Description

  The present invention relates to a lighting fixture using an ultraviolet lamp and a vinyl house using the lighting fixture.

  In some cases, a growing area covered with an outer member such as a vinyl house is used as a means for growing crops. Although it is not limited to such a breeding place, conventionally, in the cultivation of agricultural products, pesticides have been dealt with as control measures against diseases such as powdery mildew, downy mildew, and anthracnose.

  However, due to the impact on the human body and the growing social need for pesticide-free, producers want to avoid using pesticides as much as possible. These fungi such as powdery mildew and anthracnose are highly dependent on ultraviolet rays, and it is known that these disease-causing bacteria can be effectively reduced by irradiating ultraviolet rays with an appropriate amount of radiation.

  Then, the lighting fixture provided with the light source which radiates | emits the light containing an ultraviolet-ray is proposed (for example, refer patent document 1).

According to the said patent document 1, the disease resistance of agricultural products can be induced | guided | derived with an ultraviolet-ray.
Therefore, it can be expected that the yield will be increased by irradiating the crops with ultraviolet rays without being violated by diseases.

(2) Effects on eyes: Inducing cataracts and snowy eyes.
(3) Influence on immunity: Exposure to ultraviolet rays for a long period of time induces a decrease in immunity.

  As described above, excessive exposure to ultraviolet rays is not preferable in terms of health for people such as farmers who use light sources having ultraviolet rays.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a lighting apparatus and a vinyl house that can be protected by reducing the influence of ultraviolet rays on the human body.

Lighting device according to the present invention, an ultraviolet lamp straight tube, provided along the UV lamp, a reflector whose both ends are opened, to have a portion located above the UV lamps, the reflecting plate of an outer, before Symbol reflector, wherein it above a than the portion located above the UV lamps, and the provided above a is located at one end of the ultraviolet lamp, the electrical signal upon detection of human And a human sensor for turning off the ultraviolet lamp .

In the present invention, the human sensor is provided above the outer side of the reflecting plate that is open on both sides.
Thereby, even if the surface of the detection part of the human sensor is made of plastic, it is not irradiated with ultraviolet rays from the ultraviolet lamp.
Therefore, stable sensing can be performed without causing deterioration due to ultraviolet irradiation.

In the present invention, the human sensor generates an electrical signal when a person approaches.
This automatically turns off the UV lamp when a person approaches the lighting fixture.
Therefore, it is possible to protect the human body by reducing the influence of the ultraviolet ray on the human body without irradiating the person with the ultraviolet ray.

  The vinyl house which concerns on this invention has arrange | positioned the lighting fixture so that the said human sensor of the said lighting fixture may be located in the entrance side.

According to the lighting fixture and the vinyl house of the present invention, a straight tubular ultraviolet lamp, a reflecting plate provided along the ultraviolet lamp and open on both sides thereof, provided outside the reflecting plate and above the reflecting plate. And a human sensor.
Thereby, it has the effect that it can protect by reducing the influence of the ultraviolet-ray with respect to a human body.

The vertical sectional view seen from the side of the lighting fixture of one embodiment concerning the present invention Front view of the luminaire shown in FIG. The partially broken external appearance perspective view of the vinyl house of one Embodiment concerning this invention Vertical sectional view of the entrance and exit side of the vinyl house shown in FIG.

  Hereinafter, a lighting apparatus and a vinyl house according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, a lighting fixture 10 according to an embodiment of the present invention includes a main body case 11, a lighting device 12, a reflector 13, a pair of sockets 14, and a pair of socket bases 15. An ultraviolet lamp 16 that is a tube lamp and a human sensor 17 are provided.

  A lighting device 12 for lighting the ultraviolet lamp 16 is fixed inside the main body case 11.

  A socket base 15 for attaching a socket 14 is fixed to both ends of the main body case 11 in the longitudinal direction, and an ultraviolet lamp 16 is detachably attached to the socket 14.

  The human sensor 17 is an infrared sensor that detects an element having a temperature difference from the ambient temperature in a sensing area using, for example, infrared rays and generates an electric signal. The human sensor 17 is fixed to the side portion of the main body case 11. The sensitivity of the human sensor 17 is not constant and can be adjusted according to the use environment.

  As shown in FIG. 2, the main body case 11 has an opening, and a reflection plate 13 is attached so as to close the opening. The reflecting plate 13 is open at both ends in order to increase the irradiation area of the ultraviolet rays from the ultraviolet lamp 16.

  The shape of the reflector 13 is a parabolic shape with respect to the shape of the ultraviolet lamp 16 in the cross-sectional direction, focusing on the center of the ultraviolet lamp 16 with respect to the side surface portion of the main body.

  By forming the reflector 13 in such a shape, it is possible to obtain an ultraviolet irradiation shape having a peak in the direction of about 60 °, with the ultraviolet irradiation direction in the cross-sectional direction of the ultraviolet lamp 16 being 0 ° immediately below the fixture.

