Title:

LIGHT EMITTING DEVICE

Document Type and Number:

WIPO Patent Application WO/2010/005026

Kind Code:

A1

Abstract:

Disclosed is a light emitting device comprising a gastight container (1), a gas, an electron source (2), an anode electrode (3), a control unit (5) and a fluorescent element (4). The gastight container has a gastight property. The gas is confined in the gastight container (1), and is so excited by electrons (500) as to emit a first light (501). The electron source (2) is arranged in the gastight container (1), and is constituted to emit the electrons (500) when a drive voltage is applied thereto. The anode electrode (3) is arranged in the gastight container (1). The control unit (5) is constituted to apply the drive voltage to the electron source (2). The fluorescent element (4) is disposed in the gastight container (1), and is constituted to emit a second light when excited by the first light (501). The electron source (2) is constituted to emit the electrons (500) of an energy distribution having a peak value, when a discharge voltage is applied thereto. The peak value of the energy distribution is higher than the excitation energy of the gas and lower than the ionization energy of the gas.
