Patent Description:
In recent years, various lighting devices having a light emitting portion that imitates the shape of flame have been developed.

As a conventional technology, for example, it is known to use a magnet in order to generate an effect of swinging flame (Patent Literature <NUM>).

In addition, Patent Literature <NUM> discloses a device with two arms provided on a flame decorative piece and a weight provided at an end thereof.

As described in Patent Literature <NUM>, it has been conventionally known that it is difficult to use an LED light as an alternative to an incandescent lamp since the LED light has strong directivity.

Patent Literature <NUM> discloses using a teardrop-shaped transparent body formed of a light transmissive material to totally reflect an LED light which has entered the teardrop-shaped transparent body and form an image, thereby creating a virtual light emitting portion.

Patent Literature <NUM> discloses a lighting device of the prior art.

As disclosed in Patent Literature <NUM>, it has been considered that it is necessary to cause an LED light to enter a transparent body since the LED light has strong directivity.

In addition, glare (dazzle) emitted from the inside of a lens when the LED light enters the transparent body has caused a problem.

Here, as a result of intensive research by the present inventors, it has been found that an LED light travels along an outer surface of a lighting equipment lens by using the lighting equipment lens having a protruding portion capable of point support and emitting a refracted LED light from a lower portion toward the protruding portion.

Furthermore, it has been found that as the LED light travels along the outer surface of the lighting equipment lens, the entire lighting equipment lens emits light, and a virtual light emitting portion can be created.

That is, an object of the present invention is to provide a novel lighting device including a virtual light emitting portion and a lighting equipment lens that swings like a balancing toy.

In addition, in a preferred mode of the present invention, an object is to provide a lighting device that alleviates glare (dazzle) from the inside of a lighting equipment lens and causes less irritation even when the lighting equipment lens is viewed directly nearby.

Furthermore, in a preferred mode of the present invention, an object is to provide a lighting device that exhibits a soft lighting manner.

The present invention that solves the problems described above is a lighting device according to claim <NUM>. The lighting device includes.

According to the present invention, it is possible to provide a novel lighting device in which the lighting equipment lens itself serves as a virtual light emitting portion and the lighting equipment lens itself swings like a balancing toy (see <FIG>).

Specifically, since the surface of the light transmitting placement portion on which the protruding portion is placed is formed into a concave shape, a light beam which has struck a slope of the light transmitting placement portion is refracted, and thus, an LED light hardly enters the lighting equipment lens.

In addition, since the lighting equipment lens includes the protruding portion, the LED light hardly enters the lighting equipment lens.

That is, with the mode described above, the LED light from the light transmitting placement portion travels along the protruding portion and along an outer surface of the lighting equipment lens. Then, as the LED light travels along the outer surface of the lighting equipment lens, the entire lighting equipment lens serves as the virtual light emitting portion.

In addition, the configuration in which the LED light hardly enters the lighting equipment lens can alleviate glare (dazzle) from the inside of the lighting equipment lens.

Since the LED light hardly enters the lighting equipment lens in such a configuration, it is possible to provide a lighting device that causes less irritation even when the lighting equipment lens is viewed directly nearby.

Furthermore, according to the present invention, it is possible to provide a lighting device that exhibits a soft lighting manner.

In a preferred mode of the present invention, the surface of the light transmitting placement portion on which the protruding portion is placed is formed into a conically recessed shape, and
an inclination angle of the surface is <NUM>° or more and <NUM>° or less.

Since the surface of the light transmitting placement portion on which the protruding portion is placed is formed into a conically recessed shape (a mortar shape), the protruding portion of the lighting equipment lens can be placed at a desired position (the central portion of the light transmitting placement portion). Furthermore, the position of a fulcrum (a placement position of the protruding portion) hardly shifts even when a lighting equipment lens <NUM> moves.

Additionally, since the surface on which the protruding portion is placed is formed into a conically recessed shape (a mortar shape), a light beam which has struck the slope of the light transmitting placement portion is refracted, and thus, the LED light hardly enters the lighting equipment lens. The configuration in which the LED light hardly enters the lighting equipment lens can alleviate glare (dazzle) from the inside of the lighting equipment lens.

