Abstract

A laser remote receiving device is provided, which comprises a photographic sensitive element; outside the photographic sensitive element, a diffusing cap is housed; the diffusing cap is a translucent cap body made of macromolecule resin material, shape of which can be spherical or hemispherical. The utility model has advantage of simple structure, so that if only laser signals aim at the diffusing cap, the photographic sensitive element can sense, so that the photographic sensitive face of the laser remote receiving device can be expanded by several times; laser in rather long transmitting distance can fulfill photographic sensitive target for the photographic sensitive element, so that the laser remote device can be used more conveniently and makes for development of household automation.

Description

Laser remote-controlled receiving trap

Technical field

The utility model relates to the photoelectricity telechiric device, relates in particular to a kind of receiving trap of laser remote control system.

Background technology

Existing laser remote-controlled device, the light-sensitive surface of its receiving trap photo-sensitive cell is generally all very little, has only several square millimeters mostly, and so little light-sensitive surface is when receiving the long distance laser signal, and light signal is difficult to accurately beat on light-sensitive surface, thereby uses very inconvenient.On the other hand, electrical equipment in the family is more and more, people wish to utilize a telepilot these household electrical appliances of remote control easily, but owing to be subjected to remote control to receive the restriction of photo-sensitive cell light-sensitive surface, are difficult under the situation that the phase mutual interference does not take place all electrical equipment in the remote control visual field.

Summary of the invention

The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and a kind of laser remote-controlled receiving trap easy to use is provided.

The laser remote-controlled receiving trap of the utility model comprises photo-sensitive cell, and its design feature is also to be covered with diffuser in the outside of photo-sensitive cell.

Laser remote-controlled as mentioned above receiving trap, its photo-sensitive cell is installed on the substrate, and hemispheric diffuser is installed on substrate.Part in substrate is in diffuser is posted reflective membrane.

Laser remote-controlled as mentioned above receiving trap, its diffuser are spherical, and photo-sensitive cell is arranged on the centre of sphere position of diffuser by support.

The utility model is simple in structure, as long as laser signal is beaten on diffuser, photo-sensitive cell can be responded to, thereby the light-sensitive surface of laser remote-controlled receiving trap can be enlarged several times, remote emitted laser can make photo-sensitive cell sensitization easily, make the use of laser remote controller convenient, also help the development of home automation.

Embodiment

Embodiment illustrated in fig. 1, photo-sensitive cell 1 of the present utility model is installed in the center of circular substrate 4, in substrate 4 one sides hemispheric diffuser 2 is installed, with photo-sensitive cell 1 cover within it, part in substrate 4 is in diffuser 2 is posted reflective membrane 3, to increase light intensity.This structure is fit to be installed on the planar objects such as wall, can be made into the multiple shapes such as ladybug of lying prone on the wall.Diffuser 2 is translucent cover bodies of being made by macromolecule resin material.

Embodiment shown in Figure 2, diffuser 2 are spherical, and two back to together photo-sensitive cell 1 and photo-sensitive cell 1 ' be arranged on the centre of sphere position of diffuser 2 by support 5, and this structure can be made the lantern or the multiple shapes such as the orange in the potted landscape, apple of suspension.

Fig. 3, embodiment illustrated in fig. 4, diffuser of the present utility model is by the main diffuser 2 of the segment shape that combines and the secondary diffuser 2 of billiard table shape ' constitute, main diffuser 2 and secondary diffuser 2 ' the bottom make by opaque material, a plurality of photo-sensitive cells 1 are installed on it, and post reflective membrane to increase light intensity.
