Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
Light harvesting lightguide of the present invention comprises at least one light element 3.Consult Fig. 2,3,4, the preferred embodiment of light harvesting lightguide of the present invention, for conducting the light of several illuminating part 21 (only illustrating in figure), each illuminating part 21 is a light-emittingdiode (LED) such as, and described illuminating part 21 is arranged on a ringwise circuit board 22.And this light harvesting lightguide entirety structure roughly ringwise, and comprise several light element 3 in flat.
Each light element 3 comprises a light guide section 4, and a light collecting portion 5.The light guide section 4 of described light element 3 is made into integration with plastic material, and be connected and form a circulus around an axis L.Each light guide section 4 is curved flat around this axis L, and comprise two along its interval, arc length direction relatively and the first close gradually from top to bottom light guiding surface 41, two along this light harvesting lightguide radial direction interval relatively and the second light guiding surface 42, be connected between described first light guiding surface 41 is connected to the guide-lighting incidence surface 43 of one end of described first light guiding surface 41 and the second light guiding surface 42, and one is connected to the other end of described first light guiding surface 41 and the second light guiding surface 42 and the guide-lighting exiting surface 44 relative with this guide-lighting incidence surface 43 interval.
Wherein, generally speaking this guide-lighting incidence surface 43, is the one end away from this guide-lighting exiting surface 44 from described first light guiding surface 41 and the second light guiding surface 42, towards this light guide section 4 inner recess and define one for this light collecting portion 5 arrange mounting groove 430.This guide-lighting incidence surface 43 has the first light inlet section 431 that one day, this light collecting portion 5 arc was dashed forward, and one is connected to this first light inlet section 431 periphery ringwise and jointly defines the second light inlet section 432 of this mounting groove 430 with this first light inlet section 431.
This guide-lighting exiting surface 44 is spaced with the direction of this guide-lighting incidence surface 43 along this axis L.This guide-lighting exiting surface 44 is rough surface, and have several be connected and around this axis L the dentalation 441 of circular array, with provide light spread atomization function.Each dentalation 441 of the present embodiment connects wherein one second light guiding surface 42 side from this exiting surface 44 extends towards the direction of another the second light guiding surface 42.The guide-lighting exiting surface 44 of described light guide section 4 is connected and forms an anchor ring around this axis L.
The light collecting portion 5 of each light element 3 is positioned at the side of this guide-lighting incidence surface 43, and is arranged at the mounting groove 430 of this light guide section 4.This light collecting portion 5 is made up of the plastic material of light-permeable, and around this axis L curved flat.This light collecting portion 5 comprises a light harvesting incidence surface 51 entered for light, and one towards the light harvesting exiting surface 52 of this guide-lighting incidence surface 43.The light harvesting incidence surface 51 of the present embodiment is planar design.This light harvesting exiting surface 52 is roughly in cambered surface and in being locally provided with outstanding structure, and this light harvesting exiting surface 52 comprises several the first light inlet section 431 towards this guide-lighting incidence surface 43 to be given prominence to, and for spreading the micro-structural 521 of atomization light.There is gap between the light collecting portion 5 of the present embodiment and this light guide section 4, and then defines one and be positioned at air layer 6 between the two.
When the present invention uses, first described illuminating part 21 is arranged at one by one light harvesting incidence surface 51 side of described light collecting portion 5.After the light of each illuminating part 21 enters in this light collecting portion 5 via each light harvesting incidence surface 51, light is collected by this light collecting portion 5, the guiding of the point-source light ray of this illuminating part 21 can be gathered into the less light of light-emitting 3 D angle.Then when light penetrates this light collecting portion 5 via this light harvesting exiting surface 52, light produces and reflects between this light collecting portion 5 and interface of this air layer 6, can enter in this light guide section 4 to make light via the first light inlet section 431 of this guide-lighting incidence surface 43 and the second light inlet section 432.The light that continues is subject to the leaded light effect of this light guide section 4, and is subject to described first light guiding surface 41 and the second light guiding surface 42 reflects (being mainly totally reflected) and penetrates towards this guide-lighting exiting surface 44.
Consult Fig. 2,4,5, because the guide-lighting exiting surface 44 of described light guide section 4 connects into an anchor ring, when therefore watching described guide-lighting exiting surface 44, a roughly ringwise luminous pattern 7 (Fig. 5 represents with dotted region) along this anchor ring can be seen.
Therefore, the present invention carries out light harvesting effect by described light collecting portion 5, can improve luminous efficiency, and makes light coordinate guide-lighting incidence surface 43 form of described light guide section 4 and enter in light guide section 4.Described light guide section 4 is then do suitable optical texture design with the luminous form of described light collecting portion 5, designed by the curvature of described first light guiding surface 41 and the second light guiding surface 42, the light of described illuminating part 21 can be reflected towards this guide-lighting exiting surface 44, and then the spot light of illuminating part 21 is directed to two-dimensional surface light source, for each light element 3, the form of its luminous pattern exiting surface 44 as guide-lighting in it, the rectangular arc light-emitting area of a two dimensional surface formula can be formed, and all light elements 3 are combined when seeing, then coordinate the light-emitting area of formation one annular.
Supplementary notes, when the micro-structural 521 of described light collecting portion 5 can make light penetrate this light harvesting exiting surface 52, help the soft light of atomization; Similarly, the dentalation 441 of described light guide section 4, also may be used for diffusion atomization light.But during the invention process, not to arrange described micro-structural 521 with dentalation 441 for necessary.
In sum, by each light element 3 for flat designs, spot light can be directed to the area source of strip, to meet user demand.The present invention can be arranged on king light periphery that a figure do not show and as secondary lamp or ornament lamp in application, and just because of light element 3 is flat, therefore convenient along this king light periphery around installation, for the light fixture of limited space, it is still quite convenient to install the present invention.Innovation structure of the present invention can produce the string light pattern of two dimension, can extend along light fixture edge, contributes to strengthening light fixture edge shape.
