Abstract
An LED lead frame mounted on a platform of a lightbulb includes a metal polarity substrate, a metal retaining substrate and a casing for partially covering the metal polarity substrate and the metal retaining substrate. The metal retaining substrate is a sheet bent into a disposing portion and a carrying portion, and an included angle θis defined between the portions, and an abutting surface of the disposing portion abuts the platform, and a portion of the carrying portion not covered by the casing is provided for installing at least one LED chip. The metal polarity substrate is bent to form an included angle θ, and θ=θ, and 93°≦θ≦130°. The casing has a support member formed on the casing and protruded in a direction opposite to the direction of bending the metal retaining substrate. The LED lead frame enhances the illumination angle and light uniformity of the lightbulb.
