The pivot shaft 22c of the light emitter 2 is inserted into the bearing 33, and the bearing 33 supports the pivot shaft 22c so as to be rotatable and slidable in the axial direction of the bearing 33. In this manner, the pivot 22c and the bearing 33 make the light emitter 2 rotatable with respect to the arm 3, make the angle formed by the light emitting surface 2a of the light emitter 2 and the mounting surface 4a of the main body 4 variable, and the first The shaft 31 is configured. The pivot 22c and the bearing 33 constitute a double-shaft structure that enables movement of the pivot 22c along the bearing 33 in the above-described deployed state, that is, movement of the light emitter 2. The angle range in which the light emitter 2 can be rotated is, for example, approximately 360 degrees. The movement of the bearing 33 in the axial direction is preferably limited by a stopper or the like provided at the distal end portion 3 a of the arm 3.

  When the light emitter 2 is rotated, the hole 3b and the bearing 33 act as a frictional force between them, so that the rotation of the bearing 33 is braked and the rotation due to the weight of the light emitter 2 is suppressed. Each diameter is adjusted. Thereby, the light emitter 2 can be held at an arbitrary inclination.

  A slit 3c is provided on the upper surface of the tip 3a of the arm 3 so as to be connected to the hole 3b in parallel with the axial direction of the hole 3b. The slit 3c is for passing the protrusion 22b of the light emitter 2 when the light emitter 2 is moved along the bearing 33, and the width of the slit 3c is slightly smaller than the width of the protrusion 22b of the light emitter 2. A wide range is desirable. The length of the arm 3 is substantially equal to the dimension of the light emitter 2 in the short direction. The arm 3 is formed in a hollow shape, and an electric wire led out from the planar light source 21 and connected to a circuit in the main body 4 is accommodated therein.

  4A and 4B show an organic EL panel 21a constituting the planar light source 21. FIG. At the end of the organic EL panel 21a, for example, two electrical contacts 21b for electrical connection with an external power source are disposed on the light emitting surface 2a side. The electrical contact 21b may be provided on the non-light emitting surface side. The electrical contact 21b is formed, for example, by plating or vapor-depositing a metal, attaching a metal plate, or mixing and molding a plastic with a conductive material.

  The organic EL panel 21a includes an organic light emitting layer 21e between a transparent electrode 21c made of a transparent conductive thin film made of ITO (indium tin oxide) or the like and a plate-like metal electrode 21d made of aluminum or the like.

The organic light emitting layer 21e is composed of EL elements of each color, and it is desirable to irradiate white light under dimming control for each color, but the irradiation light color is not limited to this. Each color EL element may be laminated or juxtaposed.

  Next, various usage methods of the lighting fixture 1 comprised as mentioned above are demonstrated with reference to FIGS. FIGS. 5A and 5B and FIGS. 6A and 6B show a state when the lighting apparatus 1 is used on a desk or the like as an example of use. In FIG. 5 and FIG. 6, the inclinations of the light emitter and the arm are different. The user places the main body 4 on a desk or the like, raises the arm 3, moves the light emitter 2 away from the mounting surface 4 a of the main body 4, and sets the above-described unfolded state. Then, as shown in the figure, a magazine or book (hereinafter referred to as a magazine) is opened and placed on the mounting surface 4a of the main body 4 or in front of the main body 4, and the light emitting surface 2a of the light emitter 2 is directed to the paper surface. The light emitting surface 2a of the light emitter 2 is turned on to illuminate the paper surface when the power is turned on in the above state. The user adjusts the distance between the light emitter 2 and the paper surface by adjusting the inclination of the arm 3 according to the size of the paper surface. As shown in FIG. 5, when the paper surface is small, the inclination of the arm 3 is increased to bring the light emitter 2 closer to the paper surface, and as shown in FIG. 6, the arm 3 is inclined when the paper surface is large. To reduce the distance between the light emitter 2 and the paper surface. In addition to the tilt of the arm 3, the tilt of the light emitter 2 is also adjusted to control the light distribution so that the entire paper surface is illuminated.

