  Among the methods for generating ions in the air, the amount of ozone generation is small and ions can be generated at a relatively low cost. Therefore, a method often used is an electron emission type generation method. In this method, electrons are emitted by applying a pulse of a high voltage (a negative voltage of several kV) to a needle-like discharge electrode, and the emitted electrons are combined with surrounding oxygen or the like. Negative ions are generated. In this method, it is necessary to apply a high voltage to the discharge electrode. Therefore, when a lighting device having a function of generating ions using this method is commercialized, the influence of the high voltage generated in the ion generating unit on the lighting unit. Is a problem.

  In the light bulb-type lighting device described in Patent Document 1, this problem is solved by increasing the distance between the ion generation unit and the lighting unit. Therefore, although the light bulb-type lighting device described in Patent Document 1 is structured to be attached to a base socket of a normal light bulb, the light bulb occupies a considerably large volume. For this reason, it cannot be exchanged in size for a light bulb with a size restriction such as a cover at the installation location. In addition, it can be replaced if it is a light bulb installed in a place where there is no size restriction, but it is considerably larger in volume than a normal light bulb, so it will not look good if you replace it, or a tall person May hit your head.

  In the straight tube type fluorescent lamp described in Patent Document 2, this problem is not taken into consideration. For this reason, in this lighting device, there is a high possibility that the high voltage generated in the ion generating part will adversely affect the electric circuit of the fluorescent lamp. There is a risk of malfunction that will not occur.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a straight tube illumination device with an ion generation function that can prevent a high voltage generated in an ion generation unit from adversely affecting the illumination unit. And

In order to achieve the above object, a straight tube illumination device with an ion generation function according to the present invention is provided.
A first terminal protruding from the first end of the straight pipe;
A second terminal protruding from a second end different from the first end;
An ion generator that generates electricity by acquiring electricity only from the first terminal;
An illumination unit that obtains the electricity from only the second terminal and outputs light;
Is provided.

  According to the present invention, it is possible to prevent a high voltage generated in the ion generation unit from adversely affecting the illumination unit.

  Hereinafter, a straight tube illumination device with an ion generation function according to an embodiment of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

(First embodiment)
As shown in FIG. 1, a straight tube illuminating device 100 with an ion generating function according to the first embodiment of the present invention has the same shape as a normal straight tube fluorescent lamp, and has a base 10 at one end. A terminal 11 (first terminal) is provided, and a base 20 and a terminal 21 (second terminal) are provided at the other end. As shown in FIG. 1, the terminal 11 is two terminals coming out of the base 10 (first end), and the terminal 21 is two terminals coming out of the base 20 (second end). . AC 100V is input to the terminal 11 and the terminal 21, respectively.

  And the straight tube | pipe type illuminating device 100 with an ion generating function is equipped with the glass tube 30 between the nozzle | cap | die 10 and the nozzle | cap | die 20 of both ends. Note that the base 10 and the base 20 are simply called “bases” for convenience because both ends of the conventional straight tube type fluorescent lamp are called bases. This is a cylindrical case. Further, the glass tube 30 is also called a “glass tube” for convenience because the portion sandwiched between the caps at both ends in the conventional straight tube type fluorescent lamp is a glass tube, and it is not necessary to limit it to glass. For example, it may be made of plastic.

  The straight tube illumination device 100 with an ion generation function includes an ion generation unit 40 inside the base 10. The ion generation unit 40 includes an ion generation electrode 41 whose tip is in a fiber shape. The ion generation unit 40 acquires electric power (100 V AC electricity) necessary for the operation from the terminal 11, converts it into DC high voltage electricity, and applies a negative high voltage (in a pulse form to the ion generation electrode 41). −3 kV to −10 kV). Thereby, electrons are emitted from the ion generating electrode 41, and the emitted electrons are combined with oxygen in the air, thereby generating negative ions.

  As shown in FIG. 2, the tip of the ion generating electrode 41 is exposed to the outside of the base 10 through the hole 12 opened in the base 10. Since a high voltage is applied to the ion generation electrode 41, it is dangerous to directly touch a person. Therefore, as shown in FIG. 2, the protective cover 13 with the ion emission slit 14 opened covers the ion generation electrode 41. Is attached to the base 10. As a material of the protective cover 13, an insulator such as plastic or silicon is used. Although not shown, in order to ensure insulation performance, it is desirable that the thickness of the protective cover 13 is 1 mm or more.

