Abstract
An LED automobile lamp includes a lens, a heat dissipation shell, a light source pillar, and a rear cover. The heat dissipation shell is mounted with a light-reflecting surface, the light source pillar is mounted at the bottom of the heat dissipation shell, the lens is arranged at the top of the heat dissipation shell, and the rear cover is arranged at the bottom of the light source pillar. A first light source plate and a second light source plate are symmetrically arranged on two sides of the light source pillar. Both the first light source plate and the second light source plate extend into a light-reflecting region surrounded by the light-reflecting surface and the lens. The top of the light source pillar is provided with a light-shielding sheet, and a bottom of the light source pillar is provided with a stepped plane coupling with the heat dissipation shell.
