Referring to FIG. 1A, a perspective view of a curved luminaire 100 in the present embodiment is shown. The curved luminaire 100 includes a light source 102 and a transparent substrate 104. To generate an illumination ray 106. In one embodiment, the light source 102 is one of a light emitting diode (LED) or a light tube.

The transparent substrate 104 has a planar area 110, a surface area 112 on the opposite side of the planar area 110, at least a first side surface 114 between the planar area 110 and the surface area 112, and a planar area 110, At least one second side 116 between the surface area 112 and the at least one first side surface 114, the light source 102 is disposed on the at least one second side 116, and the illumination light 106 enters the at least one second side 116. When the interior of the transparent substrate 104 penetrates the planar region 110 and the surface region 112 to the outside of the transparent substrate 104, the surface region 112 reflects a portion of the illumination light 118a and passes out to the outside of the planar region 110, and The surface region 112 refracts another portion of the illumination ray 118b and exits the surface region 112 such that the illumination ray 106 is uniformly illuminated perpendicular to the planar region 110. In one embodiment, the material of the transparent substrate 104 is selected from the group consisting of polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), and polystyrene (PS). ), a group consisting of methyl methacrylate-styrene (MS) and glass.

In an embodiment, the surface region 112 of the transparent substrate 104 is distributed with a plurality of microstructures 120, and the microstructures 120 reflect the portion of the illumination light 118a to the outside of the planar region 110 to form a light distribution curve. For example, a batwing type light distribution curve (in cd/klm) or a concentrated light distribution curve (in cd/klm). In one embodiment, the microstructures 120 are a plurality of concave regions or a plurality of convex regions. As shown in FIG. 1, the plurality of microstructures 120 are complex convex regions.

Specifically, the transparent substrate 104 is curved along a planar area (ie, an X-Y plane), and the illumination light of the light source 102 is introduced into the transparent substrate 104 along the curved transparent substrate 104. The light is transmitted through the microstructure 120 of the transparent substrate 104, and the microstructure 120 affects the total reflection of the transparent substrate 104, so that the light is refracted from the transparent substrate 104 and reflected to the outside of the transparent substrate 104. In other words, the transparent substrate 104 is curved in a planar region (i.e., the X-Y plane). The curved luminaire 100 of the present invention extends the arrangement of the light source 102 along the planar area 110 by the transparent substrate 104 to produce curved lamps 100 of various curved shapes, and makes the illumination light of the curved luminaire 100 more uniform.

In addition, in the curved luminaire 100 of the present invention, the length of the at least one first side surface 114 (for example, the length of the inner half circumference) is greater than the length of the at least one second side surface 116 (for example, the radial length of the inner side and the outer circumference). ). Further, the length of the side surface of the light source 102 is set to be smaller than the length of the side surface of the light source, that is, the light source 102 is disposed on only a part of the side of the light source 102, so that the cost of the light source is effectively saved, but the light source 102 is not affected by the transparent substrate 104. Evenness.

Referring to FIG. 1B, a perspective view of a curved luminaire 100a having a reflective sheet 122, a gusset 124, and a diffuser 126 in the present embodiment is illustrated.

Specifically, the reflective sheet 122 is adjacent to the surface region 112 of the transparent substrate 104 for reflecting another portion of the illumination light 118b refracted from the surface region 112, such that another portion of the refracted illuminating light 118b re-enters the transparent substrate 104 and is worn. The outside of the planar area 110 is reached to generate illumination with the portion of the illumination ray 118a.

The cymbal piece 124 is disposed under the planar area 110 of the transparent substrate 104. The cymbal piece 20 is distributed with a plurality of geometric structures, for example, a structural component having a triangular cross section, so as to guide the light emitted from the transparent substrate 104 to be emitted outward. In order to form a light distribution curve, the light can be evenly scattered and not excessively concentrated toward the center of the lamp.

The diffusion sheet 126 is disposed below the cymbal piece 124, and the diffusion piece 126 is located below the cymbal piece 124 such that the diffusion piece 126 directly faces the cymbal piece 124 to adjust the angle of the light emitted through the cymbal piece 124. The above-mentioned illuminating light 118b scattered on both sides is concentrated toward the center of the lamp to form a more uniform surface light source.
