Background technology
LED is the abbreviation of Light Emitting Diode (light emitting diode), belongs to a kind of compound semiconductor element, electric energy can be converted into light.Advantages such as LED has luminous efficiency height, environmental protection, the life-span is long, volume is little are state-of-the-art in the world at present lighting engineering.Along with the develop rapidly of LED technology, the fast lifting of large power white light LED luminous efficiency, LED illumination (also claiming semiconductor lighting) is described as another revolution of lighting field.
Road lighting is brand-new, a huge market for LED, and the heat that LED produces during because of its work is less, and luminous efficiency is higher, is called as cold light source.The LED street lamp is made up of substrate, lens and cooling system etc., compares with fluorescent lamp with traditional incandescent lamp, and its electric energy can reach more than 90%.Yet, hinder LED large-scale application in road lighting at present, also be its technology.The application of LED illumination runs into a lot of difficult problems, and one of them is exactly how to reduce light decay, prolongs the service life of LED.
Though LED is a cold light source, but still can produce heat at work.The LED operating temperature generally should be less than 50 ℃.Have data to show: the life-span of temperature 1ed when 85 spend is 70,000 hours, but the life-span but has only 50,000 hours when temperature rises to 95 when spending, and it is 2.5 ten thousand hours in the life-span when spending that temperature rises to 115.At present the cooling system of LED street lamp also is not very perfect, applies stumbling-block in the process to become it, and is even more serious for this situation of middle high power street lamp, so heat dissipation technology has become one of direction of person skilled research.
Solving heat dissipation problem mainly starts with from three aspects.Be the photoelectric transformation efficiency that begins to improve wafer from the source on the one hand; Be to start with from encapsulation with reducing the thermal resistance of encapsulation on the one hand; Be to start with at application product with improving the heat-sinking capability of product on the one hand.It is heat energy with regard to the power conversion that 800mw is arranged that the luminous efficiency of the wafer of present main flow just consumes each watt electric energy about 130lm/w (about 200mw) greatly, so heat dissipation problem still is an emphasis.The method that solves heat radiation at present mainly is to adopt the mode of natural air convection current.This mode needs radiator to have and enough big area of dissipation and air bleed capability preferably.
The utility model content
The technical problem that the utility model solves is the deficiency that overcomes existing heat dissipation technology, and a kind of simple in structure, good heat dissipation effect, the LED illuminating lamp heat radiation module that effectively increases the service life and the heat abstractor of being made up of this heat radiation module are provided.
The technical scheme that the utility model adopted is: LED illuminating lamp heat radiation module, it is characterized in that forming by heat radiation backboard, metal fin and metal catheter, described metal catheter links together described heat radiation backboard and metal fin, the medial surface of described metal catheter is connected with described heat radiation backboard, the outside of metal catheter is connected with metal fin, and the inner surface of described heat radiation backboard closely contacts with the medial surface of described metal fin.
Be provided with several metal fins and several heat radiation conduits, all metal fins are arranged in parallel, and form the space of heat radiation between the adjacent metal fin.
Described metal catheter is a closed ring, and the heat radiation backboard is provided with draw-in groove, and a side of metal catheter is fixed in the draw-in groove, and another side of metal catheter is connected with metal fin.
Described metal catheter is to be made up of two symmetrically arranged " U " shape pipes, and the heat radiation backboard is provided with draw-in groove, and a side of metal catheter is fixed in the draw-in groove, and another side of metal catheter is connected with metal fin.
LED illuminating lamp heat abstractor, it is characterized in that forming by heat radiation module, substrate, led light source, transparent housing, collision mat, described heat radiation module is made up of heat radiation backboard, metal fin and metal catheter, described metal catheter links together described backboard and metal fin, the medial surface of described metal catheter is connected with described backboard, the outside of metal catheter is connected with metal fin, and the inner surface of described heat radiation backboard closely contacts with the medial surface of described metal fin; Described substrate links to each other with the backboard of heat radiation module, and led light source is installed on substrate, in the arranged outside of substrate collision mat is arranged, and in the arranged outside of collision mat transparent housing is arranged, and described transparent housing is connected with substrate.
The beneficial effects of the utility model are: described heat radiation module comprises heat radiation backboard, several metal fins, several metal catheters, described metal tube is closed and is connected between described backboard and the metal fin, top and the described backboard of described metal catheter closely is connected, and navigates within below between described several metal fins.The inner surface of described heat radiation backboard closely contacts with the upper surface of described metal fin.The heat that such structure produces when making LED street lamp, stage lighting work passes to described metal fin by described backboard, described metal catheter, and reject heat in the external environment by the described back cover of metal manufacturing, make LED street lamp, stage lighting residing temperature when operation be lower than 50 ℃, the light decay of having avoided LED at high temperature to work and caused has for a long time effectively prolonged service life of LED street lamp, stage lighting.
Because several described metal fins of the present utility model are parallel to each other, form the space of heat radiation between adjacent described metal fin.It is relative more smooth and easy that this structure makes that described back cover and air in the chamber that described front shroud surrounds flow, and helps heat radiation, so radiating effect of the present invention is better.
Because described metal catheter of the present utility model is closed and is connected between described backboard and the metal fin, the top and described backboard of described metal catheter closely is connected, and navigates within below between described several metal fins.Such structure has been accelerated the speed of heat radiation, helps heat radiation, so radiating effect of the present utility model is better.
Because the design of described metal catheter of the present utility model can realize mode that liquid phase-change conducts heat the heat of thermal source is transmitted on each fin, such design reduces the weight and volume of radiator greatly, and accelerated the speed of heat radiation, help heat radiation, so radiating effect of the present invention is better.
