Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to a fully intelligent desk lamp for long-term reading that protects the eyes. Background Technology

[0002] Prolonged use of desk lamps for studying at night is common among students. However, eye fatigue increases over time, especially during long reading sessions when the eyes are exposed to the same intensity of light for extended periods, leading to constant-power light fatigue.

[0003] Therefore, depending on the level of eye fatigue, the intensity of the desk lamp needs to be adjusted to alleviate eye strain and make the lamp more suitable for use when the eyes are in different states of fatigue. However, the light wattage of desk lamps is usually fixed, and teenagers rarely consciously adjust the intensity of their desk lamps. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this invention is to provide a fully intelligent long-term reading eye-protection desk lamp.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a fully intelligent long-term reading eye protection desk lamp, including a human body sensing device, a light sensing device, a timing device, a light intensity adjustment device, a color temperature adjustment device, and a control motherboard device;

[0006] The human body sensor is connected to the control motherboard via a signal, and the human body sensor is used to detect the presence of a human body.

[0007] The light sensor is connected to the control motherboard via a signal, and the light sensor is used to detect the intensity of light in the space outside the area illuminated by the eye-protection desk lamp.

[0008] The color temperature adjustment device is used to adjust the color temperature of the desk lamp, with an adjustment range of 3000-4000K to meet the light requirements in reading scenarios;

[0009] The control motherboard device is signal-connected to the timing device. When the eye-protection desk lamp is turned on, the control motherboard device receives the first detection signal of the presence of a human body sent by the human body sensor and controls the timing device to start timing. The timing device sends the measured sensing time to the control motherboard device in real time.

[0010] The light intensity adjustment device is signal-connected to the control motherboard device, and the control motherboard device determines the initial light intensity of the eye-protection desk lamp based on the ambient light intensity signal sent by the light sensor device.

[0011] When the received effective reading time is greater than or equal to the first standard time, the control motherboard device controls the light intensity adjustment device to operate the adjustment mode. The effective reading time refers to the actual reading time when a human uses the eye-protection desk lamp.

[0012] The adjustment mode includes: reducing the light intensity of the eye-protection desk lamp by 5-10% at each first set time interval; and increasing the light intensity of the eye-protection desk lamp by 5-10% at each second set time interval when the light intensity of the eye-protection desk lamp drops to 85% of the initial light intensity, until the initial light intensity is reached.

[0013] As a further improvement of the present invention: the control motherboard device receives the sensing time and determines the blank reading time when the human body leaves the eye-protection desk lamp; if the blank reading time is greater than or equal to the calibrated time, the timing device is controlled to start timing again; if the blank reading time is less than the calibrated time, the sensing time minus the blank reading time is the effective reading time; if there is no blank reading time, the sensing time is the effective reading time.

[0014] As a further improvement of the present invention: after the timing device starts timing, when the control motherboard device receives the second detection signal sent by the human body sensing device indicating that a human body has left, it sets the sensing time to a first mark. When the control motherboard receives the first detection signal again, it sets the sensing time to a second mark, and records the time period between the first mark and the second mark as a blank reading time. Wherein, the first mark refers to the time node of the eye-protection desk lamp when the human body leaves during the sensing time, and the second mark refers to the time node of the eye-protection desk lamp when the human body is present during the sensing time.

[0015] As a further improvement of the present invention: when the received effective reading time is greater than or equal to the second standard time, the control motherboard device controls the light intensity adjustment device to run the reminder mode to remind the user to close their eyes and rest.

[0016] As a further improvement of the present invention: the reminder mode includes: every third set time interval, controlling the eye-protection desk lamp to flash randomly at a frequency of 4-8HZ for a preset time.

[0017] As a further improvement of the present invention: the adjustment mode includes: reducing the light intensity of the eye-protection desk lamp by 5% every 10 minutes; when the light intensity of the eye-protection desk lamp is reduced to 85% of the initial light intensity, increasing the light intensity of the eye-protection desk lamp by 5% every 10 minutes until the initial light intensity is reached.

