Description

  The present invention relates to a lighting fixture using LEDs.

  In recent years, with the trend toward higher efficiency and higher output of LEDs, it has become possible to use LEDs for base illumination. The use of LEDs as the light source can significantly reduce the energy consumption and extend the life of fluorescent lamp fixtures. Therefore, lighting fixtures using LEDs are attracting attention as alternatives to fluorescent lamp fixtures.

  However, since the light emission mechanisms of fluorescent lamps and LEDs are different, it is not possible to simply remove an existing fluorescent tube and replace it with a fluorescent lamp type LED tube. To make an LED, generally remove the fluorescent light ballast from the lamp in use and install a dedicated power supply (AC / DC converter) according to the type of LED tube, or install a new power supply with a dedicated power supply. It is necessary to replace the lamp with the lamp. However, each work requires a switching work by a specialist or the like, and requires a construction period and cost for introduction. In general, a different dedicated power source is required for each type of LED tube. Therefore, even if an LED is used, if the life of the LED is reduced, the LED tube needs to be replaced with a dedicated power source. In addition, in the case of a tenant or the like, the original state must be restored when leaving the tenant, so the ballast must be reattached or returned to the original lamp. This is one of the barriers when promoting the use of LEDs.

  In addition, it has also been proposed to incorporate a power supply in the LED tube instead of externally attaching the power supply (Patent Document 1). Such a built-in type has the advantage that it is not necessary to replace the ballast with a power supply. On the other hand, the built-in power supply increases the weight of the LED tube and increases the risk of falling. It has also been pointed out that the built-in type has a shorter life because the temperature of the LED tube is higher than the normal one.

  In view of such a situation, the present invention intends to provide a lighting fixture that can also use an existing lamp when the lighting fixture is made into an LED.

  In the luminaire according to the predetermined embodiment of the present invention, the power supply unit and the LED tube are arranged outside the lamp. The power supply unit includes a power supply for the LED and a socket connected to the power supply. The LED tube includes a base connected to a socket and an LED substrate on which one or more LED elements are arranged.

  In addition, a power supply unit according to another embodiment of the present invention includes a power supply for LEDs and a socket connected to the power supply and configured to be connectable to a base of the LED tube, outside the lamp and the LED tube. Be placed.

  According to the predetermined aspect of the present invention, there is provided a lighting fixture that can use an existing lamp when making the lighting fixture into an LED. At this time, for example, it is not necessary to remove the ballast, and the installation of the LED lighting fixture including the power supply becomes simpler than before. Can be done.

However, any structure can be applied as long as the power supply unit 20 can be fixed.

  The auxiliary plate 134 is connected in a direction substantially orthogonal to the upright plate 133. That is, the auxiliary plate 134 is in a position substantially parallel to the substrate 132. A power socket 136 is installed near the center of the auxiliary plate 134, and AC power is drawn from the lamp 10 through the cord 137. Therefore, the substrate 132 is preferably provided with a hole 138 through which the cord 137 passes. An insertion port is provided on the upper portion of the power socket 136, and when the power supply unit 20 is installed in the lamp 10, a plug (not shown) provided in the power supply unit 20 is configured to be inserted into the insertion port. .

  FIG. 5 is a diagram showing an example of a schematic configuration of the LED tube support fitting 14 in the present embodiment. As shown in the figure, the LED tube support bracket 14 is a bracket in which the base 142 and the upright plate 143 are configured in an approximately L shape when viewed from the side. The LED tube support bracket 14 has a configuration in which the auxiliary plate 134, the power socket 136, and the cord 137 are removed from the power supply support bracket 13. That is, the substrate 142 is configured to interfere with the concave portion 112 in the vicinity of the other end side in the longitudinal direction of the main body 11 to be hooked. Various dimensions of the socket 19 are conceivable, but by appropriately adjusting the size and shape of the substrate 142, the substrate 142 can be engaged with the recess 112 regardless of the shape of the recess 112. Improves versatility.

  The upright plate 143 is connected in a direction substantially orthogonal to the substrate 142 via the notch 141. The LED tube support bracket 14 includes a lock mechanism 145 for fixing the support unit 30. In this embodiment, a pair of locking holes 1451 and 1451 protrude from the upright plate 143 in the vertical direction. 1452. The ear plates 1452 and 1452 extend in a direction substantially orthogonal to both the standing plate 143 and the substrate 142, and the locking holes 1451 and 1451 are holes in a direction parallel to both the substrate 142 and the standing plate 143. However, any structure can be applied as long as the support unit 30 can be fixed.

