  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  An illumination system shown as an embodiment of the present invention is configured as shown in FIG. 1, for example. This illumination system includes a visual function selection unit (visual function selection unit) 1, a level input unit (input unit) 2, an illumination setting unit (illumination setting unit) 3, an illumination control unit (illumination control unit) 4, and an illumination unit (illumination). Means) 5.

  The visual function selection unit 1 selects at least one of visual acuity, visual field, contrast sensitivity, and stereoscopic vision as visual functions related to human appearance. This visual function is not limited to visual acuity, visual field, contrast sensitivity, and stereoscopic vision. That is, the visual function may be a function related to human appearance. The visual function selection unit 1 may select a single visual function or a plurality of visual functions. The visual function selection unit 1 receives input operations such as buttons operated by the user. The button or the like is only required to be able to select a visual function that the user desires to improve. The visual function selection unit 1 determines that at least one of visual acuity, visual field, contrast sensitivity, and stereoscopic vision is selected according to the operation content. Further, the visual function selection unit 1 is not limited to an operation device such as a button.

  The level input unit 2 inputs the degree of improvement of each visual function selected by the visual function selection unit 1. The level input unit 2 inputs the degree of improvement for each visual function selected by the visual function selection unit 1. The level input unit 2 receives input operations such as direction keys and buttons operated by the user. The direction keys and buttons only need to be able to input the degree of improvement of each visual function.

  The illumination setting unit 3 acquires information indicating each visual function selected by the visual function selection unit 1. The illumination setting unit 3 sets an illumination element in association with the visual function selected by the visual function selection unit 1. Thereby, the illumination setting part 3 sets the illumination element for improving each selected visual function. This lighting element includes illuminance, irradiation range, color temperature, light uniformity, and the like. Of course, the illumination element may be another element as long as it can identify illumination light. In addition, as shown in FIG. 2, the illumination setting unit 3 may refer to table data in which each visual function is associated with each illumination element.

  When the selected visual function is visual acuity, the illumination setting unit 3 sets illuminance as an illumination element. When the selected visual function is a visual field, the illumination setting unit 3 sets an irradiation range as an illumination element. When the selected visual function is contrast sensitivity, the illumination setting unit 3 sets a color temperature as an illumination element. When the selected visual function is stereoscopic vision, the illumination setting unit 3 sets light uniformity as an illumination element.

  The illumination control unit 4 controls the illumination elements set by the visual function selection unit 1 by the output amount that realizes the improvement degree of the visual function input by the level input unit 2. When the selected visual function is visual acuity, the illumination control unit 4 controls to increase the illuminance as the output amount. When the selected visual function is a visual field, the illumination control unit 4 controls to widen the irradiation range as the output amount. When the selected visual function is contrast sensitivity, the illumination control unit 4 controls to increase the color temperature as the output amount. When the selected visual function is stereoscopic vision, the illumination control unit 4 controls to increase the uniformity of light as an output amount. In addition, when the illumination control part 4 raises the uniformity of illumination light, it is desirable to control so that even if it reduces the whole illumination intensity, unevenness of illumination intensity is eliminated.

  The illumination unit 5 emits illumination light controlled by the illumination control unit 4. The illumination unit 5 has a configuration in which illumination elements of illumination light can be adjusted. As described above, when the selectable visual function is visual acuity, visual field, contrast sensitivity, or stereoscopic vision, the illumination unit 5 has such selectable illuminance, irradiation range, color temperature, or light uniformity. It has an adjustable configuration. That is, the illumination unit 5 only needs to adjust the illumination element corresponding to the visual function selected by the visual function selection unit 1.

  The illumination unit 5 includes a light source that emits illumination light such as an LED. The illumination part 5 may be comprised with the some light source, and may be comprised with the single light source.

