An LED light plate structure (100) comprising: a mount plate strip (102) and a substrate strip (104). The lower surface of the substrate strip (104) is joined with the upper surface of the mount plate strip (102). The mount plate strip (102) is provided with a substrate strip groove (106), a substrate strip engaging groove (108), and a wire engaging groove (110). The substrate strip (104) comprises a first electrical lead (112), a second electrical lead (114), and a thermal lead (116). The substrate strip (104) is provided with a light-emitting area and a heat dissipation area. In the light-emitting area, the first electrical lead (112) is provided with a connector and the thermal lead (116) is provided with a trapezoidal protrusion. In the heat dissipation area, the thermal lead (116) is provided with a recessed slope and cooling fins. Application of the LED light plate structure (100) provides a simple and compact structure, great electrical conductivity, high heat dissipation efficiency, extended LED light bulb service life, and great luminous effects. |
