<First Embodiment>
1. Configuration FIG. 1 is a perspective view of an LED lamp according to an embodiment, in which a portion of a glass tube is cut away so that the inside can be seen. 2 is a cross-sectional view of the central portion of the LED lamp, and FIG. 3 is a view of the LED lamp viewed from the direction of arrow A in FIG.

The LED lamp 1 is a type that is mounted on a fluorescent lamp fixture for a straight tube fluorescent lamp.
The LED lamp 1 includes a long glass tube 3 as a holder, a holder 5 disposed in the glass tube 3, a plurality of LED modules 7 held in the holder 5, and the holder 5 in the glass An adhesive 9 (see FIG. 2) that joins (fixes) the tube 3 in contact with the tube 3, a base 11 that is attached to both ends of the glass tube 3, and a power supply via the base 11 to receive the LED module 7. A lighting circuit 13 (see FIGS. 5 and 7) that emits light (lights) is provided.

  The glass tube 3 is a straight tube, for example, the cross-sectional shape is circular (refer FIG. 2). As for the glass tube 3, the outer peripheral surface or the inner peripheral surface may be diffusion-treated, or may not be natural. In addition, this glass tube 3 can also be comprised with the glass tube (For example, it is soda glass) utilized with the existing straight fluorescent tube.

FIG. 4 is a perspective view of a holder for mounting the LED module.
The holder 5 has a long structure corresponding to the long glass tube 3. As shown in FIGS. 2 and 4, the holder 5 includes a rail member 17 having a groove 15 extending in the longitudinal direction, that is, a C-shaped rail member (also referred to as “C-shaped rail”). Then, the LED modules 7 are sequentially inserted into the rail member 17 from both end openings of the rail member 17.

Here, the light emitted from the LED module 7 is emitted to the outside of the holder 5 through the groove 15, and there is no light shielding member for shielding this light.
Here, the rail member 17 has a laterally long rectangular shape in cross section, and has a groove 15 on a wall corresponding to one of a pair of long sides. That is, the cross-sectional shape is C-shaped with the opening on top. Note that, as in the present embodiment, a shape in which a part of a rectangular shape is open and the corners are angular is included in the C-shape.

  Of the walls corresponding to the long sides, the side where the grooves 15 are present (the wall on the side from which light is emitted) is the front wall 19, and the side where the grooves 15 are not present is the back wall 21. . Further, both the front wall 19 and both side portions of the groove 15 are defined as a first portion 19a and a second portion 19b (simply referred to as “front walls 19a and 19b”). The walls corresponding to the short sides are referred to as a first side wall 23 and a second side wall 25.

  The rail member 17 is made of, for example, an insulating material, aluminum, or the like, and a power supply path for supplying power to the LED module 7 on the back side (that is, the inner surface) of the first portion 19a and the second portion 19b of the front wall 19. 27a and 27b are on the back side (that is, the inner surface) of the first side wall 23, and conductive paths 29 described later along the grooves 15 (that is, in the direction (longitudinal direction) in which the central axis of the rail member 17 extends). It is along.) It is provided continuously.

  As shown in FIG. 2, the holder 5 is a glass in a state of bridging (stretching) two locations (for example, “B1” and “B2” in FIG. 2) which are the inner surfaces of the glass tube 3 and are separated from each other. The adhesive 9 is disposed between the outer surface 21 a of the back wall 21 of the holder 5 and the inner surface 3 a of the glass tube 3 while being disposed in the tube 3 and maintaining this cross-linked state. The adhesive 9 is filled between the holder 5 and the glass tube 3 by being injected between the holder 5 and the glass tube 3, for example.

  As shown in FIG. 4, the LED module 7 includes a substrate 33 having a wiring pattern 31 on the surface, a plurality of LEDs 35 mounted on the surface of the substrate 33, and a sealing body 37 that seals the plurality of LEDs 35. , In an independent form (that is, independently portable).

  In FIG. 4, the number of LEDs 35 mounted on one LED module 7 is four in total including the one covered with the sealing body 37, but the number of LEDs is not limited to this. In addition, since the light emitted from the LED 35 is emitted from the sealing body 37 as a result, the area where the sealing body 37 exists is also a “light emitting area”.

  The substrate 33 is made of an insulating material (for example, ceramic) and has a size to be inserted into the holder 5. The wiring pattern 31 includes a connection portion 39 for connecting a plurality of LEDs 35 mounted on the substrate 33 in series, and power supply paths 27 a and 27 b of the holder 5 when the LED module 7 is held (mounted) by the holder 5. Terminal portions (also called “power receiving terminals”) 41a and 41b that are electrically connected to each other.

  The sealing body 37 is made of, for example, a translucent resin (for example, a silicone resin) or the like, and when it is necessary to convert the wavelength of light emitted from the LED 35, the wavelength conversion of phosphor powder or the like is performed. A material having a function is mixed in the translucent resin.

For example, in the case where white light is emitted from the LED module 7 using a GaN system that emits blue light as the LED 35, (Ba, Sr) ₂ SiO ₄ : Eu ²⁺ yellow-green phosphor powder and Sr ₂ are used as the phosphor powder. Si ₅ N ₈ : Eu ²⁺ red phosphor powder is used.

In addition, when it is necessary to convert the wavelength of the light emitted from LED35, it can implement also by forming the fluorescent film containing fluorescent substance powder on the internal peripheral surface of a glass tube, for example.
The terminal portions 41 a and 41 b are formed on the main surface of the substrate 33 and exposed to the outside air at portions where the sealing body 37 is not formed (also “shoulders”).

  In a state where the LED module 7 is inserted into the holder 5, a pressing plate 43 that presses the LED module 7 against the front wall 19 is inserted between the holder 5 and the LED module 7. The pressing plate 43 has a heat transfer function that transfers heat generated when the LED module 7 (LED 35) emits light to the holder 5. For this reason, as the pressing plate 43, it is preferable to use a material having high heat conductivity. Furthermore, it is preferable to use a material having a small specific gravity in consideration of weight reduction.

