DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device and a lighting window provided with a cleaning device driven by wind power or the like.

[0002]

2. Description of the Related Art The surface of a cover of a lighting device installed outdoors such as a street light or the surface of a daylighting window, which is exposed to the outside air, is exposed to the wind and rain, and various particles floating in the air such as dust, dust, particles contained in exhaust gas and the like. When such substances, bird droppings, spider webs, and the like adhere, they gradually become soiled, and the light transmittance gradually decreases.

For this reason, it is necessary to periodically clean the cover of the outdoor lighting device or the exposed surface of the lighting window. However, the number of outdoor lighting devices or daylighting windows is enormous, and they are often installed at high places. Therefore, it is extremely difficult to regularly clean such outdoor lighting devices or daylighting windows by human power. Therefore, the present situation is that cleaning is not performed so often once every several years. Street lamps are cleaned when the lamp is replaced. Recently, however, the technology of the lamp has been advanced, and a long-life lamp has been developed, and the cleaning interval has been increased.

Therefore, as a method of maintaining the transparency of the cover or the lighting window of the outdoor lighting device without adding cost and labor, it is conceivable to attach a cleaning device that operates continuously by using wind power. The conventional technology regarding lighting devices and daylighting windows equipped with such a cleaning device utilizing wind power is based on the idea that a windmill having a plurality of blades continuously rotates by receiving wind power, and the continuous rotating motion is wiped through a transmission. It is converted into the operation of the member.

[0005]

In a system in which the wiper member is operated by utilizing the continuous rotation of a wind turbine having a plurality of blades, the wind turbine moves excessively violently when a strong wind blows and is strong against a driving device. There is a problem in that a load is applied, and a transmission having a complicated structure needs to be incorporated in order to convert the high-speed continuous rotation of the wind turbine into an appropriate operation of the wipe member.

Accordingly, the present invention provides a lighting device with a cleaning device that is driven by wind power or the like that does not require excessively violent operation of a driving device even when a strong wind is blowing and that does not require the incorporation of a transmission having a complicated structure. It is an object to provide a lighting window with a device and a cleaning device.

[0007]

In order to solve the above-mentioned problems, an illumination device with a cleaning device according to the present invention is provided with a wind receiving member which can rotate when wind is applied to a wind receiving surface. And a wipe member connected to the wind receiving member and provided so as to operate integrally with the wind receiving member while being in contact with the cover of the lighting device.

[0008] With this configuration, when wind is blown against the wind receiving member, the wind receiving member rotates by applying wind pressure to the wind receiving surface, and the wipe member contacts the cover of the lighting device while the wipe member contacts the cover. It moves integrally with the wind receiving member.

The wind receiving member continues to rotate until the wind receiving surface faces the direction not receiving the wind pressure. However, once the wind receiving surface turns to the direction not receiving the wind pressure, the direction of the wind receiving member is changed unless the wind direction changes. Is fixed. Unlike the wind turbine, in which the blades continue to receive the wind pressure and continuously accelerate, the wind receiving member only accelerates until the wind receiving surface faces a direction not receiving the wind pressure, and the wind receiving member rotates slowly. Therefore, no burden is caused by the drive device operating excessively violently.
In addition, since the movement of the wind receiving member is gentle, the wind receiving member and the wipe member can be connected without using a transmission, for example, by connecting the wind receiving member and the wipe member with a shaft. Become.

The lighting device with a cleaning device according to the present invention is preferably characterized in that the lighting device includes a vertically movable weight that is interlocked with the wind receiving member and the wipe member. According to such a configuration, the gravity of the weight can be used as the driving force of the cleaning device in addition to the wind pressure applied to the wind receiving surface of the wind receiving member. That is, when there is no wind, the wind receiving member is oriented so that the weight is at the lowest position in its movable range, but when the wind blows, the wind receiving member rotates due to the wind pressure applied to the wind receiving surface, and the weight is also reduced. Works with the wind receiving member. When the force of the wind pressure applied to the wind receiving surface becomes weaker than the gravity of the weight due to the stopping or weakening of the wind, the force of the wind pressure applied to the wind receiving surface of the wind receiving member transmitted to the weight through a coupling machine such as a shaft A restoring force combined with the gravity of the weight acts. The restoring force causes the weight to perform a pendulum motion, and the wipe member moves while being in contact with the weight and in contact with the surface of the cover.

Furthermore, in the illumination device with a cleaning device of the present invention, it is preferable that the wind receiving member is attached to the wipe member. With this configuration, the structure of the cleaning device becomes simpler.

In order to solve the above-mentioned problems, a daylighting window with a cleaning device according to the present invention includes a daylighting window, a wind receiving member rotatable when wind is received on a wind receiving surface, and a wind receiving member connected to the wind receiving member. And a wipe member provided so as to operate integrally with the wind receiving member while being in contact with the window surface.

With this configuration, when wind is blown against the wind receiving member, wind pressure is applied to the wind receiving surface, so that the wind receiving member rotates, and the wind receiving member contacts the window surface while the wipe member contacts the window surface. It moves integrally with the member.

The wind receiving member continues to rotate until the wind receiving surface faces a direction not receiving the wind pressure. However, once the wind receiving surface faces the direction not receiving the wind pressure, the direction of the wind receiving member is changed as long as the wind direction does not change. Is fixed. Unlike the wind turbine, in which the blades continue to receive the wind pressure and continuously accelerate, the wind receiving member only accelerates until the wind receiving surface faces a direction not receiving the wind pressure, and the wind receiving member rotates slowly. Therefore, no burden is caused by the drive device operating excessively violently.
In addition, since the movement of the wind receiving member is gentle, the wind receiving member and the wipe member can be connected without using a transmission, for example, by connecting the wind receiving member and the wipe member with a shaft. Become.

