Description
Technical field
The utility model relates to the led light source lighting field, particularly a kind of LED collector lens.
Background technology
Illuminating lamp at the sight spot, park, the exhibition of interior decoration, guild hall all has indispensable effect, played the effect of playing up atmosphere, decorating view, beautify the environment.For satisfying lighting demand, people still adopt traditional illumination lamp, one of its topmost shortcoming is that power consumption is high, such as incandescent lamp, it is interior energy that its principle is based on electric energy conversion, next luminous by heating, its electric energy almost completely is converted into heat, cause luminance shortage, the life-span is short, and it also fails to reach the requirement of present low-carbon environment-friendly far away; And the traditional lighting light fixture need to produce colored light with optical filtering or optical filter, and not only efficient is low, photochromic mixes, and can not realize the color change of dynamic or gradual change, is difficult to satisfy different application needs.At present, country more and more payes attention to lighting energy saving and environmental issue, and the LED light fixture of being described as " green illumination " product by industry has energy-saving and environmental protection, long-life, controllability high-technology advantage, will the traditional light fixture of very fast replacement, now be badly in need of a kind of collector lens that can increase LED light fixture light extraction efficiency and strengthen LED light fixture projection brightness.
The utility model content
The technical problems to be solved in the utility model provides a kind of light extraction efficiency large for prior art, and projection brightness is strong, can project the LED collector lens of uniform light spots.
In order to realize above-mentioned technical problem, the utility model adopts following technical scheme:
A kind of LED collector lens, it is characterized in that: comprise cup, illuminator mounting groove, the plane of incidence, pearl face and assembling step, described cup is stage body, the upper bottom surface area of described cup is less than the bottom surface area, described cup upper bottom surface has the illuminator mounting groove, described illuminator mounting groove diapire is the described plane of incidence, and described cup lower end is described pearl face, and described cup edge is provided with the assembling step.
Preferably, the sidewall of cup for by camber line around a central shaft formed curved surface that rotates a circle.
Preferably, the plane of incidence is the convex surface with respect to cup upper bottom surface projection.
Preferably, pearl face surface is provided with cellular finish coat.
Preferably, the cup upper end is provided with ring-like projection.
The beneficial effects of the utility model: a kind of LED collector lens of the utility model, light throws from the plane of incidence, and the plane of incidence has spotlight effect to light, can increase light utilization efficiency and prolong irradiation distance; Be provided with ring-like projection in cup upper bottom surface upper end, to increase the lens degree of depth, so that ray cast is even, angle is concentrated; Cup for by camber line around a central shaft formed bench-type that rotates a circle, the inwall of cup is fully reflecting surface, sidelight all can be collected and reflected away, and increases light utilization efficiency, reduces the luminous energy loss; Exit facet is designed to the pearl face, and pearl has scattering process in the face of light, and light is through the pearl face
After can project evenly beautiful hot spot.Analysis-by-synthesis, a kind of LED collector lens of the utility model can increase light utilization efficiency, reduces the luminous energy loss, and throw light is concentrated, and brightness is large, and hot spot is evenly beautiful.
Description of drawings
Fig. 1 is the side sectional view of a kind of LED collector lens of the utility model;
Fig. 2 is the overall structure front schematic view of a kind of LED collector lens of the utility model;
Fig. 3 is the overall structure schematic rear view of a kind of LED collector lens of the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment, need to prove, and below only be detailed description to the utility model preferred embodiment, do not consist of any restriction of the present utility model.
One preferred embodiments of a kind of LED collector lens of the utility model comprises illuminator mounting groove 1, cup 2, the plane of incidence 3, pearl face 4, assembling step 5 and ring-like protruding 6.Cup 2 is stage body, the sidewall of cup 2 for by camber line around a central shaft formed curved surface that rotates a circle, the upper bottom surface area of cup 2 is less than the bottom surface area, the inwall of cup 2 forms the fully reflecting surface inwall, sidelight all can be collected and reflected away, increase light utilization efficiency, reduce the luminous energy loss.Upper bottom surface at cup 2 has illuminator mounting groove 1, and illuminator mounting groove 1 diapire is the plane of incidence 3, and preferably, the plane of incidence 3 is the convex surface with respect to cup 2 upper bottom surface projections; Convex surface has the optically focused effect to light, can increase light utilization efficiency and prolong irradiation distance.The lower end of cup 2 is pearl face 4, and preferably, pearl face 4 surfaces are provided with cellular finish coat, and 4 pairs of light of pearl face have scattering process, can project evenly beautiful hot spot behind the light process pearl face 4; In addition, 4 pairs of LED collector lenses of pearl face have decoration function.Be provided with assembling step 5 at cup 2 edges, make things convenient for LED collector lens and the assembling that carrier is installed.Preferably, also be provided with ring-like protruding 6 in the upper end of cup 2, ring-like protruding 6 interior diameter is greater than illuminator mounting groove 1 notch diameter, ring-like protruding 6 so that the distance increase between LED luminescence chip and the plane of incidence 3, LED luminescence chip crevice projection angle behind the plane of incidence 3 optically focused diminishes, so that ray cast is even, angle is concentrated, illuminator adopts the LED luminescence chip, have that energy consumption is low, volume is little, the advantage such as long service life, maintenance cost are low, and can by changing the LED modules with different colors luminescence chip, make the LED collector lens project the hot spot of respective color.
The above analysis gained, a kind of LED collector lens of the utility model is easy to assembly simple, can increase light utilization efficiency after the use, reduces the luminous energy loss, and has throw light and concentrate, and irradiation distance is long, and brightness is large, and hot spot is the advantage such as beauty evenly.During for illumination brightness requirement requirements at the higher level, can be designed to the LED collector lens module of a plurality of cups 2, make engineering design simpler.The specific embodiment of the present utility model is to adopt transparent material to make the combination concentration lens, and wherein, transparent material is plastic cement, PMMA etc.
The above describes in detail preferred embodiments of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; every various equivalences of doing in essential scope of the present utility model change or substitute, and all belong to the protection category of the utility model patent.
