Description
Technical field
The present invention relates to a kind of reflectors, more specifically, it relates to a kind of special-shaped reflector for improving light utilization efficiency.
Background technique
After light source multi-pass on existing automobile headlight crosses reflector reflection, then planoconvex lens are diffused, and reach irradiation
The highlighted effect in region, reflector are coated on light source more, but since the light of cup body peripheral rim portion can not reflex to convex lens,
Unless increasing the size of convex lens, but make the manufacture of headlight for vehicles volume bigger in this way, occupied space is big, and using effect is bad；
If cutting off the cup body of outer reflector segment, the utilization rate of light is substantially reduced, light efficiency loss is high, and overall effect is bad.Accordingly,
The invention proposes a kind of special-shaped reflectors for improving light utilization efficiency.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art described above, it is anti-to provide a kind of abnormity for improving light utilization efficiency
Light cup, the feature which has light utilization efficiency high, small in size.
In order to solve the above technical problems, the object of the present invention is achieved like this: a kind of raising light according to the present invention
The special-shaped reflector of utilization rate, including being located at lens rear and part is coated on main reflector on light source, main reflector is by institute
The some light for stating light source transmitting reflexes to lens, and the main reflector is equipped with the residual ray that can not emit light source and reflects
To the virtual outer cup body of lens, there is zero interface between virtual outer cup body and the main reflector, set on the main reflector
There is the secondary reflector one extended from zero interface；
It further include reflector one, the secondary reflector one reflexes to the residual ray that light source emits after reflector one again
Reflex to lens.
The present invention is further arranged to: the two sides of the secondary reflector one are respectively equipped with the secondary reflector extended from zero interface
Two；It further include reflector two, the residual ray that light source emits is reflexed to after reflector two secondary reflection again by the secondary reflector two
To lens.
The present invention is further arranged to: the main reflector includes the cup body one and cup body two of upper and lower split.
The present invention is further arranged to: the radius of curvature of the cup body one and cup body two differs.
The present invention is further arranged to: the main reflector, secondary reflector one, secondary reflector two, reflector one and anti-
The reflective surface for penetrating cup two is smooth surface.
The present invention is further arranged to: the lens are plano-convex lens.
In conclusion the invention has the following advantages:
1. the light that can not be collected to lens passes through time reflector reflecting and collecting again, then reflexes to lens through reflector,
The utilization rate that light is generated to light source is improved, and lens can make smaller, headlight overall volume is smaller, and using effect is more
It is good；
2. the setting of two groups reflectors facilitates the concentration reflecting and collecting to the light beyond zero interface, light is reduced
Loss, further increase utilization rate；
3. main reflector is composed using two parts that reflective surface surface curvature radius does not wait, convenient for die sinking manufacture, table
The more fairing that face can make, more preferably, irradiation is more evenly for reflecting effect.

Fig. 3 is reflective mechanism schematic diagram of the invention.
Specific embodiment
In order to more fully understand those skilled in the art, this tests novel technical solution, below with reference to specific implementation
The preferred embodiments of the invention are described in example, but it is to be understood that these descriptions are intended merely to further illustrate this hair
Bright feature and advantage, rather than to the limitation that the invention patent requires.Based on the embodiments of the present invention, the common skill in this field
Art personnel every other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
The present invention is further described with preferred embodiment with reference to the accompanying drawing.
Referring to shown in Fig. 1 to 3, a kind of special-shaped reflector improving light utilization efficiency involved in the present embodiment, including be located at
10 rear of lens and part is coated on main reflector 30 on light source 20, the part light that main reflector 30 emits the light source 20
Line reflection to lens 10, the main reflector 30 is equipped with the void that the residual ray that light source 20 emits can not be reflexed to lens 10
Quasi- outer cup body 31 has zero interface 32, sets on the main reflector 30 between virtual outer cup body 31 and the main reflector 30
There is the secondary reflector 1 extended from zero interface 32；
It further include reflector 1, the residual ray that light source 20 emits is reflexed to reflector one by the secondary reflector 1
Lens 10 are reflexed to after 40 again.
Further, the two sides of the secondary reflector 1 are respectively equipped with the secondary reflector 2 34 extended from zero interface 32；
It further include reflector 2 41, the secondary reflector 2 34 reflexes to the residual ray that light source 20 emits after reflector 2 41 again
Reflex to lens 10.
In the present embodiment, light source 20 generates light, most of directly to reflex to lens after the reflection of main reflector 30
10, small part reflexes to reflector 1 and reflector 2 41 through reflector 1, secondary reflector 2 34 respectively, finally by again
Secondary reflection is to lens 10.
Further, the main reflector 30 includes the cup body 1 and cup body 2 302 of upper and lower split；Further, institute
The radius of curvature for stating cup body 1 and cup body 2 302 differs, and main reflector 30 uses not equal two of reflective surface surface curvature radius
Part is composed, and convenient for die sinking manufacture, the more fairing that surface can make, more preferably, irradiation is more evenly for reflecting effect.
Further, the main reflector 30, secondary reflector 1, secondary reflector 2 34, reflector 1 and reflection
The reflective surface of cup 2 41 is smooth surface, and more preferably, irradiation is more evenly for reflecting effect.
Further, the lens 10 are plano-convex lens.
The special-shaped reflector according to the present invention for improving light utilization efficiency, by will be unable to collect the warp of the light to lens
Secondary reflector reflecting and collecting again, then lens are reflexed to through reflector, improve the utilization rate that light is generated to light source, and lens
What can be made is smaller, and headlight overall volume is smaller, and using effect is more preferably；By the setting of two groups reflectors, facilitate to super
The concentration reflecting and collecting of the light at zero interface out, reduces the loss of light, further increases utilization rate；It is used by main reflector
Equal two parts are not composed reflective surface surface curvature radius, and convenient for die sinking manufacture, the more fairing that surface can make is reflective
Better effect, irradiation is more evenly.
