Description

  The present invention relates to a fluorescent lamp type LED lighting tube in which a plurality of LEDs are arranged, and an LED lighting device in which a plurality of the LED lighting tubes are connected. The present invention relates to an LED illuminating tube and an LED illuminating device suitable for illuminating products and products.

Conventionally, a fluorescent lamp illumination device has been used for indoor lighting.
The fluorescent lamp illuminating device has a fluorescent lamp fixture arranged in advance on a ceiling or the like, and a fluorescent lamp attached to the fluorescent lamp fixture as a light source.
There are various lighting methods for starting this fluorescent lamp. Typical examples include a glow start method using a glow starter (lighting tube), and a rapid start with a starting auxiliary conductor. There is a rapid start method that starts with a combination of a type lamp and a magnetic leakage transformer type ballast with preheating winding, and an inverter method using an inverter circuit.

In recent years, LED illumination tubes have attracted attention as light sources that can replace fluorescent lamps.
The LED illumination tube is configured to arrange LEDs in a transparent or translucent cylindrical tube at a predetermined interval, and to receive light from the external power supply so that the LEDs emit light.
This LED illumination tube has the same shape as that of a straight tube type fluorescent lamp as a whole. In addition, a base is provided at both ends of the cylindrical tube, and a plurality of (usually two) pins are projected from the base. Thereby, the LED illumination tube can be attached to an existing fluorescent lamp fixture.

By the way, as described above, there are various fluorescent lamp lighting methods, and all of them have a circuit configuration for lighting the fluorescent lamp.
For this reason, when attaching an LED illumination tube to the fluorescent lamp fixture, it was necessary to change to a circuit or wiring suitable for the LED illumination tube.
In addition, when a fluorescent lamp is attached again to a fluorescent lamp fixture whose circuit or the like has been changed, it is necessary to restore the circuit or the like.
Furthermore, if the LED lighting tube is mistakenly attached to a fluorescent lamp fixture whose circuit has been restored, the LED lighting tube may be damaged or burnt out.

In view of this, a technique has been proposed in which both the LED lighting tube and the fluorescent lamp can be attached to the same fluorescent lamp fixture without changing the wiring and the circuit.
For example, the bases provided at both ends of the LED lighting tube are used only to support the tube body, and for wiring for flowing current to the LED, one side is connected to the substrate on which the LED is mounted, There is one that takes in the commercial power from outside through the other side through a hole on the side of the tube (see, for example, Patent Document 1).
According to this technique, power is supplied to the LED through the newly installed wiring, not through the various lighting system circuits and wiring already installed in the fluorescent lamp fixture. For this reason, an LED lighting tube can be attached without changing those existing circuits. Moreover, since these circuits are not changed, a fluorescent lamp can be attached as it is.

Utility Model Registration No. 3119578

However, the technique described in Patent Document 1 described above has the following problems.
In this technology, when the LED lighting tube is attached to the fluorescent lamp fixture, the base of the LED lighting tube is engaged and fixed to the socket of the fluorescent lamp fixture, and the tube is rotated in a state where the base is fixed. Thus, the irradiation direction of light from the LED can be adjusted. That is, since the base is not fixed to the tubular body, the support of the tubular body by the base is unstable.

  In addition, among the prior arts related to LED lighting tubes, a fixing member such as a screw is used to attach the base at the end of the tubular body, a concave portion is provided on the base, and a convex portion is provided on the tubular body. There was something to fit. However, in these prior arts, the base has a pin for fitting into the socket of the fluorescent lamp fixture, and this pin is a circuit arranged in the fluorescent lamp fixture and an LED arranged inside the tube. To supply power to these LEDs. That is, the base of the prior art constitutes a part of a path for supplying power to the LED, and is not used only for supporting the tube. For this reason, the base cannot be removed from the tube, and it has been difficult to adjust the radiation direction of light outward from the tube.

