Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for generating negative ions, and particularly to a room of a general household, a hotel or the like, a room such as an office, a restaurant, a coffee shop, or any other desired place (hereinafter referred to as a room). It is configured so as to be suitable for use.

[0002] In the atmosphere, positive and negative ions are usually present at almost the same density, and if this balance is disturbed by, for example, environmental pollution, the negative ions decrease, and, for example, in a mental aspect, it is stimulating. It is known to cause unfavorable effects such as the appearance of effects, or cause unfavorable effects that impair health in physical aspects.

In view of the above, the present invention artificially replenishes a decreasing amount of negative ions in a room to obtain a calming effect in the mental aspect, or a preferable effect in the physical aspect. Is obtained.

2. Description of the Related Art Illumination devices that generate negative ions are known in the art. However, there is no device that arranges this device in a room or the like to positively exert its advantage to the human body.

[0005]

In the prior art, in particular, there is no device for positively generating negative ions in a room, and therefore, for example, the density of positive ions is lower than that of negative ions due to environmental pollution. As a result, people lived in a lot of situations, and as a result, for example, unfavorable effects on both mental and physical aspects were likely to occur.

Therefore, the present invention provides a negative ion generating illumination device for artificially replenishing negative ions in a room or the like in order to solve the above-mentioned adverse effect on the human body due to the decrease of negative ions with respect to positive ions. is there.

[0007]

SUMMARY OF THE INVENTION A negative ion generating illuminator according to the present invention is a light source having a light source provided on a support and a small metal substance which emits photoelectrons on its inner peripheral surface by projecting light rays from the light source. It comprises negative ion generating means composed of an outer cylinder for accommodating, and a cover for the outer cylinder which is provided with inflow / outflow holes for inflowing / outflowing air in the vicinity of the negative ion generating means.

[0008]

According to the present invention, when a light beam from a light source is projected onto a small metal substance attached to the inner surface of an outer cylinder, photoelectrons are emitted into the air due to a photoelectric effect, and the photoelectrons are attached to oxygen molecules to cause a negative effect. Ions are formed. In order to effectively perform the process in which the photoelectrons that form the negative ions adhere to oxygen molecules in the air, the ambient air is forced by using the upward air flow phenomenon in the outer tube cover due to the lighting of the light source. While flowing in, it is forcibly discharged from the inside of the outer cylinder cover to the outside. The above series of operations is continuously performed while the light source is on.

As a result, negative ions, which tend to decrease with respect to the density of positive ions due to environmental pollution and the like, are replenished into the air in the room, and favorable effects are obtained in both mental and physical aspects.

In FIG. 1, reference numeral 1 denotes a support base, and a socket 2 is provided at the center of the top surface of the support base 1, for example, and a known fluorescent lamp for illumination (hereinafter referred to as a light source) is provided in the socket 2.
3 terminals are connected. Reference numeral 4 denotes an outer cylinder for accommodating the light source 3, and the light source 3 is accommodated in the outer cylinder 4. The lower end opening edge portion of the outer cylinder 4 is attached to and supported by the support base 1 or the socket 2. Has been done.

A known small metal material 5 suitable for emitting photoelectrons is attached to the inner surface of the outer cylinder 4 by projecting a light beam from the light source 3. This metal material is not attached to the entire inner surface of the outer cylinder, but is attached for example in the longitudinal direction, the lateral direction, or the tilt direction at intervals so that it can be used together for illumination. Therefore, the outer cylinder 4 is formed of a material that transmits light rays.

A push button switch 10 for connecting and disconnecting a commercial power source to and from the socket 2 is provided at a position where the support base 1 is easily operated. Reference numeral 11 indicates a lead wire having a plug for connecting to a commercial power source at one end. The overall shape of the support base 1 is not limited to that shown in the figure, and can be designed and implemented in any shape.

The shape of the light source 3 is not limited to the U-shape shown in the drawing, but may be any other shape.

A mounting recess 6 centered on the center of the light source 3 is provided on the upper surface of the support base 1, and the lower end opening of an outer cylinder cover 7 for covering the outer cylinder 4 is provided in the recess 6. Is attached and supported.

An inflow hole 8 is formed on the lower side of the outer cylinder cover 7 to allow the surrounding air to flow into the outer cylinder cover 7, and the upper side is provided with the inflow air. An outflow hole 9 for returning the inside is opened.

The overall shape of the outer cylinder cover 7 is circular when viewed from the front.
It may have any shape such as a non-circular shape or a polygonal shape, and is made of any material such as a transparent material, a semi-transparent material and an opaque material.

The mounting means for the outer cylinder and the outer cylinder cover is not limited to the means shown in the figure, and other mounting means may be applied. The point is that the structure is detachable. The positions, shapes, and numbers of the inflow / outflow holes 8 and 9 are not limited to those shown in the drawings.

Since the present invention is constructed as described above, it is first arranged in a proper place in the room and its lead wire is connected to the commercial power source. Then, the push button switch is turned on to turn on the light source. By this lighting, the light beam is irradiated on the small metal substance attached to the inner surface of the outer cylinder, and here,
Due to the photoelectric effect, photoelectrons are emitted into the air and are attached to oxygen molecules to form negative ions. In the process of forming the negative ions, when the light source is turned on, an ascending air flow phenomenon occurs in the outer cylinder cover, and the surrounding air is introduced into the outer cylinder cover from the inflow hole on the lower side of the outer cylinder cover. By forcibly inflowing and releasing the photoelectrons into the inflowing air, negative ions are effectively formed and returned to the room through the outflow holes. As a result, the effect of supplementing the negative ions is sufficiently exerted.

The present invention can be constructed so that it can be used for wall hangings and hanging. Further, as one of the embodiments of the present invention, it is convenient to use the external cylinder cover in a removed state.

As described above, according to the present invention, it is possible to reduce the density of positive ions due to environmental pollution by an extremely simple operation of arranging the device in a proper place in a room and turning on a light source. It is possible to replenish some negative ions into the air in the room. As a result, a favorable state can be obtained in both mental and physical aspects. The above effect is exhibited while the light source is used for illumination. Furthermore, the present invention also exhibits a function for interior decoration.
