Abstract
The utility model relates to a calculus light distribution lens for a light-emitting diode (LED) lighting lamp; the outer surface of the lens comprises at least one discontinuous reflection surface; and the discontinuous reflection surface comprises a plurality of reflective fins. The surfaces of the reflective fins are planes or curved planes. According to the utility model, the lens can overcome the phenomenon that as the colors of light emitted by an LED light source are different in all angles, the colors on a lighting field are inconsistent, and has the characteristic that the colors on a radiation area are uniform and consistent.
Description
Technical field
The utility model relates to the illuminating LED light fixture, particularly relates to can overcoming the light that sends because of led light source at the inconsistent lens that cause the inconsistent phenomenon of color on the illuminated field of its color on all angles.
Background technology
LED has been widely used in various lightings as the novel energy-conserving light source, like the PAR lamp of indoor use, the street lamp of outdoor application, Tunnel Lamp, advertising lamp etc.In order to improve the light extraction efficiency of led light source; Improve the light emitting sheet area of led chip as far as possible; Usually be employed in and carry out cutting on the LED luminescence chip; If adopting above-mentioned light source to cooperate existing reflecting surface is the lens of continuous face, the zone very easily produces the color non-uniform phenomenon showing up at the low-angle lighting field.
With reference to Fig. 1 and Fig. 2; For having the led light source that on the LED luminescence chip, carries out cutting now; Said led light source is the surface groove 111 that is encapsulated in the encapsulating material 230 and is placed on the led chip 110 on the substrate 220; The light that such light source sends spatially colour temperature has bigger difference, with reflective surface 310 as shown in Figure 3 for the conventional lenses of continuous face is used, be easy to generate the even phenomenon of irregular colour in the field of illumination.
The utility model content
The purpose of the utility model provides a kind of calculus light-distribution lens that the uniform LED lighting of color is used on the field of illumination.
This novel purpose is achieved in that the calculus light-distribution lens that a kind of LED lighting is used, and comprises lens, and the outer surface of said lens is made up of at least one discontinuous reflecting surface, and this discontinuous reflecting surface is made up of a plurality of reflective scales again.
The face shape of above-mentioned reflective scale is plane or curved surface.
The outer surface of said lens is designed to bowl-type.
The top of said lens is provided with the opening that led light source is installed.
Said lens is a plurality of, and a plurality of lens are injection-moulded in becomes the All-in-One overall lens together.
The calculus light-distribution lens that a kind of LED lighting luminous intensity distribution that this patent proposes is used, exactly to the light that sends spatially the colour temperature led light source that has a bigger difference use the technical scheme that has field of illumination color non-uniform phenomenon in the lighting and adopt.
The beneficial effect of the utility model is: this LED luminous intensity distribution comprises at least one discontinuous reflecting surface with the reflecting surface of lens; Its reflecting surface is made up of a plurality of scales that clocklike, have a reflective characteristic.Top open part at lens is placed led light source, and reflective scale carries out the shaping differential on demand to the received part light that is sent by LED, reflects superposition integral then to the zone that needs illumination.The part light that led light source sends reaches the field of illumination behind reflecting surface, reflecting surface is to be made up of a plurality of scales with reflective characteristic.Opening part is placed led light source above lens, and integration is carried out through a plurality of scale reflection differential in the corrugated of the part light that led light source sends in the field of illumination, and stack shines the zone that needs illumination; Lens with this characteristic can overcome the light that sends because of led light source in the inconsistent inconsistent phenomenon of color that causes on the illuminated field of its color on all angles.
Through changing face shape, quantity, spatial attitude and the arrangement mode etc. of reflective scale; Can realize the various angle distribution that the LED indoor illumination light fitting needs; As required 15 °, 20 °, 24 °, 30 °, 45 ° etc. usually, guarantee that simultaneously color is even in the field of illumination.

The specific embodiment
In order to make this patent technical problem to be solved, technical scheme and to have a mind to that effect is more clear to be understood,, this patent is further specified in conjunction with accompanying drawing and embodiment.Should be appreciated that instantiation described herein just to the explanation this patent, and be not used in the qualification this patent.
Please with reference to Fig. 4, be first embodiment that this patent provides, the calculus light-distribution lens that this LED lighting is used comprises lens, and the outer surface of lens is made up of at least one discontinuous reflecting surface 410, and this discontinuous reflecting surface is made up of a plurality of reflective scales 411 again.
The led light source that is placed on the lens openings place sends part light; Process plane of refraction 420 is refracted on the reflective scale 411 on the reflecting surface and reflects differential; Be mapped on the illuminated area through exit facet 430 again, like this through the equal superposition integral of many groups light beam of a plurality of scales reflection to illuminated area.The quantity of reflective scale, discharge capacity mode, face shape and spatial attitude mainly are the light beam shooting angle decisions by the uniformity of the Energy distribution on the illuminated area, energy distribution uniformity, color distribution, light fixture; Certainly the light that when design, will as far as possible consider to be mapped on the reflective scale can be accomplished total reflection in material, can certainly on reflective scale, plate the reflection that reflective membrane is accomplished light.The face shape of reflective scale is plane or curved surface.The outer surface of lens is designed to bowl-type.The top of lens is provided with the opening (opening that led light source is installed is arranged on the small end of bowl-type lens, on the big end exit facet is arranged) that led light source is installed.
Like this, each reflective scale 411 reflects the part light that led light source sends, and mixing is added to needs will form the illuminating effect of even transition on the face of illumination.
, be this patent first embodiment and led light source assembling sketch map please in actual use with reference to Fig. 6.
Led light source 620 is placed on the small end opening part of lens 610.Can be combined into the LED lighting of different capacity through such combination.
Lens are a plurality of, and a plurality of lens are injection-moulded in becomes the All-in-One overall lens together.
Fig. 7 is second embodiment of this patent; Combine integral molded plastic by five the first given calculus lens 710 of embodiment; Be combined into the whole calculus lens of five in one, wherein 720 is reference column, can form All-in-One calculus lens arbitrarily according to the thinking of second embodiment.
