Description

Technical Field

[0001] This utility model relates to a recording device, and more particularly to a light recording device that can display the activity time by utilizing light. Background Technology

[0002] A one-year follow-up study was conducted on over 1,000 elementary school students aged 7 to 8 in northern, central, southern, and eastern Taiwan to explore the relationship between outdoor activities after school and the onset and progression of myopia. The results showed that children already suffering from myopia could reduce their myopia by an average of approximately 12 degrees per year by increasing outdoor activities, effectively slowing the progression of myopia. This finding has gained international attention, confirming that outdoor activities and sun exposure are effective methods for preventing myopia and slowing its progression.

[0003] Furthermore, studies show that repeated low-intensity red light irradiation can significantly slow the progression of myopia and even regress it. Compared to children wearing regular glasses, children receiving red light therapy experience a 70% reduction in axial elongation, and the treatment has the potential to reverse axial elongation. Multiple clinical studies have also confirmed that after one month of red light therapy, children experiencing axial shortening can reach up to 40%, an effect unattainable by other myopia treatments. The younger the child and the higher the degree of myopia, the better the treatment outcome. Red light therapy is suitable for most children with myopia, both mild and severe, and has passed the light safety test of the American National Standards Institute (ANSI), ensuring its safety and reliability. As long as the instrument is used correctly, there is virtually no risk to the eyes, and the effect is even more significant when combined with other treatments.

[0004] Sunlight exposure promotes vitamin D synthesis, which plays an important role in bone health, the immune system, and cardiovascular health. However, sun exposure time should be limited to 15 to 30 minutes per day to avoid sunburn and the risk of skin cancer. Health experts recommend spreading out sun exposure and avoiding prolonged outdoor activities during periods of strong sunlight, especially for children, the elderly, and those with sensitive skin, who should carefully control their sun exposure time and take sun protection measures.

[0005] In summary, reasonable and moderate sun exposure is beneficial for inhibiting myopia and improving human health. However, it is important to control the duration of exposure to avoid adverse effects from excessive exposure. Currently, technologies such as those disclosed in Taiwan Patent No. M 511655 exist that can record exposure time, but because they require microcontroller unit (MCU) control, they suffer from power consumption and structural complexity, issues that remain to be resolved.

[0039] See Figures 1 to 3 This is a first embodiment of the light recording device 1 of the present invention. The light recording device 1 includes: a housing unit 5, a photovoltaic unit 2, an adjustment unit 3, and a timing unit 4.

[0040] The housing unit 5 has a bottom shell 51, a light-transmitting cover 52 covering the bottom shell 51, and an internal space 53 defined by the bottom shell 51 and the light-transmitting cover 52. In this embodiment, the light-transmitting cover 52 is transparent and colorless, allowing most light to pass through. The housing unit 5 also has a wearing member 54 extending outward from the bottom shell for wearing on the wrist.

[0041] The photovoltaic unit 2 is installed inside the housing unit 5. In this embodiment, it is a solar cell used to receive sunlight and generate electricity. The photovoltaic unit 2 should preferably start working when the illuminance is greater than or equal to 1500 lux. The type is not limited to monocrystalline silicon. Other forms such as polycrystalline silicon, amorphous silicon cells, or organic cells are also acceptable, but are not the focus of this utility model.

[0042] The adjustment unit 3 is installed in the internal space 53 of the housing and is electrically connected to the photovoltaic unit 2. The connection method can be through wires or integrated onto a circuit board. It includes a first resistor 31, a second resistor 32 and a capacitor 33. The first resistor 31 is connected in series with the photovoltaic unit 2, and the second resistor 32 is connected in parallel with the capacitor 33 and coupled to the first resistor 31 after being connected in parallel. The adjustment unit 3 is used to output a drive signal containing voltage or current value information from the electrical energy generated by the photovoltaic unit 2.

[0043] The timing unit 4 is installed in the housing space 53 and electrically connected to the adjustment unit 3. In fact, it is connected in parallel with the second resistor 32 and capacitor 33 of the aforementioned adjustment unit 3. The timing unit 4 has a motor 41, an index component 42 driven by the motor 41, a frequency divider 44 electrically connected to the motor 41, and a quartz oscillator 43 electrically connected to the frequency divider 44.

[0044] The quartz oscillator 43 receives the drive signal sent from the aforementioned adjustment unit 3 and generates a suitable oscillation frequency through oscillation adjustment. The frequency divider 44 then adjusts the aforementioned oscillation frequency to match the operating conditions of the motor 41. When the motor 41 is driven by the drive signal, it can drive the indicator 42 to display a start time signal. Subsequently, when the motor 41 does not receive a drive signal, the indicator 42 can display an end time signal.

[0045] When a user is in a light-exposed environment, the photovoltaic unit 2 starts to generate electricity. As the voltage increases, it drives the current to flow through the first resistor 31 of the adjustment unit 3 and continues to accumulate charge in the capacitor 33 until the voltage value of the capacitor 33 meets the conditions for the quartz oscillator 43 to start oscillating. Then, the quartz oscillator 43 starts to output a signal to the frequency divider 44. After the quartz oscillator 43 and the frequency divider 44 work together to output a suitable waveform and frequency of the drive signal, the motor 41 will drive the indicator 42 to rotate to obtain a start time signal containing the start time, and the motor will continue to rotate. Conversely, when the user leaves the light-exposed environment, the photovoltaic unit 2 cannot work to provide electricity, or even if it provides electricity, the voltage or current value is lower than the voltage required by the quartz oscillator 43 or a working threshold of the motor 41, causing the quartz oscillator 43 to stop outputting a signal or the motor 41 to stop rotating. At this time, the end time signal is displayed. By comparing the difference between the start time signal and the end time signal, the approximate time the user was exposed to light can be known, which is convenient for recording.

[0046] The second embodiment of this utility model is largely the same as the first embodiment, except that the light-transmitting cover 52 of the second embodiment is designed to be red. This can be achieved by means of techniques such as film application or dyeing. In this way, only red light can pass through or non-red light, such as blue light, can be restricted. The time under specific lighting conditions can be recorded, further increasing the scope of application.

[0047] As can be seen from the above, the design of this utility model does not require the inclusion of microcontroller units (MCUs), batteries, or other components, thus reducing the overall number of parts and offering advantages such as energy saving, reduced manufacturing costs, and lighter equipment weight.

[0048] The above description is merely an embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the patent specification of this utility model shall still fall within the scope of this utility model patent.
