The specific embodiment
Below will combine accompanying drawing that the present invention is done further detailed description.
See also Fig. 1 to Fig. 3, the light source module 100 that embodiment of the present invention provides comprises light source 10 and lens 20.Said light source 10 can be a kind of in light emitting diode, discharge lamp and the Halogen lamp LED etc.Said light source module 100 can be used in the products such as car light.
Said lens 20 comprise incidence surface 21, first exiting surface 22, second exiting surface 23, the 3rd exiting surface 24 and connect the joint face 25 of first exiting surface 22 and the 3rd exiting surface 24.Said first exiting surface 22, second exiting surface 23 and the 3rd exiting surface 24 are oppositely arranged with said incidence surface 21.
Said incidence surface 21 can be convex surface, concave surface or plane.In this embodiment, said incidence surface 21 is a plane.
Said first exiting surface 22 is a convex surface; Itself and said incidence surface 21 are formed a convex lens portions; This convex lens portions is used to assemble the light that sends from light source 10, and the light that planoconvex lens portion assembles has the less angle of divergence, can be used for realizing the illumination of remote areas.When said light source module 100 is used for car light, can be used for the illumination of car dead ahead and both sides, dead ahead through the light of first exiting surface, 22 outgoing.Said convex lens portions has an optical axis O and a focus that is positioned at said incidence surface 21 1 sides.Said light source 10 is arranged on this along, thereby makes the light of warp first exiting surface 22 outgoing be roughly directional light, so, can reduce the angle of divergence of first exiting surface, 22 emergent raies greatly.In this embodiment, said optical axis O is perpendicular to incidence surface 21.Said first exiting surface 22 has the first relative limit 221 and second limit 222.
Said second exiting surface 23 is positioned at first limit, 221 1 sides of first exiting surface 22.Said second exiting surface 23 is a plane; This second exiting surface 23 with perpendicular to the angle on the plane of said optical axis O greater than the tangent plane of any point on said first limit 221 of the mistake of said first exiting surface 22 and angle perpendicular to the plane of said optical axis O; So; Can make said second exiting surface 23 have stronger light gathering compared to said first exiting surface 22, can be to optical axis O direction deviation thereby make from the light of said second exiting surface 23 outgoing.When said light source module 100 was used for car light, this second exiting surface 23 can be located at the side of first exiting surface 22 away from ground, thereby can reduce the light that shines top, car dead ahead, more effectively utilized the light of light source 10 outgoing.
Said the 3rd exiting surface 24 is positioned at second limit, 222 1 sides of first exiting surface 22.Said the 3rd exiting surface 24 take up an official post a tangent plane with perpendicular to the angle on the plane of said optical axis O less than the tangent plane of any point on said second limit 222 of the mistake of said first exiting surface 22 and angle perpendicular to the plane of said optical axis O; So; Can make said the 3rd exiting surface 24 have relatively poor light gathering compared to said first exiting surface 22, can be to realize the illumination in zone nearby away from the direction deviation of optical axis O thereby make from the light of said the 3rd exiting surface 24 outgoing.Said the 3rd exiting surface 24 can be plane or curved surface, and when said the 3rd exiting surface 24 was the plane, its tangent plane was equivalent to itself, and in this embodiment, said the 3rd exiting surface 24 is the plane.When said light source module 100 was used for car light, the 3rd exiting surface 24 can be located at the side of first exiting surface 22 near ground, so, can be used to realize the illumination of ground region nearby from the light of the 3rd exiting surface 24 outgoing.
Please further consult Fig. 4, in this embodiment, said the 3rd exiting surface 24 is the convex surface that central authorities have trench 241, and this trench 241 extends to joint face 25 from the edge of said lens 20, and said the 3rd exiting surface 24 is along said trench 241 axial symmetry.Said trench 241 can with from the light of the 3rd exiting surface 24 central outgoing to trench 241 both sides deviations, thereby can avoid the light of the 3rd exiting surface 24 central outgoing too concentrated.In this embodiment; Said the 3rd exiting surface 24 perpendicular to the area of the projection on the plane of said optical axis O less than said first exiting surface 22 at area perpendicular to the projection on the plane of said optical axis O, thereby more light that can make light source 10 send can be used to carry out the illumination of remote areas.
Said joint face 25 can be with reflecting to optical axis O direction to the light on it from the lens internal radiation, to be used for the remote areas illumination.25 reflections of said joint face can be reached through coating reflectance coating above that from the ability of the light of lens internal radiation on it, or utilize total reflection principle to reach.In this embodiment, be coated with on the said joint face 25 and be coated with reflectance coating, said joint face 25 is parallel to said optical axis O.
In this embodiment, said lens 20 peripheries also are formed with a bulge loop 26, and this bulge loop 26 can supply the fixing structure of lens 20 to control when lens 20 install and fix.
In this embodiment, said second exiting surface 23 has stronger light gathering compared to said first exiting surface 22, and making can be to optical axis O direction deviation from the light of said second exiting surface 23 outgoing, thereby can effectively control the outgoing direction of light of light source 10.In addition, said first exiting surface 22 is formed a convex lens portions with incidence surface 21, and this convex lens portions can shine light on it near optical axis O direction set, to be used for realizing the illumination of remote areas with light source 10; Said the 3rd exiting surface 24 has relatively poor light gathering compared to said first exiting surface 22, thereby makes that departing from said optical axis O from the light of said the 3rd exiting surface 24 outgoing realizes the illumination in zone nearby.So, said lens 20 can either let a part of light of light source 10 realize the illumination of remote areas, can let a part of light of light source 10 realize the illumination in zone nearby again.
It is understandable that, for the person of ordinary skill of the art, can make change and the distortion that other various pictures are answered by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
