Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the present invention one
Section Example, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under the premise of creative work, shall fall within the protection scope of the present invention.
The technical solution provided below in conjunction with attached drawing, each embodiment that the present invention will be described in detail.
Please refer to Fig.1-10, what the embodiment of the present invention disclosed a kind of illuminator matches optical assembly, the illuminator packet
Luminescence unit 100 is included, the working region a of the illuminator is located at the side of the optical axis b of luminescence unit 100.
Described with optical assembly includes spreadlight lens 200 and reflector 300, spreadlight lens 200 be mounted on reflector 300 it
It is interior, and for being located at luminescence unit 100.Spreadlight lens 200 can be to the luminous carry out deviation of luminescence unit 100, in turn
So that the light that luminescence unit 100 is sent out is more towards close to the first reflecting surface 311 and the second reflecting surface 321 described hereinafter
Locate deviation.
Reflector 300 has the first reflecting surface 311 and the second reflecting surface 321, the first reflecting surface 311 and the second reflecting surface
321 are located at the both sides of spreadlight lens 200.First reflecting surface 311 and the second reflecting surface 321 are used for spreadlight lens 200 is inclined
At least partly light projected reflexes to working region a.
Disclosed by the embodiments of the present invention in optical assembly, spreadlight lens 200 is used to be located at luminescence unit 100, can incite somebody to action
The light that luminescence unit 100 is sent out carries out deviation, so that more light direction the first reflecting surface 311 and the second reflectings surface
321 deviations.For the light that luminescence unit 100 is sent out after spreadlight lens 200, more light can be in the first reflecting surface 311 and
It is projected to working region a under the reflection of two reflectings surface 321.It will be apparent that passing through spreadlight lens 200 and reflector 300 with optical assembly
Synergistic effect, the intensity of illumination of working region a can be increased, and then the illumination of current illuminator can be alleviated there are energy point
The unreasonable problem of cloth.
Certainly, it since the intensity of illumination in a of working region increases, and then can be easier to meet the requirements, also just without passing through
Increase the power of illuminator to increase the intensity of illumination in a of working region, it is obvious that this can reduce the work(of illuminator
Consumption.
Referring again to Fig. 1, the first reflecting surface 311 relative to the inclined inclinations angle optical axis b be the first inclination angle C, second
Reflecting surface 321 is the second inclination angle D relative to the inclined inclinations angle optical axis b, and the first inclination angle C can be less than the second inclination angle D.
In actual assembling process, the second reflecting surface 321 can be located at the side larger to light deflection angle of spreadlight lens 200, and
First reflecting surface 311 can be located at the other side of spreadlight lens 200.The side smaller to light deflection angle of spreadlight lens 200
Light selfluminous cell 100 is smaller by being influenced after projecting, this some light is easier to without reflection and directly from reflector
It is projected in 300.Based on this, the first inclination angle C can be less than the second inclination angle D, and the first inclination angle C is smaller, so that first
Reflecting surface 311 is more precipitous, finally enables to the first reflecting surface 311 to intercept more light, finally reflects these light
Into working region a.
As described above, the first reflecting surface 311 can not only play the role of reflection, and light can also be preferably intercepted, made
Obtaining more light can be reflected off.And the second reflecting surface 321 is then in and is closer to the side of working region a, therefore the
Two reflectings surface 321 primarily serve the effect of reflection.More light meeting deviation is in the second reflection under the action of spreadlight lens 200
Side where face 321, in order to preferably play reflex, the width dimensions of the first reflecting surface 311 are less than the second reflecting surface
321 width dimensions.First reflecting surface 311 and the second reflecting surface 321 are as shown in Figure 5 to the reflecting effect of light.The width
Size is spent, refers to reflecting from the direction of 311 to the second reflecting surface 321 of the first reflecting surface or from the second reflecting surface 321 to the first
Size on the direction in face 311.
Referring again to Fig. 1 and 5, spreadlight lens 200 can be offset to the bottom in reflector 300, that is to say, that polarisation
The distance of both sides of the edge of the lens 200 away from 300 width direction of reflector differs.First reflecting surface 311 divides with the second reflecting surface 321
It is not placed in the both sides of spreadlight lens 200.First reflecting surface 311 is along the height in the directions optical axis b and the second reflecting surface 321 along optical axis b
The height in direction is all higher than the height of spreadlight lens 200.Such structure enables to the light penetrated from spreadlight lens 200 more
Ground is reflected by the first reflecting surface 311 and the second reflecting surface 321, and then can be so that more light enter workspace after reflection
In a of domain, the utilization rate of light can be finally further increased.
It should be noted that in the embodiment of the present invention, spreadlight lens 200 is used cooperatively with reflector 300, and then to light
Collective effect.In a kind of specific embodiment, spreadlight lens 200 and reflector 300 are strip structure part, such as Fig. 8 institutes
Show.Certainly, the two is also not limited to strip structure, can also be other structures, such as round, rectangular etc..In spreadlight lens
200 and under the premise of reflector 300 is strip structure, length direction of the spreadlight lens 200 with reflector 300, height side
To consistent with width direction, that is to say, that the length direction of spreadlight lens 200 is consistent with the length direction of reflector 300, partially
The width direction of optical lens 200 is consistent with the width direction of reflector 300, short transverse and the reflector 300 of spreadlight lens 200
Short transverse it is consistent.
In the width direction of reflector 300, the first reflecting surface 311 and the second reflecting surface 321 are relative to spreadlight lens 200
