As preferably, the same position of every fin is provided with at least one or a circle air-vent, thereby forms a convection channel that makes progress, and produces stack effect, increases new air convection channel, further enhance heat effect.
As preferably, be provided with the combination that a circle and supporter closely contact at the upper surface of every fin and the binding site of supporter and/or lower surface position, described combination and fin integrative-structure, thus can strengthen the heat conductivility of fin and supporter.
As preferably, as preferably, both are integrative-structures at least among described fin, supporter, the substrate three, thereby reduce thermal resistance, improve radiating effect.
As preferably, described supporter is formed with top-down cavity, and the cavity inwall can be used as cooling surface area, further the enhance heat effect.
As preferably, the hypomere of described supporter is provided with horizontal cross-ventilation hole, thereby can strengthen cross-ventilation, and the draining blowdown improves radiating effect.
As preferably, described substrate is the plate-type heat-pipe that inside is provided with cavity, and cavity is filled with the easily liquid medium of gasification of capillary structure, support member and chance heat, and substrate top is the heat pipe condensation end, and the substrate bottom is the heat pipe evaporation ends.Liquid medium absorbs in the substrate bottom and gasifies after the LED lamp conducts the heat of coming, thereby reduce the temperature of substrate bottom, rise and condensation gradually in liquid medium gasification back, distribute for fin via fin the supporter and the further conduction on heat transferred substrate top, condensed liquid medium is through getting back to the body lower end under capillary structure effect and the gravity effect, thereby said process constantly circulation is realized the good heat radiating of LED light fixture to the substrate cooling.Wherein, plate-type heat-pipe can be strengthened the heat radiation cooling effect of radiator to the LED light fixture as substrate, thereby prolong the service life of LED light fixture.
As preferably, described radiator is made of the array radiating subassembly, and described array radiating subassembly is dot matrix and arranges.Radiating subassembly adopts dot matrix to arrange, no matter is arranged on upper surface of base plate or substrate side surfaces, and the passage that forms between radiating subassembly all plays the forced convertion radiating effect that strengthens wind.
Therefore, it is big that the present invention has an area of dissipation, and good heat dissipation effect can prolong characteristics such as LED light fixture service life.
