A decorative lamp capable of providing escape direction guidance comprises a matrix module and a matrix composed of a plurality of light emitting bodies. The matrix module comprises a communication circuit, a central chip and a driving circuit. The communication circuit receives the control signal from an alarm module. The central chip receives the control signal transmitted by the communication circuit, and outputs the switching signal to the driving circuit after processing the data. The driving circuit drives each light emitting body of the matrix to be on/off depending on the switching signal. The lamp may be usually used as a decorativelamp, and when hazard occurs, it may be used as an emergency lamp displaying the escape direction pattern. |
