Abstract
The utility model relates to a power LED illuminating device module with very high cost performance. The power LED illuminating device module has the advantages of lightness, small size, simple structure, and good consistency and can effectively satisfy the electrical properties and heat properties of the application of high-power LED; moreover, the power LED illuminating device module can be manufactured in low cost. During manufacturing, LEDs and connecting wires are firstly welded together as required spacing; then a heat conducting insulation sheet is arranged in a radiator installation groove; and then a spring lamination and the welded high-power LED light balls (including the connecting wires) are installed in the installation groove. When electricity is supplied and the power LED illuminating device module begins to work, heat generated by the high-power LED light balls can be passed to the heat conduction insulation sheet (or heat conducting cream) and then to a radiator by self heat sink; and finally heat are exchanged to the atmospheric environment through fins arranged at the two sides of the radiator.
Description
Affiliated field
The utility model is the part of energy-saving illuminator, can satisfy lighting demand under the varying environment condition by various combination.Especially have very high reliability, manufacturability and recuperability.
Background technology
At present, most on the market LED lighting devices all in various degree the heat dissipation design that has can not satisfy the light output of LED itself and the characteristic of PN junction temperature.By a large amount of evidences, the life-span of LED and light decay have relation quite closely with heat radiation, the LED life-span of perfect heat-dissipating is long, light decay little (under equal chip and the package quality), and the heat dissipation design of the power LED lighting device on the market much all can not satisfy the characteristic of LED now.And major part has all required automation equipment on making, and reliability of products will guarantee that manufacturing cost and difficulty are relatively large with equipment, and versatility is not strong, is unfavorable for the application of this type of energy-conserving product.
Summary of the invention
In order to overcome the problem of insoluble heat radiation in the LED lighting device and manufacturability, the utility model provides a kind of and can make up arbitrarily, makes simple module.Composition of the present utility model comprises radiator, LED lamp pearl, insulating heat-conductive sheet, shell fragment and connecting line.
Radiator adopts the pultrusion cross section of particular design, and radiating fin has all been designed on the substrate two sides in the cross section, and radiator adopts the aluminum alloy materials pultrusion.The heat exchange area of this structure radiator is big, can effectively improve the heat exchange efficiency of radiator under the situation of forced air flow not, satisfies the heat radiation requirement.
The positive design of radiator has large-power LED light bead that groove is installed, and has designed the groove that shell fragment is installed in the groove.Shell fragment adopts high strength, ageing-resistant, lightweight new material that elasticity is good.Shell fragment also has certain decoration functions except satisfying design function.
Large-power LED light bead is heat sink one deck heat conductive isolation sheet (or heat-conducting cream) between (or substrate) and the radiator, according to different demands two kinds of phase transformation and non-phase transformations are arranged.This heat conductive isolation sheet has good heat conductivility.Certain elasticity is arranged itself, by shell fragment the large-power LED light bead shell is applied certain pressure, be delivered to large-power LED light bead heat sink (or substrate) and heat conductive isolation sheet again, large-power LED light bead heat sink (or substrate) is fitted tightly with heat conductive isolation sheet, guarantee that the heat that large-power LED light bead produces can be delivered on the radiator by heat conductive isolation sheet rapidly, again by radiator with exchange heat in atmospheric environment.
Connecting line of the present utility model adopts all preferred metal lines of heat conduction and electric conductivity.
The utility model is 50mm in large-power LED light bead (1W) spacing, and when the radiator width was 38mm, the maximum temperature on the radiator was 38.6 ℃ (25 ℃ of environment temperatures), that is to say that the temperature rise at the great power LED that uses 1W is 13.6 ℃.When environment temperature was 40 ℃, the maximum temperature on the radiator was 59.3 ℃.
The beneficial effects of the utility model are, it has light weight, and volume is less, and is simple in structure, can effectively satisfy electrical characteristics and thermal characteristics that great power LED is used, make easyly, and cost is lower, high conformity.In various lighting environments, all can effectively use.
Description of drawings
Further the utility model is described below in conjunction with accompanying drawing.
Fig. 1 is the utility model front view.
Fig. 2 is side view (left-right symmetry).
1 radiator among Fig. 2,2 heat conductive isolation sheets (or heat-conducting cream), 3 connecting lines, 4 large-power LED light beads, 5 shell fragments.
" H " is the radiator width among Fig. 2, according to different situations value between 35～45mm.
The specific embodiment
The large-power LED light bead (4) that has welded line (3) is installed on the two-sided radiator that radiating fin arranged (1), large-power LED light bead (4) is pressed on the heat conductive isolation sheet of placing in the radiator groove (or heat-conducting cream 2) by shell fragment (5), make heat sink of large-power LED light bead (4) to fit tightly with heat conductive isolation sheet (or heat-conducting cream 2), by this pressure heat conductive isolation sheet (or heat-conducting cream 2) and radiator (1) are fitted tightly equally, make the heat conduction quick rapidly.The heat that radiator comes the heat sink transmission of large-power LED light bead again makes whole power LED device module reach thermal balance rapidly by the heat exchange of fin and air.
