Detailed Description

In order that the above objects, features and advantages of the present application can be more clearly understood, the present application will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited by the specific embodiments disclosed below.

Some embodiments of the present application are described below with reference to fig. 1-11.

As shown in fig. 1 to 11, an embodiment of the present application provides a ceiling lamp 100, which includes a housing 102, a first ultraviolet lamp panel 104, a heat sink 106, a photocatalyst, and a second ultraviolet lamp panel 108. The housing 102 has an intake vent 110 and an exhaust vent 112. The intake vent 110 communicates with the exhaust vent 112. The first uv lamp panel 104 is disposed on the housing 102. The heat sink 106 is disposed within the housing 102. The heat sink 106 is in contact with the first uv lamp panel 104. The heat sink 106 is used for heat dissipation. The photocatalyst is disposed in the housing 102. The second uv lamp panel 108 is disposed in the housing 102. The second uv lamp panel 108 is used for irradiating photocatalyst.

As shown in fig. 1 to 11, a ceiling lamp 100 provided according to an embodiment of the present application includes a housing 102, a first ultraviolet lamp panel 104, a heat sink 106, a photocatalyst, and a second ultraviolet lamp panel 108. Specifically, the second uv lamp panel 108 irradiates the photocatalyst, so that the photocatalyst can generate strong oxide, and the strong oxidizing property of the strong oxide is utilized to sterilize, disinfect and remove formaldehyde from air. By utilizing the characteristics of ultraviolet rays, the first ultraviolet lamp panel 104 can sterilize and disinfect the surface of an irradiated object. That is to say, strong oxide can disinfect the disinfection and remove formaldehyde to the air, and the ultraviolet ray of first ultraviolet lamp plate 104 can disinfect the disinfection and remove formaldehyde to the object surface, and both combine to have promoted the disinfection's that disinfects purification efficiency, have shortened the disinfection's that disinfects time. Through the air exchange of air intake 110 and air outlet 112, indoor air can get into casing 102 and contact with strong oxide for strong oxide can disinfect the disinfection and remove formaldehyde to the air that gets into casing 102, thereby improves the sterile efficiency that disinfects, and then makes the sterile time that disinfects shorten. It can be understood that the ceiling lamp 100 can be arranged on the indoor ceiling, so that the irradiation range of the first ultraviolet lamp panel 104 is larger, and the sterilization and disinfection effects are better. Under first ultraviolet lamp plate 104 was in operating condition, the temperature of first ultraviolet lamp plate 104 can rise gradually. Through set up fin 106 and the contact of first ultraviolet lamp plate 104 in casing 102, be favorable to providing the heat dissipation for first ultraviolet lamp plate 104 and supplementary, avoid first ultraviolet lamp plate 104 to generate heat too high and influence its work efficiency.

As shown in fig. 1, 7, 9, and 10, in some embodiments, the ceiling lamp 100 further includes a first fan 114 and a second fan 116. It is understood that the air inlet 110 and the air outlet 112 are disposed to allow air to flow between the housing 102 and the room, and the strong oxide can sterilize and remove formaldehyde from the air entering the housing 102. The first fan 114 and the second fan 116 are respectively arranged at the air inlet 110 and the air outlet 112, and the driving force of the first fan 114 and the second fan 116 is utilized to accelerate the air circulation between the shell 102 and the room, and more non-sterile air enters the shell 102, so that the strong oxide can fully react with the non-sterile air, and the efficiency of sterilizing and removing formaldehyde is effectively improved. On one hand, under the driving action of the first fan 114 and the second fan 116, the circulation of air between the housing 102 and the room is accelerated, so that the air can enter the housing 102 more quickly to sterilize, disinfect and remove formaldehyde, thereby shortening the time of sterilizing, disinfecting and removing formaldehyde. On the other hand, under first fan 114 and the driving action of second fan 116, the air that gets into through air intake 110 can carry out heat dissipation cooling to a certain extent to second ultraviolet lamp plate 108, avoids the high temperature of second ultraviolet lamp plate 108. The first fan 114 and the second fan 116 may also be provided with filters. The filter can prevent particles and dust from entering the housing 102 through the air inlet 110 and the air outlet 112, and prevent impurities from adhering to the surface of the photocatalyst, which affects the output of the strong oxide.

