This application claims under 35 U.S.C. § 119(a) the benefit of priority to Korean Patent Application No. 10-2021-0052977 filed on Apr. 23, 2021, the entire contents of which are incorporated herein by reference.
The present disclosure relates to a structure and method for utilizing natural light in an interior of a moving space. More particularly, it relates to a structure and method for utilizing natural light in an interior of a moving space in which the structure and method may control an illumination state so as to be appropriate for a multipurpose indoor space. The structure and method for utilizing natural light in an interior of a moving space may maximally utilize natural light using a natural light condenser and a natural light transmitter and supplement artificial light when the amount of natural light is not sufficient so as to effectively manage power for illumination.
In general, lighting apparatuses are installed in the interior of a vehicle so as to illuminate the interior of the vehicle. The vehicle interior lighting apparatuses generally include a front room lamp, a dome room lamp, reading lamps, etc. Fluorescent lamps or light emitting diodes (LEDs) configured to emit monochromatic light are applied as the conventional vehicle interior lighting apparatuses.
Light emitted by the conventional vehicle interior lighting apparatuses is artificial monochromatic light, and thus bothers passenger eyes. Therefore, various lighting apparatuses, configured to set various lighting environments so as to direct change in more anthropocentric natural illumination in the interior of a vehicle and to selectively control brightness so as to provide these lighting environments, are being developed and applied. For example, brightness of illumination may be selectively adjusted using a dimming function. Further, even in this case, only brightness may be adjusted, but change in natural light is not capable of being directed and illumination is not capable of being adjusted depending on various indoor situations.
Recently, for the convenience of a vehicle user, various sensors and electronic apparatuses tend to be provided in vehicles. Particularly, for user convenience in driving, advanced driver assistance systems (ADASs) are being vigorously researched. Further, autonomous vehicles are being actively developed.
Further, purpose-built vehicles (hereinafter referred to as ‘PBVs’) are emerging as future mobility devices which extend living spaces. For example, when a PBV including a shoe store and a clothing store docks with a hub, the hub becomes a shopping center. The functions of PBVs according to purposes thereof and design extensibility of PBVs are considerable. A PBV is a new type of a mobility device other than public transportation, such as buses, and private vehicles, and is used as a flexible space such that the purpose of a hub varies depending on the purpose of a PBV docking with the hub.
In order to acquire higher utility of such an autonomous vehicle or a PBV, when the autonomous vehicle or the PBV is used for personal purposes or in the service industry, an effective lighting system which is appropriate to a specific situation is required. For example, illumination needs to be adjusted such that natural light is maximally utilized in a situation, such as during resting, in everyday life or indoor plant cultivation, and artificial light is used in a situation, such as during sleeping, watching movies, or refreshing.
As environmental regulations are strengthened and energy cost is reduced around the world, the use of eco-friendly electric vehicles (EVs) has increased. In an electric vehicle, it is necessary to effectively use the power consumed by the overall system of the electric vehicle. As one method for satisfying this, natural light illumination and artificial light illumination may be operated in combination so as to maintain necessary illuminance, thereby being capable of reducing power consumption and supporting stable illumination. Therefore, a lighting system that may control output of artificial light by confirming a degree of condensation of natural light and also control the lighting situation of an indoor space so as to realize a target illuminance is required.

In the determination as to whether or not the camera unit 600 is capable of sensing the current indoor information (S110), the controller 500 may determine whether or not brightness of the interior of the vehicle is sufficient to sense the kind or position of an object or a user. When the camera unit 600 is not capable of sensing the current indoor information, the controller 500 may operate the artificial light generator 340 of the smart lamp unit 300 so as to generate artificial light sufficient to sense the kind or position of the object or the user. When the camera unit 600 is capable of sensing the current indoor information, the controller 500 may analyze the current indoor information sensed by the camera unit 600. The current indoor information may be information about the object or the user currently located in the interior of the vehicle.

When the amount of natural light transmitted by the natural light transmitter 200 is not sufficient to implement the target illuminance, the controller 500 may perform a calculation so as to radiate natural light and artificial light (S320). The controller 500 may transmit a control signal so as to radiate a combination of natural light and artificial light by supplying power to the artificial light generator 340 depending on a result value of the calculation (S330).
The smart lamp unit 300 may receive the control signal from the controller 500 and may selectively adjust the radiation amounts of natural light and artificial light (S340). For example, the smart lamp unit 300 may adjust the amount of natural light input from the natural light transmitter 200 and cut off the natural light. Further, the smart lamp unit 300 may adjust the intensity of artificial light emitted by the artificial light generator 340 or cut off the artificial light.

The controller 500 may determine whether or not the illumination light is radiated to the position value corresponding to the user request signal by sensing the position to which the illumination light is radiated through the camera unit 600 or by recognizing the amount of rotation of the first lamp housing 320. In the determination, by the controller 500, whether or not the illumination light is radiated to the position value corresponding to the user request signal (S410), when the illumination light is not radiated to the position value corresponding to the user request signal, the controller 500 may calculate the amount of movement of the first lamp housing 320 so as to radiate the illumination light to a target position.
The controller 500 may transmit the result value of the calculation for moving the first lamp housing 320 to the smart lamp driver 400. Further, the controller 500 may supply power corresponding to the result value of a calculation to move the first lamp housing 320 to the smart lamp driver 40.
