Description

  The present invention relates to a streetlight, and more particularly to a lamp that can project and illuminate not only the road surface and the like of the installation location.

  Traditionally, streetlights that illuminate road surfaces and the like have been installed at night to ensure the safety of walking and driving at night, and in particular, power lines are installed on power poles to easily receive power supply. Many street lamps are installed on the power pole.

Since such street lamps need to illuminate the road surface below, by installing a reflector on the top of the light emitting part such as a light bulb or a fluorescent lamp, the light (light quantity) emitted from the light emitting part is reduced. It is designed so that it can be reflected and illuminated downward without waste (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 7-141905

  However, in such a conventional street lamp, since a reflecting plate or the like is disposed on the upper part to illuminate the road surface below, it is not possible to illuminate the upper part of the street lamp. It was difficult to see the upper part by night illumination.

  Accordingly, an object of the present invention is to provide a streetlight that can be illuminated at the same time as the lower side by projecting upward as well as the lower side so that the upper side can be easily seen at night.

The light on the upper side of the projector is projected upward .

In this invention, in addition to the light on the lower side of the light emitting unit being projected downward by the lower light projecting unit , the light on the upper side of the light emitting unit is projected upward by the upper light projecting unit and Is also illuminated. Therefore, not only the lower road surface and the like (without blocking the lower illumination) but also the upper member can be illuminated, and the upper display can be easily seen at night.

  In addition to the specific matters of the first invention, the second invention of the streetlight that solves the above-described problem is that the light traveling between the lower light projecting unit and the upper light projecting unit is transmitted to the lower light projecting unit or the upper light projecting unit. A reflection plate that reflects on one or both of the parts is provided.

  In the present invention, light is reflected from the light emitting part that travels between the lower light projecting part and the upper light projecting part, and is projected from the lower light projecting part or the upper light projecting part. Therefore, the light from the light emitting unit can be projected without waste, and the need to unnecessarily increase the light amount of the light emitting unit can be eliminated.

In addition to the specific matter of the first or second invention, a third invention of a streetlight that solves the above-described problem is an installation section capable of installing a display plate that is illuminated by light projected above the upper light projecting section. Is provided.
The light emitting unit, the upper light projecting unit, and the lower light projecting unit may be disposed on both sides of the display unit to illuminate both sides of the display plate.

  In this invention, the display board installed in the upper part can be illuminated by the light projection from an upper light projection part. Therefore, a display board such as a signboard can be easily installed on the top, and can be used as an easy-to-see display at night.

  Thus, according to the present invention, it is possible to illuminate the light from the light emitting unit not only downward but also upward, and it is easy to see the upper display as well as the lower road surface. Therefore, it is possible to make it easy to see the upper display even at night without interfering with the lower illumination, and it is possible to notify desired information while ensuring safety on the road and the like.

As an embodiment of the present invention, in addition to having the above problem solving means as a basic configuration, an installation portion for installing the display plate in an upright state is provided at the center of the upper portion of the frame. A pair of light emitting units are provided in the frame so as to be positioned on both sides of the lower side and extend in parallel with the display panel. The frame transmits light on the lower side of the light emitting unit downward and projects the light. One lower light projecting section that emits light, a pair of upper light projecting sections for each light emitting section that emit light by transmitting the light on the upper side of the light emitting section upward, and the outside of the light on the upper side of the light emitting section A pair of reflecting plates for each light-emitting portion that reflects light in a range to be projected toward the upper display plate so as to extend in parallel with the light-emitting portion. By the light emitting part, the upper light projecting part and the reflector arranged in a state extending in parallel with each of the lower part It may be configured to illuminate both sides of the entire surface of the display panel from the bottom side of both sides of the display panel.
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described based on the drawings. 1-3 is a figure which shows one Embodiment of the streetlight based on this invention.
