On the other hand, the outer size of the light reflecting passage 30 will be described further, the second passage 34 is formed in the lower portion wider than the upper portion to have a sense of stability exposed to the outdoors. Since the first passage 32 of the light reflection passage 30 is coupled to the structure, the first passage 32 has a lower shape and a lower shape. The first passage 32 of the light reflection passage 30 has a cylindrical shape having an upper diameter and a lower diameter, and the second passage 34 of the light reflection passage 30 has an upper diameter at the lower portion thereof.

Support structure.

The diameter of the second light processor 20 increases as the distance from the boundary surface increases. That is, the diameter has a shape that is gradually wider from the upper side to the lower side so that the light transmitted to the room through the second light processing unit 20 can be diffused into a wider space of the room. Here, the upper side of the second light processor 20 refers to a portion near the boundary surface. The shape of the second light processor 20 may be formed in various shapes in consideration of the fact that sunlight and artificial light may be used as room lighting.

The first light transmissive cover 14 faces the first light transmissive cover 14 in one direction. That is, the first light transmissive cover 14 is formed such that the convex portion in FIG. 2 faces upward. The first light transmission cover 14 functions as a transparent window through which sunlight is incident.

The first light irradiation cover 16 faces a direction different from one direction. That is, the first light irradiation cover 16 is formed such that the convex portion in FIG. 2 faces downward. The first light irradiation cover 16 is formed in a ring shape.

The second light processor 20 includes a second light irradiation cover 22, a reflector 24, and a second light emitter 26. The second light irradiation cover 22 is formed so that the light to be irradiated is directed toward the room. Therefore, most of the light is directed to the room, and some light may pass through the second light-illuminated cover 22 to be reflected on the wall to be directed back to the room. If necessary, the third transmissive cover may be coated with a separate coating or may be replaced with a non-transparent cover to prevent light from being transmitted to the outer surface.

The reflecting plate 24 is mounted on the second light irradiation type cover 22 to partition the plurality of spaces, and diffuse the light irradiated into the room to a larger space in the room. The reflecting plate 24 is formed in a thin plate shape and may be formed of an aluminum material.

As shown in FIG. 2, the lighting apparatus 100 according to the embodiment of the present invention further includes a storage battery 40, a controller 50, a controller, an optical sensor 42, and a switch 44. . The storage battery 40 is electrically connected between the solar cell 12, the first light emitter 18, and the second light emitter 26 to store electrical energy generated by the solar cell 12.

For example, the controller 50 may be configured as a kind of microprocessor, and is electrically connected between the battery 40 and the first light emitter 18 and the second light emitter 26 to control the flow of electrical energy.

By using the optical sensor 42, the corresponding light-emitting body can be turned off in a state where illumination is unnecessary, such as during the day.

The controller 50 analyzes an illuminance detection signal input from the optical sensor 42 and supplies electrical energy to the first light emitter 18 and the second light emitter 26 when the illuminance is less than the set illuminance. Accordingly, the first illuminant 18 and the second illuminator are automatically detected by comparing the illuminance around the first light processor 10 with the light sensor 42 and comparing the illuminance set by the control unit 50 with the input illuminance. The light emitter 26 can be turned on and off automatically.

The switch 44 is electrically connected to the control unit 50 to control the flow of electrical energy supplied to the first light emitter 18 and the second light emitter 26 as it is turned on / off. Therefore, the user can turn on and off the first light emitter 18 and the second light emitter 26 by turning on / off the switch 44 as necessary.

4 is a view showing the day utilization of the lighting device 100 according to an embodiment of the present invention, Figure 5 is a view showing the night utilization of the lighting device 100 according to an embodiment of the present invention.

Referring to FIG. 4, when the lighting device 100 is used during the day, solar energy 12 is converted into electrical energy in the solar cell 12 in which sunlight is collected. Outdoor sunlight is introduced into the room through the light reflection path 30 through the first light transmissive cover 14. If necessary, the electrical energy generated by the solar cell 12 is stored in the storage battery 40. The electrical energy generated by the solar cell 12 or stored in the storage battery 40 may be used on a cloudy day or at night when there is no sun, and illuminates the surroundings through the first and second light emitters 18 and 26. .

The first light emitter 18 positioned at the upper portion may be irradiated downward and the light irradiated upward may be irradiated to the outside by the light of the basement layer. In addition, the second light emitter 26 disposed below is irradiated downward, and some light may be irradiated to the outside along the light reflection path 30.

In general, it is difficult to access sunlight, which is natural light, for buildings and underground facilities, and thus, relies on lighting devices such as fluorescent lamps. Artificial light, which is an artificially made light such as a fluorescent lamp, may have a different color depending on a lighting device, unlike sunlight, which is natural light. And artificial light does not have ultraviolet light that has a bactericidal action. Therefore, if necessary, special special lighting facilities or UV generators should be installed.

In addition, artificial light consumes extra energy, which is a factor in waste of resources. Therefore, in order to deliver energy saving and natural light characteristics to the underground space or inside the building, a lighting device that can properly transmit sunlight to the interior is required.

On the other hand, the most important thing in transmitting outdoor sunlight to the indoor is how to transmit the strong straight light. And since the sun changes its position due to the rotation of the earth, it cannot supply a certain amount of sunlight indoors.

In order to use sunlight as a power source, a solar cell 12 is configured to convert solar energy into electrical energy to generate a required voltage. If the generated voltage of the solar cell 12 is lower than the required voltage, the solar cell 12 may be used as a solar cell module by arranging a plurality of solar cells 12 in series.

The lighting device 100 according to the embodiment of the present invention stores the power through the solar cell 12 while irradiating sunlight indoors during the day, and the first light emitter 18 stores the power stored in the solar cell 12 at night. Or the second light emitter 26 is irradiated with light indoors and outdoors.

For example, when the lighting device 100 is used during the day, outdoor light and indoor light may be communicated with each other through the light reflection path 30 to transmit sunlight to the room to irradiate light to the room. In contrast, when the lighting device 100 is used at night, light stored in the solar cell 12 may be supplied to the first light emitter 18 or the second light emitter 26 to irradiate light outdoors and indoors. .

Meanwhile, the lighting device 100 according to the embodiment of the present invention may further include a power supply unit (not shown) electrically connected to the storage battery 40, and the first light processing unit 10 through the power supply unit and the storage battery 40. ) And the first light emitter 18 and the second light emitter 26 provided in the second light processor 20, respectively. Here, the power supply unit may use a home power supply.
