Description

  The present invention relates to a base, a straight tube LED lamp, and an illumination device.

In recent years, LED lamps using LEDs (Light Emitting Diodes) as light sources have become widespread.
LED lamps have the advantage that the power consumption and carbon dioxide emissions can be significantly reduced and the product life can be greatly extended compared to conventional lighting fixtures. For this reason, straight tube LED lamps have attracted attention as lighting fixtures that replace conventional fluorescent lamps.

For the type that uses the existing fluorescent lamp fixtures with double-sided power supply as it is without any work on the ballast, work when attaching straight tube LED lamps to or removing them from the fluorescent fixtures. There is no denying the possibility that a person will touch the terminal of the base through which the current flows.
In order to cope with this problem, Patent Literature 1 includes an operating body that protrudes by an urging force on the outer surface of the base, and the operating body is positioned at a predetermined position by contact pressure with the socket when the terminal of the base is inserted into the socket. There has been proposed a straight tube type LED lamp having a built-in switch that conducts when it is pushed down.
In a state where the terminal of the base is not completely inserted into the socket, that is, in a state where the operating body is not pushed down to a predetermined position, it does not conduct, thereby ensuring safety at the time of attachment.
At the time of removal, the terminal of the base is removed from the socket, and at the same time, the operating body protrudes with an urging force and the switch is turned off.
The operating body is arranged at one location closer to the outer periphery than the terminal so that it can be adapted to the type of fluorescent lamp that rotates by inserting the terminal of the base on both sides of the straight tube type LED lamp into the groove of the socket at the same time. Yes.

There are various socket shapes for this type of fluorescent lamp fixture. In general, the surface into which the terminal of the base is inserted is often flat, but as shown in FIG. 17, there is also a convex type in which the surface into which the terminal of the base is inserted partially protrudes in the lamp longitudinal direction.
In FIG. 17 (a), reference numeral 150a denotes a socket body fixed on both sides of the lamp fixture 150, 151 denotes a support portion provided on the socket body 150a so as to be displaceable under a biasing force in the lamp longitudinal direction, and 152 denotes a support portion. The terminal insertion part which protruded in the lamp | ramp longitudinal direction from the part 151 is shown.
When a straight tube type LED lamp having a base described in Patent Document 1 is to be attached to such a convex socket, the terminal of the base 153 is connected to a terminal insertion portion as shown in FIGS. In the state inserted in 152, a gap g exists between the socket body 150 a and the base 153.
Since the operating body 154 is located in the gap g without being in contact with the terminal insertion portion 152, it remains protruding, and the switch is not turned on even after the terminal is inserted.

If the operating body 105 is lengthened so that the switch is turned on even when there is a gap g, the operating body 154 becomes too long compared to the length of the terminal, resulting in a decrease in product value due to poor appearance, and insertion of the terminal There is also a concern that the workability related to this will decrease.
When the application target is limited to other than the convex type socket, the range of use as a product is narrowed.

  The present invention has been made in view of such a current situation, and it is possible to improve safety and workability in attaching and detaching lamps, and to provide a base that can be applied regardless of the type of socket. Its main purpose.

In order to achieve the above object, the present invention is a base provided with a pair of terminals for power supply provided at an end of a rod-shaped lamp body and attached to a socket of a lamp fixture,

A cover member provided on the other end of the housing and covering the pair of protruding terminals;
A biasing member that biases the cover member in the protruding direction;
A switch for switching conduction between the pair of terminals and the lamp body;
With
The cover member is configured such that the pair of protruding terminals are exposed by the biasing force of the biasing member,
When the cover member is in a predetermined position, the switch is switched to a conductive state.

  According to the present invention, it is possible to improve safety and workability in attaching and detaching a lamp, and it can be applied regardless of the type of socket.

Embodiments of the present invention will be described below with reference to the drawings.
A first embodiment is shown in FIGS.
FIG. 1 is an exploded perspective view showing the appearance of the lighting device 200. The lighting device 200 includes a straight tube LED lamp 100 and a lighting fixture (hereinafter also referred to as “lamp fixture”) 150 to which the straight tube LED lamp 100 is attached.
The straight tube LED lamp 100 includes an elongated rod-shaped lamp body 5 and caps 1 a and 1 b provided at both ends of the lamp body 5.
The lamp fixture 150 is the same as an existing fixture for lighting a fluorescent lamp, and is a power supply terminal provided on the caps 1a and 1b of the straight tube LED lamp 100 in accordance with the hole positions of the sockets 150a and 150b. Is inserted and mounted.
After the terminal is inserted into the socket, when the operator turns on the switch built in the caps 1a and 1b, the commercial current supplied from the socket flows to the LED in the lamp body 5 through the terminal. The lamp body 5 is turned on.

