Description

The present invention relates to a lighting device with a attractant source protecting cover.

  2. Description of the Related Art Conventionally, lighting fixtures that utilize so-called luminescent properties of insects, in which insects gather in response to light in the ultraviolet region, are known. For example, an attracting light source that emits light including ultraviolet light that attracts insects (hereinafter, such light is referred to as attracting light, and the effect of attracting insects by attracting light is referred to as an attracting effect) is known. Luminaires with an attractive light source are known. In such a lighting fixture, in order to prevent scattering of a member such as glass constituting the attraction light source when the attraction light source is damaged by an external impact, it is known that the attraction light source is covered with an anti-scattering film. ing.

  However, when such a scattering prevention film is used, there is a problem in that the film cannot be reused at the time of replacement of the attracting light source and the running cost becomes high. Moreover, since the anti-scattering film was directly attached to the attracting light source, the effect of preventing damage to the attracting light source was hardly obtained when an external impact was applied to the lighting fixture.

By the way, an ultraviolet radiation lamp having an anti-scattering function having a double structure in which an ultraviolet radiation lamp mainly emitting 200 nm to 400 nm is covered with a covering having a diameter larger than the diameter of the ultraviolet radiation lamp, An ultraviolet radiation lamp is known in which the end portion of the radiation lamp is sealed with a fluororesin coating so that a hollow portion is formed between the ultraviolet irradiation lamp and the fluororesin coating (see, for example, Patent Document 1).
JP 2004-281321 A

  The ultraviolet radiation lamp described in Patent Document 1 is provided with a hollow portion between the ultraviolet irradiation lamp and the fluororesin coating body, thereby preventing deterioration of the coating body due to ultraviolet rays and preventing scattering of the ultraviolet radiation lamp due to external impact. However, sufficient studies have not been made on the attracting light for attracting insects, and it has not been possible to obtain a high attracting effect while preventing damage and scattering of the attracting light source.

  The present invention has been made in view of the above points, and can recycle the attracting light source protective cover even after replacing the attracting light source, can prevent damage to the attracting light source due to external impact, and is high. It is an object of the present invention to provide an attracting light source protective cover capable of realizing an attracting effect, and a lighting fixture provided with the attracting light source protective cover.

In order to achieve the above object, the invention according to claim 1 is an emission spectrum light that is approximated to an insect light curve, has a maximum peak wavelength in the near-ultraviolet region in the vicinity of a wavelength of 365 nm, and has a wavelength component of 250 nm or less being zero. An attracting light source that emits light , a cover member that is disposed so as to cover the light emitting surface of the cited light source, and that is formed of a material that efficiently transmits the emission spectrum, and the cover member is detachable from the attracting light source A cover fixing member that is fixed to the light source storage portion that is formed by at least the cover member and the cover fixing member and stores the attracting light source in a sealed state, and the attracting light source is a straight tube lamp, the cover member has a tube shape with an inner diameter of that is larger than the outer diameter of the straight tube lamp, the cover fixing member has an inner diameter the straight tube A tube-shaped lamp fitting portion fitted to an end of the straight tubular lamp, and an inner diameter is substantially the same as the outer diameter of the cover member. a cover member engaging portion of the tube-shaped holding the fitted with the cover member to the end portion of the straight tube lamp in a state spaced by a predetermined distance, wherein the light source accommodating portion, said cover member, It is formed by the two cover fixing members attached to both ends of the cover member .

The invention of claim 2 is the illumination apparatus according to claim 1, wherein, further comprising a trapping / insecticidal member for capturing or combating insects which are attracted by the attractant source.

According to the lighting apparatus including the attracting light source protection cover according to claim 1, since the cover member is formed of a material that efficiently transmits the emission spectrum approximated to the insect light curve, such a A high attraction effect can be realized when used by being attached to an attracting light source that emits an emission spectrum. Moreover, since the cover member is detachably fixed to the attracting light source by the cover fixing member, it can be reused even after the attracting light source is replaced. The cover member is, in the case of using a straight tubular lamp as an attractant light source is fixed spaced by a predetermined distance from the attraction source, attractant source, accommodated in the light source storage part which is more formed in the cover member and the cover fixing member Therefore, the external impact applied to the cover member is not directly applied to the attracting light source. For this reason, damage to the attracting light source can be prevented.

According to the lighting device of the second aspect , since the insect capturing / insecticing member is provided, the insect attracted by the light emitted from the attracting light source can be captured or exterminated.

Hereinafter, the lighting fixture provided with the attraction light source protective cover which concerns on the 1st Embodiment of this invention is demonstrated with reference to FIG. 1 thru | or FIG. As shown in FIG. 1, the luminaire 1 includes an attracting light source 2 that emits an emission spectrum that approximates the insect light curve, and an attracting light source protective cover 3 in which the attracting light source 2 is housed.
