Description

Lamp with automatic cleaning

The present invention relates to a lamp having an automatic cleaning function, and in particular, the light cover is rotated in contact with the brush to remove dust on the surface to prevent phenomena such as shadows generated by the brush operation, dust caused by the rotation without the electric structure The present invention relates to a technology that can be easily removed to simplify the structure, facilitate maintenance, and achieve energy savings.

In general, a street lamp or an indoor or outdoor lamp has a structure in which a light emitting lamp is accommodated in a light cover, and light emitted from an internal light emitting lamp is irradiated through a light transmitting plate of the light cover.

In such a lamp, when the light is used for a long time, dust and the like are buried on the entire surface of the floodlight plate, thereby reducing the light emission efficiency of the light emitted from the light emitting lamp.

Therefore, the surface of the floodlight is periodically cleaned, but in the past, since the cleaning of the light cover is performed manually, the work is cumbersome, and in the case of a street lamp, there is a problem that the risk of a fall accident or a traffic accident is accompanied by a height of work.

Recently, a technique for automatically cleaning the dust on the outer surface of the floodlight of the streetlight has been proposed, all the prior art is a method of sweeping the dust on the surface of the floodlight by rotating the brush, etc. in the form of a car wiper using an electric motor.

However, the prior art has a disadvantage in that the power consumption is large and the risk of failure is great as it has the electric drive structure.

In addition, since the brush sweeps the surface of the floodlight while rotating the brush, when the brush is rotated in the process of illuminating the light, a shadow of the brush is generated, which adversely affects the light irradiation efficiency.

In addition, the prior art simply removes the dust on the outer surface of the floodlight plate, so that when the dust is used for a long time, the dust accumulated inside the floodlight cover cannot be removed, thus adversely affecting light transmission efficiency.

As a result, the worker has to manually clean the inside of the light cover to remove the dust.

The present invention has been proposed to solve the problems of the prior art,

By enabling the automatic dust removal on the surface of the light cover without power supply, the structure is simplified compared to the existing electric method to reduce the failure rate and provide a light having an automatic cleaning function that can have an energy saving effect.

In addition, it is possible to remove foreign substances on the outer surface and inner surface of the light cover at the same time to improve the cleaning efficiency, as well as to have a light with an automatic cleaning function to prevent the trouble of having to clean the inside of the light cover by hand. To provide.

In addition, to provide a light having an automatic cleaning function that can prevent the generation of shadows by the operation of the brush.

Hereinafter, specific configurations and effects of the present invention will be described based on the embodiments shown in the drawings.

Electric light having a cleaning function of the present invention, as shown in [FIG. 1] to [FIG. 5], the fixed installation unit 100 and the light cover 200, the fixing frame 510, the rotation guide unit 400 and dust It is configured to include a removal unit 500.

First, the fixed installation unit 100 serves as a fixed installation function of the present invention. As shown in the drawing, when the application field of the present invention is a street lamp, the fixed installation unit 100 becomes a street lamp post.

And although not shown in the drawings, when the present invention is implemented as an indoor light fixture is a structure that can be fixed to the wall or ceiling to install all the components, including the lamp cover 200 to be described later.

As such, the fixed installation unit 100 is not limited to the shape of the post as shown in the drawings can be variously implemented according to the application of the present invention.

The lamp cover 200 is installed in the fixed installation unit 100.

The lamp cover 200 serves as an external casing of the lamp and a function for installing the light emitting lamp 300 and cleaning its own surface as the name suggests. The fixing rod 210, the rotating body 220, and the floodlight cover ( 230).

Among them, the fixing rod 210 serves as a connection medium between the lamp cover 200 and the fixed installation unit 100 and an installation function such as a socket 310. The fixed rod 210 has a hollow tube shape having a predetermined length and is fixed at one end. The end of the installation portion 100 is installed in the inserted state.

A bearing (B) for inducing a smooth rotation of the light cover 200 is installed on the circumferential surface of the section surrounding the fixed installation portion of the fixing rod 210.

Rotating body 220 which is another element constituting the light cover 200 together with the fixing rod 210 to the actual rotation function of the light cover 200, the hollow tube-shaped rotary tube 222 and rotary tube It is composed of a connecting enclosure 224 formed at the front end of the (222).

Among them, the rotary tube 222 is installed in a state in which the bearing (B) is wrapped around, that is, the end of the fixed installation portion 100 and the fixed rod 210 and the bearing (B) is inserted.

At this time, the fixed rod 210 is made longer than the rotary tube 222 so that the rear end of the fixed rod 210 to the outside through the rear end of the rotary tube 222 when the fixed rod 210 is inserted into the rotary tube 222. The exposed state.