In a preferred mode of the present invention, the stand member includes LED light irradiation means that is placed in the housing and allows irradiation of light toward the opening through the light transmitting placement portion.

the stand member includes:.

By forming the shape of the arm portion connecting the lighting equipment lens and the weight portion into a ring shape and curving the connecting portion, the lighting equipment lens unit swinging like a balancing toy is less likely to interfere with the connecting portion.

In a preferred mode of the present invention, the weight portion is located substantially coaxially with the protruding portion and below the protruding portion,.

With the mode described above, the magnetic force generation mechanism included in the weight portion is affected by the magnetic force generation mechanism included in the base portion.

Then, since the weight portion receives magnetic force, the lighting equipment lens unit swings like a balancing toy more reliably for a longer time.

More specifically, the movement of the lighting equipment lens unit that starts to swing like a balancing toy due to ambient wind or the like can be assisted by the magnetic force generation mechanism. Then, with the movement assistance by the magnetic force, it is possible to provide a lighting device that exhibits natural fluctuation with less regularity, which is closer to real flames of candles and the like.

In a preferred mode of the present invention, a waterproof mechanism is provided so that the inside of the housing and the light transmitting placement portion are liquid-tight.

Specifically, since the surface of the light transmitting placement portion <NUM> on which the protruding portion <NUM> is placed is formed into a concave shape, a light beam which has struck a slope of the light transmitting placement portion <NUM> is refracted, and thus, the LED light hardly enters the lighting equipment lens <NUM>.

In addition, since the lighting equipment lens <NUM> includes the protruding portion <NUM>, the LED light hardly enters the lighting equipment lens <NUM>.

That is, with the mode described above, the LED light from the light transmitting placement portion <NUM> travels along the protruding portion <NUM> and along an outer surface of the lighting equipment lens <NUM>. Then, as the LED light travels along the outer surface of the lighting equipment lens <NUM>, the entire lighting equipment lens <NUM> serves as a virtual light emitting portion.

In addition, the configuration in which the LED light hardly enters the lighting equipment lens <NUM> can alleviate glare (dazzle) from the inside of the lighting equipment lens.

Furthermore, according to the present invention, it is possible to provide the lighting device <NUM> that exhibits a soft lighting manner.

Since the lighting equipment lens unit <NUM> swings like a balancing toy, it is possible to make the appearance of the light emission from the lighting equipment lens <NUM> more similar to fire.

In addition, since the lighting equipment lens <NUM> itself swings, the LED light itself that travels along the lighting equipment lens <NUM> also swings exquisitely, thereby making the appearance of the light emission from the lighting equipment lens <NUM> more similar to fire (see <FIG> and <FIG>).

Hereinafter, a more preferred mode of the lighting device <NUM> of the lighting device <NUM> of the present embodiment will be described in detail with reference to <FIG>.

In the present specification, the lighting equipment lens unit <NUM> refers to a unit member consisting of a combination of the lighting equipment lens <NUM> and components which allow the lighting equipment lens <NUM> to be placed (see <FIG>).

As illustrated in <FIG> and <FIG>, the lighting equipment lens unit <NUM> includes a lighting equipment lens <NUM>, a weight portion <NUM>, and an arm portion <NUM> connecting the lighting equipment lens <NUM> and the weight portion <NUM>.

Hereinafter, each configuration of the lighting equipment lens unit <NUM> in the lighting device <NUM> of the present embodiment will be described in detail.

In the present specification, "lighting equipment lens <NUM>" refers to a lens used in lighting equipment for the purpose of creating a virtual light emitting portion at a position away from an actual light source (see <FIG>).

The lighting equipment lens <NUM> of the present embodiment is made of a material having translucency.

Here, "having translucency" in the present specification means a property capable of transmitting light. In addition, "material having translucency" in the present specification encompasses both a translucent material and a transparent material.

Here, the lighting equipment lens <NUM> is preferably a transparent body.

