That is, in the height direction of the LED lamp main body 1, a part of the LED substrate 15 overlaps with the lighting device 13 and is positioned below the lighting device 13 in a state where the LED lamp main body 10 is attached to the ceiling surface 7. Yes. Thereby, space saving can be achieved, ensuring sufficient heat dissipation effect by the board | substrate fixation 14th. That is, since the heat can be radiated without arranging the entire LED board 15 outside the lighting device 13, space saving can be achieved.

In this case, as shown in FIG. 4, a cutout 18 is formed in the LED substrate 15 so as to avoid a tall electronic component such as a capacitor 19 or a transformer mounted on the lighting substrate 13. ing. Thereby, the inclination angle of the LED substrate 15 disposed so as to be inclined toward the front side from the peripheral edge portion 10a of the base member 10 toward the center portion can be reduced, and the space-saving LED that can illuminate widely and uniformly. A lighting device can be realized.

Moreover, by providing the notch 18 in the LED board 15, the area of the LED board 15 in the LED lighting device 100 can be increased, and the reflection area of the LED element emitted light by the LED board 15 can be increased. Thereby, the reflection efficiency of LED element emitted light increases, and the efficiency of the LED lighting apparatus 100 increases.

In the illustrated embodiment, similar notches 18 are formed in all LED substrates 15 as shown in FIG. By examining the arrangement of the electronic components of the lighting substrate 13 in advance in accordance with the notches 18 of the LED substrate 15, it is possible to obtain the LED substrate 15 in which the notch positions of the LED substrate 15 are unified, thereby reducing the types of substrates.

In the illustrated embodiment, the LED substrate 15 is fixed to the substrate fixing base 14 and tilted. However, the present invention is not limited to this, and the LED substrate 15 is attached to the LED substrate 15 itself as a base member. It is also possible to add an auxiliary member that inclines toward the front from the peripheral edge portion 10a toward the center portion so that the LED substrate 15 is directly fixed to the base member 10.

(1.-7 LED element)
Note that various known LEDs can be used as the LED element 16 mounted on the LED substrate 15. In the illustrated embodiment, a high-luminance LED element that emits white light for illumination is used.

(1-8 Assembly of the LED lamp body)
The positional relationship among the base member 10, the lighting substrate 13, the substrate fixing base 14, and the LED substrate 15 constituting the LED lamp main body 1 will be described with reference to FIG. First, as shown in FIG. 11, the lighting substrate 13, the substrate fixing base 14, and the LED substrate 15 are disposed between the peripheral edge portion 10 a of the base member 10 and the attachment extension portion 12. The substrate fixing base 14 is located on the center side located on the back side (the ceiling surface side when the LED lamp body 1 is attached to the ceiling surface 4) by a height (h) from the peripheral edge portion 10a of the base member 10. The base member 10 is disposed so as to incline toward the front from the peripheral edge 10a toward the center. In this case, the distance between the translucent cover 3 and the end portion of the LED substrate 15 can be set longer by disposing the substrate fixing base 14 on the inner peripheral side than the peripheral edge portion 10 a of the base member 10. Become. Thereby, especially when the light-diffusion surface is formed in the translucent cover 3, it becomes possible to illuminate a wide range uniformly so that the emitted light position of the LED element 16 cannot be determined.

On the other hand, as shown in FIGS. 1 to 3, the translucent cover 3 is molded into a circular dome shape having a circular opening at the top using a thermoplastic plastic such as polypropylene (PP). Yes. The translucent cover 3 is attached to the LED lamp body 1 so as to seal the LED lamp body 1 as shown in FIGS. 2 and 11 in particular. Specifically, as shown in FIGS. 2 and 11 in particular, the peripheral portion of the translucent cover 3 and the peripheral portion 10a of the base member 10 are fixed by the peripheral cover 6 so that there is no gap between the end portions. ing.

  Thereby, together with the center cap 4 described later, the space between the base member 10 and the translucent cover 3 is sealed, and the LED element 16 can be protected when the LED lighting device 100 is installed. There is no need to provide a cover for protecting the LED element 16. Since the translucent cover 3 has the function of the cover which protects the LED element 16, it becomes possible to reduce cost. Furthermore, since the space between the base member 10 and the translucent cover 3 is hermetically sealed, an effect of preventing dust, insects and the like from entering the LED lighting device 100 can also be produced.

  As shown in FIG. 1 to FIG. 3 and FIG. 11, the translucent cover 3 is formed by making the translucent cover 3 into a continuous curved surface, or providing the translucent cover 3 with a high-density light diffusion surface. It can be irradiated uniformly over the entire surface by applying a graining process to be formed or adding a diffusing agent to the material.

  As shown in FIGS. 1 to 3 and FIGS. 5 to 11, the translucent cover 3 has a center cap 4 at the center. In the present invention, as shown in FIGS. 5 to 10 in particular, the center switch 4 includes a pull switch unit 43 for turning on or off the LED lighting device 100 and a light receiving unit 44 for receiving a signal from a remote controller. Is provided.

(2-1 Center cap)
As shown in FIGS. 5 to 8, the center cap 4 includes a center cap front cover 41 and a center cap back cover 42 fitted to the center cap front cover 41. A pull switch unit 43 and a light receiving unit 44 are held in a space between the center cap back cover 42.

