Abstract
The invention discloses a method for designing a micro projection illumination system by use of an energy viewpoint. The specific method comprises the following steps: a, during an LED condenser design process, attention should be given to the light beams to ensure the light beams are not cut off, and the parallelism of the light beams should be high; b, since the photoelectric conversion efficiency of a light source has a great effect on the brightness of a system, reasonable requirements should be brought forward for light source parts; c, the requirement for spectrum transmittance should be brought forward for all optical parts to be used in an illumination system; d, the energy ratio of three primary colors is controlled so as to ensure that no color cast exists in system light distribution; e, the brightness of the whole system at a projection screen should be evaluated, the integrated calculating of the energy utilization rate of various assemblies should be carried out, the calculating is a reference for inspecting whether the parts of the system accord with the requirements; and f, under the condition of maximum energy utilization rate of the illumination system, the optical axes of the optical assemblies must be aligned, therefore, there must be a method to ensure the requirement for alignment of the optical axes in a simulation process, and this is a principle for assembly arrangement.
Description
Technical field

Background technology
The key of micro-projecting illumination system is dimensional problem, can cause the cutting of illuminating bundle, therefore to each optics design, must assess with energy viewpoint, the highest to guarantee the utilization factor of luminous energy, to determine the permissible value of the limit that each part dimension reduces, the design of the each parts of illuminator be unable to do without the calculating of energy like this.
Summary of the invention
What the object of the present invention is to provide a kind of assessment method for designing take energy as important reference index carries out the method for designing of micro-projecting illumination system with energy viewpoint.Its concrete grammar is:
In the process of a, LED condenser design, to notice at any time that light beam is not blocked and cut, and it is high that the depth of parallelism of light beam outgoing is wanted, this is not blocked and is cut by projection lens smoothly for light beam, thereby the depth of parallelism to outgoing beam claims, in many designs of projection part, be all from the angle of raising capacity usage ratio, to go out to send to design;
The conversion efficiency of the photoelectricity of b, light source is very large on the brightness impact of system, therefore tackle light source part and propose rational requirement, therefore to provide the technical requirement of electric property, it is the brightness requirement after opto-electronic conversion, the foundation detecting using the circuit design as these parts and spectral energy utilization factor, with determine this part design with debug whether qualified;
C, the optics that will will use all illuminators propose the requirement of spectral transmittance, and whether to determine the design of corresponding component and debug qualifiedly in TracePro software simulation process, this is also to carry out illumination system layout from energy viewpoint;
The control of d, three primary colours energy Ratios, has used the COMPREHENSIVE CALCULATING of sorts of systems capacity usage ratio, to determine the ratio that whether meets white light through the three primary colours energy of system each several part in the synthetic ratio of projection in zone, to guarantee not colour cast of system luminous intensity distribution;
E, will assess the brightness of total system at projection screen place, have the COMPREHENSIVE CALCULATING of the capacity usage ratio of various components, it is the whether satisfactory basiss of reference of the each parts of check system;
F, at illuminator energy, utilize under maximal condition, the optical axis of each optical module must align, and therefore in simulation process, should have way to guarantee the requirement that optical axis aligns, and this is the principle of carrying out assembly layout;
After g, whole system layout are complete, also should provide the distribution of actual light, carry out structural design with this layout, during design, do not allow the trim ring bore in structure just to touch the ultimate limit state in light beam interception, the utilization factor that had so both guaranteed luminous energy has also guaranteed system requirement to parasitic light to projection image, guarantees that system has enough contrasts.
From technical scheme of the present invention, can find out, the design evaluation standard of all opticses and other base parts is all with efficiency of light energy utilization most significant digit standard, in other words the illumination section in micro-projection designed with energy viewpoint in when design, thus with the method for designing that energy viewpoint carries out micro-projecting illumination system be feasible.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
In the process of a, LED condenser design, to notice at any time that light beam is not blocked and cut, and it is high that the depth of parallelism of light beam outgoing is wanted, this is not blocked and is cut by projection lens smoothly for light beam, thereby the depth of parallelism to outgoing beam claims, in many designs of projection part, be all from the angle of raising capacity usage ratio, to go out to send to design;
The conversion efficiency of the photoelectricity of b, light source is very large on the brightness impact of system, therefore tackle light source part and propose rational requirement, therefore to provide the technical requirement of electric property, it is the brightness requirement after opto-electronic conversion, the foundation detecting using the circuit design as these parts and spectral energy utilization factor, with determine this part design with debug whether qualified;
C, the optics that will will use all illuminators propose the requirement of spectral transmittance, and whether to determine the design of corresponding component and debug qualifiedly in TracePro software simulation process, this is also to carry out illumination system layout from energy viewpoint;
The control of d, three primary colours energy Ratios, has used the COMPREHENSIVE CALCULATING of sorts of systems capacity usage ratio, to determine the ratio that whether meets white light through the three primary colours energy of system each several part in the synthetic ratio of projection in zone, to guarantee not colour cast of system luminous intensity distribution;
E, will assess the brightness of total system at projection screen place, have the COMPREHENSIVE CALCULATING of the capacity usage ratio of various components, it is the whether satisfactory basiss of reference of the each parts of check system;
F, at illuminator energy, utilize under maximal condition, the optical axis of each optical module must align, and therefore in simulation process, should have way to guarantee the requirement that optical axis aligns, and this is the principle of carrying out assembly layout;
After g, whole system layout are complete, also should provide the distribution of actual light, carry out structural design with this layout, during design, do not allow the trim ring bore in structure just to touch the ultimate limit state in light beam interception, the utilization factor that had so both guaranteed luminous energy has also guaranteed system requirement to parasitic light to projection image, guarantees that system has enough contrasts.