Since the lighting equipment lens <NUM> is a transparent body, it is possible to receive light from the sun or another light source. Then, by combining the LED light from the light transmitting placement portion <NUM> and sunlight or light from another light source, it is possible to form a light emitting portion unique to an environment in which the lighting device <NUM> of the present invention is placed.

The material for the lighting equipment lens <NUM> of the present embodiment is an acrylic resin (see <FIG>).

Here, in the present invention, the material for the lighting equipment lens <NUM> is not particularly limited.

As the material for the lighting equipment lens <NUM>, for example, a synthetic resin (organic glass) or glass can be preferably used in addition to the material described above.

In addition, an overall shape of the lighting equipment lens <NUM> of the present embodiment is a tapered shape (corresponding to the protruding portion <NUM> in the present invention) at the lower end in the major axis direction of a prolate spheroid and a tapered shape at the upper end in the major axis direction of the prolate spheroid when the lighting equipment lens <NUM> is placed such that the major axis direction of the prolate spheroid is oriented at the top and bottom (see <FIG>).

Here, the protruding portion <NUM> of the present embodiment is formed into a pointed shape whose diameter gradually decreases downward.

Since the protruding portion <NUM> is formed into a pointed shape whose diameter gradually decreases downward, it is possible to balance the lighting equipment lens unit <NUM> more efficiently.

In addition, the protruding portion <NUM> of the present embodiment is formed such that light from the LED light irradiation means <NUM> enters the protruding portion <NUM> at an acuter angle than the total reflection angle.

With the mode described above, it is possible to alleviate glare (dazzle) from the inside of the lighting equipment lens.

Here, regarding the degree of acuteness of the protruding portion <NUM>, the angle of the central angle is preferably <NUM>° or more, more preferably <NUM>° or more, more preferably <NUM>° or more, more preferably <NUM>° or more, and still more preferably <NUM>° or more when the protruding portion <NUM> is seen in a developed view.

In addition, regarding the degree of acuteness of the protruding portion <NUM>, the angle of the central angle can be preferably <NUM>° or less, more preferably <NUM>° or less, and more preferably <NUM>° or less as a target when the protruding portion <NUM> is seen in the developed view.

Here, for the central angle of the protruding portion <NUM>, it is possible to use a value obtained by approximating the developed view of the protruding portion <NUM> to a developed view of a cone.

In addition, the upper end side of the lighting equipment lens <NUM> of the present embodiment is formed into an obtuse shape whose diameter gradually decreases upward in comparison with the protruding portion <NUM>.

Here, regarding the degree of obtuseness of the upper end side of the lighting equipment lens <NUM>, the angle of the central angle is preferably <NUM>° or more, more preferably <NUM>° or more, more preferably <NUM>° or more, and more preferably <NUM>° or more when the upper end portion of the lighting equipment lens <NUM> is seen in a developed view.

In addition, regarding the degree of obtuseness of the upper end side of the lighting equipment lens <NUM>, the angle of the central angle can be preferably <NUM>° or less, more preferably <NUM>° or less, and more preferably <NUM>° or less as a target when the upper end side of the lighting equipment lens <NUM> is seen in the developed view.

Here, for the central angle of the upper end side of the lighting equipment lens <NUM>, it is possible to use a value obtained by approximating the developed view of the upper end side of the lighting equipment lens <NUM> to a developed view of a cone.

Since the lighting equipment lens <NUM> includes the protruding portion <NUM>, it is possible to point-support the entire lighting equipment lens unit <NUM> by the lighting equipment lens <NUM>.

Since the entire lighting equipment lens unit <NUM> can be point-supported by the lighting equipment lens <NUM>, the LED light from the light transmitting placement portion <NUM> travels along the protruding portion <NUM> and along the outer surface of the lighting equipment lens <NUM>. Then, as the LED light travels along the outer surface of the lighting equipment lens <NUM>, the entire lighting equipment lens <NUM> serves as a virtual light emitting portion.

However, in the present invention, the shape of the protruding portion <NUM> may be a conical shape whose diameter gradually decreases downward.

