Description

【0001】
【発明の属する技術分野】
本発明は、簡易形の投光器に防虫及び退色並びに光害防止効果を持たせる構造に関する。
【0002】
【従来の技術】
従来の簡易形投光器は、ランプホルダに、ランプを裸の状態で取り付ける為、ランプ固有の分光分布特性及び配光特性が、そのまま器具の照明特性となっていった。
【0003】
【発明が解決しようとする課題】
従来の簡易投光器は、図3の様に構成されており、ランプホルダに、ランプを裸の状態で取付ける為、ランプ固有の分光分布特性及び配光特性がそのまま器具の照明特性となり、夜間、昆虫を集め、周囲に不必要な光が漏れるという問題があった。
本発明の目的は、簡易投光器の前面にプリズム断面形状を持つカバーを設け、表面を紫外線吸収材を添加した合成樹脂皮膜で被覆し、防虫及び退色防止並びに光害防止機能を持たせることにある。
【0004】
【課題を解決するための手段】
上記目的を達成する為に、簡易投光器の前面にプリズム断面形状を持つカバーを設け、表面を紫外線吸収材を添加した合成樹脂皮膜で被覆したものである。
プリズム断面形状を持つカバーは、上方光束を抑える為、周囲に不必要な光が漏れるのを防止できる。又、カバー表面を、昆虫が最も強く感じる波長域をカットする紫外線吸収材を添加した合成樹脂皮膜で被覆するので、昆虫の集まるのを防ぎ、かつ、被照物の退色を防ぐことができる。
【0005】
【発明の実施の形態】
本発明の実施形態を図1・2により説明する。 本発明投光器は、ランプホルダ1とカバー5により構成されており、ランプホルダ1は、ランプソケット2、ランプ3で構成されている。
一方、カバー部分は、枠7に、紫外線吸収材入り合成樹脂被膜6を被覆したカバー5を取付け、それをランプホルダ1に取付けたシェード4から延びている4本の枠支持器具9に取付ビス8で固定している。 本実施例によれば、プリズム断面形状を持つカバー5は、上方光束を抑える為、周囲への光害を防止する効果がある。 又、カバー表面を、紫外線吸収材を添加した合成樹脂皮膜で被覆しているので、防虫と退色防止の効果がある。
【0008】
【発明の効果】
本発明によれば、プリズム断面形状のカバーにより、上方光束が抑えられるので、周囲への光害を防止する効果がある。 又、カバー表面を、紫外線吸収材入りの合成樹脂で被覆するので、夜間、昆虫が集まるのを防ぎ被照物の退色を防ぐ効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure for providing a simple floodlight with insect repellent, fading and light pollution prevention effects.
[0002]
[Prior art]
In the conventional simple projector, since the lamp is attached to the lamp holder in a bare state, the spectral distribution characteristics and the light distribution characteristics inherent to the lamp directly become the illumination characteristics of the fixture.
[0003]
[Problems to be solved by the invention]
The conventional simple floodlight is configured as shown in FIG. 3, and since the lamp is mounted on the lamp holder in a bare state, the spectral distribution characteristic and the light distribution characteristic inherent to the lamp are used as the illumination characteristics of the fixture without any change. And unnecessary light leaks to the surrounding area.
An object of the present invention is to provide a cover having a prism cross-sectional shape on the front surface of a simple floodlight, cover the surface with a synthetic resin film to which an ultraviolet absorbing material is added, and to provide insect-proof, fading prevention and light pollution prevention functions. .
[0004]
[Means for Solving the Problems]
In order to achieve the above object, a cover having a prism cross-sectional shape is provided on the front surface of the simple projector, and the surface is covered with a synthetic resin film to which an ultraviolet absorber is added.
The cover having the prism cross-sectional shape can suppress unnecessary light from leaking to the surroundings in order to suppress the upward light flux. In addition, since the cover surface is covered with a synthetic resin film to which an ultraviolet absorbing material that cuts the wavelength range that insects feel most strongly is added, it is possible to prevent insects from gathering and to prevent fading of illuminated objects.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. The floodlight of the present invention includes a lamp holder 1 and a cover 5, and the lamp holder 1 includes a lamp socket 2 and a lamp 3.
On the other hand, as for the cover part, a cover 5 covered with a synthetic resin film 6 containing an ultraviolet absorbing material is attached to a frame 7, and the cover 5 is attached to four frame supporting devices 9 extending from a shade 4 attached to the lamp holder 1. It is fixed at 8. According to the present embodiment, the cover 5 having the prism cross-sectional shape has an effect of preventing light pollution to the surroundings because the cover 5 suppresses the upward light flux. Further, since the cover surface is covered with a synthetic resin film to which an ultraviolet absorber is added, there is an effect of preventing insects and preventing fading.
[0008]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, since the upper luminous flux is suppressed by the cover of a prism cross-sectional shape, there exists an effect which prevents the light pollution to surroundings. Further, since the cover surface is covered with a synthetic resin containing an ultraviolet absorbing material, there is an effect of preventing insects from gathering at night and preventing fading of the illuminated object.

FIG. 2 is an enlarged view of a cross section of a cover having the prism cross-sectional shape.
FIG. 3 is a sectional view showing a conventional device.
