Abstract
The invention relates to a lens which can filter parasitic light and enable light to be distributed evenly for an LED illuminating chip. An ellipsoid-shaped lens is provided with a triangular body-shaped lens. The invention overcomes the disadvantages and defects of enabling the LED illuminating light spot to be too small, the light distribution to be uneven and the light not to be soft of the existing LED illuminating chip, and the lens improves light distribution, regulates the size and shape of the light spot reasonably and effectively, deals with light strength scientifically and effectively and enables the light of the LED lamp to be softer and to distribute more evenly, the size of the light spot to meet the operating requirements and the light to meet the requirements of green lights in deed.
Description
Technical field:
The present invention relates to a kind of LED luminescence chip with filtering out veiling glare and making the equally distributed lens of light.
Background technology:
At present, LED illumination is the development trend of whole society's illumination (particularly road lighting), LED illumination beyond any doubt energy-efficient, its to the big positive policy of whole mankind's energy-saving and emission-reduction to actively promote effect be conspicuous.In order to make the LED lamp be used for illumination better, people add that before led chip lens satisfy lighting requirement better.Even also there is the defective of following several respects in the LED lighting engineering of using (particularly street lighting) and has contained the all-round popularization and the application of this technology like this, at present:
1, distribution of light inequality causes spot center and edge illumination difference too big, center illumination too by force, too dazzling and form light pollution (as shown in Figure 1);
2, hot spot is too little, and when being used for outdoor lighting, highway has shade between the lamp stand in the same way and can not satisfy the effect of use;
3, the rounded distribution of hot spot, the hot spot between the lamp stand can't be overlapping or very little overlapping and form shade in the same way to cause highway like this, otherwise the hot spot between the lamp stand of both sides of highway is overlapping again too many and slatterned, and can't save and the luminous environment of " green illumination " is provided for the mankind effectively;
4, light is soft inadequately.
Summary of the invention:
It is too little that the problem to be solved in the present invention overcomes existing LED illumination (particularly street lighting) hot spot exactly, the distribution of light inequality, shortcoming and defect such as light is soft inadequately, a kind of distribution that improves light is provided, rational and effective is adjusted the size and shape of hot spot, the intensity of scientific and effective processing light and make the lens of its softer astigmatism that is used for led chip and optical filtering.
Its technical scheme is as follows:
It is to be provided with triangle bodily form lens on the oval shape lens.
The beneficial effect that the present invention compared with prior art has is:
1, two of triangle bodily form lens waist limits are the straight flange lens, to guarantee that chip sends central ray and penetrates by the waist limit from straight line behind the oval shape lens base, filter out veiling glare simultaneously, the angle that light penetrates penetrates so that hot spot expands instructions for use (as shown in Figure 7) to along waist limit gradient directional divergence; The light that chip sent around the central ray penetrates along the directional divergence of oval shape lens camber line simultaneously, also filter out veiling glare simultaneously, it is higher relatively and don't lose uniform high-quality distribution of light so both to have satisfied center illumination, evenly whole with behind the light that reaches adjacent lamps a small amount of overlapping, solved the strong and weak serious uneven light pollution problem that forms owing to distribution of light, more environmental protection ground provides " green illumination " requirement without any dazzle for the mankind
2, after rays pass through lens is handled, the hot spot that forms strip is laid (as shown in Figure 8) along the direction on road surface, thereby avoided between the both sides of highway lamp stand because shade that can not be overlapping between too much overlapping waste of hot spot and the highway homonymy lamp stand, like this, the light that sends of LED street lamp has obtained more efficient use in road lighting is used;
3, light is softer after lens of the present invention are scientifically handled, thereby more can satisfy human requirement to visual environment.

The specific embodiment:
Embodiment one:
Referring to Fig. 2, present embodiment is to be provided with triangle bodily form lens 2 on oval shape lens 1.Oval shape lens 1 base is a straight flange, triangle bodily form lens 2 are the isoceles triangle bodily form, the base of triangle bodily form lens 1 is positioned on the oval shape lens 1, two waists of triangle bodily form lens 1 are positioned at the middle part of oval shape lens 1, triangle bodily form lens 2 uprightly are positioned on the oval shape lens 1, whole formation lens 5.The whole lens of the present invention are made by age inhibiting high-purity clear glass.When the present invention is installed on the LED lamp, as shown in Figure 6, the base of oval shape lens 1 is close to the light-emitting area of the led chip in the lamp housing 3 and is installed, cover upper lamp shade 4 then.
Embodiment two:
Referring to Fig. 3 Fig. 5, present embodiment is to be provided with triangle bodily form lens 2 on oval shape lens 1.The middle part of oval shape lens 1 caves inward, oval shape lens base is a straight flange, triangle bodily form lens 2 are the isoceles triangle bodily form, the base of triangle bodily form lens 1 is positioned on the oval shape lens 1, two waists of triangle bodily form lens 1 are positioned at the depression position of oval shape lens 1, and triangle bodily form lens 2 uprightly are positioned on the oval shape lens 1.The middle part of oval shape lens 1 caves inward, and is more conducive to the expansion of hot spot and filters out veiling glare.
