Light positioning device
View Patent ↗A light positioning device. The light positioning device comprises a light guide plate, a light source assembly and a frame. The light guide plate comprises a protrusion and a recess. The light source assembly is disposed on the protrusion of the light guide plate and abuts the light guide plate. The light source assembly comprises a light source module received in the recess of the light guide plate. The frame is disposed under the light guide plate and light source assembly.
1. A light positioning device, comprising:
a light guide plate, comprising a main body, a protrusion and a recess, wherein the protrusion and recess are formed on one side of the main body, and a thickness of the protrusion is less than that of the main body;
a light source assembly disposed on the protrusion of the light guide plate and abutting the main body of the light guide plate, wherein the light source assembly comprise a light source module and a power transmission member, wherein the power transmission member comprises a printed circuit board (PCB), the light source module is received in the recess of the light guide plate, and the power transmission member is electrically connected to the light source and disposed on the protrusion; and
a frame disposed under the light guide plate and light source assembly.
2. A light positioning device, comprising:
a light guide plate comprising a main body, a protrusion and a recess, wherein the protusion and recess are formed on one side of the main body, and a thickness of the protrusion is less than that of the main body;
a light source assembly disposed on the protrusion of the light guide plate and abutting the main body of the light guide plate, wherein the light source assembly comprises a light source module and a power transmission member wherein the power transmission member comprises a flexible printed circuit board (PCB), the light source module is received in the recess of the light guide plate, and the power transmission member is electrically connected to the light source module and disposed on the protrusion; and
a frame disposed under the light guide plate and light source assembly.
