Description

  The present invention relates to a straight tube type light source built-in lamp having an appearance similar to that of a straight tube type fluorescent lamp and having a substrate on which a light emitting diode or the like is mounted.

  Conventionally, as a long straight tube fluorescent lamp suitable for facility lighting or the like, a 110 W type and a 86 W type (only for high frequency lighting) having a different tube diameter and tube length are commercially available. However, they are not compatible and the shape of the base part is also different. Hereinafter, this point will be described.

  FIGS. 7A to 7G are diagrams showing the connection relationship between a 110 W fluorescent lamp and a socket. Here, (a) is a side view of one socket, (b) is a front view showing a metal receiving part of the socket, (c) is a front view of a fluorescent lamp showing a base part, and (d) is a side view of the lamp. (E) is a rear view showing the cap portion of the lamp, (f) is a front view showing the receiving portion of the other socket, and (g) is a side view of the socket. One socket and the fluorescent lamp are connected in a state where the paper surface between (b) and (c) is folded down, and the other socket and the fluorescent lamp are paper surface between (e) and (f). Are connected in a state where the valley is folded.

  As shown in (c) and (e), the base part 13 of the 110W type fluorescent lamp 100 comprises a pair of electrodes 13a and a fitting convex frame 13b surrounding the electrodes 13a. The combined convex frame 13b has a smooth elliptical shape with no irregularities around it. In the socket 200, as shown in (b) and (f), a fitting concave frame 21b corresponding to the fitting convex frame 13b is formed in the metal receiving part 21, and a pair of electrodes 21a is provided on the inside thereof. It has been.

  On the other hand, FIGS. 8A to 8G are diagrams showing the connection relationship between the 86W fluorescent lamp and the socket. Here, (a) is a side view of one socket, (b) is a front view showing a metal receiving part of the socket, (c) is a front view of a fluorescent lamp showing a base part, and (d) is a side view of the lamp. (E) is a rear view showing the cap portion of the lamp, (f) is a front view showing the receiving portion of the other socket, and (g) is a side view of the socket. One socket and the fluorescent lamp are connected in a state where the valley is folded between (b) and (c), and the other socket and the fluorescent lamp are valley-folded between (e) and (f) Connected in state.

  As shown in (c) and (e), the base part 13 of the 86W type fluorescent lamp is provided with projections 13x at two opposing positions of the fitting convex frame 13b, and the socket 200 is also composed of (b) and (f).

Japanese Patent No. 4261808

  By the way, in recent years, due to an increase in energy saving, a low power consumption type using a light emitting diode or the like is increasingly used instead of a conventional lighting fixture. A straight tube fluorescent lamp is no exception, and a straight tube light source interior lamp having an appearance similar to this and having a substrate mounted with a light emitting diode mounted therein has been developed and marketed.

  Such straight tube light source interior lamps are provided with bases at both ends like fluorescent lamps. However, since the light emission principle is different from fluorescent lamps, DC power corresponding to the light source is supplied through the base part. Alternatively, it is necessary to supply an AC power source suitable for the power circuit accommodated in the lamp, and it is also necessary to ground for safety.

  Therefore, the present invention has an object to provide a straight tube type light source interior lamp capable of using an existing power supply socket for a fluorescent lamp as it is when replacing a conventional fluorescent lamp with a straight tube type LED lamp or the like. And

  Furthermore, in a straight tube type light source built-in lamp in which a base part to be connected to the ground side socket and the power supply side socket is provided at both ends, a straight tube type light source built-in lamp that does not cause an erroneous connection between the base part and the socket is provided. For the purpose.

  Further, when the conventional fluorescent lamp is replaced with a straight tube type LED lamp or the like, the base part of the existing fluorescent lamp cannot be connected, and the straight tube type which can connect only the straight tube type light source interior lamp of the present invention can be connected. An object of the present invention is to provide a power supply socket for a light source interior lamp.

  A straight tube light source interior lamp according to the present invention is a lamp in which a substrate on which a light emitting element is mounted is accommodated in a tube provided with a translucent cover, and a base part is provided at both ends, each of the base part. Has an electrode and a fitting convex frame surrounding the electrode, and a part of the fitting convex frame is divided to form a matching concave portion.

  One of the base parts is provided with a grounding electrode, the other is provided with a power feeding electrode, and the position of the mating concave part formed in the one base part and the joint concave part formed in the other base part The position should be different.

  One of the cap parts includes a grounding electrode, the other includes a power feeding electrode, and the number of mating recesses formed in the one cap part and the number of mating recesses formed in the other cap part. The number may be different.

  The lamp socket according to the present invention includes a pair of metal receiving portions that are fitted and connected to the base portions provided at both ends of the lamp in order to supply power to the straight tube light source interior lamp. Rib-shaped protrusions corresponding to the mating recesses formed on the mating convex frame are formed on the metal receiving part side.

