Description

  The present invention relates to an illuminating device, and more particularly to a bar-shaped illuminating device using a light emitting element as a light source.

  As a new illumination device that replaces a fluorescent lamp or the like, an illumination device that uses a light emitting element such as an LED (light emitting diode) as a light source has attracted attention. Such an illuminating device has advantages of small size, low power consumption, and long life compared to a fluorescent lamp or the like.

  Moreover, the bar-shaped illuminating device which uses LED as a light source is known as an example of the said illuminating device (for example, refer patent document 1 and 2).

  Patent Document 1 describes a bar-shaped illumination device in which LEDs are arranged in a dotted manner in the longitudinal direction, and a lens that refracts and enlarges light from the LED in the longitudinal direction is arranged in front of each LED. In this lighting device, the LEDs are individually installed in a bar-shaped case, and an illumination hole for taking out light is provided in a portion corresponding to the LED in the bar-shaped case. The lens is inserted into the illumination hole.

  Patent Document 2 describes an illuminating device in which an elongated plate-like substrate on which a plurality of LEDs are mounted is housed in a transparent cylindrical body, and both ends of the cylindrical body are closed with waterproof packing. In this illuminating device, an insertion groove into which the end of the plate-like substrate is inserted is provided in the waterproof packing, and the plate-like substrate is fixed in a certain direction by being inserted into the insertion groove.

  The lighting device of Patent Document 1 can easily obtain a long bar-shaped lighting device by having the above configuration. For this reason, when installing in a refrigerated showcase or a freezer showcase, even if the display shelf is wide, the length of the lighting device can be made to match the width of the display shelf. Thereby, the whole display shelf can be easily illuminated.

  However, the lighting device disclosed in Patent Document 1 has a disadvantage in that air containing moisture in the showcase enters the lighting device when installed in a refrigerated showcase or a frozen showcase. For this reason, dew condensation occurs inside the lighting device due to the invading air, thereby causing an electrical short circuit or the like. As a result, the lighting device is likely to break down, and there is a problem that reliability is lowered.

  On the other hand, since the lighting device of Patent Document 2 has a cylindrical body sealed with a waterproof packing, even if it is installed in a refrigerated showcase or a frozen showcase, the air containing moisture in the showcase is exposed to the lighting device. Intrusion into the inside can be suppressed.

  However, in Patent Document 2, since the length of the lighting device is determined by the length of the plate-like substrate, there is an inconvenience that it is difficult to make the length of the lighting device a certain length or more. Here, when mounting an LED on a plate-like substrate, it is generally mounted using a mounting device or the like, but there is a limit to the length of the substrate that can be handled by the mounting device. For this reason, when the width | variety of a display shelf is wide, there exists a problem that it is difficult to lengthen an illuminating device enough so that it may become the length match | combined with the width | variety of the display shelf.

  The translucent cover member 40 is made of, for example, an acrylic resin, and is formed in a cylindrical shape (tunnel shape) having a thickness t of about 1 mm by extrusion molding or the like.

  Here, in the present embodiment, the translucent cover member 40 has a substantially arched top 41 and a substantially flat bottom 42 as viewed in cross section. The arcuate portion of the substantially arcuate top 41 has a radius of curvature R of about 13 mm. Further, both side portions of the bottom portion 42 are bent upward at a predetermined angle θ1 (for example, about 10 ° to about 20 °). This makes it easy to change the illumination angle. Moreover, the center part of the bottom part 42 becomes the mounting part 42a in which the plate-shaped member 30 (elongate light source) is mounted.

The pair of first convex portions 43 are arranged at a predetermined interval from each other, and the plate-like member 30 is slid and inserted between the pair of first convex portions 43. Thereby, when the plate-shaped member 30 (elongate light source) is slid and inserted into the translucent cover member 40, the displacement of the plate-shaped member 30 in the B direction is restricted. In addition, a pair of second convex portions 44 projecting from the diagonally upper side of the plate-like member 30 to the plate-like member 30 side is formed on the top portion 41 of the translucent cover member 40. The second protrusion 44 protrudes toward the plate member 30 with a predetermined angle θ2 (for example, about 45 °) with respect to the upper surface of the plate member 30. And the front-end | tip part 44a of the 2nd convex part 44 is formed so that the upper surface of the plate-shaped member 30 may be in contact with the outer side of the mounting substrate 20. FIG.

A reflection frame 12 is attached. The inside of the reflection frame 12 is filled with a sealing resin 13 (see FIG. 9) for sealing the light emitting diode element 11. The light emitting diode element 11 is a light emitting diode element that emits blue light, and the sealing resin 13 contains a phosphor (not shown) that converts the wavelength of the blue light. Thereby, the surface-mounted LED 10 is configured to emit white light. The light emitting diode element 11 is an example of the “light emitting element” in the present invention.

  The cap member 50 is made of rubber, for example, and is attached to both ends of the translucent cover member 40 to seal (air-tightly seal) the inside of the translucent cover member 40 as shown in FIG. Moreover, as shown in FIGS. 10-12, the cap member 50 with which one end of the translucent cover member 40 is attached is formed with two insertion holes 51 (see FIG. 11) through which the power harness 1 is inserted. Has been. The conductor on the anode side of the power harness 1 is inserted into one of the insertion holes 51, and the conductor on the cathode side of the power harness 1 is inserted into the other. Thereby, compared with the case where two conducting wires are inserted into one hole, the airtightness in the translucent cover member 40 can be easily maintained. The translucent cover member 40 is filled with a non-volatile gas such as nitrogen or argon, for example.

