Abstract: A combined type single stud illuminating building block includes a circuit board, an illuminating member and an outer housing. The circuit board includes a top side and a bottom side opposite to each other. The circuit board is extended to form at least one first connection portion. The bottom side includes an electrode circuit. The illuminating member is mounted on the top side and electrically connected with the electrode circuit. The outer housing includes a connection hole to receive the circuit board and the illuminating member. The outer housing is hollow and light transmittable. The outer housing includes at least one second connection portion connected with the at least one first connection portion, respectively. Thus, the combined type single stud illuminating building block can be connected with the building block having various numbers of engaging studs to enhance degrees of freedom and variability of connection.

Abstract: A semiconductor light emitting diode chip relates to the field of production technologies of a light emitting diode. In the present invention, corresponding graphical current extension layers are respectively disposed below an N pad and a P pad, and in all light emitting compound areas, there is electronic compound light emitting. Compared with the prior art, an area of a light emitting compound area is increased, which can effectively improve current distribution and light emitting brightness of a chip. In addition, graphical current extension can effectively increase an adhesion of a pad on a surface and improve the reliability of a chip.

Abstract: An illuminating building block with high light transmission having a positioning structure for an electric connection member and a method of manufacturing the same provide projection strips disposed on an interior surface of a top cover and arranged at intervals, and slots disposed between the projection strips. The electric connection members are inserted into the slots to preliminarily position the electric connection members and align elastic pieces of the electric connection members with hollow studs of the top cover. The elastic pieces would not be constricted in the top cover due to the misalignment between the elastic pieces and the hollow studs. Therefore, the elastic pieces can accurately pass through the hollow studs and be projected out of the top cover. When the illuminating building blocks are connected together, the connected building blocks can have a stable power transmission and illuminate together.

Abstract: An illuminating building block with high light transmission includes a base, a top cover, a circuit board and at least one illuminating member. The illuminating building block uses electric connection members connected with the circuit board to electrically connect with the adjacent illuminating building block. Because the electric connection members are disposed by the top cover and a side wall, the electric connection members do not block the light emitted from the illuminating member. Thus, the illuminating building block is provided with the characteristic of high light transmission. Moreover, due to elasticity of the electric connection members, the electric connection members are pressed against the circuit board of the adjacent illuminating building block. Therefore, the electric connection between connected illuminating building blocks is more secure.
