    Fluorescent lamp Cyberphysics

    The inside of the fluorescent tube, or bulb, is coated with a powder such as Sr 5 (PO 4) 3 F mixed with small amounts of rare earth elements. This powder (commonly called a phosphor, although it may not have any phosphorus in it) gives off the white light we see through a process called fluorescence, which is the basis of the name fluorescent light bulb.The UV photons emitted by the excitation

    Fluorescent Tubes Buying Guide Types, Sizes and Uses

    The fluorescent tube, also referred to as the fluorescent strip or tube light, is a low-pressure mercury vapour gas-discharge tube that converts fluorescence into visible light. This process involves the triggering of mercury vapour via an electric charge, resulting in the appearance of a short-wave ultraviolet light. This then causes the phosphor coating inside the tube to glow.

    Fluorescent Tube Sizes A Guide to T4, T5, T8 & T12 Tubes

    18/01/2019· Fluorescent Tube Sizes Guide. There are 4 different fluorescent light options; T4, T5, T8, and T12. The T stands for tubular and the numbers are an index for the diameter (in inches) of the tube. Most tube lighting will have its size mentioned on an end of the tube. So, in most cases, you won’t have to physically measure the tube’s diameter and length. If the size tag is missing, use the

    Safe Practices for Fluorescent Lamp Storage and Recycling

    When the fluorescent tubes and lamps are recycled, the phosphor powder is put through a distillation process to recover the mercury element. Household Waste Recycling Centre’s or Civic Amenity sites will accept lamp waste from householders. Businesses are responsible for their own waste.

    Fluorescent Tube an overview ScienceDirect Topics

    A typical mercury fluorescent tube consists of a glass tube, and up to 2400 mm long, filled with argon or krypton gas and containing a drop of liquid mercury. A diagram of the tube is shown in Figure 21.17.The interior surface of the tube is coated with a fluorescent powder, the phosphor, which converts the ultraviolet light produced by the discharge into visible light.

    Explain how fluorescent tubes work MyTutor

    Explain how fluorescent tubes work Fluorescent tubes are filled with low pressure mercury, when an electric current is passed through, the electrons in mercury are excited and move to a high energy level, this high level state is unstable and so the electron moves back to its original state, but on doing so, it emits an electromagnetic wave with energy equivalent the difference in energy level.

    nuclear physics Fluorescent lamp to detect ionizing

    This is the basic operating principle behind most radiation detectors, but an off-the-shelf fluorescent lamp tube isn't very well-optimized for few-particle detection. As you have read, a fluorescent lamp works by passing electrical current through a vapor of mercury atoms, which produce a line spectrum with a mixture of visible and ultraviolet light as they de-ionize and relax back towards

    Analysing the causes of blackening of ends of fluorescent

    The efficiency of fluorescent tubes ranges from about 16 lm/W for a 4 W tube with an ordinary ballast, to as high as 95 lm/W for a 32 W tube with modern electronic ballast, commonly averaging 50 to 67 lm/W overall. Most compact fluorescents 13 W or more with integral electronic ballasts achieve about 60 lm/W. Due to phosphor degradation as the lamps age, the average brightness over the entire

    How to Test Fluorescent Bulbs: 9 Steps (with Pictures

    29/03/2019· Be careful handling a fluorescent tube. They’re fragile and have potential to break into shards. 3. Scrub the pins of the electrode with a fine sandpaper. Clear away any corrosion or residue as you rub the pins. Small particles like these restrict the electric current and may be the source of your trouble. Use a cloth or paper towel to remove any loose particles before returning the bulb to