  As a configuration for adjusting the illuminance, the illuminator 5 may be capable of changing the illuminance of a single light source, or may be capable of adjusting the number of light sources to be driven. The illumination unit 5 may be configured to adjust the irradiation range, the spread of illumination light by a single light source may be adjustable, and the number and position of the driving light sources may be adjustable. The illumination unit 5 may be configured to adjust the color temperature, the color temperature of a single light source may be adjustable, or the color temperature may be adjustable by a combination of illumination lights having different color temperatures. The illumination unit 5 may be adjustable by a single light source as a configuration for adjusting the uniformity of the light, or may be adjustable by the number and position of the light sources to be driven.

  As described above, according to this lighting system, when an arbitrary visual function and an improvement degree are input, the input degree of improvement is controlled by controlling the output amount of the lighting element associated with the arbitrary visual function. The illumination unit 5 is controlled so as to realize the above. That is, the illumination system sets input parameters from the viewpoint of visibility (visual function) such as readability of characters and the like, color reproducibility, field of view range, and recognition of unevenness. The lighting system automatically converts the visual function as an input parameter into a lighting element to adjust the illumination light. Therefore, according to this illumination system, it is possible to adjust the illumination light so that it is easy for the user to see the object, depending on the way the user sees and the usage of illumination.

  Moreover, according to this illumination system, the illumination unit 5 can be controlled not by the operation of the physical parameters of the illumination unit 5 but by the degree of improvement in visual function. Thereby, the change of the appearance by the illumination part 5 can be operated intuitively. In other words, according to the lighting system, the lighting unit is not allowed to select a physical parameter of a lighting element such as a light control parameter or a color control parameter such as illuminance or color temperature, but to intuitively select a user's appearance. 5 can be controlled.

  In addition, the lighting system associates a single lighting element with each selectable visual function. That is, according to the illumination system, the visual function and the illumination element are associated one-to-one. This is because the relationship between the visual function and the illumination element is clarified such as visual acuity and illuminance, contrast sensitivity and color temperature, visual field and irradiation range, stereoscopic vision and uniformity. Thereby, according to the illumination system, even if the improvement degree of any visual function is changed, it is possible to suppress the lighting elements of other visual functions from changing.

  Furthermore, this lighting system can simultaneously control not only lighting elements corresponding to one visual function but also lighting elements corresponding to two or more visual functions. In addition, the lighting system may register two or more visual functions as a group. Thereby, the illumination system can improve the illumination elements such as the illuminance corresponding to the visual acuity and the irradiation range corresponding to the visual field at the same time in order to improve the visual acuity and the visual field, for example.

  As shown in FIG. 3, the lighting system described above includes a parameter storage unit (storage unit) that stores at least one of the visual function selected by the visual function selection unit 1 and the degree of improvement input by the level input unit 2. ) 6 may be provided. The parameter storage unit 6 may store the visual function and / or improvement level each time the visual function selection unit 1 or the level input unit 2 selects and inputs the visual function and / or improvement level. Further, the parameter storage unit 6 may register the visual function and / or improvement degree only when an operation for registering the visual function and / or improvement degree is received by the user.

  The illumination setting unit 3 inputs the visual function stored by the parameter storage unit 6. The illumination setting unit 3 sets illumination elements using the input visual function. The illumination control unit 4 inputs the improvement degree stored by the parameter storage unit 6 and controls the output amount of the illumination element using the input improvement degree. Thereby, the illumination control part 4 drives the illumination part 5 according to the set illumination element and the improvement degree of the said illumination element.

  As described above, according to the illumination system, the provision of the parameter storage unit 6 can store the visual function and / or improvement degree for realizing an illumination environment in which a user can easily see an object. As a result, the lighting system can instantly call up an illumination environment in which an object is easy for the user to see and control the illumination light.

  The illumination system described above may include an age input unit (age input means) 7 and an age-specific adjustment unit (adjustment means) 8, as shown in FIG. Although the parameter storage unit 6 is not shown in FIG. 4, it may be connected to the visual function selection unit 1 and / or the level input unit 2.