By this structure, the rotary tube 222 is in a state capable of rotating along the circumference of the fixed rod 210 via the bearing (B) as a medium.

In addition, the connection housing 224 formed on the front side of the rotary tube 222 has a function of installing the rotary induction part 400 to be described later and a connection function with the floodlight cover 230 to be described later, and the front part has an open housing shape. The rear end is made in the form that the diameter is extended toward the front side in a state connected integrally with the front edge of the rotary tube 222.

In addition, a first fastening piece 225 for fixing and coupling with the floodlight cover 230 is formed at the front edge of the connection enclosure 224, and the fastening rail 226 for fastening with the floodlight cover 230 is also formed on the circumferential surface thereof. Is formed.

At this time, the fastening rail 226 is formed in a curved shape so as not to be separated in a straight direction when the fastening protrusion described later.

The floodlight cover 230 constituting the lamp cover 200 together with the rotating body 220 serves as a floodlight for external irradiation of light emitted from the light emitting lamp in addition to the protection function of the light emitting lamp 300. The part is an open cylindrical structure and is made of a transparent or translucent transparent material.

At this time, the outer diameter of the rear end of the floodlight cover 230 is equal to or less than the inner diameter of the front end of the connection enclosure 224 so that the rear end of the floodlight cover can be fitted into the front end of the connection enclosure.

The floodlight cover 230 has a second fastening piece having the same shape as the first fastening piece 225 of the connection enclosure 224 at a point facing the first fastening piece 225 of the connection enclosure 224 of the rear edge. 232 is projected in a facing state.

In addition, fastening protrusions 234 for fastening with the fastening rails 226 of the connection enclosure 224 are formed at both sides of the circumferential surface of the floodlight cover 230.

Due to this structure, the floodlight cover 230 has a rear end fitted into the front end of the connection housing 224, and in this process, the fastening protrusion 234 of the floodlight cover 230 is a fastening rail 226 of the connection housing 224. As shown in FIG. 1, the floodlight cover 230 and the connection enclosure 224 are primarily fastened.

In this case, as described above, the fastening rail 226 is formed in a curved shape, and thus, even if the floodlight cover 230 is pulled out in a straight direction toward the front, the coupling rail 226 is not separated from the connection enclosure 224.

At the same time, the second fastening piece 232 of the floodlight cover 230 is in a state facing the first fastening piece 225 of the connection enclosure 224 and in this state, the first fastening piece 225 with a separate bolt (B1). ) And the second fastening piece 232 are simultaneously fastened and fixedly installed while the shaking of the floodlight cover 230 is completely blocked.

By the structure described above, the rotating body 220 and the floodlight cover 230 are in a state capable of being rotatable around the fixed rod 210.

The light emitting lamp 300 and the socket 310 and the reflection shade 320 are installed inside the lamp cover 200 installed as described above. First, the socket 310 is installed at the front end of the fixing rod 210 and the socket The front end portion is connected to the light emitting lamp, and the reflection shade 320 is fixed to the upper portion of the light emitting lamp 300.

The structure and function of the light emitting lamp, the socket and the reflector 320 are generally known, and thus, further description thereof will be omitted.

In addition to the light cover 200, the rotation induction part 400 is further installed.

The rotation guide unit 400 serves to induce the automatic rotation of the light cover 200 by transmitting wind power to the light cover 200, made of a plurality of wings and each wing 410 is connected to one end of the housing ( 224 is formed to protrude toward the outside in a state connected to the circumferential surface and is installed in a circular array with a predetermined interval.

At this time, the wings are bent at a certain angle to the upper and lower ends so that the wind can be applied over the entire area regardless of the direction of the wind.

For reference, the blade-shaped rotation guide unit 400 may be processed in a groove shape on the circumferential surface of the connection enclosure 224 as shown in FIG.

In this case, since the wings do not protrude to the outside, the overall volume is reduced, and the vane is prevented from being damaged.

When the wind induction of the wing shape rotation guide 400 is installed in each of the wings 410 when the wind blows in the left and right direction of the light cover 200, the wind power is transmitted to the light cover to rotate the entire light cover It has a structure that is possible.

The dust cover 500 is further installed on the light cover 200 installed up to the rotation induction part.

The dust removing unit 500 serves to remove dust and the like buried on the inner and outer surfaces of the light cover 200, and again, the fixing frame 510, the first removing unit 520, and the second removing unit 530. It is configured to include).

