When the germicidal lamp 10 of the above-mentioned embodiment is used, external air enters the gas flow channel 111 from the air inlet 1111 of the gas flow channel 111, and the germicidal light 210 emitted by the optical germicidal device 200 can irradiate the air flowing through the gas flow channel 111, so as to kill bacteria or viruses in the air, and the purified air flows out from the air outlet 1112 of the gas flow channel 111, so as to ensure the air safety of the environment. Meanwhile, when the sterilizing light 210 emitted by the optical sterilizing member 200 passes through the gas flow channel 111 and then irradiates the first converting assembly 310 of the converting structure 300, the sterilizing light 210 is converted into the first illuminating light 220 by the first converting assembly 310, and the first illuminating light 220 is output to the outside through the light emergent region 112, so that the outside can be illuminated; when the sterilizing light 210 emitted by the optical sterilizing member 200 passes through the gas flow channel 111 and then irradiates the second converting assembly 320 of the converting structure 300, the sterilizing light 210 is converted into the second illuminating light 230 by the second converting assembly 320, and the second illuminating light 230 is output to the outside through the light emergent region 112, so that the outside can be illuminated. In addition, the first conversion module 310 and the second conversion module 320 are alternately arranged corresponding to the optical sterilizing member 200 by the switching mechanism, so that the first illumination light 220 or the second illumination light 230 with different colors can be output according to actual needs, the sterilizing lamp 10 can not only perform illumination, but also change the color of the illumination light according to use requirements on the basis of having a sterilizing function, and the sterilizing lamp has various functions and meets diversified use requirements.

Compared with the conventional germicidal lamp 10, the germicidal lamp 10 of the embodiment has the functions of sterilization and illumination, can provide illumination while sterilizing air, and is more convenient to use. Moreover, the conventional germicidal lamp fixture 10 mainly integrates the germicidal light source and the illumination light source to realize the germicidal and illumination functions, the conventional germicidal lamp fixture 10 can sterilize and illuminate only by simultaneously turning on the germicidal light source and the illumination light source, the germicidal lamp fixture 10 of the above embodiment can simultaneously realize the germicidal and illumination functions only by means of the optical germicidal element 200, and the energy consumption is low. The conventional germicidal lamp 10 is provided with the germicidal light source and the illumination light source at the same time, the internal structure is complex, the germicidal lamp 10 of the embodiment is provided with only one optical germicidal member 200, and the germicidal lamp is simple and compact in structure and low in cost. The conventional germicidal lamp fixture 10 integrates a germicidal light source and an illumination light source, and can only emit illumination light of a single color, and the germicidal lamp fixture 10 of the above embodiment can flexibly change the color of the output illumination light according to actual needs, so that the functions are more diverse and complete.

It should be noted that the optical sterilization member 200 may be any component capable of Emitting the sterilization light 210, preferably an ultraviolet light source, such as L ED (L light Emitting Diode) ultraviolet lamp, a mounting hole communicating with the gas flow channel 111 may be provided on the housing 100, the optical sterilization member 200 may be mounted in the mounting hole such that the light Emitting end of the optical sterilization member 200 fully or partially extends into the gas flow channel 111, the input end of the optical sterilization member 200 may extend out of the mounting hole and be connected to an external power source, a sealing member such as a sealing ring or a sealing strip may be provided between the optical sterilization member 200 and the housing 100 to ensure a tight seal between the optical sterilization member 200 and the housing 100 to avoid air leakage, the first illumination light 220 and the second illumination light 230 may be any light capable of serving as illumination, and in other embodiments, the sterilization light 210 may be converted into light of other wavelength bands by the conversion structure 300, such as a non-visible light outlet 112, a light outlet, and the like, and a structure for allowing the first illumination light 220 and the second illumination light 230 to pass through.

