PURPOSE:To improve thermal shock resistance by making a sealing resin gel through the primary exposure of energy rays at a predetermined level and curing the resin through the secondary exposure of energy rays at a higher level. CONSTITUTION:The basic section of a LED is constituted in such a manner that a light-emitting element 1 is joined with a cathode lead 4 by a conductive material 2 such as solder, one of a connector wire 3 in Au, etc. is welded to the light-emitting element 1 through a thermocompression bonding method, etc., and the other is welded to an anode lead 5. The light-emitting element 1 is sealed with the resin in order to protect it from external environment, such as moisture, heat, vibration, a shock, etc. In this case, the sealing resin 6 is made gel through the primary exposure of energy rays of 30mW/cm<2> or less, and cured through the secondary exposure of energy rays of 70mW/cm<2> or more. |
