Description

  The present invention relates to an illumination device in which a long substrate on which an LED element is mounted is accommodated in a cylindrical translucent case and a vending machine using the illumination device.

  Conventionally, fluorescent lamps have generally been used as lighting devices, but in recent years, lighting devices using LED elements that are excellent in low power consumption and low heat generation and have a long service life have been adopted. For example, lighting apparatuses using LED elements instead of fluorescent lamps have been used in vending machines and showcases.

  For example, Patent Document 1 states that “an end cap assembly for a semiconductor lighting tube having a circuit board on which a semiconductor lighting device is mounted and a lens covering the circuit board, which is configured to engage with the lens. An end cap body having a lens engaging surface and an external mating interface configured to mate with a socket connector of a fixture, and an end cap connector extending from the end cap body, electrically connected to the circuit board A first fitting portion configured to be configured, and an end cap connector holding a contact having a second fitting portion configured to be electrically connected to the socket connector. In Patent Document 1, a rail is provided that extends along the length of the lens and holds the circuit board at a predetermined position inside the lens. Therefore, the circuit board is held in the lens by the rail formed on the inner wall surface of the lens and the end cap connector.

  The tubular lens in Patent Document 1 described above is formed of a transparent or translucent extruded plastic part so that light is emitted through the lens. However, in the configuration of Patent Document 1, since it is necessary to form a rail by forming a recess in the inner wall surface of a lens having a substantially circular cross section, the shape of the tubular lens itself is complicated, The mold for forming the lens is complicated and it is difficult to remove the mold.

  Further, when a lighting device is configured by housing a circuit board on which LED elements are mounted in a plurality of tubular lenses, the wiring connecting the substrates is connected to a rail provided on the inner wall surface of the tubular lens. There is a problem that gets caught. In this case, not only the assembling workability is deteriorated but also an excessive force is applied to the wiring connecting the substrates, which causes disconnection.

  Furthermore, since the configuration of the rail in Patent Document 1 holds the circuit board inserted and held in a concave portion protruding from the inner wall surface of the tubular lens, the rail that holds the circuit board is an LED on the circuit board. It will be located in the light irradiation side rather than the surface in which the element was mounted. In general, since the irradiation angle range of the chip-type LED element is 170 °, the rail that holds the circuit board enters the irradiation range of light and a shadow is generated. Therefore, there is a problem that shadows are also reflected in the display article to be illuminated, and lighting with a high production effect cannot be performed.

  From the above, from the market, in a lighting device comprising a circuit board in which an LED element is mounted in a translucent tubular member, it is possible to avoid useless shadows and to facilitate assembly work. Development of devices has been desired.

  Therefore, as a result of earnest research, the inventors of the present invention avoided useless shadows in an illuminating device that accommodates a circuit board in which an LED element is mounted in a translucent tubular case, and performs assembly work. Has led to the provision of a lighting device and a vending machine equipped with the same.

Each lighting device illuminates a product sample in the product sample room.

  According to the illuminating device of the present invention, the cylindrical translucent case that accommodates the long substrate on which the LED element is mounted has a projecting reinforcing rib that improves its own strength. Since it is formed along the longitudinal direction on the outer surface, it is easier to manufacture as compared with the case where it is formed on the inner surface. Further, since it is not necessary to form a protrusion or the like on the inner surface of the translucent case, it is easy to incorporate the substrate to which the wiring is connected into the translucent case.

  In particular, the illumination device of the present invention is arranged to dispose the light irradiation side surface on which the LED element of the long substrate is mounted on the light irradiation side from the position of the protruding reinforcing rib. The disadvantage that the irradiated light is blocked by the reinforcing ribs of the translucent case can be avoided. Therefore, it is possible to avoid useless entry of shadows by the reinforcing rib formed in the translucent case, and to perform illumination with a high effect.

The translucent case 20 in the present embodiment is configured by a cylindrical member having both ends opened. The translucent case 20 is made of, for example, a material that can transmit light emitted from the LED element 11 accommodated inside, such as acrylic resin or polycarbonate resin, to the outside. In addition, as long as it has translucency, you may comprise the translucent case 20 using materials other than the resin quoted here.

  Then, as shown in FIG. 2, the translucent case 20 in the present embodiment has a cross section cut in a direction orthogonal to the longitudinal direction of the translucent case 20 extending in the width direction of the long substrate 10. It has a flat and substantially elliptical shape. At this time, the inner diameter of the translucent case 20 is formed such that the dimension corresponding to the major axis of the elliptical cross section is the dimension that facilitates insertion and removal of the long substrate 10.

