Detailed Description

In view of the above problems, an embodiment of the present utility model provides a disinfection lamp, where a first communication module and a controller are provided in the disinfection lamp, and a second communication module is provided in the controller, where the second communication module may be in communication connection with the first communication module, so that relevant information of a lamp tube may be read from the first communication module, and the controller may perform corresponding control operation based on the read information. The read lamp tube information is different, and the subsequently executed control operation is also different, so that different requirements of users can be met, and the user experience of the disinfection lamp is improved.

In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

Referring to fig. 1, the present utility model provides a disinfection light fixture, which may comprise: a lamp 11, a first communication module 111, a second communication module 12, and a controller 13. Wherein:

the first communication module 111 is fixed on the lamp 11, adapted to store information about the lamp 11, and communicates with the controller 13;

the second communication module 12 is in communication connection with the first communication module 111;

the controller 13 is connected to the second communication module 12, and is adapted to read, from the first communication module 111, related information of the lamp 11 through the second communication module 12, and perform a corresponding control operation based on the read information;

wherein, the related information of the lamp 11 includes at least one of the following: remaining life information of the lamp 11; the identity information of the lamp tube 11; power information of the lamp 11.

In a specific implementation, the disinfection lamp is provided with a housing, and the lamp 11, the first communication module 111, the second communication module 12 and the controller 13 are disposed in the housing.

In a specific implementation. The lamp vessel 11 may be placed in a lamp socket of the housing. In one embodiment, the lamp 11 is internally filled with a dischargeable gas, which may be composed of a rare gas and a halogen or halide. When the electrodes of the lamp 11 are connected to a power source, an arc is generated inside the lamp 11, which excites the dischargeable gas to generate corresponding excimer molecules. The excited excimer molecules emit ultraviolet light at 222nm or 254nm when they transition down to the ground state.

In a specific implementation, the communication connection between the first communication module 111 and the second communication module 12 may be any of short-range wireless communication connections. Such as radio frequency identification (Radio Frequency Identification, RFID), bluetooth, infrared, etc.

In an embodiment of the utility model, the communication connection between the first communication module 111 and the second communication module 12 is near field communication (Near Field Communication, NFC). NFC communication is a short-distance high-frequency wireless communication technology, the working frequency of the NFC communication is 13.56MHz, and the communication distance is within 10 cm.

When the NFC communication connection is established between the first communication module 111 and the second communication module 12, the first communication module 111 may be an NFC electronic tag, and correspondingly, the second communication module 12 may be an NFC read-write module. The NFC electronic tag can store the related information of the lamp tube, and is convenient to read and write, convenient to install and low in cost. And the NFC read-write module performs information interaction with the NFC electronic tag through a radio frequency carrier wave of 13.56 MHz. The NFC read-write module can write information into the NFC electronic tag, and can read information from the NFC electronic tag. Be provided with NFC antenna on the NFC read-write module, NFC communication is near field communication, and NFC label and NFC antenna's distance suggestion control is within 5cm, avoids influencing communication effect.

In an implementation, the first communication module 111 may be fixed to the lamp tube 11 in various manners, which is not limited herein. For example, it can be fixed to the side wall of the lamp tube 11 by means of adhesion. The first communication module 111 should be located at a position on the lamp tube 11 as far away from the heat source and the metal material as possible, so as to avoid the heat source and the metal material from affecting communication. Taking the example of establishing NFC communication connection between the first communication module 111 and the second communication module 12, the NFC read-write module is provided with an NFC antenna, and a metal material cannot block radio frequency signals between the NFC antenna and the NFC electronic tag, so that normal communication is not affected.

In particular implementations, the second communication module 12 may be coupled to the controller 13 in a variety of ways. For example, the second communication module 12 may be connected to the controller 13 via a serial bus. The controller 13 accesses the first communication module 11 through the second communication module 12, whereby information interaction between the controller 13 and the first communication module 11 can be completed.

