Description

Intelligent full-time germicidal lighting group

The present invention relates to a germicidal lighting group, in particular to an intelligent full-time germicidal lighting group that can be installed in an existing light steel frame ceiling.

Ultraviolet light has a great disinfection and sterilization effect on harmful bacteria and viruses. The principle of disinfection and sterilization is that when bacteria and viruses are irradiated with ultraviolet light, the structure of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) at the core of their life will be directly destroyed by ultraviolet light, so that the proteins needed for survival or reproduction Cannot form, causing bacteria and viruses to die immediately or lose their ability to reproduce. Generally speaking, this disinfection and sterilization effect can be achieved within 1 to 2 seconds of ultraviolet light irradiation. However, things are yin and yang. Ultraviolet light can eliminate bacteria and viruses that are harmful to the human body, and also cause harm to the human body. For example, under the exposure of ultraviolet light, the human skin will gradually produce melanin, and if the exposure time and frequency continue to increase, it may lead to the occurrence of melanoma; ultraviolet light will cause damage to the lens of the eye and around the eye, which is easy to cause eye damage. Skin cancer around the body, deterioration and degeneration of the retina, and severe cases are more likely to cause damage to the transparency of the lens and lead to blindness. Therefore, special attention should be paid to safety when using ultraviolet light to disinfect and sterilize the surrounding environment.

On the other hand, due to the recent outbreak of new coronary pneumonia, people are thinking about how to maintain the quality of indoor air, especially how to disinfect and sterilize indoors that are almost closed.

Schematic diagram of the appearance of another smart full-time germicidal lighting group.

The present invention will be described more specifically by referring to the following embodiments.

See Figures 1 to 3. 1 is a schematic diagram of the appearance of an intelligent full-time germicidal lighting lamp group 1 according to an embodiment of the present invention, FIG. 2 is a schematic diagram of the intelligent full-time germicidal lighting lamp group 1 viewed downward along the section AA′ in FIG. 1 , and FIG. 3 It is a schematic diagram of the intelligent full-time germicidal lighting group 1 viewed from the top along the section AA' in FIG. 1 . According to the present invention, the intelligent full-time germicidal lighting set 1 includes an outer casing 10 , a plurality of ultraviolet germicidal light sources 20 , an airflow driving module 30 and a control module 40 . The structure, function and interaction with other technical elements of the aforementioned technical elements will be described in detail below.

The outer casing 10 is formed by an air duct portion 11 and an air inlet portion 12 and an air outlet portion 13 on both sides thereof. In this embodiment, when viewed from the bottom of the outer casing 10, its shape is a square with a side length of about 60 cm points, close to the size of the calcium silicate board of the light steel frame ceiling. Therefore, the intelligent full-time germicidal lighting group 1 can replace a calcium silicate board and be installed in the existing light steel frame structure without additional fixing facilities. The cross-section of the air duct portion 11 is rectangular and is a flat tubular structure, and a lighting area 111 is formed on the lower side of the outer side. Wind Zone 131. The lighting area 111 is provided with at least one lighting lamp 112 for indoor lighting. Here are 9 groups of LED strips. In other embodiments, the number of the lighting lamps 112 is not limited to 9 groups, and there may be more or only one group; tube), etc., which are not limited in the present invention.

The air inlet area 121 has at least one air inlet 122 , which is seven in this embodiment. In practice, the number of air inlets 122 is set according to actual needs, and is not limited to 7; the shape of air inlets 122 is not limited to the rectangle as shown in FIG. Regular line shape. The at least one air inlet 122 is provided with a filter screen (inside the air inlet 122, which is indicated by a horizontal diagonal line) to filter the floating dust in the outside air. Similarly, the air outlet area 131 has at least one air outlet 132 (the number of air outlets 132 is set according to actual needs, and in this embodiment, there are also seven, and the shape is also not limited like the air inlet 122). The air outlet 132 is provided with a filter screen (inside the air outlet 132 , which is indicated by a horizontal oblique line) to filter the floating dust in the air flowing through the inside of the outer casing 10 . Here, when the intelligent full-time germicidal lighting lamp group 1 is activated, it will be diverted to allow external air to flow into the air duct portion 11 for disinfection and sterilization. The direction of air circulation is from the air inlet 122 in FIG. 1, entering the air inlet 12 in the direction of the dotted arrow frame, passing through the air duct 11 and then to the air outlet 13, and leaving the smart model from the air outlet 132 in the direction of the blank arrow frame. Full-time germicidal lighting group 1. Since both the air inlet 122 and the air outlet 132 are provided with filters, the dust in the air circulating out of the intelligent full-time germicidal lighting set 1 will be greatly reduced.

