See FIG. 3) is formed. The irradiation space 30 is a space inside the cover member 40 where the ultraviolet rays generated by the UV-LED 15 of the ultraviolet LED panel 10 are irradiated, and is a portion with hatching in FIG. In the indoor lighting air purification device 1, the dimension in the direction along the first and second side plate portions 21 and 22 is the "length", and the direction from the first side plate portion 21 to the second side plate portion 22 ( The dimension (direction intersecting the first and second side plate portions 21 and 22) is defined as "width".

As shown in FIG. 4, the top plate portion 20 is a long rectangular plate material having a pair of longitudinal sides 20a and 20b and a pair of lateral sides 20c and 20d. The long sides 20a and 20b are formed larger than the short sides 20c and 20d. The first and second side plate portions 21 and 22, respectively, are formed along the longitudinal sides 20a and 20b, respectively. Further, as shown in FIG. 1, the ultraviolet LED panel 10 is fixed to the inner surface of the top plate portion 20 (the surface on the side forming the irradiation space 30). The ultraviolet LED panel 10 is fixed so that the UV-LED 15 faces the irradiation space 30 side and the longitudinal sides 11a and 11a are arranged along the longitudinal sides 20a and 20b, respectively.

The first and second side plate portions 21 and 22 are formed so as to be orthogonal to the top plate portion 20. The first and second side plate portions 21 and 22 have lengths corresponding to the longitudinal sides 20a and 20b of the top plate portion 20, respectively, and the width of the top plate portion 20 (the lengths of the short sides 20c and 20d). Has a shorter height than.

Further, as shown in detail in FIGS. 5 and 6, the first and second side plate portions 21 and 22 have first and second ventilation holes 21a and 22a, respectively.

The first ventilation hole 21a is a circular hole portion, and is connected from the outside of the first side plate portion 21 to the effective space 31 described later in the irradiation space 30. As shown in FIG. 5, the first ventilation hole 21a is formed at a position separated from the upper end portion (top plate portion 20) in the height direction of the first side plate portion 21 by a first distance d21. Further, three first ventilation holes 21a are arranged along the height direction of the first side plate portion 21, and substantially of the first side plate portion 21 along the length direction of the first side plate portion 21. Many are formed throughout.

The second ventilation hole 22a is a circular hole portion, and is connected from the outside of the second side plate portion 22 to the effective space 31. As shown in FIG. 6, the second ventilation hole 22a is separated from the upper end portion (top plate portion 20) in the height direction of the second side plate portion 22 by a second spacing d22 smaller than the first spacing d21. It is formed at the position. Further, one second ventilation hole 22a is arranged along the height direction of the second side plate portion 22, and the second side plate portion 22 is substantially along the length direction of the second side plate portion 22. Many are formed throughout.

Then, as shown in FIG. 4, the first and second side plate portions 21 and 22 are formed with receiving plate portions 23 and 24 at the lower end portions (end portions on the side away from the top plate portion 20), respectively. The receiving plate portions 23 and 24 are formed so as to project from the lower ends of the first and second side plate portions 21 and 22, toward the irradiation space 30 side, respectively, with a size smaller than the width of the top plate portion 20. ing. Then, as shown in FIG. 1, the partition member 50 is supported by placing the airflow guide plate 51 and the support plate 52, which will be described later, on the receiving plate portions 23 and 24, respectively.

As shown in detail in FIGS. 7 and 10, the partition member 50 is a member formed of a metal such as aluminum or a resin, and has an air flow guide plate 51 and a support plate 52. The partition member 50 is formed so that the airflow guide plate 51 and the support plate 52 form an acute angle α.

The airflow guide plate 51 is a flat plate-shaped member, has a length corresponding to the length of the top plate portion 20, and has a width slightly larger than the width of the top plate portion 20. Further, as shown in FIG. 1, the airflow guide plate 51 has a first side plate portion 21 (first ventilation hole 21a) to a second side plate portion 22 (second ventilation hole 22a) in the irradiation space 30. It is arranged (or fixed to the cover member 40) in an upwardly inclined manner toward the cover member 40. The support plate 52 is connected to the upper end portion of the airflow guide plate 51 (the end portion on the second side plate portion 22 side).

The support plate 52 is a flat plate material, has a length corresponding to the length of the top plate portion 20, and has a height slightly smaller than the heights of the first and second side plate portions 21, 22. ing.

Since the partition member 50 is arranged in the irradiation space 30, the irradiation space 30 is divided into an effective space 31 and a space other than the effective space 31 (non-effective space 32), as shown in FIG. The space is partitioned (divided) by an airflow guide plate 51.

