Specific embodiment
In order to deepen the understanding to the utility model, below in conjunction with embodiment, the utility model is described in further detail,
The embodiment is only used for explaining the utility model, does not form the restriction to scope of protection of the utility model.
As shown in Figure 1, the present embodiment provides a kind of aplanatism heavy section casting of automobile tail light, include ontology 1, the ontology
First collimator 2 and second collimator 3 of 1 bottom for front and rear setting side by side, 2 and second collimator of first collimator, 3 lower section point
It is not provided with the first LED light source 4 and the second LED light source 5；1 rear wall of ontology is back reflection face 6, and 1 front end of ontology goes out to be step-like
Smooth surface 7；The back reflection face 6 and the upper surface of 2 and second collimator 3 of first collimator are in 45° angle.First LED light source 4
Light collimated by first collimator 2 after inject in ontology 1, project outside ontology 1 later, then pass through step-like light-emitting surface 7
It is injected into ontology 1, is then projected by back reflection face 6 and light-emitting surface 7；The light of the light of second LED light source 5 passes through second
Collimator 3 is injected after collimating in ontology 1, is projected later by back reflection face 6 and light-emitting surface 7.There is preceding reference in 1 front side of ontology
The light of face 8, the first LED light source 4 and the second LED light source 5 is mapped on the preceding plane of reference 8, the first LED light source 4 and the second LED light
Equivalent optical path before source 5 is mapped on the plane of reference 8.The plane of reference 8 before the arrival of first LED light source, 4 and second LED light source 5
Light is in the equivalent optical path of 1 inside points of ontology, the part equivalent optical path outside ontology 1.The back reflection face 6 is decile parabolic
Face.2 and second collimator of first collimator, 3 bottom is caustic surface, and side wall is paraboloid.The first collimator 2 and
Edge spacing between two collimators 3 is 1mm.The ontology 1 is makrolon material or polymethyl methacrylate material.
The refractive index of the present embodiment heavy section casting is set as n, chooses the first light 9 and the second light 10 respectively from the first collimation
The same position of 2 and second collimator 3 of device is sent out.The light that first light 9 is sent out by the first LED light source 4, first light
9 light paths passed through are L4, L5, L6, L7, L8, wherein L4 and L6 and L7 is heavy section casting inner track, and L5 and L8 are outside heavy section casting
Air path, so total light path and be n* (L4+L6+L7)+L5+L8.Similarly, the second light 10 is sent out by the second LED light source 5
The light gone out, the light path that the second light 10 passes through are that L1, L2, L3, wherein L1 and L2 are heavy section casting inner track, and L3 is outside heavy section casting
Portion's air path, so total light path and be n* (L1+L2)+L3.By designing the height and width of step-like light-emitting surface 7,
Cause L1+L2=L4+L6+L7, L3=L5+L8 is so as to obtain n* (L1+L2)+L3=n* (L4+L6+L7)+L5+L8, i.e. the first light
9 and second light of line, 10 equivalent optical path.All fiber-losses of the plane of reference 8 are the same before so reaching out, are to wait light
Strong distribution, realizes the effect uniformly lighted.
The light of first LED light source 4 is injected after being collimated by first collimator 2 in ontology 1, is projected outside ontology 1 later, then
It is injected into ontology by step-like light-emitting surface 7, is then projected by back reflection face 6 and light-emitting surface 7；Second LED light source 5
The light of light is injected after being collimated by the second collimator 3 in ontology 1, is projected later by back reflection face 6 and light-emitting surface 7；Two
A light projects the equivalent optical path of the plane of reference 8 before arrival, can thus obtain and uniformly light effect；Back reflection face 6 and two
The upper surface of collimator increases the utilization rate of effective sunlight in 45° angle；It is aplanatic in realization using step-like light-emitting surface 7
In the case of reduce the weight and volume of heavy section casting so that heavy section casting is lighter and handier.