  The cap member 50 through which the power harness 1 is inserted is formed with a notch 52 for allowing the power harness 1 to escape. Thereby, since it becomes possible to fix the end surface of an illuminating device in contact with the wall surface 250 etc., the attachment freedom degree of an illuminating device can also be improved.

  In addition, it is preferable that the plate-shaped member 30 before the mounting substrate 20 is fixed is in a state where a plurality of (for example, five) members are connected as shown in FIGS. 13 and 14. If comprised in this way, the mounting board | substrate 20 can be fixed on the plate-shaped member 30 collectively. And after that, the connection part 32 is cut | disconnected with a nipper etc., for example, the plate-shaped member 30 is isolate | separated separately, and the workability | operativity of the operation | work which fixes the mounting substrate 20 on the plate-shaped member 30 is significantly improved. It becomes possible to improve. Further, in the vicinity of the connecting portion 32, a gap portion 33 into which a cutting edge such as a nipper is inserted is formed. The plate-like members 30 connected in this way can be formed by, for example, pressing or laser processing.

  In the lighting device according to the embodiment configured as described above, a constant voltage is supplied to the mounting substrate 20 from an external constant voltage source (not shown) via the power harness 1. Then, the current value is adjusted by the resistance element 60 mounted on the mounting substrate 20, and the surface-mounted LED 10 is driven with a constant current. Further, a part of the light emitted from the surface-mounted LED 10 is reflected by the inclined surface 44b (see FIG. 8) of the second convex portion 44.

  Moreover, the illuminating device by one Embodiment is used suitably as illuminating devices, such as a refrigerated showcase or a freezer showcase installed in a supermarket, a convenience store, etc., for example.

Since the plurality of mounting boards 20 can be connected by electrically connecting the LEDs 10 to each other, the length of the lighting device can be reduced by slidingly inserting the connected mounting boards 20 into the translucent cover member 40. Can be long enough. As a result, when the lighting device is installed in a refrigerated showcase or a frozen showcase, the length of the lighting device can be easily adjusted to the length of the display shelf even if the display shelf is wide. it can. Further, since the mounting board 20 is fixed on the long plate-like member 30, when the slide board is inserted into the cylindrical translucent cover member 40, the connecting portion of the mounting board 20 (the jumper wire 70) It is possible to suppress the load from being applied to the solder joint portion. Thereby, since it can suppress that the electrical connection of surface mount type LED10 is interrupted, it can suppress that reliability falls.

As a result, it is possible to suppress the occurrence of dew condensation in the interior, and therefore, it is possible to suppress the occurrence of migration, a short circuit of the circuit, and the like. As a result, a highly reliable lighting device can be obtained. Moreover, it can suppress that frost and cloudiness generate | occur | produce on the inner surface of the translucent cover member 40 by suppressing that the air containing a water | moisture content penetrate | invades in an illuminating device. Thereby, it is also possible to suppress the deterioration of characteristics such as a decrease in the amount of light.

  Moreover, in this embodiment, while forming the 1st convex part 43 which controls the position shift of the plate-shaped member 30 to a B direction in the bottom part 42 of the translucent cover member 40, the top part of the translucent cover member 40 is formed. 41 is formed with a second convex portion 44 for restricting the positional displacement of the plate-like member 30 (long light source) upward, so that the plate-like member 30 (long-shaped member) on which the mounting substrate 20 is mounted is formed. The light source) can be easily slid into the translucent cover member 40 without being displaced. For this reason, even when the length of the plate-like member 30 becomes sufficiently long by connecting a plurality of mounting substrates 20, the plate-like member 30 (long light source) can be easily attached to the translucent cover member 40. Can be stored. Thereby, the illuminating device which has sufficient length can be obtained easily.

Even when the wire 30 is bent, the load on the solder joint portion of the jumper wire 70 can be reduced by bending the jumper wire 70. For this reason, also by this, it can suppress that the electrical connection of surface mount type LED10 is interrupted | disconnected.

  Moreover, in this embodiment, the 2nd convex part 44 is formed so that it may protrude from the diagonally upper direction of the plate-shaped member 30 to the plate-shaped member 30 side, The slope 44b of the 2nd convex part 44 is surface mount type. It can function as a reflecting surface that reflects light from the LED 10 (light emitting diode element 11). Thereby, since generation | occurrence | production of illumination loss can be suppressed, in addition to being reliable and being able to make it sufficient length, the characteristic of an illuminating device can also be improved.

  Further, in the present embodiment, the width W2 in the B direction of the plate-like member 30 is made larger than the width W1 in the B direction of the mounting substrate 20 to thereby prevent the position deviation of the plate-like member 30 (first portion). It can suppress that the convex part 43 and the 2nd convex part 44) contact the mounting board | substrate 20. FIG. For this reason, when the plate-shaped member 30 is slid and inserted, a load is applied to the mounting substrate 20 due to the convex portions (the first convex portion 43 and the second convex portion 44) coming into contact with the mounting substrate 20. It is possible to suppress the occurrence of the inconvenience. Thereby, since it can suppress that the electrical connection of surface mount type LED10 is interrupted easily, it can suppress that reliability falls easily.