  In the state where the LED module 7 is inserted into the holder 5, a spacer (for adjusting the interval between the LED modules 7, 7 is provided between the adjacent LED modules 7, 7 as shown in FIGS. It is also a “spacer member.”) 45 is provided.

The lead wires 59 and 61 connected to the caps 11 and 11 extend from the outer surfaces of the flange portions 55 and 57.

  The adhesive 9 has a bonding function for bonding the holder 5 into the glass tube 3 and a heat transfer function for transmitting heat generated during light emission of the LED module 7 (LED 35) from the holder 5 to the glass tube 3. For this reason, it is preferable to use a highly heat-conductive material as the adhesive 9. Furthermore, it is preferable to use a material having a small specific gravity in consideration of weight reduction.

  The heat transfer function is realized by joining the holder 5 to the inner surface 3a of the glass tube 3 via the adhesive 9 in a state where the holder 5 is in contact with the inner surface of the glass tube 3 (more precisely, two points in the cross section). Is done. That is, the edge of the holder 5 extending in the longitudinal direction (corresponding to “B1” and “B2” in FIG. 2) is in contact with the inner surface 3 a of the glass tube 3, and the surface of the back wall 21 that is the back surface of the holder 5. An adhesive 9 exists between the outer surface and the lower surface in FIG. 2 and the inner surface 3 a of the glass tube 3.

  As shown in FIG. 1, the base 11 is a G-type base used in a straight tube fluorescent lamp. However, other types of caps, for example, caps such as G10q, GX10q, and GY10q, and P caps may be used, and they may be appropriately determined in accordance with a lighting apparatus to which a target fluorescent lamp or LED lamp is attached.

FIG. 6 is an enlarged cross-sectional view of an end portion of the LED lamp.
The base 11 includes a bottomed cylindrical base body 63 and a pair of base pins 69 extending outward from the outer surface of the bottom 65 of the base body 63. The base body 63 has a cylindrical portion 67 and a bottom portion 65, and the base pin 69 is attached to the base body 63 via a fixture 66 attached to the inner surface of the bottom portion 65 of the base body 63. .

  As shown in FIG. 6, the base 11 is detachably attached to the end of the glass tube 3 via an adapter 71. The adapter 71 is a cylinder that matches the shape of the inner peripheral surface of the glass tube 3, and the outer peripheral surface on one end side (side closer to the center of the glass tube) is fixed to the inner peripheral surface of the glass tube 3 with an adhesive 73. .

  Screws that are screwed to each other are formed on the outer peripheral surface on the other end side of the adapter 71 and the inner peripheral surface of the cylindrical portion 67 of the base body 63, and the base 11 is screwed to the other end of the adapter 71. The base 11 is detachably attached to the end of the glass tube 3.

FIG. 7 is a circuit diagram relating to an LED lamp.
The plurality of LED modules 7 are electrically connected in parallel to the power supply paths 27a and 27b.

  The lighting circuit 13 is a rectifier circuit as shown in FIG. Here, a diode bridge 77 using four Zener diodes 75 is used as the rectifier circuit, and is mounted on the outer surface (front surface) of the fitting portion 51 of the pressing member 47 as shown in FIG.

  The input end of the lighting circuit 13 is connected to the base pin 69 via lead wires 59 and 61 with the pair of base pins 69 of the base 11 short-circuited. The electrical connection between the lead wires 59 and 61 and the base pins 69 and 69 is performed by, for example, melting solder in the base pins 69 and 69 in a state where the lead wires 59 and 61 are inserted into the base pins 69 and 69. It is done by pouring. Of course, the lead wire and the base pin may be connected by other methods such as caulking.

The lighting circuit 13 and the lead wire 61 are connected via a conductive path 81 formed on the outer surface (front surface) of the fitting portion 51 of the pressing member 47 and a conductive path 29 on the inner surface of the side wall 23 of the rail member 17. It has been broken.

  The output end of the lighting circuit 13 is connected to power supply paths 27 a and 27 b provided on the back surface of the front wall 19 of the rail member 17 via conductive paths 83 and 85 formed on the outer surface of the fitting portion 51. Has been.

It is connected via a power supply path 27a provided on the back surface.
2. Manufacturing Method An example of the manufacturing method of the LED lamp 1 according to the first embodiment will be described.

  First, the glass tube 3 according to the LED lamp 1 is prepared, and the adapter 71 is fixed to the end of the glass tube 3 with an adhesive 73. At this time, even if the adhesive 73 (for example, cement) is used, the LED (35) is not yet present in the glass tube 3, so the LED (35) can be heated even when the adhesive is cured. There is no risk of heat damage.

  Next, a holder 5 that matches the entire length of the glass tube 3 is prepared. At this time, the holder 5 to be prepared can hold the LED module regardless of the specification of the target fluorescent lamp as long as the size of the LED module 7 mounted on the holder 5 is constant.

  For this reason, what is necessary is just to cut out from the elongate member used as the holder 5 so that it may respond | correspond to the LED lamp 1 matched with the specification of the fluorescent lamp made into object, and can make the specification (standard) of the holder 5 common ( This can reduce the cost of parts.)

Next, the holder 5 is mounted in the glass tube 3. Specifically, the mounting is performed in a state in which the edge on the back side of the holder 5 (B1 and B2 in FIG. 2) is in contact with the inner surface 3a of the glass tube 3.
As a method of mounting, in addition to injecting an adhesive into the gap between the holder 5 and the glass tube 3, for example, the holder 5 with the adhesive 9 applied to the mounting surface (the outer surface of the back wall 21) is made of glass. After being inserted into the tube 3, the edge on the back surface side of the holder 5 (“B1” and “B2” in FIG. 2) is pressed so as to contact the inner surface 3 a of the glass tube 3. There is a method of holding and curing the adhesive 9 (for example, heat curing).

