LED LIGHTING DEVICE AND MANUFACTURING METHOD FOR LAMP BRACKET FOR LED LIGHTING DEVICE

摘要

An LED lighting device. A lamp bracket (100) or lampshade (304) made of an aluminum plate with excellent heat dissipation directly performs the work of heat dissipation for the whole lamp. One side of a PCB (200) is provided with LED beads and the opposing side thereof is attached to the bottom face of a lamp bracket accommodation groove (101), there being no heat sink between said two sides; the lamp bracket (100) or lampshade (304) is made of an aluminum plate that conducts heat very well, and said LED lighting device dissipates heat by means of the lamp bracket (100) or the lampshade (304). The LED lighting device does not require the addition of a heat sink, and the stretched aluminum lamp bracket only requires one-fifth to one-third of the material required for a die-cast aluminum lamp bracket, but can achieve heat dissipation performance that is the same as or better than die-cast aluminum.
