Description

  The present invention relates to a socket to which a straight tube type LED lamp is attached, and particularly to a socket corresponding to a single tube type straight tube type LED lamp.

  Conventionally, straight-tube fluorescent lamps have been the mainstream for lighting used in offices and factories, but recently, straight-tube fluorescent lamps have been replaced with direct-current fluorescent lamps against the background of demand for power saving and technological advances. The movement to replace tube LED lamps is accelerating. A straight tube type LED lamp is a straight tube similar to the tube of a straight tube fluorescent lamp, in which a substrate on which a large number of LED (Light Emitting Diode) chips are mounted is housed in a straight tube. Compared with a tube-type fluorescent lamp, it has a feature of low power consumption and long life.

  Similar to the straight tube fluorescent lamp, such a straight tube type LED lamp has a base at the end of the tube body, and a pair of electrode pins protrude from the base. At present, the interval between the electrode pins is the same as the interval between the electrode pins of the straight tube fluorescent lamp. Therefore, when replacing the straight tube type fluorescent lamp with a straight tube type LED lamp, the straight tube type fluorescent lamp is used. A straight tube type LED lamp can be mounted using a lamp socket. As a socket for a straight tube fluorescent lamp, a socket corresponding to a G13 base defined by Japanese Industrial Standards (JIS C7601) (hereinafter referred to as “G13 base socket”) is generally used.

  However, since the driving method is fundamentally different between fluorescent lamps and LED lamps, when a straight tube type LED lamp is mounted on an existing G13 base socket, in order to perform a predetermined power supply to the straight tube type LED lamp. Construction such as changing the wiring and installing the power supply unit is necessary.

  Nowadays, straight tube LED lamps with various specifications are released by many manufacturers, but the straight tube LED lamps currently supplied to the market are mainly classified into the following three types.

(Type 1)
A type that can be used with a ballast for fluorescent lamps connected. It is a straight-tube LED lamp of a double-sided power feeding system that incorporates a power source for LEDs and feeds power from electrode pins on both sides. In this type, it is not necessary to separate the ballast when attaching to the existing G13 base socket.

(Type 2)
A type that uses a ballast separately, and a power supply for LED is provided outside the lamp. As a power feeding method, there are a both-side power feeding method in which power is fed from the electrode pins on both sides and a one-side power feeding method in which power is fed from the electrode pins on one side. In any system, the power supply voltage is DC (direct current). In this type, when it is attached to the existing socket for the G13 base, it is necessary to change the wiring accompanying the ballast separation and to install the power supply unit.

(Type 3)
A type that uses a ballast separately and has a built-in LED power supply. As a power feeding method, there are a both-side power feeding method in which power is fed from the electrode pins on both sides and a one-side power feeding method in which power is fed from the electrode pins on one side. In any method, the power supply voltage is AC (alternating current). This type requires wiring change work that accompanies ballast disconnection.

  As described above, there are various types of straight tube LED lamps. However, the one-side power feeding method of type 2 and the one-side power feeding method of type 3 have the following problems.

  In the case of a single-side power supply type straight tube type LED lamp, the LED lamp can be attached to the socket by performing wiring work for one-side power supply to the existing G13 base socket. However, when the wiring work is completed, the power source is directly connected to the terminal of the G13 base socket on one side without going through the ballast. Therefore, when a straight tube type fluorescent lamp is attached to the socket, which is mistaken for a straight tube type LED lamp, a filament electrode as a conductor is connected between the electrode pins of the fluorescent lamp, so that the power supply is short-circuited. Fire occurs.

  As a countermeasure against such a short circuit accident due to erroneous mounting, there is a “straight tube type LED lamp system with an L-shaped base” according to the standards of the Japan Light Bulb Industry Association (JEL801: 2010). This is because the shape of the lamp-side electrode pin is L-shaped, and the socket-side terminal is made to correspond to the L-shaped pin. By eliminating compatibility with the G13 cap, This is to prevent wearing. However, this standard is a DC-specific standard, and the shape of the lamp-side electrode pin must be changed to an L shape, which increases the burden on the manufacturer.

