  In addition, for example, a resin having transparency is adopted as the resin constituting the base portion, and a large number of light emitting elements and bending shape retaining members are completely embedded and disposed in the base portion made of the transparent resin. Then, it is possible to easily design the base portion to have a flat (innocent) shape without irregularities while having a large number of light emitting elements.

  In the invention described in claim 7, since the light emitting element employs a light emitting element with low heat generation such as an LED or an organic EL (the illumination efficiency is high and the heat generation during light emission is small). Even when the base portion on which this light emitting element is provided is made of resin, there is almost no fear of damage or deterioration of the base portion due to heat generation of each light emitting element, and it is possible to provide a large number of light emitting elements in a dense state. It becomes an illumination device with even more practicality.

  An embodiment of the present invention that is considered to be suitable (how to implement the invention) will be briefly described with reference to the drawings, showing the operation of the present invention.

  The present invention is an illuminating device that illuminates light to an illuminated portion a by irradiating light from a large number of light emitting elements 2 provided on a base portion 1.

  The base portion 1 has flexibility, and the base portion 1 can be bent and deformed into a predetermined shape by grasping a desired portion with a hand.

  Here, since the base portion 1 has shape retention, even if the hand is released from the base portion 1, the base portion 1 does not return and return to the state before being deformed. The base portion 1 remains in a predetermined shape that is bent and deformed.

  That is, the base portion 1 can be easily variably adjusted to a desired bent shape by hand.

  In addition, by variably adjusting the shape of the base portion 1 in this way, naturally, the orientations of the multiple light emitting elements 2 provided on the base portion 1 are also variable.

  Therefore, according to the present invention, the base portion 1 can be easily variably adjusted to a desired bending shape by hand, and thereby the light directivity of the light emitting element 2 is variably adjusted. The illumination range of light with respect to the illuminated part a can be adjusted.

  Further, for example, the base portion 1 is formed by resin-molding so that the bending shape-retaining member 3 is embedded in the resin 4, or the resin 4 is resin-molded into a cylindrical shape having a gap inside. In the case where the bending shape retaining member 3 is inserted and disposed in the internal space of the cylindrical resin 4, the base portion 1 can be easily molded with the resin 4 and can be easily manufactured. At the same time, the resin-made base portion 1 is integrally molded with a resin so that the flexible shape-retaining member 3 is embedded, or the base portion 1 is resin-molded into a cylindrical shape so that the flexible shape-retaining member 3 is By the simple manufacturing process of inserting and arranging in the internal space of the cylinder, the configuration of the base portion 1 having both flexibility and shape retention as described above can be easily achieved, making it easy to manufacture and improving mass productivity and cost. It will be even better.

  In particular, for example, the base portion 1 is resin-molded so that the plurality of light emitting elements 2 are embedded in the resin 4 constituting the base portion 1, and the plurality of light emitting elements 2 are made of the resin. When a large number of the base portions 1 are arranged, it is possible to simultaneously form the base portion 1 with resin and to provide a large number of the light-emitting elements 2 on the base portion 1. Further, for example, if the light-emitting element 2 has a configuration in which the above-described bending shape retaining member 3 is completely embedded in the resin base portion 1, the base portion 1 is flat (innocent). ) It can be designed and manufactured in a shape, and it is possible to realize a clean and high design. Furthermore, if the light emitting element is connected to a conductive part such as a conductive wire and emits light when energized, this light emission Elements, connected conductive parts, etc. Since the structure can protect the electrically insulated by the resin 4 constituting the base portion 1, a structure was also Xiu in terms of just not insulating protection improvement in design.

  At this time, if the light emitting element 2 having a low heat generation property such as an LED or an organic EL is adopted as the light emitting element 2, the resin-made base portion 1 may be damaged or heated by the heat generated when the light emitting element 2 emits light. There is no fear of deformation, and it is possible to provide a structure in which many light emitting elements 2 are provided in a dense state.

  Further, for example, the light emitting element 2 is configured to emit light from the light emitting part 2 a by energization from the conductive part 5 connected to the connection part 2 b of the light emitting element 2, and the conductive part 5 is integrated with the base part 1. When a flexible printed circuit board or a conducting wire having flexibility that can be bent and deformed is adopted, a general light emitting element 2 such as an incandescent lamp or LED that emits light when energized can be used, and the present invention can be designed and realized more easily. In addition, since a flexible printed circuit board (FPC) or a conductive wire having flexibility is adopted as the conductive portion 5 for energizing the light emitting element 2 that emits light by such energization, the base portion 1 is flexibly deformed. Correspondingly, the conductive portion 5 can be flexed and deformed well, and thus the present invention capable of exhibiting the excellent effects as described above can be surely realized.