  Then, a predetermined number of LED modules 7 and spacers 45 are alternately inserted into the holder 5 mounted in the glass tube 3 from the end (opening) of the rail member 17. At this time, the LED module 7 having the same specification can be used as the LED module 7 to be inserted into the holder 5, and the specification (standard) of the LED module can be made common (this can reduce the cost of components). ).

  In particular, the spacer 45 has a width for insertion into the holder 5 (a dimension in a direction parallel to the main surface (surface) of the spacer 45 and perpendicular to the insertion direction into the holder 5, and the horizontal direction in FIG. 2. And the height (the dimension in the direction perpendicular to the main surface (surface) of the spacer and the dimension in the vertical direction in FIG. 2) is constant (that is, the cross-sectional shape is the same). Can be cut out to a predetermined length so as to correspond to the target fluorescent lamp (that is, the specification (standard) of the spacer 45 can be shared). . Thereby, cost reduction of components can be achieved.

  After the LED module 7 and the spacer 45 are inserted into the holder 5, the pressing plate 43 is inserted between the LED module 7 and the back wall 21 of the holder 5 and between the spacer 45 and the back wall 21 of the holder 5 (when inserting) The LED module 7 may be turned downward.)

  Thereby, the LED module 7 is pressed against the front wall 19 side of the holder 5, and the terminal portions 41 a and 41 b come into contact with the power supply paths 27 a and 27 b of the holder 5. The pressing plate 43 can also share parts with the holder 5 and the like.

  Thereafter, the fitting portions 51 and 53 of the pressing members 47 and 49 are fitted to the end portions of the rail member 17 of the holder 5. Thereby, positioning with respect to the holder 5 of the LED module 4 is made, and electrical conduction between the LED module 7 and the pressing members 47 and 49 is ensured.

At this time, if the holder 5 having the same specification is used as the LED lamp 1 even if the specification of the target fluorescent lamp is different, the pressing members 47 and 49 having the same specification can be used.
Finally, the base body 63 is screwed onto the adapter 71 (71) at the end of the glass tube 3 while the lead wires 59 61 extending from the holding members 47 49 are electrically connected to the base pin 69. To wear.

Thereby, the base 11 and the LED module 7 are electrically connected, and the LED lamp 1 is completed. At this time, if the glass tube 3 having the same inner diameter is used as the LED lamp 1, the adapter 71 and the base 11 having the same specification can be used even if the specifications of the target fluorescent lamp are different.
3. Usage example The usage example of the LED lamp 1 is demonstrated concretely.

  In the LED lamp 1 having the above configuration, when one LED module 7 of the plurality of LED modules 7 is not lit (emitted), a method for replacing the LED module that is not lit will be described.

  First, one of the caps 11 and 11 attached to the adapters 71 at both ends of the glass tube 3 is removed. In this description, the base 11 connected to the lead wire 59 is removed in order to refer to FIG. The lead wire 59 is removed from the base pin 69 by heating the base pin 69 and melting the solder in the base pin 69.

  When the base 11 is removed, the pressing member 47 and the pressing plate 43 fitted in the opening at the end of the holder 5 are removed and removed from the holder 5. Thereby, the LED module 7 and the spacer 45 inserted in the holder 5 can be moved.

  Next, the LED module 7 and the spacer 45 are sequentially taken out from the end of the holder 5 (the end of the glass tube 3), and the LED module 7 to be replaced is taken out. Then, instead of the LED module 7 to be replaced (taken out), a normal LED module 7 for replacement is inserted into the holder 5, and the LED module 7 and the spacer 45 that have been normally lit up so far are inserted into the holder 5. Insert sequentially.

Then, the holding plate 43 is inserted into the holder 7, and the holding member 47 is fitted into the holder 7. Finally, the base 11 is attached to the glass tube 3 while electrically connecting the lead wire 59 of the holding member 47 and the base pin 69. Then, the replacement of the LED module 7 is completed. As described above, in the LED lamp 1 according to the first embodiment, the LED module 7 can be easily replaced even after the lamp 1 is assembled, and other parts / members having no abnormality can be used as they are. Can be reused.

<Third Embodiment>
In the first and second embodiments, the LED is mounted on the main surface of the substrate, and the LED module is mounted on the holder so that the position of the LED is constant. That is, since the LED module is held by the holder in a fixed posture, it irradiates only a predetermined fixed direction.

However, the posture of mounting the LED module on the holder may not be constant, and an LED lamp having a different posture of the LED module will be described below as a third embodiment.

It is recessed in the truncated cone shape without being recessed in the truncated octagonal pyramid shape.

FIG. 11 is an enlarged cross-sectional view of one end side of the LED lamp.
As shown in FIG. 11, the adapter 211 is attached to the inner surfaces of both ends of the glass tube 3. The adapter 211 can be attached to the glass tube 3 with, for example, an adhesive.

  The adapter 211 includes a holding portion 231 that holds the holder 205 and a mounting portion 233 for mounting the base member. The adapter 211 has a cylindrical shape, and the center side of the glass tube 3 is a holding portion 231, and the end portion side of the glass tube 3 is a mounting portion 233.

  The holding portion 231 holds the holder 205 when the cylindrical inner peripheral surface 231 a coincides with the outer peripheral surface of the holder 205 and is fitted to each other. In addition, the shape of the inner peripheral surface 231a of the holding portion 231 is only required to be able to hold the holder 205. For example, in the case of the holder 205 having a regular octagonal outer peripheral shape, a shape that makes contact with at least two sides passing through the center and facing each other. (For example, a regular octagon is a circumscribed square shape).

  As with the first embodiment, the mounting portion 233 has a cylindrical shape as a whole, and an inner peripheral surface thereof is a screw 233a. A screw (261) that is screwed to the screw 233a is formed on the base member 209, and the mounting portion 233 attaches the base member 209 in a detachable manner by screwing them together.

  The base member 209 includes a base 249 having a base pin 247 and a connection member 251 that attaches the base member 209 to the adapter 211 and mechanically / electrically connects the LED modules 207A and 207B.

