Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blue light irradiation equipment, in particular to a timing device for blue light irradiation equipment and the blue light irradiation equipment. Background Art
[0002] At present, the simpler and more effective method for treating jaundice in infants and young children is "light therapy", which uses blue light to irradiate the child's skin, so that the bilirubin in the patient's body is converted into other substances in a short period of time, so that the accumulated bilirubin in the body can be quickly excreted, and the symptoms of jaundice can gradually improve and eventually disappear completely.
[0003] The light sources used in the blue light medical devices for jaundice that are usually used for "light therapy" are all LED light sources. However, as the use time of LED light sources increases, light decay will occur. When the light decay of the LED light source reaches a certain level, the blue light effect it emits will weaken, which will also reduce the effect of treating jaundice. In order to ensure the treatment effect of jaundice, it is necessary to record the working time of the LED light source. When the working time of the LED light source reaches a certain time, it is necessary to test the blue light effect of the LED light source. If the blue light effect of the LED light source has weakened, the LED light source needs to be replaced. In order to accurately record the working time of the LED light source, it is necessary to add a timing function to the blue light medical device for jaundice.
[0004] In the prior art, timing circuits or timing chips are generally used to count time. When the LED light source is powered on, timing starts, and when the LED light source is not powered on, timing ends automatically. Although this method can count the duration of normal operation of the LED light source, when an abnormality occurs in the LED light source, such as some LED particles in the LED light source are short-circuited or open-circuited, or the LED light source is not connected to the system due to some circumstances, at this time, the part of the LED light source has stopped working due to abnormal protection or there is no LED light source, but the power supply of the LED light source still exists, so the timing function will continue to count. This technical method will cause an error between the actual working time of the LED light source and the time counted by the timing circuit, and it is impossible to accurately count the working time of the LED light source.

[0027] The terms "including" and "having" and any variations thereof in the specification and claims of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.
[0028] An embodiment of the utility model provides a timing device for a blue light irradiation device, which is used for timing the working duration of a light source of the blue light irradiation device, and includes a detection unit and a processing unit. The detection unit is used to obtain load information of the light source of the blue light irradiation device, and the processing unit is used to determine the current working state of the light source of the blue light irradiation device according to the load information, and further determine whether to perform a timing operation.
[0029] The following is a detailed description of the various structures of the timing device of the blue light irradiation device provided in the embodiment of the utility model, as well as the positional relationship and connection relationship between the various structures, in conjunction with the accompanying drawings.
[0030] like Figure 1 and Figure 2As shown, the detection unit is configured to obtain the load data information of the light source and transmit the load data information to the processing unit; for example, the load information of the light source is the load voltage information of the light source, wherein the light source includes a plurality of LED lamps connected in series and / or in parallel, and when all the LED lamps operate normally, it is a set load voltage range, that is, the rated load voltage. However, when some of the LED lamps are short-circuited, the voltage of the entire light source will decrease, that is, the actual load voltage supplied to the load will decrease; when the LED lamp is open-circuited or the light source is not connected to the system, the actual load voltage supplied to the load will increase; therefore, it is only necessary to detect the actual load voltage supplied to the load and then compare it with the rated load voltage to determine whether the light source has abnormal conditions such as short-circuit, open-circuit or the light source is not connected to the system. The embodiment of the utility model is designed based on this principle.
[0031] In an embodiment of the utility model, the detection unit includes a detection circuit, which is used to obtain the load data information of the light source and transmit the load data information to the processing unit. For example, the detection circuit obtains the load data information of the light source according to a set period, such as obtaining it every 50 seconds or 100 seconds, or the load data information of the light source is obtained in real time through the detection circuit.
[0032] For example, the detection circuit includes a first resistance structure R1, a second resistance structure R2 and a capacitor structure C1; the first resistance structure R1 and the second resistance structure R2 are connected in series, the capacitor structure C1 and the second resistance structure R2 are connected in parallel, and one end of the first resistance structure R1 is connected to the positive electrode of the light source, and one end of the second resistance structure R2 is connected to the negative electrode of the light source. In this detection circuit, the actual load voltage of the light source is determined by calculating the load voltage of the second resistance structure R2.
[0033] The first resistance structure R1 , the second resistance structure R2 , and the capacitance structure C1 include one electronic component or multiple electronic components connected in series and / or in parallel.