  Furthermore, when connecting a plurality of conventional LED lighting tubes in a straight line, because there is a base at the connection location, the light emission surface in the tube is intermittently arranged, the light becomes discontinuous, Intermittently dark portions (unevenness) were formed on the light irradiation surface.

  The present invention has been considered in view of the above circumstances, and can be attached to a fluorescent lamp fixture. The base attached to both ends of the LED lighting tube is used only for supporting the tubular body, and light from the tubular body is used. It is an object of the present invention to provide an LED lighting tube and an LED lighting device that can adjust the radiation direction of the light source and can eliminate unevenness of light on the irradiation surface when a plurality of LED lighting tubes are linearly connected.

  In order to achieve this object, an LED lighting tube of the present invention is an LED lighting tube including a tube body having a circuit board on which a light emitting element is disposed, and a blocking member provided on an end surface of the tube body. And a base that is detachably attached to the outside of the closing member, and a power cord for supplying power to the light emitting element. One of the power cords is connected to the circuit board and the other is a tube. It is configured to be connected to the outside through a body or a blocking member.

  Moreover, the LED lighting device of the present invention is an LED lighting device in which a plurality of the above-mentioned LED lighting tubes are connected, and the attachment surface of the closing member to which the base is attached by removing the base from both ends of the LED lighting tube A plurality of LEDs by exposing the circular plane of the blocking member in one LED lighting tube and the circular plane of the blocking member in the other LED lighting tube. The illumination tube is connected in series.

According to the LED lighting tube and the LED lighting device of the present invention, since the power cord for supplying power to the light emitting element is connected to the outside via the tube or the blocking member, the power cord is connected to the path for supplying the power. No longer intervenes. Therefore, this base can be used only for supporting the tubular body.
Then, on the circular surface of the base, a plurality of holes are formed concentrically with the outer periphery, one hole is selected from the plurality of holes, and a fixing member is inserted into the selected hole to fix the base. By doing so, the radiation direction of the light from the tubular body can be adjusted to a desired direction.

Moreover, since the outer surface of the blocking member in the LED lighting tube is a flat surface, the blocking members of the plurality of LED lighting tubes can be brought into contact with each other without any gap, thereby forming a linear LED lighting device.
And the light emitted from the light emitting element inside a tubular body can be permeate | transmitted by forming a closure member with a transparent or semi-transparent material. Thereby, the light emitted from each of the plurality of LED illumination tubes connected in a straight line becomes continuous, and a dark portion (unevenness) can be eliminated on the surface (irradiation surface) receiving the light.

  Hereinafter, preferred embodiments of an LED lighting tube and an LED lighting device according to the present invention will be described with reference to the drawings.

[Embodiment of LED lighting tube]
First, an embodiment of the LED lighting tube of the present invention will be described with reference to FIG.
The figure is an external perspective view showing the overall configuration of the LED lighting tube of the present embodiment.

(Configuration of LED lighting tube)
As shown in the figure, the LED lighting tube 1 includes a tube body 10, a circuit board 20, a light emitting element 30, a power cord 40, a closing member 50, and a base 60.
Here, the tubular body 10 is a member having a hollow pipe shape and a circular cross section in the radial direction.
The tube body 10 can be formed of a material such as plastic or glass, for example.
Moreover, the tube body 10 can be formed entirely or partially from a transparent or translucent material. Here, when the tube body 10 is formed by combining two plate members formed in an arc shape, and the circuit board 20 is arranged so as to bridge each joint portion of these plate members, the circuit board 20 The plate member facing the surface on which the light emitting element 30 is disposed (the plate member on the side from which the light emitting element 30 emits light) can be transparent or translucent.

The circuit board 20 is a plate-like board disposed inside the tube body 10, and includes a plurality of light emitting elements 30 and an electronic circuit (not shown) for supplying a predetermined current to the light emitting elements 30. It is installed.
The electronic circuit is composed of a plurality of electronic components and wiring connecting them. Examples of the electronic component include a resistor for flowing a predetermined amount of current through the light emitting element 30 and a leveling capacitor for leveling the current flowing through the light emitting element 30.

