The following embodiments exemplify apparatuses and methods for embodying the technical idea of the present invention, and the technical idea of the present invention is the material, shape, structure, arrangement, etc. of components. Is not specified as follows. The technical idea of the present invention can be variously modified within the technical scope defined by the claims described in the claims.
Hereinafter, an embodiment of a compact fluorescent lamp type LED lamp of the present invention will be described with reference to the drawings. 1 is an overall perspective view of the compact fluorescent lamp type LED lamp of this embodiment, FIG. 2 is an exploded perspective view of the compact fluorescent lamp type LED lamp of FIG. 1, and FIG. 3 is a compact fluorescent lamp of FIG. A sectional view of a mold lamp is shown. The compact fluorescent lamp LED lamp of this embodiment is mounted on an instrument body attached to a ceiling position, for example, a mounted position, but may be used by attaching to an instrument body such as a desk lamp. it can. This compact fluorescent lamp type LED lamp is used by connecting to a 4-pin single-side base socket such as GX10q defined in JISC7709.

  The instrument main body to which the compact fluorescent LED lamp of this embodiment is attached may be, for example, an existing one attached to a ceiling position or a new one. It is also possible to use a part of the existing one with modification. In this embodiment, an LED module is used as the light source of the lamp. As is well known, compact fluorescent lamps emit light using AC power as a power source, whereas LED modules that are diodes emit light using DC power as a power source. Since the indoor wiring is generally a commercial power source, that is, an AC power source, a compact fluorescent LED lamp using an LED module requires an AC-DC conversion circuit as a power circuit. In this embodiment, the lamp itself is a so-called built-in power compact fluorescent lamp with a built-in power supply circuit.

  The compact fluorescent lamp LED lamp of this embodiment includes a flat cylindrical main body 1, a flat dome-shaped cover 2 that covers one of the flat sides of the main body 1, and an LED substrate 3 that is attached to the cover 2 side of the main body 1. A power supply circuit 5 housed in a cylinder of the main body 1 in a state of being covered with an insulating coating 4, and an end-side cap 6 attached to one end in the longitudinal direction with the cover 2 being put on the main body 1. The main body 1 is configured to include a socket-side cap 7 attached to the other end portion in the longitudinal direction opposite to the end-side cap 6 in a state where the cover 2 is covered. 4 is a cross-sectional view of the portion near the end-side cap 6 of the compact fluorescent lamp type LED lamp of FIG. 1, and FIG. 5 is a cross-sectional view of the portion near the socket-side cap 7 of the compact fluorescent lamp-type LED lamp of FIG.

  The main body 1 of this embodiment is made of a metal such as an aluminum alloy, and is a cylindrical body having a trapezoidal cross section that slightly narrows in the lower part of the figure. The LED substrate 3 is mounted on the surface on the second side. The support plate 1 a is a rectangle that is long in the longitudinal direction of the cylindrical main body 1, and the width direction of the support plate 1 a is defined as the width direction of the main body 1. The outer surface of the support plate 1a is flat, and the holding portions 8 for pressing both ends in the width direction of the LED board 3 have a predetermined gap above the support plate 1a in the left-right direction in the drawing, that is, both sides in the body width direction. It is formed to protrude. That is, the LED substrate 3 is inserted in the longitudinal direction of the main body so as to slide into the gap between the pressing portion 8 and the support plate 1a. Further, on the both sides in the body width direction of the presser part 8 and slightly below the presser part 8 in the figure, the engaging part engages with the claw part 9 of the cover 2 so as to project outward from the main body 1 in the body width direction. 10 is formed upward in the figure. Further, a main body side claw portion 11 is formed so as to protrude from the outer side of the presser portion 8 in the main body width direction upward of the engaging portion 10 in the figure. Therefore, when the cover 2 is put on the support plate 1a side of the main body 1, the claw portion 9 of the cover 2 slides on the inclined surface of the main body side claw portion 11 of the presser portion 8 as will be described later. The claw portion 9 of the cover 2 is pressed against the inner surface of the engaging portion 10 in the width direction of the main body, and the main body 1 and the cover 2 are engaged. Note that a screw groove 12 for screwing a screw, which will be described later, to the outer side of the main body 1 in the main body width direction, that is, the outer peripheral surface of the main body 1, runs along the length of the main body 1. The screw groove 12 has a prescribed arc cross section and opens to the outside of the main body 1.

