Description

Technical Field

[0001] The invention relates to the technical field of LED indoor lighting fixtures, and in particular to a sterilization, mosquito-killing and air-purifying LED lamp and a control method thereof. Background Art

[0002] LED indoor lighting fixtures are commonly used for lighting in indoor places such as classrooms, hospitals, offices, workshops, etc. They can be embedded in the ceiling for installation, or suspended under the ceiling or fixed on the ceiling or wall surface for installation. They usually have a single lighting function.

[0003] Ultraviolet germicidal lamps can emit high-dose ultraviolet rays in a specific band, destroying the DNA or RNA of bacteria, viruses and other microorganisms and then killing cells, playing a role in sterilization and disinfection. They are widely used in hospitals, schools, nurseries, cinemas, buses, offices and other places for disinfection and sterilization. However, when existing ultraviolet lamps are used for disinfection, due to the photochemical reaction with oxygen and their own characteristics, the radiation illumination of ultraviolet lamps will be greatly attenuated as the irradiation distance increases. The general sterilization distance is within 1m, and the radiation dose and power consumption are very large. At the same time, high doses of ultraviolet rays will also kill human cells. Therefore, when using ultraviolet lamps for disinfection, they cannot directly irradiate human skin and eyes. People need to leave during disinfection, and real-time disinfection cannot be carried out in spaces where people are active. For viruses and bacteria such as the new coronavirus that spread in the air through "aerosols", real-time and uninterrupted large-scale disinfection and purification of the air in crowded and enclosed places can greatly reduce the risk of virus and bacteria transmission, which is of great significance.

[0004] Air purifiers are mainly composed of motors, fans, air filters and other systems. The working principle is: the motor and fan in the machine circulate the indoor air, and the polluted air passes through the air filter in the machine to remove or absorb various pollutants, thus achieving the purpose of cleaning and purifying the air. Air purifiers are usually placed on the ground, but when used in kindergartens and classrooms, they can be touched by children. Due to the curiosity of young children and their lack of awareness of danger, there are certain safety hazards.

[0005] In the patent document with Chinese patent application number 201611100454.1 and publication date 2018.06.15, a LED lighting fixture for sterilization and mosquito repellent is disclosed, including a lampshade, a base, an LED lamp holder and a heat dissipation pipe, the base is fixedly connected to the bottom plate by a support column, the surface of the support column is inlaid with a control panel, the lampshade is fixedly connected to the bottom plate by a lampshade support rod, the LED lamp holder is installed on the upper surface of the bottom plate, the electric mosquito coil body is composed of an electric mosquito coil installation plate, an outer shell, an electric heating wire and an air diffusion pipe, the top of the outer shell is provided with an air diffusion pipe, and the inner part of the outer shell is provided with an electric mosquito coil installation plate and an electric heating wire. The ultraviolet sterilization lamp provided in the invention can sterilize and disinfect the bacteria in the air by turning on the sterilization switch according to the needs of the user, and the electric mosquito coil body is provided, so that mosquitoes can be killed indoors when there are many mosquitoes in summer, and it is convenient to use, and the heat emitted from the heat dissipation pipe is used for the electric mosquito coil body, which is energy-saving and environmentally friendly, and saves resources.

[0006] However, the lamp of the invention uses electric mosquito coils to repel mosquitoes. The efficacy is good when it is first used, but after 4 to 5 hours, the insecticide evaporates completely, the efficacy deteriorates, and the mosquito repellent effect weakens. If the electric mosquito coil selected by the user is not good, the odor is too strong and it is not suitable for people with allergies. In addition, the lamp only sterilizes the indoor environment through ultraviolet germicidal lamps, and cannot achieve air purification. The sterilization is only achieved through natural air flow, so the sterilization efficiency is low, and the sterilization effect is poor for locations far away from the lamp. During sterilization, the user cannot get close to the lamp, and the ultraviolet germicidal lamp leaks, causing harm to the human body. Summary of the invention

[0007] The purpose of the present invention is to provide a sterilization and mosquito-killing air purification LED lamp and a control method, which has a general lighting function and can sterilize and disinfect the air in real time.

[0013] b) After the test is completed, the sterilization component and the fan component are controlled according to the number of microorganisms and the air quality.

