Description
Technical field
The present invention relates to a kind of light source module groups.
Background technology
Compared to traditional light emitting source, light emitting diode（Light Emitting Diode, LED）With light-weight, body
The advantages that product is small, pollution is low, long lifespan, as a kind of new light emitting source, is applied more and more widely.For example,
The light source of the backlight module of existing display is gradually substituted by light emitting diode.
Existing display backlight module generally use straight-down negative, and down straight aphototropism mode set is in order to reducing luminous two
The use of pole pipe can be further added by an expansion optical element in side on a light emitting diode, which can be by the hair of light emitting diode
Angle is dissipated to expand.However, the light-emitting angle that traditional expansion optical element is only capable of the light for sending light emitting diode expands, light extraction is not
Uniformly.
The content of the invention
In view of this, it is necessary to provide that a kind of light-emitting angle is big and the light source module group of uniform in light emission.
A kind of light source module group, including light source and the lens opposite with light source.The lens include bottom surface, incidence surface, go out
Smooth surface and transparent ball.The incidence surface is oppositely arranged with the light source, and the incidence surface is for one from the center of bottom surface to lens interior
Concave curved surface.The light-emitting surface is opposite with bottom surface, which is included positioned at the concave surface of center of top and positioned at concave surface periphery
Convex surface, the concave surface are recessed towards the incidence surface direction, this is convex to face away from the incidence surface direction evagination.The transparent ball is contained in
It in the incidence surface, and is oppositely arranged with the light source, there are multiple hollow bores in the transparent ball.
The lens of embodiment of the present invention and the light source module group using this kind of lens, the light sent at light source center is by saturating
The transparent ball of mirror dissipates around after being refracted, also, the in vivo hollow bore of the hyaloplasmic sphere can further make light to four
Week refraction, the light after disperseing are dissipated into surrounding again by the incidence surface into the lens, and by the light-emitting surface, so that
The uniform in light emission of the light source.

Following specific embodiment will be further illustrated the present invention with reference to above-mentioned attached drawing.
Specific embodiment
It please refers to Fig.1 and Fig. 2, the light source module group 100 that embodiment of the present invention provides includes light source 10 and lens 20.This is thoroughly
The light that mirror 20 is used to send light source 10 is adjusted.
Also referring to Fig. 3, which includes bottom surface 21, incidence surface 211, light-emitting surface 22 and side 23.
The bottom surface 21 is a circular flat.The incidence surface 211 is for one from the center of bottom surface 21 to 20 inner recess of lens
Curved surface.The incidence surface 211 surrounds a groove, and the central axes of incidence surface 211 are overlapped with the central axes of lens 20.In this implementation
In mode, incidence surface 211 is an ellipsoid, and short axle is located in the plane at 21 place of bottom surface, and long axis is vertical with bottom surface 21.
The light-emitting surface 22 is opposite with bottom surface 21.The light-emitting surface 22 is included positioned at the concave surface 221 of center of top and positioned at concave surface
The convex surface 222 of 221 peripheries.The 221 face incidence surface 211 of concave surface, and be recessed towards 211 direction of incidence surface, it is used to dissipate
Reach the positive light of the concave surface 221.The convex surface 222 is towards away from the 211 direction evagination of incidence surface, and being used for diverging arrival, this is convex
The lateral light in face 222.The convex surface 222 is smoothly connected with the concave surface 221.
The side 23 connects bottom surface 21 and light-emitting surface 22.In the present embodiment, the side 23 is perpendicular to bottom surface 21.
Please also refer to Fig. 4, a transparent ball 24 is contained in the incidence surface 211 and encloses in the groove set, and with the light source
10 are oppositely arranged.There are multiple hollow bores 241 in the transparent ball 24.In the present embodiment, have in the transparent ball 24
Seven hollow bores 241, seven 241 sizes of hollow bore are identical, and are uniformly distributed.The radius of each hollow bore 241 is excellent
Elect 0.4mm as.Specifically, there are one hollow bore 241, other six hollow bores 241 for tool at the center of the transparent ball 24
The equidistant hollow bore 241 at the center is set.The transparent ball 24 is by polymethyl methacrylate（polymethyl
Methacrylate, PMMA）It is made.
In the present embodiment, a supporting rod 30 is further comprised, which is used to fix the transparent ball 24
On the incidence surface 211 of the lens 20.
The incidence surface 211 of the light source 10 and the lens 20 is oppositely arranged, and be located at the formation of incidence surface 211 of the lens 20
Bottom portion of groove.In the present embodiment, which is light emitting diode, and top surface 11 and the bottom surface 21 of the lens 20 are coplanar.When
So, which can also be arranged on the inside grooves of the lens 20, and its bottom surface and the bottom surface 21 of the lens 20 are coplanar.
The light sent at 10 center of light source dissipates around after the transparent ball 24 of lens 20 is refracted.Also,
Hollow bore 241 in the transparent ball 24 further can be such that light reflects around, and the light after disperseing passes through the incidence surface
211 enter the lens 20, and are dissipated into surrounding again by the light-emitting surface 22, so that the uniform in light emission of the light source 10.
