LIGHT SOURCE HAVING LIQUID ENCAPSULANT

摘要

In one embodiment, a light source comprising a substrate, a die, a liquid encapsulant, an attachment member and a resilient cover configured to hold the liquid encapsulant is disclosed. At least a portion of the resilient cover is easily stretchable so as to absorb size increment of the liquid encapsulant due to thermal expansion. One other embodiment discloses a light-emitting device comprising a die, a liquid encapsulant and the resilient cover. The resilient cover may comprise a dome shaped portion, a vertical portion and a thermal joint portion. In another embodiment, a lighting apparatus having similar resilient cover is disclosed. The resilient cover may further comprise a thermal joint portion having first and second indentations for absorbing thermal expansion.

1. A light source, comprising:
a substrate; a die disposed on the substrate; a liquid encapsulant surrounding the die; a resilient cover configured to hold the liquid encapsulant; and an attachment member to secure a portion of the resilient cover onto the substrate, wherein at least a portion of the resilient cover is stretchable so as to absorb size increment of the liquid encapsulant due to thermal expansion.
