Bar shaped luminous intensity distribution spare 20 can have a variety of design forms, and the scheme of present embodiment comprises the incidence zone 23 of extending along its length direction as shown in Figure 2, last echo area 21, following echo area 22 and exiting surface 24; Wherein, incidence zone 23 receives from all incident raies of led light source 11, is projected to light splitting surface 31 after the reflection of last echo area 21 collection unit light splitters, and following echo area 22 collection unit light splitters directly are projected to astigmatism plate 40 after reflecting.The bar shaped luminous intensity distribution spare 20 of this form has realized that fully the light of led light source 11 directly is projected to astigmatism plate 40, has reduced light loss largely.
In the LED of present embodiment light fixture, luminescence component is the form of two symmetries; The astigmatism plate of all luminescence components shares; The small end of its wedge shape space toward each other and be communicated in A place among Fig. 2, an end of its light splitting surface 31 is connected to each other at this connection place A.Especially, the exiting surface 24 of its strip source 11 may be molded to the parallel form of mechanical axis toward each other to setting in the luminescence component of these two symmetries, is convenient to reduce the light fixture integral thickness.
As shown in Figure 2, light splitting surface 31 is the form of a diffusive reflective film, and it is matched with on the light splitting body 30, and the back side of this light splitting body 30 is parallel with astigmatism plate 40, and two of light fixture parallel surfaces have been constructed smooth, slim plane light fixture each other.The cross section of light splitting surface 31 is that the form of straight line also can be camber line, multistage line or the form of curve repeatedly.
Embodiment two:
As shown in Figure 4, a kind of LED lamp with flat luminous effect that present embodiment two is showed has two groups of luminescence components of symmetry in twos, namely contains four groups of strip sources 10 and bar shaped luminous intensity distribution spare 20; The astigmatism plate of all luminescence components (this embodiment does not represent) is same person, and its bar shaped luminous intensity distribution spare 20 joins end to end and is closed figure in four luminescence components, the exiting surface of all bar shaped luminous intensity distribution spares 20 is all towards same center C, and light splitting surface 31 is symmetrically distributed by this center annular radiation.Accordingly, the small end place of the wedge shape space of generation, light splitting surface 31 intersects with astigmatism plate, and the light splitting surface 31 at center C place can be supported in astigmatism plate 40.The LED light fixture of this form has used the many groups of strip sources 10 of symmetry in twos, can realize more high-powerly, because bar shaped luminous intensity distribution spare 20 surrounds closed figure, the uniformity that it is luminous and illumination zone effect be fine simultaneously.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