Further, as shown in FIG. 10, an ultraviolet shielding portion 53 is formed on the surface of the airflow guiding plate 51 on the front side (top plate portion 20 side). In FIG. 10, the ultraviolet shielding portion 53 is formed in the portion where the dots are attached.

The effective space 31 is a portion of the irradiation space 30 partitioned by the airflow guide plate 51, and is a space on the top plate portion 20 side close to the top plate portion 20. In FIG. 1, the hatched portion is the irradiation space 30, the hatched portion is the effective space 31 with dots, and the non-dotted portion is the ineffective space 32. Is.

Since the effective space 31 is the space on the top plate portion 20 side, the light emitting L of the UV-LED 15 and the ultraviolet rays 10X (details will be described later) are more effectively irradiated than the ineffective space 32. On the other hand, the ineffective space 32 is a space separated from the top plate portion 20 with the airflow guide plate 51 interposed therebetween. Since the ultraviolet shielding portion 53 is formed on the surface of the airflow guiding plate 51, the ultraviolet 10X of the UV-LED 15 is not irradiated.

Then, a resin-made ultraviolet cut film or an ultraviolet filter is attached to the front surface of the airflow guide plate 51 to form the ultraviolet shielding portion 53. For example, when a film having a predetermined thickness (for example, 4 mm or more) is formed by using a fluororesin that transmits ultraviolet rays and visible rays, the ultraviolet transmittance of the film is significantly suppressed. When the film thickness is larger (for example, 5 mm or more), the ultraviolet rays are substantially absorbed by the film. Therefore, when a film having a predetermined thickness (for example, 4 mm or more) is formed by using a fluororesin that transmits ultraviolet rays and visible rays, the film blocks or absorbs ultraviolet rays. Therefore, the film is fixed to the front surface of the airflow guide plate 51 by sticking or the like, so that the ultraviolet shielding portion 53 is formed. Further, in addition to ultraviolet transmission and visible light transmission, a film having a heat shield property can also be used.

As shown in FIG. 9, the cover members 60 and 70 at both ends are members formed in a substantially L shape. Both end cover members 60 and 70 have fixed end faces 61 and 71 and closed surfaces 62 and 72, respectively. The fixed end faces 61 and 71 each have a horizontal width corresponding to the width of the top plate portion 20 and a vertical width smaller than that. The closed surfaces 62 and 72 have a width corresponding to the width of the top plate portion 20 and a height corresponding to the height of the first and second side plate portions 21 and 22, respectively.

Then, as shown in FIG. 1, the both end cover members 60 and 70 are provided at both ends of the cover member 40 in the length direction as shown in FIG. 2 in a state where the partition member 50 is arranged in the irradiation space 30. Each is fixed. At that time, the fixed end portions 61 and 71 are fixed to the top plate portion 20 respectively in a state where the closing surfaces 62 and 72 close the openings 40a and 40b (see FIG. 4) in the length direction of the cover member 40, respectively. Has been done.

(Operation content and effect of indoor lighting air purification device 1)
Indoor lighting air purification device 1 is, for example, a hospital room, therapy room, Oite the room such as operating rooms or the like, are installed and used by being fixed to the room ceiling. At this time, when the power switch is turned on, power is supplied to the ultraviolet LED panel 10 from a power source (not shown).

Then, in the ultraviolet LED panel 10, each UV-LED 15 is turned on. As a result, as shown in FIG. 11, the light emitting L of each UV-LED15 is obtained, and the ultraviolet ray 10X is generated from each UV-LED15.

On the other hand, when the power switch is turned on, the irradiation space 30 is filled with inside air. The temperature of the inside air in the irradiation space 30 rises due to the heat generated by the UV-LED 15 accompanying the light emission L. Then, the shyness becomes lighter.

However, since the irradiation space 30 is divided into the effective space 31 and the ineffective space 32 by the airflow guide plate 51, the heat generated by the light emitting L reaches more to the inside air of the effective space 31 than in the ineffective space 32. In particular, when a film having a heat-shielding property is used as the ultraviolet shielding portion 53, the heat generated by the light emitting L is blocked by the airflow guide plate 51 and is not easily transmitted to the ineffective space 32. Therefore, the heat generated by the light emitting L reaches effectively by the inside air of the effective space 31.

The airflow guide plate 51 is arranged in an upward inclination from the first side plate portion 21 (first ventilation hole 21a) toward the second side plate portion 22 (second ventilation hole 22a).

