<Overall configuration of light emitting diode module device>
First, the configuration of a light emitting diode module device 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic configuration diagram of a light emitting diode module device 1 according to the present embodiment. FIG. 2 is a partially enlarged perspective view of the light emitting diode module device 1 of FIG.

  As a schematic configuration, a light-emitting diode module device 1 includes a flexible tube 2 that is a flexible rod-shaped body, and seven light-emitting devices provided on the surface of the flexible tube 2 along the extending direction of the flexible tube 2. 3 and the light emitting device 3 are electrically connected to each other or have a lead wire 4 for supplying electric power to the light emitting device 3 located at the end of the flexible tube 2. The light emitting diode module device 1 connects the flexible tube 2 to the fan 5 that supplies air into the flexible tube 2, the supply pipe 6 that serves as a passage for the air that is supplied from the fan 5 to the flexible tube 2, and the supply pipe 6. It has the connection member 7 for. Furthermore, the light emitting diode module device 1 has a connection for connecting the flexible tube 2 to various devices, members or fans 5 at the end opposite to the end of the flexible tube 2 to which the connection member 7 is attached. A member 8 is provided.

  Below, each member which comprises the light emitting diode module apparatus 1 is demonstrated in detail, and the operation | movement and effect of the light emitting diode module apparatus 1 are demonstrated.

(Flexible Tube)
In order to easily dissipate heat generated by the light emitting device 3, the flexible tube 2 in the present embodiment is made of a general metal such as copper, aluminum, iron, or stainless steel. Moreover, as shown in FIG.1 and FIG.2, the flexible tube 2 of a present Example is corrugated, and the whole shape is a wave shape that several ring bodies connected. With such a shape, the flexible tube 2 of the present embodiment can be bent in all directions intersecting the extending direction of the flexible tube 2, and the degree of bending and the degree of bending can be freely changed. Here, the omnidirection that intersects the extension direction refers to the direction of all line segments that cross the bending point when the flexible tube 2 is bent at a predetermined position. That is, the flexible tube 2 can be bent in all directions extending radially from the bending point.

  In other words, the flexible tube 2 can be bent in a direction that intersects the extending direction thereof and is different from the optical axis direction of the light emitting device 3. In this way, if the flexible tube 2 can be bent in a direction different from the optical axis direction of the light emitting device 3, the light emitted from the light emitting device 3 can be obtained even when the flexible tube 2 is bent along the shape of a shelf or the like. The object can be suitably irradiated. Therefore, even if the flexible tube 2 is not bendable in all directions intersecting with the extending direction, it can be bent only in a direction intersecting with the extending direction of the flexible tube 2 and different from the optical axis direction of the light emitting device 3. If it exists, the usability of the light emitting diode module apparatus 1 can be improved.

  In addition, the flexible tube 2 has a cavity 2a for circulating air therein, and has a hollow structure.

  The flexible tube 2 is not limited to bendable by being subjected to the corrugated process as described above. For example, the flexible tube 2 is formed by braiding a plurality of stainless steel wires so that all of the flexible tubes 2 intersect the extending direction. You may form the flexible tube 2 which can be bent in an azimuth | direction. In addition, the flexible tube 2 is not limited to a metal, and for example, a flexible material such as plastic, resin, rubber, vinyl, or the like is used, and the flexible tube 2 can be bent in all directions intersecting the extending direction. May be formed. If such a generally flexible material is used, the heat dissipation is reduced as compared with a metal material. However, special processing such as corrugation or wire braiding as described above is not necessary, and the cost is reduced. Can be reduced. Further, the outer diameter and inner diameter of the cut surface in the direction orthogonal to the extending direction are not limited to the circular shape as in the present embodiment. For example, the outer diameter of the cut surface is an elliptical or polygonal shape. A rectangular flexible tube may be used as a flexible rod-shaped body, and only the outer diameter is circular as in the present embodiment, and the inner diameter (that is, the cavity 2a) is a polygonal flexible tube, or only the inner diameter is A flexible tube having a circular shape and a polygonal outer diameter may be used as in the present embodiment. And when not supplying refrigerant | coolants, such as air, you may replace with the flexible tube 2, and replace with the solid-shaped rod-shaped body in which the cavity 2a is not formed like a present Example. Even in such a case, the rod-shaped body needs to have flexibility, but the outer diameter may be circular or polygonal.