  FIG. 7 shows a state in which the light emitter 2 is moved along the first axis 31 in the above use example. When the light emitter 2 and the arm 3 are arranged in a substantially straight line in a side view, when the light emitter 2 is pushed in the axial direction of the first shaft 31, it moves in that direction. In order to move the light emitter 2 in this way, as shown in FIG. 3B, the position of the protrusion 22b of the light emitter 2 is aligned with the slit 3c of the arm 3, and then the light emitter 2 is moved to the first position. It is necessary to push in the axial direction of the first shaft 31. When the light emitter 2 is pushed, the protruding portion 22b passes through the slit 3c, the pivot 22c of the light emitter 2 slides within the bearing 33, and the entire light emitter 2 moves in the axial direction of the first shaft 31. The light emitter 2 is lit in the moved state. When the user moves the light emitter 2 and rotates the light emitter 2 around the first shaft 31 with the slit 2b corresponding to the position of the tip 3a of the arm 3, the tip of the arm 3 is moved. The part 3a passes through the slit 2b. The light emitter 2 is further rotated without being restricted by the arm 3, and the light irradiation direction is changed around the first axis 31.

  FIG. 8 shows a usage example in which the lighting apparatus 1 is attached to the chest pocket P1 of the clothes by the clip portion 42 as another usage example. The user U1 inserts the main body 4 into the breast pocket P1 of the clothes, sandwiches the breast pocket P1 with the clip portion 42, and takes out the light emitter 2 from the breast pocket P1. The light emitter 2 is turned on when the power is turned on, irradiates light in front of the user U1 (an example of a light irradiation range is indicated by a broken line), and illuminates a personal computer or the like placed there.

  FIG. 9 shows a usage example in which the lighting fixture 1 is attached to a magazine or the like by the clip portion 42 as another usage example different from the above. The user U1 uses the clip portion 42 to pinch the upper part of the magazine B1 and raises the arm 3, and then raises the light emitter 2 so that the light emitting surface faces the paper surface. The illuminator 2 is turned on when the power is turned on, and irradiates the paper with light.

  In the present embodiment, the light emitter 2 can be rotated around the first axis 31, and the light irradiation direction can be changed around the rotation axis. Furthermore, the light emitting body 2 is moved along the first shaft 31 by the double shaft structure of the first shaft 31, or the light emitting body 2 is further rotated in this state to change the light irradiation direction. Can do. In addition, interference with the light emitter 2 by the arm 3 can be prevented by the slit 2b, and the rotation restriction of the light emitter 2 by the arm 3 can be prevented. For this reason, the light irradiation possible range can be widened.

  Further, since the clip portion 42 can be fixed to the breast pocket P1 of clothes or a magazine or the like, the clip portion 42 can be used without being held in a hand or when there is no place for placement.

  In addition, as shown in FIG. 10, when the upper part of one page of the facing paper in the magazine B1 or the like is sandwiched between the clip portions 42, the light emitter 2 is moved along the first axis 31 to open the facing paper. The light emitter can be moved to approximately the center in the horizontal direction. For this reason, the facing paper surface can irradiate light on the entire facing paper surface.

  The light emitter 2 is not limited to a horizontally long substantially rectangular shape, and may be a vertically long substantially rectangular shape as shown in FIG. 11, for example. In this case, the length of the arm 3 is substantially equal to the longitudinal dimension of the light emitter 2, and the shape of the housing 41 of the main body 4 in plan view is a substantially vertically long and substantially rectangular shape.

  Moreover, as a method of attaching the planar light source 21 to the cover 22, there are, for example, a method of mechanically fitting or a method of bonding with an adhesive. When a method capable of separating the planar light source 21 from the cover 22 after the attachment is selected, for example, only the planar light source 21 can be replaced and the cover 22 can be reused, and the replacement cost can be reduced. Further, the planar light source 21 and the cover 22 made of different materials can be disposed of separately, so that they can be recycled and contribute to the protection of the global environment.

