Description

  The present invention relates to a lighting fixture.

  Conventionally, there has been known a lighting fixture provided with a light-shielding plate that irradiates light from a light source inside the fixture only in a specific direction in order to prevent light leakage from occurring in a direction other than the target direction. (For example, refer to Patent Document 1).

JP 11-213718 A (Claim 1, paragraph 0013, FIG. 1)

  However, the conventional lighting fixtures may cause light leakage to the residential side, particularly when the street lamp is installed adjacent to the residence, especially on the floor lower than the light source of the lighting fixture.

  An object of the present invention is to provide a lighting fixture that can maintain light distribution in a target direction and can effectively suppress light damage due to light leakage to a residence or the like.

  The present invention includes a main body having a lamp inside and having a light-transmitting member whose upper surface is released and capable of irradiating light from the lamp in the entire circumferential direction, and an upper cover attached to the release portion of the upper surface of the main body. A coupling means for coupling the upper cover and the main body, and a light shielding plate for shielding light in a horizontal direction and a downward direction, and an inner surface of the translucent member at a side end portion of the light shielding plate The protrusion piece arrange | positioned between is provided.

  Here, the side edge of the protruding piece of the light shielding plate is aligned with the inner surface of the translucent member.

  The light shielding plate has flexibility.

  Further, an elastic material is provided between a side edge of the protruding piece of the light shielding plate and the light transmitting member.

  According to the present invention, since the protruding piece is provided at the side end portion of the light shielding plate, the gap between the side edge of the light shielding plate and the translucent member can be reduced, and light leakage from this gap can be suppressed. , Light pollution can be suppressed.

Hereinafter, the lighting fixture of embodiment which concerns on this invention is demonstrated with reference to drawings.
FIG. 1 shows a lighting fixture 10 according to an embodiment of the present invention. This luminaire 10 includes a main body 13 having a lamp 11 therein, an upper surface being opened, and a globe 12 that is a translucent member capable of irradiating light from the lamp 11 in the entire circumferential direction. Moreover, the upper cover 14 provided in the open part in the upper surface of the globe 12 is provided.

Furthermore, a light shielding plate 16 that shields light in a part or all (a part in the present embodiment) in the horizontal direction and the downward direction of the lamp 11 is provided. At the end of the light shielding plate 16, a protruding piece 17 that protrudes toward the inner surface of the globe 12 is provided.
The light shielding plate 16 is coupled to the main body 13 via the coupling means 15 (15A, 15B).

Next, each of the above components will be described.
As shown in FIG. 2, the upper cover 14 and the globe 12 are each formed into a hollow hemisphere that is convex upward or convex downward, and their respective diameter surfaces are combined and assembled into a spherical shape. The lamp 11 and the light shielding plate 16 are disposed in the globe 12. A support 18 for attaching to a pole or the like is provided below the globe 12.

  The light shielding plate 16 is formed in a semicircular shape extending downward from the diameter portion of the globe 12. In addition, projecting pieces 17 projecting outward are provided on both sides of the light shielding plate 16. The protruding piece 17 is disposed in the gap between the light shielding plate 16 and the globe 12.

  As shown in FIG. 3, the side edge 19 of the protruding piece 17 is formed in an arc shape so that the entire side edge 19 abuts on or approaches the inner surface of the globe 12. As shown in FIG. 4, the coupling means 15 </ b> A is provided on the light shielding plate 16. The coupling means 15 </ b> A is provided with a lateral notch 20 at a portion protruding upward from the upper edge of the light shielding plate 16.

  In order to attach the light shielding plate 16 to the main body 13, the coupling means 15 </ b> A attached to the light shielding plate 16 with respect to a screw 30 (see FIG. 2) erected on an annular connection fitting 15 </ b> B provided inside the globe 12. It can be easily attached by engaging the notch 20.

  The maximum total width of the light shielding plate 16 and the protruding piece 17 is greater than the diameter of the inner surface of the globe 12. The light shielding plate 16 and the protruding piece 17 are preferably made of a flexible material such as aluminum. In order to insert the light shielding plate 16 into the globe 12, as shown in FIG. 5, both side ends of the projecting pieces 17, 17 of the light shielding plate 16 may be curved inward and inserted into the globe 12.

  In addition, as shown in FIG. 6, the elastic material 21 which contacts the inner surface of the globe 12 is provided on the side edge of the projecting piece 17 of the light shielding plate 16, so that a gap between the projecting piece 17 and the inner surface of the globe 12 is provided. Almost completely, it is possible to more reliably suppress the occurrence of light pollution.

  In addition, as shown in FIG. 7, it is possible to provide the lighting fixture 25 with a circular flat plate-like upper cover 26 and further provide a curved portion 28 that covers the lamp 11 at the center of the light shielding plate 27. This facilitates the processing of the upper cover 26 and facilitates the attachment of the light shielding plate 27.

  According to the lighting fixture 10, the globe 12 that irradiates the light of the lamp 11 in the entire circumferential direction includes the light shielding plate 16 that shields part or all of the light in the horizontal direction and the downward direction. A protruding piece 17 protruding in the direction of the inner surface of the globe 12 is provided at the portion. Accordingly, it is possible to reduce the gap between the inner surface of the globe 12 and the side edge of the light shielding plate 16 and suppress light from leaking from between the inner surface of the globe 12 and the light shielding plate 16 to cause light damage.

  Moreover, since the side edge part of the protrusion piece 17 in the light shielding plate 16 has a shape along the inner surface of the globe 12, the gap between the inner surface of the globe 12 and the side edge of the light shielding plate 16 is further reduced or eliminated. Further, light leakage from between the inner surface of the globe 12 and the light shielding plate 16 and light damage can be further suppressed.

  Further, since the light shielding plate 16 has flexibility, the light shielding plate 16 can be easily inserted into the globe 12 by being deformed. Therefore, it can be easily attached to a glove in an existing lighting fixture with the protruding piece 17 provided outside the light shielding plate 16.

  Further, since the elastic material 21 is provided between the side edge of the protruding piece 17 of the light shielding plate 16 and the globe 12, the gap between the protruding piece 17 and the globe 12 can be almost completely eliminated, and the light The occurrence of harm can be more reliably suppressed.
