First Claim
Patent Images
1. Portable lamp wherein it comprises communication means for exchanging, with at least another partner portable lamp, identification or configuration data or control instructions, wherein said communication means are used for anti-glare function and wherein the lamp further comprises:
- an IR emitter for periodically emitting data over an IR channel having a first IR beam; and
a control unit which comprises;
sensing means for sensing an IR radiation within a receiving cone which is narrower than said first beam;
processing means for processing the signal representative of the IR information being sensed and for detecting the presence of a second lamp that emits an IR signal;
means for significantly reducing the power generated by said lamp in response to the detection of said partner portable lamp emitting data over the IR channel.

11. Process for controlling the power of the light emitted by a portable lamp comprising a light source allowing the generation of at least one light beam, said portable lamp further comprising means for emitting and receiving data over an IR channel, a receiving cone of said IR channel being narrower than the cone of an emitting beam;
-
and comprising means for controlling said process with a control unit; the process comprising the following steps; emitting a frame of data through said IR channel; receiving a IR signal detected on said receiving cone; detecting a IR signal corresponding to a signal emitted by another lamp emitting on said IR channel; reducing the power of the light of said portable lamp in response to the detection of said another lamp emitting on said IR channel. - View Dependent Claims (12, 13, 14)
