Electronic Ballast

Q: What does the ballast mean: The first is the utility of the previous power source and the main inverter circuit, and the output inductance and the resonant capacitance independently each carry a lamp tube. Second is that the whole circuit are common, but when I answer the tube with a small h inductor and a small capacity of the ceramics with high pressure to connect two tubes of IC (such as that made of so-called digital intelligent high-power ballast is).

Q: How should the power meter be connected and illustrated: You can't use a multimeter to test with a special instrument.

Q: Process flow of inductance ballast: (A) the inductance ballast is made up of silicon steel sheet, enamelled wire coil, skeleton end cover, bottom plate (case), terminal and so on. (B) : Coil: generates the induced electromotive force. In current situation, because of the coil has certain resistance, can produce electric power, the heat made the temperature rise of inductance ballast, to speed up the ballast aging. To reduce the resistance in the coils, use high purity imported electrolytic copper wire. Silicon steel sheet, the whole conductor is in changing magnetic field, will cause induced current in the whole piece of internal conductors, commonly called "vortexing", it will cause power consumption and temperature rise. In the inductance ballast, in order to enhance the magnetic induction intensity is core, but due to the presence of eddy current, must use a very thin insulation silicon steel sheet of the overlying formation of the core, with each other instead of the whole piece of iron core, to reduce the eddy current loss. Bottom plate: fixed, installed effect.

Q: The role of electronic ballast: Electronic ballast: fluorescent lamp electronic ballast, high-pressure sodium lamp electronic ballast, metal halide lamp electronic ballast. Due to adopt modern soft switch inverter technology and advanced active power factor correction technology and electronic filtering measures, has the very good electromagnetic compatibility, reduces the ballast loss itself.

Q: How do fluorescent lamps remove and install ballast: Pro, hello. The ballast was originally removed. It's the original inductance or the electronic ballast that's broken,

Q: How does this crystal lamp turn on the commutator, where is the ballast?: There are installation instructions! I'll tell you when you buy the lamp!

Q: Is the electromagnetic ballast a inductive ballast?: In the case of fluorescent lamp, there is no electromagnetic ballast, only the inductive ballast and electronic ballast.

Q: The cause of the noise of a fluorescent lamp?: Can unload the fluorescent lamp to first, open the cover of the ballast, then with a knife around the edge of the ballast pick to open a small mouth, will melt wax or resin pouring into the crevice ballast iron core silicon steel sheet

Q: What is the maintenance of the electronic ballast for the energy-saving lamps and the schematics of the circuit diagram?: The electronic energy-saving lamp has a type and bare type. There are three series, such as ball, ball and craft, and the first two series are all transparent, engraved, colorful and ivory. It has beautiful appearance, easy to install and not easy to damage the lamp tube, and the collision and so on. The exposed type is H, UH, 3U, 4U, 2D and spiral. According to the luminous color points, can be divided into red, green, blue, yellow (color temperature is 2700 k, belongs to the warm color light, similar to the incandescent light color), white (the majority with 6400 k color temperature, and belong to cool color light, similar to the fluorescent light color); And the lamp of color temperature is 5000K because light color is close to natural light, have no stimulation to the eye, suit the student and meticulous work more. The electronic energy-saving lamp circuit shown in this paper is shown in figure 1, and the chart is shown in figure 2. The circuit has been added with soft start (filament preheating) circuit, which can extend the life of the lamp. It is applied to the lamp and the exterior pin lamp

Q: How many watts is required for the 21W tube fluorescent lamp?: The rectifier is made with fluorescent lights and does not require a single rectifier.