The light emitting element 30 can be composed of, for example, an LED (Light Emitting Diode), and emits light when a voltage of a predetermined value or more is applied.
Note that the light emission range of the LED is limited to a certain solid angle range due to directivity characteristics. Usually, a range of a certain solid angle centered on a direction perpendicular to the surface of the circuit board 20 on which the light emitting element 30 is arranged is a light emission range.

One end of the power cord 40 is connected to a lamp side circuit (described later) disposed in the fluorescent lamp fixture 2, and the other end is connected to the circuit board 20 disposed inside the tube body 10. Yes. That is, the power cord 40 connects the lamp-side circuit disposed outside the LED lighting tube 1 and the circuit board 20 disposed inside the LED lighting tube 1. For this reason, a wiring insertion part for allowing the power cord 40 to pass is formed in the tube body 10 or the closing member 50 constituting the housing of the LED lighting tube 1.
In the wiring insertion part, for example, a notch 11 (see FIG. 2) formed in the end 14 of the tube 10, a hole (not shown) formed in the peripheral surface of the tube 10, There are formed holes (not shown).

As described above, one end of the power cord 40 is connected to the lamp side circuit. The lamp side circuit is a circuit disposed in the fluorescent lamp fixture 2, and a transformer (transformer) that steps down the voltage value of the commercial AC power supply to a predetermined voltage value, a rectifier circuit that converts AC to DC, A smoothing circuit for smoothing the rectified current is provided. The power cord 40 supplies the DC voltage and current output from the lamp side circuit to the electronic circuit and the light emitting element 30 disposed on the circuit board 20. However, when the electronic circuit disposed on the circuit board 20 operates by alternating current, the power cord 40 supplies an alternating voltage and current to the electronic circuit. In this case, the lamp side circuit is configured to output an alternating voltage and current suitable for the operation of the electronic circuit.
Further, one end of the power cord 40 and the electronic circuit can be connected on the surface of the circuit board 20 by soldering or the like.

As shown in FIG. 2, the closing member 50 is a lid for closing the opening 13 of the end surface 12 of the tube body 10. The closing member 50 includes a lid portion 51 formed in a disk shape having substantially the same diameter as the end surface 12 of the tube body 10 and a fitting portion 52 that is fitted into the opening 13 of the end surface 12 of the tube body 10. ing.
In the lid portion 51, a groove 51-2 is formed along the periphery of a surface (tube body facing surface 51-1) that faces the end surface 12 of the tube body 10. By fitting the end portion 14 of the tube body 10 into the groove 51-2, the lid portion 51 is attached to the end surface 12 of the tube body 10.

The fitting portion 52 is a portion formed to project outward from the tube-facing surface 51-1 of the lid portion 51. The fitting portion 52 is fitted into one opening (opening on the side where the light emitting element 30 is not disposed) with the circuit board 20 as a boundary among the openings 13 of the end face 12 in the tubular body 10.
In addition, a hole 53 is formed in the fitting portion 52 from the surface opposite to the tube-facing surface 51-1 (the cap-facing surface 51-3) toward the tip of the fitting portion 52. 71 is screwed.
Furthermore, the insertion part 52 is divided into two stages, upper and lower, and the hole 53 described above is formed between them. For this reason, when the screw 71 is screwed into the hole 53, the upper stage 52-1 of the fitting part 52 is pushed upward to push the circuit board 20, and the lower stage 52-2 of the fitting part 52 is pushed downward to cause the tube Press the body 10. Thereby, the insertion part 52 (blocking member 50) is prevented from coming off the tubular body 10.