  FIG. 6 is a diagram illustrating an example of a schematic configuration of the cover presser 15 in the present embodiment. As shown in the figure, the cover presser 15 includes an opening 151 from the center periphery toward one end. The opening 151 includes a positioning taper 152 that increases from the center toward the outside. The tip 153 opposite to the opening 151 is bent toward the lamp 10 side.

  The arrangement method of the cover retainer 15 is as follows. After the power supply support fitting 13 is hooked on the concave portion 111 of the main body 11 and the cover 12 is covered, the cover presser 15 is slid in the direction of the arrow X in FIG. 4 so that the taper peripheral portions 154 and 154 of the cover presser 15 are The power supply support fitting 13 is fitted into the notches 131 and 131. The cover 12 is fixed by the elastic force generated in the cover presser 15 by the action of the fitted portion and the tip 153. The cover retainer 15 is installed not only on the power supply support bracket 13 but also on the LED tube support bracket 14 side, and the cover 12 is similarly fixed. As described above, the cover 12 is conventionally fixed to the main body 11 with the screw 18. In this embodiment, the cover 12 is fixed to the main body 11 with the cover press 15 instead of the screw 18. However, since the cover presser 15 is for fixing the cover 12 to the main body 11 while avoiding interference with the power supply unit 20 or the support unit 30, the power supply unit 20 or the support unit is determined depending on the position or shape of the screw 18. In the case of not interfering with 30 or the like, it is preferable to fix the cover 12 to the main body 11 by using the screw 18 together as in the conventional case.

  In addition, the ballast which is not illustrated is generally arrange | positioned in the space formed by the main body 11 and the cover 12 conventionally. In this embodiment, when the conventional fluorescent tube lamp 17 is used as the LED tube lamp 10, it is not necessary to replace the ballast with an LED power source.

  Next, a mechanism for attaching the power supply unit 20 and the support unit 30 to the lamp 10 will be described.

  FIG. 7 is a diagram illustrating an example of a schematic configuration of the power supply unit 20 in the present embodiment. As shown in the figure, the power supply unit 20 includes a socket 21 for connecting the LED tube 40 and a receiving port 22 cut out in a concave shape along the shape of the LED tube 40 on one surface 201 side. Further, claws 23 and 23 are provided to be fitted to the cap 41 of the LED tube 40 from the side surfaces 203 and 203 in the vicinity of the receiving port 22 toward the surface 201.

  The power supply unit 20 is fixed to the power supply support fitting 13 by a claw provided on a leaf spring (not shown) engaging the lock mechanism 135. An AC / DC converter (power source) (not shown) that rectifies from alternating current to direct current is provided inside the power supply unit 20. When the power supply unit 20 is fixed to the power supply support bracket 13, AC power is supplied to the AC / DC converter via the power socket 136. The AC / DC converter supplies a direct current power source for the LED to the socket 21.

  FIG. 8 is a diagram illustrating an example of a schematic configuration of the support unit 30 in the present embodiment. As shown in the figure, the support unit 30 has the same configuration as that of the power supply unit 20 except that the configuration related to the power supply such as an AC / DC converter and a power supply socket is not incorporated. That is, the support unit 30 includes a receiving port 32 cut out in a concave shape along the shape of the LED tube 40 on the one surface 301 side. Further, claws 33, 33 that are fitted to the cap of the LED tube 40 are provided from the side surfaces 303, 303 near the receiving port 32 toward the surface 301. On the side surfaces 303 and 303 in the vicinity of the other surface 302, unlock buttons 34 and 34 connected to a pair of leaf springs 36 and 36 having claws 37 and 37 at the tips penetrate from the inside of the case 35 to the outside. . Note that the support unit 30 does not necessarily require electrical wiring.

  FIG. 10A is a diagram showing a mechanism for fixing the support unit 30 in this embodiment to the LED tube support fitting 14. As shown in the figure, when the leaf springs 36, 36 are slid in the direction of arrow Y when the support unit 30 is attached to the lamp 10, the leaf springs 36, 36 and the lock mechanisms 145, 145 cause the leaf springs. The claws 37, 37 provided near the tips of 36, 36 are engaged with the locking holes 1451, 1451, whereby the support unit 30 is fixed to the lamp 10.