[0018] As a further improvement of the present invention: the light sensor is installed outside the illumination area of ​​the eye-protection desk lamp.

[0019] As a further improvement of the present invention: the control motherboard device selects the corresponding light intensity data from the preset optimal ambient light intensity information database according to the ambient light intensity signal sent by the light sensor, and uses it as the initial light intensity of the eye-protection desk lamp.

[0020] As a further improvement of the present invention: the human body sensing device includes an infrared sensor.

[0021] As a further improvement of the present invention: the light sensing device includes a photoelectric sensor.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention utilizes a human body sensor, a light sensor, a timing device, a light intensity adjustment device, and a control motherboard to intelligently and dynamically adjust the light intensity and color temperature of the eye-protecting desk lamp based on the effective reading time. Once the effective reading time reaches a first standard time, it enters an adjustment mode, gradually decreasing or increasing the light intensity at intervals to reduce light stimulation to the eyes, alleviate eye fatigue, and prevent eye strain caused by constant power light and color temperature during prolonged reading. This promotes healthy eye care. Attached Figure Description

[0024] Figure 1 This is a schematic diagram of the control flow of the present invention.

[0025] Figure 2 The graph shows the light intensity variation of the eye-protecting desk lamp in Example 1. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] In order to solve the technical problems in the prior art, the present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0028] like Figure 1As shown, the present invention discloses a fully intelligent long-term reading eye-protection desk lamp, including a human body sensing device, a light sensing device, a timing device, a light intensity adjustment device, a color temperature adjustment device, and a control motherboard device. The human body sensing device, the timing device, the light sensing device, the light intensity adjustment device, and the control motherboard device are each independently installed on or in the eye-protection desk lamp.

[0029] The human body sensor is connected to the control motherboard device via a signal. The human body sensor is used to detect the presence of a human body. If a human body is detected, the sensor converts a first detection signal into an electrical signal and sends it to the control motherboard device. If a human body is not detected, the sensor converts a second detection signal into an electrical signal and sends it to the control motherboard device.

[0030] The light sensor is connected to the control motherboard via a signal. The light sensor is used to detect the intensity of ambient light outside the illumination area of ​​the eye-protection desk lamp and sends the detected ambient light intensity signal to the control motherboard. Correspondingly, the light sensor is installed at a position outside the illumination area of ​​the eye-protection desk lamp.

[0031] For example, the light sensor is installed at the top of the eye-protection desk lamp. Under normal circumstances, since the eye-protection desk lamp shines downwards, the space above it is not illuminated by the lamp. In other words, the detection space of the light sensor is set opposite to the illumination area of ​​the eye-protection desk lamp.

[0032] The control motherboard is connected to the light intensity adjustment device, and the control motherboard determines the initial light intensity of the eye-protection desk lamp based on the ambient light intensity signal sent by the light sensor.

[0033] Optionally, the corresponding light intensity data is selected from the optimal ambient light intensity information database based on the ambient light intensity signal, and used as the initial light intensity of the eye-protection desk lamp. Before determining the initial light intensity of the eye-protection desk lamp, the optimal ambient light intensity information database is established in advance; wherein, the establishment of the optimal ambient light intensity information database is existing technology, and different ambient light intensity signals are at different light levels in the optimal ambient light intensity information database, and the corresponding light intensity data are also different.

[0034] The control motherboard is connected to the timing device. After the eye-protection desk lamp is turned on, when the control motherboard receives the first detection signal from the human body sensor, it controls the timing device to start timing. The timing device sends the measured sensing time to the control motherboard in real time.

[0035] Optionally, the control motherboard device receives the sensing time and determines the blank reading time when the human body leaves the eye-protection desk lamp; if the blank reading time is greater than or equal to the calibrated time, it controls the timing device to restart the timing; if the blank reading time is less than the calibrated time, the sensing time minus the blank reading time is the valid reading time; if there is no blank reading time, the sensing time is the valid reading time.

