By integrating the camera, the control device, and the lighting device, it is possible to provide an LED lighting apparatus that can be installed at any place and can automatically control the lighting.

  The backbone 2 is a substantially circular steel plate component, and has a mounting hole 2a for locking a mounting adapter (not shown) at the center.

  The insulating plate 3 is made of a constituent resin having flame retardancy and electrical insulation, and is fixed to the backbone 2 with screws. Further, the insulating plate 3 has a cylindrical projection 3a for fixing the LED lighting device 1 to a ceiling surface or a predetermined position and connecting to the mounting adapter.

The power supply substrate 4 has a lighting circuit including a control unit, and is screwed to the backbone 2 via an insulating plate 3. By using the insulating plate 3, it is arranged in a state in which electrical insulation is maintained.
Further, the power supply board 4 is electrically connected to the mounting adapter via an electric wire (not shown). Similarly, it is electrically connected to the LED light source substrate 6 and the camera unit 10 via electric wires. Thereby, it is possible to control the way of light such as the brightness of light emitted from the LED light source substrate 6.

  The heat radiating plate 5 is a substantially circular steel plate component, and has a through hole 5a corresponding to the backbone 2 and the mounting hole 2a of the insulating plate 3 and the cylindrical projection 3a at the center. A screw hole is provided at a symmetrical position with the through hole as a center, and the insulating plate 3 is screwed and fixed through the hole. Moreover, the heat sink 5 has a convex portion in a trapezoidal shape toward the central portion, and by attaching the LED light source substrate 6 to this convex portion, the heat of the LED light source substrate 6 is radiated and cooled.

The LED light source substrate 6 has a plurality of LED elements in a plurality of rows on the circumference. The LED element has a daylight color LED, a light bulb color LED, and a blue-green LED. The daylight color LED emits daylight color light with a peak wavelength of 430 to 460 nm, the light bulb color LED emits light bulb color light with a peak wavelength of 550 nm to 650 nm, and the blue-green LED emits blue light with a peak wavelength of 470 nm to 500 nm. To do.
The LED light source substrate 6 is connected to the power supply substrate 4 by an electric wire, and is controlled to control light emission from the power supply substrate 4, for example, lighting, extinction, and light adjustment and color adjustment by adjusting a current value.

  The LED cover 7 has a circular plate surface, and the plate surface has a plurality of convex portions having a lens function corresponding to the arrangement of the LED elements. In addition, the side surface of the circular plate surface has a cylindrical wall surface and plays a role of insulation from the LED light source substrate 6. The outer peripheral part of the cylindrical wall surface has a convex part, and is fixed to the heat radiating plate 5 with screws through the convex part. The LED cover 7 has a screw hole on the circumference located at the center of the outer diameter and inner diameter of the plate surface portion, and is fastened together with the LED light source substrate 6 to the heat radiating plate 5 by screws.

  The center cover 8 has a structure that can be attached and detached by fitting in the central rib of the LED cover 7 and rotating in the radial direction. The color of the center cover 8 is white, which has the effect of increasing the reflectivity and reducing the darkness at the center of the appliance when it is lit.

  The shade 9 is fitted in the concave portion of the heat radiating plate 5 and rotated in the radial direction, so that the convex portion of the shade 9 is fitted with a receiver (not shown) and is detachably attached. The shade 9 has an effect of diffusing light, and has an effect of reducing glare and spreading light uniformly in a space.

  As shown in FIG. 4, the camera unit 10 includes a camera lens unit 10a, a camera driving unit 10b, and a case unit 10c that houses the camera lens unit 10a and the camera driving unit 10b, and has a camera function. In this embodiment, the camera unit 10 is located outside the backbone 2, the heat sink 5, and the shade 9. In the camera unit 10, a part of the case portion 10 c is located on the ceiling side (upper surface side) of the heat radiating plate 5 and is fixed to the heat radiating portion 5 with screws. That is, the same thing as the shade, backbone, or LED light source substrate of the LED illumination device that does not use the camera unit 10 can be used. The camera unit 10 acquires an image through the camera lens unit, and recognizes a person based on the acquired image. The camera driving unit 10b can be moved in any direction, and the direction in which the camera lens unit faces can be arbitrarily changed.

FIG. 5 shows an example of the camera recognition range when the LED lighting device 1 is viewed from the side. The angle θ of the camera recognition range shown in FIG. 5 is not particularly limited. By moving the camera driving unit 10b, it becomes possible to arbitrarily change the recognition range by the camera as shown in FIG. 5, for example, when the camera is directed toward the entrance of the room and recognized when a person enters the room. A desired usage method can be easily realized by adjusting the range and changing the recognized distance or position.
FIG. 6 shows an example in which the camera drive unit is moved leftward in FIG. 5 and the camera recognition range is changed to the recognition range I. Similarly, FIG. 7 shows an example in which the camera driving unit is moved rightward in FIG. 5 to change the camera recognition range to the recognition range II. In addition, in FIG. 5, the camera drive unit can be moved not only in the left-right direction but also in the front direction and the back direction, and the camera recognition range can be changed in the entire circumferential direction of the LED lighting device 1. Thereby, regardless of the installation location of the LED lighting device 1, a function by the camera unit 10 in a desired recognition range and recognition position, for example, an image is captured from the camera unit 10, and the presence / absence of a person in a room or individual recognition of a person is performed, Automatic dimming and automatic lighting with any light can be realized. When there is no person, power consumption can be suppressed by dimming the illumination. Further, when entering a room, a person is individually recognized and is lit with an arbitrary light set by each person, so that it is possible to save time and effort for setting lighting such as arbitrary dimming and toning.

  The present invention is not limited to the above-described embodiment, and various modifications and changes can be made within the scope of the technical idea, and the present invention extends to these modifications and changes. Of course. For example, although the embodiment has a camera unit outside the shade, it may be inside the shade or the instrument body.
