Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.

With reference to fig. 1-5, the present application provides a modular light source for a stage light, the modular light source comprising: the circuit 300 and the first power line 100 and the plurality of

second power lines

201 and 206 etched on the circuit board 300 are respectively soldered with a pad 40 on each of the second power lines 201/202/…/206.

One or more LED chips 30(LED diodes) are arranged on each bonding pad 40, the LED chips 30 are respectively electrically connected with the first power line 100 and the second power line 201/202/…/206, dam adhesive 10 surrounds the outer side of each bonding pad 40, the dam adhesive 10 surrounds the electrical connection points of the bonding pads 40 and the LED chips 30, light diffusion adhesive 50 covers the upper portion of the dam adhesive 10, and a pattern sheet 60 is arranged on the upper portion of the light diffusion adhesive 50.