Since the protruding portion <NUM> has a shape whose diameter gradually decreases downward, the LED light travels along the outer surface of the lighting equipment lens <NUM> more reliably. Then, as the LED light travels along the outer surface of the lighting equipment lens <NUM>, the entire lighting equipment lens <NUM> serves as a virtual light emitting portion.

In the present invention, the entire lighting equipment lens unit <NUM> can be point-supported by the protruding portion <NUM> of the lighting equipment lens <NUM>.

In addition, the lighting equipment lens <NUM> includes the protruding portion <NUM> and has a shape which allows an LED light refracted by the light transmitting placement portion <NUM> described later to travel along the outer surface.

In non-claimed embodiments, the overall shape of the lighting equipment lens <NUM> may be, for example, a conical shape, a pyramidal shape, or a shape in which the lower end in the major axis direction of a spherical shape is tapered.

Here, in the present invention, the overall shape of the lighting equipment lens <NUM> is preferably a rotationally symmetrical shape about the substantially central axis of the protruding portion <NUM>.

In addition, the entire size of the lighting equipment lens <NUM> is not particularly limited as long as the lighting equipment lens <NUM> can be placed on the light transmitting placement portion <NUM> described later and the effect of the present invention is not impaired.

In the present specification, the weight portion <NUM> is a member that adjusts the center of gravity of the lighting equipment lens unit <NUM> such that it is located substantially coaxially with the protruding portion <NUM> and below the protruding portion <NUM>.

The weight portion <NUM> allows the center of gravity of the lighting equipment lens unit <NUM> to be located substantially coaxially with the protruding portion <NUM> and below the protruding portion <NUM>.

Since the center of gravity of the lighting equipment lens unit <NUM> is located substantially coaxially with the protruding portion <NUM> and below the protruding portion <NUM>, the lighting equipment lens <NUM> itself swings like a balancing toy with the protruding portion <NUM> as a fulcrum.

Then, since the lighting equipment lens unit <NUM> swings like a balancing toy, it is possible to make the appearance of the light emission from the lighting equipment lens <NUM> more similar to fire.

In addition, since the lighting equipment lens <NUM> itself swings, the LED light itself that travels along the lighting equipment lens <NUM> also swings exquisitely, thereby making the appearance of the light emission from the lighting equipment lens <NUM> more similar to fire.

The weight portion <NUM> of the present embodiment is located substantially coaxially with the protruding portion <NUM> and below the protruding portion <NUM>.

The weight portion <NUM> is provided with a weight magnetic force generation mechanism <NUM>.

With the mode described above, the weight magnetic force generation mechanism <NUM> included in the weight portion <NUM> is affected by a base magnetic force generation mechanism <NUM> included in a base portion <NUM>.

Then, since the weight portion <NUM> receives magnetic force, the lighting equipment lens unit <NUM> swings like a balancing toy more reliably for a longer time.

More specifically, the movement of the lighting equipment lens unit <NUM> that starts to swing like a balancing toy due to ambient wind or the like can be assisted by the magnetic force generation mechanism (the weight magnetic force generation mechanism <NUM> and the base magnetic force generation mechanism <NUM>). Then, with the movement assistance by the magnetic force, it is possible to provide a lighting device that exhibits natural fluctuation with less regularity, which is closer to real flames of candles and the like.

The weight magnetic force generation mechanism <NUM> of the present embodiment is a neodymium magnet. By using the neodymium magnet, it is possible to design the overall shape of the weight portion <NUM> compactly.

Then, by making the overall shape of the weight portion <NUM> compact, the lighting equipment lens unit <NUM> is less likely to interfere with another component when the lighting equipment lens unit <NUM> swings like a balancing toy.

However, in the present invention, the weight magnetic force generation mechanism <NUM> may be any of a ferrite magnet, a neodymium magnet, a samarium-cobalt magnet, an alnico magnet, and an electromagnet.

In the present invention, the number, weight, and mechanism of the weight portion <NUM> are not particularly limited.