  And the outer surface of the said translucent case 20 is equipped with the projection-shaped reinforcement rib 21 along the longitudinal direction. In the present embodiment, the reinforcing rib 21 is opposed to the outer side surface on the side end surfaces 10B and 10B side extending in the longitudinal direction of the long substrate 10, that is, in this case, the outer surface at a position intersecting with the major axis of the ellipse.

<End mounting member>
Next, the end attachment member 30 that engages and holds the translucent case 20 that accommodates the long substrate 10 on which the LED element 11 is mounted inside the attachment device side will be described. The end attachment member 30 is made of a flexible material, and is attached to the end of the translucent case 20 so as to surround the outer periphery of the end of the translucent case 20. An attachment member main body 31 with a portion cut away is provided.

  Specifically, as shown in FIG. 4, the attachment member main body 31 is formed by cutting a part of a tube surrounding an outer periphery of an end cut in a direction orthogonal to the longitudinal direction of the translucent case. It has a letter shape. In the present embodiment, since the cross section of the translucent case 20 has a substantially elliptical shape as described above, the cross section of the mounting member main body 31 also has a substantially elliptical shape with a part cut away. ing.

  An engagement portion that engages and holds the translucent case 20 in an engagement hole such as a square hole formed in advance on the attachment device side is formed at the end portion 31A formed by cutting out the attachment member main body 31. 32 are formed.

In the present embodiment, the translucent case 20 is formed at positions that are shifted in the longitudinal direction. Thereby, the operativity of the said engaging parts 32 and 32 can be improved more.

  Further, on the inner peripheral surface of the attachment member main body 31, concave grooves 33 and 33 are formed for inserting and holding the reinforcing ribs 21 formed on the outer peripheral surface of the translucent case 20 that surrounds and holds the outer periphery of the cross section.

  The attachment member body 31 includes an end portion 10A of the long substrate 10 accommodated in the translucent case 20 to be attached, specifically, a longitudinal end portion 10A in which the above-described notch 13 is formed. A substrate holding part 34 for gripping is provided. In the present embodiment, the substrate holding part 34 includes an upright piece 34A extending from the end edge of the attachment member main body 31 toward the inside in the radial direction of the cross-sectional ellipse, and the longitudinal direction (transparent) of the attachment member main body 31 from the upright piece 34A. It is constituted by a pair of gripping pieces 34B and 34B extending inwardly in the longitudinal direction of the optical case 20. These gripping pieces 34B and 34B are preferably arranged apart from each other by a dimension that allows the end portion 10A of the long substrate 10 to be sandwiched and held without hindrance.

  In addition, the substrate holding portion 34 is configured so that the long substrate 10 accommodated in the translucent case 20 is attached to the long substrate 10 in a state in which the end attachment member 30 is attached to the translucent case 20. The light irradiation side surface 10 </ b> C on which the LED element 11 is mounted is held at a position that is closer to the light irradiation side than the reinforcing rib 21 formed in the translucent case 20.

  In the present embodiment, the long substrate in the translucent case 20 is provided by the substrate holding portion 34 provided with the standing piece 34A and the pair of gripping pieces 34B, 34B provided on the end attachment member 30. The position 10 is described above as “the surface 10C on the light irradiation side on which the LED element 11 of the long substrate 10 is mounted is on the light irradiation side with respect to the reinforcing rib 21 formed on the translucent case 20”. However, the present invention is not limited to this, so long as the long substrate 10 can be held at the specific position. The configuration may be adopted.

  With the above configuration, the assembly and attachment procedure of the lighting apparatus L of the present embodiment will be described. First, the long substrate 10 with the LED element 11 mounted is inserted into the translucent case 20 from the opened end. At this time, the side end surfaces 10 </ b> B and 10 </ b> B of the long substrate 10 are inserted into the translucent case 20 so as to face the inner surface of the flat portion 22 of the translucent case 20.

  Then, the end attachment members 30 and 30 are attached to both end portions 10A and 10A of the translucent case 20 in a state where the long substrate 10 is accommodated, respectively. Specifically, the end mounting member 30 is inserted from the end of the translucent case 20, and the translucent case is interposed between the gripping pieces 34 </ b> B and 34 </ b> B of the substrate holding unit 34 provided on the end mounting member 30. In the state where the end portion 10 </ b> A of the long substrate 10 within 20 is sandwiched, the upright piece 34 </ b> A of the substrate holding portion 34 is pushed in until it contacts the long substrate 10. At this time, the upright piece 34A of the substrate holding portion 34 enters the notch 13 formed in the end portion 10A of the long substrate 10 and the end portion 10A of the long substrate 10 is engaged and held by the substrate holding portion 34. The In the same manner, the end attaching member 30 is also attached to the end of the other translucent case 20.

