Description

  The present invention relates to a lighting device of an independent power source equipped with a solar battery panel and a storage battery, and more specifically, a thin type that can be detachably attached to a safety fence such as a pedestrian bridge and a bridge or a road fence. The present invention relates to an independent power supply type lighting device.

  Conventionally, as an illuminating device for illuminating a pedestrian bridge, a bridge, a road, etc., it is common to employ an illuminating lamp facility having a configuration in which a lamp is provided at the upper end of a support column. In this illuminating lamp facility, fluorescent lamps, mercury lamps, various types of discharge lamps are used as light sources, and commercial power supplies are used as power sources.

  However, in order to adopt the above illuminating lamp equipment, a space is required for installing a column that supports the lamp, and concrete foundation work and an illuminating lamp for stably installing the column are used as a commercial power source. There is a problem that electrical work for connection is required, and the facility becomes very large. In general, fluorescent lamps, mercury lamps, and various types of discharge lamps have a life span of about 8,000 hours to about 20,000 hours. Therefore, when the above-mentioned lighting equipment is used, the life is about 1 year to about 3 years. There is also a problem in that it is necessary to replace it every degree, and much labor is required for maintenance.

  Furthermore, the wavelength of light emitted from a fluorescent lamp or mercury lamp includes the wavelength in the ultraviolet region that collects insects. There was also a problem that crowded and became uncomfortable for passers-by. In addition, when the above illuminating lamp equipment is adopted, the function of the illuminating lamp equipment may not be demonstrated due to a power failure in the case of a disaster or when an accident occurs in the commercial power wiring network. There are also problems such as using a large amount of running costs and increasing the burden on the environment.

  In order to solve many of these problems, a solar panel and a storage battery provide an independent power source, and as a light source, a low-power consumption and long-life high-intensity LED (Light-Emitting Diode) The illuminating lamp equipment having a configuration in which is adopted is becoming widespread (see, for example, JP-A-2005-235513 (Patent Document 1), JP-A-2008-192529 (Patent Document 2), etc.). By adopting this kind of lighting equipment, it is an independent power supply type that does not use a commercial power supply, so that the above-mentioned electrical work is unnecessary and the advantage that it can be used in an emergency such as a disaster. In addition to the benefits of eliminating the need for running costs, the benefits of low environmental impact, and the use of high-brightness LEDs with low power consumption and a long life as a light source, The merit that insects do not gather will be obtained.

  Also, in recent years, some lighting lamps have been widely used that do not have lamps provided on the columns as described above, but have built-in lamps directly into safety fences such as pedestrian bridges and bridges, road fences, etc. (See Kaihei 8-246426 (Patent Document 3), Utility Model Registration No. 3124041 (Patent Document 4), etc.). When this type of illuminating lamp equipment is adopted, although there is a merit that the space for installing the support and the concrete foundation work are not required, commercial power is still used as the power source. The problem has not been solved sufficiently.

JP 2005-235513 A JP 2008-192529 A JP-A-8-246426 Utility Model Registration No. 3124041

  As described above, when a solar panel and a storage battery are provided, an independent power source is used, and a lighting device having a configuration in which a high-brightness LED with low power consumption and long life is adopted as a light source. Can obtain advantageous effects in a great many respects compared with the case of using conventional illumination lamp equipment. However, even in such an illuminating lamp facility, since the structure in which the lamp is provided on the support is adopted, there is still a problem that a space for providing the support and a concrete foundation work are required.

  In order to solve this problem, it is effective to install an independent power supply type lighting device on existing equipment such as safety fences such as pedestrian bridges and bridges and road fences, but this has not been realized for the following reasons. Not reached.

  That is, in order to attach the lighting device to a safety fence such as a pedestrian bridge and a bridge, a road fence, or the like, it is essential to reduce the size of the lighting device. However, in order to ensure a sufficient illumination function, it is necessary to ensure a sufficiently wide illumination range illuminated by the illumination device, so that any shape can be used as long as it is small. is not. Therefore, the outer shape of the lighting device is necessarily configured to be thin so that it can be easily attached to the fence and a sufficient lighting range can be secured.

  Here, in order to make an independent power supply type lighting device, it is necessary to provide a storage battery in the lighting device, but when the storage battery is generally used at a temperature higher than normal temperature, its life is used at normal temperature. There is a problem that it is significantly reduced compared to the case. On the other hand, in order to make an independent power supply type lighting device, it is necessary to ensure that the lamp emits light for a long time at night, so the solar cell panel as described above is used so as to ensure a sufficient amount of power generation. Is preferably performed. However, in order to efficiently generate power, a black, dark blue, or dark blue antireflection film is generally formed on the surface of the solar cell panel. Therefore, the temperature of the solar cell panel in the daytime is In general, the temperature is about 20 to 30 ° C. higher than the temperature.

  Therefore, when the solar battery panel and the storage battery are arranged close to each other in order to reduce the thickness of the lighting device, the heat of the solar battery panel that has become a high temperature state by receiving sunlight is transferred to the storage battery. As a result, there is a problem that the life of the above-described storage battery as a component is significantly reduced, and as a result, the product life of the lighting device is significantly shortened. In addition to the above-described solar battery panel and storage battery, the lighting device includes a lighting unit including a lamp, and a circuit unit in which a connection circuit that is electrically connected to the solar battery panel, the storage battery, and the lighting unit is formed. However, when these lighting units and circuit units are exposed to a high temperature environment, there is a problem that their deterioration progresses quickly. This leads to a problem that the product life is greatly shortened.