  FIG. 10B is a diagram showing a mechanism for removing the support unit 30 in the present embodiment from the LED tube support fitting 14. As shown in the figure, when the lock mechanism 145 is unlocked, when the lock release button 34 is pushed in the direction W, the engagement between the claw 37 and the lock hole 1451 is released. If the support unit 30 is moved downward in this state, the support unit 30 can be removed from the LED tube support fitting 14. The mechanism for fixing or releasing the power supply unit 20 with respect to the power supply support fitting 13 is the same as that shown in FIG.

  FIG. 9 is a schematic cross-sectional view in the longitudinal direction when the power supply unit 20, the support unit 30, and the LED tube 40 in the present embodiment are installed in the lamp 10. The LED tube 40 includes a magnet for fixing the LED tube 40 to the cover 12, and is fixed to the cover 12 by the magnetic force of the magnet. In the example shown in FIG. 9, a rubber magnet (not shown) is attached or embedded in the heat sink 43 provided on the back surface of the LED unit 47 including one or more LED elements 45. Moreover, you may make it provide the magnet 42 inside the LED part 47 as shown in FIGS. Thus, the LED tube 40 is fixed to the lamp 10 by the magnetic force of the magnet provided in the LED tube 40.

  In addition, the caps 41, 41 at both ends of the LED tube 40 are configured to be mechanically supported by the receiving port 22 of the power supply unit 20 and the receiving port 32 of the support unit 30. Here, the power supply unit 20 is fixed to the lamp 10 by a claw provided on a leaf spring (not shown) provided in the power supply unit 20 being engaged with the lock mechanism 135 of the power supply support fitting 13. Further, the support unit 30 is fixed to the lamp 10 by engaging a claw 37 of a leaf spring 36 provided in the support unit 30 with a lock mechanism 145 of the LED tube support fitting 14.

  Thus, the power supply unit 20, the support unit 30, and the LED tube 40 each have a mechanism that is individually fixed to the lamp 10, and the LED tube 40 is operated by the action of the power supply unit 20 and the support unit 30. Is fixed to the lamp 10. In the present embodiment, the LED tube 40 is prevented from falling by various means.

  The power supply unit 20 is provided with a recess 28 on the surface facing the lamp 10, and the cover presser 15 is configured to fit into the recess 28 when the power supply unit 20 is installed in the lamp 10. As a result, interference between the power supply unit 20 and the cover presser 15 is prevented, and when the power supply unit 20 is installed, the cover presser 15 itself is provided when the bottom surface of the recess 28 is adjusted so as to partially contact the cover presser 15. Can be pressed toward the cover 12. Similarly, the support unit 30 is provided with a recess 38 on the surface facing the lamp 10, and acts similarly to the recess 28 of the power supply unit 20.

  Although not shown, the electrical connection is as follows. First, in the lamp 10, AC power is drawn out to the power socket 136 of the power support bracket 13. In the power supply unit 20, AC power is supplied to the AC / DC converter via a plug inserted into the power socket 136, and LED DC power is supplied to the socket 21. To do. Then, a direct current is supplied to the LED substrate 44 through the base 41 inserted into the socket 21, and each LED element 45 emits light. In the example shown in FIG. 9, the base 41 at the other end of the LED tube 40 is connected to the extension cable 60 in the support unit 30. More specifically, the base 41 of the LED tube 40 is connected to the first connector 61 of the extension cable 60, and the second connector 62 (not shown) is connected to another LED tube 40 in the support unit 30. In this case, a plurality of LED tubes 40 are turned on by one power supply unit 20.

  FIG. 11 is a diagram illustrating an example of the LED tube 40 in the present embodiment. 12 is a sectional view taken along line XII-XII in FIG. 13 is a sectional view taken along line XIII-XIII in FIG. As shown in FIGS. 11 to 13, the LED tube 40 includes a magnet 42, a heat sink 43, an LED substrate 44, an LED element 45, and a light diffusion cover 46. The light emitted from the LED element 45 is diffused through the light diffusion portion 463 of the light diffusion cover 46.

