Description
Technical field
The present invention relates to the optical module for motor-driven vehicle headlight adapter, the optical module includes transformation device and luminescent device, institute
Stating transformation device has the luminescent substance of arrangement on a carrier layer, wherein the luminescent substance has a large amount of transformation sections, described
Transformation section is formed by the deepening portion in the luminescent substance, wherein the luminescent device is set up to the excitation transformation
Section radiating light in a manner of Wavelength conversion.
Present invention is equally related to the motor-driven vehicle headlight adapters at least one optical module according to the present invention.
Background technique
Because such as laser light mechanism usually projects relevant, monochromatic light or the light in narrow wave-length coverage, but in machine
In the case where motor-car headlight, for the light of injection, white mixed light is preferred or legally defines white
Mixed light, be used to convert substantially monochromatic light so being disposed with so-called transformation device along the injection direction of laser light mechanism
At white or polychrome light, wherein " white light " is understood as that the light of following spectral composition, causes for people
The color impression (Farbeindruck) of " white ".The transformation device is for example with one or more luminescence generated by light converters or hair
The form of stimulative substance constructs, wherein the incident laser beam of laser light mechanism runs into converter usually with luminescent substance
On part and motivate the luminescent substance or photoluminescent color substance (Photolumineszenzfarbstoff) photic hair
Light, and light is released herein with the wavelength or wave-length coverage different from the light of the laser light mechanism of injection.The light of transformation device is put
Out herein substantially with the characteristic of Lambertian radiator.
The transformation device of the transformation device and transmission of reflection is distinguished for light transformation element.
The blue share of light of the concept of " reflection " and " transmission " herein based on converted white.In the structure of transmission
In the case of, the main direction of propagation of share of blue light is substantially penetrated with initial laser after penetrating converter volume or transformation device
The identical direction in the direction of propagation of beam.In the case where the structure of reflection, laser beam is on the boundary that can belong to transformation device
It reflects or turns at face, so that share of blue light has the biography different from the laser beam of laser beam that may generally be implemented as blue
Broadcast direction.
It is known from the state of the art mixing for example originating from yttrium-aluminium-garnet (Ce:YAG) for having garnet structure, such as doping cerium
The transition material or luminescent substance of the classification of miscellaneous compound, wherein diversified to be presented differently in terms of size
Particle combine matrix in form (konfektioniert), described matrix be fixed on it is with the high capacity of heat transmission, for example by
On the carrier that sapphire is constituted.In conversion, intensive, line focus laser beam is (such as example big in the motor vehicle for playing scan action
As used in lamp) in the case where, there is the heat management about converted luminous point and the resolution ratio that can reach
Or the limitation of contrast, because laser beam introduce, that preferably (fein) is focused passes through at the particle for playing transformation
Multiple scattering expanded.
It is same to influence also to occur in the case where no matrix, sintering ceramics transformation device, in the ceramics transformation
In device, each crystallite or tissue crystal grain work or hole is worked as scattering center usually as scattering center.
The state of all following partial volumes (Teilvolumina) of concept " tissue " characterization, from wherein each partial volume
It is fixed in terms of the arrangement spatially of its composition and its component part (Bausteine) about in merging raw material, position
Coordinate system is quite approximately uniform.
The tissue is characterized by the type of organizational component, form, size, distribution and orientation.
In addition, ceramics, such as Ce:YAG of multiphase construction can be used as scattering center together with the structure of hard rock and work.
However, it is not other for inhibiting the widened measure of lateral luminous point in the case where, grid cannot be used
Mould the system or motor-driven vehicle headlight adapter of (abbildenen).
It is for especially reducing the widened measure for having chance of success of lateral luminous point in the system of reflection from original
The compact basic ceramics that begin set out luminescent substance are pointedly divided into each section.
This section (being known as transformation section during below) generates by introduction into the deepening portion in luminescent substance.
However the shortcomings that this structuring, is, mechanical strength and overall integrity (such as by micro- in each section
Crackle fractures) it is weakened.
In addition, in the prior art, reliably for the use of laser, although the failure risk of each section improves, still
It is not provided with functional scheme for interior monitoring transformation device.
