Abstract

The invention provides an LED lamp bead, an illuminating lamp and a manufacturing method of the LED lamp bead. The LED lamp bead comprises an LED support, a wafer and packaging glue, wherein the LED support is provided with a positive electrode and a negative electrode, and a polytetrafluoroethylene dispersion liquid coating is arranged at a preset position of the LED support; the wafer is fixed on the LED support, and the positive electrode and the negative electrode of the LED support are electrically connected with the wafer; and the wafer is packaged on the LED support through the packaging glue, the packaging glue is solidified to form a cambered surface, and the polytetrafluoroethylene dispersion liquid coating is connected with the packaging glue so as to prevent the packaging glue from flowing in the process from being injected into a support cup of the LED support to being solidified through the tension effect of the polytetrafluoroethylene dispersion liquid coating. The LED lamp bead has higher luminous flux extraction rate and brightness, the power consumption and the cost of a lamp can be reduced, and the LED lamp bead is simple in manufacturing process, high in production efficiency and high in yield.

Description

technical field [0001] The present application belongs to the technical field of lighting, and more specifically relates to an LED lamp bead, a lighting lamp and a method for manufacturing the LED lamp bead. Background technique [0002] At present, LED (Light-emitting Diode, light-emitting diode) lamp beads are more and more widely used in general lighting fields such as household lighting and commercial lighting, and plant lighting fields. However, with the development of society, people have higher and higher requirements on the light intensity and light quantum flux extraction rate of LED lights. The new LED lamp beads. The biggest difference between this new type of LED lamp bead and the conventional TOP patch lamp bead is that the conventional TOP patch LED lamp bead has a planar structure, while the new type of LED lamp bead has a spherical structure. Compared with the conventional TOP The light quantum flux extraction rate of SMD lamp beads has been greatly improve...
