Abstract
A flat fluorescent lamp structure comprising a first substrate, a second substrate, a wall structure, a phosphor layer, and a discharge gas is provided in the present invention. The second substrate is oppositely assembled to the first substrate to form a sealed space. The wall structure is utilized to separate the sealed space into a plurality of illuminating chambers. A tunnel penetrates the wall structure to communicate the illuminating chambers. In addition, the tunnel divides the adjacent illuminating chamber into a first illuminating sub-chamber and a second illuminating sub-chamber connecting with each other. The phosphor layer is formed on inner surfaces of the illuminating chambers. The discharge gas is filled in the illuminating chambers. A ratio of a length and a cross-section area of the tunnel defines a first coefficient, a ratio of a length and a cross-section area of the first illuminating sub-chamber defines a second coefficient, a ratio of a length and a cross-section area of the second illuminating sub-chamber defines a third coefficient, and a ratio of the first coefficient and the second coefficient or the third coefficient is greater than 1/20.
