As Fig. 1, Fig. 2 and shown in Figure 3.The LED lens module that a kind of even face is luminous, comprise: led light source 20, be configured in the lens 40 of led light source 20 tops and be placed in the lens carrier 30 of lens 40 inboards and be positioned at the diffusion sheet 50 of lens 40 tops, wherein lens 40 have first plane of incidence 101, second plane of incidence 102, first reflecting surface 103, second reflecting surface 104 and exiting surface 105, wherein, 103 types of the medial surface 31 of lens carrier 30 and first reflecting surface are identical, the light that led light source 20 sends, a part arrives second reflecting surface 104 via described first plane of incidence 101, another part arrives exiting surface 105 via described second plane of incidence 102, after above-mentioned light will be pooled to first reflecting surface 103, carry out outgoing by exiting surface 105 and diffusion sheet 50 again.
Further, in this programme, ray1 and ray2 also may be behind several secondary reflections of process between exiting surface 105 and first reflecting surface 103, finally from exiting surface 105 outgoing.The light that led light source 20 sends, a part of light shown in ray1, behind described first plane of incidence, 101 arrival, second reflecting surface 104, is perhaps beaten after 103 reflections of first reflecting surface directly from exiting surface 105 outgoing; Perhaps between first reflecting surface 103 and exiting surface 105, pass through several secondary reflections, finally from exiting surface 105 outgoing.
Another part light is after 102 incidents of described second plane of incidence, perhaps shown in ray2, behind the arrival exiting surface 105, behind first reflecting surface, 103 reflection one or many, from exiting surface 105 outgoing; Perhaps light is directly beaten at first reflecting surface 103 after 102 incidents of second plane of incidence, again through behind first reflecting surface, the 103 reflection one or many, from exiting surface 105 outgoing.From the light of exiting surface 105 outgoing, by diffusion sheet 50, obtain even exiting surface again.
As shown in Figure 1, the LED lens module that a kind of even face is luminous comprises: led light source 20, be configured in the lens 40 of led light source 20 tops and be placed in the lens carrier 30 of lens 40 inboards and be positioned at the diffusion sheet 50 of lens 40 tops.
As Fig. 2, Fig. 3 and shown in Figure 4, wherein lens 40 have first plane of incidence 101, second plane of incidence 102, first reflecting surface 103, second reflecting surface 104 and exiting surface 105, wherein, 103 types of the medial surface 31 of lens carrier 30 and first reflecting surface are identical, the light that led light source 20 sends, a part arrives second reflecting surface 104 via described first plane of incidence 101, another part arrives exiting surface 105 via described second plane of incidence 102, after above-mentioned light will be pooled to first reflecting surface 103, carry out outgoing by exiting surface 105 and diffusion sheet 50 again.
Therefore, in the utility model embodiment, as shown in Figure 4, and the light that led light source 20 sends, a part of light 1 arrives second reflecting surface 104 via described first plane of incidence 101, and then reflexes to first reflecting surface 103; Another part light 2 arrives exiting surface 105 reflected back first reflecting surface 103 again via described second plane of incidence 102, and above-mentioned light 1 and light 2 carry out outgoing by exiting surface 105 and diffusion sheet 50 again after arriving first reflecting surface 103.
Further, in this programme, led light source 20 can use 1W ~ 3W great power LED as light source.
Further, in this programme, lens 40 can be resin lens, and constituent material includes but not limited to PMMA or PC, and lens 40 have first plane of incidence 101, second plane of incidence 102, first reflecting surface 103, second reflecting surface 104 and exiting surface 105.Wherein, be coated with one deck minute surface high-reflecting film on second reflecting surface 104.In the present embodiment, lens 40 thickness can be 7mm ~ 10mm, and the diameter of exiting surface 105 is about 50mm, and the maximum gauge of second reflecting surface 104 is about 10mm.
Further, in this programme, as shown in Figure 3, the medial surface 31 of lens carrier 30 is identical with 103 types of first reflecting surface of lens 40, from the light of first reflecting surface, 103 transmissions, and will be through the medial surface 31 of lens carrier 30, enter into lens 40 again, continue light and propagate.Lens carrier 30 can perhaps be used PC, ABS injection moulding with the direct injection mo(u)lding of high anti-plastics, and the medial surface 31 of lens carrier 30 dusts or is coated with one deck white paint, and the powder of employing and white paint can be high diffuse-reflective material.
Further, in this programme, diffusion sheet 50 thickness can be 1mm ~ 2mm, and its thickness is more thin, and then the structure of a LED lens module that even face is luminous is then more compact, as shown in Figure 5, comprises incidence surface 51 and exiting surface 52.And, even in order to control exiting surface 105 brightness, can be in the incidence surface 51 of diffusion sheet 50 some white diffuse reflection printing points of arranging.Because the light that some comes out from lens 40, do not beat on the medial surface 31 of lens carrier 30, but directly get to diffusion sheet 50 back outgoing, so difficult realization of brightness homogeneous of whole module, and the printing points on the incidence surface of diffusion sheet 50, light can be reflexed to again on the medial surface 31 of lens carrier 30, just can control this part light, can be too not bright.
Therefore, this programme can be achieved as follows optical effect, because the center of the exiting surface 105 of lens 40 is second reflectings surface 104, so this part zone does not have light to come out, all brightness is even on other zone of exiting surface 105, so human eye is seen over, is the even exiting surface of an annular.
Above-described embodiment is exemplary, and does not wish that they limit technical method of the present utility model.Though describe the utility model in detail with reference to preferred embodiment; but be understood by those skilled in the art that; can under the situation of the spirit that does not depart from the utility model technical method and category, revise or be equal to and replace technical method of the present utility model, these modifications and be equal to the protection category that replacement also belongs to the utility model claims.
