Abstract: A conductive building block having multi-sided conductivity includes a first stud disposed on a top side surface of an outer housing; a second stud disposed on a lateral side surface of the outer housing; and an engaging recess disposed on a bottom side surface of the outer housing. A circuit board, first positive-and-negative electrode connection pieces and second positive-and-negative electrode connection pieces are received in the outer housing. An illuminating member is mounted on the circuit board. The first positive-and-negative electrode connection piece is electrically connected with the circuit board and passes through the first stud. The second positive-and-negative electrode connection piece is electrically connected with the first positive-and-negative electrode connection piece and passes through the second stud.

Abstract: A method of manufacturing an embedded LED circuit board, including the step of: forming a through hole in a circuit substrate, the through hole communicating a first surface and a second surface of the circuit substrate; embedding a LED in the through hole of the circuit substrate; and electrically connecting two pins of the LED with a circuit disposed on the second surface of the circuit substrate. Because the LED is disposed in the through hole of the circuit substrate, not disposed on the surface on the circuit substrate, the LED is embedded in the circuit substrate. Therefore, the thickness of the embedded LED circuit board is reduced and it is advantageous to assembling the embedded LED circuit board in the electronic devices having limited volume.

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 conductive base for illuminating building blocks has a base plate, an anode conductive component, and a cathode conductive component. The base plate further has a plurality of hollow studs. The anode conductive component and the cathode conductive component electrically connect to an external power supply. The anode conductive component and the cathode conductive component are projected out of recesses of the hollow studs to contact circuit boards of illuminating building blocks stacked on the base plate and then build electric connections. The neighboring illuminating building blocks stacked on the base plate can emit light together by the above base plate without intricate circuits.

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.