It should be emphasized that, under the actual use needs or other circumstances, the conversion structure 300 may further include a third conversion component 330 (see fig. 2 and 3) or a fourth conversion component 340 (see fig. 3) or more conversion components, the third conversion component 330 may convert the germicidal light rays 210 into third illumination light rays 240 (see fig. 3) to be output from the light-emitting area 112, the fourth conversion component 340 may convert the germicidal light rays 210 into fourth illumination light rays (not shown) to be output from the light-emitting area 112, the first illumination light 220, the second illumination light 230, the third illumination light rays 240 and the fourth illumination light rays may all be different colors, since the related structure, the positional relationship or the principle of the third conversion component 330 or the fourth conversion component 340 is the same as or similar to that of the first conversion component 310 and the second conversion component 320, in order to facilitate the description of the related principle of the germicidal lamp 10, the following embodiments are only described with the conversion structure 300 comprising the first conversion component 310 and the second conversion component 320, and cannot be interpreted that the conversion structure 300 comprises only the first conversion component 310 and the second conversion component 320.

The conversion structure 300 converts the sterilization light 210 into the first illumination light 220 and the second illumination light 230, and can change the wavelength of the sterilization light 210 through a lens, and also can excite a corresponding fluorescent substance through the sterilization light 210, and in addition, only the requirement that the sterilization light 210 can be converted into corresponding illumination light can be met through the combination of the lens and the fluorescent substance.

Referring to fig. 1, in an embodiment, the first conversion assembly 310 includes a first conversion lens 311 and a first fluorescent layer 312, and when the switching structure 400 enables the first conversion lens 311 to be disposed corresponding to the optical sterilization member 200, the first conversion lens 311 can change a propagation path of the sterilization light 210, so that the sterilization light 210 after the propagation path is converted can irradiate the first fluorescent layer 312 to emit the first illumination light 220 and is output from the light exit area 112. Thus, when the first conversion lens 311 moves to the position corresponding to the optical sterilization member 200 under the action of the switching structure 400 (for example, when the first conversion lens 311 moves to the position facing the optical sterilization member 200), the sterilization light 210 emitted by the optical sterilization member 200 firstly passes through the gas flow channel 111, and then irradiates the first conversion lens 311 after completing the sterilization of the air, and the first conversion lens 311 is used to change the propagation path of the sterilization light 210, so that the sterilization light 210 with the changed propagation path can accurately irradiate the first fluorescent layer 312, thereby exciting the fluorescent substance in the first fluorescent layer 312, and further emitting the first illumination light 220 with a longer wavelength and emitting from the light emitting area 112, thereby enabling illumination. The propagation path of the sterilization light 210 can be changed by using the first conversion lens 311, so that the position of the first fluorescent layer 312 can be flexibly changed, the propagation path of the first illumination light 220 is correspondingly changed, the emergent position or the emergent angle of the first illumination light 220 can be flexibly adjusted, the installation position or the installation angle of the sterilization lamp 10 can be reasonably adjusted, the universality is higher, and the use is more convenient.

Referring to fig. 1, in an embodiment, the optical sterilization member 200 may be disposed on the left side of the gas flow channel 111, the first conversion lens 311 is disposed on the right side of the gas flow channel 111, and when the first conversion lens 311 moves to be disposed corresponding to the optical sterilization member 200 under the action of the switching structure 400, the first conversion lens 311 is used to change the propagation path of the sterilization light 210 irradiated from the left side, so that the propagation path of the sterilization light 210 changes to be downward, so that the sterilization light 210 propagating downward can be directly irradiated onto the first fluorescent layer 312 disposed below the housing 100, and the fluorescent substance in the first fluorescent layer 312 is excited, so as to emit the first illumination light 220 downward, and the first illumination light 220 illuminates the lower side after passing through the light exit area 112 disposed below the housing 100. Of course, in other embodiments, the optical sterilization member 200 is disposed on the left side of the gas flow channel 111, the first conversion lens 311 is disposed on the right side of the gas flow channel 111, when the first conversion lens 311 moves to be disposed corresponding to the optical sterilization member 200 under the action of the switching structure 400, the first conversion lens 311 is used to change the propagation path of the sterilization light 210 irradiated from the left side, and the first conversion lens 311 may also be used to change the propagation path of the sterilization light 210 to be upward propagated, so that the upward propagated sterilization light 210 can be directly irradiated onto the first fluorescent layer 312 disposed above the housing 100, the fluorescent substance in the first fluorescent layer 312 is excited, and the first illumination light 220 is emitted upward, and the first illumination light 220 illuminates the upper side after passing through the light exit area 112 disposed above the housing 100.

