Abstract
The invention discloses a double-sided LED lamp bead, which comprises a first electrode, a second electrode and an insulated body. The upper part of the body is provided with a first notch, and the lower part of the body is provided with a second notch. The first notch and the second notch communicate with each other; the first electrode is located at the bottom of the first notch; the upper surface of the first electrode is separated from a first LED chip, and the second electrode is located at the top of the second notch; A second LED chip is provided on the lower surface of the electrode; the first LED chip is respectively connected to the first electrode and the second electrode through gold wires, and the second LED chip is respectively connected to the first electrode and the second electrode through gold wires; the first LED chip is respectively connected to the first electrode and the second electrode through gold wires; Fluorescent glue is filled in the notch and the second notch. The double-sided LED lamp bead provided by the present invention not only realizes double-sided light emission, but also improves the luminous efficiency of the upper and lower sides of the lamp bead.
Description
technical field [0001] The invention relates to the technical field of LED production, in particular to a double-sided LED lamp bead. Background technique [0002] Some LED lamps or light strips need to be able to emit light on both sides, so some LED packaging technologies that can emit light on both sides have appeared accordingly. For example, the patent with the authorized announcement number CN 103187514A proposes an LED packaging structure, although it can realize both sides of the upper and lower sides to emit light, but there are still the following deficiencies: (1) A transparent packaging substrate is provided, and when the light passes through the substrate, there will be a small amount of light. The light is absorbed, affecting the luminous efficiency of the lamp bead. (2) The substrate is directly encapsulated with transparent silica gel, and no cup is provided, which causes some light to be emitted from the side, and the luminous efficiency of the upper and lo...