In the standard GB28235 for the use of disinfection lamps, the illumination of an ultraviolet light source has the parameter requirement of effective service life. Specifically, when the illuminance value of the uv light source is lower than 70% of the rated illuminance (i.e., the illuminance declared by the merchant under the rated environment), a new uv light source must be replaced, otherwise, a good killing effect is not achieved, and the duration of time from the initial illuminance to 70% of the initial illuminance is the effective life of the uv light source. Standard GB28235 specifies that the useful life of uv light sources should be greater than 1000 hours and that the useful life of commercial uv light sources is substantially greater than 8000 hours.

Because the user can not accurately know the accumulated use time length of the ultraviolet light source, in order to ensure the disinfection effect, the ultraviolet light source can be replaced regularly, for example, the user can replace the light source once a year, but the mode of replacing the light source regularly has the following two defects: 1. when the actual use time of the ultraviolet light source is short, the ultraviolet light source is likely to be replaced in advance by replacing the light source once a year, so that the use cost is increased; 2. when the actual service time of the ultraviolet light source is long, the ultraviolet light source is likely to be replaced after one time of year, and the subsequent disinfection effect is further deteriorated.

For example, 1 ultraviolet light source with a useful life of 8000 hours may be used for 333 days (approximately 1 year) if it is used for 24 hours per day. If used for 8 hours per day, 1000 days (approximately 3 years) may be used. Thus, if the uv light source is changed once a year, the cost of use is undoubtedly increased for users who do not use the disinfection light fixture continuously.

In order to facilitate the user to know the remaining life of the lamp, to avoid increasing the use cost or deteriorating the killing effect, in an embodiment of the present utility model, the first communication module 11 may store the remaining life information of the lamp. Accordingly, referring to fig. 2, the sterilizing light device may further include: an information display module 14. The information display module 14 is connected to the controller 13, and is adapted to display the remaining lifetime of the lamp 11 under the control of the controller 13 after the second communication module 12 reads the remaining lifetime information of the lamp.

In a specific implementation, the information display module 14 may be fixed on the outer side of the housing of the disinfection lamp, and may specifically be composed of devices with specific display functions such as an LED display screen. The information display module 14 may display the remaining life of the lamp under the control of the controller 13. The specific display mode may be text display, image display, or the like, and is not limited herein.

In a specific implementation, the second communication module 12 may write the remaining lifetime information of the lamp 11 to the first communication module 111 before the power-down of the disinfection lamp, and read the remaining lifetime information of the lamp from the first communication module 111 after the power-up of the disinfection lamp. Specifically, the controller 13 may detect whether the sterilizing lamp is about to be powered down, and write the remaining life information of the lamp tube 11 to the first communication module 111 through the second communication module 12 before the power down, and further may read the remaining life information of the lamp tube from the first communication module 111 after the next power up. Thus, when the sterilizing lamp is powered on again, the user can conveniently know the remaining life of the lamp 11 under the control of the controller 13, so that it can be convenient to determine whether the lamp 11 needs to be replaced. After the new lamp tube is replaced, the remaining service life of the lamp tube can be read again, so that a user can know the remaining service life of the new lamp tube.

In a specific implementation, the first communication module 111 may only have a function of storing information. At this time, the controller 13 may directly access the first communication module 111 to read or write the relevant information of the lamp without providing the second communication module 12 in the disinfection lamp. For example, the first communication module 111 may be a charged erasable programmable read-only memory (Electrically Erasable Programmable read only memory, EEPROM). The controller 13 is connected with the EEPROM in a wired manner, and realizes reading and writing of information.

In an embodiment, the information display module 14 is further adapted to prompt replacement of the lamp 11 when the remaining lifetime of the lamp is below a preset lifetime threshold. The preset service life threshold value can be set according to actual standard requirements. When the remaining life of the lamp 11 is below the preset life threshold, it is indicated that the cumulative service life of the lamp exceeds the specified useful life. By prompting the remaining life of the lamp 11, the user can be actively reminded to replace the lamp, and the time for replacing the lamp is prevented from being delayed.

