DETAILED DESCRIPTION OF THE INVENTION
(Embodiment 1)
Embodiment 1 of the present invention will be described with reference to FIGS. As shown in FIGS. 1 and 2, the LED lighting fixture wall according to the present embodiment has a long mounting base 1 having a U-shaped cross section and a large number of LEDs 2 that are fitted into the upper portion and disposed therein. The lid part 3 is provided. The mounting base 1 is formed of a metal or a resin, and has a specific shape of about 20 mm in width, about 15 mm in height, and about 1 m in length. The side surface of this material has elasticity so that the lid 3 described later can be fitted. The inside of the mounting base 1 is hollow so that various electric devices can be arranged. A terminal plate 5 is attached to the terminal portion of the mounting base 1. The lid 3 is fitted so as to cover the opening at the top of the mounting base 1 and is made of a transparent insulating material such as acrylic resin or glass. The length of the lid 3 is about half that of the mounting base 1. Therefore, as shown in FIG. 1, the two lid portions 3 can be fitted to one mounting base 1. In the upper part of the inside of the lid part 3, the LEDs 2 attached to the substrate 10 are arranged at intervals of 5 to 10 cm. An electrical component 11 for lighting the LED 2 is disposed at the lower portion of the substrate 10, and a heat transfer sheet 12 is disposed at the lower portion. The LED 2, the substrate 10, the electrical component 11, and the heat transfer sheet 12 are disposed on an insulating plate 13 that is held by being fitted to the lid 3. Further, the lower portion of the insulating plate 13 in the mounting base 1 is a space for arranging the power wiring 14.
[0012]
The attachment procedure of the LED lighting apparatus of this embodiment is demonstrated. First, the attachment base 1 is attached to a floor surface or a wall surface. Here, as a configuration of attachment, when it is attached for a long period of time, it is securely fixed with screws or nails, and when it is attached only for a short period of time, a double-sided adhesive tape is used. Next, when the power wiring 14 for supplying electricity to other electrical devices is required, the power wiring 14 is disposed on the bottom surface of the mounting base 1. On the other hand, the heat transfer sheet 12 and the insulating plate 13 provided with the substrate 10 provided with the LED 2 on the upper side and the electrical component 11 on the lower side are fitted inside the lid 3. The lid 3 is fitted so as to cover the opening of the mounting base 1. In the present embodiment, the lid 3 is fitted inside the side plate of the mounting base 1. On the other hand, the power wiring 14 is pulled out from the terminal end of the mounting base 1 and connected to necessary electrical equipment.
[0013]
Further, when the mounting base 1 is disposed in a place where the LED illumination is not required, the LED non-storage lid portion 4 is fitted into the opening of the mounting base 1 as shown in FIG. This non-LED storage lid 4 uses an opaque resin so that the inside cannot be seen. In this portion, only the power wiring 14 is accommodated. In this state, the LED can be blinked by turning on or off the LED switch (not shown). Here, if the LED lighting fixture of this embodiment is arrange | positioned on a floor surface, it can be used as a guide light. Moreover, if it arrange | positions on the wall and ceiling of a store lamp, it can be used as local illumination of a display product.
[0014]
Since the LED lighting apparatus of this embodiment has a structure in which the power wiring 14 can be disposed inside, the electric wires to various electric devices can be disposed inside to improve the appearance. Moreover, as the mounting base 1 and the cover parts 3 and 4, the components of a commercially available wiring rail can be diverted. Therefore, cost can be reduced by diverting commercially available parts. Moreover, the attachment base 1 of the LED lighting fixture of this embodiment and the LED non-storage lid | cover part 4 can also be used conversely as a wiring rail. On the other hand, since the LED is used as the lighting device, power consumption is small, and heat generation inside the LED lighting fixture can be suppressed. Furthermore, since the heat transfer sheet is provided inside the LED lighting apparatus, temperature rise can be suppressed.
[0015]
(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIGS. The present embodiment is similar to the first embodiment, but there is a difference in the structure of the mounting base 1 ′ and the lid portions 3 ′ and 4 ′. This point will be described. The mounting base 1 ′ and the LED non-storage lid 4 ′ use a commercially available wiring molding. For this purpose, the lid portions 3 ′ and 4 ′ are fitted to the outside of the side plate of the mounting base 1 ′. In addition, since the lid 3 'houses the LEDs therein, the height of the lid 3' is higher than that of the lid 4 'as shown in FIG. Here, the lid 3 ′ has an internal structure substantially similar to that of the lid 3 described in the first embodiment.
[0016]
Since the LED lighting apparatus of the present embodiment uses a commercially available wiring molding as the mounting base 1 ′ and the LED non-storage lid 4 ′, it is possible to use a commercially available commercial product as it is. Therefore, the number of parts in stock can be reduced, and the cost can be reduced.
[0017]
As shown in FIG. 4, when a commercially available LED non-housing cover 4 ′ is used, the height of the cover is different and the appearance is impaired. In this case, the height of the lid can be made uniform by manufacturing a non-LED storage lid having the same height as the LED built-in lid 3 ′ and fitting it to the mounting base 1 ′. However, in this case, since the LED non-storage lid is a custom-made product, the cost may increase.
[0018]
(Embodiment 3)
A third embodiment of the present invention will be described with reference to FIGS. The present embodiment is similar to the first embodiment, but differs in that electrode terminals 6 for LED power supply wiring are arranged on the end plate 5 of the mounting base 1. By connecting the electrode terminals 6 to each other, the LED lighting apparatus can be easily connected without connecting the LED power supply wiring.
[0019]
In the LED lighting apparatus of this embodiment, since the electrode terminal 6 is disposed on the terminal plate 5 at the end of the mounting base 1, the LED lighting apparatus can be easily electrically connected. Therefore, it becomes possible to easily connect and arrange a large number of LED lighting fixtures.
[0020]
Here, in order to dispose the power wiring 14 inside the mounting base 1 and connect the power wiring 14 via the electrode terminals, the end plate 5 of the mounting base 1 is the same as in FIGS. There is a configuration in which the electrode terminal 6 is disposed. Further, as another configuration, as shown in FIGS. 9 to 11, by using a flat plate-shaped power wiring 14 ′ and attaching each dedicated joint 16, 17, 18 to the terminal portion of the mounting base 1, The thing which electrically connects the two attachment bases 1 is mention | raise | lifted. In the example shown in FIG. 9, the power wiring 14 ′ is arranged on the bottom surface of the mounting base 1, in the example shown in FIG. 10, the power wiring 14 ′ is arranged on the side surface of the mounting base 1, and in the example shown in FIG. A power wiring 14 ′ is erected inside the mounting base 1. Then, the flat power wirings 14 ′ of the two mounting bases 1, 1 are electrically connected via the electrical connection parts 20, 21, 22 provided in the respective dedicated joints 16, 17, 18. It has a structure.
