Embodiment 1

[0015] Please refer to FIGS. 2A to 2C at the same time. FIG. 2A is a schematic perspective view of a light source module according to the first embodiment of the present invention. FIG. 2B is a top view of the light source module in FIG. 2A , and FIG. 2C is a schematic view along FIG. 2B The sectional view of the light source module viewed by the sectional line 2C-2C'.

[0016] In FIGS. 2A˜2C , the light source module 200 includes a circuit board 202 , a light emitting diode 204 and a light guide cover (shell) 206 . The LED 204 is disposed on the circuit board 202 for providing light. The light guide cover 206 is disposed on the circuit board 202 to cover the LED 204 , and the light guide cover 206 has a first light export port 208 and a second light export port 210 opposite to each other.

[0017] If further subdivided, the light guide cover 206 includes a first arc-shaped light guide cover 212 and a second arc-shaped light guide cover 214 . One end of the first arc-shaped ...

Embodiment 2

[0022] Please refer to FIG. 3 , which shows a top view of a light source module according to a second embodiment of the present invention. The light source module 400 includes a circuit board 402 , a row of light source groups 404 , light guide plates 406 and 408 , and several light guide covers 206 as described in the first embodiment. The row of light source groups 404 has several light emitting diodes 204 described in the first embodiment, and is arranged on the circuit board 402 . The light guide plates 404 and 406 are disposed outside two sides of the row of light source groups 404 .

[0023] Because the LEDs 204 are arranged in a straight line, two adjacent LEDs 204 will form an invalid light emitting area between them. In order to eliminate the existence of the invalid light emitting area, each light emitting diode 204 is covered with a corresponding light guide cover 206 respectively. In other words, each light guide cover 206 is disposed on the circuit board 402 to ...

Abstract

A light source module includes a CB, a light emitting diode and a light conduction shell which is matched on the CB in the way of covering the diode and has related first and a second light conduction ports at both sides of the diode and leads the light of the diode to emit to outside forming two-way conduction lights through the two ports.

Description

【Technical field】 [0001] The present invention relates to a light source module, and in particular to a light source module capable of guiding light in two directions. 【Background technique】 [0002] Light Emitting Diode (LED) has many advantages, such as fast response speed, long luminous life, small size, low power consumption, low heat generation and high reliability, so it has gradually become the main light emitting diode of backlight modules. components. Among them, many light emitting diodes can be arranged into an array light source module. [0003] Please refer to FIG. 1 , which shows a partial top view of a conventional light source module. In FIG. 1 , the light source module 100 at least includes a circuit board 101 and several LEDs 102 . These LEDs 102 are arranged in a straight line, like a row of light source groups, and are disposed on the circuit board 101 . Since the light provided by each LED 102 is scattered at 360 degrees, when the LEDs 102 are arrang...
