1, the electrodeless fluorescent lamp
In the field of light source and illumination, the electrodeless fluorescent lamp is widely accepted for its long electrodeless life. The light source uses a unique electronic ballast to generate a radio frequency signal, and the ferroelectric core or the characteristic coil couples the alternating electromagnetic field energy into the plasma light-emitting tube, exciting the internal mercury to generate a 253.7 nm ultraviolet line, and finally exciting the inside of the tube wall. The phosphor material produces a visible light output.
The electrodeless fluorescent lamp is further classified into a built-in type and an external type according to the manner in which the ferrite core is installed. The built-in induction lamp is mainly inserted into the spherical bubble cavity in the magnetic core, and the self-excited oscillation circuit of the MHz level is often used to generate the RF signal for the ignition point. This kind of method makes the light source itself difficult to manufacture, and the spherical lamp tube is beneficial to the light distribution design of the lamp, but the EMC (electromagnetic compatibility) of the whole lamp test is difficult to pass the relevant national standards.
In the case of a magnetic core external type electrodeless lamp, the ignition point is started by the magnetic core being placed outside the annular closing lamp. The frequency range is typically on the order of a few hundred KHz. In terms of frequency selection, low frequency means that the core size needs to be increased to increase the inductive value of the whole lamp; while high frequency is difficult to pass the EMC related standard as a bottleneck due to conducted interference and radiation interference. At the same time, the external induction lamp also needs to pay extra attention to the actual temperature of the core, the temperature of the amalgam point and so on. The large light-emitting area makes the surface brightness of the light source lower than that of the HID light source, and the glare is easy to control. However, the lamp selection and light distribution design become another technical subject of the light source.

Single Mode Fiber Patch Cord is a single stand of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission. Single Mode Fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310 or 1550nm. Carries higher bandwidth than multimode fiber, but requires a light source with a narrow spectral width. Synonyms are mono-mode optical fiber, single-mode fiber, single-mode optical waveguide, uni-mode fiber.
Single-mode fiber gives you a higher transmission rate and up to 50 times more distance than multimode, but it also costs more. Single-mode fiber has a much smaller core than multimode. The small core and single light-wave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.Single-mode optical fiber is an optical fiber in which only the lowest order bound mode can propagate at the wavelength of interest typically 1300 to 1320nm
