Abstract

A frame and a light source module having the same are provided. According to embodiments, there is provided a frame comprising a plurality of bodies spaced apart from one another in one direction and connected to one another by a supporter. The plurality of bodies comprises a light emission window formed at an upper part of a body, a light incidence window formed at a bottom part of the body, and a mounting portion formed between the light emission window and the light incidence window, and including a groove that is formed on an inner wall of the body and is recessed horizontally into the body from the light incidence window.

First claim

What is claimed is:

1. A light source module, comprising:
a circuit board;
a plurality of light sources arranged on the circuit board and spaced apart from one another;
a frame coupled onto the circuit board; and
a plurality of quantum dot disks configured to convert the wavelength of light,
wherein the frame includes:
a plurality of bodies spaced apart from one another in a direction in which the light sources are arranged and having a cavity formed in a center portion of each of the plurality of bodies, and
a supporter connecting the plurality of bodies,

wherein each of the plurality of bodies comprises:
a light emission window formed at an upper part of a body,
a light incidence window formed at a bottom part of the body, and
a mounting portion formed between the light emission window and the light incidence window, and including a groove that is formed on an inner wall of the body and is recessed horizontally into the body from the light incidence window,

wherein the light sources are disposed below a respective cavity of each of the plurality of cavities and each of the plurality of quantum dot disks is inserted into a respective mounting portion of each of the plurality of mounting portions, and
wherein the plurality of bodies and the supporter are made of a same material,
wherein the plurality of bodies are not in direct contact with each other,
wherein the plurality of bodies and the supporter are formed of an elastic material,
wherein each of the plurality of quantum dot disks is fixed into the respective mounting portion of each of the plurality of mounting portions without the aid of an adhesive, and
wherein the circuit board and the supporter are connected with each other with no space therebetween.

2. The light source module of claim 1 , wherein the frame is coupled to the circuit board by a screw.

3. The light source module of claim 2 , wherein the supporter includes coupling holes disposed between adjacent bodies.
