Disclosed is a multi-cell electroluminescent lamp assembly (200) with a varying dielectric thickness. The variation in the thickness of the dielectric layer (120a, 120b) is used to control the electric field strength and therefore the brightness and lifetime of each cell (210a, 210b) in the multi-cell lamp. The dielectric layer thickness is selected dependent upon the surface area of a particular cell in a given region of the lamp. Variation of the dielectric thickness can be used to equalize the electric field and the impedance load each cell presents to the power supply. Consequently, each cell in the multi-cell electroluminescent lamp can be adapted to have a similar lifetime to the other cells in the electroluminescent lamp. Alternately variation in the dielectric thickness can be used to produce a single cell or a group of cells with varying brightness. |