  Returning to FIG. 1, the straight tube illumination device 100 with an ion generation function includes an illumination power supply unit 51 inside the base 20, an illumination substrate unit 52 inside the glass tube 30, and the illumination power supply unit 51 and the illumination substrate unit. 52 is connected internally. The illumination power supply unit 51 and the illumination substrate unit 52 constitute the illumination unit 50. The illumination board part 52 is a board | substrate with which LED (Light Emitting Diode: Light emitting diode) was attached. The illumination power supply unit 51 acquires 100V AC electricity from the terminal 21, converts it into DC low voltage electricity necessary for the operation of the illumination substrate unit 52, and supplies the electricity to the illumination substrate unit 52. Then, light is output from the LED attached to the illumination board part 52. Since the illumination substrate unit 52 outputs light by LEDs, it can output light with lower power consumption than a conventional fluorescent lamp, and has a longer life. In addition, the illumination board | substrate part 52 is not limited to LED, For example, the board | substrate with which EL (Electro-Luminescence) etc. was attached may be sufficient.

  As shown in FIG. 1, the size of the straight tube illumination device 100 with an ion generation function is such that the length of the base 10 and the base 20 is about 56 mm, and the length of the glass tube 30 is about 1086 mm. However, it is not limited to this size. If the straight tube illumination device 100 with the ion generation function includes the ion generation unit 40 inside the base 10 and can secure the distance between the ion generation unit 40 and the illumination unit 50 to a predetermined safety distance or more, The sizes of the caps 10 and 20 and the glass tube 30 can be arbitrarily set.

  Here, the value of the safety distance (distance to be ensured between the ion generation unit 40 and the illumination unit 50) will be considered because the air insulation performance is generally said to be 3 kV / mm. Since the upper limit of the high voltage generated in the ion generator 40 can be assumed to be −10 kV, the minimum distance for ensuring the air insulation performance is 3.33 mm. If it is sufficient to secure this 10-fold distance for safety, the safety distance is 3.33 cm. In addition, since this is an upper limit value, for example, if the high voltage generated in the ion generator 40 is assumed to be −6 kV, the safety distance is 2 cm.

  As described above, the straight tube illumination device 100 with the ion generation function is configured so that the distance between the illumination unit 50 (particularly, the illumination power supply unit 51 that is a power source of the illumination unit 50) and the ion generation unit 40 is physically above the safety. Can be separated by more than a distance. Therefore, it is possible to prevent the high voltage generated in the ion generation unit 40 from adversely affecting the illumination unit 50 (in particular, the illumination power supply unit 51 that is a power source of the illumination unit 50).

(Second Embodiment)
In the straight tube illumination device 100 with an ion generation function, the ion generation unit 40 and the illumination power supply unit 51 are physically considerably separated (1 m or more). However, since the illumination substrate unit 52 extends to the vicinity of the ion generation unit 40 inside the glass tube 30, a high voltage generated in the ion generation unit 40 may adversely affect the illumination substrate unit 52. In order to prevent this adverse effect, the length of the illumination substrate portion 52 can be simply reduced and the distance from the ion generating portion 40 can be increased within the glass tube. However, if it does so, the problem that the luminous intensity of the glass tube of the ion generation part 40 vicinity will fall will arise. Therefore, by providing an isolation part for isolating the high voltage generated in the ion generating part 40, the book prevents the high voltage from adversely affecting the illumination board part 52 without shortening the length of the illumination board part 52. A second embodiment of the invention will be described.