In the present specification, the arm portion <NUM> is a member connecting the lighting equipment lens <NUM> and the weight portion <NUM> described above.

Here, in the present embodiment, the two arm portions <NUM> are provided so as to hang downward from the lighting equipment lens <NUM>.

Furthermore, the arm portions <NUM> of the present embodiment are placed such that the overall shape of the arm portions <NUM> is symmetrical with the axis of the protruding portion <NUM> as a median line (see <FIG>).

In addition, the overall shape of the arm portions <NUM> of the present embodiment is preferably line-symmetric with the axis of the protruding portion <NUM> as a median line.

With the mode described above, it is possible to provide the lighting device <NUM> with more sense of unity.

Here, the overall shape of the arm portions <NUM> is preferably a ring shape when viewed from the front.

By forming the overall shape of the arm portions <NUM> connecting the lighting equipment lens <NUM> and the weight portion <NUM> into a ring shape, the lighting equipment lens unit <NUM> swinging like a balancing toy is less likely to interfere with another component.

By forming the overall shape of the arm portions <NUM> into a ring shape, it is possible to provide the lighting equipment lens unit <NUM> with an aesthetically better appearance.

Furthermore, since the overall shape of the arm portions <NUM> is a line-symmetric ring shape with the axis of the protruding portion <NUM> as a median line, it is possible to place the weight portion <NUM> substantially coaxially with the protruding portion <NUM> and below the protruding portion <NUM>.

However, in the present invention, the shape of the arm portion <NUM> does not necessarily have to be symmetrical as long as it is possible to balance the entire lighting equipment lens unit <NUM> with the protruding portion <NUM> as a fulcrum.

In the present invention, the shape, size, and material of the arm portion <NUM> are not particularly limited.

In the lighting device <NUM> of the present embodiment, the arm portion <NUM> and the weight portion <NUM> are configured as separate members.

However, in the present invention, the arm portion <NUM> and the weight portion <NUM> may be integrally formed.

Furthermore, the weight portion <NUM> may also serve as the arm portion <NUM>.

In addition, the material, size, shape, and the like of the arm portion are not particularly limited.

In addition, a wall surface of the housing <NUM> of the present embodiment also serves as a shade portion <NUM> that shades unnecessary light out of the LED light emitted through the light transmitting placement portion <NUM>.

With the mode including the shade portion <NUM>, even when a user approaches the lighting device <NUM> and checks a light source portion, a light source of the LED light irradiation means <NUM> does not enter user's eyes.

Here, the <NUM>/<NUM> beam angle of the light from the LED light irradiation means <NUM>, defined by the shade portion <NUM>, is <NUM>°.

The <NUM>/<NUM> beam angle of the light from the LED light irradiation means <NUM> refers to a value obtained by doubling an angle (α in <FIG>) from a central portion (the central axis) at which the luminous intensity of the light is the maximum to a position at which the luminous intensity is <NUM>/<NUM> of the brightness at the central portion (the central axis).

The <NUM>/<NUM> beam angle of the light from the LED light irradiation means <NUM>, defined by the shade portion <NUM>, may be preferably <NUM>° or more, more preferably <NUM>° or more, and still more preferably <NUM>° or more.

When the <NUM>/<NUM> beam angle of the light from the LED light irradiation means <NUM>, defined by the shade portion <NUM>, is equal to or larger than the lower limit, it is possible to brighten the entire lighting equipment lens <NUM> efficiently.

The <NUM>/<NUM> beam angle of the light from the LED light irradiation means <NUM>, defined by the shade portion <NUM>, is preferably <NUM>° or less, more preferably <NUM>° or less, and still more preferably <NUM>° or less.

When the <NUM>/<NUM> beam angle of the light from the LED light irradiation means <NUM>, defined by the shade portion <NUM>, is equal to or less than the upper limit, it is possible to brighten the entire lighting equipment lens <NUM> efficiently.

With the mode described above, even when a user approaches the lighting device <NUM> and checks the light source portion, the light source of the LED light irradiation means <NUM> does not enter user's eyes.