  Further, a cushioning member such as rubber may be provided between the planar light source 21 and the cover 22 along the periphery of the planar light source 21 or at a part of the edge. In this case, the strength and impact resistance of the light emitter 2 can be improved. Alternatively, the buffer member may be formed of a conductive material, and the buffer member other than the contact portion with the electrical contact 21b may be covered with insulation.

  Moreover, the planar light source 21 may be comprised with the LED panel by which several LED21g is arrange | positioned, as FIG. 12 shows. The LED 21g is configured by, for example, a red LED, a green LED, or a blue LED. When the LED 21g is composed of LEDs of a plurality of colors, the color component of the illumination light can be changed by controlling the current supplied to each color LED.

  Moreover, when the planar light source 21 includes the above-described LED panel, each LED 21g may be controlled to be lit by a control circuit independently. In this case, the control circuit is composed of a one-chip microcomputer incorporating a ROM or RAM in which a plurality of light emission patterns having different light emission intensities are stored in advance. This one-chip microcomputer selects a light emission pattern according to the operation of the operation switch, and increases or decreases the supply current value to each LED 21g or the duty ratio of the PWM control signal to each LED 21g according to the selected light emission pattern. Control.

  Each arm 3 is composed of an upper arm 34 and a lower arm 35 as shown in FIGS. 13A to 13C. One end of each of the upper arm 34 and the lower arm 35 is rotated. You may connect freely. In this case, as shown in FIG. 13 (a), in the folded state, the upper arm 34 and the lower arm 35 are folded at the connecting portion and placed on the mounting surface 4a of the main body 4. As shown in FIGS. 13B and 13C, in the developed state, the upper arm 34 and the lower arm 35 are extended, and the light emitter 2 is separated from the main body 4.

(Second Embodiment)
14 (a) and 14 (b) show a lighting fixture 1 according to a second embodiment of the present invention. The lighting fixture 1 of this embodiment is further provided with the substantially plate-shaped translucent member 5 for carrying out light distribution control of the light emitted from the light-emitting body 2, compared with 1st Embodiment. The translucent member 5 is held by the arm 3 in the folded state and is sandwiched between the light emitter 2 and the main body 4, and along the arm 3 and the side edge 22 d of the cover 22 of the light emitter 2 in the unfolded state. It is possible to slide to the front surface of the light emitter 2.

  A groove 3 d is provided along the extending direction of the arm 3 on the inner side surface of the arm 3, that is, on the opposite side surface of the pair of arms 3. A groove 22e is also provided on the side edge 22d of the cover 22 of the light emitter 2, that is, the side surface along the side edge 22d. The grooves 3d and 22e are provided so as to be a continuous groove in a state where the arm 3 and the side edge 22d of the light emitter 2 are substantially straight in a side view.

  The translucent member 5 includes a sheet-shaped or film-shaped light distribution member 51 and a holding member 52 that holds the light distribution member 51 from both ends. The light distribution member 51 has an area substantially equal to the light emitting surface 2 a of the light emitter 2. The light distribution member 51 directs the emitted light from the light emitter 2 in a desired direction to give it directivity, or makes the illuminance by the emitted light uniform. The light distribution characteristics by the light distribution member 51 are not limited to the above. The material of the light distribution member 51 can be a resin composition such as plastic, or glass, but is preferably a material that is difficult to break such as plastic.

  The holding member 52 engages with the protrusion 52a that engages with the groove 3d of the arm 3 in the folded state, and with the groove 22e of the light emitter 2 when the light distribution member 51 is moved to the front surface of the light emitter 2 in the unfolded state. And a protrusion 52b. The protrusions 52 a and 52 b slide in the groove 3 d of the arm 3 and the groove 22 e of the light emitter 2 to guide the movement of the light emitter 2. The protruding portion 52b of the holding member 52 and the groove 22e of the light emitter 2 are engaged with each other so that a frictional force acts between the protrusion 52b and the groove 22e so that the holding member 52 is braked and the sliding movement due to the weight of the translucent member 5 is suppressed. The size and shape are adjusted. Thereby, the translucent member 5 can be fixed on the front surface of the light emitter 2. The holding member 52 is provided along both side edges of the light distribution member 51, and the length thereof is slightly shorter than the length of the arm 3 or the dimension of the light emitter 2 in the short direction.