The base 249 includes a bottomed cylindrical base body 253 and a base pin 247 provided on the base body 253. The base 249 is G-shaped.
The connecting member 251 has a bottomed cylindrical shape, and a fixing portion 257 that is fixed to the base body 253 of the base 249, a mounting portion 255 that is attached to the adapter 211, and a connection portion 259 that is connected to the LED module 207 or the spacer. With.

  The connecting member 251 has a large-diameter portion, a small-diameter portion, and a bottom portion. The large-diameter portion is a fixing portion 257 and the small-diameter portion is a mounting portion 255, and the connecting portion 259 is a portion protruding from the bottom portion. The mounting portion 255 includes a screw 260 that is screwed into the screw 233a of the adapter 211.

  The connecting portion 259 includes a connecting portion 261 that connects to the connecting portion 221A of the LED module 207A. The connection part 261 is provided corresponding to the connection part 221A of the LED module 207A and the connection part 223B of the LED module 207B.

  Again, the connection portion 261 is recessed in a truncated cone shape corresponding to the connection portion 221A of the LED module 207A, and the annular shape along the axial center has three conductive portions (“221a” and “221b” in FIG. 10). "Corresponding to" 221c ").

Here, the LED module 207 </ b> A and the base member 209 have a circular cross-sectional shape of the connection part 221 </ b> A of the LED module 207 </ b> A and the connection part 261 of the base member 209. It can be rotated to screw together. The other base member has basically the same configuration as the base member 209 described above.
2. Others In the above description of the third embodiment, the plurality of LED modules 207 are held by the holder 205 so that the postures of the LED modules 207 are different from each other. However, the cross-sectional shape may be held by the polygonal shape holder in the same posture. .

FIG. 12 is a diagram illustrating a modification example according to the third embodiment.
As shown in the figure, the LED lamp 271 includes a glass tube 3, a holder 205, an LED module 273, and the like. The holder 205 has the same configuration as the holder 205 described in the third embodiment, and is held on the glass tube 3 by the adapter 211.

  The LED module 273 is provided on a box-shaped module main body 275, light emitting portions 277a and 277b formed on the front and back surfaces of the module main body 275, and both end faces orthogonal to the central axis direction of the holder 205 in the module main body 275. Conductive portions 279a and 279b are provided. Note that the conductive portion 279b does not appear in FIG.

  The light emitting units 277a and 277b are composed of a plurality of LEDs mounted on the front and back surfaces of the module main body 275 and a sealing body that covers these LEDs. The area where the light emitting portions 277a and 277b exist is also a light emitting area.

  Here, the module main body 275 has a box shape, but may naturally be a plate shape such as a substrate. In particular, when the thickness of the substrate is thin, it is preferable from the viewpoint of heat dissipation that the mounting positions of the LEDs are different on the front and back sides of the substrate. That is, it is preferable to disperse and mount the front and back LEDs so that the heat of the LEDs is transmitted to the entire substrate.

  Similarly to the conductive portions 221 and 223 of the third embodiment, the conductive portions 279a and 279b have shapes (structures) that fit into the conductive portions 279b and 279a of other adjacent LED modules. The shape is rectangular and has an uneven shape that becomes thinner as it goes away from the end face.

  However, if the holder is a cylinder having a polygonal cross-sectional shape and the width of the LED module matches the distance between the opposing inner surfaces of the holder, the LED module is not likely to rotate in the holder. The outer peripheral shape of the cross section of the part can also be configured in a circular shape.

  Further, when it is not necessary to change the attitude of the LED module, for example, when a cylindrical body having an elliptical cross-sectional shape is used as the holder, the distance between the inner surfaces corresponding to the major axis of the holder (the major axis) The LED module is held by the holder.

FIG. 13 is a diagram illustrating another modified example according to the third embodiment.
In the above description of the third embodiment, the LED module 207 has a box shape having six sides. However, the LED module 207 may have a different shape, and the cross-sectional shape of the holder may not be a polygon.

  As shown in the figure, the LED lamp 281 includes a glass tube 3, a holder 283, an LED module 285, an adapter 287, and the like. The holder 283 is held by an adapter 287 having a circular through hole at the center. In addition, when the LED module 285 is held so as not to rotate by a base member or the like, no particular problem occurs even if the holder rotates.

  The LED module 285 is formed in a triangular prism (including both solid and hollow concepts) -shaped module main body 289, and the cross-sectional shape of the module main body 289 is formed on each side surface corresponding to each side having a triangular shape. The light emitting portions 291, 291 and 291, and the conductive portions 293 a and 293 b provided on both end surfaces of the module main body 285 are provided. Note that the conductive portion 293b does not appear in FIG. In addition, the region where the light emitting unit 291 exists is also a light emitting region.

  Similarly to the conductive portions 221 and 223 of the third embodiment, the conductive portions 293a and 293b have shapes (structures) that fit into the conductive portions 293b and 293a of other adjacent LED modules. The shape is rectangular and has an uneven shape that becomes thinner as it goes away from the end face.

Here, the cross-sectional shape of the conductive portions 293a and 293b is a triangular shape, but may be a polygonal shape that is equal to or greater than the triangular shape. In order to make the postures of the LED modules 285 different, the cross-sectional shapes of the conductive portions 293a and 293b may be made to be a polygonal shape that is equal to or greater than a square shape and connected so that the postures of adjacent LED modules are different.
<Modification>
Although the present invention has been described based on the above-described embodiments, the contents of the present invention are not limited to the specific examples shown in the above-described embodiments. Various modifications can be implemented.
1. Glass tube In the said embodiment, although the cross-sectional shape of the glass tube 3 was annular, other cross-sectional shapes may be sufficient. The other shape may be a polygonal ring such as a triangle or an elliptical ring. When using an elliptical glass tube, a wide holder can be used if the width of the holder is matched with the major axis of the ellipse in the cross section of the glass tube. Note that a cylindrical body using a translucent material (for example, a ceramic material or a resin material) can be used instead of the glass tube.
2. LED Module In the above embodiment, the LED modules 7, 107, 207 are of one type (meaning that the specifications of the LED modules held by the holders 5, 105, 205 are the same). The plurality of types of LED modules having different lengths in the insertion / extraction direction for inserting / removing the holders 5, 105, 205 are prepared, and the plurality of types of LED modules are alternately inserted into the holders. The pitch may be adjusted. Thereby, for example, the use of the spacer 45 described in the first embodiment can be eliminated.

