Description

Technical Field

[0001] This invention relates to the field of communications, and in particular to an angle-adjustable optical communication transceiver. Background Technology

[0002] In recent years, light-emitting diode (LED) lighting technology has developed rapidly. Compared with traditional lighting sources, white LEDs not only have low power consumption, long lifespan, small size, and are environmentally friendly, but also have advantages such as good modulation performance and high response sensitivity. Utilizing these characteristics, LEDs can be used for lighting while also transmitting network signals modulated onto the visible light beam of the LED for data transmission, realizing a new type of optical wireless communication technology, known as Light Fidelity (LiFi). Visible light communication technology is a new technology that has developed in recent years. Its principle is to use light signals in the visible light band as information carriers to directly transmit light signals in the air. Among them, the most common is to use light as the light source for visible light communication. Due to the faster switching speed of LEDs compared to fluorescent lamps and incandescent lamps, information can be modulated and transmitted by using high-speed modulated light wave signals emitted by large indoor and outdoor displays, lighting equipment, signal devices, or car headlights and taillights equipped with LEDs, which are invisible to the naked eye. Then, photoelectric converters such as photodiodes are used to receive the light signals and obtain information, thus realizing visible light communication. Optical communication network transceivers are a typical application of visible light communication technology. Li-Fi technology means that as long as you have a light bulb, you can get a wireless internet connection. There are approximately 14 billion light bulbs worldwide. In effect, this also means that any streetlight can become an internet access point, increasing internet coverage. Because visible light only travels in a straight line, only people directly in the path of the light can intercept the information, resulting in extremely high security. WiFi, as the primary technology for wireless data transmission, utilizes radio frequency signals. However, radio waves occupy only a small portion of the entire electromagnetic spectrum. And as user demand for wireless internet grows, the available radio frequency spectrum is becoming increasingly scarce.

[0003] However, due to certain limitations of this technology, in order to improve the transmission rate, the optical transceiver generally needs to be pointed at the light source.

[0004] However, there are currently no optical communication transceivers on the market that can be rotated at any angle to align with the light source, which will hinder the promotion and popularization of this technology. Summary of the Invention

[0043] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0044] The inventors, through analysis of existing technologies, discovered that LED (Light-Emitting Diode) lighting technology has developed rapidly in recent years. Compared with traditional lighting sources, white LEDs not only have low power consumption, long lifespan, small size, and are environmentally friendly, but also possess advantages such as good modulation performance and high response sensitivity. Utilizing these characteristics of LEDs, they can be used for lighting while also transmitting network signals modulated onto the visible light beam of the LED for data transmission, realizing a new type of optical wireless communication technology, known in English as Light Fidelity (LiFi).

[0045] Optical communication network transceivers are a typical application of visible light communication technology. Li-Fi technology means that as long as you have a light bulb, you can obtain a wireless internet connection. There are approximately 14 billion light bulbs worldwide. In fact, this also means that any streetlight can become an internet access point, increasing internet coverage. Because visible light only travels in a straight line, only people in the line of light can intercept information, resulting in extremely high security. WiFi, as the primary technology for wireless data transmission, utilizes radio frequency signals. However, radio waves occupy only a small portion of the entire electromagnetic spectrum. And as user demand for wireless internet grows, the available radio frequency spectrum is becoming increasingly scarce. But Li-Fi uses visible light, and its spectrum width is 10,000 times that of the radio frequency spectrum. This means that visible light communication can offer much higher bandwidth. Li-Fi technology can deliver data transmission speeds of up to 1Gbps. However, due to certain limitations, to increase transmission speeds, the optical transceiver generally needs to be pointed directly at the light source, and currently there is no integrated optical communication transceiver device on the market that can be rotated at any angle to align with the light source, which will hinder the promotion and widespread adoption of this technology.

[0046] Therefore, it is necessary to find an integrated optical communication transceiver device that can adjust the angle to align with the light source and thus improve the transmission rate.

The invisible light condenser lens 4 is located on one side of the light-transmitting sheet 2. During communication, the rotating transceiver rotates along the main body of the device to a position where the light from the LED lamp 20 can be received by the light-transmitting sheet 2 and / or to a position where the condenser lens can emit light to the invisible light receiver 21. The photodiode 6 receives optical communication data, and / or the invisible light emitter 5 emits invisible light. By adjusting the angle to align with the light source, the transmission rate is improved. This application is an integrated optical communication transceiver device, compact and convenient, solving the problem that "there is currently no integrated optical communication transceiver device on the market that can be arbitrarily rotated to align with the light source," achieving the technical effect of effectively aligning with the light source.
