TECHNICAL FIELD Embodiments of the present disclosure relate to a lighting apparatus and a mobile vehicle including the same. BACKGROUND In general, a vehicular headlamp is provided to a front side of a vehicle to assist in securing a driver's line of sight by emitting light in front of the vehicle. The headlamp may provide high beam and low beam according to driver manipulation. Here, the headlamp is required to emit a suitable quantity of light within a suitable range so as to satisfy the purpose thereof upon emission of high beam and low beam. The headlamp is required to have a design within the range capable of satisfying the above purpose. Therefore, there is a need for a novel lighting apparatus structure that has a high degree of design freedom while performing a desired illumination function. SUMMARY Embodiments of the present disclosure provide a lighting apparatus having a small size and a high degree of design freedom.

In at least one variant, the reflective surfaces of the multiple reflective plates may have different shapes of aspherical surfaces. In another variant, the multiple reflective plates may be continuously arranged in a matrix having columns extending in a first direction and rows extending in a second direction perpendicular to the first direction. In another variant, the multiple reflective plates may include at least one central reflective plate disposed on an imaginary line extending from the first light source in the second direction, and the central reflective plate may have a greater width than other reflective plates excluding the central reflective plate in the first direction. In another variant, the reflective plates arranged in the same column in the first direction may have a symmetrical shape with reference to the central reflective plate disposed in the column. In another variant, at least one of the reflective plates arranged in the same row in the second direction may have a different width than other reflective plates arranged in the row. In another variant, among the reflective plates arranged in the same row in the second direction, the reflective plate separated farthest from the first light source may have a narrower width than other reflective plates arranged in the row in the second direction. In another variant, among the reflective plates arranged in the same row in the second direction, the reflective plate separated farthest from the first light source may have a reflective surface parallel to the support in at least some region. In another variant, the reflective plates arranged in the same row in the second direction may have reflective surfaces with different shapes. In another variant, the multiple reflective plates may be arranged in a step shape in which distal ends of the multiple reflective plates have different heights. In another variant, the first light source and the second light source may be disposed on the same plane of the support. In another variant, the shortest distance between the first light source and the reflector may be less than the shortest distance between the second light source and the reflector. In another variant, a distance between a center of the first light source and a center of the second light source may range from 0.8 mm to 1.2 mm. In another variant, the first light source and the second light source may be independently controlled. In another variant, each of the first light source and the second light source may be included in plural in the light source unit. In another variant, each of the light so