[0014] c) When the number of microorganisms detected exceeds a first threshold and the air quality is lower than a second threshold, the sterilization component increases the irradiation efficiency of the ultraviolet lamp and speeds up the fan to accelerate sterilization and air purification.

[0015] d) When the number of microorganisms detected is lower than a first threshold and the air quality is higher than a second threshold, the sterilization component reduces the irradiation efficiency of the ultraviolet lamp and reduces the fan speed.

[0016] e) When the number of microorganisms detected exceeds a first threshold and the air quality is higher than a second threshold, the sterilization component increases the irradiation efficiency of the ultraviolet lamp and reduces the fan speed.

[0021] Furthermore, the air outlet is arranged at the top of the lampshade, and the filter net is detachably connected to the air outlet. In this way, the air outlet is arranged at the top of the lampshade, and the purified and sterilized air is discharged from the top of the lampshade. This can be used for suspended lamps, and the indoor air can be purified and sterilized through the top air outlet. The filter net is detachably arranged on the air outlet, so that the filter net can be removed from the top of the lamp for cleaning.

[0022] Furthermore, the air outlet is arranged at the bottom of the lampshade, the top of the lampshade is provided with a first air outlet, a first air flow channel is formed between the first air outlet and the air outlet, a removable top cover is provided on the first air flow channel above the first air outlet, a removable end cover is provided on the top cover, a second air outlet is provided on the base, the second air outlet is communicated with the air outlet, and the filter is detachably connected to the second air outlet.

Figures 9 to 11 As shown, the filter 45 is detachably connected to the lampshade 1 through the upper buckle 6. This structure facilitates the installation and removal of the grid plate 23 and the filter 45 through the detachable connection, and facilitates the cleaning, washing and replacement of the grid plate 23 and the filter 45.

[0057] In this example, the mosquito killing component is located on the periphery of the lighting lamp.

[0058] like Figure 2 and Figure 7 As shown, the sterilization component 4 includes an ultraviolet lamp 41, a radiator 42, a fan assembly, a filter 45 and a guide seat 46.

[0059] like Figure 8 As shown, the ultraviolet lamp 41 includes an inner ultraviolet lamp 411 and an outer ultraviolet lamp 412. A ventilation hole is provided on the lamp panel of the inner ultraviolet lamp 411, and the ultraviolet lamp 41 is an ultraviolet LED lamp (such as a UVC LED or a UVB LED).

[0060] like Figure 8As shown, the radiator 42 includes a radiator base 421 and a heat sink 426. The radiator base 42 includes an inner heat sink 421 and an outer heat sink 422. The inner heat sink 421 is provided with a ventilation channel 425 which runs through from top to bottom. The outer heat sink 422 is arranged at the periphery of the inner heat sink 421. The bottom surface of the outer heat sink 422 is higher than the bottom surface of the inner heat sink 421. An inner wind shield plate 424 extends downward from the periphery of the inner heat sink 421. A first air inlet groove is formed between the inner wind shield plate 424 and the guide seat 46. The heat sink 426 is arranged on the outer heat sink 422. The interface of the heat sink 426 is annular. The upper end of the heat sink 426 is connected to the lampshade 1. The inner ultraviolet lamp 411 is installed at the bottom of the inner heat sink 421, and the outer ultraviolet lamp 412 is installed at the bottom of the outer heat sink 422. The ventilation channel 425 is connected to the ventilation hole and the air outlet 102.

[0061] like Figure 8 As shown, the fan assembly includes a drive motor 43 and a fan 44. The drive motor 43 is installed on the middle part of the inner heat sink 421, and the fan 44 is installed on the output shaft of the drive motor.

[0062] This structure, by setting up internal and external ultraviolet lamps, sterilizes viruses, bacteria and other microorganisms contained in the air in the lampshade in sections and at multiple levels, and kills viruses, bacteria and other microorganisms thoroughly, further improving the sterilization effect. The internal and external ultraviolet lamps are dispersedly dissipated by setting up internal and external heat sinks, and the heat sink area is increased by using heat sinks to improve the heat dissipation effect. At the same time, the heat is transferred to the lampshade through the heat sink, and the lampshade is used to partially dissipate the heat, which improves the heat dissipation effect as a whole and increases the service life of the ultraviolet lamp. In the above structure, the ventilation holes and ventilation channels facilitate the air in the lampshade to flow into the filter net. At the same time, when the air passes through the heat dissipation channel, the wind can take away the heat of the internal heat sink, thereby improving the heat dissipation effect.

