DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a street light, and more particularly to a solar power street light that uses a light emitting diode as a light source and illuminates with electric energy stored by a solar cell.

[0002]

2. Description of the Related Art Conventionally, street lights are provided on roads and parks such as city areas so that they can pass safely at night. The street lamp is supported by embedding the lower end of the pole in the ground, bending the upper end horizontally and projecting to the road side, and attaching a light source such as a fluorescent lamp or a mercury lamp to the end, or vertically Generally, a light source such as a fluorescent lamp or a mercury lamp is attached to the upper end of the pole to be erected.

[0003] Such a street light is usually supplied with electric energy from a commercial power supply by wiring from a telephone pole planted along a road, and is used to illuminate a road or park with a light source such as a fluorescent lamp or a mercury lamp. Lighting is used to ensure the safety of pedestrians.

On the other hand, in inconvenient places such as mountain roads, coastal roads and agricultural roads where electric power lines are not wired and commercial power cannot reach, electric energy generated by natural energy such as solar power or wind power is stored in a storage battery. The electric energy is supplied to a ready-made light source such as a fluorescent lamp or a mercury lamp and used as lighting.

[0005]

However, the conventional street lamps using a fluorescent lamp, a mercury lamp or the like as a light source are comparatively large, and as a result, not only the protective equipment is inevitably increased, which increases the cost but also increases the installation cost. In places where there are trees and signboards, it may not be able to be installed because it is in the way,
The installation place was sometimes restricted.

Further, the light source of a fluorescent lamp or a mercury lamp has a short life and requires a large amount of maintenance for replacement, which requires a lot of trouble in handling, consumes a large amount of power, and is uneconomical. In addition, a light source having only a ready-made brightness cannot provide an appropriate amount of light that requires more light.

[0007] In addition, since conventional street lights use a commercial power supply as a power source, once a power failure occurs due to a break in a power pole due to a natural disaster such as a typhoon or an earthquake, or a cut in a transmission line, it takes too much time to recover, and the lighting is turned on. There was a problem that it would not last for a long time, and it would be useless during disaster prevention.

Further, recently, since the townscape is emphasized, the streets and the like are being beautified actively, and the towns are receiving power from the transmission lines of the conventional telephone poles through the service lines. There was a problem that the street light impaired aesthetics. In particular, it was not suitable for places where the scenery was important, such as gardens, parks, and promenades.

On the other hand, in the case of photovoltaic power generation, a solar cell panel is usually mounted on a pole, and the size of the photovoltaic cell is limited. A street lamp using a fluorescent lamp or a mercury lamp as a light source, which consumes a large amount of power, has a problem that the storage battery is easily discharged and cannot be used effectively.

The present invention has been developed with the object of solving the above problems, and has an extremely simple structure, low power consumption, a semi-permanent life, and economical maintenance-free operation. It is an object of the present invention to provide a solar power street light which is high in value and can also be used as a disaster prevention light or a guide light in the event of a disaster.

[0011]

However, the photo sensor 14
In the case of wearing, when the light of turning off is detected by the photo sensor 14, the function of the photo sensor 14 is activated preferentially so that the light can be turned off even within the lighting time. Then, from the next day, the light is automatically turned on and off every 24 hours based on the data in which the state is stored.

The use state of the first embodiment configured as described above will be described together with the function and effect. If this solar power street light is installed and installed on a sidewalk, a park, a plaza, a parking lot, etc. The light emitting diode is illuminated and brightened. Since the white light emitting diode 5 is used as the light source, the same illuminance as that of a fluorescent lamp can be obtained with low power, and the service life is semi-permanent, so that maintenance is unnecessary and economical. Further, the light quantity can be handled by the number of the white light emitting diodes 5 according to the application, and if the distance from the light source and the required light quantity are known, the number can be calculated inevitably.

Since the casing body 1 is relatively low in height, for example, if it is used as an illumination light such as an approach light or a garden light, it can be blended into a landscape at a low position and illuminate the foot, and the outer surface can be made natural. Since it is made of cherry granite 2, its appearance is beautiful, and it matches the environment if used in places where the natural environment is important, such as gardens, parks, and promenades.

Further, the inside of the casing body 1 is divided into three stages of upper, middle and lower chambers, and since the lower chamber is formed in a non-accommodating space, it is assumed that water enters due to rain or snow falling. Since the storage battery 8 and the control device 9 that affect the lighting are installed in the middle room and the upper room, illumination can be performed without any adverse effect.

Another difference is that a short pole 15 is joined and integrated on the upper surface of the casing body 1 and an inclined surface 1a of about 45 degrees is provided on the uppermost portion of the pole 15, and a large number of suns are provided on the inclined surface 1a. The battery 3 is fixed, and a white light emitting diode 5 serving as a light source is attached below the battery 3.

The street light configured as described above is turned on by the same operation as in the first embodiment, and is installed in a road, a park, a plaza, a parking lot, or the like. In addition to providing the same function and effect, since the positions of the solar cell 3 and the white light emitting diode 5, which are the required reference heights for disaster prevention lighting, are 2 m or more in height, they can be used as disaster prevention lighting or guide lights during natural disasters. What can be used.
