20110280036 | LIGHT GUIDE MODULE AND MANUFACTURING METHOD THEREOF - A light guide module includes an elongated bar-shaped light guide member, a light emitting assembly mounted to at least one end of the light guide member, and a reflector partially covering the light guide member and the light emitting assembly. The light guide member has an axially extended hollow bore and a light-guiding structure formed in the hollow bore. The light emitting assembly includes a circuit board shaped corresponding to a cross-sectional shape of the light guide member, at least one light-emitting unit mounted on one face of the circuit board adjacent to the light guide member, and a light-shielding unit extended into the hollow bore. The reflector has one open or light-transmitting side to serve as a light projection side. With the above arrangements, the light guide module can be miniaturized and the light-shielding unit helps in solving the problem of uneven light intensity at the light projection side. | 11-17-2011 |
