ABSTRACT:
In an LED (Light Emitting Diode) including a cover covering an LED element, the cover is formed using glass having a composition RnSiO2-n/2. The glass according to the present invention is low melting point glass with a softening temperature of −40° C. to 300° C., melts at lower temperatures compared to conventional glass, and can safely form the cover without damaging the LED element. Since glass has better moisture shield performance and resistance to light compared to epoxy resins, the cover is formed using glass, and consequently deterioration of the LED element and a phosphor caused by moisture is reduced, deterioration of the cover caused by light is reduced, and changes in color and luminous intensity are restrained.
