By the way, when incorporating an ion generator in the lighting fixture using LED, the following problems can be considered.
i) Lighting fixtures using LEDs are still expensive. The built-in ion generator is more expensive. When there is a trouble such as disconnection of an LED or the like, or failure of an ion generator to release negative ions, it may be necessary to replace the entire expensive lighting device with built-in ion generator.

In order to avoid this risk, it is preferable that the ion generator has a separate configuration. This is because it is sufficient to replace only one of them, and it is economical.
ii) Since the luminous efficiency of the LEDs has been improved due to technical progress, even if the number of LEDs is reduced, the brightness comparable to that of the conventional one can be secured.
Therefore, if the tube length is the same as the conventional tube and the same brightness, the tube length can be shorter than the conventional tube length and the material cost can be saved, so that an inexpensive lighting apparatus can be provided.

iii) In order to incorporate the ion generator itself in the tube of the lighting fixture, it is necessary to reduce the size of the drive circuit for generating ions, and thus a design with a margin cannot be made.

  Therefore, the present invention solves such a conventional problem, and proposes a base adapter capable of generating negative ions without being incorporated in a tube of a lighting fixture and a lighting fixture using the same. .

  In order to solve the above-described problems, a base adapter according to the present invention includes a cylindrical adapter body, a base mounting portion provided at one end thereof, a socket mounting electrode pin provided at the other end, and an adapter main body. And an ion generator having a discharge needle attached thereto. The discharge needle is attached so as to face outward from the through hole formed in the peripheral wall of the adapter body.

  A lighting fixture according to the present invention includes a lighting fixture body having a pair of bases with electrode pins, and a base adapter that is detachably attached to one base. The base adapter has a base mounting portion on one end side. The other end is provided with a pair of electrode pins for insertion into a socket and an ion generator having a discharge needle for discharging negative ions to the outside.

  The base adapter according to the present invention is used in a state of being mounted on the lighting fixture body. The luminaire main body with the base adapter is mounted on the socket of the frame to become the luminaire according to the present invention.

 When diverting a frame for a lighting fixture installed on the ceiling or the like, since the width of the pair of sockets is determined, the tube length of the lighting fixture body is designed to be short by the length of the base adapter. The base adapter has an ion generation function and also functions for tube length correction.

  Even if the tube length of the LED lighting fixture body is made shorter than before, the light emission efficiency of the LED itself is improved, so if the brightness is the same as the previous brightness, the number of LEDs is reduced and the tube length is shortened. Even so, the brightness is as good as before and it is economical.

 Since the discharge needle provided in the ion generator is opened to the outside from the peripheral wall of the base adapter body, the illuminator is turned on and at the same time, the ion generator is also supplied with power and negative ions are generated from the discharge needle. . Since the discharge needle faces the room, sterilization, sterilization, and the like are performed by the negative ions released into the room, so that the room environment is improved.

  If the ion generator is built in the adapter body rather than being built in the tube, the space for the ion generator can be more or less space, and the design of the drive circuit (boost section) and the attachment of the discharge needle becomes easier. Since the tube length is shortened, the lighting fixture body can be provided at low cost.

  If there is a problem that the LED etc. is broken or the ion generator fails and negative ions are not released in a lighting fixture with a built-in ion generator, replace the entire expensive lighting fixture with a built-in ion generator. However, according to the present invention, it is economical because only one of them needs to be replaced.

It is a conceptual diagram which shows an example of the base adapter which concerns on this invention, and the lighting fixture using this base adapter. It is a front view of a nozzle adapter. It is the side view. It is sectional drawing which showed the use condition of the nozzle | cap | die adapter easily. It is a figure which shows a nozzle | cap | die mounting part. It is sectional drawing which shows a nozzle | cap | die installation state to a nozzle | cap | die mounting part. It is sectional drawing which shows the attachment state of a discharge needle.

  Subsequently, an example of a cap adapter according to the present invention and a lighting fixture using the same will be described.

  FIG. 1 shows an example of a lighting fixture 10 according to the invention. In this example, a frame used in a conventional straight tube fluorescent lamp is used as it is, and the lighting fixture 10 includes a frame 10A and a lighting fixture main body (appliance main body) 10B. A pair of sockets 2 is attached to a frame 10A installed on the ceiling or the like.

