[0057] So far, the hardware structure and functions of the relevant devices of the present invention have been described in detail. Next, various embodiments of the present invention will be proposed based on the above hardware structure and functions.

[0058] Firstly, the present invention proposes an illumination adjustment method.

[0059] Please refer to Figure 2 , is a flow chart of the illumination adjustment method embodiment 1 of the present invention. In this embodiment, according to different requirements, Figure 2 The execution order of the steps in the flowchart shown may be changed, and some steps may be omitted.

[0060] In this embodiment, the illumination adjustment method includes:

[0061] Step S110, querying a preset light intensity E0 of a light source at a preset position.

[0062] In this embodiment, the lighting device 1 is used in the user's home, such as a living room, bedroom, study, etc. The device can be a smart lamp such as a desk lamp, ceiling lamp, chandelier, etc., which is mainly used to provide lighting services for users to meet their learning and living needs. The preset position refers to a position frequently used by the user near the lighting device 1, such as a desk in a study, a dressing table in a bedroom, a dining table and a coffee table in a living room, a sofa and a coffee table in an entertainment room, etc.

[0063] Generally, the light sources of the lighting devices 1 at different positions are preset with different preset light intensities E0. Specifically, the lighting modes of the lighting device 1 can be classified and set in advance, and the lighting modes may include, but are not limited to, reading mode, rest mode, dining mode, and entertainment mode. Among them, different lighting modes are preset with different brightness and / or light intensity, and the brightness and / or light intensity are used to meet the user's lighting needs for reading, resting, dining and entertainment respectively. For example, usually, the optimal light intensity for users to read is 600cd (cd: candela), the optimal light intensity for users to rest is 400cd, the optimal light intensity for users to dine is 800cd, and the optimal light intensity for users to entertain is 1000cd. Therefore, in this embodiment, when the lighting mode is a reading mode, the preset light intensity E0 of the lighting device 1 can be set to 600 cd (cd: candela); when the lighting mode is a rest mode, the preset light intensity E0 can be set to 400 cd; when the lighting mode is a dining mode, the preset light intensity E0 can be set to 800 cd; when the lighting mode is an entertainment mode, the preset light intensity E0 can be set to 1000 cd.

[0064] In this embodiment, the lighting device 1 can query the preset light intensity E0 of the light source of the lighting device 1 in real time or at a fixed time. In another embodiment, before querying the preset light intensity E0 of the light source, the lighting device 1 can also query the current lighting mode of the lighting device 1, and the current lighting mode at least includes reading mode, rest mode, dining mode, and entertainment mode; and then query the preset light intensity E0 in the corresponding lighting mode. In addition, in another embodiment, the lighting device 1 can also be connected to a camera, and the above-mentioned steps of querying the current lighting mode of the lighting device 1 and the preset light intensity E0 in the corresponding lighting mode are performed when and only when the camera captures the user image at the preset position.

[0065] Step S120: detecting a first actual light intensity E1 at a preset position.

[0066] As described above, the preset position is a position frequently used by users near the lighting device 1. In this embodiment, at least one light intensity detector, such as a light intensity detector, a light intensity tester, a light illuminance meter, etc., may be arranged at the preset position to detect the actual light intensity at the preset position. The actual light intensity may include the first actual light intensity E1.

[0067] Step S130: comparing the preset light intensity E0 with the first actual light intensity E1.

[0068] In this embodiment, after obtaining the first actual illumination intensity E1 of the preset position, the first actual illumination intensity E1 can be compared with the preset illumination intensity E0 to determine whether the actual illumination intensity of the preset position meets the preset optimal illumination intensity. For example, if the illumination mode of the illumination device 1 is the reading mode, the preset illumination intensity E0 of the illumination device 1 queried above is generally 600cd. At this time, if the first actual illumination intensity E1 detected is 300cd, the embodiment can compare 600cd with 300cd to determine whether the actual illumination intensity of the preset position is consistent with the expected situation. That is, compare whether there is a large difference between the preset illumination intensity E0 and the first actual illumination intensity E1, and whether the two are inconsistent.

[0069] Step S140, calculating a power adjustment value P according to the comparison result, a height h between the light source and the preset position plane, and an angle β between the light source direction and the vertical direction.

