PURPOSE:To sealing a light emitting diode with high reliability by employing specific ultraviolet curable low viscosity resin composition. CONSTITUTION:Triallyl isocyanurate, polychiol series are selected as ultraviolet curable resin, an LED is sealed by method, e.g., potting, casting, dipping dropping and the like with resin composition to which a light strating agent, a heat discoloration preventive agent, coloring agent are added to the composition, and is then ultraviolet rays are emitted to cure the resin. Since the triallyl isocyanurate, polychoil series as ultraviolet ray curable resins are very low viscosity liquid, the workability in the potting, casting and the like is preferable, and defoaming operation can be further facilitated. |