As shown in fig. 9 and 10, further, the photocatalyst is uniformly attached to the heat sink 106. It can be understood that the output of the strong oxide is determined by the irradiation of the second uv lamp panel 108 on the photocatalyst. That is, the more photocatalyst the second uv lamp panel 108 irradiates, the more strong oxide is generated. That is, the photocatalyst may be uniformly coated on the surface of the heat sink 106, and the second uv lamp panel 108 may be disposed at an opposite position of the heat sink 106. Like this, second ultraviolet lamp plate 108 can fully shine photocatalyst to promote strong oxide's output, thereby promote the efficiency that the disinfection that disinfects removes formaldehyde, shorten air-purifying's time.

As shown in fig. 1 and 9, specifically, the first ultraviolet lamp panel 104 and the second ultraviolet lamp panel 108 are both LED ultraviolet lamp panels, and the LEDs are light emitting diodes. Ultraviolet rays with a wavelength shorter than 243nm can excite oxygen in air or water to generate ozone, and the ultraviolet wavelengths of the LED ultraviolet lamp panels are higher than 255nm, so that the first ultraviolet lamp panel 104 and the second ultraviolet lamp panel 108 do not normally generate ozone during normal irradiation. The increase in temperature of the first uv lamp panel 104 affects the uv wavelength. That is, too high temperature makes the wavelength of ultraviolet rays short, so that ozone is easily generated. The contact of the heat dissipation sheet 106 and the first ultraviolet lamp panel 104 can prevent the temperature of the first ultraviolet lamp panel 104 from being too high, and can effectively reduce the ozone output. In addition, the over-high temperature of the first ultraviolet lamp panel 104 may affect the luminous efficiency of the first ultraviolet lamp panel 104, and further affect the sterilization effect. Therefore, the provision of the heat sink 106 is necessary.

As shown in fig. 1, in other embodiments, the ceiling lamp 100 further includes a human body sensor 118. It is understood that the body sensor 118 is used to detect whether a person is within the detection range of the body sensor 118. That is, through the detection of the human body sensor 118, when a person enters the room from the outside, the first ultraviolet lamp panel 104 is turned off in time, so as to prevent the ultraviolet rays from damaging the human body. For example, when a person is in a room, the human body sensor 118 can detect the presence of the person, so as to control the first ultraviolet lamp panel 104 to keep the first ultraviolet lamp panel in a closed state, thereby preventing the ultraviolet lamp from damaging the human body. When the person leaves from the room, that is, the human body sensor 118 detects that the person leaves the detection range, the system starts timing, and after 15 seconds, the first ultraviolet lamp panel 104 is lighted again to restart the disinfection operation. Wherein, 15 seconds is a preset value, the preset value can also be 20 seconds, 25 seconds or 30 seconds, etc., and can be adjusted according to actual needs. The setting of human body sensor 118, when can making the people turn back suddenly, first ultraviolet lamp plate 104 can not light suddenly, and the ultraviolet ray of avoiding first ultraviolet lamp plate 104 to send causes the damage to the human body. Moreover, the setting of the human body sensor 118 can effectively avoid the first ultraviolet lamp panel 104 from frequently lighting up, thereby prolonging the service life of the first ultraviolet lamp panel 104.

