Protrusion can adjust exit direction and the light distribution of light.For example, the light that can make to be emitted from lighting module 1 forms dot chart
Case.However, this is not required, for example, in order to obtain continuous pattern, the primary reflection surface 111 in principal reflection portion 11 can use light
Sliding continuous surface, and it is not provided with light distribution protrusion.
In one example, for example, light is from the light exit surface of the smooth exit portion 12 at the light emission side in lighting module 1
121 central area outgoing.Collective optics is for example also extraly equipped with the central area of light outgoing, for warp
The light crossed light chopper and expand outgoing optical range is focused to form the outgoing beam that has collected again, to avoid

In the embodiment of the utility model, two typical light 201 and 202 are such as schematically shown in Figure 5.Light
The light that the collimation plane of near top of 201 expressions by light collimation portion 101 projects after collimating collimation from light exit portion 12, and
And it is projected to the point 21 in the smooth collimation portion 10, the point 21' in the principal reflection portion 11 successively in its light path, most afterwards through institute
The point 21 " stated in light exit portion 12 is emitted.Similarly, light 202 represents the collimation plane near the bottom via light collimation portion 10
The light for collimating and being emitted again from the smooth exit portion 12 after divergently being reflected by principal reflection portion 11, and in its light path
The point 22 in the smooth collimation portion 10, the point 22' in the principal reflection portion 11 are projected to successively, most afterwards through the smooth exit portion 12
On point 22 " outgoing.Since described two typical light 201 and 202 are respectively generally from the upper of the collimation plane of light collimation portion 11
It is incident (i.e. close at top and close at bottom) at lower both sides, and from the light source projects near light collimation portion focal position
Incident beam on to light collimation portion 11 be considered as in the art be collimated into it is parallel with the optical axis of light collimation portion in cross section
Upper continuous collimated light beam, then the principal reflection portion 11 set again after in light path and 12 respective optical surface of light exit portion guide
Afterwards, it is emitted at the light exit surface 121 of light exit portion 12, forms continuous outgoing optical range.It is it follows that accurate from the light
The light (such as rim ray 201 and 202 such as graphical representation of exemplary in Fig. 5) of the edge incidence in straight portion is defined goes out firing table in light
The border of final outgoing optical range at face 121, and the outgoing optical range is more than the incident light model at the smooth collimation portion
Enclose.
However, complete and continuous light exit surface is not essential, for example, in some cases, for application-specific
The demand of occasion, in order to prevent light be emitted from the central area, can be set in the central area of the light emission side of lighting module 1
There are photoresist stopper, rather than light exit surface.
Another embodiment that Fig. 6,7 show lighting module 1' according to the present utility model, itself and above-mentioned such as Fig. 4,5 institutes
Differing only in for embodiment is stated, the main reflecting surface 111' of the principal reflection portion 11' of lighting module 1' is not front lit mould such as
The continuous inwardly protruded curved surface 111 that block 1 has, but the discrete inwardly protruded single hop reflection including Multi sectional is bent
Face, such as the three sections of curves 1111,1112 and 1113 for the projection as shown being on side.And reflected in adjacent single hop
Between curved surface, and possesses the optical axis having along with light collimation portion 10 between light exit portion single hop reflecting curved surface adjacent thereto
Being used for of direction (direction of propagation of namely collimated parallel rays) is spaced the plane that is connected with transition, thus the mistake
The collimated light propagated parallel to it will not be worked by crossing connection plane, be functioned only as between discrete section reflecting curved surface
Connecting portion.
Correspondingly, as shown in fig. 7, show from two of the marginal incident of light collimation portion typical light i.e. at the top of at light
301 and bottom at light 302, incident 301 priority of light is projected to light collimation portion near the top edge of light collimation portion
The point 31 of upside, the topmost of principal reflection portion 11' discrete reflectance curved surface 1113 on point 31', finally from light exit portion 12
Point 31 " on light exit surface 121 is emitted.Similarly, light 302 incident near the bottom margin of light collimation portion is successively thrown
Be incident upon the point 32 on the downside of light collimation portion, principal reflection portion 11' foot discrete reflectance curved surface 1111 on point 32', finally from
Point 32 " on the light exit surface 121 of light exit portion 12 is emitted.Since the plane between adjacent discrete reflectance curved surface does not rise
To the effect of reflected light, in fact, collimated light is projected in whole Discrete Surfaces on the principal reflection portion 11' it
Still continuous light outgoing scope is formed when being guided again towards light exit portion 12 afterwards.Also, it follows that collimated from the light
The light (such as rim ray 301 and 302 such as graphical representation of exemplary in Fig. 7) of the edge incidence in portion is defined in light exit surface
The border of final outgoing optical range at 121, and the outgoing optical range is also significantly greater than the incidence at the smooth collimation portion
Optical range.
For the sake of above example is just for the sake of simple signal, and the optical axis of the light source and the optical axis of the smooth exit portion
And nonessential it is arranged to vertical.Substantially, it is contemplated that for the convenient total reflection at principal reflection portion, then usually so that shining
Incidence angle of the light that bright inside modules are propagated at the reflecting curved surface in principal reflection portion is as big as possible, critical at least above being totally reflected
Angle, then it is generally preferred to the optical axis of the smooth exit portion is arranged with respect to the optical axis of the light source into obtuse angle.Hereinafter

As shown in Figure 7,8, the light source to the optical axis of lighting module and the optical axis of the smooth exit portion is arranged in blunt
Angle, so that at the place of reflecting interface 111 " in principal reflection portion, then between the optical axis of this incident optical device and outgoing optical device
Obtuse angle angled relationships it is more convenient be arranged vertically the incidence angle of relation bigger in forming ratio between the two, be thus more easily implemented and be all-trans
Penetrate.
Correspondingly, as shown in figure 8, show from two of the marginal incident of light collimation portion typical light i.e. at the top of at light
401 and bottom at light 402, incident 401 priority of light is projected to light collimation portion near the top edge of light collimation portion
The point 41 of upside, the point 41' of the reflecting curved surface topmost of principal reflection portion 11', finally from the light exit surface of light exit portion 12
Point 41 " outgoing.Similarly, 402 priority of light incident near the bottom margin of light collimation portion is projected under light collimation portion
The point 42' of foot on the point 42 of side, the reflecting curved surface of principal reflection portion 11', finally from the light exit surface of light exit portion 12
Point 42 " outgoing.Due to the obtuse angle setting that light source optical axis is formed relative to the optical axis of light exit surface, so that in principal reflection
Reflected light on the reflecting curved surface in portion deviates more from the normal of the reflecting curved surface, i.e. offset bigger of the reflecting curved surface to light, together
When also allow for and be more easily implemented total reflection, thus ensure that more fully light reflection and scope more dissipate in terms of two
Reflected light be projected on the light exit surface of light exit portion, be achieved in bigger goes out optical range.
Also, it follows that the light of edge incidence from the smooth collimation portion is (such as such as graphical representation of exemplary in Fig. 7
Rim ray 301 and the border for 302) defining the final outgoing optical range at light exit surface 121, and the emergent light