  The LED module has a square shape in plan view, but may have other shapes. Other shapes may be polygonal shapes (including chamfered shapes, rounded corners removed) such as circular, rectangular, and triangular shapes in plan view. Some of them may have an arc shape. In addition, when holding an LED module by sliding with respect to a holder, the shape which is easy to slide is preferable.

  The LED modules 7 and 107 in the first and second embodiments have LEDs mounted on one main surface of the substrate, and the LED module 207 in the third embodiment has front and back main surfaces of the module main body 213. The LED was mounted on.

However, the LED module only needs to be mounted with LEDs, and is not limited by the shape of the mounting surface, the number of mounting surfaces, the number of LEDs mounted on one LED module, or the like. For example, the LED may be mounted on an arc-shaped substrate (module body), or the cross-sectional shape may be a polygonal shape, and the LED may be mounted on all or part of the plurality of sides.
3. Number of holders (1) In each of the above embodiments, one holder 5, 105, 205 is inserted and arranged in the glass tube 3, but, for example, a connection for mechanically and electrically connecting a plurality of holders. It is good also as one continuous holder using a member. In this case, the holder used in the other LED lamps can be taken out and used for other long LED lamps, and the members can be reused.
(2) Cross-sectional shape The cross-sectional shape of a holder is not limited to the shape demonstrated in embodiment, Other shapes may be sufficient. Other shapes will be described.

FIG. 14 is a diagram showing a first modification of the cross-sectional shape of the holder.
(A) Example 1
In the holders 5 and 105 according to the first and second embodiments, rail members 17 and 115 having grooves 15 and 113 extending in the central axis direction are used on the front wall 19, and the front wall 19 is connected to the back wall 21. Although it was parallel, the front wall may be inclined with respect to the back wall as shown in FIG.

  The holder 301 according to Example 1 of the first modification has a groove 305 at the approximate center of the front wall 303, and the front wall 303 is inclined so as to approach the back wall 307 as the distance from the groove 305 increases. In the LED module 311, the upper surface 313 a of the substrate 313 is inclined along the inner surface (back surface) of the front wall 303 in accordance with the internal shape of the holder 301.

The shape of the LED module 311 is not particularly limited as long as it is held in the holder 301. For example, the shape of the LED modules 7 and 107 described in the first and second embodiments may be used. .
(B) Example 2
In the first to third embodiments, the LED modules 7, 107, and 207 are inserted and held in the holders 5, 105, and 205. However, the holder holds a plurality of LED modules in the longitudinal direction (glass tube For example, a holder having protrusions continuous in the longitudinal direction as shown in FIG. 14B.

  The holder 331 according to the second example of the first modification includes a base 333 and a protrusion 335 formed on the surface side of the base 333. The projecting portion 335 is formed continuously in the longitudinal direction of the holder 331, and has a trapezoidal shape in which the upper base is longer than the lower base.

  On the other hand, the LED module 341 according to Example 2 includes a substrate 343, an LED (not shown) mounted on the surface of the substrate 343, and a sealing body 345 formed on the main surface of the substrate 343 and covering the LED. Prepare.

  The substrate 343 has a groove 347 whose rear surface is fitted into the protruding portion 335 of the holder 331. That is, the cross-sectional shape of the groove 347 has a trapezoidal shape (there is a groove shape) in which the upper base is longer than the lower base.

  Accordingly, when the protruding portion 335 of the holder 331 is fitted into the groove 347 of the LED module 341, the LED module 341 is held (mounted) along the central axis direction of the holder 331.

  Needless to say, the holder 331 and the LED module 341 are fitted by sliding the LED module 341 relative to the holder 331 in a state where the end of the groove 347 and the end of the protrusion 335 are aligned. Done.

Since the width in the cross section of the protrusion part 335 and the groove | channel 347 becomes narrow as it moves to the holder 331 side from the LED module 341, it can prevent that the LED module 341 remove | deviates from the holder 331.
(C) Example 3
In the first example and the second example, the LED modules 311 and 341 and the holders 301 and 331 are fitted to each other (highly conceptually “engaged”). , 331, the LED module may be held by the holder by a structure other than the fitting structure. For example, as shown in FIG. 14C, the LED module is supported by a shaft extending in the longitudinal direction. Alternatively, the LED module may be held and held by a holding plate.

  The holder 351 according to the third example of the first modification has a base 353 that has a U-shaped cross section and extends along the axis of the glass tube, and is attached to both ends of the base 353 in the cross section. A shaft support portion (not shown) for supporting a pair (two) of shafts 355 and 355 parallel to the central axis of 353, and supported by the shafts 355 and 355 and rotatable around the shafts 355 and 355. Holding plates 357 and 357 are provided.

Conductive paths 359a and 359b that are connected (contacted) with the terminal portions 363 and 363 of the LED module 361 are formed on the back surfaces of the pressing plates 357 and 357 as in the first embodiment.
(3) Material Although aluminum is used in the description of the above embodiment, other materials can also be used. Examples of other materials include ceramic materials and resin materials such as epoxy and silicone. From the viewpoint of efficiently transferring the heat generated by the LED to a glass tube or adhesive, a highly heat-conductive material is used. It is preferable to use, for example, paper phenol or the like can be used, and naturally, the same material as the substrate of the LED module can also be used. Moreover, the heat load to LED can further be reduced by using metal substrates with high heat conductivity, such as an aluminum substrate and a copper substrate.

