Second, the purpose of the coupler is to transmit high-frequency electromagnetic energy to the bulb body. In order to reduce the attenuation and achieve the best transmission effect, the coupler must be matched with the high-frequency power source, and the magnetic material is needed. It is a soft ferrite. The material is wound around an electromagnetic wave transmission device made of a coil. Magnetic materials have a special function: electromagnetic waves are transmitted inside and their wavelengths are much shorter. However, the magnetic material itself causes loss, and the area of ​​the hysteresis characteristic curve of the magnetic material represents the loss of the magnetic material. The higher the frequency of the electromagnetic wave, the longer the line of the magnetic material moves back and forth along the hysteresis characteristic curve, and the magnetic material molecules are turned back and forth by the electromagnetic wave, and the loss is greater. The larger the loss will inevitably lead to higher heat, so it is not difficult to understand the high heat that occurs in the high frequency intelligent illumination cavity coupler.

Intelligent lighting couplers are required for magnetic materials: low frequency loss, high saturation magnetic induction, high magnetic permeability, high Curie temperature and good temperature stability, and narrow hysteresis characteristics. It is not sensitive to stress, has a small magnetostriction coefficient, and is low in price. Some performance parameters are contradictory. For example, a high magnetic permeability necessarily corresponds to a low Curie temperature point. In fact, looking for a good power ferrite material is to find the best comprehensive balance value of its various technical indicators, depending on whether it is used in a variety of different situations, slightly higher or lower one or a few performance parameters. . We should discard the use of magnetic materials in the coupler, that is, to coil more coils or add a skeleton. This can remove an important source of energy and heat, and the working state of intelligent lighting can be improved. At the same time easier to match.

Third, work hard on the bubble body, cancel the silver paste coating of the anti-blocking electromagnetic wave, and change the glass formula to improve the light transmittance of the bubble as much as possible. In addition, you should consider changing the shape and structure of the bubble, otherwise the high-frequency intelligent lighting can not get out of the predicament, and should make different sizes of bubbles according to the power. It is also possible to make a dual coupler lamp, that is, to use the same power supply with two couplers to drive the same gun. It is also possible to drive two different bubbles, which requires changing the structure of the gun. Because it is the same power source, it works at the same frequency. So there is no interference.

Fourth, work hard on the power supply, make intelligent power supply, the power supply has been made through my two years of research and development, and has been mass-produced.

1. The product consistency of intelligent intelligent lighting power supply is good, and how many watts are kept in the wattage. Can do 200W stable street lamps and mining lamps, not afraid of changes in the working environment and changes in working temperature.

2, can dim, adjust the power.