[0063] like Figures 9 to 11 As shown, the filter screen 45 comprises a bracket 451 and a filter screen body 452. The bracket 451 is annular, and a notch 4511 is provided on the outer wall of the bracket 451 (in Fig.10As shown in FIG. 4 , an elastic upper buckle 6 is provided on the notch 4511, and the upper buckle 6 includes an upper elastic arm 61, an upper protrusion 62 and an upper toggle protrusion 63. The lower end of the upper elastic arm 61 is connected to the lower end of the notch 4511, and a gap is formed between the upper elastic arm 61 and the side wall of the notch 4511. The upper protrusion 62 is provided on the outer side of the upper elastic arm 61 and protrudes out of the bracket 451. The toggle protrusion 63 is provided on the upper end of the upper elastic arm 61. A card slot 4512 is provided on the inner wall of the bracket 451, and the filter body 452 is clamped on the card slot 4512. When the filter needs to be installed, the filter 45 is placed at the air outlet and then pressed downward. The upper elastic arm 61 is elastically deformed under the squeezing action of the upper protrusion 62 and the edge of the air outlet. When the upper protrusion 62 moves to below the bottom surface of the lampshade top plate, the upper elastic arm is reset and the upper protrusion is snapped into the bottom of the lampshade light board to achieve the installation of the filter 45. If the filter 45 needs to be removed, the upper elastic arm 61 is elastically deformed by the upper toggle protrusion 63 to separate the upper protrusion 62 from the lampshade light board and the filter can be taken out. Therefore, quick installation and disassembly can be achieved, which is convenient for cleaning and replacement of the filter.

[0064] A heat sink 42 is provided above the guide seat 46. Figure 4 As shown, the guide seat 46 includes a guide plate 461 and a guide base 462. The guide base 462 is arranged on the cover plate 34, and the guide plate 461 is arranged on the guide base 462. There are more than two guide plates, and an air guide groove is formed between adjacent guide plates. The shape of the guide plate 461 extends upward in a stepped manner from the edge of the guide base 462 to the center of the guide base 462. The guide plate extends outward in an arc shape from the center of the guide base so that all the guide plates form a vortex shape.

[0065] like Figure 2 and Figure 7 As shown, a downwardly extending outer wind shield 13 is provided on the outer periphery of the outer heat sink 422 on the lampshade, and a second air inlet slot is formed below the outer wind shield. This structure changes the flow path and path length of the airflow through the inner and outer wind shields, allowing the ultraviolet lamp to act on microorganisms such as viruses and bacteria for a longer time, thereby further improving the sterilization effect.

[0066] like Figure 7 As shown, a shielding cover 12 is provided between the inner wind shield plate and the outer wind shield plate, a third air inlet slot is formed above the shielding cover, and wind slots are formed between the inner wind shield plate and the shielding cover and between the outer wind shield plate and the shielding cover respectively. Since ultraviolet rays have certain side effects on the human body, the shielding cover can reduce radiation and reduce harm to the human body.

[0067] A microorganism detection device is installed in the lampshade, and the microorganism detection device includes a microorganism sensor and a controller. The controller controls the sterilization component. An air quality detection device is installed on the lampshade, and the air quality detection device includes an air quality sensor and a first controller. The air quality sensor and the microorganism sensor are provided in two groups, one group is installed on the outside of the air inlet, used to detect the indoor air quality and the number of microorganisms, and the other group is arranged on the inside of the air outlet, used to detect the air quality and the number of microorganisms after sterilization and purification. In addition, the air quality detection device and the microorganism detection device can also be installed in the indoor space where the sterilization and mosquito-killing purification LED lamp is installed, and the detected data is transmitted to the microcontroller unit MCU of the sterilization mosquito-attracting lamp through wireless or other transmission methods. The microorganism detection device and the control quality detection device are existing devices.

[0068] In another embodiment, an ultraviolet radiation illuminometer for detecting the ultraviolet radiation illuminance is arranged in the lampshade near the ultraviolet lamp, so that the radiation illuminance of the ultraviolet lamp can be detected in real time to ensure the adjustment accuracy of the ultraviolet lamp.

