  ① Most neon lights use cold cathode glow discharge. When the cold cathode is working, the whole lamp basically does not generate heat, and the efficiency of converting electric energy into light energy is high. Its life span is much longer than that of ordinary fluorescent lamps. For example, the quality can be guaranteed from materials, processing to installation. The life span of neon tubes can be as high as 20000h-30000h. In our country's local standards, it is required to be no less than zaooha cold cathode discharge lamps. The great advantage is that the number of switching times basically does not affect its life, so it is especially suitable for advertising lamps that need to be switched on and off frequently. ②It relies on positive ions bombarding the cathode to make the cathode emit secondary electrons to maintain the discharge, so a certain cathode potential drop is needed to accelerate the positive ions to provide energy, and the cathode potential drop is about 100V-20...

  The best way to use the mosquito killer lamp? Mosquito killers can be divided into electronic mosquito killers and airflow mosquito killers. The mosquito killer lamp has the characteristics of simple structure, low price, beautiful appearance, small size, and low power consumption. Since it does not need to use any chemical mosquito-killing substances when in use, it is a relatively environmentally friendly way to kill mosquitoes. The working principle of the electronic mosquito killer is to use the phototaxis of the mosquito to attract the mosquito and cause it to be electrocuted. The use of a high-efficiency mosquito trap tube has a highly effective attracting effect on mosquitoes and other harmful flying insects. It can instantly kill the fly by electrostatic electric shock. Insects; The electronic mosquito killer lamp circuit is designed to limit current, low power consumption, and high performance. It can be used as long as it is connected to the power supply without any che...

  What is the fish bite alarm ？ Fishing alarm (fish bite alarm) is an electronic product that replaces fish bells. Due to the existence of traditional fish bells during use: the sensitivity is not enough, it is easy to be affected by the wind to produce false alarms, the sound is too small, and there is no luminous indication and it is not conducive to night fishing. It needs to be re-installed every time the rod is thrown, and it is easy to hang the line when fishing. The fishing alarm is produced for the above shortcomings. The fishing alarm is just a product similar to a "fish float" to alert the angler of fish news. It is not an automatic fishing machine that replaces the angler for fishing, so it will not deprive the angler of the pleasure of fishing.
