Description
Technical field
The present invention relates to a kind of light source module.
Background technology
Compared to traditional light emitting source, light emitting diode (Light Emitting Diode, LED) has the advantages such as lightweight, volume is little, it is low to pollute, the life-span is long, and it is as a kind of novel light emitting source, is applied more and more widely.Such as, the light source of the backlight module of existing display is replaced by light emitting diode gradually.
Existing display backlight module adopts straight-down negative usually, and down straight aphototropism mode set is in order to reduce the use of light emitting diode, and can increase by an expansion optical element again in side on a light emitting diode, the angle of divergence of light emitting diode can expand by this expansion optical element.But the rising angle of the light that light emitting diode only can send by traditional expansion optical element expands, and its bright dipping is also uneven.
Summary of the invention
In view of this, be necessary to provide a kind of rising angle large and the light source module of uniform in light emission.
A kind of light source module, it comprises light source and the lens relative with light source.These lens comprise bottom surface, incidence surface, exiting surface and transparent ball.This incidence surface and this light source are oppositely arranged, and this incidence surface is a curved surface caved in lens interior from the center of bottom surface.This exiting surface is relative with bottom surface, and this exiting surface comprises the concave surface being positioned at center of top and the convex surface being positioned at concave surface periphery, and this this incidence surface direction concave surface facing depression, this convex surface court is away from this incidence surface direction evagination.This transparent ball is contained in this incidence surface, and is oppositely arranged with this light source, has multiple hollow bore in this transparent ball.
The lens of embodiment of the present invention and the light source module of employing this kind of lens, the light that light source center place sends is refracted backward surrounding through the transparent ball of lens and disperses, and, hollow bore in this transparent ball can make light reflect to surrounding further, light after dispersion enters this lens by this incidence surface, and be again dissipated into surrounding through this exiting surface, thus make the uniform in light emission of this light source.

Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Refer to Fig. 1 and Fig. 2, the light source module 100 that embodiment of the present invention provides comprises light source 10 and lens 20.These lens 20 adjust for the light sent light source 10.
See also Fig. 3, these lens 20 comprise bottom surface 21, incidence surface 211, exiting surface 22 and side 23.
This bottom surface 21 is a circular flat.This incidence surface 211 be one from the center of bottom surface 21 to the curved surface of lens 20 inner recess.This incidence surface 211 surrounds a groove, and the axis of incidence surface 211 overlaps with the axis of lens 20.In the present embodiment, incidence surface 211 is an ellipsoid, and its minor axis is positioned in the plane at place, bottom surface 21, and major axis is vertical with bottom surface 21.
This exiting surface 22 is relative with bottom surface 21.This exiting surface 22 comprises the concave surface 221 being positioned at center of top and the convex surface 222 being positioned at concave surface 221 periphery.This concave surface 221 is just to incidence surface 211, and towards this incidence surface 211 direction depression, it arrives the forward light of this concave surface 221 for dispersing.This convex surface 222 is towards away from this incidence surface 211 direction evagination, and it arrives the side direction light of this convex surface 222 for dispersing.Described convex surface 222 is in smoothing junction with described concave surface 221.
This side 23 connects bottom surface 21 and exiting surface 22.In the present embodiment, this side 23 is perpendicular to bottom surface 21.
Please also refer to Fig. 4, a transparent ball 24 is contained in the groove that this incidence surface 211 encloses, and is oppositely arranged with this light source 10.In this transparent ball 24, there is multiple hollow bore 241.In the present embodiment, have seven hollow bore 241 in this transparent ball 24, these seven hollow bore 241 sizes are identical, and are uniformly distributed.The radius of each hollow bore 241 is preferably 0.4mm.Particularly, the center of this transparent ball 24 has a hollow bore 241, and other six equidistant rings of hollow bore 241 should the hollow bore 241 around this center be arranged.This transparent ball 24 is made up of polymethyl methacrylate (polymethyl methacrylate, PMMA).
In the present embodiment, comprise a support bar 30 further, this support bar 30 is for being fixed on the incidence surface 211 of these lens 20 by this transparent ball 24.
This light source 10 is oppositely arranged with the incidence surface 211 of these lens 20, and the bottom portion of groove that the incidence surface 211 being positioned at these lens 20 is formed.In the present embodiment, this light source 10 is light emitting diode, and its end face 11 is coplanar with the bottom surface 21 of these lens 20.Certainly, this light source 10 also can be arranged on the inside grooves of these lens 20, and the bottom surface 21 of its bottom surface and this lens 20 is coplanar.
The light that this light source 10 center sends is refracted backward surrounding through the transparent ball 24 of lens 20 and disperses.Further, the hollow bore 241 in this transparent ball 24 can make light reflect to surrounding further, and the light after dispersion enters this lens 20 by this incidence surface 211, and is again dissipated into surrounding through this exiting surface 22, thus makes the uniform in light emission of this light source 10.
Be understandable that, for the person of ordinary skill of the art, the change and distortion that other various picture answers can be made 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.