In one embodiment, the remaining lifetime of the lamp may be calculated by the controller 13. Specifically, referring to fig. 2, the controller 13 may include: the remaining life calculation module 131 and the output control module 132. Wherein:

the remaining life calculating module 131 is adapted to calculate a remaining life of the lamp tube;

the output control module 132 is connected to the second communication module 12, and is adapted to control the information display module 14 to display the remaining lifetime of the lamp 11 after the second communication module 12 reads the remaining lifetime information of the lamp.

In a specific implementation, there are various influencing factors for the service life of the lamp 11, and in particular, the remaining service life of the lamp 11 may be calculated by combining various factors that influence the service life of the lamp. For example, frequent switching of the lamp can reduce the service life of the gas UV lamp. The gas ultraviolet lamp can be normally lightened only by high-voltage excitation, and the high voltage can damage electrodes on the gas ultraviolet lamp, so that the service life of an ultraviolet light source is shortened.

In an embodiment, the disinfection light fixture may further comprise: a temperature acquisition module 15. The temperature acquisition module 15 is adapted to acquire the ambient temperature around the lamp 11, and determine the damage of the high voltage to the electrode on the lamp by acquiring the ambient temperature around the lamp 11, so as to calculate the accumulated use time of the disinfection lamp. The ambient temperature around the lamp 11 refers to the ambient temperature around the lamp in the disinfection lamp.

Correspondingly, the remaining life calculating module 131 is adapted to calculate the accumulated usage time of the lamp 11 based on the ambient temperature around the lamp 11 and the number of times of turning on/off the lamp, and calculate the remaining life of the lamp based on the accumulated usage time of the lamp. Based on the ambient temperature around the lamp 11 and the number of times of turning on/off the lamp, the service life of the lamp after the last power-on can be calculated, and the accumulated service life of the lamp can be calculated by combining the remaining service life of the lamp obtained during the last power-on.

Specifically, assuming that t is the actual use duration of the ith power-on, si is the influence coefficient of the power-on and power-off to the service life of the disinfection lamp in the ith power-on process, ti is the influence coefficient of the ambient temperature of the lamp tube to the service life of the disinfection lamp in the ith power-on process, and the correction is performed on t by using Si and Ti, so that the corrected use duration of the lamp tube after the ith power-on is ti=t×sn×tn. The accumulated service time from the initial power-up to the end of the nth power-up of the lamp tube isThe difference between the effective life of the lamp and the accumulated service time is used as the remaining life of the lamp when the lamp is powered on for the n+1th timeWherein L is ₀ Is the effective life of the lamp. Before each power failure, the controller can update the remaining life of the lamp tube.

In practical application, the lamp 11 cannot be anti-counterfeiting, so that a fake lamp is arranged in a sterilizing lamp on the market, and the use safety of the sterilizing lamp is affected.

In another embodiment of the present utility model, the information about the lamp includes: and the identity information of the lamp tube. The controller 13 can perform identity authentication on the lamp based on the identity information of the lamp 11 to confirm whether the lamp is a counterfeit product.

Specifically, referring to fig. 3, the disinfection lamp may include: a ballast 16, the ballast 16 is connected to the controller 13, and is adapted to drive the lamp 11 under the control of the controller 13.

The controller 13 may include: the authentication module 133 and the ballast control module 134. The authentication module 133 is connected to the second communication module 12, and is adapted to perform identity authentication on the lamp 11 after the second communication module 12 reads the identity information of the lamp 11. The ballast control module 134 is connected to the authentication module 133 and adapted to control the ballast 16 to be turned on or off based on an authentication result of the authentication module 133.

In a specific implementation, the identity information of the lamp 11 is information that uniquely identifies the identity of the lamp 11. Based on this information, the brand, model, etc. of the lamp 11 can be determined. After the authentication module 133 obtains the identity information of the lamp 11, the obtained identity information of the lamp 11 may be compared with the pre-stored identity information of the lamp 11, and when the obtained identity information of the lamp 11 is consistent with the pre-stored identity information of the lamp, the lamp 11 is considered to pass the authentication, otherwise, the lamp 11 fails the authentication. When the lamp 11 is authenticated, the ballast control module 134 may send a lamp turn-on command to the ballast 16 to turn on the ballast 16 to drive the lamp 11 into operation. When the lamp 11 fails the authentication, the ballast control module 134 may send a lamp turn-off command to the ballast, thereby controlling the ballast 16 to turn off to stop the lamp 11 from operating.

