In addition, in the present specification, the outdoor light includes a street light installed on a road or a pedestrian road and a lighting or security light installed at a place such as a park or a playground. In other words, the outdoor light includes all the lights installed outdoors for lighting.

Although the reflection shade is described herein on the premise of being hemispherical or semi-elliptic spherical, this is exemplary and the present invention is not limited thereto. In addition, for convenience of explanation, the concept of long axis and short axis is used, and long axis and short axis are used in the same meaning as the long axis and short axis of the ellipse. If not an ellipse, an ellipse is assumed to mean a straight line corresponding to a short axis and a long axis. For example, in the case of being generally rectangular, one of the bisectors perpendicular to each other may be the long axis and the other may be the short axis.

Referring to FIG. 1C, the reflection shade may be hemispherical as a whole, with a diffuser or reflecting surface installed inside and a protective cover installed outside. Specifically, the outer surface may be formed of the protective surface (L, R) and the rim surface (C) formed on both sides of the ceiling surface (P), ceiling surface (P).

Referring to FIG. 1A, the inner surface may be hemispherical as a whole but is not limited thereto and may be, for example, a polyhedron. The inner surface may have a function of reflecting or diffusing light emitted from the light source and may be composed of a diffused ceiling surface 11, reflective side surfaces 12a and 12b, a reflective front surface 13 and a light emitting rear surface 14. If necessary, guide surfaces 15a and 15b may be formed at the ends of the reflective front surface 13 or the light emitting rear surface 14.

The radius of curvature of the diffused ceiling surface 11, the radius of curvature of the reflective side surfaces 12a and 12b, the reflective front surface 13 and the light emitting back surface 14 may be different from each other, and the radius of curvature of the reflective side surfaces 12a and 12b may likewise be different. It may be different and preferably the radius of curvature of the diffusion ceiling surface 11 may be smaller than others.

Reflecting pieces 111, 121, 131, 141 may be arranged in a matrix structure on each reflecting surface, and each matrix structure may be different from each other, and also the geometry of each reflecting piece 111, 121, 131, 141 May be different. In the present specification, the matrix structure means that the reflection pieces 111, 121, 131, and 141 are arranged in rows and columns, and the inductive matrix structure indicates that each reflection piece 111, 121, 131, and 141 in the matrix structure specifies light.

The diffused ceiling surface 11 may have a polygonal shape as a whole and the reflective piece 111 may have a symmetrical structure with respect to the longitudinal direction. In the present specification, the longitudinal direction means a radial direction in a specific direction, and means a long axis direction or a short axis direction when the reflection shade becomes an elliptical sphere as a whole. If it is spherical means a radial direction passing through the light source socket (E). The edge surface of the diffusion ceiling surface 11 has a curved shape, but this curved shape is due to the reflection shade 10 itself becoming spherical.

One edge of the reflective side 12a, 12b may each have a shape corresponding to the edge of the opposing diffused ceiling surface 11 and the other edge is curved or corresponds to the rim of the reflective shade 10.

The reflective piece 131 may extend in the longitudinal direction corresponding to the long axis of the ellipse, and the inclination angles of both sides of the triangular pyramid may be symmetrical or asymmetrical. In case of asymmetry, the outside of the shaft forms a small inclination angle around the long axis and the inside of the shaft forms a large inclination angle. Such a structure prevents light from being emitted to the outside and at the same time improves optical properties.

The induction surfaces 15a and 15b may be formed integrally with the reflective front surface 13 or the light emitting rear surface 14 or may have an independent structure. The integrally formed means that the shapes of the reflective pieces are the same or similar, and that the shapes of the reflective pieces are formed by different optical and geometric structures means that the reflective pieces have different shapes. In the present specification, the term optical means a reflection angle, a reflection path or a reflectance. Further, for example, the term optical may include such as surface roughness. The induction faces 15a and 15b may be selectively installed in consideration of the power of the light source or the illumination area. For example, if the degree of reflection from the reflective front surface 13 is not sufficient, the direction of reflection bias can be appropriately adjusted while forming the guide surface 13b to have a larger inclination angle than the reflective front surface 13. Although not shown in FIG. 1A, induction surfaces may also be formed on the reflective sides 12a, 12b. The induction plane is intended to re-adjust the reflection amount of the light source, which is primarily adjusted in this way, and may be mainly formed at the end of the reflection plane in each direction. Reflective surfaces can be formed in various structures or locations and the invention is not limited to the embodiments presented.