  The heat sink 43 is bent in the substantially vertical direction in the vicinity of both ends of the cross section, and then bent outward in the substantially horizontal direction, so that both ends are folded. The folds formed at both ends of the heat sink 43 are configured to engage with L-shaped heat sink joints 461 formed at both ends of the cross section of the light diffusion cover 46. An LED substrate 44 on which one or more LED elements 45 are arranged is disposed on one surface of the heat sink 43 (the surface facing downward when the LED tube 40 is installed on the ceiling), and extends from the vicinity of both ends of the cross section of the light diffusion cover 46. Then, the LED substrate 44 is brought into close contact with the one surface of the heat sink 43 by the substrate pressing portion 462 protruding like a bowl in a direction facing the one surface of the heat sink 43. Further, the LED tube 40 includes a magnet 42 inside or outside, and the heat sink 43 is brought into close contact with the cover 12 of the lamp 10 or a heat sink (not shown) with the magnet 42. By providing such a configuration, the heat of the LED element 45 is dissipated. In this way, by using an existing lamp to dissipate heat, the heat sink material on the LED light source side can be reduced and the cost can be reduced. In the embodiment shown in FIG. 9, an example is shown in which a rubber magnet (not shown) is attached to one surface of the heat sink 43 (the surface facing the cover 12). In the embodiment shown in FIGS. 11 to 13, an example is shown in which magnets 42 are attached in the vicinity of both ends of the LED substrate 44 in the longitudinal direction.

  Conventionally, there is a device in which the LED substrate is simply inserted into the groove of the heat sink. However, such a structure requires a clearance for manufacturing, and the air portion of the air gap increases the thermal resistance. On the other hand, in this embodiment, in order to improve the adhesion between the LED substrate 44 and the heat sink 43, the light diffusion cover 46 is configured to press the LED substrate 44 against the heat sink 43. Resistance can be suppressed. Further, since the light diffusion cover 46 and the heat sink 43 are fitted together, strength against external force can be expected.

  FIG. 14 is a diagram illustrating an example of a connection mechanism between the power supply unit 20 and the LED tube 40 in the present embodiment. As shown in the figure, the LED tube 40 is provided with a base 41 having a substantially U-shaped cross section in a direction orthogonal to the longitudinal direction at both ends thereof. The base 41 includes a notch portion 417 in which a back surface (a surface facing the lamp 10) 48 is notched from the end portion 411 to the vicinity thereof. Thereby, when the LED tube 40 is installed in the lamp 10, a gap is formed between the lamp 10 and the notch 417 of the base 41. Further, the end portion 411 of the base 41 has a left end portion 412 and a right end portion 412 protruding in the longitudinal direction, and a notch portion in which the vicinity of the center is notched in a substantially vertical direction with respect to the back surface 48 of the LED tube 40. 413 is formed. A pair of LED side electrodes 414 is disposed in the notch 413. The shape of the electrode 414 is a so-called plug shape of an electrical outlet. That is, it has a shape in which two long thin plates are arranged substantially in parallel. Further, a notch portion 415 that is notched in a direction substantially perpendicular to the surface 48 is formed on the side surface in the vicinity of the end portion 411 of the base 41, and as a result, the surface 48 side of the left end portion 412 and the right end portion 412. Protrusions 416 and 416 that can engage the claws 23 of the power supply unit 20 are formed in the vicinity of the ends.

  Further, the socket 21 of the power supply unit 20 includes a pair of power supply side electrodes 213 having a shape capable of accommodating the electrode 414. The power supply side electrode 213 has a shape opened from the surface 211 facing the LED tube 40 to the surface 212 facing the lamp 10. Thereby, when the LED tube 40 is moved horizontally in the arrow U direction, the socket 21 and the electrode 414 are fitted from the surface 211 side. At this time, the claws 23 and 23 are fitted to the protrusions 416 and 416. In this state, when the LED tube 40 is moved vertically in the direction of the arrow V, or when the power supply unit 20 is moved vertically in the direction opposite to the arrow V, the electrode 414 can be extracted from the socket 212 from the surface 212 side. it can. At this time, the claws 23 and 23 are slid along the notch 415, and the fitting is released. By adopting such a socket shape, the horizontal connection movement for attaching the LED tube 40 and the vertical connection movement for replacing the power supply unit 20 and the like after the LED tube 40 is installed depend on both directions. Connection or removal movement is possible.

  FIG. 15 is a diagram showing an outline of attachment and detachment of the power supply unit 20 and the LED tube 40 in the present embodiment. As shown in FIG. 5A, when attaching the lighting fixture in this embodiment, first, the power supply unit 20 is fixed to the lamp 10, and then the LED tube 40 is slid in the longitudinal direction in the horizontal direction. The LED tube 40 is attached to the power supply unit 20 by connection movement. On the other hand, when removing the lighting fixture, as shown in FIG. 2B, first, the power supply unit 20 is removed from the lamp 10 by a vertical removal movement, and then the LED tube 40 is removed from the lamp 10.

