Embodiment Construction

[0039] Such as figure 1 , 2 As shown, the present invention proposes a self-aligning optical fiber-LED coaxial connector, including a front outer sleeve 11 and a rear outer sleeve 13, and an LED base 12 placed in the front outer sleeve 11 and placed The fiber holder and the condenser lens 17 in the outer sleeve 13 at the rear end. The fiber holder consists of a centering ring 15 and a clamping ring 14 . The front end outer sleeve 11 and the rear end outer sleeve 13 are connected by threads.

[0040] The assembly of the present invention adopts an in-line structure, such as figure 2 and refer to image 3 As shown, the assembly can be subdivided into four steps. In the first step, you only need to insert the optical fiber into the rear outer sleeve 13, the clamping ring 14, and the centering ring 15 in sequence; The bit ring 151 contacts; the third step puts the packaged LED base 12, including the LED chip 121, the reflective bowl 122, the radiator 123, the chip lead 124 ...

Abstract

The invention provides an optical fibre-LED coaxial connector comprising a front-end outer sleeve and a rear-end sleeve matched with each other to form a cavity; an LED base is arranged in the front-end outer sleeve; a condensing lens is mounted between the LED base and an optical fibre end portion; an optical fibre fixer is mounted in the cavity for fixing the LED base, the condensing lens and the optical fibre; the optical fibre fixer comprises a centering ring and a clamping ring; the LED is used as input of the condensing lens and the optical fibre is used as a conductor for outputting light rays; an LED chip, a radiator, a chip lead, an electrode lead and a reflecting bowl are packaged on the LED base; the reflecting bowl outputs light to the LED for alignment; the condensing lens focuses light rays into the optical fibre; the centering ring and the LED base are processed accurately to ensure the optical fibre and the LED chip coaxial, thereby effectively improving the coupling efficiency; in addition, the connector has simple and compact mechanical connection structure, and simple and convenient installation and disassembly.

Description

technical field [0001] The invention relates to an optical fiber and LED connector, in particular to a self-collimating optical fiber-LED coaxial connector, which is suitable for various lamps that use LEDs and optical fibers together. Background technique [0002] With the development of the LED industry, LEDs have the advantages of high luminous efficiency, small size, good luminous directionality, and long life, and these just make up for the shortcomings of traditional incandescent lamps such as low energy utilization and excessive volume. Traditional incandescent lamps are gradually withdrawing from the market, and LEDs are gradually being widely used. [0003] In the 1970s, the rise of the optical fiber industry provided people with a new way of transmitting light energy and information. Optical fiber has the advantages of small size, light weight, high transmission efficiency, low loss and easy laying, etc., gradually replacing expensive metal materials as the main c...
