In this case, the LED 268 (see FIG. 21) is installed at the rear end of the petal-shaped opening and closing plate 271, and the petal-shaped opening and closing plate 271 is made of a material capable of transmitting the light emitted from the LED to the entire panel. . In addition, in order to diversify the light emitted through a plurality of petal-shaped opening and closing plate 271, the LED can be configured to implement a variety of colors, such as RGB, these LEDs are ON / OFF time by the control of the control computer It can be configured to generate more colorful and diverse light while being adjusted.

On the other hand, the above-described configuration using the LED mainly in the lighting unit 260, but not necessarily limited to the LED, it can be configured using a variety of known emitters as long as it can emit light.

Next, the opening and closing portion 270 is configured similarly to the opening and closing portion 270 of the second embodiment described above, and basically rotates around the rotational support portion in accordance with the operation of the opening and closing drive mechanism 280, centering on the main lamp 261. It is configured to open and close with.

The opening and closing part 270 may be configured as a double petal structure, the petal-shaped opening and closing plate 271A constituting the inner petal inside, and the petal-shaped opening and closing plate 271B constituting the outer petal from the outside. have.

The opening and closing operation of the double petal structure will be described in detail while explaining the opening and closing drive mechanism 280.

Next, the opening and closing drive mechanism 280 is configured to generate the opening and closing force to open and close the petal-shaped opening and closing plate 271 as described above, largely due to the rotational force of the electric motor 281, the electric motor 281. The shaft 284 and the cam mechanism 285 which rotate together by this, and the interlocking lever 288 which operate the petal type opening-and-closing plate 271 while rotating by this cam mechanism 285 are comprised.

The electric motor 281 may generate a rotational power, and may use a DC geared motor capable of decelerating.

The shaft 284 is a part that is coupled to the rotation shaft 282 of the electric motor 281 and rotates together, and has a structure that protrudes forwardly.

The cam mechanism 285 is configured by pairing two cams 285A and 285B to drive the inner petal opening and closing plate 271A and the outer petal opening and closing plate 271B, respectively, as shown in the drawing. It is coupled to the shaft 284 at spaced apart locations and configured to rotate with the shaft 284.

This cam mechanism 285 is formed with a cam profile so that each cam 285A and 285B can open and close three petal-shaped opening and closing plates 271 in this embodiment. When the interlocking lever 288 contacts the top dead center of the cam profile, the petal open / close boards 271 are opened, and when the interlock lever 288 contacts the bottom dead center, the petal open / close boards 271 are configured to be closed.

The pair of cams 285A and 285B have a spacer 286 interposed therebetween, and the front first cam 285A, the spacer 286, and the second cam 285B so that they can rotate together in the same manner. This screw has a structure that is integrally assembled.
The linkage lever 288 is installed in a state rotatably supported by the lever pin 288a in a state of being installed to pass through the lever hole 215 of the first body 211. In addition, the elastic member 289 having a coil spring structure is provided on the lever pin 288a side of the interlocking lever 288 to provide a force in the direction in which the petal-shaped opening and closing plate 271 is always closed.
For reference, in a hinge device such as a door, a well-known general method for implementing a rotating element to be closed automatically is to install a coil spring on the hinge shaft, and both ends of the coil spring and the rotating element and the rotating element ( Or hinge shafts), respectively, to store the elastic force in the coil spring when the rotating element rotates in one (open) direction by external force, and then rotate by the restoring elastic force of the coil spring when the external force is removed. The method is used to configure the element to rotate in the other (closed) direction.
Also in the present embodiment as a method for providing a force in the direction in which the petal-shaped opening and closing plate 271 is always closed by using the elastic member 289 having a coil spring structure, referring to Figure 24, etc., the elastic member 289 Is wound around the lever pin 288a in a coil spring structure, the both ends of which are coupled to a rotating element such as the interlocking lever 288 and a fixing element such as the lever support 216, so that the petal-shaped opening and closing plate 271 is always It can be configured to provide an elastic force in the closing direction. In order for the elastic member 289 to provide elastic force in the direction in which the petal-shaped opening and closing plate 271 is always closed between the linkage lever 288 and the lever support 216, a rotating element such as the linkage lever 288 and the lever support 216 are provided. It should be very natural to be supported or coupled to a fixed element, such as), the specific coupling structure will be easily implemented by those skilled in the art using a well-known general method, more specific drawings and detailed description thereof will be omitted. do.

On the other hand, the interlocking levers 288 are each in close contact with the respective cams 285A and 285B around the respective lever pins 288a, and the other ones are fixed to the petal-shaped opening and closing plates 271. The bearing 288b (see FIG. 27) may be installed at a portion in close contact with the 285A) 285B to minimize the frictional force.

In addition, the opposite side of the interlock lever 288 is preferably formed in a 'Y' shaped split structure is configured so that the petal-shaped opening and closing plate 271 can be stably assembled and supported.

In the lighting apparatus of the third embodiment according to the present invention as described above, the petal opening and closing plate 271 can be opened and closed by rotating the interlocking lever while the cam mechanism rotates according to the operation of the electric motor.

On the other hand, the lighting installation (P) may be provided with a peripheral sensor 290 (see Fig. 21) to check whether there are people or moving objects around the lighting fixture. In addition, it is also possible to install the ambient sensor in the lamp post or lighting fixtures as well as the lighting installation (P).

In the case of installing the ambient sensor 290, when a person or a moving object enters the area where the luminaire is installed, it is configured to detect and automatically open the petal-shaped opening and closing plates 271, and the person or moving object. When the distance is far away can be configured to close the petal-shaped opening and closing plate (271). This is one example using a sensor, it can be configured to adjust the opening and closing time and the degree of opening and closing of the petal-shaped opening and closing plate 271 according to the implementation conditions.

In addition, when the petal-shaped opening and closing plate 271 is opened, the main lamp 261 is turned on for a predetermined time to illuminate the surroundings, and when the petal-shaped opening and closing plate 271 is closed, the main lamp 261 is closed to the main lamp 261 as needed. Only the LED 268 provided in the installed LED 266 or the petal-shaped opening and closing plate 271 may be configured to be turned on. In this case, the LEDs 266 and 268 may be configured to be controlled to generate illumination light of various colors through RGB color implementation.

For the control operation of such a luminaire, it is preferable that the control unit is configured together with the luminaire of the present invention. The control unit may be configured in the body portion, but may be configured externally, such as a street lamp post, or may be configured to be integrated control when a plurality of lighting fixtures are installed. When the control unit is configured in the luminaire or the structure in which the luminaire is installed, it is also possible to perform a wireless control using a remote controller or the like.
