Description
Technical field
The utility model relates to a kind of LED lamp, relates in particular to a kind of LED lamp with active heat removal function.
Background technology
The led light source product saves money again than white incandescent lamp power saving 90% because of it is energy-conservation; Life-span is 50 times of conventional bulb, and price is 50% of highly sophisticated products of the same trade, and LED is a photoelectric device; Enjoy great popularity because of it is energy-conservation, economical, utility time is long this year; In the course of work of LED, have only the electric energy of 15%-25% to convert luminous energy to, remaining electric energy nearly all converts heat energy to, and the temperature of LED is raise.In great power LED, heat radiation is a big problem.For example: 1 10W white light LEDs is if its photoelectric transformation efficiency is 20%; Then the electric energy of 8W converts heat energy to again; 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 lamp with active heat removal function.
The utility model content
The utility model technical problem to be solved is: a kind of LED lamp with active heat removal function that increases the service life is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of LED lamp with active heat removal function, and it comprises: shell; The upper end of said shell is equipped with power supply unit, and the below of said shell is equipped with fan, aluminium die casting radiator is installed below the said fan; The below of said aluminium die casting radiator is equipped with the LED aluminium base; Said LED aluminium base is equipped with led light source, and the below of said LED aluminium base is equipped with optical lens, and said aluminium die casting radiator comprises base portion and several radiating fins that protrude out from base portion; Form runner between per two radiating fins; The central authorities of said base portion are provided with air inlet, and the circumference of said base portion is provided with equally distributed several air outlets, and said air outlet and runner connect; The central authorities of said LED aluminium base are provided with and corresponding first through hole of air inlet, and the central authorities of said optical lens are provided with and corresponding second through hole of air inlet.
The beneficial effect of the utility model is: air gets into from the air inlet in the middle of the aluminium die casting radiator, makes the inner pressure reduction that forms of lamp body, and air is discharged from air outlet along runner, and forms circulation, thereby takes away the heat in the LED lamp, prolongs the life-span of LED lamp.The heat that aluminium die casting radiator runner in the utility model is unobstructed, resistance is little, no laying dust, convection current are taken away is more.
