A plurality of light sources and a control unit for controlling the light emission state of the light sources, wherein each of the light sources emits light in a different color toward a different direction. As the natural force, for example, sunlight is used.

According to the present invention, each light source emits a different color in a different direction. Therefore, when the viewer walks so as to cross the band of light emitted from each light source, You can experience the scenery of changing colors.
In addition, if this device is installed side by side on the riverbank and the control contents for repeatedly performing the soft-on process of gradually increasing the light from each light source and the soft-off process of gradually decreasing the light are set in the control unit, With the lighting of various colors emitted from the light source, it is possible to produce a fantastic atmosphere reminiscent of fireflies, and as a result, it is possible to realize colorful landscape lighting.
Further, in the present invention, the light source is turned on individually by a self-light-emitting method that uses a power generation unit that generates power from light received from the outside and a power storage unit that stores electric power supplied from the power generation unit. With this configuration, no special wiring work is required for this apparatus, and the installation can be performed easily.
Also, a plurality of light sources are arranged so that the optical axes of the light emitted radially from each light source are located on the same plane, and the radiation angle of the light from the light source with respect to the ground is adjusted by an adjusting mechanism for adjusting the angle of the fastening means By adjusting according to the above, it becomes possible to optimally emit light according to the viewing height of the viewer.
In addition, when a brightness sensor for detecting the brightness of outside light is provided, and the brightness of the outside light detected by the brightness sensor in the control unit falls below a preset reference value, If the light source is automatically turned on and set to be turned off after a certain time from the start of light emission, the device can be driven within an appropriate time, and an excessive load can be prevented from being applied to the device.
In addition, the light source is configured so that color elements such as violet, blue, green, orange, and yellow are positioned around the white element, and the light source emits light corresponding to the position viewed by the viewer.

An embodiment of the present invention will be described with reference to FIGS.
1A to 4 show a plan view, a front view, a side view, and a cross-sectional view of a self-luminous lighting device 100 according to the present invention, respectively. In these drawings, reference numeral 1 denotes a housing serving as a main body case. Showing the body.
The housing 1 includes a base member 2 that is in direct contact with the ground G or the concrete C on the ground G, and a cover member 3 that covers the edge of the base member 2.

  On the base member 2 of the housing 1, the power generation unit 4 that generates power by external light, the power storage unit 5 that stores power generated by the power generation unit 4, and the power supplied from the power storage unit 5 are driven. A plurality of light sources 6 and a control unit 7 for controlling the light emission state of these light sources 6 are accommodated.

The power generation unit 4 is constituted by a solar panel, and a plurality of power generation units 4 are arranged at the center of the housing 1 as shown in FIG. In addition, it may replace with the solar panel of this embodiment, and you may make it use the electric power generation means to generate electric power by natural forces, such as a wind force and hydraulic power. In particular, when it is arranged along a riverbank or coastline, power may be supplied from power generation means using river water flow, seawater wave, or the like.
The power storage unit 5 is disposed below the power generation unit 4 and is configured by a secondary battery such as a lithium battery or a capacitor such as a capacitor.

The light source 6 is a light emitting element composed of an LED, and is arranged in a plurality of arcs along one edge of the housing 1 and emits emitted light radially outward.
Further, as shown in FIG. 1A, the light source 6 is configured so that the color elements 6C to 6F such as violet, blue, green, orange and yellow are positioned around the white elements 6A and 6B. The light emitting elements composed of the white elements 6A and 6B and the color elements 6C to 6F are richly colored by adjusting in advance the light emission angle and the color mixture range where the light overlaps according to the position viewed by the viewer. Realize landscape lighting.

Further, the light emitting elements comprising the white elements 6A and 6B and the color elements 6C to 6F constituting the light source 6 are adjusted so that the optical axes 6a to 6f of the light emitted radially from the light sources 6 are in the same plane. When the viewer walks so as to cross the band 10 of light emitted from each light source 6 (around the optical axes 6a to 6f) by such position adjustment, the viewer can change variously. You can experience a landscape where the color of the light changes (see FIGS. 7 and 8).
In this example, as the color elements 6C to 6F, in addition to the combination of “violet”, “light blue”, “green”, “blue”, “orange”, “yellow”, “pink”, “red” A combination is adopted.

Further, as shown in the block diagrams of FIGS. 1A and 1B, a brightness sensor 11 for detecting the light intensity of external light is connected to the control unit 7.
Then, the control unit 7 starts light emission of the light source 6 and emits light by measurement with the built-in timer 7A when the brightness of the external light detected by the brightness sensor 11 falls below a preset reference value. Light emission / extinguishment control is performed so that the light is extinguished after a preset lighting time (for example, 5 hours) from the start time. Instead of using the timer 7A, the amount of power stored in the power storage unit 5 may be left to be turned off naturally by a decrease in the output power or by the control of the control unit 7 by detecting a power decrease. .

  In the control unit 7, the single color white elements 6 </ b> A and 6 </ b> B and the color elements 6 </ b> C to 6 </ b> F constituting the light source 6 are caused to blink. However, the present invention is not limited to this. May be used to repeatedly perform a soft-on process of gradually increasing brightness and a soft-off process of gradually decreasing dark while changing the color in each light emitting element.

  Further, the light-off control as described above is not limited to using the timer 7A of the control unit 7, but may be performed by adjusting in advance the capacity of the power storage unit 5 that stores electric power. That is, if it is desired to set the lighting time from the start of light emission of the light source 6 to be short, the small-capacity power storage unit 5 is used. The power storage unit 5 may be used.

At the same time, the size of the power generation unit 4 serving as a solar panel may be determined according to the light receiving efficiency of external light (mainly sunlight).
Specifically, when the sunlight cannot be received sufficiently (in the shade of trees, etc., or at a large oblique angle with respect to sunlight), the area of the power generation unit 4 is set large, When sunlight can be sufficiently received (not shaded by trees or the like, or at a right angle to sunlight or an angle close thereto), the area of the power generation unit 4 may be set small.