  Here, one socket includes a receiving part into which the fitting projection frame of the one base part is inserted, and the receiving part has a rib-like protrusion corresponding to the mating recess of the one base part. Formed and elastically biased toward the other socket so as to be retractable, and the other socket includes a receiving portion into which the fitting projection frame of the other base portion is inserted, The receiving part may be formed with rib-shaped protrusions corresponding to the mating recesses of the other base part.

  The illumination device according to the present invention is configured by combining the straight tube light source interior lamp and the straight tube light source interior lamp socket.

  According to the straight tube-type light source built-in lamp of the present invention, since no special projection or the like is provided on the fitting convex frame of the base of the lamp, the dimension and shape of the lamp are designed to be the same as the conventional fluorescent lamp, And if it forms in the dimension shape which can be inserted in the recessed part formed in the metal receiving part of the conventional power supply socket, it can be used as it is, without replacing the socket for conventional fluorescent lamps. Therefore, the modification for using the straight tube type LED lamp in the conventional lighting fixture is simplified, and the resources can be effectively used. In the modification, it is necessary to replace the power supply circuit or change the wiring. However, since the socket can be used as it is, the electrical work at the time of renovation can be facilitated and the cost can be reduced.

  Also, the base portions provided at both ends of the straight tube type light source interior lamp have the structure of claim 2 or 3, and the socket structure corresponding to them is formed in a structure corresponding to one base portion and the other base portion. By using it in combination with it, it is possible to prevent erroneous connection to the grounding socket and the power feeding socket. In particular, according to the configuration of the second aspect, since the positions of the mating recesses provided in the base portions at both ends are different from each other, when connecting the straight tube light source interior lamp to the power supply socket, The connection is not reversed. The structure of the cap part according to claim 2 or 3 may be applied to either a direct current feeding type with polarity or a non-polar alternating current feeding type of a straight tube light source interior lamp. If the structure of one of the cap parts is specified as a DC power supply type and the structure of the other base part is specified as an AC power supply type, the DC power supply type is mistakenly connected to the AC power supply type or vice versa. This can be prevented beforehand.

  According to the power supply socket for the straight tube type light source interior lamp of claims 4 and 5, the fitting convex frame of the straight tube type light source interior lamp according to claim 1 is formed on the metal receiving part side of the power supply socket. Rib-shaped protrusions corresponding to the mating recesses are provided. In this case, since the rib-like protrusion is fitted into the mating recess, the base portion can be connected to the receiving portion. However, since the conventional fluorescent lamp does not have such an alignment recess, the connection is rejected by the rib-shaped protrusion provided on the metal receiving portion. Therefore, the existing fluorescent lamp is not connected by mistake.

According to the lighting device of the present invention described in claim 6, the conventional fluorescent lamp cannot be connected to the power supply socket, and only the straight tube light source interior lamp of the present invention can be connected.
Here, the illumination device of the present invention is configured by combining any of the straight tube type light source interior lamps described in claims 1 to 3 with any of the lamp sockets described in claims 4 and 5. There is an effect corresponding to each.

A part of the substrate is omitted.
3A and 3B are drawings showing the external appearance of the socket, wherein FIG. 3A is a perspective view of the grounding socket, and FIG. 3B is a perspective view of the power supply socket.

The lamp 1 has a basic structure in which a substrate 11 on which a light emitting element is mounted is accommodated in a tube provided with a translucent cover 12 and a base portion 13 is provided at both ends. The light-emitting element 11a is preferably a high-intensity white light-emitting diode, but is not limited thereto, and other types of light-emitting elements may be adopted.
The lamp 1 is formed by joining a cylindrical translucent cover 12 having a substantially semicircular cross-section to a cylindrical metal body 14 having a substantially semicircular cross-section so as to face each other, and as a whole is a straight tube like a fluorescent lamp. It has become the appearance.

  The substrate 11 is fixed to the metal body 14 such that the light emitting element 11a faces the translucent cover 12 side. The translucent cover 12 has a lens pattern 12a engraved in a streak shape in the longitudinal direction so that when the lamp 1 is disposed at a predetermined height, the light distribution characteristic illuminates the floor surface well. The translucent cover 12 may be a transparent resin or a milky white resin, but the amount of the diffusing agent contained in the resin is determined in consideration of the light distribution characteristics.

  The light emitting element 11a is generally DC driven, but the lamp 1 itself can have a configuration corresponding to DC power supply or a configuration compatible with AC power supply. In the former case, a DC power supply (not shown) required for the main body of the lighting fixture (not shown) may be provided, and in the latter case, a similar DC power supply (not shown) is built in the lamp 1. Just do it. In this case, the DC power supply device may be disposed behind the substrate 11 or the like.

