Abstract
The utility model discloses a multifunctional optical module which is arranged in front of a light source, is provided with a substrate and at least two optical elements arrayed on the substrate; eachoptical element comprises a raster non-spherical surface lens array and a non-spherical surface lens respectively in front and back sides, the raster non-spherical surface lens array is arranged close to the light source and the non-spherical surface lens is arranged far from the light source. When the multifunctional optical module is adopted, the utilization rate of optical energy is improved and the energy saving effect is realized; meanwhile, the multifunctional optical module can form even light spots for different lighting areas according to the demands of the lighting areas.
Description
Technical field
The utility model relates to lighting technical field, in particular for the optical module of illumination.
Background technology
Existing illuminating lamp, light be to around disperse, the utilization rate of its luminous energy is scarcely high.In existing lighting engineering, improve for pursuing the utilization rate of luminous energy so that therefore energy savings has just had optical module, by optical module draw in, collected light.
Some field of illumination also needs special light spot shape, as: rectangle, circle, ellipse etc.But existing lighting engineering can't make the shape of hot spot adapt to specific field of illumination.
The utility model content
Technical problem to be solved in the utility model provides a kind of multifunctional optical module, and it can improve the efficiency of light energy utilization of light source, and can produce special illumination hot spot.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of multifunctional optical module, be used to be arranged on light source the place ahead, has substrate, on substrate, be disposed with at least two optical elements, the raster-like non-spherical lens array and the non-spherical lens that are provided with before and after this optical element comprises, raster-like non-spherical lens array are arranged on the position near light source, and non-spherical lens is arranged on the position away from light source.
Raster-like non-spherical lens array is a raster-like semicylinder strip lens array.Raster-like semicylinder strip lens array has a side of semicolumn cambered surface towards non-spherical lens.
Optical element can rotate on substrate around its axle center.
Raster-like non-spherical lens array is parallel to the plane of substrate.
The utility model designs by the principle of " secondary optical system ", and this optical system can be made change to the light emission direction of light source.The skew of the direction of propagation can take place in light on the interface of different refractivity through different propagation medium the time, the direction of skew with incident angle and the refractive index of propagation medium of process relevant.
In the utility model, when light is injected from raster-like non-spherical lens array one side of optical element, when non-spherical lens one side penetrates, can form the hot spot of rectangle.Light changes behind raster-like non-spherical lens array, can on the direction of vertical raster hot spot be widened, and on the direction of parallel grating hot spot be restrained, thereby obtain rectangular light spot.When incident light passes through non-spherical lens again, can remove unnecessary veiling glare, can obtain the outgoing hot spot of uniform rectangle by the aberration of non-spherical lens correction light path.Because this rectangular light spot draws light, assemble in, has therefore just improved light intensity, has also promptly improved the utilization rate of luminous energy.A plurality of optical elements are carried out assembled arrangement on substrate, form optical module, adjust the anglec of rotation of each optical element, the synthetic difform irradiation hot spot of light spot group that each optical element can be penetrated.

The specific embodiment
As shown in Figure 1, 2, multifunctional optical module has a transparent substrate 1, be arranged on the place ahead of light source 3, on substrate 1, be disposed with optical element 2, this optical element 2 can be embedded on the substrate 1, the raster-like non-spherical lens array 5 and the non-spherical lens 4 that are provided with before and after this optical element 2 comprises, raster-like non-spherical lens array 5 are arranged on the position near light source 3, and non-spherical lens 4 is arranged on the position away from light source 3.Raster-like non-spherical lens array 5 is parallel to the plane of substrate 1.
As shown in Figure 3, raster-like non-spherical lens array 5 is a raster-like semicylinder strip lens array, and raster-like semicylinder strip lens array has a side of semicolumn cambered surface towards non-spherical lens.
In the present embodiment, the direction of the raster-like non-spherical lens array on the optical element on the substrate is all consistent, and the hot spot that its forms is a rectangle.Change the quantity of optics element row, row on the substrate, can change the size of rectangular light spot.
Adjust the distance of optical module and light source, also can exert an influence the power of intensity of illumination and the size of light spot shape.
As shown in Figure 4, the structure of present embodiment and embodiment 1 is basic identical, the quantity that only is optical element is different with the angle of each raster-like non-spherical lens array, the direction of the raster-like non-spherical lens array in the adjacent optical element is vertical mutually, and the light spot shape that it forms is a square.
As shown in Figure 5, the structure of present embodiment and embodiment 1 is basic identical, the quantity that only is optical element is different with the angle of each raster-like non-spherical lens array, the raster-like non-spherical lens array that is distributed in the optical element at four angles rotates a certain angle, and the light spot shape that its forms will be an ellipse.
Embodiment 4
Present embodiment is identical with the structure of embodiment 1, only be that each raster-like non-spherical lens array is different with the distance of light source, the direction of the raster-like non-spherical lens array in the optical element of adjacent column is can embodiment 1,2,3 identical, and its last light spot shape that forms will be a changeable shape.
2 above optical elements can be set on the substrate of the utility model multifunctional optical module, and can be by the shape and the size requirements of hot spot, arrange optical element, the size of multifunctional optical module, can decide according to the hot spot effect design of instructions for use, the shape of multifunctional optical module also can be circle, side, length, heart type, polygon, ellipse, and its form mainly requires to change according to the external form of light fixture; The substrate of multifunctional optical module can be transparent, also can be opaque, adopt not yielding, the uvioresistant width of cloth is penetrated, be difficult for aging material makes; Optical element position each other is adjustable, variable; Substrate and optical element can fuse by being difficult for aging adhesive, and its waterproof and dustproof of bonding back can reach the requirement of IP65.
Multifunctional optical module can make up with all kinds of spot lights, line source, area source, strengthens the illuminance effect; Can be used in combination with the LED lamp, the chip center of each LED is corresponding one by one with the center of each optical element.
