Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an optical signal receiving apparatus, and more particularly to an optical signal receiving apparatus capable of expanding a range in which a light source signal can be received and improving reception efficiency.

[0002]

[Prior art]

 The conventional light source signal communication method using infrared light as a light source signal achieves the purpose of wireless communication by a signal emitting action and a signal receiving action between a launching device and a receiving device.However, a photoelectric device is used as a receiving device, and a light source is used. Since the signal is received, the range of receiving the light source signal is narrow, so that when the light source signal is emitted by the emitting device, it must be in a state of facing the receiving device, and the communication range must be within the predetermined range. If not limited, the light source signal emitted by the launching device cannot be transmitted to the receiving device. Therefore, the conventional receiving apparatus has a number of problems due to the above-mentioned limitation in use when actually used for wireless transmission electric appliances.

[0003]

[Problems to be solved by the invention]

 Therefore, as can be seen from the above description, the conventional receiving device has a considerably narrow range in which it can be received, so that when it is applied to wireless communication of many electric appliances, it clearly has limitations in use, inconvenience and defects. Needs to be improved.

[0004]

[Means for Solving the Problems]

 The present invention comprises an annular body, a control unit, a photoelectric element, and a convex lens, covers the annular body above the control unit and the photoelectric element, and uses a structure inside the annular body to transmit a light source signal from the surroundings. A convex lens is provided above the annular body for guiding to the photoelectric element, and the convex lens collects light source signals from top to bottom, provides many transmission directions and angles, and effectively converts the light source signal to the photoelectric element. It is a main object of the present invention to provide an optical signal receiving apparatus characterized in that the receiving range can be increased by transmitting and receiving an annular body and a convex lens so that the receiving efficiency can be improved.

Further, the present invention provides a lens outside the annular body, and focuses a light source signal from the surroundings by the lens so that the signal can be transmitted inside the annular body, thereby further improving the reception effect. The next object is to provide an optical signal receiving device characterized by the following.

[0006]

[Embodiment of the invention]

 1 and 2 are a side cross-sectional view and a plan view, respectively, of the present invention. The present invention provides an optical signal receiving device, which includes an annular body 1, a control unit 2, and a photoelectric element (infrared ray). 1A, a cross-section of the annular body 1 is formed around a vertical axis, as shown in FIG. 1A, and forms an annular body. It is made of a light transmitting material suitable for transmission, has a vertical receiving surface 10 outside the annular body 1, and has a first reflecting surface 11 and a second reflecting surface 12 formed on both upper and lower sides of the receiving surface 10, respectively. These two reflecting surfaces 11, 12 are parallel to each other, and the first reflecting surface 11 and the second reflecting surface 12 are all arranged so as to have a 45-degree inclination angle with respect to the horizontal plane. 1. Provide a curved mass 13 inside 1 and focus on the end of the curved mass 13 Thereby the surface provided 14, the thickness of the curved mass 13 is T, if the arc radius of the inner wall R, the relationship between the arc radius R and the thickness T of the curved mass 13 R ≧ 2T to ing.

Further, the control unit 2 and the photoelectric element 3 are provided at the center of the annular body 1, and the photoelectric element 3 is provided above the control unit 2, and a light source signal received by the photoelectric element 3 is transmitted. After the identification, the control unit 2 performs the processing. Further, a convex lens 4 is provided above the center of the annular body 1, and the photoelectric element 3 is positioned at a light source focusing intersection of both the focusing surface 14 of the annular body 1 and the convex lens 4.

As shown in FIG. 3 and FIG. 4, when the light source signal enters the receiving device (see the light source signal on the right side of FIG. 3 and FIG. 4), the light source signal proceeds toward the photoelectric element 3, Since the position is higher than the photoelectric element 3, the photoelectric element 3 cannot be directly received. Therefore, the light source signal first passes through the receiving surface 10 of the annular body 1, and the incident angle becomes the reflection angle. Using the principle, the first reflection surface 11 and the second reflection surface 12 are parallel to each other, and are all formed at a 45-degree inclination angle with respect to the horizontal plane, so that when the light source signal reaches point A, The light is reflected upward through the first reflection surface 11, reaches point B by the upward reflection, and enters the inside of the curved mass 13 of the annular body 1 by the second reflection surface 12. However, since the thickness T of the curved mass 13 and the arc radius R of the inner wall thereof are designed to satisfy R ≧ 2T, the light source can be smoothly advanced along the arc, and the light source signal is curved. The light reaches the focusing surface 14 smoothly along the arc of the mass 13, and the light source signal is transmitted to the photoelectric element 3 under the guidance of the focusing surface 14.

Further, when the light source signal enters the receiving device (see the light source signal on the left side in FIGS. 3 and 4), the light source signal is not transmitted toward the photoelectric element 3, so that the signal is received by the photoelectric element 3. However, after the light source signal enters the receiving surface 10 of the annular body 1 by the processing described above, the light source signal reaches the point C, and reaches the point D by the upward reflection, and the focusing surface of the annular body 1 The information is transmitted to the photoelectric element 3 under the guidance of 14. Therefore, even if the light source signal is incident from any direction around the ring 1, if the communication efficiency of the light source signal can pass through the internal structure of the ring 1, the signal is received by the photoelectric element 3. Will be able to

Further, since the convex lens 4 is provided above the annular body 1, when the light source signal is from above (see the light source signal from above in FIG. 3), focusing can be performed via the convex lens 4, and the light is diffused. The light source signal approaching is concentrated on the photoelectric element 3 so that the receiving device receives the light source signal from above. According to this invention, the communication direction of the light source signal can be increased, and the photoelectric signal can be effectively communicated to the photoelectric element 3. Therefore, the receiving device can have an effect of expanding the receiving range by the annular body 1 and the convex lens 4, and can improve the receiving efficiency.

Further, as shown in FIG. 5, in the present invention, a lens 15 surrounding the receiving surface 10 may be provided on the receiving surface 10 of the annular body 1. The light source signal from the surroundings can be focused by the lens 15, so that the light source signal passes through the lens 15, so that the forward direction of the light source signal and the horizontal plane are parallel to each other. It can penetrate the internal structure of the body 1 and achieve a more favorable receiving effect.

The optical signal receiving device of the present invention can guide a light source signal from the surroundings to the opto-electrical element 3 through the internal structure of the annular body 1 and the convex lens 4, and provide the lens 15 on the receiving surface 10 to provide the surroundings. The light source signal can be transmitted more smoothly through the internal structure of the annular body 1, and the effect of increasing the reception range can be achieved, and the reception efficiency can be improved. In the case of using it, the reception range becomes wider than the conventional one, the restriction on use is reduced, and the convenience is improved.
