Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a luminaire with a germicidal lamp.

[0002]

2. Description of the Related Art FIG. 7 is a perspective view of a conventional example according to the present invention.
FIG. 8 shows a cross-sectional view of a main part.

This germicidal lighting device is provided with a germicidal lamp 7 at a position in the duct 5 connecting the general lighting unit accommodating the general lighting lamp and the air inlet 6 and the air outlet which cannot be directly seen from the outside. And a germicidal lamp unit including a fan 2.

Here, a general illumination lamp (not shown)
Is the air inlet 6 of the duct 5 on the lower surface of the appliance body 1.
It is mounted between a pair of lamp sockets 3 mounted on the side surface of a concave portion (that is, the plate 4) provided between the lamp socket 3 and the air outlet. The plate 4 is formed in a substantially L-shaped cross section by a vertical plane and a horizontal plane. The vertical plane is a lamp socket base, and an end of the horizontal plane is connected to one end of the air suction port 6.

[0005] The germicidal lamp 7 is mounted between a pair of lamp sockets 8 attached to a position facing the air flow path in the duct 5. Photochemical reaction by ultraviolet irradiation to the atmosphere decomposes harmful unreacted ozone remaining in the atmosphere into harmless ones, prevents harmful ozone from being discharged from the instrument body 1 and sterilizes the atmosphere. I do. Moreover, since the germicidal lamp 7 is disposed at a position in the instrument main body 1 where a person cannot directly look, harmful ultraviolet rays are not emitted from the instrument main body 1 to the outside.

[0006] By rotating the fan 2 attached to the portion of the duct 5 facing the air flow path, the air is forced to flow from the air inlet 6 to the air outlet, so that the indoor air is removed. The flow direction of the atmosphere is kept constant without being affected by convection or the like, and the remaining ozone is prevented from being erroneously blown out from the air inlet 6. In addition, by forcibly flowing the air from the air inlet 6 toward the air outlet, the flow rate of the air is increased to increase the sterilizing ability of the air, and the ozone released from the instrument body 1 to the outside is sufficiently reduced. .

[0007]

However, the lighting equipment as shown in the above-mentioned conventional example has the following first problem. Since the plate 4 is formed to have a substantially L-shaped cross section between the vertical plane and the horizontal plane, if the opening of the general lighting unit is covered with the translucent panel, light leakage from the end of the translucent panel is eliminated. In other words, in order to eliminate light that does not transmit through the translucent panel, it is necessary to eliminate the gap between the vertical plane of the plate 4 and the end of the translucent panel. However, when a size error or the like of the plate 4 or the translucent panel occurs, the above-described gap occurs, and a vertical shift of the translucent panel occurs.

In order to solve the first problem, another means of using a light-transmitting panel integrally formed with an air inlet and an air outlet can be considered. If the light-transmitting panel integrally formed with the above is lowered due to its own weight or the like, the second problem occurs that the airtightness of the duct is reduced and the sterilizing power is reduced. In addition, when a light-transmitting panel in which an air inlet and an air outlet are formed integrally is used, a third problem arises in that the existing light-transmitting panel cannot be used, resulting in an increase in cost. I will.

SUMMARY OF THE INVENTION The present invention has been made in view of all of the above problems, and an object of the present invention is to provide a luminaire with a germicidal lamp capable of preventing vertical displacement of a light-transmitting panel and improving airtightness of a duct. At low cost.

[0010]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, a general lighting lamp is housed, and a light-transmitting opening is covered with a removable light-transmitting panel. In a lighting fixture with a germicidal lamp comprising a lighting unit and a germicidal lamp unit provided with a germicidal lamp and a fan in a duct connecting between the air inlet and the air outlet, the translucent panels of the general lighting unit are arranged on both sides. , A plate having an air inlet and a plate having an air outlet are provided.

According to the second aspect of the present invention, the duct is
It is characterized in that it stands up on both sides of the general lighting unit and is arranged on the back of the general lighting unit.

According to the third aspect of the present invention, the general lighting unit and the germicidal lamp unit are detachable from each other.

(Embodiment 1) FIG. 1 is a perspective view of a first embodiment according to the present invention, and FIG. 2 is a sectional view of a main part thereof.

The difference from the conventional example shown in FIGS. 7 and 8 is that
A plate having an air inlet 6 and a plate having an air outlet are provided so as to sandwich the translucent panel covering the opening of the general lighting unit on both sides, that is, a plate independent of the lamp socket base 9. 10 is provided with an air inlet or an air outlet, and the plate is configured to cover the opening of the duct. .

Here, as shown in FIGS. 3 and 4, the fixture body 1 is provided with a receiving member 21 on the inner surface of the general lighting unit, and the translucent panel 12 is provided with a receiving member near the periphery of the upper surface. At each of the portions corresponding to 21, a holding metal fitting 22 is formed by bending a resilient wire spring having a substantially straight distal end portion and a substantially straight body portion into a substantially V-shape. The holding metal fittings 22 have shaft supporting portions at both lower ends supported by bearings (not shown) provided on the upper surface of the light-transmitting panel 12, and the body portions oppose left and right by bending a wire spring into a substantially V shape. It has become. To attach the translucent panel 12,
The holding member 22 is inserted into the receiving member 21 and attached in a state where the tip end side of the holding member 22 is passed through the receiving member 21. Is mounted and supported.
When removing the translucent panel 12 from the apparatus main body 1, the translucent panel 12 is pulled down from the receiver 21.

The lamp socket base 9 and the air inlet 6
By providing a concave portion 23 between them and locking the end of the translucent panel 12, light leakage from the end of the translucent panel can be eliminated. In addition, existing translucent panels can be used.

With the above-described configuration, it is possible to provide a low-cost lighting fixture with a germicidal lamp which can prevent the translucent panel from vertical displacement and can improve the airtightness of the duct.

(Embodiment 2) FIGS. 5 and 6 show side views of a second embodiment according to the present invention.

The difference from the first embodiment shown in FIGS. 1 to 4 is that the general lighting unit and the germicidal lamp unit can be separated and connected. The same components as those described above are denoted by the same reference numerals and description thereof will be omitted.

The general lighting unit 11 has a box-like shape with an opening on the lower surface, a plate 9 serving as a socket base for the lamp socket 3 is provided on the inner surface thereof, and the opening is covered with a translucent panel 12. The germicidal lamp unit 31 has the same configuration as the germicidal lamp unit shown in the first embodiment.

In the concave portion of the germicidal lamp unit 31, a unit receiver (not shown) is provided.
A unit connector 13 for connecting the germicidal lamp unit 31 and the general lighting unit 11 is attached to each of the locations corresponding to the unit holder near the upper surface. Then, the general lighting unit 11 is attached to the germicidal lamp unit 31 by pushing up the general lighting unit 11 by aligning the unit connector 13 with the unit holder of the germicidal lamp unit 31.

[0022]

According to the first to third aspects of the present invention, a lighting device with a germicidal lamp can be provided at a low cost, which can prevent the translucent panel from vertical displacement and can improve the airtightness of the duct. .
