Of course, the mounting slots 16 are evenly spaced around the geometric center of the ultraviolet light panel 12 in a ring arrangement; the angle adjustment means abuts against the geometric centre of the uv light panel 12. Thus, the angle adjusting device is located at the geometric center of the ultraviolet panel 12, on one hand, the ultraviolet panel 12 can be guaranteed to have the maximum deformation effect under the abutting of the angle adjusting device 14, the ultraviolet irradiation range and the disinfection and sterilization functions are indirectly guaranteed, and on the other hand, the situation that the ultraviolet panel 12 is subjected to rapid structural fatigue caused by uneven stress distribution for a long time due to uneven stress distribution or abutting at a position deviating from the geometric center so as to reduce the service life of the ultraviolet panel 12 is also avoided.
For the angle adjuster 14, the angle adjusting means includes a driving power source 141 and an actuator 142; the driving power supply 141 is connected to the capping housing 11 and is disposed opposite to the ultraviolet panel 12; one end of the actuator 142 is connected to the driving power supply 141, and the other end abuts against the ultraviolet panel 12. The angle adjusting device drives the actuator 142 to move through the power supply, can effectively support the ultraviolet panel 12 to deform, further changes the angle and the position irradiated by the ultraviolet lamp embedded on the ultraviolet panel 12, realizes the change of the irradiation area, improves the adaptability of the far ultraviolet disinfection panel lamp to different spaces, and further improves the disinfection effect.
It can be understood that the actuator 142 drives the ultraviolet panel 12 to approach the planar filter 13, so as to ensure that the far ultraviolet lights emitted by the far ultraviolet lamps 17 on the two sides of the lighting module 02 converge on the geometric central plane position of the lighting module 02 along the vertical direction. In order to avoid that the far ultraviolet modules 01 located at two sides of the illumination module 02 cannot irradiate the lower space region corresponding to the illumination module 02, the angle adjuster 14 actuates the amount of deformation of the ultraviolet light panel 12, so that the ultraviolet light at two sides at least can be converged at the central position of the lower space corresponding to the illumination module 02.
In addition, the angle adjusting device further includes a position sensor 144 and a controller 143; the position sensor 144 is arranged at one end of the capping housing 11, and the position sensor 144 is close to the lighting module 02; the controller 143 is connected to the driving power supply 141 and the position sensor 144. The position sensor 144 can monitor the deformation amount of the ultraviolet light panel 12, and the controller 143 collects data to control the operation of the angle adjuster 14, so as to effectively ensure that the angle adjuster 14 operates within a proper movement range, and avoid the situation that the deformation of the angle adjuster 14 against the ultraviolet light panel 12 exceeds the deformation limit of the material of the ultraviolet light panel 12, which damages the plane of the ultraviolet light.
The installation relationship between the lighting module 02 and the far ultraviolet module 01 also has a certain influence on the disinfection and sterilization effect. Therefore, the illumination plane of the illumination module 02 is lower than that of the extreme ultraviolet module 01. The illumination plane of the far ultraviolet module 01 is lower than that of the illumination module 02, so that the condition that the illumination of the far ultraviolet module 01 cannot be shielded by the illumination module 02 to generate an illumination blind area can be avoided.
The controller 143 may be a processor or a data processing center or a data processing base station in various forms, and in the present invention, the controller 143 uses an industrial PLC controller to collect and process the monitoring data of the position sensor 144, and controls the driving power supply 141 to be turned on and off to control the actuator 142. For the position sensor 144, it may be a laser range finder, or a piezoelectric sensor, etc., in this embodiment, the position sensor 144 is a piezoelectric sensor, and the position sensor 144 obtains deformation parameters through deformation extrusion of the ultraviolet light panel 12.
The plane filter 13 has various specific structures and forms, but the parameter function of the filter is to ensure that the ultraviolet light has effective disinfection and sterilization effects. In the embodiment of the invention, the thickness of the planar optical filter 13 is not more than 1mm, the transmittance of the planar optical filter to far ultraviolet light with the wavelength of 200 nm-230 nm is not less than 70%, and the transmittance of the planar optical filter to far ultraviolet light with the wavelength of more than 230nm is not more than 5%.
In conclusion, the ultraviolet light with the wavelength range within the range of 200 nm-230 nm is used for illumination and disinfection, the ultraviolet light can act together with the illumination module 02, and is not influenced by personnel, the ultraviolet light under the waveband can kill bacteria, is friendly to human eyes and skin, and can not cause ultraviolet damage, on the one hand, the disinfection process is effectively realized, on the other hand, the auxiliary device for controlling the opening and closing of the human body by additionally arranging the position of an induction person due to the damage to the human body is avoided, meanwhile, the technical design point for avoiding the irradiation of the personnel can be omitted, the design difficulty is reduced, and meanwhile, the effective disinfection of the whole space area is ensured.
The ultraviolet lamp is a krypton-chlorine excimer lamp, but the difference is that the mounting groove 16 arranged on the ultraviolet panel 12 is used as the outer shell of the krypton-chlorine excimer lamp, and the mounting groove is also used as the low-voltage end of the krypton-chlorine excimer lamp, so that the assembly and manufacturing cost of the krypton-chlorine excimer lamp can be reduced, the krypton-chlorine excimer lamp and the ultraviolet panel 12 are integrated, the mounting stability of the krypton-chlorine excimer lamp is ensured, and the effective utilization of the ultraviolet panel 12 is fully realized.
Since the angle adjusting device needs to abut against the ultraviolet panel 12 to make the ultraviolet panel 12 deform in a concave manner, so as to change the angle range of the ultraviolet irradiation region, in order to ensure that the groove bottom of the installation groove 16 does not contact or interfere with the planar filter 13, the depth of the installation groove 16 is properly adjusted according to the position of the angle adjuster 14, which can effectively avoid the situation.
The angle adjusting device drives the actuator 142 to move through the power supply, can effectively support the ultraviolet panel 12 to deform, further changes the angle and the position irradiated by the ultraviolet lamp embedded on the ultraviolet panel 12, realizes the change of the irradiation area, improves the adaptability of the far ultraviolet disinfection panel lamp to different spaces, and further improves the disinfection effect.
In order to avoid that the far ultraviolet modules 01 located at two sides of the illumination module 02 cannot irradiate the lower space region corresponding to the illumination module 02, the angle adjuster 14 actuates the amount of deformation of the ultraviolet light panel 12, so that the ultraviolet light at two sides at least can be converged at the central position of the lower space corresponding to the illumination module 02.
The position sensor 144 can monitor the deformation of the uv panel 12 and the controller 143 can collect data to control the operation of the angle adjuster 14, so as to effectively ensure that the angle adjuster 14 operates within a proper motion range, and avoid the situation that the deformation of the uv panel 12 against the angle adjuster 14 exceeds the deformation limit of the material of the uv panel 12, which may damage the plane of the uv lamp.
The illumination plane of the far ultraviolet module 01 is lower than that of the illumination module 02, so that the condition that the illumination of the far ultraviolet module 01 cannot be shielded by the illumination module 02 to generate an illumination blind area can be avoided.
The angle adjusting device is located at the geometric center of the ultraviolet panel 12, so that on one hand, the ultraviolet panel 12 can be guaranteed to have the maximum deformation effect under the abutting of the angle adjusting device 14, the ultraviolet irradiation range and the disinfection and sterilization functions are indirectly guaranteed, and on the other hand, the situation that the ultraviolet panel 12 is stressed unevenly or abuts at the position deviated from the geometric center to cause long-term stress distribution uneven to cause rapid structural fatigue so as to reduce the service life of the ultraviolet panel 12 is avoided.
