Utility model content
In place of the deficiencies in the prior art, the mixed light condenser system that this utility model provides that a kind of energy of light source little, light efficiency utilization rate of loss is high, can realize beam angle scaled, colour mixture uniformly, simple in construction, light path reliability are high.
According to mixed light condenser system provided by the utility model, including: LED light source, light mixing lens and focusing lens；Described light mixing lens is arranged at the top of described LED light source along optical path direction, and described focusing lens is arranged at the top of described light mixing lens；Described light mixing lens includes that the first microlens array and the second microlens array, described first microlens array are planar array；Described second microlens array is spherical array；Described second microlens array is arranged at the top of described first microlens array.
Preferably, also include that substrate, described LED light source are installed on described substrate.
Preferably, described LED light source is the LED light source of several array arrangements.
Preferably, described first microlens array is made up of several hexagon lenticulees.
Preferably, the surface engraving of described first microlens array is textured.
Preferably, described second microlens array is made up of several difform lenticulees.
Preferably, the surface of described second microlens array is sprayed with optics fine sand.
Technical scheme provided by the utility model can include following beneficial effect:
(1) light mixing lens of this mixed light condenser system includes aspheric surface the first microlens array and sphere the second microlens array, aspheric surface the first microlens array is made up of hexagon lenticule, and the surface of the first microlens array is provided with special texture structure by laser engraving and injection molding process, this structure can carry out mixed light for the first time to incident monochrome or multi-color LED light source, and light mixing effect is uniform, effect is good.And sphere the second microlens array is made up of difformity lenticule, its surface is sprayed with optics fine sand.Second microlens array carries out second time mixed light to light.Through the light of secondary mixed light already close to white light light, effective, meet the demand of light stage.
(2) this mixed light condenser system can arrange multiple array LED light source or multiple mixed light condenser system array arrangements on substrate, and when the system of this spline structure of use, color blending effect will be more prominent.This mixed light condenser system colour mixture is uniform, light efficiency is high, focusing range is big, simple in construction, reliability are the highest.

Reference: 1, LED light source；2, light mixing lens；21, the first microlens array；22, the second microlens array；3, focusing lens.
Accompanying drawing herein is also listed description in and constitutes a part for description, it is shown that meets embodiment of the present utility model, and is used for explaining principle of the present utility model together with description.
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
As it is shown in figure 1, the mixed light condenser system provided by this utility model embodiment, including: LED light source 1, light mixing lens 2 and focusing lens 3.Light mixing lens 2 is arranged at the top of LED light source 1 along optical path direction, and focusing lens 3 is arranged at the top of light mixing lens 2.
As in figure 2 it is shown, be the structure chart of light mixing lens 2.Light mixing lens 2 includes the first microlens array 21 and the second microlens array 22, and the first microlens array 21 is aspheric surface array；Second microlens array 22 is spherical array；Second microlens array 22 is arranged at the top of the first microlens array 21.
Below, the structure of the first microlens array 21 and the second microlens array 22 is further described.First microlens array 21 could be arranged to planar array, can be made up of several hexagon lenticulees, and its surface can be carved with texture.First microlens array 21 can carry out mixed light for the first time to incident monochrome or polychrome light, and light mixing effect is uniform, and effect is good.Second microlens array 22 is made up of several difform lenticulees, and its surface is sprayed with optics fine sand.Second microlens array 22 carries out second time mixed light to light.Through the light of secondary mixed light already close to white light light, effective, meet the demand of light stage.
Below, the set-up mode of LED light source 1 is further described.This mixed light condenser system also includes that substrate, LED light source 1 are installed on described substrate.LED light source 1 can be the LED light source 1 of several array arrangements, and now color blending effect will be more prominent.
The operation principle of this utility model embodiment is as follows:
The optically focused light mixing system that this utility model embodiment is provided, including LED light source 1, light mixing lens 2 and focusing lens 3.The light that LED light source 1 sends first passes around the first microlens array 21 of light mixing lens 2, the special texture on the first microlens array 21 surface carries out mixed light for the first time to light, then the light after first time mixed light through this aspheric surface first microlens array 21 and reflects, and light ray energy is assembled and beam angle reduces；Subsequently, there is second time mixed light through the second microlens array 22 in light, now, light the most by evenly mixing and reaches the effect close to white light；White light is again through focusing lens 3, by distance before and after adjustment focusing lens, it is possible to realize spot size scaling.If LED light source 1 array arrangement in LED-baseplate, or multiple optical system uses simultaneously, and color blending effect will be more prominent.This optical system colour mixture is uniform, light efficiency is high, focusing range is big, simple in construction, reliability high.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and within all these changes and deformation all should belong to this utility model scope of the claims.
