Hereinafter, the operation and effect of the lighting device 1 having the above-described configuration will be described.

Since the lighting device 1, the hole 42, the light supporting member 44, the coupling portion 46 and the elastic portion 48 of the present embodiment is provided with an illumination connection portion 40, 30) there is an advantage that the vertical movement and the axial rotation movement can be made smooth and stable.

In FIG. 7, a diagram in which vertical movement of the illumination unit 30 is continuously expressed is illustrated. The upper and

lower protrusions

323 and 327 protruding to one side of each of the upper and lower cases 342 and 346 constituting the light source case 32 have a coupling part 46 therebetween, and the coupling part 46 It is fixed, and the coupling portion 46 composed of the upper member 462 and the lower member 464 again supports the head 446 of the lighting support member while being wrapped, and the head 446 is an elastic portion ( Since it is strongly elastically supported inside the coupling portion 46 by the elastic recovery force of 48, it is possible to make the movement of the lighting portion 30 in the vertical direction smooth and reliable.

That is, by the restoring force of the spring 482 forming the elastic portion, the pressing member 484 directly presses the inner surface of the coupling portion 46, and at the same time the one side surface 449 of the head 446 is the coupling portion 46 Since the light source case 32 fixed to the engaging portion 46 is in any position, it is possible to stably maintain its position without sagging of the lighting portion 30 because the light source case 32 fixed to the engaging surface 46 is pressed by the same force.

As shown in FIG. 7, the position of the lighting unit 30 is at the position (a), or the position of the lighting unit is moved to the position (b) by the user holding the lighting unit 30 and pushing downward. Even if it is moved to the position, it is provided with a light connecting portion 40 for connecting the lighting unit 30 and the rod member 20 of the above-described configuration, such that the lighting unit 30 sag due to the weight of the lighting unit 30 Not only does not occur, there is an advantage that the user can have a feeling that the movement of the lighting unit 30 is smooth.

In addition, in the present embodiment, since the coupling portion 46 further includes a lower plate spring 49 for elastically supporting the coupling portion 46 from the bottom, the coupling portion 46 has the head 446 of the elastic portion 48. In addition, it is possible to pressurize additionally in the vertical direction different from the pressing direction. As a result, the lighting unit 30 is more stable, and the vertical and horizontal rotational movement about the head 446 is made stable and maintained at a specific position. It has the advantage of being.

In addition, in the present embodiment, as illustrated in FIG. 8, the lighting support member 44 is rotatably fitted to the hole 42 in the rod member, and has an O-ring on the outer surface of the lighting support member 44. Since the lighting unit 30 of the lighting connector 40 has the advantage that the rotation of the clock member and the counterclockwise rotation about the axis of the rod member 20 is possible.

That is, referring to FIG. 8, if the user grasps the lighting unit 30 at the position indicated by (a) and rotates it clockwise around the longitudinal axis of the lighting support member 44, the operation is indicated by (b). To the correct position. When the user rotates the lighting unit 30 counterclockwise, it is possible to rotate through the position (a) to the position (c). The user may change the lighting unit 30 to any desired position by rotating the lighting unit 30.

At this time, the axially rotatable angle of the lighting unit 30 is limited to the range in which the groove 447 is formed due to the action of the groove 447 and the protrusion 422. In addition, since the O-ring 443 is provided, the rotation can be made more smoothly.

As a result, the user can change the posture of the lighting unit 30 in the up and down direction as shown in FIG. 7 and rotate it clockwise and counterclockwise in the axial direction as shown in FIG. There is an advantage that it is possible to position 30.

In addition, in the present embodiment, since the light source case is a ring shape as a whole, there is an advantage that the user is easy to hold by hand when changing the position of the lighting unit. In addition, since a plurality of light sources are arranged along the ring-shaped circumference, there is an advantage that the illuminance of the portion irradiated by the illumination unit is uniform.

On the other hand, Figures 9 to 11 show an embodiment in which a part of the configuration of the previous embodiment is modified. 9 is a view showing a state in which the pressure spring is coupled to the coupling portion, Figure 10 is a view for explaining a state in which the pressure spring is coupled to the coupling portion, Figure 11 is a view of the pressure spring viewed from the side.

In the above embodiment, a plate-shaped lower plate spring 49 is elastically deformed to press the lower member 464 between the lower member 464 and the lower case 327 of the coupling portion 46. Correspondingly, in the present embodiment, the coupling portion 46 is elastically deformed, and is provided with a “c” shaped pressing spring 49a for pressing the coupling portion 46. 9 to 11, the pressure spring 49a is shown in the direction of rotation 180 degrees clockwise so that the open portion of the "c" shape toward the left side.

In addition, the pressure spring 49a of this embodiment is integrally formed by bending one member of the iron material having strong elasticity. The press spring 49a is comprised from the upper part 492a, the lower part 494a, and the side part 496a.

As shown in FIG. 11, the upper portion 492a is acute with the side portion 496a, and the lower portion 494a is configured with the acute angle with the side portion 496a. The acute angle means an angle of 90 degrees, and the smaller the angle, the greater the amount of elastic deformation, so that the pressing force due to the restoring force is increased. Due to this configuration, as illustrated in FIG. 10, the pressure spring 49a is elastically deformed in a direction in which the upper portion 492a and the lower portion 494a are spaced apart from each other, and is fitted to the coupling portion 46. As a result, the upper portion 492a and the lower portion 494a strongly press the coupling portion 46.

In the case of the previous embodiment, the lower plate spring 49, the upper case 323 and the lower case 327 was able to press the lower member 464 of the coupling portion 46 only when the mutual coupling, but the letter "c" In the present embodiment having a pressure spring 49a having a shape, the upper and

lower cases

323 and 327 are mutually coupled so that the pressure springs 49a are not joined to each other. Even if the elastic part is fitted to the portion 46, there is an advantage that the coupling portion 46 can be pressed in the vertical direction. As a result, the movement of the lighting unit 30 may be more firmly and stably controlled.

Configurations that are not described among the configurations illustrated in the drawings are the same as the configurations of the foregoing embodiment, and thus description thereof will be omitted.
