An LED light metal frame comprising multiple substrate strips in a parallel arrangement. Each substrate strip comprises a first lead (1), a second lead (2), and a thermal lead (3). Light-emitting areas (4) and heat dissipation areas (5) are alternately provided on the substrate strips. The first leads (1) within the light-emitting areas (4) are inverted "L" shapes in symmetrical arrangements. The thermal leads (3) of the heat dissipation areas (5) protrude downwards. The LED light metal frame has the multiple substrate strips formed at once and the substrate strips directly connected. With the addition of the thermal leads, heat dissipation performance is improved. |