  Thus, in order to reduce the thickness of an independent power supply type lighting device including a solar cell panel and a storage battery, there is a problem that it is difficult to ensure a long product life due to thermal influence. In addition, it avoids that the thermal influence mentioned above arises by adopting the structure which comprises a solar cell panel and a storage battery separately, and installs this individually on a safety fence such as a pedestrian bridge and a bridge or a road fence. However, there is a problem that the installation work becomes complicated and the wiring for electrically connecting the solar cell panel and the storage battery configured separately is not possible. It will be exposed to the outside and will cause problems such as detracting from aesthetics, and cannot always be said to be an effective solution. In addition, when the solar battery panel and the storage battery are configured separately, there arises a problem that they cannot be removed from the fence and used in an emergency such as a disaster.

It is to provide an independent power supply type lighting device provided with a detachable attachment of the independent power supply type lighting device to a safety fence such as a pedestrian bridge and a bridge or a road fence.

Further, by attaching the lighting device 1 to the vertical beam 101, no power generation loss due to snow accumulation occurs, and the use in snowy areas is also possible.

  The mounting arm 13 provided on the apparatus main body 10 described above tilts the apparatus main body 10 when the lighting apparatus 1 is used on a floor surface or the ground surface without using the lighting apparatus 1 attached to a fence. It becomes a support arm to support. Therefore, by using the mounting arm 13 as a support arm and installing the solar cell panel 20 in the direction in which the sun is positioned, efficient power generation is possible and the mounting arm 13 is used as a support arm. By installing the back surface of the apparatus main body 10 toward the object to be illuminated, it becomes possible to perform efficient illumination.

  By using the illumination device 1 as in the present embodiment described above, the above-described internal components are bonded and fixed to the back surface of the solar cell panel 20 via the sheet-like adhesive member 60 having high heat insulating properties. It becomes possible to assemble the apparatus main body 10 while suppressing the influence of heat generated in the solar cell panel 20. Therefore, even when the solar cell panel 20 and other internal components are integrally assembled to the apparatus main body 10 without being configured separately, the apparatus main body 10 is configured to be significantly thinner than conventional ones. can do. Therefore, as described above, the lighting device 1 can be easily attached to a safety fence such as a pedestrian bridge and a bridge, a road fence, or the like.

  Moreover, by using the illumination device 1 as in the present embodiment described above, the mounting angle of the mounting arm 13 with respect to the device body 10 can be adjusted to an arbitrary angle. Therefore, by adjusting the attachment angle, the apparatus main body 10 can be attached to the vertical bars 101 having various thicknesses or shapes within a predetermined range. As a result, it can be set as the illuminating device 1 which can be easily attached with respect to a fence regardless of the shape of a fence.

  Therefore, by adopting the lighting device 1 having the above-described configuration, it is not necessary to provide a support post separately from safety fences such as pedestrian bridges and bridges, road fences, etc. Since it is a power supply type, there is no need to connect to a commercial power source, and the effect of eliminating the need for electrical work can be obtained. In addition, by adopting the lighting device 1 having the above configuration, since it is an independent power supply type, an effect that the running cost is unnecessary, an effect that the load on the environment is small, an accident occurs in a disaster or in the commercial power wiring network. Even in the case of an effect, the effect as a function of illumination can be obtained. In addition, by using the lighting device 1 having the above-described configuration, it becomes possible to remove the lighting device 1 from the fence and carry it for use in an emergency such as a disaster, thereby preventing the occurrence of a secondary disaster. It is also possible to obtain the effect and the effect that it can be used for the victims.

  In addition, in the illumination device 1 configured as described above, the high-brightness LED 53 with low power consumption and long life is adopted as the light source, and therefore the period until the luminance is reduced to 70% of the initial value is also about 40,000 hours. In addition, the brightness is gradually reduced without immediately turning off or blinking like a fluorescent lamp or a mercury lamp. Depending on the situation, the replacement work of the high-intensity LED 53 is about 7 to 10 years. The effect which becomes unnecessary for a year is also acquired. Further, by using the high-intensity LED 53 as a light source, it is possible to obtain an effect that insects do not gather.

  Moreover, in the lighting device 1 having the above-described configuration, the forced lighting switch 12b is provided in the device body 10, so that it is possible to perform the lighting operation regardless of the brightness of the surroundings when necessary. This is also secured for convenience.

  As described above, by adopting the illumination device 1 according to the present embodiment, almost all of the drawbacks of the conventional illumination lamp equipment are solved.

  In the present embodiment described above, in addition to the storage battery, other internal components are also exemplified and fixed on the back surface of the solar cell panel using a highly heat-insulating sheet-like adhesive member. However, for these other components, such an assembly structure does not necessarily have to be adopted, and when the thickness can be made thin, it is fixed to the frame or the support member by screws or the like. Also good.
