From, and the conversion light is directed on conversion light path；Optical convergence's device, optical convergence's device are designed for meeting
The poly- reflected light from reflected light path and the conversion light from conversion light path.
Especially advantageous design scheme illustrates in embodiment and describes in the following description.
Laser as the preferred blue light of exciting light (light i.e. in blue spectral range), especially blue because in addition to
Except excitation light-emitting material, exciting light additionally be can also act as the color channel (blue reflected light) of blue.
Now, the basic thought of the utility model is: Wavelength converter is designed to so that not only to exciting light into
Row wavelength convert (hereinafter be also referred to as conversion light), and additionally and targetedly by exciting light at least temporarily and extremely
Partially unconvertedly, i.e. spectrum unchangeably reflects and (is hereinafter also referred to as reflected light).In this regard, Wavelength converter
With at least one reflecting element, it is spatially separated to divert the reflected light toward with exciting light path and conversion light path
On reflected light path.Be spatially separated by the way that light path and reflected light path will be converted, can reflected light and conversion light again
Before secondary convergence, the beam specification of reflected light and conversion light is individually influenced.
Conversion light and being spatially separating for reflected light are accomplished in that reflected light passes through change according to the utility model
Exciting light path, i.e. separate exciting light path the position of reflection at of the direction far from part, and in order to further utilize
And it deflects on reflected light path.
The degree that direction changes is the light in the part of the optical axial L1 and reflected light path of the part in exciting light path
Learn the variation angle α 3 between axis L2.With " local " optical axial indicate: relevant light path with Wavelength changing element or
The corresponding optical axial of the point of intersection on the surface of reflecting element.
Direction, which changes, is for example accomplished in that Wavelength changing element, such as luminous material layer and reflecting element, example
If mirror surface is formed on rotatable ontology, so that the institute of the optical axial L1 of the part in exciting light path and Wavelength changing element
The face normal N 1 of category forms angle [alpha] 1, and the angle is with the local optical axial L1's and reflecting element in the exciting light path
Angle [alpha] 2 between affiliated face normal N 2 is different.In other words, the surface of Wavelength changing element and the surface of reflecting element are not set
