[specific embodiment]
For further detailed elaboration technical scheme of the present invention, be elaborated below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2; The invention discloses a kind of LED light-emitting device; Comprise whirligig 1 and be installed in the LED light emitting module 2 on the whirligig 1; Said whirligig 1 has a rotating shaft 10 (rotating shaft is an entity, is not the virtual axis of rotation on the mathematical concept), and said LED light emitting module 2 is installed on the rotating shaft 10.Whirligig 1 can be selected direct current generator for use, and the LED light emitting module 2 of this moment is installed on the turning cylinder of direct current generator.
The present invention adopts whirligig 1 to drive LED light emitting module 2 rotation at a high speed, and low-power LED light emitting module high speed rotating mould capable of using is drawn up the effect of high-power illumination, and the rotation of high speed has simultaneously also solved the heat dissipation problem of LED light emitting module itself.Novel structure of the present invention designs ingeniously, can significantly cut down the cost of LED illumination, help to promote comprehensively popularizing of LED illumination, and be preferred option low-cost, the high efficiency illumination design.
LED light emitting module 2 of the present invention can be the white light LEDs light emitting module; The rotation at a high speed under the drive of direct current generator of LED light emitting module 2 this moment; Low power light emitting module capable of using simulates high-power illuminating effect, and the light-emitting area 20 of LED light emitting module 2 will utilize the collimation error to form the light-emitting area of a full circle at this moment.The big or small visual concrete condition of the rotating speed of direct current generator of the present invention and LED light emitting module 2 is carried out rational allocation, finally simulates the hot spot effect of uniform.
The light emitting module 2 of LED of the present invention also can be selected RGB (red, green, blue) three-primary color LED light emitting module for use; RGB three-primary color LED light emitting module is being mixed into white light after the rotation at a high speed under the drive of motor; Light loss consumption when having avoided traditional led chip excitated fluorescent powder; Improve the utilization rate of the effective light of led chip, reduced the product cost of white-light illuminating.RGB three-primary color LED light emitting module is appreciated that to be a light emitting module, and this moment, RGB three-primary color LED or led chip can be distributed on the same circumference according to replacing corresponding relationship, and the present invention preferably adopts the structure of the integrated encapsulation of COB.Certainly RGB three-primary color LED light emitting module also can be respectively glow, three luminous plaques of green glow, blue light, as shown in Figure 5, the RGB three-primary color LED light emitting module of this moment can be that integral structure also can be three modular structures of light emitting module.
As shown in Figure 1, LED light emitting module 2 of the present invention can be " one " font; Also can be " ten " font.LED light emitting module 2 can be provided with a plurality of; As Fig. 3, shown in Figure 4 be the combination of 3 LED light emitting modules 21,22,23 of equidistant ring array, this combination can be an integral type, also combined type; The preferred combined type that adopts is to carry out rational allocation according to actual needs.
As shown in Figure 5; In order to make LED light emitting module 2 when rotating at a high speed, simulate uniform hot spot; Greater than the width h2 near the light-emitting area of rotating shaft 10 1 ends, LED light emitting module 2b, 2c also follow above rule to LED light emitting module 2a away from the width h1 of the light-emitting area of rotating shaft 10 1 ends.
LED light emitting module of the present invention 2 is for can make a kind of or its combination in fan-shaped, trapezoidal or the triangle, and is as shown in Figure 5, and being shaped as of LED light emitting module 2a, 2b, 2c is fan-shaped.
In order more effectively to solve heat dissipation problem; Can be horizontally disposed with the radiating groove or the louvre (not shown) of a plurality of perforations in the substrate of LED light emitting module 2; The opening of louvre or radiating groove should be towards the direction of the rotation of LED light emitting module 2, promptly connects louvre or radiating groove that two sides of fan-shaped light emitting module form, and a plurality of cellular ventilation slots or air vent are set in substrate increases its area of dissipation with this; Quicken cross-ventilation; Alleviate the weight of LED light emitting module 2, can promote the rotating speed of whole LED light emitting module 2, better heat radiating effect to be provided and to go out light effect.