  The age input unit 7 inputs the user's age. The age input part 7 consists of operation devices, such as a button and a dial, for example. The age input unit 7 supplies the input age to the age-specific adjustment unit 8.

  The age-specific adjustment unit 8 adjusts the output amount of the lighting element according to the age to which the age input by the age input unit 7 belongs. The age-specific adjustment unit 8 stores a correspondence relationship between the age, the age range, and the adjustment amount of the lighting element. For example, when an age of 60 to 69 is input, the age-specific adjustment unit 8 determines that it is in its 60s. Thereby, the adjustment part 8 classified by age adjusts the output amount of the illumination element controlled by the illumination control part 4 so that it may respond to the change of the visual function by the input age. The age-specific adjustment unit 8 adjusts the output amount of each lighting element at an arbitrarily set ratio in consideration of the performance of the visual function due to growth or aging.

  For example, since an elderly person feels a darker field of view than an adult, the age-specific adjustment unit 8 sets an adjustment amount that doubles the illuminance as a lighting element in the case of a user who is 60 years of age or older. Moreover, the adjustment part 8 according to the age arbitrarily adjusts the adjustment amount (2 times, 3 times, 0.5 times, etc.) of each lighting element (illuminance, irradiation range, color temperature, uniformity) with respect to the age. May be set.

  As described above, according to this lighting system, if the user intuitively inputs the visual function and / or improvement degree, even if the visual function varies depending on the age, the lighting environment is easy for the user to see the object. The output amount of the lighting element can be adjusted.

  As shown in FIG. 5, the lighting system described above includes a user setting unit (user setting unit) 9, a user detection unit (user detection unit) 10, a user rank setting unit (user rank setting unit) 11, and a user-specific parameter storage unit. 12 may be provided.

  The user setting unit 9 sets a user who uses the lighting system in advance. The user setting unit 9 sets a user based on, for example, an ID.

  The user detection unit 10 detects the user set by the user setting unit 9. This user detection part 10 detects a user automatically, for example using a camera etc. Moreover, the user detection part 10 may detect a user with operation devices, such as a button, for example. When detecting the user, the user detection unit 10 supplies an ID for identifying the user to the user rank setting unit 11.

  The user rank setting unit 11 sets user priorities when a plurality of users are detected by the user detection unit 10. In the user rank setting unit 11, for example, a priority rank is set in advance by a user operation. The user rank setting unit 11 supplies the ID of the main user having the highest priority among the plurality of users to the parameter storage unit 12 for each user.

  Similar to the parameter storage unit 6 described above, the user-specific parameter storage unit 12 stores the visual function and / or the degree of improvement. The user-specific parameter storage unit 12 associates the user's ID with the stored visual function and / or degree of improvement.

  The illumination setting unit 3 inputs the visual function stored by the user-specific parameter storage unit 12 corresponding to a user with a high priority. The illumination setting unit 3 sets illumination elements using the input visual function. Moreover, the illumination control part 4 inputs the improvement degree preserve | saved by the parameter storing part 12 classified by user corresponding to a user with a high priority. The illumination control unit 4 controls the output amount of the illumination element using the input improvement degree.

  As described above, according to this illumination system, it is possible to automatically detect a user and provide an illumination environment in which the user can easily see an object.

  Furthermore, in this lighting system, as shown in FIG. 6, the visual function selection unit 1, the level input unit 2, the lighting setting unit 3, and the lighting control unit 4 may be configured by an information terminal 20. As this information terminal 20, a personal computer, a smart phone, a mobile phone, etc. are mentioned. In addition, the information terminal 20 may include a wireless communication unit (not shown). The information terminal 20 can control the output amount of the illumination element in the illumination unit 5 by transmitting a control signal to the illumination unit 5 by the wireless communication unit. According to this illumination system, the illumination unit 5 can be remotely operated by the information terminal 20.

  The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made depending on the design and the like as long as the technical idea according to the present invention is not deviated from this embodiment.
