Abstract
The utility model relates to a light guide column for raising remote-control sensitivity and increasing remote-control range, which is characterized in that the utility model is composed of a transparent cylinder which is convex at one end surface near an infrared sensor. Through the utilization of the utility model luminous reception quantity of the effective part of the infrared sensor can be increased in order to increase the remote-control sensitivity, and the remote-control distance of the utility model can reach more than 10 meters.
Description
The utility model belongs to photocon, and particularly a kind of leaded light post that improves remote-control sensitivity and increase remote control distance is applicable in the receiving system of infrared remote control system.
In the prior art, have in the various instruments, equipment, household electrical appliance etc. of function of infrared remote control, the part of light conducting in the receiving system of its infrared remote control system, the general employing by the PMMA organic glass made the leaded light post that (the PMMA index of refraction is 1.49), inner face are plane or concave surface, be arranged on the casing, inner face and infrared remote receiver are adjacent; Because the inner face of leaded light post is plane or concave surface, when infrared light passed leaded light post directive infrared remote receiver, infrared light disperseed, and intensity is lower, and therefore, remote-control sensitivity is lower, and remote control distance is shorter, generally only about 8 meters; If will improve remote-control sensitivity and increase remote control distance, what adopt usually is: increase the emissive power of remote control transmitter infrared light, increase the sensitivity of infrared remote receiver, improve the mode of increase costs such as circuit.
The purpose of the utility model is intended to overcome above-mentioned deficiency of the prior art, by changing the shape of leaded light post inner face, can effectively improve remote-control sensitivity and the leaded light post that increases remote control distance thereby provide a kind of.
Content of the present utility model is: a kind of leaded light post that improves remote-control sensitivity and increase remote control distance, constitute by transparent cylinder, and its feature part is: an end face of the close infrared remote receiver of described transparent cylinder (1) (being inner face) is convex surface (2).
Convex surface described in the utility model content (2) can be an arc surface.
Convex surface described in the utility model content (2) can be parabolic.
The support (3) that connects or be connected as a single entity is arranged on the transparent cylinder described in the utility model content (1), 2 connection holes of symmetry are arranged on this support (3).
Compared with prior art, the utlity model has following characteristics:
(1) under the identical situation of the infrared light power of remote control transmitter emission, adopt the leaded light post that is convex surface by infrared remote receiver one end face, make the infrared light that passes leaded light post directive infrared remote receiver converge at effectively being subjected in the optical range of infrared remote receiver, the light income of infrared remote receiver active component (no matter being incident light vertical incidence or out of plumb incident) increases, thereby obviously improve remote-control sensitivity, increase remote control distance, reach 10-15 rice;
(2) increase cost seldom, only need make improvements the leaded light post mold slightly and get final product, and are easy on the technology implement, and practical, result of use is good.
Fig. 1 is a kind of user mode figure of leaded light post in the prior art;
Fig. 2 is the utility model master TV structure synoptic diagram;
Fig. 3 is the utility model plan structure synoptic diagram;
Fig. 4 is a kind of user mode figure of the present utility model;
Fig. 5 is the utility model embodiment master TV structure synoptic diagram;
Fig. 6 is the utility model embodiment plan structure synoptic diagram;
Among the figure: the transparent firmly body of 1-, 2-convex surface (promptly leaning on an end face of infrared remote receiver, inner face), 3-support, 4-connection holes, 5-infrared remote receiver, 6-casing, 7-infrared light, 8-plane inner face.
Embodiment: referring to accompanying drawing 4-6.A kind of be used in the Changhong D2116 color TV set, improve remote-control sensitivity and increase the leaded light post of remote control distance, by the transparent cylinder 1 that is arc surface 2 near an end face of infrared remote receiver, constitute with the be connected as a single entity support that 2 symmetrical connection holes 4 are arranged 3 of global formation of transparent cylinder 1; During use, the leaded light post is installed on the colour TV receiver enclosure 6 by its support 3, and arc surface 2 one ends of leaded light post are near infrared remote receiver 5; Major parameter: infrared remote receiver 5 effective sensitive area field width 5mm, leaded light column diameter 6mm, leaded light post and infrared remote receiver 5 spacing 0.5mm, the arc surface 2 radius 5mm of leaded light post.During use, remote-control sensitivity improves a lot than prior art, and remote control distance increases to more than 10 meters, considerably beyond the standard of 7 meters of national regulations, and televisor (comprising telechirics) is not had any harmful effect.
The utility model is not limited to the foregoing description, and the utility model content is described all can implement and have good result.