[0070] like Figure 3 As shown, it is a schematic diagram of the light source illumination provided in this embodiment. It can be seen from the figure that the plane perpendicular to the illumination direction of the light source of the lighting device 1 is N, and the preset position plane where the user is located is H, the preset light intensity of the preset position is E0, the first actual light intensity is E1, the height of the light source of the lighting device 1 and the preset position plane H is h, the default illumination power of the light source is p0, the luminous efficiency parameter is k, and the angle between the light source direction and the vertical direction is β.

[0071] When the preset light intensity E0 and the first actual light intensity E1 are significantly different and inconsistent, it is necessary to adjust the light source output power of the lighting device 1 to reduce or increase the light intensity at the preset position. In this embodiment, the calculation formula of the power adjustment value P is:

[0072]

[0073] Where E0 is the preset light intensity, E1 is the first actual light intensity, h is the height between the light source and the preset position plane, p0 is the default irradiation power of the light source, k is the luminous efficiency parameter of the light source, and θ is the complementary angle of the angle β between the light source direction and the vertical direction.

[0074] Step S150: adjusting the power value according to the power The lighting power of the light source is adjusted so that the first actual illumination intensity E1 at the preset position is consistent with the preset illumination intensity E0.

[0075] As described above, when the power adjustment value is calculated When the lighting device 1 controls the output power of the light source to adjust, based on the original output power, reduce or increase The output power of the power value, that is, adjust the original output power up or down In other words, if the first actual illumination intensity E1 is less than the preset illumination intensity E0, then the power value P is increased based on the original output power of the lighting device 1. If the first actual illumination intensity E1 is not less than the preset illumination intensity E0, then the power value P is reduced based on the original output power of the lighting device 1. In this way, the first actual illumination intensity E1 at the preset position is as consistent as possible with the preset illumination intensity E0.

[0076] Through the above steps S110-S150, the illumination adjustment method proposed in the present invention detects the actual light intensity at a preset position, and compares the actual light intensity with the preset optimal light intensity, and then calculates the output power adjustment value of the lighting device that needs to be adjusted through a preset light intensity-power conversion formula, thereby realizing automatic adjustment of the output power of the lighting device and improving the intelligence level of the lighting device and user experience.

[0077] Furthermore, based on the above-mentioned embodiment 1 of the present invention, embodiment 2 of the illumination adjustment method described in the present invention is proposed.

[0078] like Figure 4A-4B FIG. 1 is a flow chart of Embodiment 2 of the illumination adjustment method of the present invention. Figure 4A-4B The execution order of the steps in the flowchart shown may be changed, and some steps may be omitted.

[0079] In this embodiment, the step S130 specifically includes:

[0080] Step S131, calculate the difference between the preset light intensity E0 and the first actual light intensity E1, and determine whether the difference exceeds a preset threshold. If yes, execute step S140; if no, end the process.

[0081] In this embodiment, the standard for judging whether the actual light intensity is consistent with the preset light intensity is: whether the difference between the preset light intensity E0 and the first actual light intensity E1 exceeds a preset threshold. The preset threshold refers to a preset floating range value, that is, the actual light intensity can be higher or lower than the preset light intensity, as long as it does not exceed the range, the light intensity of the two is consistent. Furthermore, when the lighting mode of the lighting device 1 is different, the preset threshold value may also be a different floating range value, for example: when the lighting mode of the lighting device 1 is a reading mode, the preset threshold value is ±70cd, that is, E0∈[E0-70cd, E0+70cd]; when the lighting mode is a rest mode, the preset threshold value is ±50cd, that is, E0∈[E0-50cd, E0+50cd]; when the lighting mode is a dining mode, the preset threshold value is ±90cd, that is, E0∈[E0-90cd, E0+90cd]; when the lighting mode is an entertainment mode, the preset threshold value is ±110cd, that is, E0∈[E0-110cd, E0+110cd].

[0082] The step S140 specifically includes:

[0083] Step S141: adjusting the power value according to the Adjust the lighting power of the light source The power value.

[0084] In this embodiment, when the power adjustment value is calculated When the lighting device 1 controls the output power of the light source to adjust, based on the original output power, reduce or increase The output power of the power value, that is, adjust the original output power up or down In other words, if the first actual illumination intensity E1 is less than the preset illumination intensity E0, then the original output power of the lighting device 1 is increased by If the first actual illumination intensity E1 is not less than the preset illumination intensity E0, then the original output power of the lighting device 1 is reduced by Power value.