  The instrument main body 10 </ b> B includes a tube body 11 and caps 13 and 13 provided on both sides of the tube body 11. On the other hand, in this example, the base adapter 20 described later is attached to the base 13 on the left side, and the base adapter 20 is attached to the sockets 2 and 2 in a state where the base adapter 20 is attached to the tube body 11.

  Here, when the conventional frame 10A is used, the length between the pair of sockets 2 and 2 is the same as the tube length of the fluorescent lamp that has been used. Therefore, the length of the instrument main body 10B is also designed accordingly, and the length of the tube body 11 and the length Lb of the base adapter 20 is designed to be the length L between the sockets 2 and 2. Yes.

 The tubular body 11 is a half tubular hollow body having a predetermined inner diameter, and has a circuit board 17 extending in the longitudinal direction therein. The tube body 11 is made of resin, and in this example, a plurality of LEDs (light emitting diodes) 18 as a plurality of light emitters are mounted on the circuit board 17 that is installed at predetermined intervals.

  Although the length La of the tube body 11 is shorter than that of a normal LED fluorescent lamp by the amount of the base adapter 20, the same brightness can be realized even with a small number due to recent technological advances. Therefore, even if the length La of the tubular body 11 is short, brightness comparable to the conventional one can be obtained.

  As in the case of the LED fluorescent lamp, bases 13 and 13 are respectively provided at the left and right ends of the tube body 11, and a part of the bases 13 and 13 functions as mounting body parts 14 and 14. Electrode pins 15 and 15 to be mounted on the sockets 2 and 2 described above are provided on the outside of the pins 14 and 14 so as to protrude. Although two electrode pins 15 and 15 are provided, either or both of them are used as electrodes depending on the lighting type of the lighting fixture 10.

  The base adapter 20 will be described with reference to FIG. 1 and FIG. The base adapter 20 has a cylindrical adapter body 21 having a predetermined length Lb. One end thereof, in this example, a base mounting part 40 is provided on the right end side, and a base part 23 is provided on the left end side. An ion generator 30 to be described later is built in the inside (the body).

  Each configuration will be described below. The base mounting portion 40 is for mounting on the left base 13 provided in the tube body 11, and an engagement piece (locking piece) 50 having a predetermined width and length from a part of the periphery of the base mounting portion 40. Is integrally formed with the base mounting part 40. The length of the engagement piece 50 is substantially equal to the length of the base 13 (excluding the mounting barrel 14). When the mounting barrel 14 is completely mounted on the base mounting portion 40 as shown in FIG. Each dimensional relationship is selected so that the engagement protrusion 51 provided in the front-end | tip part of the engagement piece 50 engages with the step part formed between the main body of the nozzle | cap | die 13, and the pipe body 11. As shown in FIG.

  By the interaction between the base mounting portion 40 and the engagement piece 50, the base adapter 20 can be reliably fixed to the tube body 11 as will be described later. In FIG. 2, a cap 55 is a protective cap for covering the electrode pins 24 and 24.

  As shown in FIG. 3, the engaging protrusion 51 is provided with a protrusion 52 on the inside thereof, which is provided so that the base adapter 20 can be easily detached from the tube body 11. It is also possible to adopt a configuration in which this is omitted.

FIG. 4 is a cross-sectional view in which the main part is cut to explain the relationship between the tube body 11 with the cap adapter 20 attached and the internal structure and the relationship between the pair of electrode pins 24 and 24.
The base mounting portion 40 provided in the base adapter 20 has an annular flange 41. The depth of the annular flange 41 is equal to the length of the mounting body 14 provided on the base 13, and its diameter (inner diameter) is selected to be equal to the outer diameter of the mounting body 14. Since the main body of the base adapter 20 is fixed to the tube body 11 by the annular flange 41, it goes without saying that the attachment of the attachment barrel portion 14 to the annular flange 41 is not loosened.

  As shown in FIGS. 4 and 5, two holes 43, 43 are formed at predetermined locations on the bottom 42 of the base mounting part 40, and these holes 43, 43 insert the electrode pins 15. As shown in FIG. 4, when a pair of electrode pins 15 and 15 provided on the mounting body 14 are inserted, the holes are formed at positions facing them, and the electrode pins 15 and 15 The inner diameter is slightly larger than the 15 pin diameter.