In the existing disinfection lamp, the ballasts cannot be automatically matched with the lamp tubes 11 with different power levels, and the ballasts with different power levels need to be replaced. If the power levels of the ballast and the lamp tube are not matched, abnormal phenomena of poor safety risk and poor disinfection effect can be caused.

In order to enable the same ballast to be matched to lamps 11 of different power levels, in an embodiment, with continued reference to fig. 3, power information of the lamps 11 may be stored in the first communication module 111, and the ballast control module 134 may also adjust parameters of the ballast 16 based on the power information of the lamps so that the ballast 16 is matched to the power of the lamps 11.

In implementations, the ballast control module 134 may adjust parameters of the ballast 16 to match the power of the lamp 11 after the lamp 11 passes the identity authentication. For example, the power of the ballast 16 may be varied by adjusting the output voltage and frequency of the ballast 16 such that the power of the ballast 16 and the power of the lamp are substantially uniform, thereby better driving the lamp to improve safety of use and disinfection.

In the implementation, the related information of the lamp may include only any one of the remaining lifetime information of the lamp, the identity information of the lamp, and the power information of the lamp, or may include two or more of the remaining lifetime information of the lamp, the identity information of the lamp, and the power information of the lamp. When the related information of the lamp includes two or more of remaining lifetime information of the lamp, identification information of the lamp, and power information of the lamp, the controller and the sterilizing lamp may be configured as described in the above embodiments, so as to meet the requirement of performing control operation when each single information is included.

For example, referring to fig. 4, when the related information of the lamp includes both the remaining lifetime information of the lamp and the identification information of the lamp, the controller 13 may include the remaining lifetime calculation module 131, the output control module 132, the authentication module 133, and the ballast control module 134. Accordingly, the disinfection lamp can comprise a temperature acquisition module 15 and an information display module 14.

As another example, referring to fig. 4, when the related information of the lamp includes both the identification information of the lamp and the power information of the lamp, the controller 13 may include an authentication module 133 and a ballast control module 134.

Fig. 5 is a schematic diagram illustrating a working process of the disinfection lamp according to an embodiment of the utility model. Referring to fig. 5, in an implementation, the controller may read the lamp identification information and the lamp power level information stored in the NFC electronic tag through the NFC read/write module. The controller performs identity authentication on the lamp based on the lamp identity information. If the lamp identity authentication fails, the controller can control the ballast to be closed. If the lamp identity authentication is successful, the controller may determine a lamp power level based on the lamp power level information and send a power command to the ballast based on the lamp power level to adjust the ballast power.

In a specific implementation, the controller may write the effective lifetime of the lamp tube to the NFC electronic tag. The subsequent controller can also acquire the ambient temperature data of the lamp tube and calculate the remaining life of the lamp tube based on the ambient temperature data of the lamp tube and the effective life of the lamp tube. And prompting to replace the lamp tube when the remaining service life of the lamp tube is lower than a preset service life threshold value.

By adopting the scheme of the utility model, the actual service life of the disinfection lamp is longest, the use cost is reduced, and the deterioration of the disinfection effect caused by the fact that the service life of the disinfection lamp is longer than the effective life can be avoided. In addition, the controller can also authenticate the identity of the lamp tube, avoid using error or fake lamp tube, and optimize the disinfection effect. The controller can also match the power of the lamp tube and the ballast, so that the same ballast can be matched with the lamp tubes with various power levels, the cost is reduced, the unmatched use of the lamp tube and the ballast can be reduced, and the potential safety hazard is reduced.

Although the present utility model is disclosed above, the present utility model is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the utility model, and the scope of the utility model should be assessed accordingly to that of the appended claims.
