Abstract
The invention discloses an LED lamp bulb with an active heat radiating function, comprising a lamp holder, wherein a fan is arranged below the lamp holder; an aluminum die-casting heat radiator is arranged under the fan; an LED aluminum substrate is arranged below the aluminum die-casting heat radiator; the LED aluminum substrate is provided with an LED light source; a diffusion cover is arranged below the LED aluminum substrate; a metal ring is arranged on the diffusion cover; the aluminum die-casting heat radiator comprises a base part, a plurality of first heat radiating fins and a plurality of second heat radiating fins; the center of the base part is provided with a through hole; an air inlet runner is formed between every two first heat radiating fins and an air outlet runner is formed between every two heat radiating fins; the inner side of the metal ring is provided with an inner thread; and each first heat radiating fin is provided with an outer thread matched with the inner thread of the metal ring. Air enters from the air inlet runners of the aluminum die-casting heat radiator, passes through the through hole in the center of the base part and is discharged along the air outlet runners, thereby bringing heat in the LED lamp bulb away, and therefore the life of the LED lamp bulb is prolonged.
Description
Technical field
The present invention relates to a kind of LED bulb with active heat radiating function.
Background technology
The led light source product saves money than incandescent lamp power saving 90% again because it is energy-conservation, life-span is 50 times of conventional bulb, price is 50% of highly sophisticated products of the same trade, LED is a photoelectric device, enjoy great popularity because it is energy-conservation, economical, utility time is long this year, only have the electric energy of 15%-25% to convert luminous energy in the course of work of LED, remaining electric energy is energy transform into heat energy nearly all, and the temperature of LED is raise.In great power LED, heat radiation is a large problem.For example: if 1 its photoelectric transformation efficiency of 10W white light LEDs is 20%, the electric energy energy transform into heat energy of 8W again then, if do not add cooling measure, then the device core temperature of LED can rise rapidly, when its junction temperature rises above maximum allowable temperature, LED can damage because of overheated, thereby has shortened the service life of LED lamp.
Therefore, be necessary to provide a kind of LED bulb with active heat radiating function.
Summary of the invention
Technical problem to be solved by this invention is: a kind of LED bulb with active heat radiating function that increases the service life is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of LED bulb with active heat radiating function, it comprises: lamp holder, the below of described lamp holder is equipped with fan, aluminium die casting radiator is installed below the described fan, the below of described aluminium die casting radiator is equipped with the LED aluminium base, described LED aluminium base is equipped with led light source, the below of described LED aluminium base is equipped with diffusion shell, on the described diffusion shell becket is installed, described aluminium die casting radiator comprises base portion, several first radiating fins that protrude out from base portion one side reach several second radiating fins that protrude out from the base portion opposite side, the central authorities of described base portion are provided with through hole, form the air intake runner between per two first radiating fins, form distinguished and admirable road between per two second radiating fins, the inboard of described becket is provided with internal thread, and described the first radiating fin is provided with the external screw thread that matches with the internal thread of becket.
The invention has the beneficial effects as follows: air enters from the air intake runner of aluminium die casting radiator, passes the through hole of base portion central authorities, and discharges along the air-out runner, and forms circulation, thereby takes away the heat in the LED bulb, prolongs the life-span of LED bulb.The heat that aluminium die casting radiator runner among the present invention is unobstructed, resistance is little, take away without laying dust, convection current is more.
