Current LED heat abstractor many employings fin pattern, heat transference efficiency is low, and fin machining cost is high, adopts monoblock type more, can not dismantle.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of device effectively can accelerating LED light source heat radiation, improves heat transference efficiency, thus ensure the functional reliability of LED light source, and in addition, it also has easy processing, is easy to the advantage of dismounting.
The utility model is achieved through the following technical solutions:
A kind of LED light source heat abstractor, comprise the main component for support circuit plate, circuit board is provided with LED light source, also comprise some heat-radiating rod, described main component is distributed with screwed hole, one end of heat-radiating rod is provided with the threaded post of mating with screwed hole, and heat-radiating rod is bolted on described screwed hole by threaded post.
As preferred embodiment, described heat-radiating rod is strip helical structure.
As preferred embodiment, the other end that described heat-radiating rod is not provided with threaded post is provided with yi word pattern spiral shell head.
As preferred embodiment, described main component is tabular, and the upper surface of main component is located at by circuit board, and screwed hole is distributed in the lower surface of main component.Further, described screwed hole is triangular arranged.The upper surface of described main component is provided with one deck heat conduction mud, and described circuit board is fixed on described heat conduction mud.
The beneficial effects of the utility model are: the utility model adopts heat-radiating rod as heat sink body, its volume is little, compact conformation, efficiently radiates heat area is large, better with the thermal convection current effect of cold air, the heat transference efficiency of heat abstractor is higher, effectively improves radiating efficiency and the service life of LED light source, ensure that the functional reliability of LED light source; Heat-radiating rod adopts the mode be spirally connected to be fixed, and possesses detachability, easy to assembly, is easy to safeguard.
