Reflecting structure for planar gas discharge lamps
First Claim
1. A reflecting structure for a planar gas discharge lamp comprising:
- a front glass panel located on a light emission side of the planar gas discharge lamp;
a rear glass panel located on a backlight side of the planar gas discharge lamp to form a sealed and hollow chamber with the front glass panel, the chamber being filled with a reaction gas;
at least one pair of electrodes connecting to an inverter to produce a voltage difference to actuate the reaction gas to generate discharge;
a fluorescent material coated on a surface of an inner side of the front glass panel facing the chamber to be actuated by the discharge to generate light, a great portion of the light emitting through the light emission side of the front glass panel;
a light reflective material coated on a surface of an inner side of the rear glass panel facing the chamber to reflect the light passing through the backlight side of the planar gas discharge lamp to the front light emission side; and
a light reflective element located on an outer side of the backlight side of the planar gas discharge lamp to reflect the light passing through the backlight side to the front light emission side to increase light utilization and improve luminance of the light emission side of the planar gas discharge lamp.

Abstract
A reflecting structure for planar gas discharge lamps to improve luminance includes a front glass panel on a light emission side, a rear glass panel on a backlight side, at least one pair of electrodes, a fluorescent layer abutting the light emission side and a reaction gas held between the front glass panel and the rear glass panel. The electrodes have a voltage difference to activate the reaction gas to generate discharge which actuates the fluorescent layer to generate light. The light emits through the light emission side of the front glass panel. The invention further provides a light reflective element to reflect the light passing through the backlight side to the front light emission side to increase light utilization and improve the luminance of the light emission side.
