Abstract
A light source module includes a circuit board, a plurality of point light sources fixed on both sides or one side of the circuit board, and a control circuit module configured for controlling ignition and extinction of the plurality of point light sources. The point light sources on each side of the circuit board are arranged in N parallel branches arranged from top to bottom. The point light sources on each parallel branch are arranged in an inverted V-shape, where N is a natural number less than or equal to 10. In the present disclosure, several parallel branches are configured to simulate different levels of a candle flame, and despite of a small number of point light sources required, a simple control circuit and a low cost, rich levels and changes in the flame are presented, and good simulation effect is achieved.