  As shown in FIG. 3, the straight tube type lighting device 101 with an ion generating function according to the second embodiment of the present invention is related to the first embodiment except that a separating portion 42 is provided inside the base 10. This is the same as the straight tube illumination device 100 with an ion generation function. The isolation part 42 is an insulator for reinforcing the insulation between the ion generation part 40 and the illumination part 50 (particularly the illumination board part 52) (improves the insulation performance over air). Specifically, it is a disk-like thing made of silicon and having a thickness of about 1 cm to 2 cm, and is disposed on the glass tube 30 side portion of the base 10. It is desirable that the size of the disk of the separating portion 42 is such that it fits snugly on the inner periphery of the base 10 without a gap. In addition, the isolation | separation part 42 is not limited to a silicon | silicone, What is necessary is just a material which can improve insulation performance rather than air. For example, a phenol laminate, a glass epoxy laminate, or the like may be used.

  In addition, as shown in FIG. 4, it is desirable to arrange the ion generation electrode 41 and the isolation portion 42 so that the ion generation electrode 41 is located closer to the terminal 11 than the isolation portion 42. By disposing the isolation part 42 in this way, even when the illumination substrate part 52 extends to the vicinity of the base 10, the high voltage applied to the ion generating electrode 41 is prevented from adversely affecting the illumination substrate part 52. be able to.

(Third embodiment)
In the second embodiment described above, by providing the isolation part 42, the high voltage generated in the ion generation part 40 is prevented from adversely affecting the illumination board part 52. However, this adverse effect may be prevented by simply shortening the length of the illumination substrate 52 and increasing the distance from the ion generator 40 within the glass tube 30. However, the luminous intensity in the vicinity of the ion generating part 40 of the glass tube 30 is reduced simply by shortening the length of the illumination substrate part 52. Therefore, a third embodiment of the present invention that prevents a decrease in luminous intensity by providing a light guide in this portion will be described.

  As shown in FIG. 5, the straight tube type illumination device 102 with an ion generation function according to the third embodiment of the present invention has a short illumination board part 52 inside the glass tube 30 and the illumination board part 52. Is the same as the straight tube illumination device 100 with the ion generating function according to the first embodiment, except that the light guide 53 is provided in the space generated along with the shortening. The light guide unit 53 includes a light guide plate that guides light output from the illumination substrate unit 52 to a portion where the illumination substrate unit 52 does not extend.

  The straight tube illumination device 102 with the ion generation function includes the light guide unit 53, thereby preventing a decrease in luminous intensity in the vicinity of the ion generation unit 40 of the glass tube 30. Further, by shortening the illumination substrate portion 52, it is possible to prevent a high voltage applied to the ion generating electrode 41 from adversely affecting the illumination substrate portion 52.

  In FIG. 5, the length of the light guide portion 53 is shorter than the length of the illumination substrate portion 52. However, it is not limited to this. For example, the light guide part 53 is spread from end to end inside the glass tube 30, the illumination board part 52 is arranged on the base 20 together with the illumination power supply part 51, and the light is guided from the illumination board part 52 arranged on the base 20. Light may be incident on the portion 53.

  Moreover, the straight tube | pipe type illuminating device with an ion generating function provided with both the isolation | separation part 42 and the light guide part 53 can also be comprised combining the 2nd Embodiment mentioned above and 3rd Embodiment.

  Moreover, although all the above-mentioned embodiment is a straight tube | pipe type illuminating device, it is not necessary to limit to a straight tube | pipe type. Even in a light bulb type LED lighting device including the ion generation unit 40, by providing the isolation unit 42, the high voltage generated in the ion generation unit 40 is prevented from adversely affecting the LED illumination unit without increasing the size so much. Can do. In addition, in the circular fluorescent lamp type LED lighting device including the ion generation unit 40, the provision of the isolation unit 42 and the light guide unit 53 prevents the high voltage generated in the ion generation unit 40 from adversely affecting the LED illumination unit. Can be prevented.

  Moreover, although all the above-mentioned embodiments are lighting apparatuses, it is not necessary to limit to a lighting apparatus. When the ion generator 40 is bundled in a device installed on the ceiling and supplied with power, such as a fire alarm or a smoke detector, the high voltage generated in the ion generator 40 is generated by providing the isolation unit 42. An adverse effect on the apparatus can be prevented. By installing such a device on the ceiling, it is possible to construct an environment in which negative ions always pour down from the ceiling, not only when lighting is turned on.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to the specific embodiment which concerns, This invention includes the invention described in the claim, and its equivalent range It is.