As shown in fig. 6, the ceiling lamp 100 further includes a sign interface 120. It is understood that the sign interface 120 is provided on the housing 102. The sign interface 120 can be connected to an external prompting device. For example, ceiling lamp 100 is located indoorly, can set up suggestion device on the door body, and ceiling lamp 100 passes through sign interface 120 with the suggestion device and is connected. When the first ultraviolet lamp panel 104 is in a working state, the prompting device can send a prompting signal. The prompting signal can be a light signal, a text signal and the like. Taking the light signal as an example, when the first ultraviolet lamp panel 104 is working, the red light on the prompting device will light up. When the first ultraviolet lamp panel 104 stops working, the blue lamp on the prompting device lights up. People can judge whether the room is disinfected or not by turning on the red light or the blue light.

As shown in fig. 8, further, the ceiling lamp 100 further includes a synchronization interface 122. It can be understood that when the indoor sterilization effect does not reach the standard, a plurality of ceiling lamps 100 can be arranged indoors for sterilization at the same time. That is, each ceiling lamp 100 is configured with a synchronization interface 122. For example, two ceiling lamps 100 are taken as an example. The wiring of two synchronous interfaces 122 is integrated to the switch, and through the on-off operation of switch, two ceiling lamps 100 can be opened simultaneously or close simultaneously. Due to the arrangement of the synchronous interface 122, the operation steps of opening and closing the ceiling lamp 100 are optimized, the control and the maintenance are convenient, the operation is simpler, and the operation time is saved.

As shown in fig. 6, further, the ceiling lamp 100 further includes a power interface 124. It is understood that the power interface 124 is for an external power source. That is, the external power source can be accessed through the power interface 124, so as to supply power to the first ultraviolet lamp panel 104, the second ultraviolet lamp panel 108, the heat sink 106, the first fan 114, the second fan 116, the body sensor 118 and other electronic components.

As shown in fig. 8 to 11, specifically, the sign interface 120, the synchronization interface 122, and the power interface 124 are provided on the same side of the housing 102. As shown in fig. 3, fig. 3 is a left side view of the ceiling lamp 100. As shown in fig. 4, fig. 4 is a right side view of the ceiling lamp 100. As shown in fig. 5, fig. 5 is a top view of the ceiling lamp 100. As shown in fig. 6, fig. 6 is a bottom view of the ceiling lamp 100. In one aspect, the plurality of ports are disposed on the same side of the housing 102 to facilitate processing and manufacturing of the housing 102. On the other hand, when the interfaces arranged on the same side are used for designing the wiring, the indoor space can be saved, the length of the wiring is saved, and therefore the cost is saved.

As shown in fig. 11, in some embodiments, the ceiling lamp 100 further includes a cover 126. It will be appreciated that the cover 126 is coupled to the housing 102, as shown in FIG. 2, such that the cover 126 can close the housing 102. On one hand, the connection between the cover 126 and the housing 102 can effectively prevent impurities such as mosquitoes and particles from entering the housing 102 and adhering to the surface of the photocatalyst, thereby ensuring that the photocatalyst can normally produce strong oxide. On the other hand, the cover 126 is arranged, so that the air flows more stably when passing through the air inlet 110 and the air outlet 112, the exchange of the air between the shell 102 and the room is promoted, and the effects of sterilization, disinfection and formaldehyde removal are higher.

As shown in fig. 10 and 11, the second uv lamp panel 108 is further fixed to the inside of the cover 126. It can be understood that the second uv lamp panel 108 is disposed on a sidewall of a space formed by the housing 102 and the cover 126. That is, the irradiation range of the second uv lamp panel 108 is larger. That is to say, can set up second ultraviolet lamp plate 108 on the opposition plane at fin 106 central point and put the place, ensure that the second ultraviolet ray can be as many as possible shine photocatalyst to enlarge the output of strong oxide in the unit interval, and then make more strong oxides can disinfect the disinfection and remove formaldehyde to the air, shorten the time of disinfecting and removing formaldehyde more closely.