  On the other hand, Patent Document 1 below describes an adapter for preventing different types of fluorescent lamps from being erroneously attached to a socket. The adapter is provided with a slit, and the slit width is smaller than the diameter of the electrode pin of the old fluorescent lamp and larger than the diameter of the electrode pin of the new fluorescent lamp. By attaching this adapter to the existing socket, only the new fluorescent lamp can be mounted, and erroneous mounting of the old fluorescent lamp is prevented. However, this requires an adapter separately from the socket, which increases the cost burden for the user.

  Further, Patent Document 2 below describes a socket provided with a stopper convex portion that prevents different types of fluorescent lamps from being erroneously attached to the socket. In this socket, when a fluorescent lamp with a small tube diameter is mounted, the stopper convex part does not contact the lamp, and when a fluorescent lamp with a large tube diameter is mounted, the stopper convex part contacts the lamp. Incorrect mounting of fluorescent lamps with a large tube diameter is prevented. However, this method cannot prevent erroneous mounting when the tube diameters of different types of fluorescent lamps are the same.

JP 2005-317527 A JP-A-8-124416

  As described above, since current measures against short-circuit accidents due to incorrect mounting of lamps are not sufficient, measures that can prevent erroneous mounting of lamps simply and reliably are desired.

  The present invention meets these requirements, and an object of the present invention is to provide a straight tube type LED lamp socket capable of reliably preventing erroneous mounting of the lamp by simple means.

  The straight tube type LED lamp socket according to the present invention includes a socket body, a pair of pin insertion holes into which a pair of electrode pins protruding from the base of the straight tube type LED lamp are inserted, and the pin insertion holes inserted into the pin insertion holes. A contact for contacting the electrode pins is provided, and the pin insertion holes are provided at intervals different from the intervals between the electrode pins of the straight tube fluorescent lamp.

  In this way, when a straight tube type LED lamp is installed after the existing socket is constructed, the interval between the pin insertion holes of the socket corresponds to the interval between the electrode pins of the LED lamp. Therefore, the LED lamp can be normally attached to the socket. On the other hand, even if a straight tube type fluorescent lamp is mistakenly attached to a straight tube type LED lamp and the interval between the pin insertion holes of the socket is different from the interval between the electrode pins of the fluorescent lamp, the electrode pin is inserted. Cannot be inserted into the hole. Thereby, erroneous mounting of the fluorescent lamp can be reliably prevented. In addition, the electrode pins of the straight tube type LED lamp may have a conventional shape and do not need to be changed to a special shape. Furthermore, an adapter as described in Patent Document 1 is also unnecessary.

  In the first embodiment of the present invention, the pin insertion hole of the socket corresponds to the electrode pin of an AC power supply type straight tube LED lamp, and the interval between the pin insertion holes is that of the electrode pin of the straight tube fluorescent lamp. It is larger than the interval.

  In the second embodiment of the present invention, the pin insertion hole of the socket corresponds to the electrode pin of the direct current type LED lamp of the DC power feeding method, and the interval of the pin insertion hole is the electrode pin of the straight tube type fluorescent lamp. It is smaller than the interval.

  A straight tube type LED lamp socket according to the present invention includes a lead wire that is electrically connected to a contact and is led out from the socket body, and a power supply connection terminal provided at an end of the lead wire that is led out. And may be provided. If it does in this way, when performing wiring change construction, a power supply can be easily connected to a socket using the connection terminal for electric power feeding, and work efficiency can be attained.

  According to the present invention, when replacing a straight tube type fluorescent lamp with a straight tube type LED lamp, it is possible to reliably prevent erroneous installation of the straight tube type fluorescent lamp after completion of construction by a simple means, and a short circuit accident. It becomes possible to prevent ignition due to.

It is a figure which shows 1st Embodiment of this invention. It is a figure which shows 2nd Embodiment of this invention. It is a figure which shows a straight tube | pipe type fluorescent lamp and its socket. It is a side view of the socket for straight tube | pipe type LED lamps.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, the same reference numerals are given to the same parts or corresponding parts.