In the daylighting window with the cleaning device of the present invention,
It is preferable to provide a vertically movable weight interlocking with the wind receiving member and the wipe member. According to such a configuration, the gravity of the weight can be used as the driving force of the cleaning device in addition to the wind pressure applied to the wind receiving surface of the wind receiving member. That is, when there is no wind, the wind receiving member is oriented so that the weight is at the lowest position in its movable range, but when the wind blows, the wind receiving member rotates due to the wind pressure applied to the wind receiving surface, and the weight is also reduced. Works with the wind receiving member. When the force of the wind pressure applied to the wind receiving surface becomes weaker than the gravity of the weight due to the stopping or weakening of the wind, the force of the wind pressure applied to the wind receiving surface of the wind receiving member transmitted to the weight through a coupling machine such as a shaft A restoring force combined with the gravity of the weight acts. The restoring force causes the weight to perform a pendulum motion, and the wipe member moves while being in contact with the weight and in contact with the surface of the window.

Further, in the daylighting window with a cleaning device of the present invention, it is preferable that the wind receiving member is attached to the wipe member. With this configuration,
The structure of the cleaning device becomes simpler.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a lighting device with a cleaning device and a lighting window with a cleaning device according to the present invention will be described below in detail with reference to the accompanying drawings. The same elements will be denoted by the same reference symbols, without redundant description.

FIG. 1 is a perspective view showing an embodiment of a lighting device with a cleaning device according to the first embodiment of the present invention.
FIG. 2 is a partial cross-sectional view of the illumination device with a cleaning device shown in FIG. The street light 100 exemplified here has a columnar lamp cover attached in a vertical direction. A post 102, which is a lamp post inside the street light main body, is fixedly attached to a street light mounting pipe 101, which is a post of the street light main body, by a pipe mounting bracket 103, and a lamp 104 having a luminous body inside at the tip of the post 102 Is attached. A bottom cap 105 for fixing a probe, which will be described later, is attached to an upper portion of the cylindrical surface of the support 102, and a cylindrical probe 106 is fixed on the bottom cap 105. The probe 106 is made of a transparent material, through which light emitted by the luminous body is emitted to the outside. The upper portion of the probe 106 is covered with a head cap 107, and the probe 106, the bottom cap 105 and the head cap 107 constitute a lamp cover.

Pipe fitting 103 and bottom cap 1
05, the rotating ring 108 surrounds the support 102.
Is arranged. A bearing 109 is incorporated between the support 102 and the rotating ring 108, and the rotating ring 10
Numeral 8 rotates smoothly around the support 102. By fixing a wind receiving member and a wipe member to be described later to the rotating ring 108, the wind receiving member and the wipe member are integrally linked.

Wiper cover 1 for holding brush
10 is the probe 1 by the wiper cover attaching portion 111.
06 is fixedly attached to the rotating ring 108 so as to be parallel to the cylindrical surface outside. Wiper cover 11
At 0, a brush 112 is attached so as to be in contact with the outer cylindrical surface of the lamp cover. A wipe member is constituted by the wiper cover 110 and the brush 112. The wipe member includes a wind receiving member 113 having a wind receiving surface.
Are attached so that the wind receiving surface is a plane perpendicular to the direction of movement of the wipe member.

The street light 100 having the above configuration
Is assumed to be installed on roads, and the outer surface of the lamp cover is exposed to the weather, and various substances floating in the air, such as dust, dust, particles contained in exhaust gas, and bird droppings. There is a concern that the spider's web and the like will gradually become dirty due to the adhesion. The exposed surface of the probe 106 is dirty,
When the light transmittance is reduced, the efficiency of illumination is reduced.

However, in the street light 100, the wind receiving member 113 rotates so that the wind receiving surface of the wind receiving member 113 faces the direction in which the wind resistance does not receive the wind resistance, that is, the leeward direction.
12 also receives the wind receiving member 1 through the rotating motion of the rotating ring 108.
Since the brush 112 moves integrally on the cylindrical surface outside the lamp cover while being integrally connected to the lamp cover 13, dirt attached to the surface of the lamp cover is removed by the movement of the brush 112.

In the street light 100, even when a strong wind is blowing, once the wind receiving surface of the wind receiving member 113 faces the leeward direction, the direction of the wind receiving surface of the wind receiving member 113 is maintained unless the wind direction changes. Since it is fixed in that direction, the cleaning device does not run too hard.

On the other hand, since the wind blows from the street light 100 in all directions, the rotating ring 108 also rotates through all angles so that the wind receiving surface of the wind receiving member 113 faces in all directions. The range in which 112 moves while being in contact with the outer cylindrical surface of the lamp cover also covers the entire outer cylindrical surface of the lamp cover.

Since the structure of the street light 100 is simple, the production cost is lower than that of a lighting device with a cleaning device using a windmill, and the cleaning device is inconspicuous because the cleaning device is inconspicuous. Does not hurt.

7 and the probe 206 and the bottom cap 2
05 and the head cap 207 constitute a lamp cover.

Pipe fitting 203 and bottom cap 2

The wipe member also moves along the cylindrical surface outside the lamp cover by being integrally connected to the rotating ring 208. That is, the wipe member operates not only by the rotational movement of the rotating ring 208 according to the change in the wind direction, but also by the pendulum movement of the rotating ring 208 when the wind stops or weakens. The dirt attached to the outer cylindrical surface of the lamp cover is removed by the movement of the wipe member.

In the above street light 200, the rotating ring 208
