Abstract

The invention relates to a watertightness packaging method of an LED illumination module, comprising an LED illumination module (1) and a glass lamp shade (2), wherein the LED illumination module (1) comprises a sealing connector lug (4) and a metal heat sink (5). The watertightness packaging method is characterized by comprising the following step of: carrying out watertightness sealing on an interface positioned between the metal heat sink (5) and the glass lamp shade (2) by utilizing a glass-metal sizing mixture (9) melting and adhering principle. The invention can meet the outdoor illumination requirements of the LED illumination module, reduce the infiltration of moisture and water vapour, enhance the reliability and the durability of the LED illumination module, enable the LED illumination module to have longer service life and prevent the earlier failure of the LED illumination module.

Description

technical field [0001] The invention relates to a watertight packaging method for an LED lighting module. Background technique [0002] Light-emitting diode (LED) is an electroluminescent device processed by semiconductor manufacturing technology. Its light-emitting mechanism is to use the recombination of electrons and holes to generate photons. This recombination effect can theoretically approach 100% quantum efficiency under continuous current and stable voltage drive. This method of electric injection can also avoid large Stokes shift, so LED has the advantages of high luminous efficiency, good color rendering, low power consumption, energy saving and environmental protection, high safety and reliability, and long service life. [0003] Since the first blue LED chip was successfully developed, there are currently two main technologies for obtaining white LEDs. One is to use high-brightness InGaN blue chips to excite yttrium aluminum garnet phosphors (YAG:Ce 3+ ) to obt...
