The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Embodiment one:
Fig. 1 utilizes the multiple light courcess collecting system first example structure figure of paraboloidal mirror for the present invention.As shown in the figure, this utilizes the multiple light courcess collecting system of paraboloidal mirror to comprise some light source L1, L2, L3 ... Ln and a paraboloidal mirror 1.Described each light source is parallel light source.The focus place of the common directive paraboloidal mirror 1 of the parallel rays that each light source sent.Described paraboloidal mirror 1 is fixed on the supportive device.This paraboloidal mirror 1 both can be that parabola concave surface speculum also can be the parabolic convex surface speculum.
Design main points of the present invention are to adopt speculum with the parabola shaped reflecting surface converging device as luminous energy.So-called parabola is a kind of of conic section, is being meant on the mathematics on a plane, to the set of a fixed point F and an equidistant point of boning out l.This fixed point F is parabolic focus, and this boning out 1 is parabolical directrix.One straight line is arranged perpendicular to this directrix 1 and by this focal point F on this plane, be called axis.This axis is this parabolical symmetry axis.The intersection point of this parabola and this axis is called the summit.
(omit concrete derivation herein) as can be known by parabolical mathematical derivation, if the concave surface of speculum is parabola shaped reflecting surface, then any light that is parallel to this parabola axis, when shining the recessed reflecting surface of this speculum, the reflection ray of this light converges on the parabolic focus.Otherwise, if the convex surface of speculum is parabola shaped reflecting surface, then any light that is parallel to this parabola axis, when shining the protruding reflecting surface of this speculum, the reflected ray of this light disperses along the reverse extending line direction of this parabola focus.If the convex surface of speculum is parabola shaped reflecting surface, the light that the focus direction of then any this convex surface reflecting surface of aligning is advanced will be by the parabola shaped reflecting surface reflection of this convex surface, and light reflected will be parallel to the axis of this parabola shaped reflecting surface.
Based on above parabolical geometrical property, for the designed multiple light courcess collecting system that utilizes paraboloidal mirror as shown in Figure 1 of the present invention.No matter paraboloidal mirror is concave mirror or convex reflecting mirror, as long as the light of each light source shines to the focus place of described paraboloidal mirror, paraboloidal mirror all can be with this light along its axis direction reflection.So just can realize that the light that light source sent that some luminous energy densities are less converges the luminous energy that forms the bigger light of luminous energy density and converges purpose.