The color of the fluorescent material in the first fluorescent layer 312 can be flexibly adjusted according to the usage requirement, so that the first illumination light 220 has a corresponding color, such as green or yellow; of course, it is also possible to partition the first fluorescent layer 312 and fill different areas with fluorescent materials of different colors, so that the fluorescent materials of different areas emit first illumination light 220 of different colors after being excited; meanwhile, different fluorescent substances can be selected to emit invisible light in other bands, such as infrared bands. The first fluorescent layer 312 may be configured to be circular or square, and the shape and size thereof may match the shape and size of the light exiting region 112. The first conversion lens 311 may be made of a transparent material such as glass or resin.

The change of the propagation path of the sterilizing light 210 by the first conversion lens 311 can be realized by refraction, total reflection and other ways, and only the propagation path of the sterilizing light 210 needs to be changed; preferably, the method is implemented by total reflection, and the propagation paths of all the germicidal light rays 210 can be changed to the greatest extent without loss, so that enough germicidal light rays 210 irradiate the first fluorescent layer 312, and the first fluorescent layer 312 can be ensured to be excited, thereby ensuring the intensity of the first illumination light 220.

Referring to fig. 1, in one embodiment, the first conversion lens 311 includes a first light-entering sidewall 3111, a first conversion sidewall 3112 and a first light-exiting sidewall 3113. When the switching structure 400 makes the first conversion lens 311 disposed corresponding to the optical sterilizing member 200, the first light-exiting sidewall 3113 is disposed corresponding to the light-exiting region 112, and the first light-entering sidewall 3111 is disposed perpendicular or approximately perpendicular to the sterilizing light 210. Thus, the sterilizing light 210 emitted by the optical sterilizing element 200 passes through the gas flow channel 111 to sterilize the air, and then is directly irradiated onto the first light-entering sidewall 3111, so that the sterilizing light 210 enters the first conversion lens 311 to the maximum, thereby avoiding the loss caused by the reflecting of the sterilizing light 210 on the first light-entering sidewall 3111 and ensuring the intensity of the sterilizing light 210 entering the first conversion lens 311. The first conversion sidewall 3112 and the germicidal light rays 210 may be disposed at an included angle, so that the first conversion sidewall 3112 can make the germicidal light rays 210 generate total reflection, and make the germicidal light rays 210 after total reflection vertically or approximately vertically transmit to the first fluorescent layer 312 disposed near the first light-emitting sidewall 3113. Thus, when the sterilizing light 210 entering the first conversion lens 311 irradiates the first conversion sidewall 3112, since the first conversion lens 311 belongs to a light-tight medium and the outside air belongs to a light-sparse medium, when the included angle between the sterilizing light 210 and the normal direction of the first conversion sidewall 3112 is greater than or equal to the critical angle (i.e. the incident angle is greater than or equal to the critical angle), the sterilizing light 210 is totally reflected on the first conversion sidewall 3112, so as to change the propagation path of the sterilizing light 210, so that the sterilizing light 210 irradiates the first fluorescent layer 312 disposed near the first light-emitting sidewall 3113, and by exciting the fluorescent material in the first fluorescent layer 312, the first illuminating light 220 with a longer wavelength is emitted, and further the first illuminating light 220 passes through the first light-emitting sidewall 3113 and then is emitted from the light-emitting region 112 for illumination. The germicidal light rays 210 are vertically or approximately vertically transmitted to the first light-exiting sidewall 3113, so that as many germicidal light rays 210 as possible are irradiated onto the first fluorescent layer 312, the excitation effect on the fluorescent substance of the first fluorescent layer 312 is good, and the intensity of the first illumination light 220 is ensured; further, the first fluorescent layer 312 may be disposed parallel or approximately parallel to the first light exit sidewall 3113, so that as much of the sterilizing light 210 as possible is irradiated onto the first fluorescent layer 312, and the first illuminating light 220 is also irradiated onto the first light exit sidewall 3113 perpendicularly or approximately perpendicularly, thereby preventing the first illuminating light 220 from being emitted on the first light exit sidewall 3113, avoiding the loss of the first illuminating light 220, and ensuring the intensity of the first illuminating light 220.