  A plurality of fins 13 a and 13 b are formed on the side plate 1 b and the bottom plate 1 c constituting the leg portion and the bottom side of the trapezoidal cross section of the main body 1 so as to protrude outward from the main body 1 which is a cylindrical body. As described above, in this embodiment, the power supply circuit 5 is accommodated in the cylinder of the main body 1. Since the power supply circuit 5 includes an AC-DC conversion circuit, it generates heat. This heat generation is radiated to the outside through the fins 13a and 13b formed on the side plate 1b and the bottom plate 1c of the main body 1, thereby thermally protecting the power supply circuit 5. The power supply circuit 5 is mounted on the upper surface of the circuit board 14. Since the bottom plate 1c of the main body 1 faces the plate surface of the circuit board 14, the amount of heat received from the power supply circuit 5 is large. On the other hand, since the side plate 1b of the main body 1 is located on the side of the circuit board 14, the amount of heat received from the power supply circuit 5 is small. Therefore, in this embodiment, the density of the bottom plate side fins 13b formed on the bottom plate 1c of the main body 1 is increased (decreasing the pitch) to promote heat dissipation, and the density of the side plate side fins 13a formed on the side plate 1b is decreased (pitch). To make it lighter. Further, the fins can be shortened by increasing the density of the bottom plate-side fins 13b, thereby contributing to reducing the thickness of the entire lamp (the vertical height in the figure).

  The cover 2 is made of, for example, a translucent resin such as polycarbonate, and has a long plate-like top plate 2a, a curved plate 2b continuous from both sides of the top plate 2a in the body width direction, and both curved plates 2b. And a claw portion 9 formed so as to protrude inward from the lower end portion of the main body in the body width direction. Since the cover 2 has a flat dome shape that covers the support plate 1 a side of the main body 1, the length and width are the same as or substantially the same as those of the main body 1. Since the cover 2 is made of a translucent resin, when the LED substrate 3 emits light inside, the light leaks toward the outside and constitutes the LED module. When the cover 2 is put on the support plate 1 a side of the main body 1, as described above, the claw portion 9 of the cover 2 slides on the slope of the main body side claw portion 11 of the presser portion 8, and the engagement portion 10 and the main body 1 are moved. The claw portion 9 of the cover 2 presses against the inner surface of the engaging portion 10 in the width direction of the main body, and the main body 1 and the cover 2 are engaged. At this time, since the claw portion 9 of the cover 2 is caught by the main body side claw portion 11 of the presser portion 8, the engagement between the main body 1 and the cover 2 is not easily released. As can be seen from the above description, the compact fluorescent LED lamp of this embodiment is often used with the cover 2 facing downward, but it is easy to understand the assembly process described below. In order to do this, the description will be made with the cover 2 facing upward.

  As clearly shown in FIG. 11, a large number of LED elements 3a are arranged on the upper surface of the LED substrate 3, and the electrodes of the LED elements 3a are connected in series via a copper foil (not shown). Extending to one end, a bipolar LED substrate electrode 3b is formed at the end. The two-pole LED board electrode 3 b is connected to the LED board-side connector 16 via the wiring member 15. Further, as described above, the power supply circuit 5 is mounted on the upper surface of the circuit board 14. The power supply circuit 5 is formed in an elongated shape so as to be housed in the cylinder of the main body 1. However, the power supply circuit 5 of this embodiment is shorter than the main body 1, the cover 2, or the LED substrate 3. The LED board connection power supply circuit side connector 17 connected to the LED board 3 is provided near one end in the longitudinal direction of the circuit board 14 of the power supply circuit 5, and the other end in the longitudinal direction is provided at the other end. A connection pin connection power supply circuit side connector 18 connected to the connection pin 20 of the socket side cap 7 is provided. The power supply circuit 5 is housed in the cylinder of the main body 1 in a state of being inserted and covered in the insulating coating 4 bent into a rectangular parallelepiped shape. Further, a notch 26 is formed at one end in the longitudinal direction of the circuit board 14 of the power supply circuit 5 so as to cut the board in the width direction.