Hereinafter, the configuration corresponding to the direct current power supply will be described in detail with respect to the configuration of the cap portion 13 of the lamp 1 and the configuration of the socket receiving portion 21.
The base part 13 is fixed to both ends of the metal body 14. As shown in FIGS. 2A and 2B, one of the base parts 13 is a grounding base part 13A provided with a grounding electrode, and the other is a power supply base part 13B provided with a DC power supply electrode. is there. Each base part 13 has a pair of electrodes 13a and an insulating convex frame member 13d formed with a fitting convex frame 13b surrounding them.
The fitting convex frame 13 b has an elliptical shape, and the major axis of the ellipse coincides with the width direction of the substrate 11. Further, a part of the fitting convex frame 13b is divided, and the divided part forms a combined concave part 13c.

In the grounding cap 13A, the alignment recess 13c is formed on the upper side (the lamp ceiling side) of the fitting convex frame 13b, that is, on the metal main body 14 side. On the other hand, in the power supply cap 13B, the mating recess 13c is formed on the lower side (the lamp floor side) of the fitting convex frame 13b, that is, on the side of the translucent cover 12 side.
That is, the alignment recess 13c formed in the grounding cap portion 13A and the alignment recess 13c formed in the power supply cap portion 13B are different in the upper and lower positions, but different configurations in the upper and lower positions are as follows. It is only an example, and the point is that the positions of both may be different. In this example, the mating concave portion 13c is formed in a slit shape by dividing a part of the fitting convex frame 13b. However, the matching concave portion 13c is formed in a groove shape by bending inward without dividing the same portion. Also good.

Corresponding to the cap portion 13 of the lamp 1, the socket 2 is also classified into two types, that is, grounding and power feeding. In the following, these are referred to as a grounding socket 2A and a power feeding socket 2B, respectively. The power supply socket 2 </ b> B is used as a pair with respect to the lamp 1.
That is, they are fixed and installed on the main body of the lighting fixture or the ceiling surface of the building with the receiving portion 21 facing each other at a distance suitable for the tube length of the lamp 1.

  As shown in FIG. 3A, the grounding socket 2 </ b> A includes a leg portion 22 fixed to the lighting fixture body or the ceiling surface of the building, and a metal receiving portion 21 adapted to the grounding base portion 13 </ b> A of the lamp 1. With. The receiving part 21 includes a pair of electrodes 21a and an insulating concave frame member 21d formed with a fitting concave frame 21b into which the fitting convex frame 13b of the grounding base part 13A is inserted. The concave frame member 21d protrudes from the leg portion 22 so as to be retractable, and receives a biasing force toward the other power feeding socket by an elastic body (not shown) such as a spring. The fitting concave frame 21b has an elliptical shape corresponding to the fitting convex frame 13b.

  On the inner peripheral surface of the fitting concave frame 21b, rib-like protrusions 21c are formed corresponding to the mating concave portions 13c formed on the fitting convex frame 13b of the grounding cap part 13A. Since the mating recess 13c of the ground-side base part 13A is provided on the upper side of the fitting convex frame 13b, this rib-shaped protrusion 21c is also provided on the upper side of the fitting concave frame 21b.

  An electrode fixing portion 21e (see FIG. 1B) is formed so as to protrude from the inner central portion of the fitting concave frame 21b. In this example, the rib-shaped protrusion 21c is formed so as to connect the fitting recessed frame 21b and the electrode fixing portion 21e. However, such a connection structure is not essential, and the shape of the mating recess 13c is used. It only needs to be compatible.

  Each of the pair of electrodes 21a provided on the electrode fixing portion 21e has a plate shape, and is provided side by side on a plane including the elliptical long axis of the fitting concave frame 21b. Further, these electrodes 21a can be expanded or contracted on the surface thereof, and are urged by an elastic body (not shown) in a direction to expand the distance. Therefore, when the grounding base portion 13A is fitted into the receiving portion 21 of the grounding socket 2A, each outer end surface of the electrode 21a is made of an elastic body with respect to each surface of the base portion-side electrode 13a facing each other. The electrical connection is ensured by pressing with the urging force.

  One power feeding socket 2B has basically the same structure as the grounding socket 2A, but as shown in FIG. 3B, the concave frame member 21d constituting the metal receiving portion 21 is The rib-like protrusion 21c formed integrally with the leg 22 so as not to move and formed on the fitting concave frame 21b is an alignment concave formed on the fitting convex frame 13b of the feeding base 13B. Corresponding to 13c, it is provided on the lower side of the fitting concave frame 21b.