Here, the housing <NUM> of the present embodiment has a cylindrical shape.

Furthermore, since the housing <NUM> has a cylindrical shape, even when a user approaches the lighting device <NUM> and checks the light source portion, the light source of the LED light irradiation means <NUM> does not enter user's eyes.

The opening <NUM> of the housing <NUM> has a circular shape when viewed in plan view.

With the mode described above, it is possible to brighten the entire lighting equipment lens <NUM> more reliably and efficiently.

In addition, the opening <NUM> of the housing <NUM> when viewed in plan view is smaller than the area of the lighting equipment lens <NUM> described above in plan view (see <FIG> and <FIG>).

In addition, with the mode described above, even when a user approaches the lighting device <NUM> and checks the light source portion, the light source of the LED light irradiation means <NUM> does not enter user's eyes.

However, in the present invention, the shape and size of the housing <NUM> are not particularly limited as long as the light transmitting placement portion <NUM> and the LED light irradiation means <NUM> described later can be placed.

Here, the light transmitting placement portion <NUM> of the present embodiment is a member that is placed inside the housing <NUM> and allows placement of the protruding portion <NUM>.

The light transmitting placement portion <NUM> of the present embodiment is made of a material having translucency.

The light transmitting placement portion <NUM> of the present embodiment also serves as a lens member.

Here, the light transmitting placement portion <NUM> is preferably a transparent body.

Since the light transmitting placement portion <NUM> is a transparent body, it is possible to provide the lighting device <NUM> with an aesthetically better appearance.

In the lighting device <NUM> of the present embodiment, the surface of the light transmitting placement portion <NUM> on which the protruding portion <NUM> is placed is formed into a conically recessed shape (a mortar shape).

Since the surface of the light transmitting placement portion <NUM> on which the protruding portion <NUM> is placed is formed into a conically recessed shape (a mortar shape), the protruding portion <NUM> of the lighting equipment lens <NUM> can be placed at a desired position (the central portion of the light transmitting placement portion <NUM>). Then, after the protruding portion <NUM> of the lighting equipment lens <NUM> is placed at the central portion of the light transmitting placement portion <NUM>, the position of a fulcrum (a placement position of the protruding portion <NUM>) hardly shifts even when the lighting equipment lens <NUM> moves.

Since the surface on which the protruding portion <NUM> is placed is formed into a conically recessed shape (a mortar shape), a light beam which has struck a slope of the light transmitting placement portion <NUM> is refracted, and thus, the LED light hardly enters the lighting equipment lens <NUM>. Then, the configuration in which the LED light hardly enters the lighting equipment lens <NUM> can alleviate glare (dazzle) from the inside of the lighting equipment lens.

Since the LED light hardly enters the lighting equipment lens in such a configuration, it is possible to provide a lighting device with less irritation even when the lighting equipment lens is viewed directly nearby.

When the inclination angle of the surface of the light transmitting placement portion <NUM>, formed into a conically recessed shape (a mortar shape), is equal to or larger than the upper limit, it is possible to brighten the entire lighting equipment lens <NUM> efficiently.

In addition, with the mode described above, the lighting equipment lens <NUM> itself serves as a virtual light emitting portion (see <FIG>).

Specifically, the LED light from the light transmitting placement portion <NUM> travels along the protruding portion <NUM> and along the outer surface of the lighting equipment lens <NUM>. Then, as the LED light travels along the outer surface of the lighting equipment lens <NUM>, the entire lighting equipment lens <NUM> serves as a virtual light emitting portion (see <FIG>).

Here, in the present invention, the surface of the light transmitting placement portion <NUM> on which the protruding portion <NUM> is placed may be formed into a concave shape.

In the present invention, the surface of the light transmitting placement portion <NUM> on which the protruding portion <NUM> is placed is preferably formed of a rotationally symmetrical surface about the substantially central axis of the light transmitting placement portion <NUM>.

The light transmitting placement portion <NUM> preferably has a thickness in the axial direction.

