  However, when these V-shaped springs are used as in these prior arts, a large amount of force is required to narrow the interval between the springs against the urging force of the springs with fingers, and the fingers are properly applied with force. Since the tip of the V-shaped spring has to be inserted into the spring receiver provided in the main body while maintaining the narrowed interval, it is difficult to easily and quickly position the LED module. There was a problem that the work required time and effort.

  Further, in general lighting devices such as these conventional techniques, most of them are provided with a spring on the LED module side, and this spring is engaged with a spring receiver provided on the main body. In addition, if a spring is provided on the side of the LED module that is suspended from the main body, the operator applies a force to the finger to reduce the distance between the springs against the biasing force of the spring, and at the same time holds the spring and suspends it from this spring. The LED module that has been lowered must be lifted upward, and there is a problem that the mounting operation is not easy.

  Furthermore, in particular, when a plurality of such V-shaped springs are provided opposite to both side surfaces in the longitudinal direction of the straight tube type LED module, the number of work points, and thus the number of work steps increases. There was also a problem of decreasing the sex.

Accordingly, the positioning of the LED module 14 is easy, and the spring 22 is provided at both ends in the longitudinal direction of the lighting device 10 (when the springs 22 are provided at two ends and provided at a total of four locations). The mounting location on the spring receiver 20 and thus the number of work steps can be reduced, and the mounting work can be further simplified. As described above, the spring 22 and the spring receiver 20 can be installed at the central portion in the width direction of the lighting device 10. In the present invention, the following characteristic spring 22 and spring receiver 20 are used. Can be realized.

(3-1 Spring)
That is, the spring 22 according to the present invention extends from the coil spring portion 22 and a plurality of coil spring portions 22A arranged opposite to the top surface of the groove portion 12A of the main body 12, as shown in FIGS. The frame portion 22B is formed in a frame shape. Therefore, unlike the V-shaped spring that has been conventionally used, it can be attached to the spring receiver 20 without performing work such as narrowing the distance between the springs at both ends with two fingers.

  More specifically, as shown in FIGS. 3 and 4, the frame portion 22B of the spring 22 is formed so as to extend from one coil spring portion 22A, bend twice, and be taken up by the other coil spring portion 22A. It can be formed in a substantially U-shaped shape. Thereby, it can be easily elastically deformed by hooking one finger across the left and right of the frame portion 22B. For this reason, the operator can easily engage the spring receiver 20 simply by lifting the frame portion 22B with one finger or the like, and the LED module 14 can be easily attached. .

  In this case, in particular, as shown in FIGS. 4 and 6 to 9, it is desirable to provide a bent portion 24 in a part of the frame portion 22B. Thereby, as shown in FIGS. 4, 6 and 8, the frame portion 22B is arranged so that a part of the frame portion 22B rises from the installation surface in a free state. The frame 22B can be easily lifted by being inserted into the space, and the mounting work is further simplified. In the illustrated embodiment, the frame portion 22B is a bent portion 24 bent toward the coil spring portion 22A, and the bent portion 24 itself is raised, but is suitable for inserting a finger for work. On the contrary, the coil spring portion 22A may be bent toward the opposite side so that the tip of the U-shaped frame portion 22B is lifted from the main body 12. it can.

  Further, as shown in FIGS. 3 and 4, the spring 22 has a frame portion 22B on the surface on which the coil spring portion 22A is installed (in the illustrated embodiment, the top surface of the groove portion 12A of the main body 12). It is energized towards. Accordingly, as shown in FIGS. 6 and 7, the frame portion 22B is lifted against the biasing force and inserted into the spring receiver 20 provided in the LED module 14, and then the elastic deformation is released. As shown in FIGS. 8 to 10, the spring 22 can attract the spring receiver 20, whereby the LED module 14 having the spring receiver 20 can be attached to the main body 12.

  In this case, as shown in FIGS. 3, 4, and 6 to 9, the spring 22 is arranged such that the frame portion 22 </ b> B extends from the coil spring portion 22 </ b> A in the longitudinal direction of the lighting device 10. For this reason, when the LED module 14 is mounted in the long straight tube type lighting device 10, the displacement in the longitudinal direction is larger than the case where the LED module 14 is mounted by being displaced in the width direction of the lighting device 10. A sufficient amount can be secured, and the mounting operation can be facilitated.

