Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 5, a kind of embodiment of optics module of the present invention is described in detail.The optics module of the present embodiment comprises LED light source 1 and lens 2, and the light of described LED light source 1 is through the outgoing of described lens 2.Described optics module also comprises light-blocking member 3, and described light-blocking member 3 blocks the light at incidence surface 21 edge of lens 2 described in described LED light source 1 directive at least partly.Described light-blocking member 3 is provided with the shading surface 31 around described LED light source 1, and described shading surface 31 blocks the light at incidence surface 21 edge of lens 2 described in described LED light source 1 directive at least partly.In the present embodiment, described light-blocking member 3 comprises tapered wall 37, and described shading surface 31 is the inner surface of described tapered wall 37.The light that the part light-emitting area that edge due to the incidence surface 21 of described lens 2 can only receive described LED light source 1 sends, therefore the hot spot that the light through the edge of described incidence surface 21 is formed diminishes, thus the marginal definition of the whole hot spot of described optics module is improved.In the present embodiment, described light-blocking member 3 comprises flat panel like portion and is formed at the downward sunk part of central area of flat panel like portion, and the internal face of downward sunk part is described shading surface 31.As shown in Figure 2, in the present embodiment, straight line a is the straight line through the marginal point E of the incidence surface of described lens 2 and the top edge of described shading surface 31; Straight line b is the straight line through the marginal point D of the incidence surface of described lens 2 and the top edge of described shading surface 31.Straight line a, straight line b are A and B with the intersection point of the light-emitting area of described LED light source 1 respectively.The edge that cannot be irradiated to the incidence surface of described lens 2 with the light of the straight line AB circle region c that is diameter of described LED light source 1 light-emitting area, namely described shading surface 31 blocks the light in circle region c, makes this part light cannot be irradiated to the edge of the incidence surface 21 of described lens 2.The light that the part light-emitting area that edge due to the incidence surface 21 of described lens 2 can only receive described LED light source 1 sends, therefore the hot spot that the light through the edge of described incidence surface 21 is formed diminishes, thus the marginal definition of the whole hot spot of described optics module is improved.Described shading surface 31 is E with the angle of the optical axis of described LED light source 1, and as shown in Figure 3, straight line d is the straight line parallel with the optical axis of described LED light source 1, and the angle E between straight line d and shading surface 31 is the angle of shading surface 31 and described LED light source 1.When the angle of angle E increases, the definition of hot spot along with increase, but will cause the reduction of optics module light efficiency, and as angle E < 30 °, the light efficiency of optics module is higher, but the edge of hot spot is clear not enough; And as E > 60 °, the marginal definition of hot spot is higher, but the light efficiency of optics module is lower, all can not meet the demands well.When 30 °≤E≤60 °, the edge of the hot spot of optics module is comparatively clear, and the light efficiency of optics module is also higher, namely between hot spot marginal definition and light efficiency, reaches good balance.In the present embodiment, E=45 °.It is important to note that in fig. 2, the vertical center line of the light-emitting area of described LED light source 1 is the optical axis of described LED light source 1.Described light-blocking member 3 is made up of the opaque material of insulation, such as made of plastic.Described light-blocking member 3 is provided with the support portion 32 for supporting described lens 2.In the present embodiment, described support portion 32 forms to the direction extension away from described LED light source 1 from the edge of described light-blocking member 3, is the vertical wall of annular.By arranging support portion 22, the distance between LED light source 1 and lens 2 conveniently can be controlled.Described light-blocking member 3 also comprises connecting portion 39, and described connecting portion 39 is in tabular, and described connecting portion 39 connects described tapered wall 37 and described support portion 32.Described lens 2 are biconvex lens, and namely the incidence surface 21 of described lens 2 and exiting surface 22 are all convex surfaces.Described LED light source 1 is COB light source.Incidence surface 21 one end of described lens 2 is also provided with the L-shaped ring support of cross section 29, and described ring support 29 can be made of plastics, and described ring support 29 can be connected with described lens 2 by bonding mode.Described lens 2 are arranged on described support portion 32 by ring support 29, and described ring support 29 can be connected with described support portion 32 by clamping or the mode be threaded.
As the simple deformation of above-described embodiment, described lens 2 also can be planoconvex spotlight, and namely the incidence surface of described lens 2 is planes, and its exiting surface is convex surface.
As the simple deformation of above-described embodiment, described angle E also can be 31 °, 32 °, 33 °, 34 °, 35 °, 36 °, 37 °, 38 °, 39 °, 40 °, 41 °, 42 °, 43 °, 44 °, 46 °, 47 °, 48 °, 49 °, 50 °, 51 °, 52 °, 53 °, 54 °, 55 °, 56 °, 57 °, 58 °, 59 ° or 60 °.
The present invention also provides a kind of light fixture, comprises the optics module described in aforementioned any one.
As described above, be only preferred embodiment of the present invention, is not used for limiting practical range of the present invention, and namely all equalizations done according to the present invention change and modify, and are all the claims in the present invention scope and contain, illustrate no longer one by one here.
