, 20% E, 25% E, 30% E, 35% E, or 40% E, and so forth.

Further, in order to maximize the effect of relieving the user's eye fatigue of the light emitted from the light emitting member 12, the light emitted from the light emitting member 12 may be all light having a predetermined wavelength, that is, the first light intensity E1, the second light intensity E2, the third light intensity E3 and the fourth light intensity E4 may satisfy: e1+ E2+ E3+ E4 ═ E.

Alternatively, the light emitting member 12 may emit light having a plurality of wavelength bands among the first, second, third, and fourth wavelength bands at the same time, or the light emitting member 12 may emit light having only one wavelength band among the first, second, third, and fourth wavelength bands at the same time. Next, specific structures of the several kinds of light emitting members 12 will be described, and the several kinds of light emitting members 12 can simultaneously emit light having a plurality of wavelength bands among the first wavelength band, the second wavelength band, the third wavelength band, and the fourth wavelength band. In an alternative embodiment, as shown in fig. 3, the light emitting member 12 may include a plurality of sub-light emitting members 120, each sub-light emitting member 120 may be configured to emit light having any one of a first wavelength band, a second wavelength band, a third wavelength band and a fourth wavelength band, so that light having different wavelength bands can be emitted through a plurality of sub-light emitting member 120 groups, respectively, so that the light emitting member 12 can emit the light having the different wavelength bands at the same time, the plurality of sub-light emitting members 120 may be distributed in a row, a in fig. 3 simply shows an example in which the light emitting member 12 is composed of two sub-light emitting members 120, wherein the two sub-light emitting members 120 are configured to emit light having any two different frequency bands among the first frequency band to the fourth frequency band, respectively, the two sub-light emitting members 120 are distributed in a row, b in fig. 3 simply shows an example in which the light emitting member 12 is composed of three sub-light emitting members 120, wherein, the three sub-luminous members 120 are configured to respectively emit light beams having any three different frequency bands from the first frequency band to the fourth frequency band, and the three sub-luminous members 120 are distributed in a ring shape, and c in fig. 3 simply shows an example that the luminous member 12 is composed of four sub-luminous members 120, wherein the four sub-luminous members 120 are configured to respectively emit four light beams having the first frequency band to the fourth frequency band, and the four sub-luminous members 120 are distributed in an array.

Alternatively, the sub-luminous members 120 may be light emitting diodes capable of emitting light having any one of the first, second, third and fourth wavelength bands, thereby enabling the luminous members 12 to be low in power consumption and small in size.

Referring to fig. 1 again, in another alternative embodiment, the light emitting element 12 may include a light emitting diode (not shown) for emitting light with a first wavelength, and a surface of the light emitting diode is covered with a fluorescent material (not shown) capable of generating light with at least one of a second wavelength band, a third wavelength band and a fourth wavelength band under excitation of the light with the first wavelength. In an alternative example, the fluorescent material includes a phosphor coated on a surface of the light emitting diode, and the phosphor is configured to be excited by the light having the first wavelength to emit the light having at least one of the second wavelength band, the third wavelength band and the fourth wavelength band, for example, the phosphor may include two red phosphors, and the two red phosphors can emit red lights having the second wavelength band and the third wavelength band, respectively, when being excited by the light having the first wavelength, so that the light emitting member 12 can emit the light having the first wavelength band, the second wavelength band and the third wavelength band at the same time. In another alternative example, the fluorescent material includes a quantum dot film, the quantum dot film is disposed on the periphery of the light emitting diode, and the quantum dot film is configured to be excited by the light with the first wavelength to emit the light with at least one of the second wavelength band, the third wavelength band and the fourth wavelength band.

In some embodiments, the light emitting member 12 can emit only light with at least two of the first, second, third and fourth wavelength bands at the same time, that is, the light emitting member 12 can be used to emit light with at least two of the first, second, third and fourth wavelength bands, respectively, so as to perform a light feeding function with light of a plurality of wavelength bands of the first, second, third and fourth wavelength bands to the environment for a period of time.

For example, the light emitting member 12 may include a light emitting diode and a filtering electrochromic film (none of which is shown), the light emitting diode may be configured to emit light rays covering a plurality of wavelength bands of a first wavelength band, a second wavelength band, a third wavelength band, or a fourth wavelength band, the filtering electrochromic film is disposed on an outer circumference of the light emitting diode, the filtering electrochromic film is configured to be transparent when being disconnected from a current, and change color when being powered, so as to filter light rays emitted from the light emitting diode, such that light rays having any one of the first wavelength band, the second wavelength band, the third wavelength band, or the fourth wavelength band of the light emitting diode are transmitted through the filtering electrochromic film. Further, since the color of the filter electrochromic film is different when the voltage applied to the filter electrochromic film is different, the color of the filter electrochromic film can be changed by changing the voltage applied to the filter electrochromic film through the circuit board 13, so as to change the wavelength band of the light that can pass through the filter electrochromic film, so that the light emitting member 12 can emit light having a plurality of wavelengths among the first wavelength band, the second wavelength band, the third wavelength band, and the fourth wavelength band, respectively. It can be understood that, the light filter electrochromic film is adopted to control the wave band that the light emitted by the light emitting member 12 has, the light emitted by the light emitting member 12 can have more modes, that is, not only can the light emitting member 12 emit the light with the appointed wave band under the condition of applying voltage to the light filter electrochromic film, but also can not apply voltage to the light filter electrochromic film, so that the light filter electrochromic film keeps transparent, so that the light emitted by the light emitting diode is completely transmitted, the light emitting mode of the light emitting member 12 is various, and the light emitting device can be adapted to more use requirements.