First, the fixing frame 510 is a fixed installation function of the first removal unit 520 to be described later, the rod shape having a certain length and the rear end of the rotating tube 220 of the rotating body 220 of the fixing rod 210 It is fixedly connected on the section protruding to the outside from the rear end.

And in this state after being discharged toward the front side a certain section is positioned in a horizontal state with the upper surface of the light cover (200).

For reference, the fixed frame 510 may be fixedly connected to the fixed installation unit 100 instead of the fixed rod, and connected to the fixed rod 210 as shown in the drawing to set one, and then simply fix the fixed installation unit 100. By allowing the rod to be installed in the form of a rod, the entire installation structure can be simplified.

At this time, the fixing frame 510 is not located on the top of the light cover 200, but as seen from the front as seen from the front of the floodlight cover 230 in the direction obliquely upward from the center point of the light cover according to the light cover ( The contact efficiency between the surface and the first brush 524 described later is improved.

The first removal unit 520 serves to remove dust and the like on the outer surface of the light cover 200, and is divided into a first spring 522 and a first brush 524.

The first spring 522 serves to guide the free movement of the first brush 524 in the process of removing surface dust, as well as the connection function between the first brush 524 and the fixed frame 510 which will be described later.

The first spring 522 is fixedly connected to the upper end of the fixing frame 510 in a state positioned at the front and rear ends of the section positioned horizontally with the floodlight cover 230 of the fixing frame 510.

In addition, the first brush 524 substantially functions to wash the outer surface of the floodlight cover 230, and has a rod shape having a predetermined length as a whole and a brush hair formed on the circumferential surface.

The first brush 524 is installed with both ends connected to lower ends of the respective first springs 522.

At this time, the brush hair of the first brush 524 is formed in the shape of a thread along the longitudinal direction of the first brush 524, so that the entire first brush 524 is in one direction during the dust removal process on the surface of the floodlight cover 230. Allow it to be moved.

As described above, since the fixed frame 510 is positioned to be inclined upwardly from the center point of the floodlight cover, the first brush 524 is also biased toward the upward oblique direction from the center point of the floodlight cover 230. Located in the state, one side point in this state is in contact with the surface of the floodlight cover 230.

As such, as the first brush 524 is positioned at the diagonally biased position, unlike the case where the first brush 524 is positioned at the top of the floodlight cover 230, the first brush is lifted in the process of rotating the floodlight cover. Since the lifting phenomenon is not generated, it is possible to maintain a stable contact with the floodlight cover.

The second remover 530 constituting the dust remover 500 together with the first remover 520 serves to remove dust, etc., deposited on the inner surface of the floodlight cover 230. It is divided into two springs 532 and the second brush (534).

The second spring 532 serves to connect the second brush 534, which will be described later, to the reflector 320, to induce the free movement and return of the second brush 534 during the dust removal process. do.

The first spring 522 is positioned at the front and rear ends of one side lower edge of the reflection shade 320 in a state located inside the floodlight cover 230 and each upper end is fixedly connected to the edge of the reflection shade 320.

In addition, the second brush 534 serves to clean the inner surface of the floodlight cover 230, and like the first brush 524, has a rod shape having a predetermined length as a whole, and has a brush hair formed on the circumferential surface thereof.

The second brush 534 is installed with both ends connected to the lower ends of the respective second springs 532.

At this time, the brush hairs of the second brush 534 are also formed in the shape of a thread along the length direction of the second brush 534, so that the entire second brush 534 is one side in the process of removing dust from the inner surface of the floodlight cover 230. To be moved.

In addition, since the second spring 532 is installed in a state inclined to one side of the reflection shade as described above, the second brush 534 is also positioned at a point diagonally downward from the center point of the floodlight cover 230. In this state, one side point is brought into contact with the inner surface of the floodlight cover 230.

As such, the second brush 534 is not positioned on the innermost bottom of the floodlight cover, but is located at an oblique direction, so that a high contact efficiency between the second brush 534 and the surface of the floodlight cover during rotation of the floodlight cover is obtained. do.

For reference, in the present exemplary embodiment, the dust removing unit is divided into the first removing unit 520 and the second removing unit 530 to remove dust on the inner and outer surfaces of the floodlight cover 230 at the same time. If the gap sealing between the 230 and the rotating body 220 is perfect and there is little possibility of the inflow of dust, the second removing unit 530 may be omitted.

Hereinafter will be described the operation of the present invention by this configuration and the unique effects generated in the process.

Usually, the light emitted from the internal light emitting lamp is irradiated to the outside after transmitting the floodlight cover.

When implemented in the form of a street lamp, as shown in FIG. 3, the wind is blown in a direction perpendicular to the driving direction of the vehicle, that is, the longitudinal direction of the light cover.