  The power supply circuit 5 is accommodated in the cylinder of the main body 1 in a state where it is covered with the insulating coating 4, specifically, inserted into the insulating coating 4 that is bent into an elongated rectangular parallelepiped shape. The insulating coating 4 is in the form of a single sheet. For example, the insulating coating 4 is bent four times in the same direction so that the sheet-shaped insulating coating 4 is wound, and the bent ends overlap with each other. It is formed in a square cross section that covers the surroundings. The power supply circuit 5 is insulated by inserting the power supply circuit 5 into the rectangular cylinder of the insulating coating 4 thus formed. The bent ends of the insulating coating 4 may be joined together, or an adhesive tape or the like may be wound around the insulating coating 4 having a square cross section.

  FIG. 6 is a perspective view showing the inside of the end-side cap 6, and FIG. 7 is a perspective view showing the outside of the end-side cap 6. The end-side cap 6 is, for example, a resin lid member that covers one end in the longitudinal direction of the main body 1 covered with the cover 2 together with the cover 2. And the edge part 6a which covers the outer peripheral surface of the main body 1 is formed. Further, screw end holes 22 are formed at positions corresponding to the screw grooves 12 of the main body 1 at both ends of the end-side cap 6 in the main body width direction. Also, a fixing claw 23 formed on both sides of the main body width direction on the bottom side of the main body 1 and a lower center portion in the main body width direction are formed below the end cap 6 in the figure, that is, on the bottom plate 1c side of the main body 1. The engagement fixing claws 24 are arranged in a staggered manner (not shown in FIG. 4), and among these, the engagement fixing claws 24 at the center in the width direction of the main body have an engagement convex portion upward in the figure. 25 is formed.

  As described above, the notch 26 is formed at one end in the longitudinal direction of the circuit board 14 of the power supply circuit 5 so as to cut the board in the width direction. One end in the longitudinal direction of the circuit board 14 of the power supply circuit 5 is connected to the fixing claw 23 of the end-side cap 6 so that the opening faces the fixing claw 23 and the engagement fixing claw 24 in the body (substrate) width direction. And the height (position) between the engagement fixing claws 24. Thereafter, the circuit board 14 of the power supply circuit 5 is slid in the width direction of the main body (substrate) from the side having no notch 26, that is, from the opposite side of the opening to the opening side of the notch 26, thereby obtaining FIG. As shown, the engagement protrusion 25 of the engagement fixing claw 24 is fitted and engaged in the notch 26 of the circuit board 14, and the front and back surfaces of the circuit board 14 are engaged with the fixation claw 23 and the engagement fixation claw. The power supply circuit 5 and the end-side cap 6 are fixed by abutting 24 in opposite directions. That is, the fixing claw 23 and the engagement fixing claw 24 of the end side cap 6, the circuit board 14 of the power supply circuit 5, and the notch 26 constitute a power supply circuit fixing mechanism. The power supply circuit 5 and the end side cap 6 are preferably fixed after the LED board side connector 16 and the LED board connecting power supply circuit side connector 17 are connected, as will be described later.