(First embodiment)
FIG. 1 shows a first embodiment of the present invention. (A) is a perspective view of a main part of a straight tube type LED lamp and its socket, (b) is a plan view of a base part of the straight tube type LED lamp, and (c) is a front view of a main part of the socket. The first embodiment is directed to a socket suitable for an AC power supply type straight tube LED lamp.

  In FIG. 1A, a straight tube type LED lamp (hereinafter simply referred to as “LED lamp”) 100 protrudes from a tube body 101, a cap 102 provided at an end of the tube body 101, and the cap 102. A pair of electrode pins 103 and 104 are provided. This LED lamp 100 is, for example, a 40 W / AC 100 V specification and is a one-side power feeding type power supply built-in type (type 3 described above). Inside the tube body 101, a substrate on which a large number of LED chips are mounted and a power circuit for LEDs are housed (not shown). The power supply circuit is composed of an AC / DC converter, converts AC100V fed to the electrode pins 103 and 104 into direct current, supplies direct current to the LED, and causes the LED to emit light.

  A straight tube type LED lamp socket (hereinafter simply referred to as a “socket”) 10 includes a socket body 11 and a pair of pin insertion holes 12 and 13 provided in the socket body 11. The socket body 11 has the same shape as the socket for the G13 base. A pair of electrode pins 103 and 104 of the LED lamp 100 are inserted into the pin insertion holes 12 and 13. Therefore, the distance between the pin insertion holes 12 and 13, that is, the distance X shown in FIG. 1C is equal to the distance between the electrode pins 103 and 104, that is, the distance X shown in FIG.

  Here, the interval X between the pin insertion holes 12 and 13 is set larger than the interval Y between the electrode pins 303 and 304 of the straight tube fluorescent lamp (hereinafter simply referred to as “fluorescent lamp”) 300 shown in FIG. . 3A to 3C correspond to FIGS. 1A to 1C, and the respective parts 301 to 304 of the fluorescent lamp 300 correspond to the respective parts 101 to 104 of the LED lamp 100. is doing. The socket 30 is a G13 base socket, and each part 31 to 33 of the socket 30 corresponds to each part 11 to 13 of the socket 10.

  As an example, when the electrode pin interval Y of the fluorescent lamp 300 is 12.7 mm, the interval between the pin insertion holes 32 and 33 of the socket 30 is also 12.7 mm, but the pin insertion hole 12 of the socket 10 of the first embodiment. , 13 is set to 14.7 mm, which is 2 mm larger than that, for example. Therefore, the electrode pin interval X of the LED lamp 100 is also 14.7 mm.

  When the fluorescent lamp 300 is replaced with the LED lamp 100, the fluorescent lamp socket 30 is replaced with the LED lamp socket 10, and the wiring is changed. In this construction, the ballast (not shown) is disconnected, and the wiring is changed so that an AC power supply is connected to a terminal (described later) of the socket 10.

  When the wiring change work is completed, the LED lamp 100 is attached to the socket 10. In this case, since the interval X between the electrode pins 103 and 104 of the LED lamp 100 is the same as the interval X between the pin insertion holes 12 and 13 of the socket 10, the electrode pins 103 and 104 are inserted into the pin insertion holes 12 and 13, The LED lamp 100 can be normally attached by electrically connecting with a contact (described later) in the insertion hole. After attachment, 100 VAC is supplied to the electrode pins 103 and 104, and the LED lamp 100 is lit by the one-side power supply method.

  On the other hand, even if the fluorescent lamp 300 is mistakenly attached to the socket 10 after the wiring change work is completed, the distance X between the pin insertion holes 12 and 13 (see FIG. 1C) is determined by the electrode of the fluorescent lamp 300. Since the distance Y between the pins 303 and 304 (see FIG. 3B) is larger, the electrode pins 303 and 304 cannot be inserted into the pin insertion holes 12 and 13. Therefore, it becomes impossible to attach the fluorescent lamp 300 to the socket 10, and erroneous mounting of the lamp can be reliably prevented.