Optionally, the frequency f of the light emitting member 12 switching the light with different wavelengths is set to be f, so as to avoid harmful stroboflash generated when the light emitting member 12 switches between the light with different wave bands, which may lead to visual fatigue, eye flower, nausea and headache of the user, the frequency f may satisfy: f is more than or equal to 24Hz or less than or equal to 3Hz, for example, the frequency f can be 24Hz, 75Hz, 300Hz, 2000Hz, 5000Hz or 10000Hz, etc., or the frequency f can be 3Hz, 2Hz, 0.8Hz, 0.03Hz, 0.002Hz, etc. It can be understood that, when the luminous element 12 is used as an illumination light source, in order to avoid the illumination light source from strobing and causing injury to the user, and further ensure the safety of the nursing light device 1, it is preferable that the frequency f should satisfy: f is not less than 3152Hz or not more than 3Hz, for example, the frequency f can be 3152Hz, 4000Hz, 4500Hz, 6000Hz or 12000Hz, or the frequency f can be 3Hz, 2Hz, 0.8Hz, 0.03Hz, 0.002Hz, etc.

Optionally, at this time, the light emitting member 12 may have a light emitting period t, in order to enable the light emitting member 12 to implement the light supply of the light with the three wavelength bands to the environment, the time lengths of the light emitting members 12 emitting the light with the three wavelength bands respectively should have a certain ratio in the light emitting period t, and meanwhile, since the light intensity difference of the light with the three wavelength bands in the environment is not large in general, the ratio of the light emitting members 12 emitting the light with the wavelength bands respectively should not be too large in the light emitting period t. Based on this, in one light emitting period t, the total duration of the light emitting element 12 emitting the light with the first wavelength band may be t1, and the total duration t1 may satisfy: 10% t1 t 40% t, for example, the total time period t1 of the light emitting element 12 emitting light with the first wavelength band may be 10% t, 15% t, 20% t, 25% t, 30% t, 35% t, 40% t, etc., the total time period t2 of the light emitting element 12 emitting light with the second wavelength band may be t2, and the total time period t2 may satisfy: 10% t2 t 40% t, for example, the total time t2 of the light emitting element 12 emitting light with the second wavelength band may be 10% t, 15% t, 20% t, 25% t, 30% t, 35% t, 40% t, etc., the total time t3 of the light emitting element 12 emitting light with the third wavelength band may be t3, and the total time t3 may satisfy: 10% t3 t 40 t, for example, the total time t3 of the light emitting member 12 emitting the light having the third wavelength band may be 10% t, 15% t, 20% t, 25% t, 30% t, 35% t, 40% t, or the like.

It can be understood that the light ray with the fourth wavelength band belongs to the infrared light ray, in order to avoid that the intensity of the infrared light ray in the ambient light is too large, which may cause visual fatigue, eye flower or even nausea and headache of the user, the duration of the light feeding with the light ray with the fourth wavelength band by the luminous member 12 may be short, and at the same time, when the light feeding with the light ray with the fourth wavelength band is needed to the environment, in order to achieve the light feeding effect of the light feeding device 1, the light ray with the fourth wavelength band should have a certain light feeding duration, based on which the total duration of the light ray with the fourth wavelength band emitted by the luminous member 12 may be t4, and the total duration t4 may satisfy: 0% t < t4 ≦ 40% t, for example, the total time t4 of the light emitting element 12 emitting light with the fourth wavelength band may be 0% t, 5% t, 10% t, 15% t, 20% t, 25% t, 30% t, 35% t, 40% t, etc.

Further, in order to maximize the effect of relieving the user's eye fatigue of the light emitted from the light emitting member 12, the light emitting member 12 may be used only for emitting the light having the predetermined wavelength, that is, the total time period t1 for emitting the light having the first wavelength band, the total time period t2 for emitting the light having the first wavelength band, the total time period t3 for emitting the light having the first wavelength band, and the total time period t4 for emitting the light having the first wavelength band may satisfy: t1+ t2+ t3+ t4 ═ t.

It can be understood that the ratio of the total light intensity E of the light emitted by the luminous element 12 in each wavelength band is the ratio of the total light intensity E of the light emitted by the luminous element 12, or the respective duration of the light emitted by the luminous element 12 in each wavelength band within one light emitting period t of the luminous element 12 can be adjusted by the circuit board 13 according to the ambient light parameters, so as to more accurately realize the light feeding process of the light feeding device 1 to the environment, so that the light intensity value of the light with the predetermined wavelength in the environment is kept in a state higher than the light intensity threshold value, and at the same time, the light feeding device 1 is prevented from excessively feeding light to the environment, so as to avoid the situation that the light intensity in the environment is too high to cause damage to the eyes of the user, thereby improving the safety of the use of the light feeding device 1.