  FIG. 9 is a perspective view showing the outside of the socket-side cap 7, and FIG. 10 is a perspective view showing the inside of the socket-side cap 7. The socket-side cap 7 is, for example, a resin lid member that covers the other end in the longitudinal direction of the main body 1 covered with the cover 2 together with the cover 2. An edge 7a is formed to cover the outer peripheral surfaces of the cover 2 and the main body 1. Further, a socket-corresponding portion 27 having a prescribed socket insertion shape is formed on the side opposite to the edge portion 7a of the cap body, and can be attached to a socket of an existing instrument body, for example. Further, screw through holes 22 are formed at positions corresponding to the screw grooves 12 of the main body 1 at both ends of the socket corresponding portion 27 in the main body width direction. Further, at the center of the socket corresponding portion 27 in the body width direction, the four pins 20 and 21 having the same shape as defined in JIS as described above protrude outwardly so that they are arranged at the four corners of the square. Among them, the upper left and lower right pins forming one diagonal of the square in FIG. 8 are resin (non-conductive) dummy pins 21, and the lower left and upper right pins forming the other diagonal. Is a metal (conductive) connection pin 20.

  The reason why the four pins 20 and 21 are connected to the base on one side is to preheat the two filaments of the compact fluorescent lamp on one side. When the power supply circuit 5 generates a single DC power for the LED substrate 3 as in this embodiment, the necessary AC power may be bipolar. Therefore, there are only two metal connection pins 20, and the remaining two pins are, for example, resin dummy pins 21 formed integrally with the resin socket-side cap 7. Only the connection pin 20 of the sexuality) is connected to AC power (AC external power) from one side cap. However, by projecting a total of four pins 20 and 21, the connection (insertion) with a prescribed socket is ensured, and the lamp after connection (after insertion) is also stabilized. A wiring member 15 is connected to each of the two metal connection pins 20, and ends of the wiring members 15 are connected to the connection pin side connector 19. As will be described later, the connection pin side connector 19 is connected to the connection pin connection power supply circuit side connector 18 of the power supply circuit 5, so that the connection pin 20 is connected to the power supply circuit 5 and connected to the power supply circuit 5. AC external power is supplied through the pin 20.

  When the compact fluorescent lamp of this embodiment is assembled, for example, as shown in FIG. 11, the connection pin side connector 19 connected to the socket side cap 7 is connected to the connection pin connection power supply circuit side connector 18 of the power supply circuit 5. As described above, the LED board 3 is inserted into the gap between the support plate 1a of the main body 1 and the presser 8 and the power supply circuit 5 covered with the insulating coating 4 is inserted into the cylinder of the main body 1 as described above. Then, the LED board side connector 16 and the LED board connecting power supply circuit side connector 17 are connected. In this state, as described above, one end portion in the longitudinal direction of the circuit board 14 of the power supply circuit 5 is disposed between the fixing claw 23 and the engagement fixing claw 24 of the end-side cap 6, and then the circuit of the power supply circuit 5. The power supply circuit 5 and the end-side cap 6 are fixed by sliding the substrate 14 in the body width direction. When the power supply circuit 5 and the end-side cap 6 are fixed in this way, the cover 2 is put on the main body 1 and fixed, and the end-side cap 6 is put on one end in the longitudinal direction of the cover 2 and the main body 1. A screw 28 is inserted into the screw through hole 22 of the cap body of the end-side cap 6, and is screwed into the screw groove 12 of the body 1 to be tightened. Thereby, the main body 1, the cover 2, and the end side cap 6 are fixed. Further, after the socket 2 cap 7 is put on the other end in the longitudinal direction of the cover 2 and the main body 1, a screw 28 is inserted into the screw through hole 22 of the socket corresponding portion 27 of the socket side cap 7. Screw into the groove 12 and tighten. Thereby, the main body 1, the cover 2, and the socket side cap 7 are fixed.

  None of the screw grooves 12 is formed with a female screw. In general, since the screw 28 is made of steel (steel alloy) and the main body 1 of this embodiment is made of aluminum alloy, if the inner diameter of the circular cross section of the screw groove 12 is appropriate, just screwing the screw 28, It is possible to tighten while forming a female screw like so-called self-tapping. Thereby, not only the labor for forming the female screw is omitted, but the main body 1 can be manufactured only by cutting a material formed into a necessary cross-sectional shape by, for example, extrusion molding into a specified dimension, and the yield is accordingly increased. The cost can be reduced such as improvement of the cost. However, in this case, aluminum alloy chips are generated from the main body 1 by self-tapping. In the compact fluorescent lamp of this embodiment, the power supply circuit 5 is simply covered with the insulating coating 4 having a square cross section in order to reduce the number of manufacturing steps and the cost. Intrusion should be avoided. In this embodiment, since the screw groove 12 is open to the outside of the main body 1, aluminum alloy chips during screw screwing do not enter the main body 1 as foreign matter. Of course, a self-tapping screw may be used as the screw.

