Abstract
The utility model discloses an integrated large power LED (light-emitting diode) lens. On the one hand, the external surface of the lens is a free curved surface for light distribution, and the free curved surface takes on a peanut shell shape which is in bilateral symmetry; on the other hand, a concave semi-sphere is arranged at the center area of the other surface of the lens at the back of the external surface. The integrated large power LED lens has a simple structure and reasonable design, is convenient to realize and use and operate, has a wide application range, realizes a rectangular light shape with the proportion of 1 to 4 and uniform light distribution, has low cost, overcomes the defects in the prior art that the LED lamp has low light transmittance, the illumination distribution is not uniform and the like, has good use effect, and is convenient to popularize and use.
Description
Technical field
The utility model relates to a kind of LED lens, especially relates to a kind of integrated high-power LED lens.
Background technology
Be accompanied by improving constantly of China's urban construction fast development and living standards of the people, city illumination and room lighting cause also begin flourish, in recent years, the New Times of lighting engineering revolution has been opened up in the development of LED technology, because LED has the advantages such as volume is little, life-span length, electric light high efficiency, environmental protection and energy saving, so that the LED lighting engineering is obtaining rapidly development.Particularly because the road lighting area is large, luminous intensity is high, required luminous flux requires high, and the light uniformity of requirement is high.Therefore, the light-emitting area that in road lighting, needs vast scale.Therefore, in road lighting, need the light-emitting area of vast scale just particularly important.Be roughly in traditional method:
1. adopt the method for the power that increases light source, but this scheme can increase the consumption of the energy.
2. adopt the lamp distance that reduces between the street lamp, but this method increases cost, also less feasible;
3. increase the height of street lamp, but this is less feasible.
The utility model content
Technical problem to be solved in the utility model is for getting in the above-mentioned technology not enough, and a kind of novel integrated high-power LED lens is provided.
For solving the problems of the technologies described above, technical scheme of this applicable novel employing is: the outer surface of the utility model integrated high-power LED lens is for being used for the free form surface of luminous intensity distribution, and described free form surface is left and right symmetry shape take the matrix arc groove of centre as symmetrical centre; The central area with the opposing another side of outer surface of described lens is provided with the hemisphere face of indent.
The utility model compared with prior art has the following advantages:
(1) the utility model is simple in structure, and is reasonable in design, and it is convenient to realize, uses simple operation, applied widely, solved in the prior art in the LED light fixture that light transmittance is low, the unequal defective of illumination patterns and deficiency, and result of use is good, is convenient to promote the use of.
(2) in use, the LED lens are placed on directly over the integrated high-power light source, and consist of the LED module after fixing with pressing plate, then the LED module is placed on the flat board simply and can consists of whole lamp.This LED street lamp is fairly simple aspect frame for movement, heat radiation, power supply control, and the LED power that the road lighting of different brackets highway and different pole height only need to increase varying number gets final product, and uses simple operation, and is applied widely.
(3) the utility model spot light light type that high-power integrated packaging LED can be sent is made into the rectangular light type, realizes the luminous intensity distribution light type of 1:4, has realized that the rectangular light of 1:4 distributes.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the upward view of Fig. 1.
1-free form surface, the hemisphere face of 2-indent, 3-pressing plate step.
The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As depicted in figs. 1 and 2, on the one hand, the outer surface of the utility model lens is for being used for the free form surface 1 of luminous intensity distribution, and free form surface 1 is left and right symmetrical peanut shelly, and namely free form surface 1 is left and right symmetry shape with the matrix arc groove of centre.On the other hand, lens with the opposing another side of outer surface on, its central area is provided with the hemisphere face 2 of indent; In addition, be provided with pressing plate step 3 in the bottom of lens.
The utility model is placed on the LED lens directly over the light source in use, and consists of the LED module after fixing with pressing plate, then the LED module is placed on the flat board simply to consist of whole lamp.Just can realize very easily being installed on the requirement of replacing.This LED street lamp is fairly simple aspect frame for movement, heat radiation, power supply control, and the LED power that the road lighting of different brackets highway and different pole height only need to increase varying number gets final product.The light that led light source sends incides lens through the hemisphere face 2 of indent, and the luminous intensity distribution of process free form surface 1 is gone out divergence of beam again, thereby finishes the luminous intensity distribution to led light source.
During use, the hemisphere face 2 of the indent of the utility model lens coincides with the light-emitting area of the great power LED of multi-chip integration packaging.Because free form surface 1 is left and right symmetrical peanut shelly, and be provided with the hemisphere face 2 of indent in the central area of opposing another side, the hemisphere face 2 of the process indent of the light that led chip sends carries out scattering and refraction, carry out the scattering of secondary by free form surface 1 again, not only effectively realize the luminous intensity distribution of 1:4, also can realize the even distribution of light.
It below only is preferred embodiment of the present utility model; be not that the utility model is done any restriction; every any simple modification, change and equivalent structure of above embodiment being done according to the utility model technical spirit changes, and all still belongs in the protection domain of technical solutions of the utility model.
Claims (1)
1. integrated high-power LED lens is characterized in that: the outer surface of described lens is for being used for the free form surface (1) of luminous intensity distribution, and described free form surface (1) is left and right symmetry shape take the matrix arc groove of centre as symmetrical centre; The central area with the opposing another side of outer surface of described lens is provided with the hemisphere face (2) of indent.
