Source, the light source are arranged in spherical outside surface mirror, and the spherical outside surface mirror side is light outlet, installs shadow shield in the outlet,
Optical surface is set in the lower section of the shadow shield, the light that can not be utilized is reflected back into by light source center by optical surface
Near zone.
By the setting of hemispherical optical curved surface, when the isolychn that light source sends passes through this optical surface, it is re-reflected into
The centre of sphere is light source, increased the utilization rate of the overall energy.Would not there is non-productive optical curved surface.
Preferably, the optical surface is spherical calotte, the sphere is with light source as the centre of sphere.Or do not adopt sphere and
Using other forms reflecting surface, also can reach similar light and recycle effect.
Preferably, the optical surface is made from the material with reflection function.
Preferably, the optical surface also includes mounting surface, the mounting surface is fitted with the mounting surface of spherical outside surface mirror, is led to
Cross fastener connection.
Preferably, the fastener is screw or bolt or adopts riveting process.
Preferably, the mounting surface is integrally manufactured with spherical outside surface mirror.
As described above, distance-light one module of the present utility model, has the advantages that：
1, luminous flux improves 13%, and high-high brightness improves 14%.The efficiency of light energy utilization is greatly improved, and performance also has this
The lifting of matter.As luminous flux and center brightness are improved simultaneously, designer allows bigger space to carry out the uniformity of light type
Adjustment.Therefore the market competitiveness is had more using the design of the present invention.
2, reflecting surface can reduce the heat radiation being radiated on shadow shield assembly by reflection light, for the heat of magnetic valve
Stability provides contribution.Particularly in the design of halogen light source module, contribution of the present design to thermal stability can
Can it is critical that.
3, the reflecting surface for newly increasing reduces the space shared by reflecting surface while the efficiency of light energy utilization is increased, and is other knots
The design of structure is provided convenience.

Specific embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages of the present utility model and effect easily.
It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only to coordinate specification to be taken off
The content shown, so that those skilled in the art understands and reads, is not limited to the enforceable restriction bar of the utility model
Part, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not affecting
Under effect that the utility model can be generated and the purpose that can reach, still all should fall in the technology disclosed in the utility model
In the range of Rong get Neng is covered.Meanwhile, in this specification it is cited as " on ", D score, "left", "right", " centre " and " one "
Deng term, be merely convenient to describe understands, and is not used to limit the enforceable scope of the utility model, its relativeness
It is altered or modified, under without essence change technology contents, when being also considered as the enforceable category of the utility model.
In order to describe distance-light one module of the present utility model in detail, have followed by following embodiments work
Body explanation：
Embodiment 1
A kind of distance-light one module according to Fig. 3, including light source 1, light source 1 are arranged in spherical outside surface mirror 2, ectosphere
Mirror 2 side in face is light outlet, installs shadow shield 3, arrange optical surface 4 in the lower section of the shadow shield 3, by light in outlet
Learn curved surface 4 and the light that can not be utilized is reflected back into into light source center near zone.The optical surface 4 of the present embodiment is part ball
Face, sphere is with light source 1 as the centre of sphere.By the setting of hemispherical optical curved surface 4, the isolychn that light source sends is through this optical surface
When, it is light source 1 to be re-reflected into the centre of sphere, increased the utilization rate of the overall energy.Would not there is non-productive optical curved surface.Optics
Curved surface is made from the material with reflection function.Optical surface also includes the installation of mounting surface 5, mounting surface and spherical outside surface mirror 2
Face is fitted, and is connected by fastener 6.Fastener can be adopted from screw, bolt etc securing member, the connection of the present embodiment
Use riveting process.
Due to the setting of shading 3, even if the light in the region still can not be utilized in the case where shadow shield 3 is opened.
Referring to Fig. 4, an extra optical surface 4 is added in module system, using this optical surface will part originally can not be by
The light back for utilizing goes back to the inside of optical system so that the light that this part originally lost can be reused.
Scheme in the design in this way is compared with scheme not in this way：Luminous flux improves 13%, maximum
Brightness improves 14%.As the position that reflecting surface is placed has isolated the blessing device of light source and magnetic valve, thus invention can also have
The heat-resisting situation of the reduction magnetic valve of effect.
Specific technique is to be removed the invalid optical reflection face in former spherical outside surface mirror, and increased one piece effectively
Optical surface 4.The optical surface of new addition is a sphere in this example, all its light for receiving all is returned and is emitted back towards
At its light source center.Due to the reflecting surface that newly increases while having isolated the blessing device and light source of magnetic valve, therefore for improving electricity
The heat resistance of magnet valve has very great help.
The specific original position for determining non-productive optical reflecting surface, is by continuous experimental implementation.First cut off near screening
Spherical outside surface mirror below tabula rasa, the spherical mirror of excision for the purpose of whole lower semisphere, first cut-out radian spherical mirror, Ran Houkai
Light source, it is dark when whether the brightness of the outgoing light of detection is than not cutting off, such as without impact, then cut off non-productive optical curved surface.Then proceed to
Excision, after excision, light is darker, then be resected to effective optical reflection face, thus determines the critical of non-productive optical reflecting surface
Position.
In the same manner, when the left side final position of optical surface is set, using above-mentioned experiment, increase brighter and brighter, until
Brightness after increase is not further added by, then, it may be determined that the left side final position of optical surface.
Further, the optical surface 4 for entirely newly increasing, unique parameter for needing to arrange, is exactly the centre of sphere institute of optical surface
At the place that should be light source position.
Embodiment 2
Referring to embodiment 1, the distance-light one module of the present embodiment can not include mounting structure, the light in structure design
Curved surface 4 and 2 Integral design of spherical outside surface mirror are learned, a part is designed as, so as to remove the mounting structure of centre from.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.Any person skilled in the art all can be carried out to above-described embodiment under without prejudice to spirit and the scope of the present utility model
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in the utility model
All equivalent modifications completed under god and technological thought or change, should be covered by claim of the present utility model.