As shown in FIG. 2, the lamp body 5 includes a cylindrical housing 2 having a semicircular cross section and a translucent cover 3.
The casing 2 is formed of a metal material having a high thermal conductivity in order to increase the heat dissipation efficiency, and the outer shape of the integral configuration of the casing 2 and the cover 3 is a cylindrical shape.
On the outside of the flat part of the housing 2 and inside the cover 3, an LED substrate 11 as a mounting substrate is fixed via an adhesive sheet 10 so as to face the cover 3.
The LED board 11 is an elongated rectangular printed board, and includes an LED board 11a and an LED board 11b.
A plurality of LEDs 12 a and 12 b as examples of semiconductor light emitting elements (light sources) having an EL effect are mounted on the LED substrates 11 a and 11 b at predetermined intervals in the longitudinal direction of the housing 2.

As shown in FIG. 3, an elongated rectangular power supply substrate 7 extending in the longitudinal direction of the casing 2 is disposed inside the flat portion of the casing 2. A plurality of components 9 are mounted at intervals in the longitudinal direction.
The power supply substrate 7 is fixed to the housing 2 with a clamp 15.
The current rectified to direct current by the electronic component 9 is supplied to the LED boards 11a and 11b through lead wires (not shown).
A current is supplied to the power supply substrate 7 through lead wires 6a and 6b extending from the connectors connected to the caps 1a and 1b.
A switch described later built in the caps 1a and 1b has a function of electrically connecting a terminal inserted into the socket and the lead wires 6a and 6b.

As shown in FIG. 4A, the base 1 a is attached to the end portion of the lamp body 5 at one end side, and the housing 21 from which the pair of terminals 20 a and 20 b protrudes from the other end side, and the other end side of the housing 21. And a cylindrical cover member 22 movably provided in the protruding direction of the pair of terminals 20a and 20b.
The housing 21 includes a base base portion 23 attached to the end of the lamp body 5 and a base front end portion 24 that supports the cover member 22.
Insertion holes 22a and 22b for a pair of terminals 20a and 20b are formed in the front end surface (bottom surface) 22c of the cover member 22.
As shown in FIG. 4B, two compression springs 25 as urging members are provided inside the base end portion 24, and the cover member 22 is paired with a pair of terminals 20 a by the urging force of the compression spring 25. , 20b is biased in the protruding direction.
Thus, in a state where no external force is applied to the cover member 22, the pair of terminals 20 a and 20 b are covered with the cover member 22 so that the tips thereof do not protrude from the bottom surface 22 c of the cover member 22.

As shown in FIG. 5A, when the cover member 22 is pushed in the axial direction of the lamp body 5, that is, into the base end portion 24, the pair of terminals 20a and 20b are exposed.
As shown in FIG. 6 (a), the integrated body of the base end portion 24 and the cover member 22 is pushed into a base portion 23 fixed to the end of the lamp body 5 with a screw so that it can be coupled by a one-touch operation. It has become.
Specifically, as shown in FIG. 4B and the like, the claw member 28a provided on the base front end portion 24 side engages with the annular convex portion on the base base portion 23 side. The base portion 23 is integrally coupled.
In the present embodiment, the coupling configuration by one-touch operation is provided on the base end portion 24 side, but it may be provided on the base base portion 23 side.
That is, the claw member 28 a is a member that couples both the base base portion 23 and the base front end portion 24 by elastic deformation, and can be provided on either the base base portion 23 or the base front end portion 24.

The base end portion 24 includes a pair of terminals 20 a and 20 b as shown in FIG. 6B, and a rotational position of the base end portion 24 with respect to the switch holder 26 inserted into the cover member 22 and the base base portion 23. A rotation stopper member 27 for restricting the rotation, a coupling member 28 having a claw member 28a, and an annular switch operation member 29 fitted to the coupling member 28.
The cover member 22 has two claw members 22a. When the claw member 22a is engaged with the edge 26a of the switch holder 26, the cover member 22 is integrated with the switch holder 26, and the cover member 22 is also integrated. The protruding position of is regulated.