Therefore, as shown in FIGS. 11 and 12, from the first side plate portion 21 (first ventilation hole 21a) to the second side plate portion 22 (second ventilation hole 22a) along the airflow guide plate 51. A gentle airflow af is formed. The airflow af moves along the airflow guide plate 51 toward the second ventilation hole 22a. Ultraviolet rays 10X are applied to the airflow af until the airflow af reaches the second ventilation hole 22a. As a result, the airflow af is purified by sterilizing, sterilizing, and eradicating floating bacteria and viruses.

Further, with the formation of the air flow af, the outside air af1 enters the effective space 31 from the outside of the first side plate portion 21 through the first ventilation hole 21a. The outside air af1 also receives heat generated by the light emission L of the UV-LED15, similarly to the airflow af described above. Therefore, the airflow af1 following the above-mentioned airflow af is formed. The airflow af1 also moves toward the second ventilation hole 22a along the airflow guide plate 51. Ultraviolet rays 10X are also irradiated until the airflow af1 reaches the second ventilation hole 22a. Therefore, the airflow af1 is also purified by sterilization, sterilization, sterilization, and the like.

As described above, the indoor lighting air purifying device 1 circulates the inside air in the room, and the ultraviolet rays 10X are irradiated while the inside air passes through the indoor lighting air purifying device 1. In this way, partial purification of the inside air is realized.

By continuing the partial purification of the inside air, the inside air can be purified over a wide range, and the effective purification of the inside air over a wide range is realized. Therefore, the indoor lighting air purification device 1 can improve the hygienic environment of the medical site such as a hospital room, a treatment room, an operating room, a waiting room of a medical institution, and a corridor. In particular, in places where many people gather, such as waiting rooms in medical institutions, there is a risk that infectious diseases will spread among the gathered people, but the indoor lighting air purification device 1 suppresses the risk of such infectious diseases spreading. Will be done.

The indoor lighting air purification device 1 is, for example, from being installed to fix the top plate portion 20 of the cover member 40 to the chamber ceiling, the light-emitting L is irradiated from above the room in the room. Thus, the interior lighting air purification device 1 can illuminate brightly a wide range of room. The indoor lighting air purification device 1 is suitable as an indoor lighting device.

On the other hand, since the indoor lighting air purification device 1 generates ultraviolet rays 10X , the ultraviolet rays 10X may hurt people near the indoor lighting air purification device 1.

However, in the indoor lighting air purification device 1, the ultraviolet shielding portion 53 is arranged on the front side of the UV-LED panel 10. Therefore, the ultraviolet rays 10X generated by the UV-LED panel 10 are blocked or absorbed by the ultraviolet shielding portion 53. Therefore, the ultraviolet 10X is generated from the UV-LED panel 10, and after the airflow af is sterilized and sterilized, the outside of the ultraviolet shielding portion 53 (on the non-effective space 32 side) is not irradiated. Therefore, there is no risk that people near the indoor lighting air purification device 1 will hurt their eyes.

On the other hand, in the indoor lighting air purification device 1, the circulation of the inside air, which is indispensable for purifying a wide range of the inside air, is entrusted to the temperature rise of the inside air due to the heat generation of the UV-LED panel 10 and the uphill partition member 50. There is. Therefore, it takes time for the inside air to be purified over a wide area. Therefore, in the present embodiment, the air purification method using the indoor lighting air purification device 1 is also characterized.

(Air purification method using indoor lighting air purification device 1)
In the air purification method according to the present embodiment, as shown in FIG. 13, the indoor lighting air purification device 1 is installed indoors by fixing the top plate portion 20 to the indoor ceiling 98. An air conditioner 99 as a means of blowing air is embedded in the indoor ceiling 98. Further, as shown in FIG. 14, four indoor lighting air purifying devices 1 are installed near the air conditioner 99 so as to surround the air conditioner 99.

Then, as shown in FIG. 13, the air conditioner 99 blows down the blower AF toward the lower part of the room. A part of the blower AF flows outward from the air conditioner 99. Since the inside air is circulated by such a blast AF, the inside air can be efficiently purified by utilizing the blast AF. Therefore, four indoor lighting air purification devices 1 are installed in the room so that the first side plate portion 21 is arranged on the windward side of the blower AF. Further, as shown in FIG. 14, the indoor lighting air purification device 1 is installed along the outer circumference of the air conditioner 99.