  On the other hand, from the viewpoint of weight reduction, it is preferable to use a material such as a resin material. In addition, although mentioned later, if a LED module can be hold | maintained so that insertion or extraction is possible from the edge part (and edge part of a glass tube), for example, a glass material (it is a glass tube, refer 3rd Embodiment etc.) will be utilized. You can also

(1) Structure FIG. 16 is a cross-sectional perspective view of an LED lamp according to Modification 3, and FIG. 17 is a cross-sectional view of a central portion of the LED lamp.

  As in the first embodiment, the LED lamp 501 according to Example 1 of Modification 3 includes a glass member 503 as a long globe 502 and a holder partially disposed inside the glass member 503. 505, a plurality (only one appears in FIG. 16) of LED modules 7 and spacers 45 held by the holder 505, and a base 506 attached to both ends of the glass member 503 (not shown) 1), and a lighting circuit 13 (not shown, but refer to FIGS. 5 and 7) that receives power through the base 506 and emits (lights) the LED module 7.

Here, the members having the same reference numerals as those described in the first embodiment have the same configuration as the members described in the first embodiment, and a description thereof is omitted here.
As can be seen from FIGS. 16 and 17, the glass member 503 has a C shape, and its opening edges 503 a and 503 b are attached to the holder 505. Here, the opening edge portions 503a and 503b are portions extending in the longitudinal direction of the glass member 503, and are both side portions of the opening 507 forming a C shape in the cross section. Here, although the glass member (glass material) 503 is used for the globe 502, it may be made of other translucent material, for example, polycarbonate (PC) resin.

  As shown in the figure, the holder 505 has a C-shaped cross section, more specifically, an annular shape having a rectangular cross section, and a groove (opening) 15 formed on one long side. It is comprised by the character-shaped rail member. Inside the holder 505, there is a space for the LED module 7 and the spacer 45 to be inserted and removed.

  The holder 505 is the first embodiment in that the mounting groove 511.511 for mounting the glass member 503 is formed on the side walls 509 and 509 of the rail member (wall corresponding to the short side of the rectangle in the cross section). Unlike the holder 5 of the form, the other configuration is basically the same as the holder 5.

  That is, the glass member 503 is attached to the holder 505 by fitting the opening edges 503 a and 503 b of the glass member 503 into the attachment grooves 511 and 511 of the side walls 509 and 509 of the holder 505.

  The mounting method of the glass member 503 and the holder 505 includes, for example, positioning opening edge portions 503a and 503b on one end side in the longitudinal direction of the glass member 503 and mounting grooves 511 and 511 on the other end side in the longitudinal direction of the holder 505. In this state, at least one of the glass member 503 and the holder 505 can be pushed (slid) into the other side.

  For example, in the case where the globe 502 is formed of a resin material capable of making the width of the opening 507 of the globe 502 larger than the width of the holder 505 by elastic deformation in the cross section, the holder with the width of the opening 507 of the globe 502 widened. Both can be mounted by fitting 505 into the opening 507.

  The base 506 includes a bottomed cylindrical base body and a pair of base pins extending outward from the outer surface of the bottom part of the base body, and a screw is formed on the outer peripheral surface of the base body (first See embodiment). The base pin is attached to the base body via a fixture 66 attached to the inner surface of the bottom of the base body.

  As in the first embodiment, holding members 47 and 49 are fitted to both ends of the holder 505, and lead wires 59 and 61 and caps 506 and 506 led out from the holding members 47 and 49. Is connected.

  A bottomed cylindrical adapter 515 is fixed to both ends of the glass member 503 with an adhesive (not shown). The adapter 515 is attached to the outer periphery of the glass member 503 so as to cover the end of the glass member 503 and the pressing members 47 and 49. For this reason, a hole corresponding to a portion of the glass member 503 and the pressing members 47 and 49 that protrude from the opening 507 of the glass member 503 is formed at the bottom of the adapter 515. Even when the adapter 515 is attached to the end of the glass member 503, the LED module 7 and the spacer 45 can be inserted and removed.

A screw that is screwed to a screw formed on the outer peripheral surface of the base body of the base 506 is formed on the inner periphery of the cylindrical portion of the adapter 515, and the base 506 is detachably screwed to the adapter 515. Yes.
(2) Globe shape Since the LED lamp 501 according to the first modification example 3 assumes a shape close to a straight tube fluorescent lamp as the shape of the lamp, a part of the glass member 503 (the periphery of the opening 507 portion) Part) is flat.

However, even if it is an alternative to a straight tube fluorescent lamp, the globe shape need not be the same as that of the straight tube fluorescent lamp, and may be other shapes.
Hereinafter, the shape of the glove different from Example 1 of Modification 3 will be described. The globe can be formed without depending on the material, such as glass material, resin material, ceramic material, etc. regardless of its shape, but the width of the opening of the globe should be larger than the width of the holder by elastic deformation. In order to be able to do this, it is limited to a resin material, a combination of a metal (thin wall) and a translucent resin.

FIG. 18 is a diagram illustrating a modified example of the shape of the globe.
The LED lamp 531 shown in FIG. 5A includes a globe 533, a holder 535, an LED module 7, a base, a lighting circuit, and a spacer, a pressing member, and an adapter as necessary.

  As shown in FIG. 5A, the globe 533 has a rectangular C-shaped cross section and an opening 539 in a wall 537 corresponding to one long side. The globe 533 is attached to the holder 535 by opening edge portions 542a and 542b located on both sides of the opening 539 in the cross section being fitted into attachment grooves 546 and 546 formed on the side wall of the holder 535.

  The LED lamp 551 shown in FIG. 5B includes a globe 553, a holder 555, an LED module 7, a base, a lighting circuit, and a spacer, a pressing member, and an adapter as necessary.

  As shown in (b) of the figure, the globe 553 has a half cross-sectional shape (an imaginary line perpendicular to the long axis in the cross-section (here, a line extending to the left and right)). The shape is as if it was cut. In other words, it is U-shaped. Ends on the opening side constituting the U-shape (ends of a pair of parallel lines and opposite to the side connected by the arc) 558a and 558b are on the holder 555. It is inserted into mounting grooves 564 and 564 formed in the wall 561.