With the mode described above, even when a user approaches the lighting device <NUM> and checks the light source portion, the light source of the LED light irradiation means <NUM> hardly enters user's eyes.

In the lighting device <NUM> of the present embodiment, in the mode in which the light transmitting placement portion <NUM> is placed inside the housing, waterproof gasket <NUM> for a housing is provided so that the inside of the housing and the light transmitting placement portion <NUM> are liquid-tight.

With the mode described above, it is possible to provide the lighting device <NUM> that can be used even during rainfall, in which a candle cannot be used.

Here, examples of the waterproof gasket <NUM> for a housing preferably includes rubber waterproof gasket.

However, in the present invention, the type of a waterproof mechanism is not particularly limited as long as the inside of the housing and the light transmitting placement portion <NUM> can be liquid-tight.

In the lighting device <NUM> of the present embodiment, since the LED light irradiation means <NUM> is provided inside the housing <NUM>, light can be emitted from a placement surface of the lighting equipment lens unit <NUM>.

In the lighting device <NUM> of the present embodiment, the LED light irradiation means <NUM> is a light emitting diode (LED) (<FIG>).

Since the LED light irradiation means <NUM> is a light emitting diode (LED), it is possible to further suppress heat generation of the entire lighting device <NUM>.

In addition, the LED light irradiation means <NUM> does not necessarily have to consist of a single light source, and may be a light source consisting of an aggregate of two or more light sources. Examples of the light source consisting of an aggregate of two or more light sources include a light source consisting of an aggregate of R (red) G (green) B (blue) light emitting diodes.

In addition, in the lighting device <NUM> of the present embodiment, the LED light irradiation means <NUM> is provided inside the housing <NUM> so as to be positioned below the light transmitting placement portion <NUM>.

Since the LED light irradiation means <NUM> is provided inside the housing <NUM> so as to be positioned below the light transmitting placement portion <NUM>, the LED light hardly enters the lighting equipment lens <NUM>. Therefore, with the mode described above, it is possible to alleviate glare (dazzle) from the inside of the lighting equipment lens <NUM>.

However, in the present invention, the placement of the LED light irradiation means <NUM> is not particularly limited as long as the irradiation of the light toward the opening <NUM> through the light transmitting placement portion <NUM> is allowed.

In the present invention, it is only necessary that the stand member <NUM> allows the irradiation of the light toward the opening <NUM> through the light transmitting placement portion <NUM>.

In the lighting device <NUM> of the present embodiment, in the mode of being placed inside the housing, a waterproof screw <NUM> for a housing is provided so that the inside of the housing and the LED light irradiation means <NUM> are liquid-tight.

Here, examples of the waterproof screw <NUM> for a housing preferably include a rubber coated screw body.

However, in the present invention, the type of the waterproof mechanism is not particularly limited as long as the inside of the housing and the LED light irradiation means <NUM> can be liquid-tight.

Hereinafter, other components in the lighting device <NUM> of the present embodiment will be described.

The lighting device <NUM> of the lighting device <NUM> of the present embodiment includes a connecting portion <NUM> connecting the base portion <NUM> and the housing <NUM> including the light transmitting placement portion <NUM>.

Here, in the present invention, it is sufficient as long as the stand member <NUM> includes the light transmitting placement portion <NUM> for placing the protruding portion <NUM> of the lighting equipment lens unit <NUM> described above, and for example, the stand member <NUM> may have any mode of a stand member <NUM> (a hanging type lighting device <NUM>) including a hanging implement, a stand member <NUM> (a clip type lighting device <NUM>) including a clip portion for gripping a bar, and a stand member <NUM> (a handheld lighting device <NUM>) including a handle portion to be gripped by a hand.

Hereinafter, particularly preferred modes of respective components when the lighting device <NUM> is a stationary lighting device will be described.

In the present specification, the base portion <NUM> refers to a member that allows the stand member <NUM> to stand on its own when placed on the ground.

The base portion <NUM> includes the base magnetic force generation mechanism <NUM> substantially coaxial with the protruding portion <NUM>.

