Abstract

A structure for an infrared ray communication device placed over a lane which encloses a wireless infrared communication device and includes an upper cover for an attachment lens, an attachment lens, a rain shield, a light guiding device, a fixed support for an emitting module, a fixed support for a receiving module, a circuit board socket, a trough for a transformer, fixed hooks, and a rain shield. The device is placed over a path of a passing vehicle, and used to receive infrared rays and to proceed with data transmission.

Claims

1. A structure for an infrared ray communication device placed over a lane of a freeway comprising:

a body having a circuit board socket and a back board inside said body;

a pair of fixed hooks located on an outside rear of said body;

a transformer having a pair of fixed holes and fixed inside said body;

a circuit board fixed in said circuit board socket inside said body;

a fixed support for an emitting module and a light guiding device, said fixed support for said emitting module further comprises a plurality of fixed holes, wherein said fixed support for said emitting module and said light guiding device is fixed on sides of said transformer;

a fixed support for a receiving module, wherein said fixed support for said receiving module is located at an opening of said light guiding device;

an attachment lens whereby said lens is attached to said body; and

a rain shield placed outside of said body;

whereby said light guiding device has a quadrilateral trumpet shape to enhance and centralize the received infrared rays.

2. A structure for an infrared ray communication device placed over a lane as recited in claim 1, wherein said back board inside said body is coated with a metallic material.

3. A structure for an infrared ray communication device placed over a lane of a freeway comprising:

a body having a circuit board socket and a back board inside said body;

a pair of fixed hooks located on an outside rear of said body;

a transformer fixed inside said body;

a circuit board fixed in said circuit board socket inside said body;

a fixed support for an emitting module and a light guiding device, wherein said fixed support for said emitting module and said light guiding device is fixed on sides of said transformer;

a fixed support for a receiving module wherein said fixed support for said receiving module is located at an opening of said light guiding device;

an attachment lens whereby said lens is attached to said body; and

a rain shield placed outside of said body;

wherein said fixed support of said emitting module further comprises a plane A and a plane B, and an included angle between said plane A and said plane B, whereby said included angle is calculated to extend the effective communication distance of the infrared rays.

4. A structure for an infrared ray communication device placed over a lane as recited in claim 3, wherein said back board inside said body is coated with a metallic material.