  Next, the usage method of the lighting fixture 1 comprised as mentioned above is demonstrated with reference to FIG. 15 (a)-(d) in addition to said FIG.14 (b). First, it is assumed here that the lighting fixture 1 is in a folded state as shown in FIG. In this state, the translucent member 5 is sandwiched between the light emitter 2 and the main body 4. The user raises the arm 3 as shown in FIG. 15B and further rotates the light emitter 2. Then, as shown in FIG. 15C, the arm 3 and the side edge of the light emitter 2 are in a substantially straight line when viewed from the side. In this state, when the translucent member 5 is pushed up, the protruding portion 52a of the holding member 5 slides in the groove 3d of the arm 3, and the protruding portion 52b slides in the groove 22e of the light emitter 2. FIG. ), The light distribution member 51 is guided and disposed on the front surface of the light emitting surface 2a of the light emitter 2, and is fixed in that state by the frictional force between the protruding portion 52b and the groove 22e. The light emitter 2 is turned on when the power is turned on, and the light distribution member 51 distributes the light emitted from the light emitter 2.

  In the present embodiment, the light distribution control by the light transmissive member 5 can be performed by sliding the light transmissive member 5 from the position held by the arm 3 to the front surface of the light emitter 2. Moreover, since the light distribution control can be performed simply by sliding the translucent member 5, the operation required for the control is easy.

  Further, when light distribution control is not required, the translucent member 5 is returned to the position held by the arm 3 to irradiate diffused light, which is direct light from the light emitter 2, or transmit light. Whether to irradiate light whose light distribution is controlled by the optical member 5 can be switched.

  Moreover, since the translucent member 5 is sandwiched between the light emitter 2 and the main body 4 in the folded state, the light distribution member 51 can be protected so as not to be damaged, and compared with the first embodiment, Even if the translucent member 5 is further provided, the compactness can be maintained. Further, since the translucent member 5 is held by the arm 3 or is slid and fixed to the side edge of the light emitter 2, it is not necessary to attach or detach the translucent member 5, and therefore it is not necessary to carry it separately.

(Third embodiment)
FIGS. 16A and 16B show the lighting fixture 1 according to the third embodiment of the present invention and various states thereof. The lighting fixture 1 of this embodiment is different from the first embodiment in that the light emitter 2 has flexibility and the dimension in the direction of the first axis 31 is variable. FIG. 16A shows a state in which the light emitter 2 is extended in the direction of the first axis 31, and FIG. 16B shows a state in which the light emitter 2 is bent. When the light emitting body 2 is bent with the above-described dimensions being reduced, the back surface of the light emitting body 2 bulges as shown, or the front surface of the light emitting body 2, that is, the light emitting surface 2a bulges.

The pivot 22c is provided only at the lower portion of the cover body 22a that covers the side edge of the planar light source 21.

  The pivot 22 c is inserted into the bearing 33 and is slidable in the extending direction of the bearing 33. The pivot 22c and the bearing 33 are adjusted in size and shape so that frictional force acts between the pivot 22c and the pivot 22c is braked to suppress sliding movement due to the repulsive force of the light-emitting body 2 that has been bent. Thereby, the pivot 22c can be fixed at a desired position.

  In the present embodiment, the light distribution can be adjusted by simply bending the light emitter 2, and the adjustment becomes easy. In addition, when the light emitter 2 is bent and the light emitting surface 2a bulges forward, the light distribution spreads. When the light emitter 2 bulges in the back direction, the light distribution becomes narrow. The adjustment range can be widened.

  In addition, this invention is not limited to the structure of the said 1st-3rd embodiment, A various deformation | transformation is possible according to a use purpose. For example, the shapes of the light emitter 2 and the main body 4 are not limited to the above as long as the entire lighting fixture 1 can be thinned.