  In this way, by making the interval X between the pin insertion holes 12 and 13 different from the interval Y between the electrode pins 303 and 304 of the fluorescent lamp 300, the socket 10 becomes a dedicated socket (AC type) for the LED lamp 100, and fluorescent light is emitted. It is possible to prevent erroneous attachment of the lamp 300 and prevent ignition due to a short circuit accident. Further, the electrode pins 103 and 104 of the LED lamp 100 may have a conventional shape, and it is not necessary to change the shape to an L shape. Therefore, the manufacturer can cope with the change by simply changing the distance between the electrode pins. Furthermore, since no adapter is required, the cost burden on the user side does not increase. Therefore, according to the present embodiment, erroneous mounting of the lamp can be reliably prevented by simple means.

(Second Embodiment)
FIG. 2 shows a second embodiment of the present invention. (A) is a perspective view of a main part of a straight tube type LED lamp and its socket, (b) is a plan view of a base part of the straight tube type LED lamp, and (c) is a front view of a main part of the socket. The second embodiment is directed to a socket that is suitable for a direct current type LED lamp of a DC power feeding method.

  2A, the LED lamp 200 includes a tube body 201, a base 202 provided at an end of the tube body 201, and a pair of electrode pins 203 and 204 protruding from the base 202. . The LED lamp 200 is, for example, a 40 W / DC 50 V specification and is a one-side power feeding type external power supply type (type 2 described above). A substrate on which a large number of LED chips are mounted is housed inside the tube body 201 (not shown). An external power supply unit (not shown) is composed of an AC / DC converter, converts AC 100V into direct current, supplies direct current to the LED via the electrode pins 203 and 204, and causes the LED to emit light.

  The socket 20 includes a socket body 21 and a pair of pin insertion holes 22 and 23 provided in the socket body 21. The socket body 21 has the same shape as the socket for the G13 base. A pair of electrode pins 203 and 204 of the LED lamp 200 are inserted into the pin insertion holes 22 and 23. Therefore, the interval between the pin insertion holes 22 and 23, that is, the interval X shown in FIG. 2C is equal to the interval between the electrode pins 203 and 204, that is, the interval X shown in FIG.

  Here, the interval X between the pin insertion holes 22 and 23 is set smaller than the interval Y between the electrode pins 303 and 304 of the fluorescent lamp 300 shown in FIG.

  As an example, when the electrode pin interval Y of the fluorescent lamp 300 is 12.7 mm, the interval between the pin insertion holes 32 and 33 of the socket 30 is also 12.7 mm, but the pin insertion hole 22 of the socket 20 of the second embodiment. , 23 is set to 10.7 mm, which is 2 mm smaller than that, for example. Therefore, the electrode pin interval X of the LED lamp 200 is also 10.7 mm. In the second embodiment, since the power supply voltage is lower (DC50V) than in the case of the first embodiment (AC100V), there is no problem even if the interval X is reduced.

  When replacing the fluorescent lamp 300 with the LED lamp 200, the fluorescent lamp socket 30 is replaced with the LED lamp socket 20, and the wiring change work and the power supply unit installation work are performed. In this construction, the ballast (not shown) is disconnected, and the wiring is changed so that the power supply unit (DC power supply) is connected to the terminal (described later) of the socket 20.

  When the wiring change work is completed, the LED lamp 200 is attached to the socket 20. In this case, since the interval X between the electrode pins 203 and 204 of the LED lamp 200 is the same as the interval X between the pin insertion holes 22 and 23 of the socket 20, the electrode pins 203 and 204 are inserted into the pin insertion holes 22 and 23, The LED lamp 200 can be normally attached by being electrically connected to a contact (described later) in the insertion hole. After the attachment, DC 50V is supplied to the electrode pins 203 and 204, and the LED lamp 200 is lit by the one-side power supply method.

