Description
Technical field
The utility model relates to a kind of LED lamp field of radiating, more particularly, and it relates to a kind of ventilation effect is good, radiating efficiency is high LED heat abstractor.
Background technology
The features such as profile is flexible owing to having for LED lamp, brightness is large, save electric energy, environmentally friendly and applied range, the market share that it is occupied in illumination market is increasing.But along with in the use procedure of LED, the heat dissipation problem of LED lamp, and LED light declines, becomes the key factor that a restriction LED service life and LED apply.Especially in high-powered LED lamp, input power only has the electric energy conversion of 15% ~ 20% to be that luminous energy exports, and all the other then convert heat energy to, if these heats fail to discharge the external world in good time, the luminous efficiency of light fixture not only can be made to reduce, and LED chip Yin Wendu may be caused too high and lost efficacy rapidly.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide the LED heat abstractor that a kind of ventilation effect is good, radiating efficiency is high.
For achieving the above object, the utility model provides following technical scheme:
A kind of LED heat abstractor, comprise the shell that pedestal is connected with pedestal, described outer side face is circumferentially evenly provided with some square grooves, described square groove is provided with the first through hole near shell aperture end, described outer side face is provided with the second through hole, described second through hole is positioned at above square groove, described shell medial surface all be provided with arc groove, described arc groove and square groove interval are arranged.
Preferably, in described shell, be also provided with fin, described fin and arc groove sidewall inconsistent.
Preferably, described fin is also provided with passage.
Preferably, in described shell, be also provided with insert-connecting plate, described insert-connecting plate and arc groove inconsistent.
Preferably, be provided with mount pad in described arc groove, described mount pad matches with installation through hole.
Preferably, described mount pad is two, and described insert-connecting plate is embedded between arc groove sidewall and mount pad sidewall.
Compared with prior art, the beneficial effects of the utility model are: described outer side face is circumferentially evenly provided with some square grooves, square groove adds the area of dissipation of shell, described square groove is provided with the first through hole near shell aperture end, described outer side face is provided with the second through hole, described second through hole is positioned at above square groove, first through hole and the second through hole match, air in shell is circulated with extraneous, form upper and lower convection current, strengthen ventilation effect, and square groove is positioned at the first through hole, second through hole centre position, cross-ventilation fully contacts with square groove, strengthen radiating effect, described shell medial surface is provided with arc groove, described arc groove and square groove interval are arranged, substantially increase area of dissipation, and be arranged on outer side face due to square groove, arc groove is arranged on shell medial surface, both make full use of shell inside and outside space heat elimination, greatly strengthen radiating effect.
