Abstract
The utility model is an apparatus for improving remote-control reception sensitivity, including a light-transferring pole, a receiver, wherein the front-end of the light-transferring pole being provided with a light-transferring head, the external side end-face of the light-transferring head being morn than that of the light-transferring pole. The apparatus increases light-wave receiving surface by setting a light-transferring head, which is benefit for receiving infrared light, in this way, the light-wave can be collected through the large end-face of the light-transferring head, and be transmitted to the receiver, thus the usage effect of the light-wave is improved effectively, thereby the sensitivity of the structure for receiving remote controller signals is improved.
Description
Technical field
The utility model relates to televisor, display etc. and uses infrared remote control reception, the structure of specifically a kind of televisor or display remote receiving end.
Background technology
Telecontrol engineering has become the technology that generally adopts in the current household electrical appliance, as televisor, air-conditioning etc.Infrared remote controller as the TV remote controller of family, need be aimed at the receiving end direction in the time of use, and infrared ray also is a kind of of light in fact, and therefore directivity is arranged.The acceptance point that often needs telepilot is aimed on the electrical equipment fully could remote control, sometimes even aimed at, ineffective remote control problem during spirit when also occurring, this brings inconvenience to the consumer, and has influenced its viewing experience.Common solution is to improve leaded light post receiving plane, to improve receiving angle; The circuit aspect can increase the power of remote control transmitter, or improves the sensitivity of infrared remote control receiver.But these two kinds of methods all have deficiency, and the former is unlimited in the televisor effect of screen level central party for receiver, and the latter has increased the cost of infrared remote control system to a certain extent, and for the ordinary consumption electron-like, this is also inapplicable.
In on March 21st, 2007 disclosed Chinese patent CN2881670Y, pointed out a kind of " increasing the leaded light post of remote control distance and remote control angle ", it is to leave the gap between leaded light post and support, to increase the incident scope, but this gap causes entering of dust and moisture easily, and causes that the performance of internal body components and parts reduces.
The utility model content
Based on above consideration, the utility model proposes a kind of structure that improves the remote control receiving sensitivity, this structure reduces the loss of signal by increasing the receiving angle of remote signal in the transmission course, solve the insensitive problem of remote control receiving end signal.
Therefore, the utility model is achieved in that
A kind of device that improves the remote control receiving sensitivity, it includes the leaded light post, receiver, the front end that it is characterized in that the leaded light post also has the leaded light head, and the outside end face of leaded light head is greater than leaded light post front end face, the outer face of leaded light head can be arc surface face or parabola, leaded light head front end just has more effectively light wave and enters in the light conductor like this, thereby increase signal intensity, be beneficial to the reception of infrared light, light wave can be collected through the large end face of leaded light head like this, be transferred to receiver again, can improve the effect of utilizing of light wave effectively, thereby improve the sensitivity that this structure receives remote controller signal.
Described leaded light head can be convex lens.
Leaded light head trailing flank can be any one in arc surface, parabola, the plane.
The leaded light post is column structure, and it can be cylinder, square column or polygon prism.
The outer setting of leaded light post has the reflection horizon, and the reflection horizon can be to electroplate or spray paint and wait the refraction film of the technology made that improves birefringence, also can be one deck reflective metal film that wraps up.The secondary reflection of light in the leaded light post can be effectively improved in this reflection horizon, improves the effect of compiling of light wave.
The breech face of leaded light post can be the plane, can be arc surface, parabola also, its objective is further last received light is converged, and the reception head that is beneficial to receiver receives signal.
Leaded light post and leaded light head can be structure as a whole, and are convenient to processing and fabricating.
The utility model is by the improvement to receiver leaded light post, solved remote control angle problem less than normal effectively,, do not change the telepilot emission circuit system, under the condition of the parts that do not increase too much control reception, can effectively improve the remote control controlled angle, and the sensitivity of remote control, practical.
And above-mentioned improvement, it is simple in structure, is easy to realize, because the processing and fabricating of leaded light post and leaded light head is very simple, and the cost of raw material is very cheap, does not increase the cost of manufacture of existing televisor.
Description of drawings
Fig. 1 is the utility model first embodiment synoptic diagram;
Fig. 2 is the utility model second embodiment synoptic diagram;
Fig. 3 is the utility model the 3rd embodiment synoptic diagram.
Among the figure: 1 is the casing front side wall, and 2 is leaded light head leading flank, 3 leaded light head trailing flanks, and 4 is the leaded light post, and 5 is infrared remote receiver, and 6 is the leaded light head, and 7 is the reflection horizon, and 8 is light conductor, and 9 is leaded light post breech face.
Embodiment
Describe enforcement of the present utility model in detail below in conjunction with accompanying drawing.
Among Fig. 1, leaded light post 4 and leaded light head 6 are structure as a whole, and constitute light conductor 8 jointly; Infrared signal is received by infrared remote receiver 5 through light conductor 8 backs, and light conductor 8 is made up of leaded light head 6 and leaded light post 4, and the cross-sectional area of its leaded light head 6 is a sector structure, its outer face 2 is greater than the end face of leaded light post 4, be beneficial to the reception of infrared light, generally, leaded light head 6 adopts convex lens.
The outer face 2 of leaded light head 6 can be arc surface face or parabola, and leaded light head trailing flank 3 can be arc surface, parabola, or taper surface as shown in Figure 2.Front end just has more effectively light wave and enters in the light conductor like this, thereby increases signal intensity.The rear end of light conductor 8 is leaded light posts 4, and leaded light post 4 is column, and it can be cylinder, square column or polygon prism.The outer side edges of leaded light post 4 has reflection horizon 7, and reflection horizon 7 can be to electroplate or spray paint to wait and improve the technology of birefringence, also can be one deck reflective metal film that wraps up.The secondary reflection of light in the leaded light post 4 can be effectively improved in reflection horizon 7.
, the breech face 9 of leaded light post 4 can be the plane, as shown in Figure 3, the breech face 9 of leaded light post can be arc surface or parabola also, its objective is further last received light is converged, and is beneficial to infrared remote receiver 5 reception heads signal is received.
Need to prove: have the position, hole that light conductor 8 is installed on the casing front side wall 1, this position, hole cooperates the installation of leaded light head, and front end is big slightly, and the rear end is little, and the shape of position, hole shape and leaded light head 6 adapts, and makes light conductor 8 better locate on casing like this.Like this,, reduce the loss that the light reflection is transmitted midway, can under the situation of using original telepilot, effectively increase the reception of infrared signal, promptly improved remote-control sensitivity preferably by increasing the reception of incident light.