  FIG. 16 is a diagram illustrating an example of the connection connector 50 and the extension cable 60 in the present embodiment. The connection connector 50 is used when a plurality of LED tubes 40 are connected adjacently in series. The connection connector 50 is shaped to fit into the notch 413 of the base 41, and the LED side electrode 414 of one LED tube 40 and the LED side electrode 414 of another LED tube 40 are connected to the connection connector 50. The connector electrode 51 is used for connection. When the two LED tubes 40 are connected by the connection connector 50, the movement of the base 41 of the connected portion in the horizontal direction or the vertical direction orthogonal to the longitudinal direction of the LED tube 40 is caused by the action of the connection connector 50. Is limited. Further, when the two LED tubes 40 are arranged in the lamp 10 in a connected state, a gap is formed between the connected portions and the lamp 10.

  Further, in the extension cable 60, the first connector 61 is accommodated in the one support unit 30, and the electrode provided in the first connector 61 is connected to the LED side electrode 414 of the LED tube 40. A second connector 62 connected to the first connector 61 via a cable is housed in another support unit 30, and an electrode provided on the second connector 62 is an LED of another LED tube 40. Connected to the side electrode 414. The first connector 61 and the second connector 62 have a shape that fits into the notch 413 of the base 41.

  17 to 20 are diagrams showing a procedure for attaching the two LED tubes 40, the power supply unit 20, and the support unit 30 to the lamp 10 in the present embodiment. The same procedure may be performed when one or a plurality of LED tubes 40 are attached.

  First, as shown in FIG. 7, the power supply unit 20 is fixed to the lamp 10 using the lock mechanism 135 of the power supply support fitting 13. Next, as shown in FIG. 17, the first LED tube 40 is slid in the longitudinal direction, and the LED side electrode 414 of the base 41 is inserted into the socket 21 of the power supply unit 20. Next, as shown in FIG. 18, the connection connector 50 is connected to the LED side electrode of the first LED tube 40 414, and the second LED tube 40 is further slid in the longitudinal direction, so that the LED of the base 41 The side electrode 414 is inserted into the connection connector 50. Note that there may be a cover mounting screw 18 or a fall prevention fitting near the center of the lamp 10, but in this embodiment, based on the shape of the notch 417 of the base 41 and the connecting connector 50, Since a gap is formed between the connected portion and the lamp 10 so that the screws 18 and the like do not interfere with each other, it is not necessary to avoid the screws 18 and the like when installing the LED tube 40. Finally, as shown in FIG. 19, the support unit 30 is fixed to the lamp 10 using the lock mechanism 145 of the LED tube support bracket 14.

  Thus, as shown in FIG. 20, the LED tube 40 is fixed to the lamp 10 by the magnetic force of the magnet 42. In addition, the LED tube 40 is physically fixed to the lamp 10 by the action of the receiving port 22 of the power supply unit 20 and the receiving port 32 of the support unit 30. The power supply unit 20 and the support unit 30 are not detached from the lamp 10 unless the lock release button 24 and the lock release button 34 are used. That is, once the luminaire is installed, it does not fall unless the lock is released, so that safety is high.

  FIG. 21 is a diagram illustrating a usage example of the lighting fixture in the present embodiment. FIG. 2A shows a basic usage example of the present embodiment, in which one LED tube 40 and one support unit 30 are connected to the power supply unit 20 at the position. FIG. 5B is an example in which a plurality of LED tubes 40 are used in one power supply unit 20. A plurality of LED tubes 40 can be connected to one power supply unit 20 via an extension cable 60. FIG. 2C is an example in which two LED tubes 40 according to the present embodiment are installed in a lamp of a 2.4 m straight tube fluorescent lamp. Thus, by connecting the plurality of LED tubes 40 using the connecting connector 50, the LED tubes can be attached to lamps of various lengths.

  FIG. 4D is an example in which a plurality of LED tubes 40 are connected to one power supply unit 20 using a connection connector 50 and an extension cable 60. FIG. 5E shows an example in which another power source is used without using the power source unit 20. As described above, since the power source, the support portion, and the LED tube are modularized, even if a dimensional error occurs, the error can be absorbed by a combination between modules. In addition, it is possible to provide usage methods corresponding to various needs by combining the modules. As shown in FIG. 21, it can be applied to special uses such as 110W + 40W and 40W + 20W for a factory store, etc., a DC power supply device, a separate power supply, etc. Moreover, since it is modularized, the user only needs to replace the broken part.