A feature of the present invention is that the direction of the air inlet 122 and the direction of the air outlet 132 are not necessarily parallel to the lighting area 111 . Expressed in terms of technical characteristics, the normal direction of at least one air inlet 122 (represented by the solid arrow in FIG. 1 ) and the normal direction of at least one air outlet 132 (represented by the arrow dotted line in FIG. 1 ) are different from each other. The included angle between the normal direction of the illumination area 111 (represented by the dashed arrow in FIG. 1 ) is not greater than a first angle. the first An angle is within 10 degrees. That is to say, when the first angle is 0 degrees, the normal direction of the air inlet 122 , the normal direction of the air outlet 132 and the normal direction of the lighting area 111 are parallel (as shown in FIG. 1 ), and the airflow enters from the air inlet 122 The rear turning into the air duct portion 11 requires a turn close to 90 degrees, and the turning from the air duct portion 11 out of the air outlet 132 also requires a turn close to 90 degrees, which is likely to cause wind shear noise. If the first angle is 10 degrees, the air turn only needs to be 80 degrees, and the noise will be reduced. However, the first angle should not be set too large, which will increase the area of the air inlet part 12 and the air outlet part 13 and reduce the length of the air duct part 11 . Since the air duct part 11 is a space for installing the disinfection and sterilization equipment, the reduction in its length means the weakening of the disinfection and sterilization ability.

In addition, in order to reduce the noise caused by wind shear, the air inlet portion 12 can form a curved arc section 123, and the curved arc section 123 is connected to the air duct portion 11 and at least one air inlet 122 to reduce the noise when the airflow passes through. Similarly, the air outlet portion 13 may also form a curved arc section 133, and the curved arc section 133 is connected to the air duct portion 11 and at least one air outlet 132, so as to reduce the noise when the airflow passes through.

The ultraviolet sterilization light source 20 is installed in the air duct portion 11 , and its position is shown in FIG. 2 . In this embodiment, four ultraviolet germicidal light sources 20 are used, and they are installed at the bottom of the air duct portion 11 (so not shown in FIG. 3 ). According to the present invention, the number of ultraviolet germicidal light sources 20 is not limited, and the forms may be, but are not limited to, UV light emitting diode strips, strip-shaped UV germicidal lamps and annular UV germicidal lamps. In this embodiment, a strip-shaped ultraviolet germicidal lamp is used as an example for description. When the air flows in the direction indicated by the dotted arrow box in FIG. 2 , the activated ultraviolet sterilization light source 20 will sterilize it. At the same time, because the ultraviolet light only diffuses in the air duct portion 11 (outer casing 10 ), it will not harm the people outside (the airtight room).

The airflow driving module 30 can be installed in any part of the air duct part 11 , the air inlet part 12 or the air outlet part 13 , as long as the design size permits. In the present embodiment, the airflow driving module 30 is installed in the air duct portion 11 and is located on the upper wind of the ultraviolet sterilization light source 20 . In other embodiments, the arrangement of the airflow driving module 30 and the ultraviolet sterilization light source 20 can be changed differently. 4 to illustrate, in another embodiment, the airflow drive module 30 is located in the air duct portion 11, and at the downwind of the ultraviolet sterilization light source 20 (the ultraviolet sterilization light source 20 is close to the side of the air outlet 13, the airflow is The driving module 30 is located on a side close to the air inlet 12). Illustrated with Figure 5, In yet another embodiment, the airflow driving module 30 is located in the air inlet portion 12 . Since it does not occupy any space, the number of ultraviolet germicidal light sources 20 in the air duct portion 11 can be increased (seven). Referring to FIG. 6 , in yet another embodiment, the airflow driving module 30 is located in the air outlet 13 , and the number of ultraviolet germicidal light sources 20 in the air duct 11 can also be increased. The airflow driving module 30 is activated to generate airflow from the at least one air inlet 122 to the at least one air outlet 132 through the air duct portion 11 . In practice, the airflow driving module 30 may use a centrifugal fan, an axial fan, a cross-flow fan, or a combination of a plurality of fans.