Referring to fig. 1, in an embodiment, the optical sterilizing member 200 is disposed at the left side of the gas flow channel 111, the first converting lens 311 is disposed at the opposite right side of the gas flow channel 111, when the switching structure 400 makes the first converting lens 311 disposed corresponding to the optical sterilizing member 200, the sterilizing light 210 irradiated from the left side is vertically irradiated onto the first light-entering sidewall 3111 disposed vertically, so that the sterilizing light 210 smoothly enters the first converting lens 311, when the sterilizing light 210 is irradiated onto the first converting sidewall 3112 disposed obliquely with respect to the horizontal plane, total reflection occurs, so that the propagation path of the sterilizing light 210 is changed to be vertically downward propagated, so that the sterilizing light 210 can be vertically irradiated onto the first fluorescent layer 312 disposed horizontally, the fluorescent material in the first fluorescent layer 312 is excited, thereby generating a first illuminating light 220 vertically downward, the first illuminating light 220 is vertically irradiated onto the first horizontally disposed sidewall 3113, and vertically output downward to the outside of the housing 100 after passing through the light exiting region 112.

The substantially perpendicular or substantially parallel arrangement in the present application is considered to be perpendicular or parallel within an error tolerance range in consideration of the influence of machining errors and mounting errors, and for example, is considered to be perpendicular when the included angle is 89 ° to 91 °, and is considered to be parallel when the included angle is 0 ° to 1 °. The size of the outline of the first fluorescent layer 312 can be larger than the size of the outline of the light emergent area 112, so that the contact area between the sterilizing light 210 and the first fluorescent layer 312 is increased, the sterilizing light 210 is prevented from leaking from the light emergent area 112, and the safety is ensured. The first fluorescent layer 312 may be disposed inside the first conversion lens 311, so that the first fluorescent layer 312 is prevented from being interfered by the outside, and the service life of the first fluorescent layer 312 is prolonged.

Referring to fig. 2, based on any of the above embodiments, the second conversion assembly 320 includes a second conversion lens 321 and a second fluorescent layer 322, and when the switching structure 400 enables the second conversion lens 321 to be disposed corresponding to the optical sterilization member 200, the second conversion lens 321 can change the propagation path of the sterilization light 210, so that the sterilization light 210 after the propagation path is converted can irradiate the second fluorescent layer 322 to emit the second illumination light 230 and is output from the light exit area 112. Thus, when the second conversion lens 321 moves to the position corresponding to the optical sterilization member 200 under the action of the switching structure 400 (for example, when the second conversion lens 321 moves to the position corresponding to the optical sterilization member 200), the sterilization light 210 emitted by the optical sterilization member 200 firstly passes through the gas flow channel 111, and then irradiates the second conversion lens 321 after completing the sterilization of the air, and the second conversion lens 321 is utilized to change the propagation path of the sterilization light 210, so that the sterilization light 210 with the changed propagation path can accurately irradiate the second fluorescent layer 322, thereby exciting the fluorescent material in the second fluorescent layer 322, and further emitting the second illumination light 230 with longer wavelength and emitting from the light emitting area 112, thereby enabling illumination. The propagation path of the sterilization light 210 can be changed by using the second conversion lens 321, so that the position of the second fluorescent layer 322 can be flexibly changed, the propagation path of the second illumination light 230 can be correspondingly changed, the emergent position or the emergent angle of the second illumination light 230 can be flexibly adjusted, the installation position or the installation angle of the sterilization lamp 10 can be reasonably adjusted, the universality is higher, and the use is more convenient.

