The specific embodiment
Embodiment one
As depicted in figs. 1 and 2, be the structural representation of LED lens module one preferred embodiment of the present invention and the generalized section of A-A line segment thereof respectively.From shown in the figure as seen: this LED lens module that has multi-angle combination that is used for the LED street lighting mainly is to be made of lens mount 1 and the lenticular body 2a that makes with transparent PC or PMMA, quantitatively is far above one one group or some groups of lenticular body sealing pastes and is contained in that permutation and combination is integral on the lens mount 1.Other comprises emitting led with quantity such as this lenticular body 2a, is assembled in the inside of lenticular body 2a respectively correspondingly.Wherein, among each lenticular body 2a of this group of lenticular body, single or part has focal length angle (lenticular body real focal length point is with respect to the angle of central shaft deflection) and the curvature (degree of crook of lenticular body itself) that is different from other lenticular body 2a.According to the demand of lens luminous intensity distribution, this group of lenticular body matrix form is arranged in the surface of lens mount 1, and each lenticular body 2a by the difference of focal length angle and curvature separately by around the mind-set in the lens mount gradually the degression type combination arrange.For obtaining softer light distribution effect, in LED lens module production preparation process, focal length angle between the adjacent lens body and curvature need be changed two homogenising.
In the above-mentioned LED lens module, this lenticular body 2a middle part is provided with the cylindrical pit that an end face is a cambered surface, and each LED light emitting source is respectively to be installed in correspondingly among these pits, and constitutes the plane of incidence of led light source irradiation with the hole wall of pit.On the wherein same LED lens module, the shape of each pit does not have unicity, and its end face can be the cambered surface (as shown in Figure 2) that goes up convex, can be the cambered surface of concavity down, can be plane completely yet.In addition, this pit more can be the semicircle sphere, obtains different focal length angle and the curvature of lenticular body 2a with multifarious pit form like this.
In addition, in the above-mentioned LED lens module, around this lens mount also respectively quantity be provided with plural number alternatively locating hole 11 be installed.Go so that this LED lens module is installed in the road lighting road lamp system with modular form, and when breaking down, can dismantle quickly and easily, change.Certainly, it installs locate mode is various optional, comprise be spirally connected, multiple modes such as elasticity riveted joint, sticker are all applicable.
Embodiment two
As shown in Figure 3 and Figure 4, be the structural representation of another embodiment of LED lens module of the present invention and the generalized section of B-B line segment thereof respectively.From shown in the figure as seen: the architectural feature that this LED lens module that has multi-angle combination that is used for the LED street lighting is different from embodiment one is: this LED lens module is made of lenticular body 2b and lens mount 1 integrated assembling, this sphere shape lenticular body 2b is different from the rectangle of embodiment one in shape, and all there is significant difference in those lenticular bodies 2b with the lenticular body 2a shown in the embodiment one on the tightness degree and arrangement mode of lens size, permutation and combination.Herein, the arrangement architecture of those lenticular bodies 2b is that polygon determinant is arranged, and the lenticular body 2b distribution in delegation or is listed as arbitrarily is uniform.As seen by shown in Figure 4, in the present embodiment, the shape and the embodiment one of the set pit of this lenticular body 2b are roughly the same, only the variation of cylinder diameter existence.
What difference above-mentioned two embodiment no matter lenticular body shape or arrangement architecture exist, but all for the design of a general character: the focal length or the curvature lens inequality that promptly adopt a plurality of different angles, integrated permutation and combination constitutes a complete LED lens module on lens mount.And the difform pit design of scioptics body, the different photodistributed LED that can arrange in pairs or groups can't exert an influence to spotlight effect.
In addition, this LED lens module can also cooperate the light fixture mechanism design to become waterproof construction, can be further perfect to the application of street lighting under the overcast and rainy environment of open-air atmosphere.
In this programme, its lens numbers is generally one group of 3-30 or is divided into some groups, and the led light source power that module can be supporting is about 3-30W, arranges at grade symmetrically.The focal length of described lenticular body lens mount or curvature are made up to the mode of successively decreasing gradually all around by module centers, and lens mount focal length or curvature between the adjacent lens module become even variation, and good excessive ratio is arranged.
After adopting this lens, it is wing that its distribution curve flux is bat, and each section is different incomplete same because of need, make hot spot rectangular and can rationally control distribution of light, and light extraction efficiency is greater than 75% in effective irradiation area, total light transmittance has farthest reduced the loss of light greater than 90%, and the light that light source is sent is fully utilized; In addition, illumination is very even in effective irradiation area.The hot spot edge clear, effectively irradiation area does not almost have veiling glare outward, do not have bad dazzle, can not cause light pollution: can be widely used in road lighting, advertisement light projector etc. has the lighting field of specific (special) requirements to the field of illumination, is the illuminating product of a kind of green, energy-saving and environmental protection.
To sum up, the present invention is not subjected to the restriction of lens exiting surface shape, and no matter the exiting surface of lens is plane or curved surface, takes technical solution of the present invention all can obtain more satisfactory effect.In addition, those skilled in that art can know by inference, and technical solution of the present invention is not subjected to the application restriction of above-mentioned " street lamp " this example.In fact, the led light source that all this kind of employing modes dispose, no matter make street lamp with it, still make other various lightings with it, all can use technical solution of the present invention improves the rising angle of lens, thereby eliminate problems such as focused beam dazzle, astigmatism, improve the result of use of these illuminations.
