PURPOSE:To provide a method for the formation of a lens wherein resin will not flow even if slightly too much of it is potted. CONSTITUTION:The end 3 of the resin filling section 2 of a case 1 with a LED luminous element formed is coated with a substance of low surface free energy to form a coating film 5. Resin is injected into the resin filling section 2, and heated and hardened. Thus resin is repelled by the coating film 5 on the end 3 of the case 1, and its flow is thereby prevented. |
