Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1-Figure 3, Fig. 1 is the utility model collector lens group structural representation; Fig. 2 is collector lens group side view in Fig. 1, and Fig. 3 is the generalized section of collector lens group A-A section in Fig. 2.A kind of collector lens group 1 that this embodiment proposes, carry out luminous intensity distribution for the light that LED light source is sent, described collector lens group 1 comprises lens mount 11, described lens mount 11 comprises the first plane 112 and the second plane 111 that opposing parallel arranges, described the second plane 111 convexes with several lens body 12, wherein, described the first plane 112 is incidence surface, and the surface of described lens body is exiting surface 121.In the time that the light that LED light source sends is radiated on incidence surface 112, described incidence surface 112 is accommodated the light that LED light source sends, described light enters in lens body 12 after incidence surface 112 reflects for the first time, then after reflecting for the second time, exiting surface 121 penetrates, described exiting surface 121 is smooth surface, accurately the exit direction of described light is corrected in polymerization, so that the shooting angle of light diminishes.Described set of lenses can meet for example, demand to multiple lighting angle (: 15 °, 30 °, 60 °, 100 ° etc.) of user.The collector lens group 1 that the utility model provides, carries out accurate luminous intensity distribution for the light that LED light source is sent, and has reduced the production cost of conventional package optical lens LED, has also increased production efficiency; Secondly, can also provide the set of lenses with different lighting angles, avoid the LED lighting angle of encapsulating optical lens single, need to encapsulate the situation of different optical lens.In addition, collector lens group of the present utility model has been avoided contacting with the direct of LED, is beneficial to the heat radiation of LED, has extended the service life of LED.
Further, described lens mount 11 is one-body molded with described lens body 12.Should be understood that, described set of lenses 1 can be one-body molded, also can be lens mount 11 and lens body 12 split settings, then lens body 12 is fixedly connected with described lens mount 11, but the set of lenses 1 of split setting can cause light losing, so collector lens group 1 of the present utility model is preferably one-body molded.
Further, the light that LED light source sends is after incidence surface 112 enters lens body 12, most of light penetrates after exiting surface 121 polymerizations are corrected, but some light can penetrate by the second plane 111, because the second plane 111 does not have spotlight effect, the light penetrating through the second plane 111 disperses, and can not assemble, and has so just weakened the illumination of illuminated area; In order to reduce the dispersion of light, improve the illumination of light at illuminated area, on described the second plane 111 top layers, reflector layer (not marking in figure) is set, light is reflected back after being irradiated to reflector layer, has so just avoided light to scatter from 111 points, the second plane.
Further, described collector lens group 1 is bar shaped setting.Be understandable that, described collector lens group 1 can also be rounded or square, is designed to various shapes according to the actual needs of light fixture, is not limited to certain shape herein.
In addition, optical lens generally comprises silica-gel lens, methyl methacrylate (PMMA) lens, Merlon (PC) and glass lens.Silica-gel lens, because its resistance to elevated temperatures is good, is usually used in packaged LED, and methyl methacrylate (PMMA) lens and Merlon (PC) lens can be produced by injection moulding, and production efficiency is high, and light transmission is good, but resistance to elevated temperatures is poor; Glass lens light transmission is good, and resistance to elevated temperatures is good, but glass lens quality is large, frangible, at the bottom of production efficiency, cost is high.In view of the pluses and minuses of above-mentioned several optical lenses, the utility model preferable methyl methyl acrylate (PMMA) lens or Merlon (PC) lens.
Further, as shown in Figure 4, the utility model also provides a kind of light fixture, comprises housing unit, and described housing unit includes the diffuser 2 and the light fitting body 6 that mutually hold and surround bar-shaped fluorescent tube, described light fitting body 6 is equipped with lamp plate 4, LED lamp grain 3 is installed on lamp plate 4, and described light fixture also comprises a kind of collector lens group 1, and described collector lens group is arranged at described housing unit inside, concrete structure about collector lens group 1 can be with reference to noted earlier, and therefore not to repeat here.
Particularly, because the light part that LED light source sends is understood directive lamp plate 4, for fear of the loss of light, the one side that is provided with lamp grain at lamp plate 4 is provided with reflector layer (not marking in figure), like this, in the time that light is radiated on lamp plate 4, reflector layer can be gone out light reflection, then accommodate through incidence surface 112, finally penetrate through exiting surface 121.
Further, light fitting body is provided with the first installing plate 5 and the second installing plate 7, be used for installing diffuser 2 and collector lens group 1, the first installing plate 5 and the second installing plate 7 are oppositely arranged, and be fixedly connected with or removably connect with described light fitting body 6, for example, the first installing plate 5 and the second installing plate 7 can be welded on described light fitting body 6, also can be fixed by screws on described light fitting body 6.
Particularly, the outside of the outside of the first installing plate 5 and the second installing plate 7 is provided with projection (not marking in figure) or groove (not marking in figure), diffuser 2 is provided with the groove (not marking in figure) or the projection (not marking in figure) that coordinate with described the first installing plate 5 and the second installing plate 7, and diffuser 2 is installed 7 plates with the first installing plate 5 and second and held and be connected with groove by projection.Be understandable that, diffuser 2 should have certain elasticity, and in the time installing or dismantle diffuser 2, diffuser 2 can produce certain deformation, facilitates like this installation and removal of diffuser 2.
Further, the medial surface that the first installing plate 5 is relative with the second installing plate 7, and second install the 7 plates medial surface relative with the first installing plate 5 and be equipped with groove (not marking in figure), set of lenses 1 scioptics base 11 and holding of described groove are fixed on the first installing plate 5 and the second installing plate 7.When described set of lenses 1 is installed, the lens mount 11 of set of lenses 1 can be inserted in described groove, in the time that user changes the set of lenses 1 of other angles as required, only need extract set of lenses 1 out, like this, the installation of set of lenses 1, dismounting and change just very convenient.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
