Description

  The present invention relates to a lighting stand.

  Conventionally, fluorescent lamps and incandescent lamps have been widely used as illumination light sources for lighting stands. However, fluorescent lamps and incandescent lamps that use an illumination light source consume a large amount of power and maintain a long service life. Further, it is difficult to reduce the weight because an inverter, a ballast, and the like are necessary as a lighting circuit.

  Therefore, in recent years, there has been an active movement to use LEDs as illumination light sources. For example, conventionally, a lighting stand having a lamp body in which a plurality of LEDs are linearly arranged on a wiring board and a structure in which the lamp body and a fixed base are connected by a flexible tube has been proposed. (For example, refer to Patent Document 1).

As another conventional technique, a chip LED is mounted on each of a plurality of circuit boards, the circuit boards are electrically connected to each other via a relay line, and the chip LED, the circuit board, and the relay line are transparent. The thing which coat | covered with the tube and comprised the light-emitting body unit is proposed (for example, refer patent document 2).

  However, although the illumination stand described in Patent Document 1 can change the light illumination direction to some extent by bending a flexible tube, it has a configuration in which a plurality of LEDs are linearly arranged on a wiring board. This is equivalent to replacing a linear fluorescent lamp. Therefore, its use is limited to a field such as a table lamp, and it is difficult to secure various uses.

  Moreover, since the thing of the structure described in patent document 2 has coat | covered several chip LED with the transparent tube, although the whole deformation | transformation is possible, if the external force is removed, the state after a deformation | transformation will be hold | maintained as it is. Cannot be used when it is necessary to illuminate a specific direction.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide an illumination stand that can illuminate an arbitrary direction as necessary and can secure various uses. .

  In order to achieve the above object, the lighting stand according to the first aspect of the present invention has a plastic arm portion erected from the pedestal portion, and a plurality of light emitting elements can be rotated in the circumferential direction on the arm portion. It is characterized by being sequentially arranged along the longitudinal direction in the state.

  According to a second aspect of the present invention, there is provided the lighting stand according to the first aspect of the invention, wherein the arm portion is a rigid pipe formed in a straight tube shape and a flexible pipe formed in a bellows shape or a coil shape. Both pipes are alternately and integrally joined in a state of being rotatable in the circumferential direction, the rigid pipe is provided with the light emitting element therein, and A light emission window is formed at a position facing the light emitting element.

  In the lighting stand according to the first aspect of the present invention, since the arm portion is plastic, it is easily deformed when an external force is applied to the arm portion, and the deformed state is maintained as it is even if the external force is removed. In addition, since the plurality of light emitting elements are arranged so as to be rotatable in the circumferential direction of the arm portion, the entire arm portion is bent and the rigid pipe is rotated so that all the light emitting elements face a specific direction. By doing so, it is possible to illuminate one direction intensively, and for example, it can be used as a table lamp. Further, if the rigid pipe is rotated with the arm portion standing upright so that each light emitting element faces various directions, it can be used for various purposes such as an intelligent lighting stand.

  According to the second aspect of the present invention, the arm portion is joined integrally and alternately with the rigid pipe and the flexible pipe being rotatable in the circumferential direction, and the light emitting element is disposed inside the rigid pipe. Therefore, the light emitting element can be rotated along the circumferential direction of the arm portion while ensuring the plasticity of the arm portion. In addition, since the light emitting elements and the wiring thereof are provided inside the arm portion, the electrical connection between the light emitting elements can be reliably performed without impairing the overall beauty.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing an entire illumination stand according to an embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view showing a portion indicated by symbol A in FIG. The lighting stand 1 of this embodiment includes a pedestal portion 2 and a plastic arm portion 3 erected from the pedestal portion 2.

  The pedestal 2 is provided with an on / off switch 4, a dimming switch 5, a power cable 6 and the like for blinking a light emitting element 10 described later. The arm portion 3 is formed by alternately joining a rigid pipe 7 made of a synthetic resin formed in a straight tube shape and a flexible pipe 8 made of a metal such as stainless steel formed in a bellows shape.

  That is, as shown in FIG. 2, the end of each rigid pipe 7 is expanded in inner diameter so that the end of the flexible pipe 8 is fitted. Therefore, the pipes 7 and 8 are fitted together. By doing so, both 7 and 8 are integrally joined in the state which can be rotated in the circumferential direction, respectively. In this embodiment, an accordion-shaped pipe is used as the flexible pipe 8, but it is also possible to use a flexible pipe 8 that is tightly wound in a coil shape. Moreover, the rigid pipe 7 can also use a metal thing.

  A light emitting element 10 and a circuit board 11 on which the light emitting element 10 is mounted are disposed inside each rigid pipe 7. Further, a light exit window 13 is formed at a position of the rigid pipe 7 facing the light emitting element 10, and the circuit boards 11 are electrically connected to each other via a relay line 14.

  As the light emitting element 10, for example, a white LED in which a blue LED and a yellow phosphor are combined, a multi-chip white LED in which R, G, B3 primary color LEDs are combined, or the like is applied.

  Since the lighting stand 1 having the above-described configuration uses a plurality of light emitting elements 10 as light sources, it consumes less power and has a long life while ensuring a required amount of light. Further, since the light emitting element 10 is disposed on the arm portion 3, the whole is slim and does not take up space.

  Further, since the arm portion 3 is configured by integrally joining the rigid pipe 7 and the flexible pipe 8 alternately, the plasticity of the arm portion 3 can be ensured. For this reason, it is easily deformed when an external force is applied to the arm portion 3, and the deformed state is maintained as it is even if the external force is removed. Further, since the light emitting element 10 is disposed inside the arm portion 3, the circuit boards 11 on which the light emitting elements 10 are mounted can be electrically connected via the relay line 14 without impairing the aesthetic appearance.

  Moreover, since the rigid pipe 7 and the flexible pipe 8 are joined so as to be rotatable in the circumferential direction, for example, as shown in FIG. 3, the arm portion 3 is bent into an L shape, and the rigid pipe 7 If the irradiation direction is aligned so that all the light emitting elements 10 face a specific direction by rotating the, the required direction can be intensively illuminated. For this reason, for example, it can be used as a table lamp.

  On the other hand, if the rigid pipe 7 is rotated in a state where the arm portion 3 is upright so that the light emitting elements 10 face in various directions, for example, as shown in FIG. it can. Moreover, if this lighting stand 1 is mounted on the floor surface, it can be used for interior lighting and can be used for various purposes.

  In this embodiment, the arm portion 3 is constructed by alternately joining the rigid pipes 7 and the flexible pipes 8 and the light emitting element 10 is disposed inside the arm portion 3. For example, the arm portion 3 is configured only by the flexible pipe 8 formed in a coil shape, and a plurality of light emitting elements 10 are provided on the outer peripheral surface of the flexible pipe 8 along the axial direction.