[0069] Of course, in the present invention, the illuminating lamp, the mosquito-killing component and the sterilizing component can be turned on simultaneously or separately. In the present invention, the illuminating lamp, the mosquito-killing component and the sterilizing component are integrated together to form a lamp with the comprehensive functions of illuminating, mosquito-killing and sterilizing.

The lamp holder assembly includes a lamp holder 11 and a mosquito-killing assembly 2.

[0072] like Fig.13 and Figure 3 As shown, the lamp holder 11 comprises a frame 111 and a base 112. In this embodiment, the frame 111 and the base 112 are both rectangular, but can also be other shapes.

The top plate 211, the lamp board 212 and the connecting plate 213 form an inverted U shape to form a cavity 200 in the base 21. The lower end of the cavity 200 is an opening 201. In this way, air will enter the lampshade 1 from the opening 201 through the cavity 200 and the air inlet 2111. In the process of killing mosquitoes, under the action of wind flow, , more mosquitoes can be attracted to the electric grid board 23, which can further improve the effect of killing mosquitoes; the lamp board 212 is connected to the lampshade 1 by screws 2121, and the lower end of the lamp board 212 is connected to the frame as a whole. A mosquito attracting lamp 22 is provided in the cavity 200 on the lamp board 212, and the limiting plate 214 is provided at the bottom end of the connecting plate 213 and is pressed and fixed with the base 24 to fix the light guide plate 32, the diffusion plate 33 and the cover plate 34 of the lighting lamp 3, and the LED light source is arranged on the outside of the light guide plate 32, and the limiting plate 214 and the base 112 are connected to the connecting groove by fixing screws 25 for fixing.

[0077] like Figure 1 and Fig.13 As shown, the lampshade 1 has a cavity 101 therein, a first air outlet 101 is provided at the middle of the top of the lampshade 1 , and an air outlet 102 is provided at the bottom of the lampshade 1 .

[0080] The above structure, through the arrangement of the top cover 7 and the second air outlet 1021, allows air to flow out from the bottom of the lampshade 1. Therefore, in this embodiment, the germicidal and mosquito-killing air purification lamp can be embedded and installed on the ceiling and can be used for negative pressure wards.

[0081] like Fig.12 As shown, the grid plate 23 is detachably connected to the base 21 through the lower buckle 231, as shown in FIG. Figures 9 to 11 As shown, the filter 45 is detachably connected to the first air outlet and the second air outlet of the lampshade 1 through the upper buckle 6. This structure facilitates the installation and removal of the grid plate 23 and the filter 45 through the detachable connection, and facilitates the cleaning, washing and replacement of the grid plate 23 and the filter 45.

[0082] In this example, the mosquito killing component is located on the periphery of the lighting lamp.

[0083] like Figure 2 and Figure 7 As shown, the sterilization component 4 includes an ultraviolet lamp 41, a radiator 42, a fan assembly, a filter 45 and a guide seat 46.

[0084] like Figure 8 As shown, the ultraviolet lamp 41 includes an inner ultraviolet lamp 411 and an outer ultraviolet lamp 412. The ultraviolet lamp 41 is a UVC LED or a UVB LED, and a ventilation hole is provided on the lamp panel of the inner ultraviolet lamp 411.

[0085] like Figure 8As shown, the radiator 42 includes a radiator base 421 and a heat sink 426. The radiator base 42 includes an inner heat sink 421 and an outer heat sink 422. The inner heat sink 421 is provided with a ventilation channel 425 which runs through from top to bottom. The outer heat sink 422 is arranged at the periphery of the inner heat sink 421. The bottom surface of the outer heat sink 422 is higher than the bottom surface of the inner heat sink 421. An inner wind shield plate 424 extends downward from the periphery of the inner heat sink 421. A first air inlet groove is formed between the inner wind shield plate 424 and the guide seat 46. The heat sink 426 is arranged on the outer heat sink 422. The interface of the heat sink 426 is annular. The upper end of the heat sink 426 is connected to the lampshade 1. The inner ultraviolet lamp 411 is installed at the bottom of the inner heat sink 421, and the outer ultraviolet lamp 412 is installed at the bottom of the outer heat sink 422. The ventilation channel 425 is connected to the ventilation hole and the air outlet 102.