One or more holes 53 can be formed in the lid portion 51 and the fitting portion 52.
Further, in the base facing surface 51-3, a concave portion 53-1 is formed along the opening periphery of the hole 53, and the head of the screw 71 is accommodated in the concave portion 53-1. Thereby, since the head of the screw 71 does not protrude from the base facing surface 51-3, it can be maintained that the base facing surface 51-3 is a flat surface.
Furthermore, in the present embodiment, the lid portion 51 and the fitting portion 52 are integrally formed. However, the present invention is not limited to the integral formation, and may be configured separately.

The base 60 is a member that is attached to the base-facing surface 51-3 of the closing member 50 and constitutes an end portion of the LED lighting tube 1 of the present embodiment.
The base 60 is formed in a cap shape, and has a top plate portion 61 formed in a disk shape having substantially the same diameter as the lid portion 51 of the closing member 50, and a cylindrical shape having substantially the same diameter as the top plate portion 61. And a cylindrical portion 62 formed on the surface. And the top plate part 61 is formed in one circular surface of this cylinder part 62, and the other circular surface of the cylinder part 62 is opening (opening surface 63).

The base 60 has the opening surface 63 of the cylindrical portion 62 and the base facing surface 51-3 of the closing member 50 facing each other, and the opening 51 of the base 60 is inserted into the groove 51-4 at the periphery of the base facing surface 51-3. By fitting the peripheral edge (the end of the cylindrical part 62) and screwing in the screw 72, it can be attached to the closing member 50.
Here, the screw 72 passes through the hole 64 of the top plate portion 61 and is screwed (engaged) into the female screw (attachment portion) 54 of the closing member 50. The hole 64 is formed in the thickness direction of the top plate portion 61. The female screw 54 is formed from the cap facing surface 51-3 of the lid portion 51 of the closing member 50 toward the tube facing surface 51-1.
Then, the base 60 can be attached to the closing member 50 by inserting the screw 72 into the hole 64 of the top plate portion 61 and screwing into the female screw 54 of the closing member 50. Further, the base 60 can be removed from the closing member 50 by removing the screw 72. By attaching and detaching these screws 72, the base 60 can be attached to and detached from the LED lighting tube 1.

Further, a plurality of holes 64 are formed in the top plate portion 61 (three in the present embodiment). In addition, the plurality of holes 64 (64-1 to 64-3) are formed on the circular surface 65 of the top plate portion 61 concentrically with the outer periphery of the circular surface 65, respectively. On the other hand, only one female screw 54 is formed on the lid 51 of the closing member 50.
For this reason, the attachment angle of the base 60 with respect to the closing member 50 can be changed depending on which of the plurality of holes 64 the screw 72 is passed through, so that the light of the LED lighting tube 1 attached to the fluorescent lamp fixture 2 can be changed. The radiation direction can be changed. The attachment of the cap 60 and the adjustment of the radiation direction of the light from the LED illumination tube 1 will be described in detail later in “Attachment of LED illumination tube and angle adjustment”.

Further, a pin 66 to be inserted into the hole 2-2 of the socket 2-1 of the fluorescent lamp device 2 is formed projectingly on the circular surface 65 outside the top plate portion 61.
Furthermore, a concave portion 67 is formed in the top plate portion 61, and a hole 64 is formed in the bottom surface of the concave portion 67. As a result, the head of the screw 72 does not protrude from the circular surface 65 of the top plate portion 61. Therefore, when the pin 66 is inserted into the hole 2-2 of the socket 2-1 of the fluorescent lamp device 2, the socket 2 is inserted. -1 and the top plate portion 61 of the base 60 can be inserted firmly.

A lid member 80 is fitted in the recess 67. Thereby, the recessed part 67 is obstruct | occluded.
In the present embodiment, the number of the holes 64 is three, but the number is not limited to three, and an arbitrary number of holes 64 can be formed.
Furthermore, in the present embodiment, the number of female screws 54 is one, but the number is not limited to one, and an arbitrary number can be drilled.
The screw 72 passes through the hole 64 formed in the base 60 and engages with the attachment portion (female screw 54) of the closing member 50 to fix the base 60 to the closing member 50. It has a function as a “member”.