Next, as an example different from the above, the configuration of a lamp and socket compatible with AC power supply will be described. Note that a detailed description of points common to the configuration corresponding to DC power supply is omitted.
FIG. 4 is a view showing a connection relationship between a straight tube type light source interior lamp and a socket. Here, (a) is a side view of a socket for grounding, (b) is a front view showing a metal receiving part of the socket, (c) is a front view of a straight tube type light source interior lamp showing a base part, (d). Is a side view of the lamp, (e) is a rear view showing a cap portion of the lamp, (f) is a front view showing a receiving portion of a power supply socket, and (g) is a side view of the socket. . Here, the grounding socket and the straight tube light source interior lamp are connected in a state where the valley between (b) and (c) is folded. The straight tube light source interior lamp and the power supply socket are connected in a state where the gap between (e) and (f) is valley-folded, similar to the lamp described above.
FIG. 5 is a perspective view of a straight tube light source interior lamp, and FIG. 6 is a perspective view of a power supply socket.

  The lamp 1 compatible with AC power supply has a built-in DC power supply circuit (not shown) for supplying power to the light emitting element 11a, and has a grounding cap 13A and an AC power supply at each end of the lamp 1. And a base part 13B.

  The grounding cap 13A may be the same as that of the lamp 1 compatible with DC power supply, but the power supply cap 13B may be different from that of the lamp 1 compatible with DC power supply. Even when drive-type and AC-drive-type lighting fixtures are mixed, it is possible to prevent erroneous installation at the enforcement site, which is extremely desirable.

  In place of the configuration shown in FIGS. 1 to 4, the number of matching recesses 13c formed in the grounding cap 13A and the number of matching recesses 13c formed in the power feeding cap 13B are different. You may prepare. In the example of FIGS. 5 and 6, the grounding cap portion 13 </ b> A is formed with an alignment concave portion 13 c on the upper side (ceiling side) of the fitting convex frame 13 b, as in the case of the lamp 1 compatible with DC power feeding. However, the power supply cap 13B has two alignment recesses 13c, one of which is formed on the upper side (ceiling side) of the fitting convex frame 13b, that is, the side of the metal main body 14, and the other is fitted. It is formed on the lower side (floor side) of the convex frame 13b, that is, the side on the side of the translucent cover 12, and these alignment concave portions 13c are provided at opposing positions on the fitting convex frame 13b.

  The grounding socket 2A is common to the configuration corresponding to the DC power supply, but the power supply socket 2B corresponds to each of the two alignment recesses 13c formed in the fitting convex frame 13b of the power supply base part 13B. Two rib-shaped protrusions 21c are formed.

  In the two types of straight tube light source built-in lamps configured as described above, no special protrusions are provided on the fitting convex frame formed on the base part, so that they can be mounted on conventional fluorescent lamp sockets as they are. it can. Therefore, the modification for using these lamps in the conventional lighting apparatus is simplified, and the resources can be effectively used. Further, when replacing the luminaire, it is necessary to replace the power supply circuit or change the wiring. However, since the socket can be used as it is, the electrical work at the time of renovation can be facilitated and the cost can be reduced.

  In addition, the illuminating device including the straight tube type light source built-in lamp of the two types configured as described above is fitted to the fitting recess of the lamp cap, both of which are a grounding socket and a power supply socket. Since the position and number of rib-shaped protrusions are different, it is possible to prevent the lamp from being mounted upside down or from being mounted with the grounding side and the power feeding side reversed.

  Moreover, one combination type of the lighting device which combines the straight tube type light source built-in lamp of the two types of configurations configured as described above and a pair of sockets corresponding thereto is a DC power supply type lamp and the other combination If the type is used separately as an AC power supply type lamp, both the DC power supply type lamp, the grounding base part corresponding to the AC power supply type lamp, and the power supply base part are used for power supply of the AC power supply type lamp and the DC power supply type lamp. Since it is not inserted into the socket, it is possible to prevent damage to the lamp itself and the lighting fixture due to incorrect mounting of the lamp.

  In addition, since the base of a conventional fluorescent lamp does not fit into either a lamp socket that supports DC power supply or a lamp socket that supports AC power supply, the lamp itself may be damaged due to incorrect mounting of the fluorescent lamp, Damage to lighting equipment can also be prevented

  In the above description, in a lamp that supports direct current power supply, the position of the mating recess formed in one base part is different from the position of the mating concave part formed in the other base part, so that AC power supply is supported. In the lamp, the number of mating recesses formed in one base part is different from the number of mating recesses formed in the other base part. However, in a lamp that supports the reverse configuration, that is, for direct current power supply, the number of mating recesses formed on one base and the number of mating recesses formed on the other base are different, so that AC power supply is supported. In the lamp, it is needless to say that the position of the mating recess formed in one base part and the position of the mating recess formed in the other base part may be different.
