Description
Technical field
The utility model relates to the radiator of using in the used LED light fixture in a kind of light of stage, TV, film and studio.
Background technology
That optical diode (LED) possesses is frivolous, power saving, environmental protection, light the characteristics such as reaction is fast, long-life, add cost is continuous fall under, light output still constantly promotes with power, impel the market acceptance of LED illumination to grow with each passing day, from the traffic sign indicator lamp to large area backlight, proceed to various lighting uses such as headlight, indoor and outdoor lighting light fixture etc.Present stage LED luminous efficiency has broken through every watt of 100 lumens, is enough to replace incandescent lamp, the Halogen lamp LED of power consumption, or even fluorescent lamp and high-voltage gas discharging light.At present, high-power LED light source is divided into two kinds, and a kind of is array distributed, and a kind of is integrated high-power LED light source.Wherein, integrated high-power LED light source is the direction of Future Development.Be accompanied by the high-capacity LED technology and repeatedly get along with, the LED size is dwindled gradually, and heat concentrates in the small-size chips, and heat density is higher.High temperature can cause the photon of chip outgoing to reduce, the colour temperature Quality Down, and chip is aging to be accelerated, and will significantly reduce LED light efficiency, life-span even burns short time Inner oneself.
Reduce the LED thermal resistance, its heat radiation relates to chip level (Chip Level), encapsulation level (Package Level), heat-radiating substrate level (Board Level) to the heat dissipation design of each level of systemic hierarchial (System Level).
Heat radiation strategy for system end, common radiating subassembly is fin or fin (Heat Sink), heat pipe (Heat Pipes), temperature-uniforming plate (Vapor Chamber), loop hot-pipe (Loop Heat Pipe, LHP) and piezoelectric fan (Piezo Fans).Wherein, radiating fin is used the most universal.
Radiating fin mainly is to dispel the heat by conduction and free convection mode, be modal radiating mode, utilizing increases area of dissipation and collocation air channel, open pore design, promote conduction and free convection ability, shortcoming is: (one) is that the aluminium flake of dense arrangement easily accumulates dust, stop up the gap between the aluminium flake, cause atmosphere draught-free and finally lose heat sinking function.(2) be that aluminium flake is thin and soft, as easy as rolling off a log because touching distortion or folding, affect heat sinking function and attractive in appearance.Therefore, radiator must have firm shell protection, be not suitable for directly exposing, but the existence of protecting sheathing often reduces again its radiating efficiency.
The aluminium section bar of many radiating fins moulding is extruding hot mastication aluminium alloy forming material, and this mode of production has limitation to shape need, and radiating fin can not be too thin oversize, so the LED to lower calorific value (below 150 watts) uses in being only suitable for.The leading indicator of estimating a fine aluminium radiator is thickness and the Pin-Fin ratio of foot of radiator.Pin refers to the height of the fin of fin, and Fin refers to the distance between two pieces of adjacent fins.Pin-Fin than be height (not containing base thickness) with Pin divided by Fin, Pin-Fin is larger than the efficiently radiates heat area that means more greatly radiator, represents the aluminium extrusion technology more advanced.But only consider that it is inadequate increasing the efficiently radiates heat area.When the heat radiation given volume, increase the efficiently radiates heat face, will reduce thermal resistance, be conducive to heat radiation; But also increase unavoidably flow resistance simultaneously, reduce the fluid by radiator, hinder heat radiation.Therefore thermal resistance and flow resistance must be balancedly considered in design.
The advantage of pack alloy radiator is itself to be the alloy that presses solidly, and can mould external form more attractive in appearance, needn't add shell again.Shortcoming is that the coefficient of heat conduction of pack alloy is lower than extruding aluminium alloy, and is bulky and weigh, and is fit to low-power LED lamp or distributing high-powered LED lamp and uses.
In addition, the radiator fins of existing market main flow all is the quadrangle of standard in shape, but also has portioned product to have own unique profile, wherein has take Korea S and thinks the people as the circular radiator of representative, also has the tower heat sink take Tt as representative.These radiators are for different capacity, the LED of different sizes etc., and different size is made in die sinking respectively, has increased production cost.
