Abstract:
A multi-function signboard, comprising:a frame seat sinking downward to form a frame rib bounding a frame groove, and having two ends, each respectively connected to an end cap; an elongated light seat having connecting wires connected to a circuit board and a plurality of sets of light-emitting diodes (LEDs), each set having at least three LEDs of different colors to provide colored light of different colors, where the circuit board has a power source to cause at least one LED in each set of LEDs to flash alternately; a transparent and colorless light diffusion strip disposed on the light seat, the light diffusion strip and the light seat together disposed in the frame groove, the diffusion strip having holes therein accommodating the LEDs, the diffusion strip diffusing the colored light emitted by the LEDs; a transparent display board mounted in the frame groove in contact with the light diffusion strip, and having an ornamental marking to reflect the colored light emitted from the light seat and the light diffusion strip to achieve an ever-changing and multifarious lighting effect; and, a reflecting sheet adhered to the display board to reflect the colored light emitted by the LEDs to the display board.