  Further, in particular, a conductive wire is employed as the conductive portion 5, and the base portion 1 is configured so that the conductive portion is arranged in a spiral or meandering manner in a flexible portion that can be bent and deformed. When the conductive portion 5 is configured to be able to prevent the tensile force from being applied to the conductive wire or the light emitting element 2 connected to the conductive wire when the conductive wire 5 is bent and deformed, the conductive portion 5 is Even if the base body portion 1 is bent and deformed in any direction because of the conductive wire, not only can the lead wire cope well with this bending, but even if the base body portion 1 is bent and deformed in this way, the conductive wire is spiral or meandering. Due to the wiring, an excessive pulling force is not applied to the lead wire and the light emitting element 2 connected thereto, and thus problems such as disconnection of the lead wire due to bending deformation of the base portion 1 and a positional deviation of the light emitting element 2 occur. The absence.

  The base portion 1 of the present invention has, for example, a large number of light emitting elements 2 arranged in the longitudinal direction of the base portion 1, and the multiple light emitting elements 2 lead the irradiated portion a along the longitudinal direction of the base portion 1. The base portion 1 is configured to be flexible so that at least a part of the base portion 1 can be bent and deformed in a direction in which the base portion 1 can be adjusted toward and away from the illuminated portion a. If the illuminating range of the line light with respect to the illuminated portion a can be adjusted by bending and deforming the base portion 1 to a predetermined shape, for example, as shown in FIGS. It becomes an illuminating device that can illuminate line light similar to a general stand-type lighting fixture that illuminates line light with a fluorescent lamp, and has a higher practical value as an illuminating device used as this type of stand lighting fixture, for example. Become.

  Specific embodiments of the present invention will be described with reference to the drawings.

  In the present embodiment, a large number of light emitting elements 2 for irradiating light are provided on the base portion 1 and the illuminated portion a is illuminated by the large number of light emitting elements 2, and the base portion 1 bends a desired part by hand. It is configured by a member having flexibility that can be deformed, and having shape retaining properties that retains the shape in the predetermined shape without returning and returning when bent into a predetermined shape. A flexible shape-retaining member 3 having a shape-retaining property is provided along the base portion 1 so that the flexible shape-retaining member 3 and the base portion 1 are integrally bent and deformed and retained in shape. Illuminating device configured to be capable of adjusting the light directivity of the light emitting element 2 provided on the base unit 1 and adjusting the light illuminating range with respect to the illuminated part a by bending and deforming 1 into a predetermined shape. It is.

  Each part will be specifically described.

  The illumination device of the present embodiment can be used, for example, in a fixed lighting fixture for a wall that is used in a protruding state on a room wall or the like via a support member. It is portable and is configured to be used as, for example, a desk lamp for a desk by being placed on a desk.

  Specifically, as shown in FIG. 1, the apparatus main body 6 is installed on a predetermined installation surface, this installation surface is used as an illuminated part a, and the installation surface is formed by a large number of light emitting elements 2 of the base unit 1. The apparatus main body 6 installed on the installation surface is configured to be illuminated, and a support leg 7 is erected, and the base 1 is installed on the installation surface (the apparatus main body 6 by the support leg 7). It is a configuration in which it is supported and arranged in a floating state with respect to the illuminated part a).

  As shown in FIGS. 4 and 5, the base body portion 1 of the present embodiment is configured by resin molding so that the bending shape retaining member 3 is embedded in the resin 4.

  The shape-retaining member 3 employs a flexible tube, a metal wire, etc., and can be flexibly deformed in any direction at 360 ° C. by hand at a desired site, and then returned and returned. A rod-like member having a shape retaining property that does not cause deformation and having a total length substantially equal to the total length of the base portion 1 that is resin-molded into a rod shape (at least from the vicinity of one end in the longitudinal direction of the base portion 1 to the vicinity of the other end). Accordingly, the base portion 1 formed by resin molding by embedding and arranging the shape-retaining member 3 is also configured to have such flexibility and shape-retaining property. It is what.

  Further, as in another example of the present embodiment (see FIG. 8) to be described later, the base portion 1 is resin-molded into a cylindrical shape having a gap inside the resin 4 and the cylinder internal gap of the cylindrical resin 4 is formed. Further, the bent shape retaining member 3 may be inserted and disposed, or the base portion 1 itself may be composed of a member having flexibility and shape retaining properties. Any structure that can exhibit the same function as the base body 1 may be used.

