Structure of fin type LED light/write cup die lamp

摘要

Topic The heat dissipation area is increased, simultaneously heat is discharged effectively with the internal air hole and structure of the fin type LED light/write cup die lamp which achieves the satisfactory heat dissipation effect is offered.SolutionsStructure of the fin type LED light/write cup die lamp light/write cup includes the LED illuminant 2 which is installed inside 1 and the light/write cup. Inside the light/write cup with air, it has the hollow chamber 10. Furthermore the multiple heat dissipation fins which extend outside ring facilities are done around outside the light/write cup, install the LED illuminant in the hollow interior, circuit board include the light-emitting diode 21 which is installed on 20, and the circuit board. Among those, each heat dissipation fin dividing from all roots, and root end includes the multiple fork sections which extend, at the same time, outside rising and falling penetrating completely forms the air hole 12 between the fork sections of each heat dissipation fin, covers each heat dissipation fin which in addition is adjacent with the mutually close fork section and root, inside penetrating completely up and down, the air hole 13 forms.
