Abstract

The invention relates to a method for encapsulating a water tightness of an LED lighting module by a foam material, which comprises an LED lighting module (1) and a glass lampshade (2), wherein the LED lighting module (1) comprises a metal heat sink structure (5) containing a sealing connector lug (4). The invention is characterized in that an interface between the metal heat sink structure (5) and the glass lampshade (2) is filled and sealed by utilizing the principle of thermal expansion of foam sealant. The invention has the advantage of meeting the outdoor lighting requirement of the LED lighting module, reducing the infiltration of moisture and water vapor, improving the reliability and durability of the lighting module, having longer service life, and avoiding early failure of the lighting module.

Description

technical field [0001] The invention relates to a method for watertightly encapsulating an LED lighting module with a foam material. 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 pho...
