Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to description word to make those skilled in the art.
A heat abstractor for LED plane light source, refers to accompanying drawing 1, comprising:
LED plane light source 1,
Interior substrate 2, the back of its lower surface and described LED plane light source is adjacent to;
Outer substrate 3, it is symmetrically set in described interior substrate both sides;
Radiating fin 4, it lays respectively at outside described outer substrate;
