This paper first introduces the main non-polar fluorescent lamp products in the domestic market, and analyzes the practical application and energy-saving effects of such products. At the same time, the technology of dimming electrodeless lamp was given a certain explanation, and its practical applicability was analyzed.

Secondly, through the matching of multiple interfaces of the dimming electronic ballast with the digital wireless communication system, cluster lighting control can be effectively performed, such as timing or real-time switching, single-lamp status detection, group arrangement and central console monitoring. Integrated operations such as control. Really make intelligent lighting control a solution for the market.

Finally, the market prospects of the technology and program have been predicted, and the energy-saving effect has been explained.

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.
