A variety of coloured light of formula outgoing.Thereafter, coloured light is by optical channel 3, so as to be homogenized, via be provided with multiple speculums 5 with
And collector lens 4, incide TIR prism 6.The coloured light for inciding TIR prism 6 is emitted to image formation element 7 and turns into image
Light, TIR prism 6 is again incident on, is projected by projecting lens 8.
Fig. 2 (a), Fig. 2 (b) are the solids of the composition for an embodiment for showing lens holding structure of the present utility model
Figure and sectional view.
Holding structure shown in Fig. 2 keeps collector lens 9, by for keeping the base 10 of collector lens 9 and for solid
Surely the fixed component 11 that the collector lens 9 of base 10 is installed on using screw is formed.
Collector lens 9 is that the side of exit facet 12 is made up of flat shape, the side of the plane of incidence 13 is by sphere or aspherical shape structure
Into lens, be fixed to base 10.
Fig. 3 (a), Fig. 3 (b) are the stereograms for the structure for showing base 10.
The slot structure 14 of the position of the side of exit facet 12 for determining collector lens 9 is provided with base 10 and to optically focused
The lens abutting arrangement 15 that the side of the plane of incidence 13 of lens 9 is kept.
As shown in Fig. 2 (b), slot structure 14 engages the bottom of the side of exit facet 12 of the flat shape of collector lens 9.Thoroughly
Mirror abutting arrangement 15 is arranged at the top of slot structure 14, in order to by two of the lower portion of the side of the plane of incidence 13 of collector lens 9
Position engages and is provided with 2.The side of the plane of incidence 13 of collector lens 9 is sphere or aspherical shape, therefore lens abut knot
Structure 15 possesses step shape corresponding with the shape of the plane of incidence 13.In addition, the step shape can also be set to curve form.
Fig. 4 (a)~Fig. 4 (c) is the stereogram for the structure for showing fixed component 11.
Fixed component 11 is installed on base 10 in a manner of positioned at the top of collector lens 9 for being held in base 10, by with
Collector lens 9 directly connect and for kept spring shape 16 (the 1st spring shape), 17A (the 2nd spring shape),
17B (the 3rd spring shape), for preventing the claw shape 18 to come off of collector lens 9 and the reinforcement structure 19 of fixed component 11
Form.
Spring shape 16 is set from the side of exit facet 12 of collector lens 9 towards the side of the plane of incidence 13, and its end is bent over and done
Into claw shape 18.Spring shape 16 possesses suppresses collector lens 9 upper by pressing the upper end of the exit facet 12 of collector lens 9
Lower section moves up and collector lens 9 is pressed into the function of the lens abutting arrangement 15 of the side of the plane of incidence 13.It is expected to use spring
The upper end of collector lens 9 is pushed down at the center of shape 16.
Spring the shape 17A and 17B set towards slot structure 14 is configured to press the side of exit facet 12 of collector lens 9
Upper side end two positions, possess the function of the lens abutting arrangement 15 that collector lens 9 is pressed into the side of the plane of incidence 13.Separately
Outside, it can prevent collector lens 9 from swinging to the side of exit facet 12 due to impact etc..Spring shape 17A and 17B are directed to collector lens
9 and to push down end be in order to be pressed into the lens abutting arrangement 15 of the side of the plane of incidence 13 with not covering effective sunlight, but if can
The size not limited to this of enough distance, then spring shape 17A and 17B is kept relative to effective sunlight.
In addition, in spring shape 17A and 17B or wherein some plane of incidence for being mistakenly assembled into collector lens 9
In the case of 13 sides, because fixed component 11 can not be installed to base 10, therefore it can also detect in fixed component 11 and base
The assembling being likely to occur between 10, between base 10 and collector lens 9 is abnormal.
Claw shape 18 is set from the front end of spring shape 16 towards the direction of collector lens 9, not connect with collector lens 9
Mode adjust length.In the present embodiment, it is set to block fixed part from the external diameter end of the side of the plane of incidence 13 of collector lens 9
Length as the thickness+α of part 11 amount, but as long as being for avoiding the measure with other component interferences and not covering effective light
The length of line.
Reinforcement structure 19 by the end edge bending of the side opposite with the part for forming spring shape 16 by ensuring intensity.
On by bending come the reinforcement implemented, usually 90 ° bendings, but in the present embodiment, in order to avoid being done with other components
Relate to, be set to 180 ° of bendings.On the width of bending, centered on the summit of collector lens 9, be contemplated to be end face more than half
Length, the longer the better.
By setting these shapes, collector lens 9 can be persistently held in correct position.
