Coil electrode fluorescent electric-discharge lamp pipe

Abstract

In a coil electrode fluorescent electric-discharge lamp pipe (1), a fluorescent film (8) is formed on the inner surface of a glass pipe (2) on positions to which coil electrodes (3, 4) are opposed. The pipe (1) can use the entire glass pipe (2) as a fluorescent electric-discharge region. The pipe (1) can provide illumination with high light intensity. The coil electrodes (3, 4) are constituted by forming an insulating coating electric wire in which the periphery of an electric wire (9) is covered with an insulating layer (10) in the shape of a winding, and consequently the electric wire (9) for the electrode is wounded on the glass pipe (2) via the insulating layer (10) and an electric-discharge phenomenon never occurs between the electric wire (9) and the surface of the glass pipe (2). This prevents reduction in the life of the fluorescent electric-discharge lamp pipe caused by a pinhole formed by the electric-discharge phenomenon. Thus, the long life of the fluorescent electric-discharge lamp pipe can be achieved. Further, the long life is achieved since an illumination efficiency is not deteriorated, and significant power saving can be realized under efficient power consumption.

Description

technical field [0001] The present invention relates to a coil electrode fluorescent discharge lamp in which a coil electrode as an external electrode is disposed in a coiled shape on the outer peripheries of both ends of a glass tube coated with a fluorescent film on the inner surface, and more specifically, the present invention provides a lamp capable of realizing a large Coil electrode fluorescent lamps with reduced power consumption and extended life. Background technique [0002] Overview of Existing Fluorescent Discharge Lamp Tubes [0003] In recent years, a large amount of carbon dioxide gas has been discharged worldwide as a problem due to global warming. One of the causes of large amounts of carbon dioxide emissions is carbon dioxide gas from power stations that use fossil fuels. Light up the darkness at night as bright as day (average of 10 per unit area and unit time 22 photons), use a large amount (about a quarter) of the electricity generated from the power...

Since existing researchers and technicians interpret the detected light as a gas discharge, the distinction between luminescence and ionization due to inelastic collisions of gas atoms caused by moving electrons cannot be clearly explained