  The mounting grooves 564 and 564 of the holder 555 have a so-called dovetail shape in which the dimension on the back side (lower side in the figure) is larger than the dimension of the entrance (upward side in the figure) in the cross section. is doing. On the other hand, end portions 558a and 558b on the opening side of the globe 553 bulge out in a circular shape and have dimensions and shapes larger than the entrances of the mounting grooves 564 and 564.

  For this reason, the end portions 558a and 558b on the opening side of the globe 553 are not allowed to be inserted into the inside of the mounting grooves 564 and 564 from the entrance side, and even if the globe 553 is positioned on the lower side. The globe 553 does not fall from the holder 555.

  As an example of the method of attaching the glove to the holder shown in (a) to (b) of the figure, for example, the opening edge part on one end side in the longitudinal direction of the glove and the end part on the opening side, and the longitudinal direction of the holder The mounting groove on the other end side is aligned, and in this state, at least one of the globe and the holder can be pushed (slid) into the other side.

  The LED lamp 571 shown in FIG. 5C includes a globe 573, a holder 575, an LED module 7, a base, a lighting circuit, and a spacer, a pressing member, and an adapter as necessary.

  The globe 573 has an inverted trapezoidal cross-sectional shape, and has a C-shape in which the central portion of the lower wall 577 corresponding to the lower bottom not facing the LED module 7 is opened. In the cross section of the globe 573, portions located on both sides of the opening 579 are bent inward (inward), and the opening edges 582a and 582b extend inward.

  The holder 575 is outward from the lower wall (a wall on the back side facing the wall on which the opening 579 of the globe 573 is formed) 585 (also on the lower side and in the direction in which the opening 579 of the globe 573 is present). And a mounting protrusion 587 that protrudes toward the center. In the cross section, the width of the mounting protrusion 587 of the holder 575 is slightly larger than the width of the opening 579 of the globe 573.

  The globe 573 can be attached to the holder 575 by fitting the attachment protrusion 587 of the holder 575 into the opening 579 of the globe 573, and as described above, the opening edge 582a on one end side in the longitudinal direction of the globe 573. , 582b and the mounting protrusion 587 on the other end side in the longitudinal direction of the holder 575, and in this state, at least one of the globe 573 and the holder 575 is pushed (slid) into the other side.

The globe 573 is made of a material that can be elastically deformed to the width of the opening 579 to the width of the mounting protrusion 587 of the holder 575, for example, a resin material.
5. Adhesive In each of the above embodiments, cement is used as the adhesive 9, but another adhesive may be used, for example, a silicone resin may be used. However, in consideration of heat transfer as a function of the adhesive, it is preferable to use a material having high heat transfer, and specifically, the heat conductivity is preferably 1 [W / m · K] or more.

  In addition, in order to improve the heat conductivity of the adhesive, inorganic particles may be mixed in the adhesive. Examples of such inorganic particles include metal particles such as silver, copper, and aluminum, and nonmetal particles such as alumina, aluminum nitride, silicon carbide, and graphite.

In view of weight reduction, it is preferable to use a material having a low specific gravity. Specifically, the specific gravity is preferably 2 [Kg / m ³ ] or less. Examples of such a material include a silicone resin.
6). Sealed body (translucent resin)
In each of the above embodiments, the silicone resin is used as the translucent resin constituting the sealing bodies 37 and 119, but another material may be used. Another material is glass or the like.

In each embodiment, the phosphor powder mixed in the translucent resin is yellow (Ba, Sr) ₂ SiO ₄ : Eu ²⁺ or Y ₃ (Al, Ga) ₅ O ₁₂ : Ce ³⁺ . Although green phosphor powder and red phosphor powder such as Sr ₂ Si ₅ N ₈ : Eu ²⁺ and (Ca, Sr) S: Eu ²⁺ are used, other phosphor powders can also be used. .

For example, when a blue light emitting LED is used, a translucent resin of a mixture of a yellow phosphor powder and a green phosphor powder or a mixture of a red phosphor powder and a green phosphor powder may be used.
7). Lamp In each of the embodiments and the above-described modified examples, the LED lamp is modeled on a straight tubular fluorescent lamp. However, for example, an annular fluorescent lamp may be modeled. Hereinafter, an LED lamp modeled on an annular fluorescent lamp will be described as a fourth modification.
(1) Example 1
FIG. 19 is a cross-sectional perspective view of a half of the LED lamp according to Example 1 of Modification 4, and FIG. 20 is a partial plan view of the LED lamp according to Example 1 of Modification 4, with the internal state As can be seen, each member is appropriately cut out.

  The LED lamp 601 according to the first modification example 4 includes a globe 603, a holder 605, an LED module 607, a spacer 609, a base, a lighting circuit, and a connecting member 611, a cover 613, and the like, which will be described later.

  The globe 603 is, for example, two semi-annular glasses (here, the semi-annular shape refers to a semi-circular shape in a plan view and is not divided into, for example, upper and lower halves in a cross section). The tubes 603A and 603B are connected. The connection method will be described later.

  The holder 605 is fixed to the globe 603 while being inserted into the globe 603. The holder 605 is a rail member having a C-shaped cross section, has an arc shape that matches the curvature of the semicircular glass tubes 603A and 603B, and includes two rail members 605A and 605B. It is connected.

  That is, since the holder 605 is inserted into the annular glass tubes 603A and 603B, in a plan view, specifically, in FIG. 20, two arcs extending in parallel with the central axis of the glass tubes 603A and 603B. It has a belt-like shape consisting of sides. The configuration of the holder 605 other than the shape in plan view is the same as that of the holder 5 described in the first embodiment, and the cross-sectional shape is the same as that in FIG.

