Anderson developed many improvements in the fluorescent lamp: short arc fluorescent lamp, fluorescent lamp without ballast, improved electrodes and fluorescent lamp dimming technology. An electric current in the gas energizes mercury vapor which delivers ultraviolet radiation through discharge process and the ultraviolet radiation causes the phosphor coating of the lamp inner wall to radiate visible light. Applications of Compact Fluorescent Lamp. Anderson was a professor at Rensselaer Polytechnic Institute and employee of General Electric with 27 patents 1970 - 1992 related to lamp technology. CFL APPLICATIONS. ballast factor (BF) - The ratio of the light output of a fluorescent lamp or lamps operated on a ballast to the light output of the lamp(s) operated on a standard (reference) ballast. A fluorescent lamp or bulb is a less pressure gas-discharge with mercury-vapor lamp and it generates visible light by using fluorescence. Linear fluorescent lamps are one of the most popular lighting solutions in the world due to their high efficiency, low cost, and the extensive range of applications they can be used for. They are the primary light source in most commercial settings and are also used in many household environments. This cost-effective solution simplifies the circuit, thus speeding design time. This chemical reaction involves mercury vapors and gases, thereby producing an invisible light. The lamp automatically turns on around 6 pm and turns off in the morning. is supplied from an outside source such as a laser or a lamp. INTRODUCTION Fluorescent lamps have applications in most areas of lighting, where they give longer lifetime and lower power consumption for equivalent light output compared to filament bulbs, with the disadvantage of higher initial cost. Mercury in compact fluorescent lamps (CFLs) may not exceed 5 mg per lamp. Authors Chien-Hao Huang 1 , Te-Wen Kuo, Teng-Ming Chen. In other words, the fluorescent lamp is more efficient and cooler than incandescent lamps that produce fluorescence of the phosphor coating. Fluorescents provide a shadow free lighting in all applications. Fluorescent bulbs can provide high light output to light large areas and are well suited for detailed task lighting in Industrial applications. This is especially important in lighting circuits where the designer has to A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. The fastest growing application of fluorescent lighting is in _____. The main priority is general lighting that is functional for the office environment. Description: Ambient Temperature IP 66 LIGHT SOURCE Fluorescent The MHDA series is an aluminum linear fluorescent luminaire that is UL certified for hazardous environments where protection is needed from hazardous gasses, dusts and fibers. The more current flowing through a fluorescent lamp the lower the voltage (unlike a . . An electric current in the gas energizes mercury vapor which delivers ultraviolet radiation through discharge process and the ultraviolet radiation causes the phosphor coating of the lamp inner wall to radiate visible light. Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation.It is a form of luminescence.In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. Compact Fluorescent Lamp Applications. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. Because of this, linear fluorescents are the main bulb used in office spaces in the US. Affiliation 1 Phosphors Research Laboratory and . Principles of Fluorescence . This automatic lighting system can be installed in your home to light the premises using CFL or Fluorescent lamp. . Application note Rev.