[0086] like Figure 8 As shown, the fan assembly includes a drive motor 43 and a fan 44.

The fan 44 is located in the space between the inner heat sink 421 and the filter 45.

[0087] This structure, by setting up internal and external ultraviolet lamps, sterilizes viruses, bacteria and other microorganisms contained in the air in the lampshade in sections and at multiple levels, thoroughly kills viruses and bacteria, and further improves the sterilization effect. The internal and external ultraviolet lamps are dispersedly dissipated by setting up internal and external heat sinks, and the heat sink area is increased to improve the heat dissipation effect. At the same time, the heat is transferred to the lampshade through the heat sink, and the lampshade is used to partially dissipate the heat, which improves the heat dissipation effect as a whole and increases the service life of the ultraviolet lamp. In the above structure, the ventilation holes and ventilation channels facilitate the air in the lampshade to flow into the filter net. At the same time, when the air passes through the heat dissipation channel, the wind can take away the heat of the internal heat sink, thereby improving the heat dissipation effect.

[0088] like Figures 9 to 11 As shown, the filter screen 45 comprises a bracket 451 and a filter screen body 452. The bracket 451 is annular, and a notch 4511 is provided on the outer wall of the bracket 451 (in Fig.10As shown in FIG. 4 , an elastic upper buckle 6 is provided on the notch 4511, and the upper buckle 6 includes an upper elastic arm 61, an upper protrusion 62 and an upper toggle protrusion 63.

The upper protrusion 62 is provided on the outer side of the upper elastic arm 61 and protrudes out of the bracket 451. The toggle protrusion 63 is provided on the upper end of the upper elastic arm 61. A card slot 4512 is provided on the inner wall of the bracket 451, and the filter body 452 is clamped on the card slot 4512. When the filter needs to be installed, the filter 45 is placed at the air outlet and then pressed downward. The upper elastic arm 61 is elastically deformed under the squeezing action of the upper protrusion 62 and the edge of the air outlet. When the upper protrusion 62 moves to below the bottom surface of the lampshade top plate, the upper elastic arm is reset and the upper protrusion is snapped into the bottom of the lampshade light board to achieve the installation of the filter 45. If the filter 45 needs to be removed, the upper elastic arm 61 is elastically deformed by the upper toggle protrusion 63 to separate the upper protrusion 62 from the lampshade light board and the filter can be taken out. Therefore, quick installation and disassembly can be achieved, which is convenient for cleaning and replacement of the filter.

[0089] A radiator 42 is provided above the guide seat 46. Figure 4 As shown, the guide seat 46 includes a guide plate 461 and a guide base 462. The guide base 462 is arranged on the cover plate 34, and the guide plate 461 is arranged on the guide base 462.

The shape of the guide plate 461 extends upward in a stepped manner from the edge of the guide base 462 to the center of the guide base 462. The guide plate extends outward in an arc shape from the center of the guide base so that all the guide plates form a vortex shape.

[0090] like Figure 3 and Figure 7 As shown, a downwardly extending outer wind shield 13 is provided on the outer periphery of the outer heat sink 422 on the lampshade, and a second air inlet slot is formed below the outer wind shield. This structure changes the flow path and path length of the airflow through the inner and outer wind shields, allowing the ultraviolet lamp to act on viruses and bacteria for a longer time, thereby further improving the sterilization effect.

[0091] like Figure 7 As shown, a shielding cover 12 is provided between the inner wind shield plate and the outer wind shield plate, a third air inlet slot is formed above the shielding cover, and wind slots are formed between the inner wind shield plate and the shielding cover and between the outer wind shield plate and the shielding cover respectively. Since ultraviolet rays have certain side effects on the human body, the shielding cover can reduce radiation and reduce harm to the human body.

[0092] A microorganism detection device is installed in the lampshade, and the microorganism detection device includes a microorganism sensor and a controller. The controller controls the sterilization component. An air quality detection device is installed on the lampshade, and the air quality detection device includes an air quality sensor and a first controller. The air quality sensor and the microorganism sensor are provided in two groups, one group is installed on the outside of the air inlet, used to detect the indoor air quality and the number of microorganisms, and the other group is arranged on the inside of the air outlet, used to detect the air quality and the number of microorganisms after sterilization and purification. In addition, the air quality detection device and the microorganism detection device can also be installed in the indoor space where the sterilization and mosquito-killing purification LED lamp is installed, and the detected data is transmitted to the microcontroller unit MCU of the sterilization mosquito-attracting lamp through wireless or other transmission methods. The microorganism detection device and the control quality detection device are existing devices.