[0085] Step S142, detecting a second actual illumination intensity E2 at the preset position.

[0086] As described above, after adjusting the output power of the lighting device 1, this embodiment also needs to re-detect the actual light intensity value of the preset position, that is, detect the second actual light intensity E2 of the preset position to verify whether the actual light intensity value of the preset position is consistent with the preset light intensity value E0.

[0087] Step S143, calculating the difference between the preset light intensity E0 and the second actual light intensity E2, and determining whether the difference exceeds a preset threshold; if so, executing step S144; if not, ending the process.

[0088] In this embodiment, the preset threshold is mainly used to measure whether the preset light intensity E0 and the second actual light intensity E2 are consistent. Therefore, the preset threshold can be consistent with the preset threshold in step S131, that is, when the lighting mode of the lighting device 1 is different, the preset threshold can also be a different floating range value. For example: when the lighting mode of the lighting device 1 is a reading mode, the preset threshold is ±70cd, that is, E0∈[E0-70cd, E0+70cd]; when the lighting mode is a rest mode, the preset threshold is ±50cd, that is, E0∈[E0-50cd, E0+50cd]; when the lighting mode is a dining mode, the preset threshold is ±90cd, that is, E0∈[E0-90cd, E0+90cd]; when the lighting mode is an entertainment mode, the preset threshold is ±110cd, that is, E0∈[E0-110cd, E0+110cd].

[0089] Step S144, the adjusted light source illumination power is adjusted again to a power value of ±0.036p0.

[0090] In this embodiment, when the second actual light intensity E2 is inconsistent with the preset light intensity E0, it means that the first adjustment is not in place. However, since a relatively large power adjustment has been made once, it is not appropriate to make a large power adjustment again. In addition, it is found through research that after the first large power adjustment, only a small power adjustment is needed to make the actual light intensity provided by the adjusted lighting device 1 close to or even consistent with the preset light intensity E0.

[0091] Therefore, in this embodiment, when it is found that the second actual illumination intensity E2 is inconsistent with the preset illumination intensity E0, the adjusted light source illumination power can be adjusted again by a power value of ±0.036p0. That is, if the second actual illumination intensity E2 is not less than the preset illumination intensity E0, the power value is reduced by 0.036p0 on the basis of the adjusted output power; if the second actual illumination intensity E2 is less than the preset illumination intensity E0, the power value is increased by 0.036p0 on the basis of the adjusted output power.

[0092] Through the above steps S131-S144, the illumination adjustment method proposed by the present invention compares the difference between the actual illumination intensity and the preset illumination intensity, and only when the difference exceeds the preset threshold value, the power is adjusted according to the comparison result. In addition, after the power adjustment, the difference between the adjusted actual illumination intensity and the preset illumination intensity is checked again, and then a second adjustment is performed. In this way, the actual illumination intensity is made as close as possible to the preset light illumination, and the power adjustment accuracy of the lighting device 1 is improved.

[0093] Furthermore, based on the above-mentioned Embodiment 1 and Embodiment 2 of the illumination adjustment method described in the present invention, Embodiment 3 of the illumination adjustment method described in the present invention is proposed.

[0094] like Figure 5 FIG. 1 is a flow chart of Embodiment 3 of the illumination adjustment method of the present invention. Figure 5 The execution order of the steps in the flowchart shown may be changed, and some steps may be omitted.

[0095] In this embodiment, after step S144, the illumination adjustment method further includes:

[0096] Step S145 , detecting a third actual illumination intensity E3 at the preset position.

[0097] Step S146, calculating the difference between the preset light intensity E0 and the second actual light intensity E3, and determining whether the difference exceeds the preset threshold. If so, executing step S147; if not, ending the process.

[0098] Step S147, the adjusted light source illumination power is adjusted again to a power value of ±0.036p0.

[0099] It should be noted that the above-mentioned third adjustment is only an example. In this embodiment, if the preset light intensity E0 is still inconsistent with the actual light intensity value after this adjustment, the "detection-judgment-adjustment" cycle such as step S145-step S147 can be started again as needed until the preset light intensity E0 is consistent with the actual light intensity value.