Referring to fig. 2, in an embodiment, the optical sterilization member 200 may be disposed at the left side of the gas flow channel 111, the second conversion lens 321 is disposed at the right side of the gas flow channel 111, and when the second conversion lens 321 moves to be disposed corresponding to the optical sterilization member 200 under the action of the switching structure 400, the second conversion lens 321 is used to change the propagation path of the sterilization light 210 irradiated from the left side, so that the propagation path of the sterilization light 210 changes to be downward, the sterilization light 210 propagating downward can be directly irradiated onto the second fluorescent layer 322 disposed below the housing 100, the fluorescent substance in the second fluorescent layer 322 is excited, and the second illumination light 230 is emitted downward, and the second illumination light 230 illuminates below after passing through the light emitting area 112 disposed below the housing 100. Of course, in other embodiments, the optical sterilization member 200 is disposed on the left side of the gas flow channel 111, the second conversion lens 321 is disposed on the right side of the gas flow channel 111, when the second conversion lens 321 moves to be disposed corresponding to the optical sterilization member 200 under the action of the switching structure 400, the second conversion lens 321 is used to change the propagation path of the sterilization light 210 irradiated from the left side, and the second conversion lens 321 may also be used to change the propagation path of the sterilization light 210 to be upward propagated, so that the upward propagated sterilization light 210 can be directly irradiated onto the second fluorescent layer 322 disposed above the housing 100, the fluorescent substance in the second fluorescent layer 322 is excited, and the second illumination light 230 is emitted upward, and the second illumination light 230 illuminates the upper side after passing through the light exit area 112 disposed above the housing 100.

The color of the fluorescent material in the second fluorescent layer 322 can be flexibly adjusted according to the usage requirement, so that the second illumination light 230 has a corresponding color, such as green or yellow; of course, it is also possible to partition the second fluorescent layer 322 and fill different areas with fluorescent substances of different colors, so that the fluorescent substances of different areas emit second illumination light 230 of different colors after being excited; meanwhile, different fluorescent substances can be selected to emit invisible light in other bands, such as infrared bands. The second fluorescent layer 322 may be configured to be circular or square, and the shape and size thereof may match the shape and size of the light emergent region 112. The second conversion lens 321 can be made of a transparent material such as glass or resin.

The second conversion lens 321 can change the propagation path of the sterilizing light 210 by refraction, total reflection, and the like, and only the propagation path of the sterilizing light 210 needs to be changed; preferably, the total reflection is adopted, so that the propagation paths of all the sterilizing light rays 210 can be changed to the greatest extent, no loss occurs, enough sterilizing light rays 210 are irradiated on the second fluorescent layer 322, and the second fluorescent layer 322 can be ensured to be excited, so that the intensity of the second illumination light 230 is ensured.

Referring to fig. 2, in an embodiment, the second convertible lens 321 includes a second light-entering sidewall 3211, a second convertible sidewall 3212 and a second light-exiting sidewall 3213. When the switching structure 400 makes the second conversion lens 321 disposed corresponding to the optical sterilizing element 200, the second light-exiting sidewall 3213 is disposed corresponding to the light-exiting region 112, and the second light-entering sidewall 3211 is perpendicular or approximately perpendicular to the sterilizing light 210. Therefore, the sterilizing light 210 emitted by the optical sterilizing element 200 passes through the gas flow channel 111 to sterilize the air, and then is directly irradiated onto the second light-entering side wall 3211, so that the sterilizing light 210 enters the second conversion lens 321 to the maximum, thereby avoiding the loss caused by the reflecting of the sterilizing light 210 on the second light-entering side wall 3211, and ensuring the intensity of the sterilizing light 210 entering the second conversion lens 321. The second conversion sidewall 3212 and the germicidal light rays 210 may form an included angle, so that the second conversion sidewall 3212 can make the germicidal light rays 210 generate total reflection, and make the germicidal light rays 210 after total reflection vertically or approximately vertically transmit to the second fluorescent layer 322 disposed near the second light-emitting sidewall 3213. Thus, when the sterilizing light 210 entering the second converting lens 321 irradiates the second converting sidewall 3212, since the second converting lens 321 belongs to a light-tight medium and the outside air belongs to a light-sparse medium, when an included angle between the sterilizing light 210 and a normal direction of the second converting sidewall 3212 is greater than or equal to a critical angle (i.e., an incident angle is greater than or equal to the critical angle), the sterilizing light 210 is totally reflected on the second converting sidewall 3212, so as to change a propagation path of the sterilizing light 210, so that the sterilizing light 210 irradiates the second fluorescent layer 322 disposed near the second light emitting sidewall 3213, and by exciting the fluorescent substance in the second fluorescent layer 322, the second illuminating light 230 with a longer wavelength is emitted, and further, the second illuminating light 230 passes through the second light emitting sidewall 3213 and then is emitted from the light emitting region 112 for illumination. The germicidal light rays 210 are vertically or approximately vertically transmitted to the second light-emitting sidewall 3213, so that as many germicidal light rays 210 as possible are irradiated onto the second fluorescent layer 322, the excitation effect on the fluorescent substance of the second fluorescent layer 322 is good, and the intensity of the second illumination light 230 is ensured; further, the second fluorescent layer 322 may be disposed parallel or approximately parallel to the second light exit sidewall 3213, so that as much germicidal light rays 210 as possible are irradiated onto the second fluorescent layer 322, and the second illumination light 230 is also irradiated onto the second light exit sidewall 3213 vertically or approximately vertically, thereby preventing the second illumination light 230 from being emitted on the second light exit sidewall 3213, avoiding the loss of the second illumination light 230, and ensuring the intensity of the second illumination light 230.

