Description

Technical Field

[0001] The utility model relates to the technical field of lamp beads, in particular to a patch lamp bead with a near-infrared spectrum. Background Art

[0002] SMD LED lamp beads are also called SMD LEDs, which are mainly used in lighting systems, decorations, electronic equipment indicators, backlights, displays and equipment. Common dual-color temperature lamp beads mainly fix multiple chips on a bracket, then connect the chips in series or in parallel through leads, and then apply different proportions of phosphors to multiple chips to adjust the color temperature, so that the lamp beads can achieve the effect of dual color temperature. After retrieval, the Chinese utility model patent with patent application number CN202120948852.9 discloses a single-lamp dual-color lamp bead packaging structure and a single-lamp dual-color lamp bead device. By achieving dual colors in the same bowl, two chips are fixed in the bowl, and the dual-color purpose is achieved in different current directions, which can reduce the opening of the bracket mold. It can be achieved by using the existing bracket, and glue is applied once, which improves the production efficiency while achieving dual colors. However, this single-lamp dual-color lamp bead packaging structure adopts a parallel connection method, and uses more circuits. If a large number of red light chips or blue light chips are welded, the wiring is more cumbersome, the scope of application is small, and it is not conducive to large-scale promotion.
