Detailed description of the invention
Below in conjunction with Fig. 2 to Fig. 4, the structure of a kind of embodiment of ornament lamp optics module of the present invention is described in detail.Ornament lamp optics module of the present invention comprises LED light source 2 and control light parts.Described LED light source 2 is installed on substrate 1, and power to described LED light source 2 by substrate 1, described substrate 1 can be ceramic substrate, aluminium base or pcb board.Certainly, described substrate 1 also needs with driving power electrical connection, and this is the common practise of this area, without the need to repeating.Described control light parts entirety is made up of transparent material, as transparent glass, acrylic or PC etc.Described control light parts comprise incident section 31 and converge light guide section 32, wherein one end of described convergence light guide section 32 connects with described incident section 31, the other end of described convergence light guide section 32 is provided with exiting surface 322, one end that described convergence light guide section 32 is connected with described incident section 31 from it diminishes gradually to the other end, described convergence light guide section 32 is provided with and converges reflecting surface 321, and the light of described LED light source 2 enters after described convergence light guide section 32 through described incident section 31 and reflexes to the outgoing of described exiting surface 322 through described convergence reflecting surface 321 again.Described convergence light guide section 32 is tapered, and the side of described convergence light guide section 32 is described convergence reflecting surface 321.The light of described LED light source 2 is after these control light parts, and by converging the reflex of reflecting surface 321, its light beam is converged to less exiting surface 322 outgoing, and compare with prior art, when other condition is the same, its brightness can promote greatly.The side of described convergence light guide section 32 is provided with reflecting layer, such as, can be aluminium coated, becomes reflecting surface to make described side.The diffusingsurface of described exiting surface 322 for making light spread, can make from the light of described exiting surface 322 outgoing more even, soft like this.Described exiting surface 322 becomes diffusingsurface through frosted or erosion line processing.Described incident section 31 is collimation incident section, and the light of described LED light source 2 becomes parallel rays behind described incident section 31.Described incident section 31 comprises the first plane of incidence 313, second plane of incidence 312 and reflecting surface 315, the some light of described LED light source 2 enters described convergence light guide section 32 after described first plane of incidence 313 incidence, and another part light of described LED light source 2 reflects through described reflecting surface 312 and enters described convergence light guide section 32 again after described second plane of incidence 312 incidence.Described first plane of incidence 313 is just to the light-emitting area of described LED light source 2, like this, the light of the smaller angle that described LED light source 2 sends is incident from described first plane of incidence 313, described first plane of incidence 313 is the collimation plane of incidence, the light of described LED light source 2, after first plane of incidence, becomes parallel rays or less parallel light.Described second plane of incidence 312 is around described LED light source 2, and described reflecting surface 315 is collimation reflecting surface, and the light of described LED light source 2, after described reflecting surface 315, becomes directional light.Described first plane of incidence 313 and described second plane of incidence 312 surround the accommodating cavity 311 of described LED light source 2.Below in conjunction with Fig. 5, the operation principle of above-described embodiment is described: the light (b of the smaller angle that LED light source 2 sends, c, d) from just incident to first plane of incidence 313 of described LED light source 2 light-emitting area, this part light enters and converges light guide section 32 after the collimating effect of first plane of incidence 313 becomes directional light, then from exiting surface 322 outgoing after converging reflecting surface 321 reflection.Light (a of the larger angle that LED light source 2 sends, e) described incident section 31 is entered from second plane of incidence 312, reflect through reflecting surface 315 again, enter again after becoming directional light and converge light guide section 32, then from exiting surface 322 outgoing after converging reflecting surface 321 reflection.The one end connected with described incident section 31 from it owing to converging light guide section 32 diminishes gradually to the other end, and exiting surface is arranged on little one end, thus makes LED light line concentrate on less exiting surface 322 outgoing.Certainly, the concrete size of this exiting surface 322 can be selected according to actual needs.The light of described LED light source 2 is after these control light parts, and by converging the reflex of reflecting surface 321, its light beam is converged to less exiting surface 322 outgoing, and compare with prior art, when other condition is the same, its brightness can promote greatly.
The present invention also provides a kind of ornament lamp, comprises the ornament lamp optics module of above-described embodiment.Certainly, this ornament lamp also comprises the driving power for powering to described LED light source.
