平面荧光灯

Abstract

The invention provides a flat fluorescent lamp, belonging to the field of fluorescent lamps. The flat fluorescent lamp comprises two corresponding glass plates, wherein, one glass plates is provided with a groove; the surface of the glass plate having the groove and the other glass plate are contacted and sealed with each other, and the space consisting of the groove forms at least one sealed discharge pipeline; an interior electrode or an external electrode are respectively arranged at two ends of each discharge pipeline; the glass plate surface having the groove is also provided with at least one independent recess; the independent recess forms at least one independent space as a mercury trap after the two corresponding glass plates are contacted and sealed; and the mercury trap is far away from the discharge pipeline and a channel is arranged between the mercury trap and the discharge pipeline. The flat fluorescent lamp can maintain higher luminous efficiency at a higher working temperature.
本发明提供一种平面荧光灯,涉及荧光灯领域,其包括两片对应的玻璃板,其中一片玻璃板上设置有凹槽,该玻璃板的有凹槽面和另一片玻璃板相互接触封合,由凹槽构成的空间形成密封的至少一条放电管道,在每个放电管道两端分别设置有内置式或外置式的电极,在有凹槽的玻璃板面还设置有至少一个独立凹部,在两片对应的玻璃板接触封合后,该独立凹部形成至少一个独立空间作为汞陷阱,该汞陷阱远离所述放电管道且二者之间设置有通道连接。本发明可以在较高的工作温度下保持较高的发光效率。
