The visible light is coded by pulses or in frequency.

Description

A remote control

Object of the invention

The present invention relates to a remote control for remote operation and regulation of mechanisms various, such as lamps, lighting fixtures, doors garages, entrance gates or others.

Background of the invention

In the market there is a great variety of remote control systems for remote operation of a electronic device or circuit These systems comprise a receiver module and a transmitter module that communicate through a encoded signal of infrared or radiofrequency light. These systems have low directionality and can be operated without the need for the transmitter to face the receiver. This feature generates several problems, since in places where there are several different receivers nearby there is no adequate sensitivity, being able to activate an unwanted receiver; also the dispersion reduces the driving distance when lowering signal strength and possible reflections or interference by foreign elements makes them effective only at very short distances

Description of the invention

The remote control object of the present invention Presents features oriented to provide easy use and safe, since it allows intuitive control by the user and great precision in the selection of the receiver to activate.

This remote includes, like the conventional remote controls, a transmitter module and a receiver module and encoder However, the advantage it provides is that the communication between the sender and the receiver is done through a narrow beam of visible light.

The use of a drive signal in the form of a narrow and parallel or almost parallel beam of light allows the user orient said signal comfortably and safely. The user when the emitter module is activated, it causes the emission of the light beam that be projected on any surface provides a point illuminated with visible light. Thus the user is able to guide the The transmitter of signals to the sensor of the receiver module. At moment of the arrival of the light beam to the sensor the signal decoding and device drive or associated circuit if the code or signal is correct. The signal to be directional and in a very narrow beam can only act on a receiver module, so if there are several nearby modules only the drive signal can be directed towards one of them.

The signal in the form of directional beam of light visible originates from a light emitter that can be a pointer laser or a light source, such as an LED or other diode, with a focusing lens that collimates the signal in a beam of rays substantially parallel. This avoids the dispersion that causes the loss of power with distance, increasing the effective scope of the emitter module.

As mentioned, the signal of communication between sender and receiver must present some kind of selectivity or coding, for this the signal can be pulse encoded by a code generator. Another type Selectivity criteria can be the wavelength (or frequency) or color of the signal that should correspond to the transmitter and that is discriminated in the sensor that works by reception direct from said signal.