  Furthermore, it is desirable for the spring 22 to set the installation interval between the two coil spring portions 22A to be larger than the width of the frame portion 22B. As a result, the strength of the base portion of the frame portion 22B that is greatly elastically deformed is improved, and the LED module 14 can be stably held after being mounted on the spring receiver 20, as shown in FIGS.

In the illustrated embodiment, the frame portion 22B of the spring 22 is linearly formed from a single spring material. However, the shape is not particularly limited as long as it is a frame shape. Or an arcuate frame portion 22B. Similarly, it is not limited to the case of forming from a single spring material, and a plurality of spring materials can be combined to form the spring 22.

On the other hand, the spring receiver 20 has a concave spring receiver main body 20A and a flange portion 20B formed so as to extend from the spring receiver main body 20A to the left and right as shown in FIGS. Then, the flange portion 20B is fixed to the LED module 14 by an appropriate means such as a bolt, so that the LED module 14 is attached to a position corresponding to the spring 22 installed on the main body 12.

  As shown in FIGS. 8 to 10, the spring 22 is in a free state after the frame portion 22B is inserted into the space formed between the concave spring receiving body 20A and the top surface of the LED module 14. As a result, the spring receiving body 20A, and consequently the LED module 14, can be pulled toward the body 12 side.

  In this case, as shown in FIGS. 5 to 10, the spring receiver 20 can be locked to the frame portion 22 of the spring 22 when the frame portion 22B of the spring 22 is inserted into the spring receiver 20 or the like. A locking piece 26 is provided. Therefore, in particular, as shown in FIG. 7, after the frame portion 22B of the spring 22 is raised to the LED module 14 side against the biasing force, the locking piece 26 is laid across the frame portion 22B. By simply hooking, the LED module 14 can be easily positioned at an appropriate position, and at the same time, the LED module 14 can be temporarily suspended and temporarily fixed, so that the mounting operation can be easily performed. Accordingly, the width of the locking piece 26 is set smaller than the width (interval) of the frame portion 22B of the spring 22, as shown in FIGS.

  Further, as shown in FIGS. 5 to 9, the spring receiver 20 is formed with an insertion assisting portion 28 cut out along a part of the frame shape of the frame portion 22 </ b> B of the spring 22. As shown in FIGS. 8 and 9 in particular, the insertion assisting portion 28 is relatively long in the longitudinal direction with respect to the frame portion 22B arranged so that the spring receiver 20 extends in the longitudinal direction of the lighting device 10. While permitting the displacement, it has a role of guiding the displacement by displacing along the insertion assisting portion 28, and the spring 22 enables the spring receiver 20 to be drawn smoothly. For this reason, positioning at the time of inserting the spring 22 into the spring receiver 20 can be performed appropriately, and the mounting operation can be performed more smoothly and accurately.

(4. How to use)
Next, in the lighting device 10 of the present invention, the procedure for mounting the LED module 14 on the main body 12 will be described. As shown in FIG. The spring receiver 20 is disposed at a position corresponding to the spring 22 provided at the actual value 12.

  Next, a finger or the like is hooked on the frame portion 22B of the spring 22 provided in the main body 12 to pull it out toward the LED module 14 against the urging force of the spring, and as shown in FIG. The frame portion 22 of the spring 22 is hooked on the stop piece 26. This operation is performed on the two springs 22 shown on the left and right sides in FIG. 3, and then the LED module 14 is pushed up toward the main body. And the LED module 14 is attracted to the main body 12, and the LED module 14 is mounted at a predetermined position with respect to the main body 12 as shown in FIGS. 8 to 10.

  On the other hand, when the LED module 14 is removed from the main body 12 for maintenance or replacement, the LED module is pulled down against the urging force of the spring 22, and as shown in FIG. The frame 22B of the spring 22 is hooked on the locking piece 26 of the spring receiver 20 provided on the spring receiver 20 and can be removed. In this case, in order to prevent the LED module 14 from being unexpectedly dropped, if the main body 12 and the LED module 14 are connected by a string (not shown), damage or the like due to the drop of the LED module 14 can be prevented. .