The human sensor 17 is attached outside and above the reflector 13 that is not irradiated with ultraviolet rays from the ultraviolet lamp 16. The reason is that the surface of the detection unit of the human sensor is generally made of plastic, and there is a possibility that the function may not be satisfied when the plastic detection unit is significantly deteriorated by yellowing or the like. .
Therefore, even if the surface of the detection part of the human sensor 17 is made of plastic, it is not irradiated with ultraviolet rays from the ultraviolet lamp 16.

Such a lighting fixture 10 is attached to, for example, a ceiling of a building or the top of a vinyl house which will be described later, and the ultraviolet lamp 16 is turned on by turning on a power switch (not shown). The human sensor 17 generates an electrical signal when a person approaches when the ultraviolet lamp 16 is turned on.
The luminaire 10 automatically turns off the ultraviolet lamp 16 when a person approaches.

  Next, the vinyl house 30 to which the lighting fixture 10 mentioned above is applied is demonstrated.

  As shown in FIG. 3, the vinyl house 30 is formed by covering a house skeleton 31 assembled by combining pipe members such as columns, rafters, cross beams, purlins, and base beams with a covering member 32 made of vinyl.

  For example, when cultivating a crop 1 such as a strawberry, the vinyl house 30 is formed in a substantially semicircular cross-sectional shape having a diameter of about 7 m and has a total length of 50 to 100 m. In the vinyl house 30, the planting of about 6 cm is performed substantially linearly.

  The vinyl house 30 has an entrance / exit 34 on each side surface 33. The vinyl house 30 uses the lighting fixture 10 provided with the human sensor 17 and the lighting fixture 20 not provided with the human sensor. The structural material of the entrance / exit 34 is preferably made of a resin that can transmit infrared rays from the human sensor 17.

In the vinyl house 30, a plurality of lighting fixtures 10 and 20 are arranged at intervals on the inner surface of the top portion 35 so that the longitudinal direction of the ultraviolet lamp 16 is arranged in parallel with the ridges that are linearly attached.
By arranging the plurality of lighting fixtures 10 and 20 in parallel with the linearly planted ridges, the number of fixtures can be minimized, and uniform irradiance can be obtained on the plurality of ridges.

  As illustrated in FIG. 4, the vinyl house 30 has a lighting fixture 10 in which the human sensor 17 is disposed on the entrance 34 side. The human sensor 17 has a sensing area A toward the entrance 34.

  The lighting device included in the lighting fixture 20 that does not include the motion sensor is connected in series to the lighting device 12 of the lighting fixture 10 that includes the motion sensor 17, and the lighting fixtures 10 and 20 are not equipped with a solar radiation sensor or the like. It is used by being connected to the illustrated power supply circuit.

  Therefore, when the ultraviolet lamps 16 of the lighting fixtures 10 and 20 are turned on by driving the power supply circuit, a person including a farmer or the like approaches the entrance / exit 34 of the vinyl house 30 from the outside. Eventually, the person enters the detection area A of the human sensor 17.

Then, the human sensor 17 generates an electric signal, turns off the ultraviolet lamp 16 through the lighting device 12 of the lighting fixture 10, and turns off the ultraviolet lamps of the other lighting fixtures 20.
Thereby, the vinyl house 30 can automatically turn off the ultraviolet lamps 16 of the lighting fixtures 10 and 20 before a person enters the inside.

In the lighting fixture 10 of this embodiment, the human sensor 17 is provided above the outer side of the reflecting plate 13 opened on both sides.
Thereby, even if the surface of the detection part of the human sensor 17 is made of plastic, it is not irradiated with ultraviolet rays from the ultraviolet lamp 16.
Therefore, stable sensing can be performed without causing deterioration due to ultraviolet irradiation.

In the lighting fixture 10 of this embodiment, the human sensor 17 generates an electrical signal when a person approaches.
Thereby, when a person approaches the lighting apparatus 10, the ultraviolet lamp 16 is automatically turned off.
Therefore, it is possible to protect the human body by reducing the influence of the ultraviolet ray on the human body without irradiating the person with the ultraviolet ray.

In the vinyl house 30 of the present embodiment, when a person including a farmer approaches the entrance / exit 34 of the vinyl house 30, the human sensor 17 generates an electrical signal and turns off the ultraviolet lamp 16.
This automatically turns off the ultraviolet lamp 16 before a person enters the vinyl house 30.
Therefore, it is possible to protect the human body by reducing the influence of the ultraviolet ray on the human body without irradiating the person with the ultraviolet ray.

  Note that the lighting device 12, the reflector 13, the socket 14, the socket base 15, the ultraviolet lamp 16 and the like used in each of the embodiments are not limited to those illustrated, and can be appropriately changed.
