Description

  The present invention relates to a lighting device.

Conventionally (for example, refer to Patent Document 1), there has been a lighting device including a plurality of lamps connected between two electric wires stretched in parallel.
Japanese Utility Model Publication No. 4-46329

  However, since the lamp is a spotlight, it is difficult to distribute light uniformly and widely, and it is necessary to connect the parallel wire and the lamp with a conductor arm. In addition, since the longitudinal direction of the spotlight is the light irradiation direction, a balance weight is required to balance the weight of the lamp when the light irradiation direction is changed, which increases the size of the lamp and complicates the structure.

  Accordingly, an object of the present invention is to provide an illumination device that enables wide and uniform light distribution, has a simple instrument configuration, and is easy to install.

The lighting device according to the present invention includes a U-shaped support body having one opening, a conductor having a strip shape provided on an inner surface of the support body, and the strip plate inserted into the support body. A lamp having a protrusion sandwiched between the conductors and having electrodes that are provided on both sides of the protrusion and are in contact with the conductor . The lamp body has a substantially flat plate shape. The ridge protrudes outward from one side of the lamp body on the mounting side of the lamp body and extends along the one side. The electrodes are provided on both sides of the ridge and extend along the longitudinal direction of the ridge.

According to the illuminating device of the present invention, compared to the conventional example that requires a balance weight and a conductor arm, the fixture structure is simplified, and the lamp body can be easily attached to the support body.

  A first embodiment of the present invention will be described with reference to FIGS. In other words, the lighting device includes the support bodies 1 a and 1 b and the lamp body 2.

  The supports 1 a and 1 b are linear rigid bodies having a conductor 7, for example, wires, and the surfaces are covered with an insulator 8. The supports 1a and 1b are wired in parallel and are tensioned. The conductor 7 serves as a power supply line, and one end of the conductor 7 is connected to a power supply device (not shown). One support 1a is on the high voltage side, and the other support 1b is on the low voltage (common) side.

  The lamp body 2 has a substantially rectangular plate shape, has a light source 3 such as an organic EL lamp unit that emits light when supplied with electric power, and forms a light emitting surface on the entire surface excluding the peripheral edge of the lamp body 2. The holding body 5 is provided at the peripheral edge portions on both sides of the lamp body 2, and the connecting portion 5 b of the holding body 5 and the light source 3 are electrically connected to each other, and are attached to the connecting portions 5 b of the holding body 5 on the supports 1 a and 1 b The support portions 4 to be rotated are connected by ordinary connecting means so as to be rotatable. In this case, the support portion 4 is configured to be frictionally locked to the connecting portion 5b of the holding body 5 at the rotation position, and the support portion 4 and the connecting portion 5b are electrically connected. In order to balance the weight, the line connecting the pair of support portions 4 passes through the center of the lamp body 2.

  The support portion 4 has a support body insertion groove 6 formed by a substantially L-shaped notch, and the support bodies 1a and 1b are inserted and locked in the support body insertion groove 6 so as to be detachable. Further, contact means (not shown) that cuts into the insulator 8 and comes into contact with the conductor 7 is provided in the support portion 4.

  According to this embodiment, the two support bodies 1a and 1b are stretched in parallel, and can be easily attached by inserting the support body insertion grooves 6 of the support section 4 into the respective support bodies 1a and 1b. Since the lamp body 2 has a flat plate shape and can emit a surface, a wide and uniform light distribution is possible. Moreover, since the two support parts 4 can each turn, it can rotate around the axis line which connects the support parts 4, and, thereby, the lamp body 2 can be rotated with respect to the support bodies 1a and 1b. The direction of the lamp body 2 can be easily changed, and the irradiation direction can be easily changed to an arbitrary angle.

  The support bodies 1a and 1b can be freely arranged according to the size of the lamp body 2, and the lamp body 2 can be made thinner because the support section 4 is disposed at the peripheral edge of the lamp body 2. When a rigid body is used for the supports 1a and 1b, the lamp body 2 can be held by elasticity, and attachment and removal are easy.

  In the case of a low-voltage circuit, the support insulator 8 may be omitted.

  Each of the plurality of lamps 2a to 2d is attached between two supports 1a to 1d which are selected from the supports 1a to 1d and which are separated from each other and have different polarities.

  Arbitrary numbers of lamps can be arranged by installing a plurality of supports 1a to 1d, and the brightness can be freely changed.