  Since the flexible tube 2 is formed from the metal or non-metallic material described above, the flexible tube 2 can be cut at various positions. If it can be cut freely at such a predetermined position, the flexible tube 2 can be freely processed according to the width and shape of the installation place of the light emitting diode module device 1 and adapted to the installation place. In this state, the light emitting diode module device 1 can be easily attached.

(Light emitting device)
Next, the light emitting device 3 will be described in detail with reference to FIGS. Here, FIG. 3 is a schematic perspective view of the light emitting device 3 provided in the light emitting diode module device 1 according to the present embodiment.

  As can be seen from FIGS. 2 and 3, the light emitting device 3 includes a white LED 11 that is a light emitting element that emits white light, a circuit board 12 for mounting the white LED 11, a circuit board 12, and a flexible tube 2. An attachment 13 that functions as an engaging portion to be engaged is provided.

A green phosphor that converts the wavelength of purple light into green light, a red phosphor that converts the wavelength of purple light emitted from the purple LED chip into red light, a base material that holds these phosphors and covers the purple LED chip, and It is comprised from the package which accommodates these members. Therefore, the white LED 11 of this embodiment converts the wavelength of violet light emitted from the violet LED chip into blue light, green light, and red light by various phosphors, and these blue light, green light, and red light. The combined light is emitted as white light. Note that the wavelength conversion member that converts the wavelength of light from the LED chip and emits the desired light includes the above-described base material and various phosphors held by the base material.

  As a specific purple LED chip, for example, there is a GaN-based LED chip in which GaN or PSS is used as a substrate and an InGaN semiconductor is used for a light emitting layer. In this embodiment, the peak wavelength of light emitted from the LED chip 3 is preferably in the wavelength range of 400 nm to 420 nm, and more preferably in the wavelength range of 405 nm to 415 nm.

  In addition, as a specific base material, for example, various resins such as silicone resins, epoxy resins, and polycarbonate resins, or materials having translucency such as glass can be used.

  The circuit board 12 has a substantially rectangular parallelepiped shape, and is made of ceramics such as alumina (aluminum oxide). Further, wiring patterns 12 a and 12 b for mounting the white LED 11 and connecting the lead wire 4 are formed on the circuit board 12. The wiring patterns 12a and 12b are made of a metal material such as gold or copper, for example. The circuit board 12 is not limited to alumina, and may be a glass epoxy board, but is preferably a board that efficiently reflects without absorbing light emitted from the white LED 11.

  In the present embodiment, the external connection terminals (not shown) of the white LED 11 are electrically connected to the wiring patterns 12a and 12b via solder. Further, as shown in FIG. 2, the entire wiring patterns 12a and 12b are not in contact with the external connection terminals of the white LED 11, and part of the wiring patterns 12a and 12b are exposed, and lead wires are exposed to the exposed portions. 4 are connected, and adjacent white LEDs 11 (that is, the light emitting devices 3) are electrically connected to each other.

  The attachment 13 has a semi-circular or substantially U-shaped outer shape and is made of a metal such as aluminum, copper, or stainless steel. When the attachment 13 is made of metal, the heat generated by the light emission of the white LED 11 can be radiated to the flexible tube 2 through the attachment 13.

  Further, the inner diameter of the attachment 13 is slightly smaller than or the same as the maximum outer diameter of the flexible tube 2, and the flexible tube 2 and the attachment 13 are engaged with each other when the flexible tube 2 is sandwiched between the attachments 13. Has been made. That is, the attachment 13 is engaged so that the attachment 13 is not separated from the flexible tube 2 by a force that the attachment 13 tends to shrink inward.

  Although the attachment 13 does not come off the flexible tube 2 due to its own weight, the attachment 13 is engaged with the flexible tube 2 to the extent that it can slide on the surface of the flexible tube 2. That is, the attachment 13 is movable in the extending direction of the flexible tube 2 (direction of the bidirectional arrow A in FIG. 2) and is rotatable in the circumferential direction of the flexible tube 2 (direction of the bidirectional arrow B in FIG. 2). It is. Therefore, the light emitting device 3 according to the present embodiment is provided to be movable along the extending direction and the circumferential direction of the flexible tube 2. The light emitting device 3 does not have to be movable along the extending direction and the circumferential direction of the flexible tube 2, and may be movable in either the extending direction or the circumferential direction.

