[0002] Mixed light lamps are generally lamps made by mixing light between multiple LEDs of different colors, and mixed light lamp beads are LED lamp beads that can normally emit light. During installation of LED mixed light lamp beads, corresponding LED supports are usually used.

[0003] An invention patent with the authorization announcement number CN208422951U discloses a multi-chip LED mixed light support structure. It comprises a support, PIN pins, light-emitting chips mounted in the support, heat-conducting blocks mounted on the bottom surface of the support, and encapsulating glue for encapsulating the light-emitting chips in the support. The encapsulating glue is preferably epoxy resin. There are preferably four to six heat-conducting blocks. The light-emitting chips are arranged on the fourth heat-conducting block on the bottom surface of the support and are connected in parallel, in series, or in a mixed connection. The light-emitting chips are electrically connected to other heat-conducting blocks and their respective PIN pins. The encapsulating glue encapsulates the light-emitting chips in the support.
