Abstract
The utility model discloses an LED (Light-emitting Diode) aluminum substrate with a micro heat dissipation structure. The LED aluminum substrate has an upper side face and a lower side face which are relative, and a plurality of LED anodes and cathodes are respectively welded on the upper side face of the aluminum substrate. A plurality of bumps or grooves are formed on the lower side face of the aluminum substrate. The bonded area of the LED (Light-emitting Diode) aluminum substrate with the micro heat dissipation structure and heat-conducting glue can be increased, the bonding power is increased, the heat dissipation area ratio is larger, and the heat dissipation effect is increased.
Description
Technical field
The utility model relates to a kind of LED aluminium base, relates in particular to a kind of LED aluminium base with little radiator structure.
Background technology
Heat radiation is the large problem that the LED lighting engineering exists always, and is bringing into play very important effect as the aluminium base of main radiator structure, and it generally is selected from the material with better heat conductivity and makes.But present aluminium base surface is without little radiator structure, namely is generally the plane, and this just makes aluminium base radiating surface when heat radiation less, radiating effect is general, because aluminium base is planar structure, less in adhesion when heat-conducting glue is combined simultaneously, break-off appears easily.
Summary of the invention
In order to overcome defects, the utility model provides a kind of LED aluminium base with little radiator structure, and it not only can increase and the heat-conducting glue bonded area, increases cohesive force, and has larger area of dissipation ratio, improves radiating effect.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of LED aluminium base with little radiator structure, have relative upper side and downside, the anode of several LED and negative electrode are welded on respectively on the upper side of described aluminium base, are formed with several projections on the downside of described aluminium base.
As further improvement of the utility model, the some projections on the downside of described aluminium base are rule and distribute.
As further improvement of the utility model, several projections on the downside of described aluminium base are the formation that stretches out respectively of several zones at interval on the downside of described aluminium base.
As further improvement of the utility model, one of several projections on the downside of described aluminium base are triangular in shape, square and circular.
The utility model also provides a kind of LED aluminium base with little radiator structure, have relative upper side and downside, the anode of several LED and negative electrode are welded on respectively on the upper side of described aluminium base, are formed with several grooves on the downside of described aluminium base.
As further improvement of the utility model, the some grooves on the downside of described aluminium base are rule and distribute.
As further improvement of the utility model, the some grooves on the downside of described aluminium base are several zones at interval formation that caves inward respectively on the downside of described aluminium base.
As further improvement of the utility model, one of the some grooves on the downside of described aluminium base are triangular in shape, square and circular.
The beneficial effects of the utility model are: several small projections are set or groove forms little radiator structure by the lower surface at aluminium base, increase the specific area of aluminium base, not only make aluminium base and heat-conducting glue that larger contact area is arranged, increase its cohesive force, and effective increasing heat radiation area, improve the radiating effect of aluminium base, thereby improve the LED radiating effect.