[0093] In another embodiment, an ultraviolet radiation illuminometer for detecting the ultraviolet radiation illuminance is arranged in the lampshade near the ultraviolet lamp, so that the radiation illuminance of the ultraviolet lamp can be detected in real time to ensure the adjustment accuracy of the ultraviolet lamp.

[0094] Of course, in the present invention, the illuminating lamp, the mosquito-killing component and the sterilizing component can be turned on simultaneously or separately. In the present invention, the illuminating lamp, the mosquito-killing component and the sterilizing component are integrated together to form a lamp with the comprehensive functions of illuminating, mosquito-killing and sterilizing.

[0095] Example 3

[0096] like Fig.17 As shown, the control method of the above-mentioned sterilization and mosquito-killing air purification LED lamp is:

[0097] The specific steps include:

[0098] a) When the lighting lamp is in use, the microbial detection device starts to detect the number of microorganisms in the air, and the air quality detection device starts to detect the air quality. The working principle of the microbial detection device to detect the number of microorganisms and the working principle of the air quality detection device to detect the air quality are existing technologies.

[0099] b) After the test is completed, the sterilization component and the fan component are controlled according to the number of microorganisms and the air quality.

[0100] c) When the number of microorganisms detected exceeds a first threshold, which is a preset value of the number of microorganisms, and the air quality is lower than a second threshold, which is a preset value of the air quality, the sterilization component increases the irradiation efficiency of the ultraviolet lamp and increases the speed of the fan to accelerate sterilization and air purification. Specifically, the speeds of the ultraviolet lamp and the fan are adjusted in a step-by-step manner according to the preset detected number of microorganisms, air quality, and the corresponding current value of the ultraviolet lamp and the speed of the fan. It can also be adjusted by setting a fixed ultraviolet lamp current value when the number of microorganisms exceeds the first threshold and another fixed ultraviolet lamp current when the number of microorganisms is lower than the first threshold; by setting a fixed fan speed when the air quality exceeds the second threshold and another fixed fan speed when the air quality is lower than the second threshold.

[0101] d) When the number of microorganisms detected is lower than a first threshold and the air quality is higher than a second threshold, the sterilization component reduces the irradiation efficiency of the ultraviolet lamp and reduces the speed of the fan.

[0102] e) When the number of microorganisms detected exceeds a first threshold and the air quality is higher than a second threshold, the sterilization component increases the irradiation efficiency of the ultraviolet lamp and reduces the fan speed.

[0103] f) When the number of microorganisms detected is lower than a first threshold and the air quality is lower than a second threshold, the sterilization component reduces the irradiation efficiency of the ultraviolet lamp and increases the fan speed.

[0104] e) The mosquito killing component turns on the mosquito attractant lamp and kills the mosquitoes through the electric grid.

[0105] In another embodiment, an ultraviolet radiation illuminance meter is arranged in the lampshade. The ultraviolet radiation illuminance meter detects the radiation illuminance value of the ultraviolet lamp in real time when the ultraviolet lamp is turned on. If the current radiation illuminance value is within the set radiation illuminance value range, if it is not within the range, the current value of the ultraviolet lamp is adjusted again so that the current value reaches the target value. If the target value still cannot be reached after multiple adjustments, it is prompted that the ultraviolet lamp needs to be replaced, such as in step c) "when the number of microorganisms detected exceeds a first threshold, the first threshold is a preset microorganism number value, and the air quality is lower than a second threshold, the second threshold is a preset air quality value, and the sterilization component increases the irradiation efficiency of the ultraviolet lamp". After that, the radiation illuminance value of the ultraviolet lamp is measured in real time. If the radiation illuminance value is not within the radiation illuminance value corresponding to the fixed ultraviolet current value, the current value of the ultraviolet lamp is adjusted again to a fixed ultraviolet lamp current value. If it still cannot meet the requirements after multiple (for example, three) adjustments, a prompt is given; this setting can improve the adjustment accuracy of the ultraviolet lamp.