  Further, in the compact fluorescent lamp type LED lamp of this embodiment, the circuit board 14 of the power supply circuit 5 is fixed to the end-side cap 6 so that the power supply circuit 5 is closer to the end-side cap 6, that is, opposite to the socket-side cap 7. It is arranged. The socket-side cap 7 is for fixing the power supply circuit 5 inside the socket-side cap 7 from various conditions such as the shape of the socket corresponding portion 27 and the arrangement of the connection pins 20 and the wiring material 15 connected to the connection pins 20. There is no gap for arranging the mechanism, that is, the power supply circuit fixing mechanism. In particular, since the wiring member 15 connected to the connection pin 20 is a wiring member for commercial power supply, the outer diameter of the wiring member is large, and the power supply circuit 5 is connected to the socket side cap 7 in order to secure a wiring space. Cannot be placed closer. Therefore, in this embodiment, the power supply circuit 5 is disposed near the end-side cap 6. As a result, interference between the wiring member 15 connected to the connection pin 20 and the power supply circuit 5 can be avoided, and the power supply circuit 5 and the LED substrate 3 can be easily connected on the end-side cap 6 side. The circuit 5 can be securely fixed to the end-side cap 6. Moreover, the power supply circuit 5 can be stably arranged in the cylinder of the main body 1, and the cooling performance of the power supply circuit 5 by the fins 13a and 13b of the main body 1 described above can be ensured.

  Thus, in the compact fluorescent lamp type LED lamp of this embodiment, the flat dome-shaped cover 2 is provided on one of the flat sides of the flat cylindrical main body 1 when used by connecting to the one-side base socket of the instrument main body. The LED substrate 3 is attached to the cover 2 side of the main body 1 and the power supply circuit 5 covered with the insulating coating 4 is housed in the cylinder of the main body 1. A socket-side cap 7 is provided with an end-side cap 6 attached to one end in the longitudinal direction of the main body 1 covered with the cover 2 and pins 20, 21 connected to the one-side base socket at the other end. Install. Then, the power supply circuit 5 disposed near the end-side cap 6 is fixed to the end-side cap 6 by a power supply circuit fixing mechanism. Thereby, the power supply circuit 5 and the LED board 3 can be easily connected on the end-side cap 6 side while avoiding interference between the wiring member 15 connected to the connection pin 20 of the socket-side cap 7 and the power supply circuit 5. Further, the power supply circuit 5 can be securely fixed to the end side cap 6.

Further, a fixing claw 23 and an engagement fixing claw 24 that are formed so as to protrude from the end-side cap 6 into the cylinder of the main body 1 and are arranged in a staggered manner to contact the front and back surfaces of the circuit board 14 of the power supply circuit 5; The power supply circuit 5 is formed at one end in the longitudinal direction of the circuit board 14 so as to cut out the circuit board 14 in the board width direction, and is engaged with an engagement convex portion 25 formed to protrude from the engagement fixing claw 24. A power supply circuit fixing mechanism is constituted by the notch portion 26 to be joined. Thereby, the power supply circuit 5 can be fixed to the end side cap 6 easily and reliably.
Further, one end in the longitudinal direction of the circuit board 14 is arranged so that the opening of the notch 26 of the circuit board 14 faces the fixing claw 23 and the engagement fixing claw 24 in the board width direction. After the circuit board 14 is slid in the board width direction from the opposite side of the opening part of the notch part 26 toward the opening side of the notch part 26 after being arranged at a position between the engagement fixing claws 24, the power supply circuit 5. Is fixed to the end-side cap 6. Thereby, the power supply circuit 5 can be fixed to the end side cap 6 easily and reliably.
