Existing light emitting diode (LED, Light Emitting Diode) lamps and lanterns, have that light is mixed and disorderly out, colour mixture is uneven, by
This causes apparent light and shade area, and impinging upon has the problems such as color lump on wall.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of light mixing device, by improving lamps and lanterns
Optical path processing mode, solution decided the problem that light is mixed and disorderly, colour mixture is uneven, improved the photochromic quality of lamps and lanterns.
Based on this, the utility model proposes a kind of light mixing devices, including optically focused reflector, abrasive segments, Fresnel Lenses
With several lamp beads, the optically focused reflector is in a circular table shape, and the optically focused reflector has a first end and a second end, the rotary table
The end face of the optically focused reflector upper bottom surface side of shape is the first end, the round table-like optically focused reflector bottom surface side
End face is second end, and the lamp bead is installed on the first end of the optically focused reflector, and the Fresnel Lenses is installed on described poly-
The second end of light reflector is equipped with abrasive segments between the Fresnel Lenses and the optically focused reflector.
Optionally, the lamp bead is installed in lamp bead plate.
Optionally, the lamp bead is in octagon array arrangement.
Optionally, the lamp bead is the lamp bead of five kinds of colors.
Optionally, the quantity of the lamp bead is 37.
Optionally, the focal length of the Fresnel Lenses is 100-200mm.
Optionally, the abrasive segments are tightly attached to the Fresnel Lenses.
A kind of light mixing device of the utility model, including optically focused reflector, abrasive segments, Fresnel Lenses and several lamps
Pearl collects light by setting optically focused reflector, using abrasive segments uniform light, finally by Fresnel Lenses optically focused again,
Make light-emitting surface uniformly, light efficiency improve, thus solution has decided the problem that light is mixed and disorderly, colour mixture is uneven, improves the photochromic quality of lamps and lanterns.

It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
In addition, in the description of the present invention, unless otherwise indicated, the meaning of " plurality " is two or more.
For the ordinary skill in the art, it can understand above-mentioned term in the present invention with concrete condition
Concrete meaning.
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Fig. 1 is please referred to, the present embodiment provides a kind of light mixing devices, including optically focused reflector 1, abrasive segments 2, Fresnel Lenses
3 and several lamp beads 41, optically focused reflector 1 is in a circular table shape, and optically focused reflector 1 has a first end and a second end, and round table-like is poly-
The end face of 1 upper bottom surface side of light reflector is first end, and the end face of round table-like 1 bottom surface side of optically focused reflector is second
End, lamp bead 41 are installed on the first end of optically focused reflector 1, and Fresnel Lenses 3 is installed on the second end of optically focused reflector 1, Fei Nie
Abrasive segments 2 are equipped between that lens 3 and optically focused reflector 1.When lamp bead 41 works, the light that lamp bead 41 issues is in optically focused reflector
It is reflected on 1 inner wall, the angle of divergence of light can be reduced, and realize the effect of optically focused.Lamp bead 41 is mounted on optically focused reflector 1
First end, it is ensured that lamp bead 41 issue light can all be reflected onto Fresnel Lenses 3.Fresnel Lenses 3 is to optically focused
The light that reflector 1 is collected carries out optically focused again, can make light-emitting surface uniformly, light efficiency improves.Fresnel Lenses 3 is reflexed in light
Before, light will pass through the abrasive segments 2 being set between Fresnel Lenses 3 and optically focused reflector 1.In the present embodiment, frosted
Piece 2 is tightly attached to Fresnel Lenses 3.Since light can be imaged by Fresnel Lenses 3, abrasive segments 2 can allow divergence of beam to
Keep light more uniform, solution has decided the problem that light is mixed and disorderly, colour mixture is uneven, improves the photochromic quality of lamps and lanterns.