[0100] Through the above steps S145-S147, the illumination adjustment method proposed in the present invention compares the actual light intensity after the second power adjustment with the preset light intensity. When the actual light intensity is still inconsistent with the preset light intensity, the power value is fine-tuned again to ensure that the actual light intensity gradually approaches the preset light intensity, thereby further improving the accuracy of the automatic adjustment of the lighting device 1.

[0101] Secondly, the present invention also provides a lighting device 1.

[0102] In this embodiment, the lighting device 1 includes the memory 11, the processor 12, and computer program instructions stored in the memory and executable by the processor. When the computer program instructions are executed by the processor 12, the following steps can be implemented:

[0103] Step S110, querying a preset light intensity E0 of a light source at a preset position.

[0104] In this embodiment, the lighting device 1 is used in the user's home, such as a living room, bedroom, study, etc. The device can be a smart lamp such as a desk lamp, ceiling lamp, chandelier, etc., which is mainly used to provide lighting services for users to meet their learning and living needs. The preset position refers to a position frequently used by the user near the lighting device 1, such as a desk in a study, a dressing table in a bedroom, a dining table and a coffee table in a living room, a sofa and a coffee table in an entertainment room, etc.

[0105] Generally, the light sources of the lighting devices 1 at different positions are preset with different preset light intensities E0. Specifically, the lighting modes of the lighting device 1 can be classified and set in advance, and the lighting modes may include, but are not limited to, reading mode, rest mode, dining mode, and entertainment mode. Among them, different lighting modes are preset with different brightness and / or light intensity, and the brightness and / or light intensity are used to meet the user's lighting needs for reading, resting, dining and entertainment respectively. For example, usually, the optimal light intensity for users to read is 600cd (cd: candela), the optimal light intensity for users to rest is 400cd, the optimal light intensity for users to dine is 800cd, and the optimal light intensity for users to entertain is 1000cd. Therefore, in this embodiment, when the lighting mode is a reading mode, the preset light intensity E0 of the lighting device 1 can be set to 600 cd (cd: candela); when the lighting mode is a rest mode, the preset light intensity E0 can be set to 400 cd; when the lighting mode is a dining mode, the preset light intensity E0 can be set to 800 cd; when the lighting mode is an entertainment mode, the preset light intensity E0 can be set to 1000 cd.

[0106] In this embodiment, the lighting device 1 can query the preset light intensity E0 of the light source of the lighting device 1 in real time or at a fixed time. In another embodiment, before querying the preset light intensity E0 of the light source, the lighting device 1 can also query the current lighting mode of the lighting device 1, and the current lighting mode at least includes reading mode, rest mode, dining mode, and entertainment mode; and then query the preset light intensity E0 in the corresponding lighting mode. In addition, in another embodiment, the lighting device 1 can also be connected to a camera, and the above-mentioned steps of querying the current lighting mode of the lighting device 1 and the preset light intensity E0 in the corresponding lighting mode are performed when and only when the camera captures the user image at the preset position.

[0107] Step S120: detecting a first actual light intensity E1 at a preset position.

[0108] As described above, the preset position is a position frequently used by users near the lighting device 1. In this embodiment, at least one light intensity detector, such as a light intensity detector, a light intensity tester, a light illuminance meter, etc., may be arranged at the preset position to detect the actual light intensity at the preset position. The actual light intensity may include the first actual light intensity E1.

[0109] Step S130: comparing the preset light intensity E0 with the first actual light intensity E1.

[0110] In this embodiment, after obtaining the first actual illumination intensity E1 of the preset position, the first actual illumination intensity E1 can be compared with the preset illumination intensity E0 to determine whether the actual illumination intensity of the preset position meets the preset optimal illumination intensity. For example, if the illumination mode of the illumination device 1 is the reading mode, the preset illumination intensity E0 of the illumination device 1 queried above is generally 600cd. At this time, if the first actual illumination intensity E1 detected is 300cd, the embodiment can compare 600cd with 300cd to determine whether the actual illumination intensity of the preset position is consistent with the expected situation. That is, compare whether there is a large difference between the preset illumination intensity E0 and the first actual illumination intensity E1, and whether the two are inconsistent.

[0111] Step S140, calculating a power adjustment value P according to the comparison result, a height h between the light source and the preset position plane, and an angle β between the light source direction and the vertical direction.