  Thereafter, the engagement portions 32 of the end attachment members 30 and 30 are inserted into the engagement holes of the attachment device to be the attachment location of the lighting device L, and are engaged and held. Specifically, the end attachment member 30 is pressed and deformed in a direction in which the engagement portions 32 and 32 of the end attachment member 30 approach each other, and the engagement portions 32 and 32 are engaged on the attachment device side. After inserting into the hole, release the pressing force. Thereby, each engaging part 32 and 32 of the edge part attachment member 30 is engaged and hold | maintained in the engagement hole by the side of an attachment apparatus with the elastic force of edge part attachment member 30 itself. In addition, although the engagement hole of the attachment apparatus used as the attachment location of the illuminating device L is not shown in FIG. 5, the state which deform | transformed the edge part attachment member 30 and was hold | maintained at the engagement hole is shown.

  In a state where the end mounting member 30 is engaged and held in the engagement hole on the mounting device side, each of the concave grooves 33 and 33 of the end mounting member 30 is pressed toward the translucent case 20 and the concave groove Reinforcing ribs 21 formed on the translucent case 20 are inserted and held in 33, and inconvenience due to rattling can be avoided. Therefore, it is possible to realize illumination for a desired location, and it is possible to perform effective illumination.

  The long substrate 10 accommodated in the translucent case 20 in a state in which the lighting device L is attached to the attachment device is light in which the LED element 11 is mounted by the substrate holding portion 34 of the end attachment member 30. The surface 10C on the irradiation side is arranged in a state deviated to the light irradiation side so that it is closer to the light irradiation side than the reinforcing rib 21 formed on the flat portion 22 of the translucent case 20.

  Therefore, by arranging the light irradiation side surface 10C on which the LED elements 11 of the long substrate 10 are mounted on the light irradiation side relative to the position of the protruding reinforcing ribs 21 formed on the translucent case 20, The disadvantage that the light emitted from the LED element 11 is blocked by the reinforcing ribs 21 of the translucent case 20 can be avoided. Therefore, it is possible to avoid useless shadows by the reinforcing ribs 21 formed in the translucent case 20 and perform illumination with a high effect.

  Further, the lighting device L according to the present invention causes the reinforcing rib 21 of the translucent case 20 to be in the concave groove 33 of the end mounting member 30 by the pressing force generated by the engaging portion 32 being engaged and held on the mounting device side. Since the structure which hold | maintains inside and the elongate board | substrate 10 in the said translucent case 20 is pressed and held from the side end surface 10B side is employ | adopted, the translucent case which accommodates a elongate board | substrate like the past There is no need to form a groove-like rail that also serves as a reinforcement for itself to hold the long substrate. Therefore, when the translucent case 20 is made of a resin, extrusion is possible and the mold release property is good, so that the manufacture becomes easy. In addition, since the rail-shaped protrusion is not formed on the inner surface of the translucent case 20, it is easy to incorporate the long substrate 10 connected to the wiring into the translucent case 20.

  As another example of the substrate holding portion 34 described above, at least one of the gripping pieces 34B and 34B, for example, on the side opposite to the side where the engaging portion 32 is formed as shown in FIG. A protrusion 34C that protrudes toward the long substrate 10 inserted at the tip of the gripping piece 34B that is positioned may be provided. In this case, as shown in FIG. 7, an engagement hole 10D that can be detachably engaged with the projection 34C is formed on the long substrate 10 side. With the above configuration, when the end attachment member 30 is attached to the translucent case 20, the engagement hole 10 </ b> D formed in the long substrate 10 in the translucent case 20 is formed in the end attachment member 30. The protrusion 34C of the gripping piece 34B is engaged. Thus, the end portion of the long substrate 10 accommodated in the translucent case 20 is held by the end portion attaching member 30 in a state where the end portion attaching member 30 is attached to the translucent case 20. Therefore, the lighting device L can be carried in a stable state, and the attachment work to the attachment location can be performed.

  When the above-described configuration is employed, it is preferable that the gripping piece 34B on which the protrusion 34C is formed be formed longer than the other gripping piece 34B. As a result, the engagement between the engagement hole 10D of the long substrate 10 to be attached and the projection 34C can be easily performed.

  Next, as described above, a plurality of illumination modules in which a predetermined number of LED elements 11 are arranged on the long substrate 10 are accommodated in a single translucent case 20, and these are connected in series. The case where one illuminating device L is comprised is demonstrated with reference to drawings. In this case, as shown in FIG. 8, the translucent case 20 is formed with an opening 23 through which both end portions 10 </ b> A and 10 </ b> A of each of the long substrates 10 and 10 of adjacent lighting modules are exposed to the outside. .
