The optical module comprises an LED light source, a reflector and a light distributing lens, wherein the reflector is positioned above the LED light source; and the light distributing lens is installed above the reflector. The optical module of the LED lamp provided by the utility model can treat light rays emitted from the LED light source in a full-angle range and has the advantages that the light type view angle effect is good, the light-emitting efficiency is high, the weight is light, and the volume is small.
Description
Technical field
The utility model belongs to field of illuminating lamps, relates in particular to a kind of LED light fixture optics module.
Background technology
Existing LED light fixture adopts reflector or lens to carry out the light shaping usually; For the LED light fixture that adopts reflector to carry out the light shaping; Because reflector can only carry out shaping to the LED high angle scattered light, can not carry out shaping to LED low-angle light, causes the light shaping effect bad; For the LED light fixture that adopts lens to carry out the light shaping, because lens can not be too thin, thin lens light extraction efficiency is low, and lens are too thick can to cause consumptive material, volume, weight big again, is difficult for problems such as installation.
The utility model content
The purpose of the utility model provides a kind of LED light fixture optics module, can carry out the full angle scope to the light that the light fixture led light source sends and handle, and reaches the effect that light type view effect is good, light extraction efficiency is high.
For achieving the above object, the utility model is to adopt following technical scheme to realize:
The utility model provides a kind of LED light fixture optics module, comprises led light source, reflection shield, light-distribution lens; Said reflection shield is positioned at the led light source top, and said light-distribution lens is installed in the top of reflection shield.
Said light-distribution lens can be following thrin: the surface is the Fresnel lens of pearl face for Fresnel lens, the surface of light face or erosion line face for the Fresnel lens of cornice plane, surface.
The central area of said light-distribution lens is the Fresnel face, and the Fresnel face can also can also can exist at the inner surface and the outer surface of lens at the inner surface of lens in lens outer surface simultaneously.
Said light-distribution lens inner surface also can be made up of the annular prism.
Preferably, said reflection shield adopts high reflective white plastic material, but single injection-molded is processed.
The operation principle of the LED light fixture optics module that the utility model provides is following: the light that led light source sends sends through the light-distribution lens integer, the refraction that place the place ahead, and illumination is provided; Part reflexes to light-distribution lens again, penetrates through after the secondary reshaping, in order to illumination to be provided through the reflection shield that is installed in the light-distribution lens below through the light without shaping of said light-distribution lens reflection.
The advantage of the utility model is:
The LED light fixture optics module that the utility model provides, the light that adopts reflection shield and light-distribution lens that led light source is sent carry out multiple luminous intensity distribution, shaping is handled, and light type view effect is good, light extraction efficiency is high; Adopt Fresnel lens as light-distribution lens, can make light fixture do thinlyyer, thus the volume and weight of economical with materials, minimizing light fixture; Better, reflection shield adopts high reflective white plastic material, but single injection-molded is processed the reduction manufacturing cost.

Among the figure: 1-LED light source, 2-reflection shield, 3-light-distribution lens, 4-core light, 5-reflecting surface reflection ray, 6-surface are that Fresnel lens, the 7-surface of light face or erosion line face shape is the Fresnel lens of pearl face shape, 9-light-distribution lens central area outer surface, 10-light-distribution lens central area inner surface, 11-annular prism for the Fresnel lens of cornice plane shape, 8-surface.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing.
Like Fig. 1, the LED light fixture optics module that the utility model provides comprises led light source 1, reflection shield 2, light-distribution lens 3; Reflection shield 2 is installed in led light source 1 top, and light-distribution lens 3 is installed in the top of reflection shield 2; The light that led light source 1 sends is handled the back and is penetrated through luminous intensity distribution, the shaping of reflection shield 2 and light-distribution lens 3, and illumination uniformity is good, light extraction efficiency is high, light type view effect is good.
Like Fig. 3,4, embodiment 1, and light-distribution lens 3 is surface Fresnel lenses 6 for light face or erosion line face.
Like Fig. 5,6, embodiment 2, and light-distribution lens 3 is that the surface is the Fresnel lens 7 of cornice plane.
Like Fig. 7,8, embodiment 3, and light-distribution lens 3 is that the surface is the Fresnel lens 8 of pearl face face.
Like Fig. 9,10, embodiment 4, and the central area inner surface 10 and the outer surface 9 of light-distribution lens 3 are the Fresnel face, and non-central zone is an annular prism 11.
Like Fig. 2, prior art LED light fixture optics module does not have light-distribution lens 3, and the light core that led light source sends directly penetrates; Core light 4 can't obtain luminous intensity distribution and handle; Reflecting surface reflection ray 5 dispersion angles are big, and the projection light type is bad, and the irradiation of light is inhomogeneous.
Comparison diagram 1 and Fig. 2; Rising angle, the illumination uniformity that can reflect the LED light fixture optics module that the utility model provides obviously are better than prior art high-power LED lamp optics module; The LED light fixture optics module that the utility model provides can carry out the full angle scope to the light that the light fixture led light source sends to be handled, and light type view effect is good, light extraction efficiency is high, illumination uniformity good.Better, reflection shield adopts high reflective white plastic material, but single injection-molded is processed.
Certainly; The utility model also can have other various embodiments; Under the situation of spirit that does not break away from the utility model and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
