The receiving portion of discrete piece.
Specifically, as illustrated, the tube-like envelope 11 is cuboid, therefore it has four side walls, then the leaded light
Piece 12 also has four, and one-to-one corresponding is fixed on the inner surface of each side wall, and the fixed form is preferably bonding mode, certainly
In other embodiments, also may be, for example, the modes such as engaging, screw lock, can all be changed according to the actual requirements;Wherein, have relative
End of a pair specific light guide sheets 12 (i.e. upper and lower two panels) at the light guide opening 14 position deeper into tube chamber, and other
The end position of light guide sheet 12 (left and right two panels) is more outward set, so as to form two grooves of longitudinal arrangement, for being embedded
The neighbouring position of the upper/lower terminal of the diffusion sheet 13 of rectangle as illustrated in figure 1 c, it is preferred that in the present embodiment, the groove
Width it is corresponding with the width of diffusion sheet 13, after diffusion sheet 13 is inserted, with the institute of diffusion sheet 13 planar to the expansion
Discrete piece 13 is positioned.
Also, the tube-like envelope 11 is provided with outside the exterior surface of the diffusion sheet 13 at the open end 111
Stop configurations, with least spacing diffusion sheet 13 in described accommodation section, specifically, as shown in Fig. 1 a and Fig. 1 d, Fig. 1 d
It is the structural representation of the front viewing angle of open end 14 of Fig. 1 a, the stop configurations include:At least one pair of first block piece 112, from
The a pair of sidewalls for being fixed with the specific light guide sheet 12 is extended to outside the outer surface of the diffusion sheet 13;In the present embodiment
In, the pair of first block piece 112 be from the upper and lower side wall of tube-like envelope 11 to the end face of open end in extend, so as to keep off
The outer surface of the diffusion sheet 13 (i.e. with its towards receiving portion one side opposite face) opposite sides so that diffusion sheet 13 is limited
It is fixed in described accommodation section, meanwhile, a pair first block pieces 112 also in specific light guide sheet from described open simultaneously by gear
Put on the route that end drops out.
Certainly, in other embodiments, the stop configurations can also be changed according to the actual requirements, it is only necessary to can spacing institute
Diffusion sheet is stated, is not limited with the present embodiment.
It is preferred that but it is nonessential, as shown in Fig. 1 a and 1d, in order to prevent other light guide sheets 12 may be from the open end
111 drop out, then from each side wall for being fixed with other light guide sheets 12 (being left and right two panels in the present embodiment) extend to it is each its
Multiple second block pieces 113 of the exterior surface (i.e. towards the surface of open end) of its end of light guide sheet 12, it is preferred that it is described other

In the above-described embodiments, it is the tube-like envelope with tube-like envelope integrally that each block piece 112 and 113 can be
The convex portion that side wall wall (preferably wall edge) is extended.
Embodiment 2:
As shown in Fig. 2 a to 2d, the guiding device 2 in this implementation is essentially consisted in the difference of a upper embodiment, the expansion
The setting direction (or its shape) of discrete piece 23 changes, and in embodiment 1, the diffusion sheet 13 of rectangle both sides wide are upper and lower
Position, both sides long are in left and right position, and in the present embodiment, and the both sides of the length of diffusion sheet 23 of rectangle are wide in upper and lower position
Both sides in left and right position, in order to realize conveniently, equally by light guide sheet (arranged on left and right sides) work of the both sides wide of diffusion sheet 23
For specific light guide sheet 22, its end depth is big compared with other light guide sheets 22 (upper and lower both sides), so as to be correspondingly formed groove, with chimeric
The position of the arranged on left and right sides of diffusion sheet 23, and the tube-like envelope 21 in the present embodiment can continue to use the tube-like envelope 11 of embodiment 1,
Need not re-mold, it is cost-effective;In the present embodiment, compared to embodiment 1, first block piece 212 in the present embodiment
Effect with the second block piece 213 is exchanged, and the first block piece 212 is for other light guide sheets 22 of block, and second block piece 213
For spacing diffusion sheet 23.
The structure of the above example guiding device of present patent application by way of example only, it is impossible to exhaustive all of knot
Structure, those skilled in the art should be changed according to the teaching of above-described embodiment, such as in other embodiments, described
Tube-like envelope is external except the multiaspect in previous embodiment, can also be cylindrical shape, then each light guide sheet can be that can surround cylinder
The arc of shape, and relative recessed in two positions can be formed with principle similar to the aforementioned embodiment in the cylindrical ends for surrounding
Groove, and be used to be fitted together to the diffusion sheet, in order that diffusion sheet is positioned, the diffusion sheet can be shape adjacent to the two ends of light guide sheet
The arc of shape matching, so as to complete to combine;And then diffusion sheet or gear are positioned by each block piece that tube-like envelope extends internally
Only light guide sheet is dropped out, and explanation is no longer launched one by one.
Need to further illustrate, present patent application is provided and may also provide projector equipment, preferably radium-shine projector equipment, bag
Described guiding device is included, the projector equipment may include:DLP projector etc., the photoconductive tube of the projector equipment front end passes through
The guiding device realization, because light path is shorter, is not lost the efficiency of blue light paths not only, can also simply adjust diffusion sheet