[0034] Continue to refer Figure 1 and Figure 2 As shown in the figure, the first resistance structure R1, the second resistance structure R2 and the capacitor structure C1 form a detection circuit (load voltage acquisition circuit). Since the first resistance structure R1 and the second resistance structure R2 are resistors, the voltage V on the second resistance structure R2 R2 =V LED ×R R2 / (R R1 +R R2 ), where V LED is the load voltage for powering the light source, R R1 and R R2are the resistance values of the first resistance structure R1 and the second resistance structure R2, respectively, and their resistance values are fixed values. Thus, we can get: V LED =V R2 ×(R R1 +R R2 ) / R R2 Therefore, it can be known that the load voltage of the light source can be obtained by calculating only the voltage on the second resistance structure R2.
[0035] In an embodiment of the utility model, the processing unit includes a comparison module and a timing module. The comparison module is configured to receive the load data information and send a comparison result signal after comparing it with the set load data information. The timing module is configured to receive the comparison result signal and start or stop the timing. Among them, the comparison result includes two comparison results, the first one is that the load data information is within the set load data information range, and the second one is that the load data information is not within the set load data information range. When the comparison result received by the timing module is the first one, it means that the light source is operating normally, and the timing is started. On the contrary, when the comparison result received by the timing module is the second one, the timing is stopped or not started.
[0036] For example, the processing unit is a programmable control chip U1 with multiple pins. If the chip U1 is an 8-pin chip, the voltage on the second resistor structure R2 is sent to the 6th pin PA6 of the chip U1. There is an analog-to-digital conversion inside, and the chip U1 can collect V R2 , V is obtained through internal calculation LED Chip U1 uses the collected V LED The data is compared with the rated data (set load data information). If V LED If the data is within the normal working range, the timing is started and the working time of the light source is accumulated; if V LED If the data is not within the normal working range, the chip U1 will not count. It can be seen that this timing method determines the start and stop of timing by judging the operating conditions of the light source. Compared with the timing method of powering on, it can accurately count the actual working time of the light source.
[0037] In the embodiment of the utility model, the processing unit also includes a storage module; the storage module is configured to store set load data information, and the comparison module obtains the set load data information in the storage module and compares it with the received load data information. The set load data information can be set according to different light source devices, that is, different light source devices have different rated load voltages, and the set load data information can be updated in the storage module. And the storage module is also configured to store the timing information of the timing module, even if there are unexpected situations such as power failure, it will not cause data loss, and when it is operating normally again, it can continue to time according to the current data to further ensure the accuracy of the timing.
[0038] In an embodiment of the utility model, the storage module is also configured to store abnormal working time information; the abnormal working time information is the timing information of the light source whose load data information does not conform to the set load data information. For example, adding statistical data for storing abnormal working time will assist in the analysis, repair and detection of abnormal light sources, and provide help for subsequent product maintenance. When the acquired load data information does not conform to the set load data information, a recording operation is performed. At this time, the light source may be abnormal, and the record can be used as an auxiliary basis for abnormal detection.
[0039] In the embodiment of the utility model, the timing device also includes an alarm unit, which is configured to drive the start and stop of the alarm device according to the comparison result signal. That is, when there is an abnormality (the load data information does not conform to the set load data information), the alarm operation can be performed in time to achieve the purpose of reminder, or when the timing data information of the timing module reaches the set value, the alarm operation can be performed, that is, the working time of the light source reaches the upper limit and needs to be replaced.
[0040] The embodiment of the utility model also provides a blue light irradiation device, including the timing device of the blue light irradiation device. For example, the blue light irradiation device is a wearable device, and the wearable device is equipped with the timing device of the blue light irradiation device, and the working time of the blue light source is more accurately timed by using the technical device.
[0041] Compared with the prior art, the beneficial effects of the utility model are:
[0042] The timing device and blue light irradiation device provided by the embodiment of the utility model obtain the load data information of the light source through the detection unit, and compare the load data information with the normal load data. When the load data information obtained is within the normal load data range, it means that the light source is in a normal operating state, and the timing can be started, otherwise the timing will not be started. Compared with the existing power-on timing method, the technical solution of the utility model can monitor the operating time of the light source more accurately and avoid / reduce the waste of resources.
