Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

Referring to fig. 2-3 and 5, the utility model discloses a five-color patch lamp bead, which comprises a base 10, a small lamp bead 20 and an electrode pin 30. Wherein the base 10 serves to support and provide a mounting position for the small lamp beads 20 and the electrode pins 30, and the base 10 is an insulating member. Five small lamp beads 20 are fixedly arranged on the top surface of the base 10, the five small lamp beads 20 are respectively used for emitting light rays with five different colors, each small lamp bead 20 is respectively connected with a pair of electrode pins 30, specifically, the anode of each small lamp bead 20 is connected with one anode pin, and the cathode of each small lamp bead 20 is connected with one cathode pin, so that the total number of the electrode pins 30 is five pairs and ten.