  In addition, the base portion 1 is resin-molded so that the plurality of light emitting elements 2 are embedded in the resin 4 constituting the base portion 1, and the plurality of light emitting elements 2 are made of the resin base portion. 1 is arranged in a large number.

  More specifically, as shown in FIGS. 4 and 5, the base portion 1 has a large number of light-emitting elements 2 and bending shape-retaining members 3 projecting outward from the base portion 1 formed of the resin 4. The resin 4 is integrally molded with the resin 4 so as to be completely embedded and disposed in the base portion 1 without doing so.

  Thereby, the base | substrate part 1 is comprised in the solid rod shape without an unevenness | corrugation, as shown in FIG. 1, and is set as the refreshing external appearance. In the case where the light emitting portion 2a of the light emitting element 2 is embedded and disposed outside the resin base portion 1 as in another example of the present embodiment (see FIG. 8) described later. In this embodiment, as shown in FIGS. 4 and 5, the light emitting element 2 is completely embedded in the base portion 1. Therefore, a transparent or translucent resin 4 having translucency is adopted as the resin constituting the base portion 1.

  Further, each light emitting element 2 has a base surface 1 on which the main body portion 6 is installed after the base body portion 1 is linearly deformed from the state of bending deformation shown in FIG. The orientation of each light emitting element 2 is set so that the light emitting part 2a (front end side) of each light emitting element 2 faces (below) the illuminated part a when placed in a floating state with respect to a) On the other hand, the shape-retaining member 3 is configured to be located on the side of the connecting portion 2b, which will be described later, on the base end side of the light emitting element 2 embedded and disposed in the base portion 1.

  Further, as described above, the base portion 1 has a rod-like shape, and a plurality of light emitting elements 2 are arranged in a line in a row in a longitudinal direction of the base portion 1 (embedded arrangement). However, the base portion 1 may be formed wide and the light-emitting elements 2 may be arranged (planarly arranged) in the base portion 2 in two or more rows.

  Further, as the light emitting element 2, the light emitting element 2 having high luminous efficiency and low heat generation such as LED and organic EL is employed. Specifically, in this embodiment, an LED is employed.

  Accordingly, the resin 4 of the base portion 1 made of resin is configured not to be deteriorated, damaged, or deformed by heat generated when the light emitting element 2 emits light.

  Therefore, as shown in FIGS. 4 and 5, the light emitting element 2 (LED) of the present embodiment has a light emitting part 2a by energization from the conductive part 5 connected to the connection part 2b (LED lead terminal) of the light emitting element 2. Is configured to emit light.

  The conductive portion 5 that supplies current to the light-emitting element 2 employs a flexible conductive wire that can be bent and deformed integrally with the base portion 1, but as in another example of this embodiment described later (see FIG. 7), It is good also as a structure which employ | adopts a flexible printed circuit board (FPC) as the electroconductive part 5. FIG.

  As shown in FIG. 4 and FIG. 5, the conducting wire serving as the conductive portion 5 for energizing the light emitting element 2 is spirally formed on the flexible portion of the base portion 1. The wiring is arranged in a meandering manner.

  Accordingly, since the conductive wire is arranged in a meandering or spiral manner, even if the base body portion 1 is bent and deformed, the conductive wire is prevented from becoming a tension state, and the conductive wire and the conductive wire are connected thereto. Applying a tensile force to each light emitting element 2 is suppressed. As a result, for example, as shown in FIG. 1, the base portion 1 is bent and deformed in a direction in which it is in contact with or separated from the illuminated portion a (opposite direction to the illuminated portion a). As described above, even when the base body portion 1 is bent and deformed in any direction, for example, it is bent and deformed in a direction perpendicular to the direction facing the illuminated portion a (bently deformed in a U shape in the lateral direction). It is possible to cope with this, so that the disconnection of the conducting wire and the positional deviation of the light emitting element 2 cannot occur.

  As shown in FIGS. 4 and 5, the conductive portion 5 (conductive wire) is also embedded in the resin 4 of the resin base portion 1 in the same manner as the light emitting element 2 and the bending shape retaining member 3. Accordingly, each light emitting element 2 and the conductive portion 5 connected to the light emitting element 2 can be electrically protected (insulated) by the resin 4 constituting the base portion 1.

  In the present embodiment, the base portion 1 configured as described above is connected to the upper end portion of the support leg 7 erected on the main body portion 6 as shown in FIG.

