Patent ID: 8441022

Claim:
A semiconductor light-emitting device, for emitting light to an outside, the semiconductor light-emitting device being mountable on a substrate, the semiconductor light-emitting device comprising: at least one semiconductor light-emitting element; a semiconductor element; a first lead frame including a first inner lead and a first outer lead connected to each other, the first inner lead having a surface on which the at least one semiconductor light-emitting element is provided, the first outer lead being connectable to a corresponding electrode of the substrate; a second lead frame including a second inner lead and a second outer lead connected to each other, the second inner lead having a surface on which the semiconductor element is provided, the second outer lead being connectable to a corresponding electrode of the substrate; and a fixing member for fixing the first lead frame and the second lead frame thereto, both the first outer lead connected to the first inner lead penetrating the fixing member and the second outer lead connected to the second inner lead penetrating the fixing member being provided on an outer wall surface of the fixing member, the first outer lead having a surface area greater than that of the second outer lead, the device further comprising an insulating layer formed between the first inner lead and the second inner lead so as to be oblique to one side of the semiconductor light-emitting device, the insulating layer being made of a material identical to that for the fixing member.