(Attachment and angle adjustment of LED lighting tube)
As shown in FIG. 3, the LED lighting tube 1 of the present embodiment can be attached to an existing fluorescent lamp fixture 2a on a ceiling or the like. In addition, the figure has shown the case where the one LED lighting tube 1 is attached to the fluorescent lamp fixture 2a for 1 lamp | ramp.
At the time of attachment, the LED lighting tube 1 is attached such that the surface of the circuit board 20 on which the light emitting element 30 is disposed faces downward. In addition, the wiring insertion part through which the power cord 40 is passed is positioned above the tube body 10. Furthermore, in a state where the LED lighting tube 1 is attached to the fluorescent lamp fixture 2a, the two pins 66 of the LED lighting tube 1 are horizontally arranged inside the socket 2-1. The concave portion 67 and the hole 64 of the base 60 are located above the pin 66.

Also, as shown in FIGS. 4A to 4C, by passing the screw 72 through any hole 64 among the plurality of holes 64 (64-1 to 64-3) formed in the base 60, The radiation direction of the light emitted from the light emitting element 30 disposed inside the tube body 10 can be changed.
The base 60 is assumed to have three holes 64 (64-1 to 64-3). And the hole 64-2 located in the middle shall be located on the perpendicular bisector of the line which connects the location where the two pins 66 protrude in the circular surface 65 of this nozzle | cap | die 60. As shown in FIG. The other hole 64-1 is located at a position inclined from the vertical bisector by a predetermined angle (-θ ° counterclockwise about the center O of the circular surface 65 of the base 60). And Furthermore, the other hole 64-3 is located at a position inclined from the vertical bisector by a predetermined angle (+ θ ° clockwise around the center O of the circular surface 65 of the base 60). .

  Here, for example, as shown in FIG. 2A-2, among the three holes 64 (64-1 to 64-3), a screw 72 is passed through the hole 64-2 located in the middle, thereby When the base 60 is attached to the closing member 50, and the LED lighting tube 1 is attached to the fluorescent lamp fixture 2a, the female screw 54 of the closing member 50 is connected to the closing member 50 as shown in FIG. It is located above the center O of the base facing surface 51-3 and on a vertical line passing through the center O. And the circuit board 20 arrange | positioned inside the tubular body 10 becomes horizontal in the surface in which the light emitting element 30 was arrange | positioned. For this reason, the radiation direction of the light from the tube body 10 becomes a downward direction along the perpendicular from the arrangement surface (c-2 in FIG. 4).

  Moreover, as shown to the same figure (a-1), when the screw | thread 72 is passed through the hole 64-3 located in the right side among the three holes 64 (64-1 to 64-3), As shown in FIG. 2B-1, the female screw 54 is located above the center O of the cap-facing surface 51-3 of the closing member 50 and has a predetermined angle (rightward) from a vertical line passing through the center O. + Θ °). And the circuit board 20 arrange | positioned inside the tubular body 10 inclines the surface in which the light emitting element 30 was arrange | positioned only predetermined angle (+ (theta)). For this reason, the radiation direction of the light from the tube body 10 is perpendicular to the arrangement surface of the circuit board 20 (a direction inclined by a predetermined angle (+ θ °) with respect to a vertical line passing through the center O). (Fig. C-1).

  Furthermore, as shown to the same figure (a-3), when the screw | thread 72 is passed through the hole 64-1 located in the left side among the three holes 64 (64-1 to 64-3), As shown in FIG. 3B-3, the female screw 54 is located above the center O of the mouthpiece facing surface 51-3 of the closing member 50, and has a predetermined angle (left) from a vertical line passing through the center O. It is located at a position inclined by -θ °. And as for the circuit board 20 arrange | positioned inside the tubular body 10, the surface in which the light emitting element 30 was arrange | positioned incline only by the predetermined angle (-theta degree). For this reason, the radiation direction of the light from the tube body 10 is perpendicular to the arrangement surface of the circuit board 20 (a direction inclined by a predetermined angle (−θ °) with respect to a vertical line passing through the center O). (C-3 in the figure).

