Detailed Description
In order to provide a further understanding and appreciation for the structural features and advantages achieved by the present invention, the following detailed description of the presently preferred embodiments is provided:
please refer to fig. 1, which is a diagram illustrating an ultraviolet LED package structure according to a first embodiment of the present invention. As shown, the uv LED package 1 of the present invention includes a substrate 10, a uv LED12, a driving device 14, a control device 16, an indicator light 18, and a package 19. The ultraviolet LED12 is disposed on one side of the substrate 10. The driving device 14 is disposed on the other side of the substrate 10, and is electrically connected to the ultraviolet LED12, and drives the ultraviolet LED12 to generate an illumination intensity 120 and an illumination time 122. The control device 16 is disposed on one side of the substrate 10 and the driving device 14, and includes a detecting module 160 and a processing module 162, wherein the detecting module 160 is electrically connected to the processing module 162, detects the illumination intensity 120 and the illumination time 122 to generate a detecting signal 1600, and the processing module 162 is electrically connected to the driving device 14, receives the detecting signal 1600, and controls the driving device 14 to adjust the illumination intensity 120. The indicator 18 is disposed on one side of the substrate 10 and the control device 16, electrically connected to the processing module 162, and receives the detection signal 1600 through the processing module 162 to change the brightness state of the indicator 18. The package 19 encapsulates the ultraviolet LED12, the driving device 14, the control device 16, and the indicator light 18 on the substrate 10.
To describe the embodiment of the uv LED package structure 1 of the present invention, first, the control device 16 operates the driving device 14, the driving device 14 inputs a current (including frequency) to the uv LED12, and the driving device 14 changes the magnitude and period of the output current to adjust the illumination intensity 120 of the uv LED12, so as to activate the uv LED12 to emit uv light for sterilization; the ultraviolet LED12 is a UVC ultraviolet light with a wavelength of 100nm to 280nm, and may be a single LED or a plurality of LEDs. The detecting module 160 is used as an ultraviolet Sensor (UV Sensor) for detecting the illumination intensity 120 and the illumination time 122 of the ultraviolet LED12 to generate a detecting signal 1600, and transmitting the detecting signal 1600 to the processing module 162, and the processing module 162 calculates and processes the detecting signal 1600 to determine whether the illumination intensity 120 of the ultraviolet LED12 reaches the energy intensity of a sterilization standard.
If the light intensity 120 of the uv LED12 is determined to reach the energy intensity of the sterilization standard, it indicates that the conversion efficiency of the driving device 14 to activate the uv LED12 is normal, and the light operation of the uv LED12 can be performed according to the preset operation time. Particularly, if it is determined that the illumination intensity 120 of the uv LED12 reaches the level above the sterilization standard, the processing module 162 may adjust the operation time 140 (as shown in fig. 2) and the output current intensity of the driving device 14 at a proper time to reduce the illumination time 122 of the uv LED 12. Therefore, the illumination time 122 of the ultraviolet LED12 is equal to the operation time 140 of the driving device 14, the driving device 14 is used as a switch component for turning on and off the ultraviolet LED12, and the sterilization mode of the ultraviolet LED12 is determined after the processing module 162 receives the detection signal 1600.
On the contrary, if the processing module 162 receives the detection signal 1600 and determines that the illumination intensity 120 of the uv LED12 does not reach the energy intensity of the sterilization standard, the processing module 162 increases the current input to the uv LED12 or increases the illumination time 122 by the adjustment driving device 14, so that the uv LED12 can reach the illumination intensity 120 of the standard sterilization operation.
Moreover, after the processing module 162 receives the detection signal 1600, it is equivalent to know the light energy intensity of the uv LED 12. Therefore, the processing module 162 can obtain the change of the illumination intensity 120 of the ultraviolet LED12 by the detection signal 1600, and further know the usage status of the ultraviolet LED12, so as to generate the brightness change in the indicator light 18, thereby prompting the user to pay attention to the current status of the ultraviolet LED 12. In detail, the brightness of the indicator light 18 changes correspondingly as the processing module 162 receives the detection signal 1600 for calculation and processing. The brightness of the indicator light 18 changes gradually, such as on, off, and flashing, to indicate whether the usage status of the ultraviolet LED12 is abnormal, so that the user can determine the operation status of the ultraviolet LED12 to avoid the effect of the sterilization process.
Please refer to fig. 2, which is a diagram illustrating an ultraviolet LED package structure according to a second embodiment of the present invention. As shown in the drawings, the difference between the first embodiment and the second embodiment of the ultraviolet LED package structure 1 of the present invention is that the detecting module 160 further includes a sensing module 164 electrically connected to the detecting module 160, and sensing the operating temperature of the driving device 14 and the ultraviolet LED12 to generate a sensing signal 1640, the sensing signal 1640 is transmitted to the detecting module 160, and the detecting signal 1600 includes the sensing signal 1640 received by the processing module 162 to adjust a working time 140 and an output current intensity of the driving device 14.
Since the driving device 14 and the uv LED12 generate heat after a period of operation, the generation of heat tends to reduce the performance of the driving device 14 and the power of the uv LED 12. Therefore, the sensing module 164 is used as a Temperature sensor (Temperature sensor) for sensing the operating Temperature of the driving device 14 and the ultraviolet LED12, and transmitting the sensing signal 1640 to the detecting module 160, and the detecting module 160 transmits the detecting signal 1600 with the sensing signal 1640 to the processing module 162, and the processing module 162 determines whether the ultraviolet LED12 reduces the illumination intensity 120 due to the driving device 14 to affect the sterilization process. If the reason for affecting the illumination intensity 120 of the ultraviolet LED12 appears, the processing module 162 may determine to extend the operation time 140 of the driving module 14 to increase the illumination time 122 to compensate for the lack of the illumination intensity 120, and maintain the sterilization process. Of course, if the processing module 162 receives the detection signal 1600 and finds that the operating temperature index of the driving device 14 is higher/abnormal, the driving device 14 may be directly stopped to maintain the basic operations of the driving device 14 and the ultraviolet LED 12.
In summary, the ultraviolet LED package structure of the present invention integrates the ultraviolet LED, the driving device, the control device, the indicator light and other structures on a substrate for packaging. Meanwhile, the control device controls the ultraviolet LED, the driving device and the indicator light in a central control management mode, so that the ultraviolet LED packaging structure can maintain and improve the sterilization efficiency, and has the mechanism advantages of overheat/overload protection of the driving device, and the effects of warning a user to detect the brightness change of the indicator light and judging whether the operation of the ultraviolet LED is normal and the like.
