Abstract
The invention relates to a light source module. The module comprises a light source and a plurality of optical fibers. The light source has a light exiting surface. The plurality of optical fibers is arranged on the light exiting surface of the light source. Each optical fiber has a light incoming part contacting the light exiting surface of the light source and a light exiting part opposite to the light incoming part. The light exiting part of each optical fiber faces upward and is bent outward to direct the forward light emitted by the light source around.
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, the light source module that a kind of uniform in light emission is provided is necessary.
A kind of light source module, it comprises light source and multiple optical fiber.This light source has an exiting surface.The plurality of optical fiber is arranged on the exiting surface of this light source, each optical fiber has a light in part contacted with the exiting surface of light source and a light out part relative with light in part, the light out part of each optical fiber upwards and outwards bend, with the forward photoconduction sent by light source to surrounding.
The light that the light source center place of embodiment of the present invention sends to lead surrounding through optical fiber, thus decreases the luminous intensity of central area, and adds the luminous intensity of surrounding, thus makes the uniform in light emission of this light source module.

Main element symbol description
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 first embodiment of the invention provides comprises light source 10 and multiple optical fiber 20.The plurality of optical fiber 20 adjusts for the light sent light source 10.
See also Fig. 3, this light source 10 has an exiting surface 11.In the present embodiment, this light source 10 is light emitting diode.
The plurality of optical fiber 20 is arranged on the exiting surface 11 of this light source 10.In the present embodiment, the plurality of optical fiber 20 is arranged on the edge of the exiting surface 11 of this light source 10, and is arranged in ring-type.The length of the plurality of optical fiber 20 is all identical with shape.Each optical fiber 20 has a light in part 21 contacted with the exiting surface 11 of light source 10 and a light out part 22 relative with light in part 21.The light in part 21 of each optical fiber 20 is perpendicular to the exiting surface 11 of this light source 10, and radially upwards and outwards bend, thus the forward photoconduction sent by light source 10 is to surrounding for its light out part 22.
The light that this light source 10 center sends to lead surrounding through optical fiber 20, thus decreases the luminous intensity of central area, and adds the luminous intensity of surrounding, thus makes the uniform in light emission of this light source module 100.
Refer to Fig. 4 and Fig. 5, the light source module 200 that second embodiment of the invention provides comprises light source 30 and multiple optical fiber 40.The difference of the light source module 100 that this light source module 200 and the first embodiment provide is: the plurality of optical fiber 40 decile is arranged in inside and outside two rings, and these multiple optical fiber one_to_one corresponding inside and outside included by two rings.Because the plurality of optical fiber 40 is arranged in two rings, the photoconduction that can further light source 30 center be sent to surrounding, to increase the luminous intensity of surrounding, thus the bright dipping of the light source module 100 that this light source module 200 is provided compared with the first embodiment evenly.
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.