[0112] like Figure 3As shown, it is a schematic diagram of the light source illumination provided in this embodiment. It can be seen from the figure that the plane perpendicular to the illumination direction of the light source of the lighting device 1 is N, and the preset position plane where the user is located is H, the preset light intensity of the preset position is E0, the first actual light intensity is E1, the height of the light source of the lighting device 1 and the preset position plane H is h, the default illumination power of the light source is p0, the luminous efficiency parameter is k, and the angle between the light source direction and the vertical direction is β.

[0113] When the preset light intensity E0 and the first actual light intensity E1 are significantly different and inconsistent, it is necessary to adjust the light source output power of the lighting device 1 to reduce or increase the light intensity at the preset position. In this embodiment, the calculation formula of the power adjustment value P is:

[0114]

[0115] Where E0 is the preset light intensity, E1 is the first actual light intensity, h is the height between the light source and the preset position plane, p0 is the default irradiation power of the light source, k is the luminous efficiency parameter of the light source, and θ is the complementary angle of the angle β between the light source direction and the vertical direction.

[0116] Step S150: adjusting the power value according to the power The lighting power of the light source is adjusted so that the first actual illumination intensity E1 at the preset position is consistent with the preset illumination intensity E0.

[0117] As described above, when the power adjustment value is calculated When the lighting device 1 controls the output power of the light source to adjust, based on the original output power, reduce or increase The output power of the power value, that is, adjust the original output power up or down In other words, if the first actual illumination intensity E1 is less than the preset illumination intensity E0, then the original output power of the lighting device 1 is increased by If the first actual illumination intensity E1 is not less than the preset illumination intensity E0, then the original output power of the lighting device 1 is reduced by In this way, the first actual illumination intensity E1 at the preset position is as consistent as possible with the preset illumination intensity E0.

[0118] Through the above steps S110-S150, the lighting device 1 proposed in the present invention detects the actual light intensity at a preset position, and compares the actual light intensity with the preset optimal light intensity, and then calculates the output power adjustment value of the lighting device that needs to be adjusted through a preset light intensity power conversion formula, thereby realizing automatic adjustment of the output power of the lighting device, and improving the intelligence level of the lighting device and user experience.

[0119] Furthermore, based on the above-mentioned embodiment 1 of the lighting device 1 of the present invention, embodiment 2 of the lighting device 1 of the present invention is proposed.

[0120] In this embodiment, the computer program instructions are executed by the processor 12. When implementing step S130, the following steps may be implemented:

[0121] Step S131, calculate the difference between the preset light intensity E0 and the first actual light intensity E1, and determine whether the difference exceeds a preset threshold. If yes, execute step S140; if no, end the process.

[0122] In this embodiment, the standard for judging whether the actual light intensity is consistent with the preset light intensity is: whether the difference between the preset light intensity E0 and the first actual light intensity E1 exceeds a preset threshold. The preset threshold refers to a preset floating range value, that is, the actual light intensity can be higher or lower than the preset light intensity, as long as it does not exceed the range, the light intensity of the two is consistent. Furthermore, when the lighting mode of the lighting device 1 is different, the preset threshold value may also be a different floating range value, for example: when the lighting mode of the lighting device 1 is a reading mode, the preset threshold value is ±70cd, that is, E0∈[E0-70cd, E0+70cd]; when the lighting mode is a rest mode, the preset threshold value is ±50cd, that is, E0∈[E0-50cd, E0+50cd]; when the lighting mode is a dining mode, the preset threshold value is ±90cd, that is, E0∈[E0-90cd, E0+90cd]; when the lighting mode is an entertainment mode, the preset threshold value is ±110cd, that is, E0∈[E0-110cd, E0+110cd].

[0123] The step S140 specifically includes:

[0124] Step S141: adjusting the power value according to the Adjust the lighting power of the light source The power value.

[0125] In this embodiment, when the power adjustment value P is calculated, the lighting device 1 controls the output power of the light source to adjust, and reduces or increases the output power of the P power value on the basis of the original output power, that is, adjusts the ±P power value above and below the original output power. In other words, if the first actual light intensity E1 is less than the preset light intensity E0, the P power value is increased on the basis of the original output power of the lighting device 1. If the first actual light intensity E1 is not less than the preset light intensity E0, the P power value is reduced on the basis of the original output power of the lighting device 1.

[0126] Step S142, detecting a second actual illumination intensity E2 at the preset position.