Referring to fig. 2, in an embodiment, the optical sterilizing member 200 is disposed at the left side of the gas flow channel 111, the second conversion lens 321 is disposed at the opposite right side of the gas flow channel 111, when the switching structure 400 makes the second conversion lens 321 disposed corresponding to the optical sterilizing member 200, the sterilizing light 210 irradiated from the left side is vertically irradiated onto the second light-entering sidewall 3211 disposed vertically, so that the sterilizing light 210 smoothly enters the second conversion lens 321, when the sterilizing light 210 is irradiated onto the second conversion sidewall 3212 disposed obliquely with respect to the horizontal plane, total reflection occurs, so that the propagation path of the sterilizing light 210 is changed to vertically downward propagation, so that the sterilizing light 210 can be vertically irradiated onto the second 322 disposed horizontally, so as to excite the fluorescent material in the second fluorescent layer 322, thereby generating a second illuminating light 230 vertically downward, the second illuminating light 230 is vertically irradiated onto the second light-exiting sidewall 3213 disposed horizontally, and vertically output downward to the outside of the housing 100 after passing through the light exiting region 112.

It should be noted that the size of the outline of the second fluorescent layer 322 may be set to be larger than the size of the outline of the light exit area 112, so as to increase the contact area between the germicidal light rays 210 and the second fluorescent layer 322, avoid the germicidal light rays 210 from leaking from the light exit area 112, and ensure safety. The second fluorescent layer 322 can be disposed inside the second conversion lens 321, so that the second fluorescent layer 322 can be prevented from being interfered by the outside, and the service life of the second fluorescent layer 322 can be prolonged.

Thus, when the switching structure 400 moves the third fluorescent layer to a position between the optical sterilizing member 200 and the light exit region 112, the sterilizing light 210 emitted by the optical sterilizing member 200 firstly passes through the gas flow channel 111, and then irradiates the third fluorescent layer after completing the sterilization of air, so as to excite the fluorescent substance in the third fluorescent layer, and further emit the first illuminating light 220 with longer wavelength, and the first illuminating light 220 penetrates out of the light exit region 112 to be capable of illuminating; when the switching structure 400 moves the fourth fluorescent layer to a position between the optical sterilizing member 200 and the light exit region 112, the sterilizing light 210 emitted by the optical sterilizing member 200 firstly passes through the gas flow channel 111, and then irradiates the fourth fluorescent layer after the air sterilization is completed, so as to excite the fluorescent substance in the fourth fluorescent layer, and further emit the second illumination light 230 with longer wavelength, and the second illumination light 230 passes through the light exit region 112, so as to illuminate. The sterilizing light 210 is directly irradiated to the third fluorescent layer or the fourth fluorescent layer to excite the corresponding fluorescent material, so that the corresponding first illuminating light 220 or the second illuminating light 230 is emitted, the loss of the sterilizing light 210 can be reduced, the luminous intensity of the illuminating light is ensured, and the illuminating effect is good.

At least part of the first light-transmitting member is arranged between the third fluorescent layer and the optical sterilizing member 200, which means that the third fluorescent layer can be arranged inside the light-transmitting member, so that the third fluorescent layer can be prevented from contacting with air, and the service life of the third fluorescent layer can be prolonged. The first light-transmitting piece can be made of glass or light-transmitting resin, and only the light-transmitting requirement is met.
