Other features and functions of the present invention will be clearly presented in the embodiment with reference to the drawings, in which: FIG. 1 is a hardware connection diagram of an embodiment of the light amount monitoring method of the present invention; and FIG. 2 is the A flowchart of an embodiment.

Referring to FIG. 1, an embodiment of the light quantity monitoring method of the present invention is implemented by a light quantity monitoring system. The light quantity monitoring system includes a light quantity sensing unit 1, a storage unit 2, a prompt unit 3, and a processing unit 4 electrically connected to the light quantity sensing unit 1, the storage unit 2, and the prompt unit 3. The light quantity sensing unit 1 can generate sensing data indicating the light quantity. In this embodiment, the light quantity sensing unit 1 generates hourly The sensing data is once, but not limited to this. In other implementations, the light amount sensing unit 1 generates the sensing data once every second.

The following describes the process steps of this embodiment in conjunction with the flowchart shown in FIG. 2. First, as shown in step S01, the processing unit 4 determines whether the sensing data generated by the light amount sensing unit 1 is received. If so, step S02 is executed and then step S03 is executed. If not, step S03 is directly executed.

Step S02 is the processing unit 4 storing the sensing data to the storage unit 2.

Step S03 is the processing unit 4 judging whether the current time reaches one of a plurality of predetermined time points, if yes, step S04 is executed, if not, step S01 is executed again. In this embodiment, the predetermined time points are 12 o'clock noon and 6 o'clock in the evening, respectively (this time point may be the sunset time obtained by the server of the Central Meteorological Bureau of the processing unit 4), but not as However, the predetermined time point may also be twelve noon, six o'clock in the evening, and ten o'clock in the evening (the sleep time entered by the user).

Step S04 is that the processing unit 4 calculates a cumulative light amount. The accumulated light intensity is the sum of the light intensity indicated by the stored sensing data within a time range corresponding to one of the predetermined time points. In this embodiment, if the predetermined time point that the current time arrives is twelve noon, the time range corresponding to the predetermined time point is six o'clock in the morning (this time point may be the time for the user to enter the wake-up time) to the current day Six hours at twelve noon; if the scheduled time that the current time arrives is six o'clock in the evening, then The time range that should be scheduled is from twelve hours in the morning to six in the evening. That is, if the current time reaches twelve noon, the cumulative light amount calculated by the processing unit 4 is the sum of the light amount indicated by the stored sensing data between six o'clock in the morning and twelve noon in the day; If the current time reaches six o'clock in the evening, the cumulative light amount calculated by the processing unit 4 is the sum of the light amount indicated by the stored sensing data between six o'clock in the morning and six o'clock in the evening.

Next, as shown in step S05, the processing unit 4 determines whether the accumulated light amount calculated in step S04 falls within a predetermined light amount range. If not, step S06 is executed, and if so, step S01 is executed again. In this embodiment, the predetermined light intensity range can be customized by user input, and the predetermined light intensity range represents a range of appropriate light intensity. If the accumulated light intensity is higher than the predetermined light intensity range, it represents the user The amount of received light is too much. If the accumulated light amount is lower than the predetermined light amount range, it means that the user receives insufficient light amount.

Step S06 is that the processing unit 4 outputs a prompt output indicating that the accumulated light amount does not fall within the predetermined light amount range through the prompt unit 3, for the user to adjust the light amount received by the remaining time of the day through the prompt output. For example, when the user knows that the amount of light received in the morning is insufficient through the prompt output, the user can go out to illuminate the outdoor in the afternoon, or light up the lamps in the environment to supplement their daily light. The way of outputting the prompt output may be that the light emitting module emits light, the speaker module emits a warning sound, the vibration module generates vibration or the display module displays a prompt message.

It is added that in this embodiment, the processing unit 4 is composed of a first processing module of a wearable light amount sensing device (such as an electronic bracelet) and a portable electronic device (such as a smart phone) A second processing module; the storage unit 2 is composed of a first storage module of the wearable light amount sensing device and a second storage module of a portable electronic device. The wearable light quantity sensing device further includes a light quantity sensing unit 1 and a first communication module (such as a Bluetooth communication module), and the portable electronic device includes a prompt unit 3 and a second communication module (such as blue Bud Communication Module). The first processing module can control the first storage module to store the sensing data, and can also transmit the sensing data to the portable electronic device via the first communication module for the second processing module to communicate via the second The module receives and stores to the second storage module. The second processing module executes to determine whether the current time reaches a predetermined time point, calculate the accumulated light amount, determine whether the accumulated light amount falls within the predetermined light amount range, and control the prompt unit 3 to output the prompt output. The hardware structure for implementing the present invention is not limited to the foregoing, but can also be implemented by the wearable light amount sensing device alone. In addition, the implementation of the wearable light intensity sensing device is not limited to the electronic bracelet. The wearable light intensity sensing device can also be integrated on pins, brooches, buttons, necklace pendants, tags or glasses.

Furthermore, in another embodiment, the light quantity sensing unit 1 includes a blue light filter, so that the light quantity sensing unit 1 can sense light with a wavelength between 420 and 480 nm, but the present invention does not The blue light filter is limited, and the light amount sensing unit 1 may also include a filter for filtering light of other wavelength bands. this In addition, the processing unit 4 can display multiple pieces of sensing data stored in the storage unit 2 through the display module, so that the user can know the long-term light intensity.

In summary, in the embodiment of the light quantity monitoring method of the present invention, the processing unit 4 periodically determines whether the accumulated light quantity falls within the predetermined light quantity range, and outputs the prompt output through the prompt unit 3, which can effectively help the user Monitoring the amount of light received by itself, which in turn contributes to the implementation of light therapy, can indeed achieve the purpose of the invention.
