According to the object of the utility model, these flexible lens have a body, it is cup-shaped structure wide at the top and narrow at the bottom, and top is provided with an exiting surface, bottom is provided with an incidence surface, and this incidence surface center is arranged with formation one accommodation space, be provided with an accommodating light emitting diode, and elasticity is adjusted the lighting effect that this light emitting diode projects, it is characterized in that: these flexible lens have an optical path and adjust means, be provided with connecing and covering on this exiting surface with this body group, and see through and shorten this optical path adjustment means and this exiting surface spacing, the intensity of illumination that this light emitting diode projects is strengthened, see through and extend this optical path adjustment means and this exiting surface spacing, the illumination range augmentation that this light emitting diode is projected.So, the light that this light emitting diode is launched produces after skew through the secondary optics refraction of this body or reflection, is subject to three optical effect that this lid forms will further change optical path direction, makes to promote lighting quality.
Wherein, bring together towards this exiting surface direction depression with a convex arc curve this incidence surface center, and form this accommodation space of coniform space structure, and the cone flank of this accommodation space is concave arc shape, this slot is flat column space structure again, and this inserting part is the flat column setting of correspondence.This exiting surface and this lid lower surface are the cellular surface texture of mutual correspondence, and this lid top surface, through cloudy surface processing, forms optimum illumination suitably to adjust optical path trend and distributes.
And these flexible lens more comprise an engaging body, this engaging body is located at this body one side, is provided with being mutually fixed with respect to a LED substrate, makes to facilitate lamp assembled.
In sum, the mode that the utility model sees through flexible this lid adjust under the exiting surface of this body and this lid surface spacing from, adjust with elasticity the degrees of offset that light that this light emitting diode launched produces between secondary optics and three optics, make projection form the illuminating effect that is suitable for each field.

Detailed description of the invention
Refer to Fig. 1,2, it is respectively schematic top plan view and the elevational schematic view of the utility model preferred embodiment.As shown in the figure, these flexible lens 1 can elasticity be adjusted light source projects illumination and light source projects scope, the difference of lighting quality is required and be applicable in various light fixture, and it has a body 10 and an optical path is adjusted means to meet each field.This body 10 is cup-shaped structure wide at the top and narrow at the bottom, and top is provided with an exiting surface 100, bottom is provided with an incidence surface 101, these exiting surface 100 centers are arranged with and form a slot 1000, and these incidence surface 101 centers are arranged with formation one accommodation space, be provided with an accommodating light emitting diode (not shown).These optical path adjustment means are provided with connecing and covering on this exiting surface 100 with 10 groups of this bodies, and see through shortening this optical path adjustment means and this exiting surface 100 spacings, and the intensity of illumination that this light emitting diode projects is strengthened.Meanwhile, see through and extend this optical path adjustment means and this exiting surface 100 spacings, the illumination range augmentation that this light emitting diode is projected.
And, one of these optical path adjustment means are disc-shaped structure lid 11, its lower surface is to arranging by exiting surface 100, and center is convexly equipped with and forms an inserting part 110, be provided with being embedded in this slot and elastic telescopic this lid 11 and these body 10 spacings, make mat change impact effect to this light emitting diode projection light of the refraction of three optics and principle of reflection and elasticity is adjusted intensity of illumination and illumination range.
See also Fig. 3～6, it is respectively the utility model preferred embodiment one body schematic diagram, body cutaway view, lid schematic diagram and lid cutaway view.As shown in the figure, this slot 1000 of this body 10 is flat column space structure, therefore relatively, this inserting part 110 is to be flat column setting, and between this slot 1000 and this inserting part 110, can relatively be provided with at least one fixture (not shown), so that this inserting part 110 is fastened in this slot 1000.
Improve the effect of former this light emitting diode optical path distribution with secondary optics principle for promoting this body 10, bring together towards these exiting surface 100 direction depressions with a convex arc curve these incidence surface 101 centers, and form this accommodation space of coniform space structure, and the cone flank of this accommodation space is concave arc shape, the light of being launched further evenly to disperse former this light emitting diode.
Moreover these lid 11 top surfaces can be through cloudy surface processing, and this exiting surface 100 and this lid 11 lower surface are the cellular surface texture of correspondence mutually, form optimum illumination distribution suitably to adjust optical path trend.As shown in Figure 7,8, it is respectively the utility model preferred embodiment one optical track figure, distribution curve flux figure, engage this body 10 when this lid 11 of compression, even when its lower surface is fitted this exiting surface 100, this light emitting diode sees through the light that projects of these flexible lens 1, will be normalization intensity of illumination and be about 1 and the concentrated illuminating effect in illumination range compare Xiang center.Otherwise, when this lid 11 of stretching and away from this body 10, even its lower surface with one apart from cover on this exiting surface 100 time, as shown in Fig. 9,10, it is respectively the utility model preferred embodiment two optical track figure, distribution curve flux figure, this light emitting diode sees through the light that these flexible lens 1 project, and normalization intensity of illumination is still about 1 illuminating effect compared with spreading to surrounding will to be illumination range.Hence one can see that, and this body 10 is larger with these lid 11 spacings, and the lighting effect that this light emitting diode projected is the illumination range of the wider model of tool, but relatively weakens average intensity of illumination.
Incidentally, these flexible lens 1 more can comprise an engaging body 12, and this engaging body 12 is to be located at this body 10 1 sides, are provided with being mutually fixed with respect to a LED substrate (not shown), make to facilitate lamp assembled.
Certainly, the above is only preferred embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