  The curvatures of the central axes of the semicircular glass tubes 603A and 603B are equal to each other, and the curvatures of the central axes of the rail members 605A and 605B are also equal to each other. In this example, the curvatures of the central axes of the rail members 605A and 605B coincide with the curvatures of the glass tubes 603A and 603B, and are orthogonal to the virtual plane including the central axis of the globe 603 when the glass tubes 603A and 603B are connected. When the glass tubes 603A and 603B are viewed from the direction in which the glass tubes 603A and 603B are viewed (that is, FIG. 20), the glass tubes 603A and 603B and the rail members 605A and 605B are arranged so that the central axis of the globe 603 and the central axis of the holder 605 overlap. Are mounted (coupled) in a state of being aligned.

  Since the LED module 607 and the spacer 609 are inserted from the end portion of the holder 605 to the inside, the LED module 607 and the spacer 609 have a strip shape that is curved in an arc shape corresponding to the space in the rail members 605A and 605B. The LED module 607 and the spacer 609 have the same configuration as the LED module 7 and the spacer 45 described in the first embodiment except for the shape in plan view.

  The connecting member 611 is inserted into the rail members 605A and 605B in a state of straddling both end portions on the side where the rail member 605A and the rail member 605B are connected. In addition, an extending portion that protrudes outward (downward) is formed at a substantially center in the longitudinal direction on the lower surface of the connecting member 611, and the connecting member 611 is prevented from being inserted into only one of the rail members 605A and 605B. is doing.

  The connecting member 611 has the same rigidity as the rail members 605A and 605B in order to connect the butted portions of the rail members 605A and 605B. Specifically, the metal plate is made of a resin material insert-molded inside.

  Note that the connecting member 611 is also electrically connected to the LED module 607 and the spacer 609 inserted in the holder 605, and thus has a wiring pattern similar to that of the spacer 609.

  The cover 613 is for concealing the connecting portion of the glass tubes 603A and 603B, and is made of a translucent material such as a resin material so as not to block light from the LED module 607 existing around the connecting portion. It is configured.

  The cover 613 includes a half of a connecting portion of the glass tubes 603A and 603B, for example, a lower cover member 613A located in the lower half and a top cover member 613B located in the upper half in the cross section. The lower cover member 613A and the upper cover member 613B can be joined using, for example, a locking structure, an adhesive structure, a screw structure, or the like.

  The part to which the base is attached has a gap between the glass tubes 603A and 603B in the globe 603, and a gap between the rail members 605A and 605B in the holder 605. From this gap, the LED module 7 and the spacer 609 are connected to each other. The rail members 605A and 605B can be inserted / extracted.

  The rail members 605A and 605B and the glass tubes 603A and 603B are directly and indirectly supported by the connecting member 611. However, when the connecting member 611 alone is insufficient in mechanical characteristics as a lamp, A configuration in which the rail members 605A and 605B and the glass tubes 603A and 603B are connected and supported at the portion where the base is mounted may be employed, for example, a configuration in which a plate is mounted.

An example of assembly as the LED lamp 601 will be described. Needless to say, it may be assembled in other order / method.
First, the rail members 605A and 605B are inserted into the glass tubes 603A and 603B, respectively, and the rail members 605A and 605B and the glass tubes 603A and 603B are fixed with an adhesive. Next, after the LED module 607 and the spacer 609 are inserted into the rail members 605A and 605B in the glass tubes 603A and 603B from the ends of the rail members 605A and 605B, the connecting member 611 is connected to the rail members 605A and 605B. Insert them at the end and join them together.

  The connecting member 611 is larger in size between the portion of the rail members 605A and 605B where the connecting member 611 is inserted and the portion of the connecting member 611 that is inserted into the rail members 605A and 605B. The rail members 605A and 605B can be connected by being pushed into the members 605A and 605B. The connecting member 611 and the rail members 605A and 605B may be fixed with an adhesive, or may be fixed with screws or the like.

  Then, the cover 613 is attached to the connecting portion and the base is attached. The base may be attached before or after the cover is attached. Moreover, the attachment method of a nozzle | cap | die can be implemented using the mounting | wearing technique of the nozzle | cap | die of a circular fluorescent lamp.

  Note that two glass tubes 603A and 603B to be the globe 603 and two rail members 605A and 605B to be the holder 605 are used, but three or more may be used, and the number of glass tubes and rail members may not be the same. . Furthermore, although glass tubes and rail members having the same size are used, members having different sizes may be used. That is, a plurality of arcuate glass tubes and rail members may be connected to form an annular shape as a whole except for the attachment portion of the base, and the number and size thereof are not particularly limited.

Further, when an annular fluorescent lamp is used as a model, the surface of the holder may be inclined outward at a predetermined angle or perpendicular to the annular radial direction in the shape of a glass tube.
(2) Example 2
The globe (glass tube) 603 of the LED lamp 601 according to Example 1 has the same circular shape as the cross-sectional shape of the glass tube of the annular fluorescent lamp, but may have other shapes. Here, an LED lamp 651 including a hemispherical globe will be described.

  As shown in the figure, the globe 653 has an annular shape except for the portion where the cap is mounted, and has a C-shaped cross section that is nearly semicircular. Note that the globe 653 is made of, for example, a light-transmitting material, and is made of a material, specifically a resin material, whose opening width increases to the width of the holder 633 due to elastic deformation.

  Like the globe 653, the holder 655 has an annular shape except for the portion where the cap is mounted, and has a C-shaped cross section. Specifically, the shape of the holder 655 in plan view is such that the holder 505 of the LED lamp 501 is curved so as to form an annular shape, and the cross-sectional shape thereof is the same as that of the holder 505. . As shown in FIG. 21, the holder 655 has mounting grooves 660 and 660 for mounting gloves on the side wall.

In addition, hatching is given to the location where the wiring pattern is formed.

  As shown in FIG. 23, the LED modules 657A, 657B, and 657C are arranged in this order (657A, 657B, and 657C) from the downstream side (the left side in the figure), and the LED modules 657 are adjacent to each other. It contacts with the other LED module 657, and the wiring pattern on the outer peripheral surface is electrically connected to the corresponding wiring pattern on the outer periphery of the adjacent LED module.