Because of this, the wind power of the wind is acting on each wing 410 constituting the rotation induction unit 400, the rotation body 220 of the light cover 200 eventually along the direction of the wind around the fixing rod 210 Will rotate.

As the rotating body 220 is rotated as described above, the floodlight cover 230 connected thereto also rotates, and the outer surface and the inner surface of the floodlight cover are in contact with the first brush 524 and the second brush 534, respectively. Since the transparent cover 230 is rotated, the dust on the outer inner surface of the transparent cover is swept away by the first brush 524 and the second brush 534.

That is, the present invention is operated in a form in which the surface is swept by the brush while rotating the floodlight cover in a fixed state, unlike the prior art that wipes the surface of the floodlight plate while the brush is rotated.

Since the dust is removed while the position of the brush is fixed in this way, even if the street light is being illuminated, the brush is fixed so that the shadow is repeatedly generated by the brush operation.

In addition, as described above, since the first brush 524 and the second brush 534 are positioned at an oblique direction, the shadows of the first brush 524 and the second brush 534 during the irradiation of the street light Will not occur.

And as described above, since the brush hairs of the first brush 524 and the second brush 534 are formed in a spiral shape, each brush is moved in a linear direction toward the front or the rear in the process of rotating the floodlight cover. In the first spring 522 and the second spring 532 is tensioned.

Then, when each brush is linearly moved to a specific point, the brush is automatically returned to its original position by the elastic force of the spring, and this process is repeatedly generated during the rotation of the floodlight cover.

As the brush changes its position slightly, the surface dust removal efficiency of the floodlight cover is increased accordingly.

And by installing the rotary guide portion 400 in the form of a wing so that the light cover can be rotated simply by using wind power without the electric structure, the structure is much simpler than the conventional technology using the conventional electric motor, as well as the risk of failure There is no choice but to write.

In addition, since the present invention can clean not only the outer surface but also the inner surface of the floodlight cover through the first removal unit 520 and the second removal unit 530, the light emission efficiency is lowered due to dust accumulated on the inner surface. It also has an effect that can be prevented.

7 to 9 are views showing a modified embodiment of the present invention, the basic concept to remove the dust on the surface while rotating the light cover 200 using the rotation guide 400 is the previous embodiment Same as, but there is a difference in the form of the rotation induction unit 400 implemented by the electric method.

In this case, as shown in FIG. 7, in the state in which the driving motor 420 is installed at the fixed frame 510, the first rotation body 430 having a belt pulley type is connected to the driving shaft of the driving motor 420, and the light cover 200. The rotational tube 222 of the circumferential surface of the belt pulley-shaped second rotating body 440 is also installed, the first rotating body 430 and the second rotating body 440 can be connected to each other through a belt, etc. Made of structure.

With this structure, as the first rotating body 430 is rotated by the driving motor 420, the first rotating body 430 also rotates together, and the second cover 440 rotates the light cover 200. ) The whole is rotated about the fixed rod (210).

And as the light cover 200 is rotated in this way, the dust on the inner and outer surface is removed by the first brush and the second brush.

For reference, in the first embodiment, since it is difficult to obtain rotational force of the light cover in a room or a tunnel without natural wind, the present embodiment is suitable for use in a place where a natural wind does not occur like a room or a tunnel.

In the present embodiment, a separate automatic power control switching unit 600 is connected to the driving motor 420. The switching unit 600 functions to automatically supply and cut off power, and a switch switch has a basic switch function of current switching. It is positioned in the state overlapped with the piece 610 and the basic switch piece 610, but when heated to a predetermined temperature is composed of a deformation switch piece 620 of a material having the property of bending itself.

Therefore, when power is supplied in a state where both the basic switch piece 610 and the deformation switch piece 620 are connected to each other in a flattened state as shown in FIG. 8, power is transmitted to the driving motor to remove dust while rotating the light cover. As the temperature of the deformation switch is increased in the power supply process, the deformation switch piece 620 is deformed by itself, and eventually the basic switch piece 610 is also bent together as shown in FIG. 9 to be separated from the contact point. The power supply is cut off automatically.

Various features of the present invention described above may be implemented by various modifications and combinations by those skilled in the art, but such modifications and combinations make the floodlight cover transparent and the light cover rotates while the brush is fixed to contact with the brush. By cleaning the surface by the simplification of the structure compared to the conventional and if it is related to the configuration and the purpose of not impeding light transmission efficiency should be determined to fall within the protection scope of the present invention.

It can be installed in various lamps and street lamps so as to implement the automatic cleaning function.