  On the back side of the bottom portion 42, that is, the bottom rear surface side facing the adapter main body 21 side, as shown in FIGS. 4 and 5, electrode pieces 45 and 45 are respectively provided so as to protrude slightly into the pair of holes 43 and 43, respectively. As shown in FIG. 6, the contact is made with the electrode pin 15 inserted into the holes 43, 43, as shown in FIG. In order to attach the electrode pieces 45, 45 to the bottom part 42, the piece attachment pieces 48, 48 are integrally formed with the bottom part 42 at the attachment position of the electrode pieces 45, 45 on the back surface of the bottom part 42 as shown in FIG. The holes 44 and 44 in FIG. 5 are punched holes necessary for integral molding.

  An annular engagement portion (ring flange) 47 as shown in FIG. 6 is formed integrally with the bottom portion 42 on the back side peripheral surface of the bottom portion 42, and the base mounting portion 40 is attached to the adapter main body 21 using the annular engagement portion 47. It is fitted and fixed to the inner surface. Fixing screws 49, 49 are used as shown in FIG. 5 (not shown in FIG. 4) in order to make the fixing more firm.

  As shown in FIG. 4, an ion generator 30 is built in the adapter main body 21. In this example, an electron emission type (pulse discharge type) is used as the ion generator 30.

  The configuration of the electron emission type ion generator 30 is well known, and includes a discharge needle 31 acting as a negative electrode and a booster (boost circuit) 32 for applying a pulsed high voltage to the discharge needle 31. Composed. As the power source of the booster 32, a power source for LED lighting supplied from the electrode pins 24 and 24 via the socket 2 is used.

  Of course, the power from the socket 2 is also supplied to the LED drive circuit (not shown) in the tube 11 via (socket 2—electrode pins 24, 24—electrode segments 45, 45—electrode pins 15, 15). Wired as is done.

  As shown in FIGS. 4 and 7, only the distal end portion of the discharge cable acts as the discharge needle 31. A through-hole 22 is formed in a part of the peripheral wall of the adapter main body 21, and a hooked hollow cylinder 35 is fitted and fixed in the through-hole 22, so that the tip of the discharge needle 31 faces the hollow 35 a. Fixed. Attachment and fixation of the discharge needle 31 to the hollow cylinder 35 is performed by a cylindrical mounting member 34. The discharge needle 31 is fixed at a position that does not protrude outward from the hollow cylinder 35. In the figure, the hollow cylinder 35 is protruded only to about half or less of the depth.

  In addition, the thickness of the discharge needle 31 is about 0.3 to 0.4 mm, the inner diameter of the hollow cylinder 35 is about 3 to 4 mm, and the depth of the hollow cylinder 35 is about 3 to 4 mm.

  As shown in FIG. 4, the base adapter 20 configured as described above has the mounting body 14 mounted in the base mounting part 40 and is fitted and fixed to the tube body 11 by the engagement piece 50 in this state. When the fixture body 10B is mounted and fixed in the socket 2, the discharge needle 31 of the base adapter 20 faces the indoor space (illumination space). Therefore, when the lighting fixture 10 is attached to the ceiling, the discharge needle 31 faces directly below. It will be attached and fixed to.

  In the state of FIG. 4, the base adapter 20 is attached and fixed to the tube body 11, and the power source from the socket 2 is (socket 2 -electrode pin 24, 24 -electrode piece 45 -electrode pin 15, 15). Therefore, it is electrically conductive.

 Therefore, as shown in FIG. 1, when the tube body 11 and the base adapter 20 are inserted and fixed between the pair of sockets 2 and 2, the LED 18 is energized by turning on the power switch, and the LED 18 is turned on.

  At the same time, since a predetermined driving power is supplied to the ion generator 30, a pulsed high voltage is applied to the discharge needle 31 acting as a negative electrode, and directly into the air around the discharge needle 31. Electrons are emitted. As a result, electrons released into the air are combined with surrounding oxygen and moisture to form negative ions, and these negative ions are released into the indoor space to be sterilized and sterilized in the room. Since negative ions continue to be released into the room while the lighting apparatus 10 is in use, when the lighting apparatus 10 with the base adapter 20 is installed in the entire room, the indoor environment can be improved efficiently.

  This device can be used for a lighting apparatus that is installed and used on a ceiling in a hospital, office, or home.
