Based on above-mentioned, by lens arrangement 100 of the present invention, the light that light source 200 projects, just can be led to umbrella body 130 from pedestal 110, and and then each optical surface S2 (the second curved surface), S3 (the 3rd curved surface) from the umbrella body 130, P1 (the first inclined-plane) project this lens arrangement 100 with P2 (the first inclined-plane).Accordingly, lens arrangement 100 of the present invention just can produce visual range greater than the light effect that goes out of 180 degree.
Present embodiment does not limit the angle T1 between the first inclined-plane P1 and the second inclined-plane P2, in another unillustrated embodiment of the present invention, angle T1 also can be 180 degree, that is, the first inclined-plane P1 and the second inclined-plane P2 are copline, can make equally lens arrangement 100 reach visual range greater than the light effect that goes out of 180 degree.
Fig. 4 is the opticpath of light source in the lens arrangement of Figure 1A, at this only with the representative opticpath of part as an illustration.For the opticpath that makes Fig. 4 is clearly illustrated, Fig. 5 to Fig. 7 is respectively the part opticpath of Fig. 4.Please also refer to Fig. 3 to Fig. 7, in the present embodiment, storage tank 112 is the part of a spheroid, and light source 200 is positioned on the central shaft C1.
Moreover first surface S1 is a fully reflecting surface, and it is in order to will be from the light reflection of light source 200 to umbrella body 130, such as light L2 and the L3 that illustrates among the light L1 that illustrates among Fig. 5 and Fig. 6.Allly be projected to the light of first surface S1 from storage tank 112, it all can be reflected by first surface S1, and advances towards umbrella body 130.This measure allows the cylinder 120 of lens arrangement 100 have the function that light is collected to umbrella body 130.
In the present embodiment, on the projection plane P4 take central shaft C1 as normal, the second curved surface S2 the orthographic projection on this projection plane P4 by the orthographic projection institute of the 3rd curved surface S3 on this projection plane P4 around.In other words, on the umbrella body 130 of lens arrangement 100, the second curved surface S2 be essentially the 3rd curved surface S3 institute around.
Light that it should be noted that in addition Journalistic to the second curved surface S2 can penetrate the second curved surface S2, such as the light L1 among Fig. 5 and the light L2 among Fig. 6.At the same time, the light that another part is projected to the second curved surface S2 then can be reflexed to by the second curved surface S2 the lateral margin of umbrella body 130, such as the light L2 among Fig. 6 and light L5, L7 and the L8 among Fig. 7, wherein light L2 penetrates the second curved surface S2 that is projected to opposite side behind the second curved surface S2 of a side, is projected to the lateral margin of umbrella body 130 again.
Moreover the light of Journalistic to the second curved surface S2 then can be projected to first the lateral margin that reflexes to again umbrella body 130 behind the 3rd curved surface S3, such as light L6 and the L9 among Fig. 7.
Similarly, the light of Journalistic to the three curved surface S3 can penetrate the 3rd curved surface S3, such as the light L4 among Fig. 5.The light that another part is projected to the 3rd curved surface S3 then can be reflexed to by the 3rd curved surface S3 the lateral margin of umbrella body 130, such as the light L3 among Fig. 6 and light L6 and the L9 among Fig. 7.
Accordingly, the second curved surface S2 and the 3rd curved surface S3 in the present embodiment have the function that makes light penetration and reflection simultaneously, not only can allow part light project lens arrangement 100 from the top of umbrella body 130, also simultaneously another part light is directed to the lateral margin of umbrella body 130.In the present embodiment, the second curved surface S2 is a convex surface, and the 3rd curved surface S3 is a concave surface.Present embodiment is not limited this.In another unillustrated embodiment of the present invention, the 3rd curved surface can be a convex surface, and the designer can change accordingly according to the light that projects from storage tank 112 and cylinder 120.
Refer again to Fig. 3 and Fig. 4, at the lateral margin place of umbrella body 130, the first inclined-plane P1 is adjacent to the 3rd curved surface S3, and the second inclined-plane P2 is between the first inclined-plane P1 and first surface S1, and has angle T1 between the first inclined-plane P1 and the second inclined-plane P2.This measure allows the first inclined-plane P1 and the second inclined-plane P2 be able to the light from the second curved surface S2 and the 3rd curved surface S3 is projected equably the lateral margin of lens arrangement 100.Fig. 8 is the Illumination Distribution figure that the light source of Fig. 4 produces via lens arrangement, and wherein that the representative of the unit of radial coordinate is luminous intensity (Luminous intensity), and arc is the lighting angle scope that light source produces via lens arrangement to the coordinate representative.Please also refer to Fig. 4 and Fig. 8.
Thus, each opticpath institute produce an effect from Fig. 4 just can display in Fig. 8, that is the light that projects from the storage tank 112 of pedestal 110, after compiling via the first surface S1 of cylinder 120, just can project equably lens arrangement 100 at the second curved surface S2, the 3rd curved surface S3, the first inclined-plane P1 and the second inclined-plane P2 of umbrella body 130, and its projection scope is greater than 180 degree.
In addition, refer again to Fig. 2 and Fig. 3, umbrella body 130 also comprises one the 3rd inclined-plane P3, and it is symmetrically around central shaft C1 and between first surface S1 and the second inclined-plane P2.In the present embodiment, the 3rd inclined-plane P3 and projection plane P4 press from both sides an acute angle T2, and the scope of this acute angle T2 is that 0 degree is to 15 degree.It is in order to the draft angle as lens arrangement 100,, can successfully separate between products formed and the mould by behind the plastic rubber ejaculate molding in order to lens arrangement 100.Similarly, refer again to Figure 1A and Fig. 3, lens arrangement 100 also comprises a bending side 140, and it is symmetrically around central shaft C1 and between the first surface S1 and pedestal 110 of cylinder 120.This bending side 140 also is to be convenient to lens arrangement 100 behind plastic rubber shaping, and it can successfully separate with mould and make.
In addition, refer again to Figure 1A and Figure 1B, in the present embodiment, lens arrangement 100 also comprises two locking holes 150, and it is positioned on the pedestal 110, in order to make things convenient for the locking part (not shown) lens arrangement 100 is locked on the platform (not shown).In addition, these locking holes 150 also can be revised moulding to form the gummed section of lens arrangement 100, or with the bottom of the pedestal 110 gummed section (for example pedestal 310 of Fig. 2 A and Fig. 2 lens arrangement that B is illustrated 300) as lens arrangement 100, with this with pedestals 110 and 310 of lens arrangement 100 and 300 then on a platform (not shown).At this, present embodiment is not limited the installing mode of lens arrangement 100.
In sum, in the above embodiment of the present invention, lens arrangement will be collected to from the light of pedestal the umbrella body by the first surface on its cylinder, and and then by the curved surface at umbrella body top and the inclined-plane that is positioned at umbrella side edge, and make light be able to project equably lens arrangement from top and the lateral margin of umbrella body.Therefore, lens arrangement just has ray cast that the directive property light source is produced to the floodlight characteristic greater than the specific visual ranges of 180 degree.
Although the present invention describes as above with embodiment; so it is not to limit the present invention, has in any affiliated technical field and usually knows the knowledgeable, is not breaking away from the spirit and scope of the invention; all can do a little change and retouching, so protection domain of the present invention is when being as the criterion with claims.
