Abstract

The utility model relates to a lens and discloses a dual-lens of a combined LED lamp. The dual-lens of the combined LED lamp comprises an astigmatic lens and a condensing lens which are arranged back and forth in parallel, wherein the astigmatic lens is a convex lens, a plurality of convex lens units are uniformly distributed on the condensing lens, each convex lens unit comprises an LED accommodating space arranged on one side of the condensing lens, a spherical incident plane on the surface of the accommodating space, and a spherical emergence surface protruded on the other surface of the condensing lens, and the spherical incident plane and the spherical emergence surface form a convex lens, of which the focus point is positioned on the LED inside the accommodating space. The dual-lens of the combined LED lamp has the advantage that a plurality of low power LEDs can exert lighting effect which is the same with that exerted by a high-power LED.

Description

The double lens of Combined Led Light Up

Technical field

The utility model relates to lens, especially relates to a kind ofly making many low-power LEDs launch the double lens with the Combined Led Light Up of a same light efficiency of great power LED.

Background technology

Under the segmentation of LED illuminating industry, be divided into great power LED and low-power LED.Generally, the present LED illumination of adopting is to adopt high-power electricity-saving lamp product as light source more than 90%.The power that so-called great power LED just is meant single light emitting diode is more than or equal to 1W.Although it is still slightly inferior that the great power LED product than conventional illuminating product energy-saving and environmental protection, is compared with the low-power LED product, many core technologies are demanded urgently breaking through.It is reported that the conversion of great power LED light efficiency is not high, only about 50%-60%, a large amount of power consumptions are on radiator, and this installs heat sink from needs and just can find out.On actual installation, great power LED also exists problems to wait to solve.In addition, aspect energy-conservation, be standard with 20 watts of 6 meters high low-power LED lamps, brightness is equivalent to 400 watts of incandescent lamps, if reach same brightness, high-power LED needs 40 watts, low-power LED is saved the energy more than one times than great power LED.Moreover, low power performance also is remarkable, and is still keeping the record that zero dimension is repaiied in the installing engineering product so far.

But use many low-power LEDs as illumination, the dispersed light that light source is variegated, lighting effect is relatively poor.

Summary of the invention

For overcoming above-mentioned shortcoming, the utility model purpose is to provide a kind of makes many low-power LEDs launch the double lens with the Combined Led Light Up of a same light efficiency of great power LED.

The utility model is realized through following technical measures; A kind of double lens of Combined Led Light Up; The astigmat and the collector lens that are arranged in parallel before and after comprising; Said astigmat is convex lens; Said collector lens is one to be evenly distributed with the lens of a plurality of convex lens unit, and said convex lens unit comprises a LED accommodation space that is arranged on the collector lens one side, the sphere plane of incidence and the protruding sphere exit facet at the collector lens another side on accommodation space surface, and the said sphere plane of incidence and sphere exit facet are formed focus convex lens on the LED in accommodation space.

As a kind of optimal way, said astigmat is a hemisphere, said collector lens be one with the corresponding disc of hemisphere.

All post or scribble anti-reflection film as said astigmat of a kind of optimal way and collector lens surface.

The preferred light transmittance of said astigmat and collector lens is greater than 93% optical glass lens or PMMA lens.

The point light that many low-power LEDs of the utility model send is injected in the collector lens in the convex lens unit of collector lens; Outgoing becomes directional light; The parallel again astigmat of injecting; The light efficiency of the light that penetrates from astigmat is that the focus from astigmat penetrates, thereby the light that many low-power LEDs are sent produces the effect of the light that a great power LED sends.

Fig. 2 is the vertical section structural representation of the utility model embodiment convex lens unit;

Fig. 3 is the structural representation of looking up of the utility model embodiment collector lens.

The specific embodiment

Below in conjunction with embodiment and contrast accompanying drawing the utility model is done further explain.

Like Fig. 1, Fig. 2, Fig. 3, a kind of double lens of Combined Led Light Up, the optical glass astigmat 1 and the optical glass collector lens 2 that are arranged in parallel before and after comprising.Astigmat 1 is hemisphere convex lens; Collector lens 2 is one to be evenly distributed with the disk of a plurality of convex lens unit; Each convex lens unit comprises a LED accommodation space 201 that is arranged on collector lens 2 one side, the sphere plane of incidence 202 and the protruding sphere exit facet 203 at collector lens 2 another sides of accommodation space 201 inner surfaces, and the sphere plane of incidence 202 is formed focuses convex lens on the LED in accommodation space 201 with sphere exit facet 203.

The point light that many low-power LEDs in the LED accommodation space 201 send is injected in the collector lens 2 in the convex lens unit of collector lens 2; Outgoing becomes directional light; The parallel again astigmat 1 of injecting; The light efficiency of the light that penetrates from astigmat 1 is that the focus from astigmat penetrates, thereby the light that many low-power LEDs are sent produces the effect of the light that a great power LED sends.

More than be that the double lens of the utility model Combined Led Light Up is set forth; Be used for helping to understand the utility model; But the embodiment of the utility model is not restricted to the described embodiments; Anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify, all should be the substitute mode of equivalence, be included within the protection domain of the utility model.