[0036] Optionally, after the timing device starts timing, when the control motherboard receives the second detection signal sent by the human body sensor indicating that a human body has left, it sets the sensing time to a first mark. When the control motherboard receives the first detection signal again, it sets the sensing time to a second mark, and records the time period between the first mark and the second mark as a blank reading time. Herein, the first mark refers to the time node of the eye-protection desk lamp when the human body leaves during the sensing time, and the second mark refers to the time node of the eye-protection desk lamp when the human body is present during the sensing time.

[0037] Prolonged exposure to the same light intensity can cause eye fatigue during extended reading. Regularly reducing or increasing the light intensity at intervals can reduce the light stimulation to the eyes, alleviate some eye fatigue, and improve brain concentration. Under prolonged constant light conditions, and in environments with varying light levels, it is less likely to cause eye fatigue and drowsiness.

[0038] Specifically, when the received effective reading time is greater than or equal to a first standard time, the control motherboard device controls the light intensity adjustment device to operate in adjustment mode; when the received effective reading time is greater than or equal to a second standard time, the control motherboard device controls the light intensity adjustment device to operate in reminder mode. Here, the effective reading time refers to the actual reading time spent by the user using the eye-protection desk lamp.

[0039] Specifically, the adjustment mode includes: reducing the light intensity of the eye-protection desk lamp by 5-10% at a first set time interval; when the light intensity of the eye-protection desk lamp drops to 85% of the initial light intensity, increasing the light intensity of the eye-protection desk lamp by 5-10% at a second set time interval until the initial light intensity is reached; the color temperature adjustment device adjusts the color temperature of the eye-protection desk lamp in a positive correlation with the light intensity of the eye-protection desk lamp, that is, the color temperature of the eye-protection desk lamp is adjusted synchronously with the light intensity, and the color temperature increases as the light intensity increases. For example, in the adjustment mode, the color temperature increases from 4000K to 3600K to 3300K to 3000K and then gradually increases to 4000K.

[0040] Specifically, the reminder mode includes: every third set time interval, controlling the eye-protection desk lamp to flash randomly at a frequency of 4-8 Hz for a preset time to remind the user to close their eyes and rest.

[0041] When the control motherboard device detects that the reminder mode has ended, it controls the eye-protection desk lamp to return to its initial state, that is, the light sensor re-senses the light intensity and matches the initial light intensity, the human body sensor re-detects the presence of a human body, and the timing device restarts the timing according to the instruction of the control motherboard device.

[0042] Example 1:

[0043] like Figure 1-2 As shown, this embodiment proposes a fully intelligent long-term reading eye-protection desk lamp, including a human body sensing device, a light sensing device, a timing device, a light intensity adjustment device, and a control motherboard device;

[0044] The human body sensor is connected to the control motherboard via a signal, and the human body sensor is used to detect the presence of a human body.

[0045] The light sensor is connected to the control motherboard via a signal, and the light sensor is used to detect the intensity of light in the space outside the area illuminated by the eye-protection desk lamp.

[0046] The control motherboard device is signal-connected to the timing device. When the eye-protection desk lamp is turned on, the control motherboard device receives the first detection signal of the presence of a human body sent by the human body sensor and controls the timing device to start timing. The timing device sends the measured sensing time to the control motherboard device in real time.

[0047] The light intensity adjustment device is signal-connected to the control motherboard device, and the control motherboard device determines the initial light intensity of the eye-protection desk lamp based on the ambient light intensity signal sent by the light sensor device.

[0048] When the received effective reading time is greater than or equal to the first standard time, the control motherboard device controls the light intensity adjustment device to operate the adjustment mode. The effective reading time refers to the actual reading time when a human uses the eye-protection desk lamp.