[0127] As described above, after adjusting the output power of the lighting device 1, this embodiment also needs to re-detect the actual light intensity value of the preset position, that is, detect the second actual light intensity E2 of the preset position to verify whether the actual light intensity value of the preset position is consistent with the preset light intensity value E0.

[0128] Step S143, calculating the difference between the preset light intensity E0 and the second actual light intensity E2, and determining whether the difference exceeds a preset threshold; if so, executing step S144; if not, ending the process.

[0129] In this embodiment, the preset threshold is mainly used to measure whether the preset light intensity E0 and the second actual light intensity E2 are consistent. Therefore, the preset threshold can be consistent with the preset threshold in step S131, that is, when the lighting mode of the lighting device 1 is different, the preset threshold can also be a different floating range value. For example: when the lighting mode of the lighting device 1 is a reading mode, the preset threshold is ±70cd, that is, E0∈[E0-70cd, E0+70cd]; when the lighting mode is a rest mode, the preset threshold is ±50cd, that is, E0∈[E0-50cd, E0+50cd]; when the lighting mode is a dining mode, the preset threshold is ±90cd, that is, E0∈[E0-90cd, E0+90cd]; when the lighting mode is an entertainment mode, the preset threshold is ±110cd, that is, E0∈[E0-110cd, E0+110cd].

[0130] Step S144, the adjusted light source illumination power is adjusted again to a power value of ±0.036p0.

[0131] In this embodiment, when the second actual light intensity E2 is inconsistent with the preset light intensity E0, it means that the first adjustment is not in place. However, since a relatively large power adjustment has been made once, it is not appropriate to make a large power adjustment again. In addition, it is found through research that after the first large power adjustment, only a small power adjustment is needed to make the actual light intensity provided by the adjusted lighting device 1 close to or even consistent with the preset light intensity E0.

[0132] Therefore, in this embodiment, when it is found that the second actual illumination intensity E2 is inconsistent with the preset illumination intensity E0, the adjusted light source illumination power can be adjusted again by a power value of ±0.036p0. That is, if the second actual illumination intensity E2 is not less than the preset illumination intensity E0, the power value is reduced by 0.036p0 on the basis of the adjusted output power; if the second actual illumination intensity E2 is less than the preset illumination intensity E0, the power value is increased by 0.036p0 on the basis of the adjusted output power.

[0133] Through the above steps S131-S144, the lighting device 1 proposed by the present invention compares the difference between the actual light intensity and the preset light intensity, and only when the difference exceeds the preset threshold value, the power is adjusted according to the comparison result. In addition, after the power adjustment, the difference between the adjusted actual light intensity and the preset light intensity is checked again, and then a second adjustment is performed. In this way, the actual light intensity is made as close as possible to the preset light intensity, and the power adjustment accuracy of the lighting device 1 is improved.

[0134] Furthermore, based on the above-mentioned Embodiment 1 and Embodiment 2 of the lighting device 1 of the present invention, Embodiment 3 of the lighting device 1 of the present invention is proposed.

[0135] In this embodiment, when the computer program instructions are executed by the processor 12, after implementing step S144, the following steps may also be implemented:

[0136] Step S145 , detecting a third actual illumination intensity E3 at the preset position.

[0137] Step S146, calculating the difference between the preset light intensity E0 and the second actual light intensity E3, and determining whether the difference exceeds the preset threshold. If so, executing step S147; if not, ending the process.

[0138] Step S147, the adjusted light source illumination power is adjusted again to a power value of ±0.036p-0.

[0139] It should be noted that the above-mentioned third adjustment is only an example. In this embodiment, if the preset light intensity E0 is still inconsistent with the actual light intensity value after this adjustment, the "detection-judgment-adjustment" cycle such as step S145-step S147 can be started again as needed until the preset light intensity E0 is consistent with the actual light intensity value.

[0140] Through the above steps S145-S147, the lighting device 1 proposed in the present invention compares the actual light intensity after the second power adjustment with the preset light intensity. When the actual light intensity is still inconsistent with the preset light intensity, the power value is fine-tuned again to ensure that the actual light intensity gradually approaches the preset light intensity, thereby further improving the accuracy of the automatic adjustment of the lighting device 1.

[0141] Finally, the present invention also provides a computer-readable storage medium.
