[0038] Please refer to Figure 1A and Figure 1B The light emitting structure 100 includes a circuit layer 110, at least one light emitting element 114 (four are shown in the figure), a light guide plate 120 and a housing 130. The circuit layer 110 has a first surface 111 and a second surface 112. The first surface 111 is coated with a reflective material or has a first reflective sheet 133 on the first surface 111. The reflective material is, for example, white paint or other high reflectivity paint. The first reflective sheet 133 is, for example, a reflective metal layer or a reflective layer with a high reflectivity material, which is independently disposed between the circuit layer 110 and the light guide plate 120. In addition, the connection port 108 is disposed on the second surface 112 of the circuit layer 110 and exposed at a port 130a of the housing 130. The connection port 108 can be electrically connected to the circuit layer 110. The connection port 108 is, for example, a type-C or other type of interface. The connection port 108 is used to receive a power signal to supply power to the light emitting element 114.

[0039] The circuit layer 110 is, for example, a printed circuit board or a flexible circuit board, and the light emitting element 114 is disposed on the circuit layer 110 and electrically connected to the circuit layer 110. The light emitting element 114 can receive a power signal from the connection port 108 to emit light. The light emitting element 114 is, for example, a light emitting diode or other types of solid-state light sources, and the light emitting surface 115 of the light emitting element 114 is disposed downward to emit light toward the light guide plate 120.

[0040] The circuit layer 110 has a central circular hole 113, and the light emitting elements 114 are disposed around the central circular hole 113 and dispersed in different directions, so that light can be evenly emitted from the center of the light guide plate 120 to the surroundings. In addition, the first reflective sheet 133 has at least one hole 135 (four holes are shown in the figure) corresponding to the light emitting element 114.

[0041] The light guide plate 120 is located below the circuit layer 110, and the light guide plate 120 is disposed between the first reflector 133 and the second reflector 134. The first reflector 133 and the second reflector 134 can also be called reflective layers, and the portion of the light guide plate 120 exposed by the reflective layer corresponds to a light-transmitting area (e.g., the opening 132 or the transparent material area 128) of the housing 130. The light guide plate 120 has a central opening 123 and a fixing seat 124 disposed in the central opening 123. The central opening 123 is aligned with the central circular hole 113 of the circuit layer 110, and a locking member 125 can pass through the fixing seat 124, the first reflector 133 and the circuit layer 110. In addition, the housing 130 is provided with a hollow cylinder 131 relative to the locking member 125. The hollow cylinder 131 has an internal thread.

[0042] In another embodiment (not shown), the light guide plate 120 may be located above the circuit layer 110, and the light guide plate 120 is disposed between the first reflector 133 and the second reflector 134. In this case, the light emitting element 114 is disposed on the upper surface of the circuit layer 110, and the light emitting surface 115 of the light emitting element 114 is disposed upward to emit light toward the light guide plate 120.

[0043] Please refer to Figure 3 In one embodiment, the locking member 125 can be a stud. One end of the locking member 125 passes through the fixing seat 124 of the light guide plate 120 and the central circular hole 113 of the circuit layer 110 from the bottom surface 122 of the light guide plate 120 and is fixed in the hollow cylinder 131 of the housing 130, so that the light guide plate 120 and the circuit layer 110 are fixed below the housing 130.

[0044] Please refer to Figure 3In one embodiment, the first reflective sheet 133 is, for example, a top reflective sheet, and the second reflective sheet 134 is, for example, a bottom reflective sheet. The second reflective sheet 134 is, for example, a reflective metal layer or a reflective layer having a high reflectivity coating. In addition, the housing 130 covers the circuit layer 110 and the light guide plate 120, and only the peripheral surface of the light guide plate 120 is exposed in an opening 132 of the housing 130.

[0045] Please refer to Figure 3 In one embodiment, the light guide plate 120 may be a disk, and the light guide plate 120 has at least one light entrance portion 126 and a light exit portion 127. The light entrance portion 126 may have a notch (or opening, see Figure 3 ), the recess is sunken into the interior of the light guide plate 120. The light emitting element 114 is arranged opposite to the recess or in the opening, that is, the light emitting surface 115 of the light emitting element 114 faces the recess, so that the light of the light emitting element 114 can enter the light guide plate 120 through the light entrance portion 126. In one embodiment, the width of the light guide plate 120 along a direction (for example, a horizontal direction) is greater than the width of the circuit layer 110 along the direction. The maximum width of the light guide plate 120 is, for example, greater than the maximum width of the circuit layer 110, and a part of the light guide plate 120 is not covered and is exposed, and the light emitted by the light emitting element 114 can emit light through the exposed part of the light guide plate 120.

[0046] Please refer to Figure 3 In one embodiment, the light incident portion 126 has a conical notch (or opening), the opening size of which gradually decreases from top to bottom to form a V-shaped groove, and the opening angle of the V-shaped groove is greater than 90 degrees, for example, about 100 degrees to 160 degrees. The light of the light emitting element 114 can be diverged outward from the light emitting surface 115 and incident on the V-shaped groove.

[0047] Please refer to Figure 3 In one embodiment, the light exit portion 127 is located on the side of the light guide plate 120, that is, on the peripheral surface of the light guide plate 120. The light exit portion 127 of the light guide plate 120 may be an inclined surface, and the inclined surface forms an acute angle θ with respect to the upper surface of the light guide plate 120. The acute angle θ is, for example, about 45 degrees to 60 degrees. When the light L diffuses outward through the light guide plate 120, the light L may leave the light guide plate 120 through the light exit portion 127 of the light guide plate 120 and exit toward the bottom of the housing 130.

[0048] Please refer to Figure 3 In one embodiment, the housing 130 can be a housing of any shape, such as a semi-spherical shape or other geometric shapes (such as a square shape, a cone shape, etc.). The bottom of the housing 130 has an opening 132 (see Figure 1B), the opening 132 exposes the light exit portion 127. That is, the housing 130 covers the upper portion of the light guide plate 120, and only the light exit portion 127 of the light guide plate 120 is exposed at the bottom of the housing 130, so that the light L can be emitted toward the bottom of the housing 130.

[0049] Please refer to Figure 3 , the second reflective sheet 134 is disposed on the bottom surface 122 of the light guide plate 120 to reflect the light L. In addition, a light shielding layer (such as a bottom pad 136) is disposed below the second reflective sheet 134, that is, the second reflective sheet 134 (reflective layer) is disposed between the light guide plate 120 and the light shielding layer. In the case where the second reflective sheet 134 is not disposed, the light shielding layer (such as the bottom pad 136) can be directly disposed on the bottom surface 122 of the light guide plate 120, or a reflective material is coated on the bottom pad 136. The reflective material is, for example, white paint or other high reflectivity paint to reflect the light L. Since the bottom pad 136 and the second reflective sheet 134 are both opaque materials, the light L is only diffused outward from the light guide plate 120 and emitted from the opening at the bottom of the housing 130 to form a ring-shaped lighting around the housing 130.

[0050] Please refer to Figure 2A In another embodiment, the housing 130 is, for example, plastic, and has a light-transmitting material area 128 (or light-transmitting area, indicated by dotted lines) around the housing 130. That is, the housing 130 can be made of different light-transmitting materials, the material of the light-transmitting material area 128 is light-transmitting, and the materials of the remaining areas are not light-transmitting. The light-transmitting material area 128 is connected to the light-emitting portion 127. After the light leaves the light guide plate 120 through the light-emitting portion 127, the light L is emitted from the light-transmitting material area 128 to form a ring-shaped illumination around the housing 130.
