Manufacturers : Lighting products : Fluorescent lamps
A fluorescent lamp uses fluorescence, which is obtained by exciting a fluorescent substance layer formed on an inner wall of a glass tube with an ultraviolet ray, as a light source. A fluorescent lamp is broadly divided into a hot-cathode type and a cold-cathode type by constituent of the electrodes. In the cold cathode fluorescent lamp (CCFL), the electrodes consist of materials that radiate many electrons due to high voltages applied. In a typical cold-cathode fluorescent lamp, a phosphor particle film is formed on an inner surface of a translucent glass bulb having electrodes arranged at both end portions thereof. In this glass bulb, a mixture of an ionizing gas including mercury and one or two or more kinds of rare gas/gasses are filled. Cold cathode fluorescent lamp has the advantages over the hot cathode fluorescent lamp especially in its much smaller diameter tube, its longer life, and its lower power consumption. Conventional fluorescent lamps require heated electrodes at both ends of the lamp for operation, necessitating a pair of terminals at each end so that a current can heat the filaments constituting the lamp electrodes. Standard fluorescent tubes which are used in the lighting of commercial or domestic premises consist of a tubular bulb where the fluorescent material coating is applied substantially over the entire length of the tubular bulb. The fluorescent material chosen normally emits a white or off white colour so that such a tube can efficiently illuminate a room. Fluorescent lamps comprise a tubular bulb with a fluorescent material coated on the interior surface. The bulb typically contains an inert gas such as Neon, Argon, Krypton or Xenon and electrodes. When the electrodes are energized, a flow of electric current passes through the inert gas. Fluorescent lamps typically include a glass envelope that is coated with a layer of phosphors to convert the ultraviolet radiation (UV) generated within the lamp into visible light. The light output of fluorescent lamps is critically dependent upon mercury vapor pressure (vapor density) within the lamp envelope. The mercury vapor pressure is controlled by the temperature of excess liquid mercury which condenses in the coldest part of the lamp envelope, the so-called "cold spot". Standard T8 lamps utilizing only argon as the inert fill gas have a low lumen efficacy, expressed as lumens per watt of positive column power. These same low-wattage T8 lamps yield reduced positive column power through addition of krypton to the fill gas. The addition of krypton reduces energy consumption in fluorescent lamps because krypton, having a higher atomic weight than argon, results in a lower wattage gradient in the positive column with lower heat conduction losses per unit length of discharge in the lamp.