As shown in FIG. 6C, the switch holder 26 includes a cylindrical member 30 having a pair of terminals 20a and 20b.
The cylindrical member 30 includes a connector holder 32 that holds a connector having lead wires 6a and 6b, and a second terminal that contacts and separates from the pair of terminals 20a and 20b as first terminals. A second terminal member 31 that rotates in synchronization with the rotation operation of the member 29 and a torsion spring 33 that applies a biasing force to return the switch operation member 29 to the switch OFF position are accommodated.
Fig.7 (a) shows the whole nozzle | cap | die 1a, FIG.7 (b) has shown the longitudinal cross-section.

8A and 8B show the switch OFF state, and FIGS. 8C and 8D show the switch ON state.
As shown in FIG. 8A, the switch operating member 29 for turning on and off the switch is integrally formed with operation pieces 29a and 29b extending in the protruding direction of the terminals 20a and 20b, and the switch operating member 29 is rotated. Then, the second terminal member 31 rotates through the operation pieces 29a and 29b.
As shown in FIG. 8B, the second terminal member 31 has second terminals 31a and 31b connected to the lead wire 6a. When the switch operating member 29 is set to the OFF position, the contact piece 20a-1 and the second terminal 31a connected to the terminal 20a, and the contact piece 20b-1 and the second terminal 31b connected to the terminal 20b are They are separated from each other.
As shown in FIGS. 8C and 8D, when the switch operating member 29 is turned to the switch ON position, the contact piece 20a-1 connected to the terminal 20a, the second terminal 31a, and the terminal 20b are connected. The contact piece 20b-1 and the second terminal 31b are brought into contact with each other, and the pair of terminals 20a and 20b and the lead wire 6a are electrically connected and conducted.

FIGS. 8C and 8D are cross sections taken along the CC plane of FIG. 7B.
The switch operating member 29 and the second terminal member 31 constitute a switch in the present embodiment.

The dimensions of the base 1a, such as the outer diameter of the cover member 22, are dimensions corresponding to the JIS standard for fluorescent lamps.
That is, the outer diameter of the base end portion 24 is 25.78 mm or less and the length is 8.71 mm or more. Therefore, it corresponds to the fluorescent lamp standard of φ26 of JIS standard.
As shown in FIG. 8 (b), the shortest spatial distance w between the first terminals 20a and 20b and the second terminals 31a and 31b when the switch is OFF is set to 3 mm or more, which satisfies the standard as a switch. Yes.

Since the cover member 22 has a cylindrical shape and a distal end surface 22c thereof is a flat surface, the cover member 22 is also suitable for a convex socket from which the terminal insertion portion 152 protrudes as shown in FIG.
When the terminals 20a and 20b are aligned and pushed into the terminal insertion holes of the terminal insertion portion 152, the cover member 22 moves inward in the axial direction of the lamp body 5 in the direction opposite to the protruding direction, and relatively the terminals 20a and 20b. Only enters the terminal insertion hole of the terminal insertion portion 152.
Since the front end surface 22c of the cover member 22 is a flat surface, unlike the configuration in which the front end surface 22c projects partially like the operation body of Patent Document 1, some of the front end surface 22c comes into contact with the socket side. The retraction movement of the cover member 22 by the pressing and the relative protruding operation of the terminals 20a and 20b are obtained.
Thereby, it can be used regardless of the type of socket.

The shape of the front end surface 22c of the cover member 22, that is, the surface that comes into contact with the socket side when mounted, is not limited to a flat surface.
Whatever shape the socket side is, it may be any shape as long as it contacts somewhere on the socket side when it is mounted, and the cover member 22 can be retracted and moved with the pushing operation after the contact.

When the cover member 22 protrudes to cover the pair of terminals 20a and 20b, the switch operation member 29 is forcibly set to the OFF (off; non-conduction) position by the urging force of the torsion spring 33. ing.
Even if the operator pushes down the cover member 22 to expose the terminals 20a and 20b and touches the terminals 20a and 20b, the switch does not turn on by itself, so no current flows.
The cover member 22 has a double safety structure that prevents the operator from coming into contact with the member through which electricity flows because the switch member 29 is rotated and set to the switch ON position before electricity flows. It can be said that it is a member forming the first stage.

