Description

  In the present invention, it is a matter of course that a pedestrian, a bicycle, a baby carriage, a wheelchair, and the like so that the sidewalk space is easy to walk without barriers when passing through the sidewalk. The present invention relates to a structure of a sidewalk illuminator that is easy to walk, safe, inexpensive, high-class, and has a landscape that matches the surrounding environment.

  The lighting used on the sidewalks of buildings, parks, roads, etc. is often illuminated from the side columns and on top of tall columns, which is effective in places where there are many cars and people passing. However, in order to install the pillars, not only is the construction cost of the foundation and electricity high, but it also costs considerable maintenance, so the place where it is installed is limited, as a facility for many vulnerable people, The fact is that it is not widely spread.

Also, considering the brightness of road lighting from the viewpoint of energy efficiency, if lighting is performed from a height of 5 meters, the energy is attenuated by the square of the distance, so the efficiency is extremely poor, and light will reach the sidewalk. The fact is that it has attenuated to 1/25.

  According to the pedestrian crossing lighting device described in [Patent Document 1], as a problem, the driver who approaches the pedestrian crossing recognizes the presence of pedestrians, bicycles, etc. A pedestrian crossing lighting device that can be evoked is provided, and as a solution, the presence of a pedestrian or bicycle trying to cross a pedestrian crossing at night is detected by a detection sensor, and illumination is performed for a predetermined time based on the detection signal. Turn on the light to illuminate the crosswalk. Only when there are pedestrians or bicycles trying to cross the pedestrian crossing, this lighting etc. proves the entire pedestrian crossing, so there are pedestrians etc. for drivers traveling towards the pedestrian crossing It is easy to recognize, draws attention, and can effectively prevent accidents at pedestrian crossings, and is turned off when there are no pedestrians or bicycles, avoiding economic losses.

  However, with this type of lighting, lighting is necessary only when needed on a pedestrian crossing, but depending on the installation location, it is effective to install many in a general sidewalk space. Cannot be used.

The problem to be solved is to increase the sidewalk space that many people can walk with peace of mind by developing inexpensive and effective sidewalk lighting fixtures on dark sidewalks that are expensive and difficult to install.

The present invention is based on the fact that road lighting and sidewalk lighting that has been installed for a long time is installed from a high place by installing a tall column at the end of the road, and curbs using the latest LED technology. It has been researched and developed to make it possible to create sidewalk lighting that is excellent in landscape by installing it compactly on top.

  Recently, lighting used for roads has a lot of products using LEDs, and has excellent performance such as durability and stunning performance. Although it is still expensive, it is about to be used explosively. In order to be used in a large amount in the sidewalk space of roads, it is necessary to develop a product that is not only high performance but also inexpensive and excellent in scenery.

Furthermore, in the recent sidewalk space, it has evolved from barrier-free and aimed at a comfortable space for everyone, and the height of the sidewalk and the roadway has become almost the same. It has become a universal space where the sidewalks are not going up and down like in the past.

However, as a new problem, only Pokkori and the road curb jump out between the roadway and the sidewalk. This protruding curb is troublesome, and conversely, there are a series of accidents that stumbling on this curb.

In order to solve the above-mentioned problem, in claim 1, in the sidewalk lighting device, a plurality of LEDs, which are obtained by horizontally polarizing the light, are arranged on the road curb and are integrated in a housing. A sidewalk lighting fixture featuring

The sidewalk lighting fixture of the present invention is configured on the road curb because the metal pole is installed on the end of the conventional road and light is attached to the sidewalk surface from the lamp attached at a height of 3 to 5 meters. The sidewalk lighting was done in the form of hitting. Then, the attenuation of light was large and a large energy of 9 to 25 times was required.

  Because energy decays with the square of distance, there was no way to do it. However, with the recent revolution of lighting with LEDs, it has become possible to make bright lighting compact with extremely low power consumption.

As described above, in the present invention, lighting around the road curb, which is the nearest place of the necessary place, with a durable LED without a structural member such as a column, it is bright at a low price, Since the landscape can be maintained well, it is a very effective product.