As shown in FIGS. 5 to 11, the center cap 4 is detachably attached to the translucent cover 3. Specifically, the center cap 4 has a cap connecting portion 41c that protrudes toward the LED lamp main body 1 as shown in FIGS. 5 and 7, while the transparent cap as shown in FIG. The center cap receiving part 5 is fitted over the opening of the protective cover 3 and the attachment extension part 12. The center cap receiving portion 5 fixes the mounting extension portion 12 of the LED lamp main body 1 and the translucent cover 3 so that there is no gap, and a center hole-shaped receiving hole 51 a of the center cap receiving portion 5. The center cap 4 is attached to the translucent cover 3 so as to close the opening of the translucent cover 3 by inserting the cap connecting portion 41c of the center cap 4 and then rotating it toward the small diameter side. Is done. Conversely, the center cap 4 can be removed from the translucent cover 3 by rotating the center cap 4 to the large diameter side.

Thus, since only the center cap 4 can be attached and detached, when a malfunction occurs in the pull switch unit 43 and the light receiving unit 44 mounted on the center cap 4, the entire translucent cover 3 and the LED lamp body 1. Without removing the center cap 4, only the center cap 4 can be removed for repair and replacement. When the center cap 4 is rotated, it can be easily rotated by bringing a fingertip into contact with a plurality of convex rotation operation portions 41 d provided on the center cap front cover 41 of the center cap 4. Become. Thereby, the center cap 4 without a clue such as a gripping part for displacement can be easily attached to and detached from the translucent cover 3. Although the rotation operation unit 41d has a convex shape this time, any shape that can be rotated by a fingertip such as a concave shape may be used.

(2-2-2 Pull switch part)
Further, as shown in FIG. 8 in particular, the pull switch unit 43 is arranged in the center cap 4 to turn on or off the LED lighting device 100, and connected to the pull switch 43a to connect the pull switch 43a.

Every time this pull switch 43a is operated, the operation of lighting-half-light-nightlight-extinguishing is repeated as in the fluorescent lamp illumination device.

In this case, the draw string 45 is disposed in the vicinity of the center of the LED lighting device 100 as shown in FIGS. 1 to 3, 5, and 8. That is, by being provided on the center cap 4 provided at the center of the translucent cover 3, the LED illumination device 100 is disposed near the center. For this reason, it can be used with the same feeling of use as a conventional fluorescent lamp illumination device while achieving energy saving by the LED element 16. More specifically, the pull string 45 is disposed in the vicinity of the cap coupling portion 41 c of the center cap 4. For this reason, the torque generated when the pull string 45 is pulled can be reduced and received by the cap connecting portion 41c, the deformation of the center cap 4 can be suppressed, and at the same time, the strength against pulling can be improved. It can increase durability and reduce the need for maintenance and repairs. That is, in the illustrated embodiment, when a force is applied to the drawstring 45, the force is applied from the center cap 4 to the cap connecting portion 41c, the center cap receiving portion 5, the attachment extending portion 12, the attachment portion 11, and the hooking portion. Since it is transmitted directly and relatively linearly to the sealing body 8 and the rosette 9, there is little deformation and the strength against tension is improved.

  At the same time, the center cap 4 can be detached from the translucent cover 3 by being displaced by the operation of the pull string 45. That is, since the pull string 45 is provided on the center cap 4, it can be used for attaching and detaching the center cap 4, and the pull string 45 is held with the rotation operation unit 41d. By rotating the center cap 4, the cap connecting portion 41 c can be locked and released from the receiving hole 51 a in the shape of a daruma hole. As a result, when the center cap 4 is rotated for attachment or replacement or the like, even if the center cap 4 has no clue such as a gripping part for displacement, power for displacement can be loaded. At the same time, since it is an operation while holding the drawstring 45, the center cap 4 is not accidentally dropped and damaged during work, and the center cap 4 can be attached and detached easily and appropriately. Maintenance can be performed.

(2-3 Light receiver)
On the other hand, the light receiving unit 44 is installed on the light receiving substrate 44a through the light receiving hole 41b of the center cap front cover 41 with a signal for operating the LED lighting device 100 issued from a remote controller for operation (hereinafter abbreviated as a remote controller). Light is received by the light receiving element 44b. The signal is determined by the electronic component 44d mounted on the light receiving substrate 44a, and the signal is sent to the lighting substrate 13 by the signal line 41e and the connector 41f to operate the LED lighting device 100. The operation signal of the pull switch 43a is also sent to the lighting substrate 13 by the signal line 41e and the connector 41f, and the LED lighting device 100 is operated.

The light receiving substrate 44a is also equipped with a channel switch 44c for switching a channel for receiving a signal from the remote controller, and can be switched on the lower surface side of the center cap 4 (LED lamp body 1 side). Yes. This channel switching is provided in order to prevent malfunctions caused by operations of other remote controllers when there is a remote controller using the same frequency in the same room, for example.

In this case, in the present invention, as shown in FIGS. 5 and 8, in particular, the center cap 4 has a step so as to form a space on the surface on the LED lamp body 1 side where the channel switch 44c can be operated. Is provided. Specifically, as shown in FIGS. 5 and 8, the lower surface side of the center cap 4 (LED lamp body 1 side) so that the channel switch 44c mounted on the light receiving substrate 44a can be directly operated from the channel switch hole 42a. The center cap back cover 42 has a step structure in which the light receiving portion 44 is low and the pull switch portion 43 is high.

Thus, since the back side of the center cap 4 provided with the pull switch portion 43 and the light receiving portion 44 has a step structure, the light receiving portion 44 is placed on the upper surface (floor side) of one light receiving substrate 44a. A channel switch 44c for switching the channel of the remote controller is provided on the (ceiling surface 7 side) so that the light receiving unit 44 can receive light from the upper surface of the center cap 4, and the channel switch 44c is connected to the lower surface of the center cap 4 (ceiling surface 7 side).