[0049] The adjustment mode includes: reducing the light intensity of the eye-protection desk lamp by 5-10% at each first set time interval; when the light intensity of the eye-protection desk lamp is reduced to 85% of the initial light intensity, increasing the light intensity of the eye-protection desk lamp by 5-10% at each second set time interval until the initial light intensity is reached.

[0050] Optionally, the color temperature adjustment device is used to adjust the color temperature of the desk lamp, with an adjustment range of 3000-4000K to meet the light requirements in reading scenarios and create a comfortable reading environment. When reading, the light at a color temperature of around 3000-4000K is soft and improves eye comfort. In conjunction with the light intensity adjustment device, the lamp's illumination intensity and color temperature are intelligently and dynamically adjusted to avoid light fatigue caused by constant power and color temperature, thus protecting the eyes.

[0051] Of course, the color temperature adjustment device has an adjustment range of 2700-6000K to meet the light requirements of different lighting scenarios.

[0052] The color temperature adjustment device adjusts the color temperature of the eye-protection desk lamp in a positively correlated manner with the light intensity of the eye-protection desk lamp. That is, the color temperature of the eye-protection desk lamp is adjusted synchronously with the light intensity. When the light intensity increases, the corresponding color temperature also increases. For example, in the adjustment mode, the color temperature increases from 4000K to 3600K to 3300K to 3000K and then gradually rises to 4000K.

[0053] The light sensor is installed outside the illumination area of ​​the eye-protection desk lamp, such as on the top of the lamp. The control board selects the corresponding light intensity data from a preset optimal ambient light intensity database based on the ambient light intensity signal sent by the light sensor, and uses this data as the initial light intensity of the eye-protection desk lamp.

[0054] Preferably, the human body sensing device includes an infrared sensor, and the light sensing device includes a photoelectric sensor.

[0055] Preferably, the control motherboard device receives the sensing time and determines the blank reading time when the human body leaves the eye-protection desk lamp; if the blank reading time is greater than or equal to the calibrated time, it controls the timing device to restart the timing; if the blank reading time is less than the calibrated time, the sensing time minus the blank reading time is the valid reading time; if there is no blank reading time, the sensing time is the valid reading time.

[0056] This embodiment considers the situation where a person leaves the eye-protection desk lamp, but the lamp remains in normal operation and the timing device continues to keep track of the reading time. It is necessary to determine the actual continuous reading time. Therefore, this embodiment calculates whether the time between the person leaving the lamp and the first detection signal from the human body sensor indicates that the person has not been using the lamp for continuous reading. If the time exceeds the calibrated time, it indicates that the person has not been using the lamp for continuous reading. The timing device is then restarted until the effective reading time reaches the first standard time, at which point the eye-protection desk lamp is put into adjustment mode.

[0057] More preferably, after the timing device starts timing, when the control motherboard device receives the second detection signal sent by the human body sensor indicating that a human body has left, it sets the sensing time to a first mark. When the control motherboard receives the first detection signal again, it sets the sensing time to a second mark, and records the time period between the first mark and the second mark as a blank reading time. Herein, the first mark refers to the time node of the eye-protection desk lamp when the human body leaves during the sensing time, and the second mark refers to the time node of the eye-protection desk lamp when the human body is present during the sensing time.

[0058] More preferably, such as Figure 2 As shown, the adjustment mode includes: reducing the light intensity of the eye-protection desk lamp by 5% every 10 minutes; when the light intensity of the eye-protection desk lamp drops to 85% of the initial light intensity, increasing the light intensity of the eye-protection desk lamp by 5% every 10 minutes until the initial light intensity is reached.

[0059] More preferably, when the received effective reading time is greater than or equal to the second standard time, the control motherboard device controls the light intensity adjustment device to operate in a reminder mode to remind the user to close their eyes and rest. The reminder mode includes: controlling the eye-protection desk lamp to flash randomly at a frequency of 4-8 Hz for a preset time every third set time interval.

[0060] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
