The illuminator 30 is an illuminator used in a lighting apparatus, and illuminates an intersection by being illuminated by receiving power.

The light diffusing module 40 is disposed on one of the struts 23 of the tower 20, that is, below the illuminator 30, and diffuses light irradiated from the illuminator 30 And is constituted by a fixing plate 41, a light diffusion plate 42, a winding means 43 and a wire 44. The fixing plate 41,

The fixing plate 41 is fixed (welded, clamped, bolted, etc.) to the circumferential surface of the support 23 and supports the optical diffusion plate 42.

The light diffusing plate 42 diffuses the light irradiated from the illuminator 30 to brightly illuminate the intersection. When the illuminating unit 30 can brightly illuminate the light diffusing plate 42, When the intersection can not be brightly illuminated by the light irradiated by the illuminator 30 due to mist or the like, the illuminator 30 is illuminated under the illuminator 30 to brightly illuminate the intersection.

The light diffusing plate 42 may be of a single type, but it is preferable that the main diffuser plate 42-1 and the light diffusing plate 42-1 are provided so as to reduce the loss of light irradiated from the illuminator 30, And vane diffusers 42-2 and 42-3.

The main diffuser plate 42-1 is rectangular, and the vane diffuser plates 42-2 and 42-3 have a structure in which one side overlaps the main diffuser plate 42-1, for example, a fan shape. According to the structure, since the wing diffuser plates 42-20 and 42-3 are spread out and spread out from the main diffuser plate 42-1, the main diffuser plate 42-1 and the wing diffuser plates 42-2 and 42-3 ) Is capable of providing the maximum light diffusing surface in the unfolded state and reducing the volume in the folded state of the tower 20.

The main diffusion plate 42-1 and the blade diffusion plate 42-2 are hinged to the fixing plate 41 at the bottom.

It is preferable that the main diffusion plate 42-1 and the wing diffusion plates 42-2 and 42-3 are hinge-connected so as to be unfolded by their own weight without being spread by an external force. In addition, (The direction away from the tower 20) of the main diffusion plate 42-1 is provided between the diffusion plate 42-1 (or the wing diffusion plates 42-2 and 42-3) The light diffusion plate 42 can be unfolded naturally by the application of a member (leaf spring or the like).

The light diffusing plate 42 is not used when the light irradiated from the illuminator 30 illuminates the intersection brightly, that is, when the light is irradiated from the illuminator 30, If not transmitted to the intersection, unfolds at an angle from the tower 20 at an angle to diffuse the light of the illuminator 30 towards the intersection.

Therefore, the winding motor 43-1 is controlled so that the light diffusion plate 42 is inclined with respect to the illuminator 30 when the illuminance value by the illuminance sensor is not more than the reference illuminance value.

The illuminance sensor can be installed at various positions such as the fixing plate 41 of the optical diffusion module 40.

1. Normally (current illumination is higher than reference illumination)

The light diffusion module 40 is housed so as not to protrude from the strut 23 in close contact with the strut 23 of the tower 20. [

The illuminator 30 is powered on and irradiates light to illuminate the intersection through the light.

2. Under the reference illumination.

When the current illuminance is less than the reference illuminance, the controller determines that the light of the illuminator 30 can not be transmitted to illuminate the intersection, . ≪ / RTI >

The winding motor 43-1 of the winding means 43 is activated by the control of the controller and the winding drum 43-2 is rotated by the rotational force of the winding motor 43-1, (42) is rotated and unfolded. The light diffusing plate 42 is smoothly spread by its own weight. In addition, when the elastic member is applied, the light diffusion plate 42 is smoothly unfolded from the tower 20.

When the main diffusion plate 42-1 and the wing diffusion plate 42-2 are unfolded, the wing diffusion plate 42-2 is extended from the main diffusion plate 42 -1) so that the light diffusing surface is widened.

If the current illuminance value sensed by the illuminance sensor satisfies the reference illuminance value in this state, the winding motor 43-1 is driven to rotate in the reverse direction to wind the wire 44. By winding the wire 44 The light diffusing plate 42 is folded toward the tower 20. At this time, due to the elastic force of the coil springs 42-4 and 42-5, the vane diffuser plates 42-2 and 42-3 are gathered toward the main diffuser plate 42-1.

Meanwhile, the present invention is configured as follows to set the optical diffusion plate 42 at an optimum position suitable for illumination through the height adjustment.
