Abstract
Disclosed is an optical lens. The optical lens comprises a light-in face, a light-out face and a side face. A containing cavity is formed in the light-in face, the containing cavity is in a circular conical surface shape and is recessed towards the light-out face, and the light-out face and the light-in face are oppositely arranged and protrude in the direction far away from the light-in face. The side face is connected between the light-in face and the light-out face, and an atomization structure is formed on the surface of the side face to enable light to be scattered. Due to the fact that the containing cavity is in the circular conical surface shape and is recessed towards the light-out face, when an LED light source is arranged on the light-in face of the optical lens, the containing cavity which is in the circular conical surface shape enables the light to emit out in the direction far away from the optical axis. Furthermore, for the reason that the atomization structure is formed on the side face, the light emergent from the side face is made to be more uniform through the atomization structure. The invention further provides a light-emitting component using the optical lens.

Technical field
The present invention relates to a kind of optical lens, relate in particular to the uniform optical lens of a kind of bright dipping and apply the light-emitting component of this optical lens.
Background technology
Light emitting diode (Light Emitting Diode, LED) is a kind of optoelectronic semiconductor component that current conversion can be become to particular range of wavelengths.The advantages such as light emitting diode is high with its brightness, operating voltage is low, power consumption is little, it is simple easily to mate with integrated circuit, drive, the life-span is long, thus can be used as light source and be widely used in lighting field.
The optical field distribution of the light source of light emitting diode is lambertian distribution conventionally, and for large-area lighting source, the angle of its divergence of beam is comparatively concentrated.But, in a lot of application scenarios, conventionally need to provide a rising angle greatly and the uniform LED source of bright dipping.Therefore, be necessary for an optical lens of LED source design to change its optical field distribution shape.
Summary of the invention
In view of this light-emitting component that, is necessary to provide the uniform optical lens of a kind of bright dipping and applies this optical lens.
A kind of optical lens, comprising:
Incidence surface, is formed with an accommodating cavity on incidence surface, described accommodating cavity is that taper seat shape and court are recessed away from incidence surface direction;
Exiting surface, is oppositely arranged with incidence surface and towards away from the direction projection of incidence surface; And
Side, is connected between incidence surface and exiting surface, and described side forms atomization structure and makes light scattering.
A kind of light-emitting component, comprising:
Optical lens, comprise incidence surface, exiting surface and side, on incidence surface, be formed with an accommodating cavity, described accommodating cavity is taper seat shape and recessed towards exiting surface direction, exiting surface and incidence surface are oppositely arranged and towards the direction projection away from incidence surface, described side is connected between incidence surface and exiting surface, and side forms atomization structure and makes light scattering; And
LED source, described LED source is arranged on the side away from exiting surface of incidence surface, and the light that described LED source sends, from incidence surface incident, then shines external environment via exiting surface and side.
In above-mentioned optical lens and light-emitting component, by an accommodating cavity is set at incidence surface, institute's accommodating cavity is taper seat shape and recessed towards exiting surface direction.In the time LED source being set near incidence surface, described accommodating cavity will make light towards the direction outgoing away from optical axis.And because side is formed with atomization structure, described atomization structure will make the light homogenising more of outgoing from the side.

Following detailed description of the invention further illustrates the present invention in connection with above-mentioned accompanying drawing.
Detailed description of the invention
Referring to diagram, optical lens of the present invention and light-emitting component are further detailed.
Refer to Fig. 1 to Fig. 2, the optical lens 10 that the embodiment of the present invention provides comprises incidence surface 110, exiting surface 120 and be connected to incidence surface 110 and exiting surface 120 between side 130.Described optical lens 10 make material be selected from Merlon, polymethyl methacrylate and glass one of them.In the present embodiment, described optical lens 10 has an optical axis OO ', and described optical lens 10 distributes axisymmetricly along optical axis OO '.
Described incidence surface 110 is plane, and the middle part of incidence surface 110 is formed with an accommodating cavity 111.Described accommodating cavity 111 is taper seat shape and recessed towards exiting surface 120 directions.In the present embodiment, the central shaft of described accommodating cavity 111 overlaps with the optical axis OO ' of optical lens 10.As required, the height H between summit and the bottom surface of described taper seat is greater than the radius R of bottom surface so that light with larger angle towards optical axis OO ' the direction deviation away from optical lens 10.
Described exiting surface 120 is along the direction projection away from incidence surface 110.As required, the middle part of exiting surface 120 can also further be formed with depression 121, and the direction of described depression 121 from exiting surface 120 towards incidence surface 110 is recessed.
Described side 130 is connected between incidence surface 110 and exiting surface 120.Described side 130 is formed with atomization structure and makes light scattering.As required, described atomization structure can be by the formation of sandblast processing mode.In addition the mode that, described atomization structure also can be processed by electric discharge forms.
Figure 3 shows that the light-emitting component 20 of the above-mentioned optical lens 10 of application.Described light-emitting component 20 comprises optical lens 10 and LED source 210 as shown in Figure 1.Described LED source 210 is arranged on the side away from exiting surface 120 of incidence surface 110.The light that LED source 210 sends, from incidence surface 110 incidents of optical lens 10, then shines external environment via exiting surface 120 and side 130.
In above-mentioned optical lens 10 and light-emitting component 20, owing to being provided with an accommodating cavity 111 on incidence surface 110, described accommodating cavity 111 is taper seat shape and recessed towards exiting surface 120 directions.In the time LED source 210 being set near the incidence surface 110 at optical lens 10, described accommodating cavity 111 is the direction deviation away from optical axis OO ' by the light court that LED source 210 is sent, thereby expands the rising angle of light-emitting component 20.And, because the rising angle of light-emitting component 20 increases, increase corresponding at the light of the side of optical lens 10 130 outgoing.Now, by being formed with atomization structure in side 130, described atomization structure will make the light homogenising more of 130 outgoing from the side.Therefore, above-mentioned optical lens 10 can make from the equalizing light rays of optical lens 10 side 130 outgoing in the rising angle that improves light-emitting component 20, thereby the light that whole light-emitting component 20 is sent is comparatively evenly soft.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