  Specifically, it is configured such that the longitudinal end of the rod-like base body 1 is fitted and connected to the upper end of the support leg 7. The conductive portion 5 connected to each light emitting element 2 of the base portion 1, that is, a conductive wire is wired from the longitudinal direction end side of the base portion 1 to the inside of the support leg 7. The main body 6 is wired into the main body 6 and is supplied with electricity through a connection cord 8 provided in the main body 6.

  In addition to the configuration of the present embodiment illustrated in FIG. 1, for example, as illustrated in FIG. 3, the center portion in the longitudinal direction of the base portion 1 is formed in a T shape on the upper end portion of the support leg 7 of the main body portion 6. It is good also as a structure provided in a row. In this case, as shown in FIG. 3, it is possible to freely bend and deform both ends of the base portion 5 in the longitudinal direction.

  Reference numeral 9 in the drawing of the present embodiment denotes an operation unit 9 that switches between the illumination state and the illumination stop state of each light emitting element 2 of the base unit 1.

  Since the present embodiment is configured as described above, as shown in FIG. 1, the base portion is applied to the illuminated portion a by irradiation with light from each of the light emitting elements 2 arranged in the longitudinal direction of the base portion 1. The line light along the longitudinal direction of 1 can be illuminated.

  In addition, by deflecting and deforming a desired portion of the base portion 1 by hand and variably adjusting the shape of the base portion 1, the light directivity of each light-emitting element 2 corresponding to the bent and deformed portion is variably adjusted. It is possible.

  Therefore, in the present embodiment, as shown in FIGS. 1 and 3, for example, the base portion 1 is irradiated and deformed by bending and deforming so that the longitudinal end of the base portion 1 bends downward (in an umbrella shape). The line light can be condensed to the central portion in the longitudinal direction, and the light can be illuminated more spotwise. On the contrary, the base portion 1 is bent and deformed so that the longitudinal end side thereof is inclined upward (in a reverse umbrella shape). Then, the light from each light emitting element 2 can be scattered in the longitudinal direction, and can be further bent and deformed laterally along the illuminated portion a as shown in FIG. The range can be easily adjusted to a desired range simply by a simple operation only by adjusting the shape of the base body 1.

  6 to 8 show other examples of the base body portion 1 of the present embodiment described so far.

  More specifically, in another example shown in FIG. 6, the position of the bending shape retaining member 3 embedded in the resin-molded base part 1 is a rod-shaped base as compared with the present embodiment shown in FIG. 4. The case where it sets to the axial center position vicinity of the part 1 is shown.

  Further, another example shown in FIG. 7 shows a case where a flexible printed circuit board is used instead of a conductive wire as the conductive portion 5 for energizing each light emitting element 2 (LED). The connection portion 2 b (lead terminal) is connected to the substrate which is the conductive portion 5, and each light emitting element 2 is mounted on the conductive portion 5. Further, when a flexible printed circuit board is employed as the conductive portion 5 in this manner, the thin plate-like conductive portion 5 has a limited bending direction in which the base portion 1 can be bent and deformed. Will be. Therefore, as shown in FIGS. 1 and 3, when the base portion 1 is placed in a floating state on the illuminated portion a, the plate surface of the thin plate-like conductive portion 5 is opposed to the illuminated portion a. By setting the mounting posture of the conductive portion 5, the base portion 1 can be bent and deformed in a bending direction in which the line light illuminated from the base portion 1 can be condensed or scattered in the longitudinal direction as illustrated. .

  Further, another example shown in FIG. 8 shows a case where the base portion 1 is not formed into a rod shape as shown in FIG. 4 but is molded into a hollow cylinder having a gap portion. A large number of light emitting elements 2 are provided on the cylindrical base portion 1 so that the position portion (light emitting portion 2a) of the light emitting element 2 is embedded and fixed on the cylindrical peripheral surface of the cylindrical base portion 1. . Further, after the cylindrical base portion 1 is resin-molded, the rod-shaped bending shape retaining member 3 is inserted and disposed in the hollow portion (cylinder internal gap) of the base portion 1. In the case of the other example shown in FIG. 8, the light emitting portion 2a of each light emitting element 2 is embedded in the base portion 1 so as to protrude outward from the base portion 1. Even if the resin 4 constituting the portion 1 is not transparent, the light from the light emitting element 2 can be illuminated from the base portion 1 to the outside (the illuminated portion a) without any problem.

  The present invention is not limited to the present embodiment, and the specific configuration of each component can be designed as appropriate.
