In order for your fluorescent light fixtures to work properly, you need to have an efficient fluorescent light ballast installed. Running these types of lights is expensive, which is why you need to have one that's in good working order. In order to purchase one, we encourage you to understand how they work. Ballasts for fluorescent lighting works to stabilize the current through the light, and provides the initial striking voltage that is needed to begin the arc discharge. Ballasts for these types of lights are typically expensive, which is why several lights can share one ballast. Begin by testing the high voltage side first. Using your Volt ohmmeter, test the high voltage side for continuity between the wires that go to the light fixtures tombstones. Typically, there is either one or two wires that go to each fixture. Keep in mind that blue or yellow wires indicate power wires and white is the neutral wire. Turn the Volt Ohmmeter to the “ohms” setting and place the ends of the two probes together. The meter should indicate a direct short. Next, you need to touch the probes of the meter to one of the white wires and one of the colored wires that come from the ballast. If your ballast is functioning properly, this will show a continuous circuit. If it does not, you will have to replace the ballast. Check all the wire pairs and if they all test working, move on to testing the low voltage side of the fluorescent ballast....

As part of the tunnel road, traveling in order to ensure coherence, both day and night at any time without lighting. Highway tunnel operation and management of electricity has become a heavy burden sector. Global energy increasingly tense, tunnel lighting energy-saving design is an important part of the development impact of highway. Tunnel lighting and general lighting compared to the following questions: 1, the black hole effect when entering the tunnel. Inside and outside the tunnel during the day because large differences in brightness, long distance outside the tunnel, the tunnel entrance showing a black hole phenomenon. 2, into the tunnel after dark adaptation. Car into the tunnel from the bright outside, the eyes take some time to see the interior of the tunnel, that is, "to adapt to lag." 3, low visibility inside the tunnel. As the car exhaust fumes can not quickly dissipate the formation of smog, the light absorption and scattering, reducing visibility. 4, at the exit of the tunnel white hole effect (daytime). As seen through the export of high brightness outside, exports appear to be a bright hole, serious glare. The purpose is to eliminate the tunnel lighting above phenomenon, to ensure safe driving. To this end, the threshold is usually divided into sections tunnel entrance stage, transitional stage, the basic and outlet sections, each section with different lighting to create a safe and comfortable driving conditions. so choose high pressure sodium lamp and ballast....

Fluorescent lamps are reasonably efficient at converting input power to light. Nevertheless, much of the power supplied into a fluorescent lamp-ballast system produces waste heat energy. When a electric current flows through a conductor ( copper wire), it generate a magnetic field. The magnetic field is strongest at the conductor surface and weakens as its distance from the conductor surface is increased. The magnetic field is perpendicular to the direction of current flow and its direction is given by the right hand rule shown below....

EC magnetic ballast for fluorescent lamps, compact fluorescent lamps and the luminaire insets for compact fluorescent lamps UEC are robust and extremely costeffective solutions with long lives. The wide range of low-loss ballast in energy efficiency classes B2 and B1 from James lighting covers all the relevant applications and ensures that the lamps are operated as specified. There are always energy losses fluorescent ballast. These energy losses will generate heat and cause thermal problems. The losses in ballasts are from the following sources: Hysterisis loss from the sweeping of flux from positive to negative and the area enclosed by the loop is the loss. Hysterisis loss is due to the materials intrinsic properties due to the energy used to align and re-align the magnetic domains. You can lower this loss by using a more expansive materials such as TDK PC 44, for example. Eddy current loss from the circulating currents within the magnetic materials due to differential in flux voltage inside the cores itself. This loss is high dependent upon the thickness of the walls of the cores. The higher the switching frequency, the higher will be this eddy current loss. Copper or winding loss. This is also dependent on the wire size, switching frequency, etc. Skin effect and proximity effect will contribute to this loss....

Electronic ballast from James Lighting is noted in particular for its excellent economy, exceptionally level of lighting comfort and impressive. The wide range of units in the PC family, which comply with the requirements of CELMA energy efficiency classes A2 and A3, offer minimum power consumption and cover all the relevant applications with T5, T8 and compact fluorescent lamps. Dimmable ballast operate at higher frequencies and produce larger amount of light while using less energy. The Dimmable component regulates temperature levels so that the bulb lasts longer. With Dimmable ballasts, the flow is low at the initial point and increases when temperature goes up inside the bulb. Research has demonstrated that low pressure sodium lamps, used together with Dimmable ballast, lost between 20 and 25 percent luminescence in 1 year. In comparison, lamps used with other types of ballasts lost more than twice this amount during the same period. The PC PRO, PC Basic, PC INDUSCTRY and PC FOX versions all have characteristics tailored to their specific applications and requirements. Electronic control gear (ECG) operates lamps with high frequency voltages and currents (over 40kHz) - a frequency range that does not interfere with infra-red remote controls for example which operate at 236kHz. Since the ignition voltage is generated internally there is no need for additional starters. With a power factor greater than 0.95 there is also no need for a capacitor to compensate for reactive power. It is important to note that the reliability of Dimmable ballasts may vary depending on the manufacturer. Effective Dimmable ballasts shut down automatically if a damaged or defective bulb is detected or in case of a short circuit. In this manner, safety hazards are avoided....

Fluorescent Tube ends being black, for two reasons: (1) Tube of poor quality, which often appear on the market are often inferior lamps phenomenon - some even have time to start or not start; (2) The fluorescent ballast starting current is too small, too long to start impact; (3) Core ballast starting current is too large impact on the filament, easy to make lamp black and burnt lamps.core Ballasts are produced according to the standard, if used shortly tube ends that blackening, the lamp should be of questionable quality, and ballast irrelevant. Burn Magnetic Ballast is due to appear between the coils burn out due to short circuit or due to excessive temperature rise caused by short circuit caused by the coil. It is mainly due to: (a) have a lot of enameled pinhole (national standard is allowed per m ≤ 25 pcs pinhole) If you happen to be enameled pinhole pinhole between turns on, the voltage will be too high inter-turn short circuit occurs; (2) using the voltage is too high or long-term use in exceptional circumstances, because the voltage on the use of magnetic ballast extremely strict, each additional voltage 10V 35mA operating current will increase about; increased operating current voltage 20V will increase 70mA, 220V voltage if current is 400mA, at 240V voltage current is 470mA, in this case generally does not appear burned, but in exceptional circumstances (ie starter short circuit) lamp long period start conditions, which led to excessive temperature rise occurs burn. (So we usually find that the lamp is not lit or starter for a long time are in a closed state for a long time, you should immediately check whether the aging of the lamp burned out or the starter has been short, you should replace it immediately, otherwise it will cause high pressure sodium ballast high temperature accelerated the aging, seriously affecting their life can appear even burn.)...

A lamp needs energy to light up, but the energy it draws is generally more than it really needs. To get the lamp closer to the necessary amount of energy rather than the excess it takes in, a fluorescent ballast is connected to the lamp. Each ballast type is different but works by adding an electrical load to the lamp and then including a negative resistance and resistors to balance the energy. Inclusion of an electronic ballast will increase lamp life and lower operating costs. Electronic ballasts regulate the electric flow inside the bulb through electronic circuitry. Sometimes referred to as control gear, the electronic ballast limits the current which flows in an electric circuit. This type of ballast is employed to balance the negative resistance to power supplies with positive resistance. As a result, the current is kept at a level that prevents the bulb from burning out. Electronic ballasts may operate in parallel or in a series mode. The series mode is preferred because the failure of a single lamp does not disrupt the working of all other lamps. The high frequency electronic ballast is another type that makes use of electric circuitry. It uses frequencies that are above 20,000Hz....
