It should be noted that when component is referred to as " being fixed on " another component, it can be directly on another component or there may also be component placed in the middle.When a surface be considered as with another surface " opposite ", it represent the two surfaces between be solid.
Unless otherwise defined, all of technologies and scientific terms used here by the article is identical with belonging to the implication that the those skilled in the art of the present invention are generally understood that.Term used in the description of the invention herein is intended merely to describe the purpose of specific embodiment, it is not intended that in the limitation present invention.Term as used herein " and/or " include the arbitrary and all combinations of one or more related Listed Items.
Below in conjunction with the accompanying drawings and embodiment is to lens provided by the invention and the Vehicle lamp structure with the lens is described further.
Fig. 1 ~ Fig. 5 is referred to, the present invention provides a kind of Vehicle lamp structure 100, and the Vehicle lamp structure 100 is housed in the light source 20 in the lens 10 including a lens 10 and at least one.
The lens 10 include an exiting surface 11, the one affixed face 12 and one opposite with the exiting surface 11 and connect the exiting surface 11 and the fully reflecting surface 13 in the affixed face 12.
The exiting surface 11 has flat-shaped.
In the present embodiment, the exiting surface 11 is oval.
In other embodiments, the exiting surface 11 is elongated.
The affixed face 12 is a plane and had flat-shaped.
In the present embodiment, the affixed face 12 is oval.
In other embodiments, the affixed face 12 is elongated.
The size in the affixed face 12 is less than the size of the exiting surface 11.The lens 10 are fixed on vehicle body by the affixed face 12.
Because the exiting surface 11 has flat-shaped, be advantageous to the circular Beam spreading that the light source 20 is sent into flat-shaped hot spot.
The fully reflecting surface 13 is made up of multiple curved surfaces with different radius of curvature, and each curved surface is connected between the affixed face 12 and the exiting surface 11.The number that the curved surface can be designed according to being actually needed, and the radius of curvature of each curved surface, different directions is reflexed to by the light being incident on the correspondence curved surface so that the light hot spot projected from the exiting surface 11 meets car light specification.Due to the fully reflecting surface 13 by the curved surface with different radius of curvature form and from different curve corresponding to lens 10 different zones with different thickness, therefore, it is parallel with the affixed face 12 on the lens 10 and be serrated through its outline of the section of the fully reflecting surface 13.
Multiple micro structure arrays 131 being distributed by rule are also formed with the fully reflecting surface 13, the micro structure array 131 can be the one or more in grid, texture, solarization line etc., to increase the aesthetics of the lens 10, strengthen the surface strength of the lens 10, prevent the transmission of light being incident upon on the fully reflecting surface 13.
It is recessed from the affixed face 12 to the exiting surface 11 formed with least one light entrance structures thereof 14.The light entrance structures thereof 14 is used to house the light source 20.There is the light entrance structures thereof 14 one first incidence surface 141 and one to connect first incidence surface 141 and second incidence surface 142 in the affixed face 12.First incidence surface 141 is located at the top away from the affixed face 12 of the light entrance structures thereof 14, and first incidence surface 141 is the D type strip curved surfaces to the affixed projection of face 12.The bearing of trend of first incidence surface 141 is consistent with the long axis direction of the exiting surface 11.The top (lens 10) of first incidence surface 141 and the light entrance structures thereof 14 is integrally formed.Second incidence surface 142 is located at the side wall of the light entrance structures thereof 14, and second incidence surface 142 is opposite with the fully reflecting surface 13.
First incidence surface 141 is D type strip curved surfaces, is advantageous to expand to the light that light source 20 is sent the hot spot of ellipse.
In the present embodiment, the light entrance structures thereof 14 is an incidence hole.
In other embodiments, the light entrance structures thereof 14 can also enter light groove for one.
In the present embodiment, the size of the light entrance structures thereof 14 gradually increases from first incidence surface 141 to the affixed face 12.
In the present embodiment, the light entrance structures thereof 14 has three.Three light entrance structures thereofs 14 are rounded, and the center of circle of three light entrance structures thereofs 14 is on three angles of an isosceles triangle.
In other embodiments, the quantity of the light entrance structures thereof 14 is not limited to 3, depending on its quantity needs according to the actual requirements.
At least one light source 20 is housed at least one light entrance structures thereof 14.The light source 20 can be bulb, light emitting diode or laser diode etc..
In the present embodiment, the light source 11 is light emitting diode.
Suitably increase the quantity of the light source 20, the total optical power of the Vehicle lamp structure 100 can be lifted.
In the present embodiment, the quantity of the light source 20 is 3, and 3 light sources are housed in 3 light entrance structures thereofs 14 respectively.
In other embodiments, the quantity of the light source 20 is not limited to 3, and its particular number can determine according to being actually needed.
The light trend of the Vehicle lamp structure 100 is as follows：
A part for the light that the light source 20 is sent enters the inside of the lens 10 by first incidence surface 141, directly it is incident upon the exiting surface 11 and is projected from the exiting surface 11, or pass through the reflection of the different curve of the different curvature of the fully reflecting surface 13, it is incident upon the exiting surface 11 and is projected from the exiting surface 11；Another part light enters the inside of the lens 10 by second incidence surface 142, the reflection of the different curve by the different curvature of the fully reflecting surface 13, is incident upon the exiting surface 11 and is projected from the exiting surface 11.
Lens provided by the invention and the Vehicle lamp structure with the lens, 1) utilize following feature：A. fully reflecting surface is made up of the different curve with different radius of curvature, b. first incidence surface of the top relative with the affixed face of light entrance structures thereof formed with a D type prominent to the affixed face, c. exiting surface is flat-shaped (ellipse, strip), is concured to be formed clearly and meet the hot spot of car light codes and standards；2) lens of this case and Vehicle lamp structure need not set up a mirror surface just can reflex to other region by the light that certain region above dead line is required in car light specification, and the optical element of process is few, so as to reduce the loss of light, improves the utilization rate of light.
It is understood that above example is only used for illustrating the present invention, limitation of the invention is not used as.For the person of ordinary skill of the art, the other various corresponding changes and deformation that technique according to the invention design is made, all fall within the protection domain of the claims in the present invention.