With the mode described above, the base magnetic force generation mechanism <NUM> included in the base portion <NUM> can affect the weight magnetic force generation mechanism <NUM> included in the weight portion <NUM>.

Since the weight portion <NUM> receives the magnetic force, the lighting equipment lens unit <NUM> swings like a balancing toy more reliably for a longer time.

In the lighting device <NUM> of the present embodiment, the base magnetic force generation mechanism <NUM> provided in the base portion <NUM> is an electromagnet. By using the electromagnet, it is possible to provide the lighting device <NUM> with the lighting equipment lens unit <NUM> swinging like a balancing toy due to power from the outside (see an electric connection terminal <NUM>).

In addition, by using the electromagnet as the base magnetic force generation mechanism <NUM>, the degree of swinging of the lighting equipment lens <NUM> can be adjusted.

However, in the present invention, the base magnetic force generation mechanism <NUM> may be any of a ferrite magnet, a neodymium magnet, a samarium-cobalt magnet, an alnico magnet, and an electromagnet.

In the present invention, the number, weight, and mechanism of the base magnetic force generation mechanism <NUM> are not particularly limited.

For example, the base portion <NUM> may include the two or more base magnetic force generation mechanisms <NUM>.

Here, in the lighting device <NUM> of the present embodiment, in the mode in which the base magnetic force generation mechanism <NUM> is placed inside the base portion <NUM>, waterproof gasket <NUM> for a base and a waterproof sheet <NUM> for a base are provided in order to prevent water from entering the base magnetic force generation mechanism <NUM>.

Here, examples of the waterproof gasket <NUM> for a base preferably includes rubber waterproof gasket.

Furthermore, examples of the waterproof sheet <NUM> for a base preferably includes a rubber waterproof sheet.

However, in the present invention, the type of the waterproof mechanism is not particularly limited as long as water does not enter the base magnetic force generation mechanism <NUM>.

The connecting portion <NUM> is a member connecting the housing <NUM> including the light transmitting placement portion <NUM>.

Here, the connecting portion <NUM> of the present embodiment includes a U-shaped curved portion <NUM> so that the connecting portion <NUM> is not positioned coaxially with the protruding portion <NUM> and horizontally in the vicinity of the weight portion <NUM>.

Since the connecting portion <NUM> is curved so that the connecting portion <NUM> is not positioned coaxially with the protruding portion <NUM> and horizontally in the vicinity of the weight portion <NUM>, the weight portion <NUM> and the connecting portion <NUM> are less likely to interfere with each other.

In addition, the connecting portion <NUM> of the present embodiment includes a bar portion <NUM> for supporting the housing <NUM> coaxially with the protruding portion <NUM>.

Since the bar portion <NUM> for supporting the housing <NUM> is provided coaxially with the protruding portion <NUM>, the arm portion <NUM> and the connecting portion <NUM> are less likely to interfere with each other.

With the mode described above, the lighting equipment lens unit <NUM> swinging like a balancing toy and the connecting portion <NUM> are less likely to interfere with each other.

However, in the present invention, the shape of the connecting portion <NUM> is not particularly limited as long as the connecting portion <NUM> connects the housing <NUM> and the base portion <NUM> and is configured not to interfere with a motion range of the lighting equipment lens unit <NUM>.

The connecting portion <NUM> of the present embodiment is formed of a hollow member.

With the mode described above, it is possible to transmit power to the LED light irradiation means <NUM> provided in the housing <NUM> through an electric line (not illustrated) (see the electric connection terminal <NUM>).

In addition, since the connecting portion is formed of a hollow member, it is possible to reduce the weight of the entire lighting device <NUM>.

In the lighting device <NUM> of the present embodiment, the connecting portion <NUM> and the housing <NUM> are integrally formed.

However, in the present invention, the connecting portion <NUM> and the housing <NUM> may be configured as separate members.

Furthermore, in the lighting device <NUM> of the present embodiment, the waterproof gasket <NUM> for a base is provided so that a connected portion between the connecting portion <NUM> and the base portion <NUM> is liquid-tight.