In the present embodiment, the cover member 22 covers the entire terminals 20a and 20b in the switch OFF state. However, in order to facilitate alignment with the terminal insertion holes on the socket side, one of the terminals 20a and 20b is used. You may make it cover in the state which the part protruded.
In the configuration in which the cover member 22 covers the entire terminals 20a and 20b, a mark for displaying the terminal position may be formed on the side surface of the cover member 22 to facilitate the mounting operation.

Based on FIG. 10 thru | or FIG. 12, the switch structure interlock | cooperated with the movement of the cover member 22 is demonstrated.
FIG. 10A shows a state in which the switch is OFF, and an arrow indicates a direction in which the urging force of the torsion spring 33 acts. At this time, the cover member 22 protrudes and covers the pair of terminals 20a and 20b.
FIG. 10B shows a state in which the switch is ON, and an arrow indicates a direction in which the rotational operation force of the switch operation member 29 is applied.
When the switch operating member 29 is rotated against the urging force of the torsion spring 33, the claw portion 33a of the torsion spring 33 gets over and engages with the protrusion 22d provided on the cover member 22.
At the same time, the protrusion 31 c formed on the second terminal member 31 gets over the protrusion 22 e provided on the cover member 22 and engages.

FIG. 11A shows a state in which the switch is ON, that is, a state in which the switch is attached to the socket. At this time, the claw portion 33a of the torsion spring 33 is engaged with the protrusion 22d of the cover member 22, and the protrusion 31c of the second terminal member 31 is engaged with the protrusion 22e of the cover member 22 as shown in FIG. doing.
Thereby, unless the nozzle | cap | die 1a is removed from a socket, it becomes possible to maintain the switch operation member 29 in an ON position.

As shown in FIGS. 11B and 12B, when the base 1a is removed from the socket, the cover member 22 protrudes by the urging force of the compression spring 25 in accordance with the operation.
When the protrusion 22d moves in synchronization with the protrusion operation of the cover member 22 and the cover member 22 protrudes completely as shown in FIG. 11C, the engagement between the protrusion 22d and the claw portion 33a of the torsion spring 33 is performed. Come off.
At the same time, as shown in FIG. 12C, the engagement between the protrusion 22e and the protrusion 31c of the second terminal member 31 is released.
Accordingly, the switch operation member 29 is automatically rotated to the switch OFF position by the urging force of the torsion spring 33.

The switch operation member 29 can be rotated regardless of the position of the cover member 22. However, in order to set the switch operating member 29 to the switch ON position, the claw portion 33a of the torsion spring 33 and the protrusion 31c of the second terminal member 31 are respectively covered with the cover member. A predetermined external force (rotational operation force) for getting over the protrusions 22d and 22e of 22 must be applied.
As long as a predetermined rotational operation force is not applied, the switch operation member 29 is maintained at the OFF position.
For this reason, the switch operating member 29 is not set to the ON position by vibration or the like after the straight tube LED lamp 100 is mounted on the lamp fixture 150.

In addition, when the straight tube LED lamp 100 is mounted on the lamp fixture 150, the switch operating member 29 is not unexpectedly set to the ON position by the hand-holding force of the operator.
Even if the switch operating member 29 is unexpectedly turned to the ON position before the operator wears it, the engagement is not maintained in the ON position when the cover member 22 is protruding, so the moment the hand is released. The switch operating member 29 returns to the OFF position.
Coupled with the fact that the direction in which the cover member 22 is pushed down is different from the direction in which the switch operating member 29 is set to the ON position, the condition that the operator contacts the member through which electricity is flowing during the mounting operation of the straight tube LED lamp 100. It doesn't happen unless it is done intentionally.

Based on FIG. 13 thru | or FIG. 15, the structure which can set the irradiation surface of LED in arbitrary positions is demonstrated.
As shown in FIG. 4B, one end of the compression spring 25 is fitted in the spring receiving portion 27 a of the rotation stopper member 27. For this reason, the rotation stopper member 27 is biased toward the base portion 23 by the compression spring 25.
As shown in FIG. 13 (a), the integrated body of the base end portion 24 and the cover member 22 is pushed into the base base portion 23 fixed to the end portion of the lamp body 5, thereby providing the base end portion 24 side. The claw member 28a thus engaged engages with the annular convex portion on the base base portion 23 side.
Thereby, the nozzle | cap | die front-end | tip part 24 and the nozzle | cap | die base part 23 are integrally couple | bonded by one-touch operation. FIG. 13B shows a cross-section after bonding.