Further, it can be understood that, due to the different sizes of the heat sink 106 and the second ultraviolet lamp panel 108, when the second ultraviolet lamp panel 108 irradiates the photocatalyst on the surface of the heat sink 106, the photocatalyst on the corner of the heat sink 106 cannot be effectively irradiated. Therefore, a plurality of second uv lamp panels 108 can be arranged to irradiate the photocatalyst. That is, as necessary, a plurality of second ultraviolet lamp panels 108 may be provided at intervals inside the cover 126, and the plurality of second ultraviolet lamp panels 108 may be cut at different angles when the photocatalyst is irradiated onto the surface of the heat sink 106, thereby expanding the irradiation range of the second ultraviolet lamp panels 108. That is to say, the setting of a plurality of second ultraviolet lamp boards 108 through the irradiation of multi-angle for the photocatalyst in the corner also can produce strong oxide, thereby produces more strong oxide, shortens the time of disinfecting and removing formaldehyde.

As shown in fig. 1 to 11, a ceiling lamp 100 according to an embodiment of the present application includes a housing 102, a first ultraviolet lamp panel 104, a heat sink 106, a second ultraviolet lamp panel 108, a first fan 114, a second fan 116, a human body sensor 118, a sign interface 120, a synchronization interface 122, and a power interface 124. The housing 102 has an intake vent 110 and an exhaust vent 112.

As shown in fig. 9 to 11, in the embodiment of the present application, the photocatalyst is irradiated by the second ultraviolet lamp panel 108, so that the photocatalyst can generate strong oxide, and the air entering the housing 102 is sterilized and disinfected to remove formaldehyde by using the strong oxidizing property of the strong oxide. As shown in fig. 1 and 7, the first ultraviolet lamp panel 104 utilizes the characteristics of ultraviolet rays to sterilize and disinfect the surface of an object irradiated indoors. The two sterilization and disinfection modes are combined, so that the sterilization and disinfection efficiency is higher, and the sterilization and disinfection time can be effectively shortened.

As shown in fig. 7 and 9, the heat sink 106 is in contact with the first ultraviolet lamp panel 104, so that the first ultraviolet lamp panel 104 can be effectively prevented from being too high. On the other hand, the ultraviolet rays are prevented from being affected by temperature, and the wavelength becomes short, and ozone is prevented from being generated. On the other hand, the luminous efficiency of first ultraviolet lamp panel 104 is prevented from reducing, influences the efficiency and the time of disinfecting and sterilizing.

As shown in fig. 7 and 10, the first fan 114 sucks non-sterilized air in the room into the housing 102 through the air outlet 112 for sterilization and disinfection, and the second fan 116 discharges the sterilized air into the room through the air outlet 112 to maintain the balance inside the ceiling lamp 100, so as to accelerate the circulation of air between the housing 102 and the ceiling lamp 100, improve the purification efficiency, and shorten the purification time. Through the air that air intake 110 got into, under the drive effect of first fan 114 and second fan 116, can play the effect of cooling to a certain extent to second ultraviolet lamp plate 108.

The specific embodiment has the following beneficial effects:

1) the first ultraviolet lamp panel 104 sterilizes and disinfects the surface of an indoor object, the second ultraviolet lamp panel 108 irradiates a photocatalyst to generate a strong oxide, and the strong oxide sterilizes and disinfects indoor air to remove formaldehyde. The two modes are combined to improve the efficiency of sterilization and disinfection and shorten the time of sterilization and disinfection.

2) The heat dissipation fin 106 is used for dissipating heat of the first ultraviolet lamp panel 104, and the air passing through the air inlet 110 is used for dissipating heat of the second ultraviolet lamp panel 108, so that the first ultraviolet lamp panel 104 and the second ultraviolet lamp panel 108 are prevented from being too high in temperature. On the one hand, the ultraviolet wavelength shortening caused by the temperature rise can be effectively prevented, and the ozone output is reduced to a certain extent. On the other hand, the luminous efficiency of the first ultraviolet lamp panel 104 and the second ultraviolet lamp panel 108 is prevented from being reduced, so that the efficiency of sterilization and disinfection is not reduced.
