Mobile Telephone

1. A mobile telephone, comprising: a main body defining a cavity; a fixing element removably mounted on the main body, the fixing element defining a hole; a light source received in the cavity; and an optical element directly connected to the fixing element by being inserted into the hole of the fixing element on the main body and located at a pathway of the light source, whereby light emitted from the light source being converged by the optical element.

2. The mobile telephone of claim 1 , wherein the optical element is a collimating lens.

3. The mobile telephone of claim 1 , wherein the optical element comprises a light input surface, a light output surface opposite to the light input surface, and a side surface positioned between and connected to the light input surface and the light output surface, the light input surface comprising a convex surface facing the light source and protruding towards the light source, the light output surface being a planar surface, and the side surface being a total reflective face.

4. The mobile telephone of claim 1 , wherein a central axis of the light source is coaxial to that of the optical element.

5. The mobile telephone of claim 1 , wherein the fixing element comprises a fixing part and two clip parts located at two ends of the fixing part, and the two clip parts being respectively clasped with two edges of the main body.

6. The mobile telephone of claim 5 , wherein the fixing part and the two clip parts are integrally formed with one piece.

7. The mobile telephone of claim 5 , wherein the two clip parts are elastic.

8. A mobile telephone, comprising: a main body defining a cavity; a light source received in the cavity; a fixing element removably mounted on the main body, the fixing element defining a hole; and a collimating lens directly connected to the fixing element by being inserted into the hole of the fixing element and located at a pathway of the light source via the fixing element, whereby light emitted from the light source being converged by the collimating lens.

9. The mobile telephone of claim 8 , wherein the collimating lens comprises a light input surface, a light output surface opposite to the light input surface, and a side surface positioned between and connected to the light input surface and the light output surface, the light input surface comprising a convex surface facing the light source and protruding towards the light source, the light output surface being a planar surface, and the side surface being a total reflective face.

10. The mobile telephone of claim 8 , wherein the fixing element comprises a fixing part and two clip parts located at two ends of the fixing part, and the two clip parts being respectively clasped with two edges of the main body.