In this way, a part of the blower AF enters the effective space 31 from the first ventilation hole 21a of the first side plate portion 21 as the above-mentioned airflow af, passes through the effective space 31 and from the second ventilation hole 22a. Before it comes out, the airflow af is irradiated with ultraviolet rays 10X. Therefore, the inside air is efficiently purified.

According to this air purification method, purification of the inside air by utilizing the blower AF blown down from the air conditioner 99 as a blower means is realized. Since the blower AF is driven by the power of the air conditioner 99, it moves faster inside the indoor lighting air purifier 1 (than when the air conditioner 99 is not used). Therefore, according to this air purification method, the time until the inside air is extensively purified is shortened, and the inside air is efficiently purified.

(Modification example)
Next, with reference to FIG. 15, the indoor lighting air purification device 101 according to the modified example will be described. FIG. 15 is a perspective view in which both end cover members of the indoor lighting air purification device 101 are omitted.

The indoor lighting air purification device 101 includes an ultraviolet LED panel 110, a cover member 140, a partition member 150, and both end cover members (not shown).

The ultraviolet LED panel 110 is different from the ultraviolet LED panel 10 in that the shape of the substrate 111 and the arrangement of the ultraviolet LED chip 12 (not shown in FIG. 15) are different. The substrate 111 is formed in a rectangular shape like the substrate 11 of the ultraviolet LED panel 10, but the ratio of the lengths of the longitudinal side and the lateral side is different from that of the substrate 11. Further, in the substrate 11 of the ultraviolet LED panel 10, the longitudinal sides 11a and 11a were arranged along the first and second side plate portions 21 and 22 as shown in FIG. 3, but as shown in FIG. 15, the longitudinal sides 11a and 11a were arranged along the first and second side plate portions 21 and 22. In the substrate 111, the longitudinal sides 111a and 111a are arranged so as to intersect the first and second side plate portions 121 and 122, which will be described later.

The cover member 140 has a top plate portion 120, a first side plate portion 121 facing the top plate portion 120, and a second side plate portion 122. The top plate portion 120 is a rectangular plate material having a pair of short sides 120a and 120b and a pair of long sides 120c and 120d, and has a length of the long sides 120c and 120d and short sides 120a and 120b. The ratio is different from that of the top plate portion 20.

The first and second side plate portions 121 and 122 are formed so as to be orthogonal to the top plate portion 120 along the short sides 120a and 120b, respectively. A first vent hole 121a and a first vent hole 122a are formed, respectively. Two first ventilation holes 121a are arranged along the height direction near the lower end portion away from the top plate portion 120. One second ventilation hole 122a is arranged near the upper end portion on the top plate portion 120 side.

Is located in. Therefore, similarly to the indoor lighting air purification device 1, the airflow af (not shown in FIG. 15) moves from the first ventilation hole 121a toward the second ventilation hole 122a along the airflow guide plate 151. At that time, ultraviolet rays are irradiated from the ultraviolet LED chip 12 of the ultraviolet LED panel 110.

However, in the indoor lighting air purification device 101, the width of the airflow guide plate 151 is formed to be larger than the length. Therefore, as compared with the indoor lighting air purification device 1, the time required for the airflow af to reach the first side plate portion 121 to the second side plate portion 122 is longer, so that the ultraviolet rays 10X are irradiated for a longer time. .. Therefore, in the indoor lighting air purification device 101, purification such as sterilization, sterilization, and sterilization of the inside air is performed more effectively. In addition, the indoor lighting air purification device 101 has the same function and effect as the indoor lighting air purification device 1.

In the above embodiment, as the partition member, the partition member 50 having the airflow guide plate 51 and the support plate 52 and the partition member 150 having the airflow guide plate 151 and the support plate 152 will be described as an example. This embodiment is also applied to an indoor lighting air purification device having a partition member (not shown) having only the airflow guide plates 51 and 151 without supporting plates 52 and 152. In this case, the ends of the airflow guide plates 51 and 151 on the second side plate portions 22 and 122 are fixed to the second side plate portions 22 and 122 by adhesion, welding, etc., respectively, so that the airflow guide plate 51, 151 is arranged in an upward slope.

Further, in order to secure the brightness, the ultraviolet LED panels 10 and 110 may have an LED that generates visible light in addition to the UV-LED 15.

By applying the present invention, it is possible to obtain an indoor lighting air purification device capable of brightly illuminating a wide range of a room and effectively purifying the inside air over a wide range, and an air purification method using the same. The present invention can be used in the field of an indoor lighting air purification device and an air purification method using the device.