The control module 40 is electrically connected to the lighting lamp 112 , the ultraviolet germicidal light sources 20 and the airflow driving module 30 , and its function is to control the opening or closing of the electrical connection elements. Please refer to FIG. 7 , which is a circuit diagram of the control module 40 of the intelligent full-time germicidal lighting group 1 (the part shown by the dotted line). The control module 40 includes a power conversion unit 41 , an operation interface 42 , a control unit 43 and a communication unit 44 . The power conversion unit 41 is electrically connected to an external power switch 3, and the power switch 3 is connected to a power grid 3A to obtain AC power from the power grid 3A. When the power switch 3 is turned on, the power conversion unit 41 receives the alternating current from the power switch 3 and performs step-down and conversion to obtain a working power. The operation interface 42 is used to connect an external operation device 4, such as a wire control box, a wireless remote controller, a mobile communication device, or even a smart phone loaded with an APP. Therefore, the operation interface 42 can be a USB connector, an RJ10 connector, an RJ45 connector, an infrared signal transceiver module or a mobile communication module (3G, 4G or 5G).

The control unit 43 is electrically connected to the power conversion unit 41 , the lighting lamp 112 , the ultraviolet germicidal light sources 20 and the airflow drive module 30 , and is connected to the operation interface 42 by signals, and can perform the following operations: A. Receive a signal from the operation device 4 . For a long-term global working signal, the lighting lamp 112, the ultraviolet germicidal light sources 20 and the airflow driving module 30 are continuously turned on; and B. Receive a short-term half-field working signal from the operating device 4, turn off the lighting lamp 112, and continue to turn on the The ultraviolet sterilization light sources 20 and the airflow driving module 30 have at least one operation time. Operation A is used in a closed room where there are crowds of people and lighting is required. At this time, disinfection and sterilization operate simultaneously. The time can be unlimited, but it needs to consume electricity. Operation B is used in a closed room where there are no crowds, but disinfection and sterilization are required. At this time, the lighting lamp 112 is off, and the ultraviolet germicidal light source 20 And the airflow driving module 30 continues to operate in the outer casing 10 . Of course, time does not need to be maintained all the time, which will consume unnecessary power. Therefore, the operation time is a basic sterilization time, such as one hour.

The communication unit 44 is signally connected to the control unit 43 . The communication unit 44 can be signal-connected with the communication unit 44 in the other intelligent full-time germicidal lighting group 1 , so as to transmit the working signal from the operating device 4 to the signal-connected smart full-time germicidal lighting group 1 . In addition, the communication unit 44 can also be designed to synchronize the operation of the intelligent full-time germicidal lighting group 1 connected by all signals, for example, to set when to perform operation A and when to perform operation B. The communication unit 44 is very simple in construction and may be a power line contact. The signal connection between the intelligent full-time germicidal lighting group 1 is made through the power line between the communication units 44 . The signal of the communication unit 44 can be represented by the level of potential or the change of frequency.

Please refer to FIG. 8 , which is a schematic diagram of the appearance of another smart full-time germicidal lighting lamp group 2 according to an embodiment of the present invention. In order to simplify the description, the same symbols as those in FIG. 1 are used in FIG. 8, and their functions and names are also the same. Comparing the smart full-time germicidal lighting group 1 and the smart full-time germicidal lighting group 2, it can be found that the latter has the following differences. First, the outer casing 10 is rectangular. In practice, the outer casing 10 can be a rectangle of 60 cm x 120 cm, so as to conform to the size of the calcium silicate board of the current light steel frame ceiling. Of course, there are other rectangular dimensions, which are not limited by the present invention. Second, the air outlet 13 does not have a curved arc section 133, but is replaced by a 90-degree bending structure. Although this approach will increase the noise, its production cost can be reduced. Third, there is only one air inlet 122 and one air outlet 132 respectively, but the area is large. This method not only reduces the production cost, but also facilitates the removal and cleaning of the filter screen on it, but its appearance may not be good. Fourth, the lighting lamp 112 uses a single annular fluorescent lamp.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The protection scope of the present invention shall be determined by the scope of the appended patent application.