  On the other hand, even if the fluorescent lamp 300 is mistakenly attached to the LED lamp 200 after the wiring change work is completed, the distance X between the pin insertion holes 22 and 23 (see FIG. 2C) is determined by the electrode of the fluorescent lamp 300. Since the distance Y between the pins 303 and 304 (see FIG. 3B) is smaller, the electrode pins 303 and 304 cannot be inserted into the pin insertion holes 22 and 23. Therefore, it becomes impossible to attach the fluorescent lamp 300 to the socket 20, and erroneous mounting of the lamp can be reliably prevented.

  In this way, by making the interval X between the pin insertion holes 22 and 23 different from the interval Y between the electrode pins 303 and 304 of the fluorescent lamp 300, the socket 20 becomes a dedicated socket (DC type) for the LED lamp 200, and fluorescent light is emitted. It is possible to prevent erroneous attachment of the lamp 300 and prevent ignition due to a short circuit accident. In addition, the electrode pins 203 and 204 of the LED lamp 200 may have a conventional shape and do not need to be changed to a shape such as an L shape. Therefore, the manufacturer can cope with the change by simply changing the distance between the electrode pins. Furthermore, since no adapter is required, the cost burden on the user side does not increase. Therefore, according to the present embodiment, erroneous mounting of the lamp can be reliably prevented by simple means.

  FIG. 4 is a side view showing a schematic structure of the socket 10 (FIG. 1). A contact 14 is provided inside the socket body 11. This contact 14 is comprised from the metal plate which has elasticity. One end of the contact 14 faces the pin insertion hole 13 as a pin contact portion 15, and the other end of the contact 14 is fixed to the terminal 16. When the electrode pin 104 (FIG. 1) is inserted into the pin insertion hole 13, the pin contact portion 15 is pushed and displaced by the electrode pin 104, and the electrode pin 104 and the pin contact portion 15 are pressed against each other due to the elasticity of the contact 14. At the same time, both are electrically connected.

  A lead wire 50 is connected to the terminal 16. The lead wire 50 is led out from the socket body 11, and a connecting terminal 51 for feeding is provided at the end of the lead wire 50 led out. The connection terminal 51 is a crimp terminal, for example, and is covered with a vinyl cover 52 for insulation. A connector (not shown) provided at the end of the power cable is connected to the connection terminal 51 at the time of wiring change work, and power is supplied from the power source to the LED lamp 100 via the lead wire 50 and the contact 14. Done.

  In this way, by attaching the lead wire 50 having the power supply connection terminal 51 to the socket 10, the power supply can be easily connected to the socket 10 using the connection terminal 51 when performing the wiring change work. It is possible to improve work efficiency. In addition, by using the connection terminal 51 as a crimp terminal with the vinyl cover 52 attached, the connection portion can be reliably insulated.

  In FIG. 4, only one pin insertion hole 13 is shown, but the other pin insertion hole 12 is also provided with the same contact 14, terminal 16, lead wire 50, and the like as described above. 4 shows the socket 10 of FIG. 1, the same structure as that of FIG. 4 is adopted for the socket 20 of FIG.

  The present invention is not limited to the above-described embodiments, and various embodiments can be adopted besides these. For example, regarding the relationship between the distance X between the pin insertion holes of the LED lamp socket and the distance Y between the electrode pins of the fluorescent lamp, in the above embodiment, X> Y in the case of the AC power supply method (FIG. 1), and DC power supply. In the case of the system (FIG. 2), X <Y may be used. However, according to the voltage specification, in contrast to the above, X <Y may be used in the AC power supply system and X> Y in the DC power supply system. .

  In the above embodiment, the electrode pin interval Y of the fluorescent lamp 300 is 12.7 mm, the pin insertion hole interval X of the socket 10 is 14.7 mm, and the pin insertion hole interval X of the socket 20 is 10.7 mm. However, these dimensions are examples, and it goes without saying that other dimension values may be adopted.

  In FIG. 4, an example in which the lead wire 50 provided with the connection terminal 51 for power supply is attached to the socket 10 is given. Instead, a connection terminal (not shown) for power supply is provided on the socket 10 itself. A power cable connector may be connected to this. The same applies to the socket 20.

  Further, the shape and structure of the socket are not limited to those shown in the drawings, and the present invention can be applied to sockets having other shapes and structures.