  As described above, the adjacent light emitting devices 3 are electrically connected by the lead wires 4. Further, one end of the light emitting device 3 positioned at both ends of the flexible tube 2 is connected to an external connection terminal (not shown) via a lead wire 4. Therefore, when a current is supplied from the external connection terminal to the light emitting device 3 located at either end of the flexible tube 2, the current is also supplied to the other light emitting devices 3 and attached to the flexible tube 2. All the light emitting devices 3 emit light simultaneously. Note that characteristics such as color temperature and chromaticity of white light emitted from the white LED 11 may be changed by adjusting the current supplied to the white LED 11. In addition, by adjusting the connection relationship of the light emitting devices 3, for example, adjacent light emitting devices 3 may emit light at different timings without causing all the light emitting devices 3 to emit light simultaneously. Further, the connection relationship of the light emitting devices 3 is controlled so that the chromaticity and color temperature of the light emitted from each light emitting device 3 can be controlled independently while causing the light emitting devices 3 attached to the flexible tube 2 to emit light independently. You may adjust.

  In the present embodiment, the light emitting device 3 is movable along the extending direction and the circumferential direction of the flexible tube 2, and the distance between the light emitting devices 3 can be freely adjusted. It is preferable to make it longer. In other words, the interval between the light emitting devices 3 can be adjusted within the range of the length of the lead wire 4, and the lead wire 4 is always longer than the interval between the adjacent light emitting devices 3.

(fan)
As shown in FIG. 1, the fan 5 has four wings 5 a and is attached to one end of the flexible tube 2 in the extending direction via a supply pipe 6 and a connection member 7. Here, the outside of the supply pipe 6 and the inside of the connection member 7 are threaded, and the supply pipe 6 and the connection member 7 are connected by screwing the connection member 7 into the supply pipe 6. Yes.

  The fan 5 supplies air, which is a refrigerant, to the cavity 2 a of the flexible tube 2 through the supply pipe 6 by rotating the blades 5 a. That is, when the fan 5 is driven and air is sequentially supplied into the flexible tube 2, it is possible to dissipate the heat accompanying the light emission of the white LED 11 satisfactorily. More specifically, the heat generated by the light emission of the white LED 11 is transmitted to the supplied air via the circuit board 12, the attachment 13, and the flexible tube 2, and the heated air is released to the outside of the flexible tube 2. By doing so, the heat accompanying the light emission of the white LED 11 is radiated well.

  In this embodiment, only one end of the flexible tube 2 is connected to the fan 5 via the connection member 7. However, the other end of the flexible tube 2 is connected to the fan 5 via the connection member 8, and the air May be circulated. In other words, air may be supplied from one end in the extending direction of the flexible tube 2, discharged from the other end, and circulated in the flexible tube 2. It is also preferable to install a mechanism and a region where air is cooled during circulation. At this time, an exhaust pipe is connected to the connection member 8, and air returns to the fan 5 through the exhaust pipe.

  In particular, the fan 5 is preferably a small blower or the like. The refrigerant supplied to the cavity 2a of the flexible tube 2 is not limited to air, and water, oil, cooling gas, or the like may be supplied. When supplying such a refrigerant, it is preferable to use a desired pump instead of the fan 5 and circulate the refrigerant.

  In the embodiment described above, the circuit board 12 is attached to the substantially central portion of the attachment 13. However, in the light emitting diode module device 1 ′ of the present modification, the circuit board 12 is attached to each of both ends of the attachment 13. Furthermore, LED chips 21 and 22 are mounted on the circuit board 12. Therefore, as shown in FIG. 5, the LED chips 21 and 22 provided in one attachment emit light in opposite directions.

  In this modification, the LED chip 21 is, for example, a blue LED chip that emits blue light, and the LED chip 22 is, for example, a red LED chip that emits red light.