Thus, by selecting an arbitrary hole 64 from the plurality of holes 64 (64-1 to 64-3) formed in the base 60 and passing the screw 72 through the hole 64, The direction of light emission can be changed.
The predetermined angle θ can be set to 30 °, 35 °, or the like, for example.

  Moreover, although the LED lighting tube 1 of this embodiment can be attached to the fluorescent lamp fixture 2a for 1 lamp as shown in FIG. 3, the fluorescent lamp fixture 2 which can be attached is not restricted to one lamp. Alternatively, as shown in FIG. 5, it can be attached to a fluorescent lamp fixture 2b (reverse Fuji type) for two lamps. Also in this case, the radiation direction of light from the tube body 10 can be adjusted.

For example, as shown in FIGS. 5 and 6, one set of sockets 2- out of two sets of sockets 2-1 (2-11, 2-12) disposed in the fluorescent lamp device 2 b for two lamps. 11, the LED lighting tube 1 in which the screw 72 is passed through the hole 64-1 is attached (left side in FIG. 6), and the screw 72 is passed through the hole 64-3 in the other set of sockets 2-12. The LED lighting tube 1 is attached (right side of the figure).
Thereby, the radiation | emission direction of the light from LED lighting tube 1 becomes perpendicular | vertical downward with respect to a ceiling.

  In FIG. 6, the light emission direction from the LED lighting tube 1 is set to be vertically downward with respect to the ceiling. However, the direction is not limited to this, and any direction, for example, 30 ° It can also be a direction having an angle of 60 ° (35 ° or 70 °).

Further, the base facing surface 51-3 is formed in a flat surface. Accordingly, the base facing surface 51-3 in one LED lighting tube 1 and the base facing surface 51-3 in another LED lighting tube 1 can be brought into contact with no gap. Thereby, the several LED lighting tube 1 can be arrange | positioned continuously linearly.

The closing member 50 is made of a transparent resin. Thereby, since the light emitted from the light emitting element 30 passes through the blocking member 50, seamless illumination without a joint or unevenness in the irradiated light can be realized.
Further, the lid portion 51 of the closing member 50 is formed in a thin disk shape (for example, a thickness of 4 mm). Thereby, even if there is a difference between the transparency of the tubular body 10 and the transparency of the closing member 50, the unevenness of light due to the difference can be minimized.
Note that the cap facing surface 51-3 of the closing member 50 is a surface to which the cap 60 is attached in the embodiment of the LED lighting tube 1, and is formed in a circular plane. It corresponds to.

As described above, according to the LED lighting tube and the LED lighting device of the present embodiment, one of the power cords for supplying power to the light emitting element is connected to the circuit board, and the other is the tube body or the blocking member. Therefore, power can be supplied to the light emitting element without using a base. Therefore, the base can be used only for supporting the tubular body.
In addition, since the power is supplied to the light emitting element without going through the base, the LED lighting tube can be attached to the fluorescent lamp fixture without modifying or changing the circuit or wiring arranged in the existing fluorescent lamp fixture. .

Furthermore, the caps provided at both ends of the LED lighting tube are detachable, and a plurality of holes through which screws for attaching the caps are formed are formed concentrically with the outer periphery of the cap. The attachment angle of the base can be adjusted by passing a screw through the LED, and as a result, the emission angle of light from the LED illumination tube attached to the fluorescent lamp fixture can be adjusted.
Moreover, since the base is fixed to the closing member and the tube by the fixing member (screw), the support of the tube by the base is stabilized.
