Puzzle building block capable of changing light-emitting areas

Abstract

A puzzle building block capable of changing light-emitting areas includes a building block board, a circuit board, light-emitting elements and building bricks. The building block board includes a plate body and connection portions. The connection portions are disposed on the top surface of the plate body. The circuit board is adjacent to the bottom surface of the building block board. The light emitting elements are disposed on the circuit board, and the light emitted from the light emitting elements passes through the building block board via the connection portions. The building bricks are fitted with the connection portions and shield the corresponding connection portions, thereby forming letters or patterns. Therefore, the light emitted from the light-emitting elements can form various letters or patterns on the top surface of the building block board. The present invention also provides a puzzle building block assembly including the above-mentioned puzzle building blocks.
