Abstract

A light transceiver apparatus comprises a receive module and an emitting module. The emitting module has a control unit with light emitting element. The light emitted from the light emitting element forms a wide-angle light and propagates to the receive module through one or multiple reflection. A plurality of light emitting elements is arranged uniformly and a lens is arranged atop the light emitting elements to provide a wide-angle light in omni-direction. The light from the light emitting element propagates, through direct or indirect transmission path, to the receive module.

Claims

1. A light transceiver apparatus comprising

a receive module;

and

an emitting module having a control unit with at least one light emitting element;

the light emitting element being in inclined or vertical arrangement, the light emitted from the light emitting element forming a wide-angle light and propagating to the receive module through direct or indirect transmission path and through one or multiple reflection.

2. The light transceiver apparatus as in claim 1, wherein the receive module has a light receiving plane facing upward or slantingly.

3. The light transceiver apparatus as in claim 2, wherein the receive module is composed of at least two light receiving planes in series or parallel connection.

4. The light transceiver apparatus as in claim 1, wherein the emitting module further comprises a lens to diffuse the light from the light emitting element and located atop the light emitting element.

5. The light transceiver apparatus as in claim 1, wherein the emitting element is an infrared light emitting diode.

6. The light transceiver apparatus as in claim 1, wherein the emitting element is arranged uniformly on the control unit.