It is a perspective view of the use condition which installed this invention sidewalk lighting fixture on the curb. It is the side view which installed this invention sidewalk lighting fixture on the curb. It is a perspective view of this invention sidewalk lighting fixture. It is a side view when this invention sidewalk illuminating device is comprised on the side surface of a concrete curb. It is a side view when the road surface on both sides of the curb is illuminated with the present invention sidewalk lighting device. It is a perspective view when a solar cell is comprised on the housing of this invention walkway lighting fixture.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a use state in which the sidewalk lighting device 1 of the present invention is installed on a curb 2. The LED4 light is diffused in the horizontal direction using a lens, etc., arranged side by side on the side of the housing, and mounted on the curb 2 that protrudes between the roadway and the sidewalk 7 on the sidewalk. 7 is illuminated. Although the installation interval at this time depends on the performance of the sidewalk lighting device 1, it is installed at intervals of about 1 to 5 meters.

FIG. 2 is a side view of the sidewalk lighting device 1 of the present invention installed on the curb 2. Thus, the sidewalk lighting device 1 of the present invention in which a plurality of LEDs 4 are loaded on the curb 2 is installed on the curb at an extremely low height of about 20 to 50 mm.

And by lighting the sidewalk 7 with a width of 1 to 4 to 5 meters, the pedestrians, bicycles, baby carriages, wheelchairs and other so-called traffic weak people pass the sidewalk 7, especially at night. It becomes a sidewalk space that is easy to walk, safe, inexpensive, high-class, and has a landscape that matches the surrounding environment.

FIG. 3 is a perspective view of the sidewalk lighting device 1 of the present invention. Four LEDs 4 in which light is diffused by a lens in the lateral direction are loaded side by side in a housing. Depending on the performance of each LED4, about 2 to 5 LEDs are used side by side. However, the number of LEDs 4 is comparable to the performance when using several LEDs, or one lens effect. Even if it has the ability to disperse light neatly in the horizontal direction, it only needs to have a technique that can be manufactured.

The housing 3 is manufactured by aluminum casting or aluminum die casting, but may be manufactured by a metal having higher corrosion resistance such as stainless steel.

The size of the housing 3 is appropriately between 20 mm and 50 mm in height, but it does not interfere with the thickness of the housing 3 even when it becomes as thick as 100 mm by adding various functions.

In addition, since the width of the sidewalk is 1 meter or 3 meters, it is advantageous that the angle at which light is emitted can be adjusted when the housing is mounted. When mounting on the curbstone 2, it is recommended to use an anchor bolt to fix it, or use a washer or wedge at that time, or make a screw hole in the housing and adjust the direction of light emission with a bolt or the like.

Further, the brightness of the LED 4 is assumed to be about 1 to 3 watts, and the case where the LED 4 illuminates the sidewalk with 4 watts to 12 watts is illustrated. This is an incandescent light bulb with very bright sidewalk lighting of about 40 to 80 watts. Since the number of LEDs 4 is plural, it may be two to ten. For example, a single LED 4 is a lens, etc., and has the same horizontal spread as when a plurality of LEDs are used. However, if it is possible to arrange a plurality of elements in the horizontal direction, it is easier to obtain a horizontal spread.

As for the power source, the commercial power source is useful because it has a small initial investment, but considering the long term, there is no problem even if the power source using the solar cell 6 is adopted. A voltage of 12 to 24 volts is desirable because it is compatible with LEDs and is unlikely to cause a major trouble in the event of an accident.

As described above, if the sidewalk 7 is illuminated from a high position, for example, a height of 5 meters, the light is attenuated to 1/25 when reaching the road surface. Even if it is illuminated from a high position with a 500 watt light bulb, it is attenuated to a brightness of 20 watts.

FIG. 4 is a side view when the sidewalk lighting device 1 of the present invention is configured on the side surface of the curb 2 made of concrete. A space having a size determined in advance at the time of manufacturing the concrete curb 2 is created, and the housing 3 is formed therein. At this time, it is attached with an adhesive or the like, but if the depth of the concrete of the curb 2 is kept wide, it will be better because it will be difficult to come out.

FIG. 5 is a side view when the road surface on both sides of the curb 2 is illuminated with the sidewalk lighting device 1 of the present invention. When illuminating both sides of the curb 2, it is preferable to use a housing having such a cross section. However, two side housings shown in FIG. 3 may be used to illuminate the left and right sidewalks 7 and the roadway.

These are also effective for lighting in particularly dangerous places such as near pedestrian crossings and stairs.

FIG. 6 is a perspective view when the solar cell 6 is constructed on the upper part of the housing of the sidewalk lighting device 1 of the present invention. If the solar cell 6 is not made quite large, long-time illumination is impossible. However, it is limited to short-time illumination, or the performance of the solar cell will remain as a possibility.