As shown in FIG. 13 (b), the base end portion 24 can rotate in any of the left and right circumferential directions with respect to the base portion 23.
As shown in FIG. 6B, the rotation stopper member 27 that allows the circumferential rotation of the base end portion 24 has operation pieces 27 b on both sides, and the operation pieces 27 b are formed in the guide grooves 28 b of the coupling member 28. It is fitted and exposed on the outer surface of the base end portion 24.
The rotation stopper member 27 also has a bifurcated engagement portion 27c extending in the opposite direction to the operation piece 27b.
FIG. 14A shows a state where the operation piece 27 b of the rotation stopper member 27 is accommodated in the guide groove 28 b of the coupling member 28. In this state, as shown in FIG. 14 (d), the engaging portion 27 c of the rotation stopper member 27 is engaged with the rib 23 a of the base portion 23, and the base end portion 24 is rotated with respect to the base portion 23. I can't let you.

As shown in FIG. 14 (b), when the rotation stopper member 27 is pushed down to the cover member 22 side via the operation piece 27b against the urging force of the compression spring 25, the rib 23a and the rib 23a as shown in FIG. The engagement with the engagement portion 27c is released.
As shown in FIG. 14C, the base end portion 24 is turned to a desired irradiation surface position with the rotation stopper member 27 pushed down, and the operation piece 27b is released. When the rotation stopper member 27 returns to the original state by the urging force of the compression spring 25, the engaging portion 27c is engaged with the rib 23a again, and the base end portion 24 is locked to the base base portion 23 for rotation.
Marks M1 and M2 for determining the rotational position of the base end portion 24 with respect to the base base portion 23 are formed on the base base portion 23 and the switch operating member 29 of the base end portion 24, and are positioned at a predetermined angle. It can be done.

FIG. 15A shows a state in which the base end portion 24 is set at a reference position of 0 ° with respect to the base base portion 23. The rotation angle of the base end portion 24 is ± 90 ° at the maximum in the left-right direction.
As shown in FIG. 15B, when the base end portion 24 is rotated to the right by −90 °, the protruding edge 30a of the cylindrical member 30 hits the rib 23a of the base portion 23 as shown in FIG. No more can be rotated. The operation piece 27b shown in FIG. 15B is the other operation piece located on the opposite side to the operation piece 27b in FIG.
When the base end 24 is rotated + 90 ° to the left with reference to the position of FIG. 15A, the protruding edge 30a of the cylindrical member 30 hits the rib 23a of the base 23 as shown in FIG. 15C. No more can be rotated.

In the present embodiment, the angle of the irradiated surface can be adjusted in seven stages of 30 ° steps.
By adopting a configuration that cannot rotate beyond a certain angle, there is an effect of preventing the harness in the base from being twisted and broken more than necessary.
The configuration, operation, and operation of the base 1a described above are the same in the other base 1b.

In the above embodiment, the cover member 22 is not electrically connected only by being pushed in, and the switch operation member 29 has to be rotated. However, as shown in FIG. 16, the cover member 22 is moved to a predetermined position. It is good also as a structure which turns on a switch, when it pushes in (2nd Embodiment).
As shown in FIG. 16A, the cover member 22 is integrally provided with second terminals 32a and 32b. When the cover member 22 is pushed into a predetermined position, that is, attached to the socket, as shown in FIG. 16B, the second terminals 32a and 32b are electrically connected between the pair of terminals 20a and 20b and the lead wire 6a. Connect to.

In each of the above embodiments, the bases 1a and 1b attached to both ends of the lamp body 5 have the same configuration, but the bases may have different bases at one end and the other end.
For example, the base on one end side of the lamp body 5 may be easily mounted with the terminal always protruding, and the base on the other end side may be the above-described highly safe base.
That is, the straight tube LED lamp according to the present invention only needs to have the base having the above-described configuration at least at one end portion of the lamp body 5.

The preferred embodiments of the present invention have been described above. However, the present invention is not limited to such specific embodiments, and unless specifically limited by the above description, the present invention described in the claims is not limited. Various modifications and changes are possible within the scope of the gist.
