Abstract

The utility model belongs to the illumination equipment category, and the project is particularly raised to overcome the problems of preexisting poor light gathering effect via a single lens and low efficiency. A multi-angle combined LED lens of the utility model comprises lenses and a lenticle and has a plurality of lenses with multiple angles, the lenses and lenticle comprise an integral structure by the utilization of material with good light-penetrated performance, one of the lenses is positioned as a center and other lenses are symmetrically evenly distributed on the same circumference, the focal points of the lenses superpose on a point, and a LED light source is arranged on the point, the lenticle is composed of two pyramidal platforms, two conical platforms or two circular taper platforms, each lens is a convex lens, the convex surfaces of the lenses face the common focal point of a plurality of lenses, a cylindrical space exists behind each convex surface, a cylinder hole exists in front of a flat surface of each lens. The better illuminating effect can be obtained if only a LED luminous tube can be exactly stably fixed on the focal point of each lens, and good comment is obtained from people discerning the utility model in advance via experiments.

Description

The LED lens that have the multi-angle combination

Technical field: the utility model belongs to the light fixture class.It is specifically related to a kind of structure that has the LED lens of multi-angle combination.

Background technology: a lot of as illuminating luminophor kind, along with novel product constantly appears in development of electronic technology, they respectively have advantage, and the color that have plenty of the brightness height, has is good, also have plenty of energy saving.Occurred the great power LED luminotron in recent years,, be widely used among the society because its appearance will have a lot of new lamp types to occur.For fear of the irradiation general of light source, used single convex lens optically focused, making increases brightness in limited scope, have than obvious effects, but find still can not make full use of the energy of light source, and efficient is not high.

Summary of the invention: the purpose of this utility model is for overcoming special this programme that proposes of problem that the single lens light gathering of aforesaid usefulness can not make full use of energy of light source---have the LED lens of multi-angle combination, it utilizes the combination of lenses of a plurality of different angles, the luminous energy that light source is sent makes full use of, improve the effect of illumination, improve utilization factor energy of light source.

By as above design, the LED lens that have the multi-angle combination that the utility model proposed, it is characterized in that it has the identical convex lens of focal length of a plurality of different angles, the LED lens are by phacoid and being integral of lens combination structure, on the focus of each lens converges in a bit.

In this programme, its lens numbers is 3～50, and the centre is one, and remaining is arranged on the same circumference symmetrically.Its phacoid is constituted by the two-layer frustum of a pyramid up and down, the seamed edge number of its frustum of a pyramid be distributed in circumference on the number of lens consistent.Its phacoid is formed for two frustums of a cone up and down or two circular arc frustums, also can be that a frustum of a cone and a frustum of a pyramid are formed.The convex surface of its lens points to the common focus of all lens, and the back of phacoid is a cylindrical space, and the place ahead on each lens plane is a cylindrical hole.

Adopt this programme can embody following superiority: 1. these LED lens that have the multi-angle combination are that the range of exposures of a plurality of collector lenses is connected in flakes, have made full use of the energy that light source sends, and improve the utilization factor to energy of light source; 2. the focus of each lens should be gathered together exactly, and light source should be contained on this aspect, so this programme after the precision that has solved mould, just can guarantee the reliability and the stability of work with lens and being made of one of phacoid structure; 3. the version of the multi-angle compound lens of this programme can have bigger mobility scale, phacoid can be that two frustum of a pyramids are formed, also can be that a frustum of a cone and a frustum of a pyramid are formed, or two the frustum of a cone and two circular arc frustums form, the quantity of lens can be between 3～50, the centre has one, and the rest is to distribute symmetrically and evenly on same circumference, and the selection of concrete parameter depends on the needs; 4. as long as LED high strength luminotron just accurately, stably is fixed on the common focus of each lens can obtains good illuminating effect, these LED lens move through experiment and prove: it has simple in structure, working stability, novel form, remarkably productive and advantage that manufacturing cost is not high.

Description of drawings: Fig. 1, Fig. 2 are the structural representations that this programme has multi-angle combination LED lens.Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the structural representation of single lens.

Embodiment: the LED lens that this programme has the multi-angle combination are by phacoid 1, lens 2 are formed, its lens and phacoid are integrated, use the good material of light transmission to make, lens are convex lens, the focus that convex surface converges towards a plurality of camera lenses, its lens have one at the center, the rest distributes on same circumference symmetrically and evenly, quantity is 3～50, phacoid can be that two frustum of a pyramids are formed, also can be that two frustums of a cone or two circular arc frustums are formed, also can be that a frustum of a cone and a frustum of a pyramid are formed, the face number of its frustum of a pyramid is identical with the lens numbers of inclination, and the center line of each lens should intersect at a bit, and the focus of each lens is also answered junction at that point.Be a columniform space behind each convex surface in the phacoid, each the place ahead, lens plane is a cylindrical hole.As long as led light source can accurately stably be fixedly mounted on the focus of each lens junction, each lens is poly-in limited area separately with light, and each area light connects in flakes, therefore can obtain the illumination of greater efficiency.This preproduction the experiment proved that: these LED lens have simple in structure, working stability, novel form, remarkably productive and advantage that manufacturing cost is not high.
